Description

The present invention relates to a hand hygiene behavior detection system, and is particularly suitable for use in a system for identifying a medical worker performing a hand hygiene behavior.

WHO warns about the five stages of transmission of pathogens through the hands of healthcare workers among medical-related infections, and through guidelines, such as hand washing with soap and running water and hand disinfection with alcohol disinfectants. Enforcement of hand hygiene is recommended. However, many medical institutions have a hand hygiene implementation rate of less than 50%, and the compliance rate is not high.

Therefore, it is required to improve the compliance rate of hand hygiene by sensing the actual condition of whether or not the medical staff is performing hand hygiene at the required timing and feeding back the result to the site. Against this background, by detecting that a discharge operation has been performed on a disinfectant bottle that discharges a disinfectant solution and transmitting predetermined information, disinfection results by medical staff based on the information have been performed. A system for managing the above has been proposed (see, for example, Patent Documents 1 and 2).

In the disinfection record grasping system described in Patent Document 1, a container with a disinfection pump (disinfection bottle) is located around the disinfection bottle based on the discharge operation detection means for detecting the discharge operation and the detection of the discharge operation. It is provided with a discharge completion signal transmitting means for transmitting a discharge completion signal to a name plate (incorporating a communication unit, a control microcomputer, and a storage medium) carried by a managed person (medical worker). Further, the name plate includes a storage medium for storing information on the disinfection record by the managed person, and an update means for updating the disinfection record information based on the received discharge completion signal.

In the in-hospital hand-washing management system described in Patent Document 2, a pressing force on the nozzle head is applied to a rubbing alcohol bottle (rubbing bottle) provided with a nozzle head that discharges rubbing alcohol from a discharge nozzle by a pump mechanism by pressing. A hand-washing management device including a pressure-sensitive sensor that detects the pressure and a communication device that transmits the pressure value detected by the pressure-sensitive sensor together with its own communication device ID is attached, and a disinfecting bottle equipped with the hand-washing management device is placed in the hospital. Place it in a designated place and install a repeater within the range where it can communicate with the communicator of the disinfection bottle with a hand-washing management device. In addition, the medical staff is made to carry a personal ID transmitter that transmits the personal ID at regular time intervals. The repeater receives the personal ID, the communication device ID, and the pressing value from the communication device of the hand-washing management device, and transmits these information to the hospital server together with the repeater ID unique to the repeater. The in-hospital server compares the personal ID and pressing value received from the repeater with the personal information held by the in-hospital server and the predetermined pressing setting value, and the nozzle head is not pushed or pushed for each individual. Is insufficient or has been pushed sufficiently. In addition, the location of the medical staff is specified by comparing the repeater ID with the position information of the repeater that the in-hospital server has inside. Then, the in-hospital server causes the recording device to record those results.

However, in the system described in Patent Documents 1 and 2, if there is another medical worker in the vicinity of the disinfecting bottle in addition to the medical worker operating the disinfecting bottle, the other medical worker concerned There was a problem that the person was also recorded as having been disinfected. That is, in the case of Patent Document 1, the discharge completion signal is also received on the nameplate of another medical worker near the operated disinfection bottle, and the disinfection record information is based on the received discharge completion signal. Will be recorded. Further, in the case of Patent Document 2, the personal ID transmitted from the personal ID transmitter carried by another medical worker near the operated disinfection bottle uses the hand-washing management device and the repeater of the disinfection bottle. It is sent to the in-hospital server via the hospital, and information on disinfection results is recorded.

When there are a plurality of medical workers near the disinfecting bottle operated in this way, as a method of judging the actual operator from among them, there is a method of judging based on the magnitude of the received electric field strength. Conceivable. For example, in the system described in Patent Document 2, in the hand-washing management device that receives the personal ID transmitted from the personal ID transmitter, when the personal IDs related to a plurality of medical professionals are received, the individual having the largest received electric field strength. It is possible to determine that the healthcare professional corresponding to the ID is the actual operator of the disinfectant bottle. In the case of the system described in Patent Document 1, since the nameplate carried by each medical worker receives the discharge completion signal and records the disinfection record information in the internal storage medium, each medical worker is engaged in the system. It is not possible to compare the received electric field strengths on a person's nameplate. Therefore, it is not possible to identify the actual operator from among a plurality of medical staff who have received the discharge completion signal on the nameplate.

By the way, in the system described in Patent Document 2, the hand-washing management device receives the timing at which the pressure sensor of the hand-washing management device detects the pressing force on the nozzle head and the personal ID transmitted from the personal ID transmitter of the medical worker. It is assumed that the timing of the operation is almost the same, and the pressure value against the nozzle head and the personal ID received from the personal ID transmitter are transmitted to the repeater together. However, in consideration of actual operation, in order to reduce the power consumption of the battery of the personal ID transmitter, the personal ID may be transmitted intermittently.

When the personal ID is transmitted intermittently, the timing at which the pressure sensor of the hand-washing management device detects the pressing force on the nozzle head and the personal ID transmitted from the personal ID transmitter of the medical staff are hand-washed and managed. It does not always match the timing received by the device. Therefore, the medical worker may be away from the disinfecting bottle 10 at the timing when the personal ID is transmitted from the personal ID transmitter of the medical worker who operated the nozzle head. On the other hand, there is a possibility that another medical worker is moving near the disinfection bottle and the personal ID transmitted from the personal ID transmitter of the other medical worker is received by the hand-washing management device. As a result, when a plurality of personal IDs are received by the hand-washing management device, if an attempt is made to identify the user of the disinfecting bottle based on the received electric field strength, it may not always be possible to identify the correct user. There was a problem.

The present invention has been made to solve such a problem, and even in a system configured to intermittently transmit a signal from a transmission device carried by a medical worker, any medical treatment is performed. The purpose is to be able to pinpoint which healthcare worker performed hand hygiene when it was performed by the worker.

In order to solve the above-mentioned problems, the hand hygiene behavior detection system of the present invention is equipped with a discharge operation detection device that detects that a discharge operation has been performed on the disinfectant container and transmits operation execution information together with the detection device ID. Install disinfectant containers at various locations in the facility. In addition, the operation execution information and the detection device ID transmitted from the discharge operation detection device and the medical worker ID periodically transmitted at predetermined intervals from the wireless transmission device carried by the medical worker are asynchronous with each other. The relay device that receives in the form and transmits it to the management device together with the relay device ID is installed in a plurality of places including the place defined as the same space as each place where the disinfection container is installed and the other places. The management device identifies the relay device in the same space as the discharge operation detection device indicated by the detection device ID received from the relay device at a certain time, and then within a predetermined period based on the time when the detection device ID is received. For the medical staff ID received in, the location where the medical staff exists is estimated on the layout of the facility indicated by the information acquired by the database information acquisition unit, and the estimated location is indicated by the detection device ID. Identify the healthcare professional who is in the same space as the discharge operation detector. Further, the management device determines whether or not there are multiple medical workers in the same space identified in this way, and if it is determined that there is only one medical worker, the medical worker who has performed hand hygiene is assigned to the medical worker. Identify as. On the other hand, when it is determined that there are a plurality of medical staff in the same space, the medical staff who is assumed to be in the vicinity of the discharge operation detection device indicated by the detection device ID received at a certain time is specified. By doing so, the medical staff in the vicinity is identified as the medical staff who performed hand hygiene.

According to the present invention configured as described above, the layout of the facility is intended for the medical staff corresponding to the medical worker ID received within a predetermined period based on the time when the management device receives the detection device ID. The location where the health care worker is located is estimated above, and the health care worker whose estimated location is in the same space as the discharge operation detection device is identified, and the health care worker in the same space is hand-sanitized. Can be identified as the healthcare professional who performed the. As a result, even in the hand hygiene behavior detection system configured so that the medical worker ID is intermittently transmitted from the wireless transmission device carried by the medical worker, it is possible to identify the medical worker who has performed hand hygiene. it can.

Further, according to the present invention, even if there are a plurality of medical workers in the same space specified as described above, a medical worker who is assumed to be in the vicinity of the discharge operation detection device can be used. It can be identified and the health care worker in the vicinity can be identified as the health care worker who performed hand hygiene. As a result, when hand hygiene is performed by one medical worker by ejecting the disinfectant container, the disinfectant container is actually ejected even if another medical worker is present near the disinfectant container. The health care worker who performed the operation can be identified as the health care worker who performed hand hygiene.

As described above, according to the present invention, even in a system configured to intermittently transmit a signal from a transmission device carried by a medical worker, when hand hygiene is performed by any medical worker. , It is possible to pinpoint exactly which healthcare professional did it.

It is a figure which shows an example of each apparatus provided in the hand hygiene behavior detection system by this embodiment, and the place where they installed. It is a block diagram which shows the functional structure example of the management apparatus by this Embodiment. It is a figure which shows an example of the received information stored in the received information storage part of this embodiment. It is a figure for demonstrating the operation of the relay device identification part, the neighborhood existence person identification part, and the space existence person identification part by this Embodiment. It is a figure for demonstrating the predetermined period set with respect to the time point which the relay device received the detection device ID. It is a flowchart which shows the operation example of the management apparatus by this Embodiment.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an example of each device included in the hand hygiene behavior detection system according to the present embodiment and an installation location thereof. In the following embodiment, the facility to which the hand hygiene behavior detection system is applied is described as a hospital, but it can be applied to any facility such as a long-term care facility where the enforcement of hand hygiene is recommended. Is.

As shown in FIG. 1, the hand hygiene behavior detection system according to the present embodiment is a disinfectant bottle 10 that discharges a disinfectant (corresponding to a disinfectant container within the scope of claims. In FIG. 1, it is simply referred to as "bo". The discharge operation detection device 100 provided in (the), the wireless transmission device 200 carried by a medical worker, and the relay device 300 installed at each location in the hospital (simply "middle" in FIG. 1). ) And a management device 400 connected to the relay device 300 via a communication network.

Note that FIG. 1 shows a configuration in which the relay device 300 and the management device 400 are connected by a wired communication network (for example, a wired LAN), but the present invention is not limited to this. For example, the relay device 300 and the access point may be connected by a wireless LAN such as Wi-Fi (registered trademark), and the access point and the management device 400 may be connected by a wired LAN.

As shown in FIG. 1, the disinfecting bottle 10 is installed in, for example, each hospital room R1, R2, R3 in the hospital. The position in the hospital room R1, R2, R3 where the disinfection bottle 10 is installed is, for example, near the doorway. Alternatively, it may be located near the bed in the hospital room. The position where the disinfectant bottle 10 is installed may be a position outside the hospital room (corridor CR) near the entrance / exit of each hospital room R1, R2, R3.

As shown in FIG. 1, the disinfectant bottle 10 is a pump-type bottle, and a constant amount of the disinfectant liquid in the bottle is discharged by pressing the upper nozzle head downward. A discharge operation detection device 100 is attached to this nozzle head. The discharge operation detection device 100 includes a pressure-sensitive sensor, and detects that a discharge operation (nozzle head pressing operation) has been performed on the disinfecting bottle 10.

The discharge operation detection device 100 includes a wireless transmission circuit, and when the discharge operation for the disinfecting bottle 10 is detected by the pressure-sensitive sensor, the operation execution information indicating that the discharge operation has been executed is its own identification information. It is transmitted wirelessly together with the detection device ID. The detection device ID is identification information unique to the discharge operation detection device 100, and is stored in advance in the internal memory. The detection device ID transmitted by the discharge operation detection device 100 is received by the relay device 300 installed in the same space as the disinfection bottle 10.

The wireless transmission device 200 carried by the medical worker periodically transmits the medical worker ID, which is the identification information of the medical worker, at predetermined intervals. For example, the wireless transmitter 200 transmits a medical worker ID every 5 seconds. The medical worker ID is identification information unique to the medical worker, and is stored in advance in the internal memory of the wireless transmission device 200. The medical worker ID is transmitted at predetermined intervals in order to keep the power consumption of the built-in battery low and to enable the wireless transmission device 200 to be used continuously for as long as possible. The medical worker ID transmitted by the wireless transmission device 200 is received by the relay device 300 around the position where the medical worker is present.

The relay device 300 receives the operation execution information and the detection device ID from the discharge operation detection device 100 of the disinfection bottle 10, and also receives the medical worker ID from the wireless transmission device 200 in a form asynchronous with this reception to communicate. The received information is transmitted to the management device 400 connected via the network together with the relay device ID which is its own identification information. The relay device ID is identification information unique to the relay device 300 and is stored in advance in the internal memory.

The asynchronous form means that the timing of receiving the operation execution information and the detection device ID from the discharge operation detection device 100 and the timing of receiving the medical worker ID from the wireless transmission device 200 do not always match. .. That is, the operation execution information and the detection device ID are transmitted when the discharge operation detection device 100 detects the discharge operation, whereas the medical worker ID has a predetermined time interval (independent of the detection of the discharge operation). Since it is transmitted periodically (every 5 seconds), the timing of receiving this information by the relay device 300 is asynchronous.

The relay device 300 is installed in a plurality of places including a place defined as the same space as each place where the disinfection bottle 10 is installed and a place other than the place where the disinfection bottle 10 is installed. In the example of FIG. 1, the disinfectant bottle 10 is installed in each hospital room R1, R2, R3 in the hospital. In this case, the place defined as the same space as each place where the disinfection bottle 10 is installed means each hospital room R1, R2, R3. Further, the other place means a place other than the hospital room, and in the example of FIG. 1, it is a corridor CR.

When the disinfectant bottle 10 is installed outside the hospital room (corridor CR) near the entrance / exit of the hospital room, the place defined as the same space as the place where the disinfectant bottle 10 is installed is not the corridor CR. It is a hospital room having an entrance / exit closest to the disinfection bottle 10. As will be described later, definition information is stored in a first database provided in the management device 400 as to which hospital room has the same space as the place where the disinfection bottle 10 is installed. Depending on the installation location of the disinfection bottle 10, the same space as the location where the disinfection bottle 10 is installed may be defined as a part of the corridor.

The management device 400 identifies a medical worker who has performed hand hygiene through a discharge operation on the disinfecting bottle 10 based on the operation execution information, the detection device ID, the medical worker ID, and the relay device ID transmitted from the relay device 300. Perform the processing to be performed. The details of this process will be described with reference to FIG. 2 below.

FIG. 2 is a block diagram showing a functional configuration example of the management device 400. As shown in FIG. 2, the management device 400 has a first database storage unit 401 (denoted as a first DB storage unit in FIG. 2) and a second database storage unit 402 (second in FIG. 2) as storage media. It is provided with a DB storage unit), a reception information storage unit 403, and a hand hygiene management information storage unit 404. Further, the management device 400 has a communication unit 41, a first database information acquisition unit 42 (denoted as the first DB information acquisition unit in FIG. 2), a relay device identification unit 43, and a space existence identification unit as functional configurations. 44, neighborhood presence identification unit 45, second database information acquisition unit 46 (denoted as second DB information acquisition unit in FIG. 2), portable non-possessed person identification unit 47, implementation medical worker identification unit 48 and information. A recording unit 49 is provided.

Each of the above functional blocks 41 to 49 can be configured by any of hardware, DSP (Digital Signal Processor), and software. For example, when configured by software, each of the functional blocks 41 to 49 is actually configured to include a computer CPU, RAM, ROM, etc., and is realized by operating a program stored in the RAM or ROM. The program may be stored in another recording medium such as a hard disk or a semiconductor memory.

The first database storage unit 401 includes facility layout information including definition information of the space, and installation location information indicating the installation locations of the discharge operation detection device 100 and the relay device 300 on the layout of the facility indicated by the layout information. The first database (corresponding to the database of claims) including and is stored in advance. The facility layout information is information including the position and shape (including size) of each hospital room R1, R2, R3, and the position and shape (including size) of the corridor CR. The installation location information is information indicating which hospital room R1, R2, R3 or which corridor CR each of the discharge operation detection device 100 and the relay device 300 is installed at, and is described in the discharge operation detection device 100, which will be described later. The installation location is shown in association with the detection device ID and the relay device ID of the relay device 300. The first database also includes definitional information indicating which location (hospital room R1, R2, R3 or corridor CR) is the same space for each of the disinfectant bottles 10.

The second database storage unit 402 stores in advance a second database including possession information indicating whether or not the medical staff possesses a portable disinfection container (hereinafter referred to as a portable disinfection bottle). .. The disinfectant bottle 10 shown in FIG. 1 is used by being installed in the fixed place shown in FIG. 1, whereas it is a type of mobile phone that is carried and used by a medical worker separately. There are also mold disinfectant bottles (not shown). The portable disinfection bottle is also provided with a discharge operation detection device for detecting the discharge operation, and the operation execution information is wirelessly transmitted together with the bottle ID in response to the detection of the discharge operation. The bottle ID is identification information unique to the portable disinfectant bottle, and is stored in advance in the internal memory of the discharge operation detection device.

The second database storage unit 402 stores a second database formed by associating a medical worker ID of a medical worker with a bottle ID of a portable disinfecting bottle assigned to the medical worker. Yes, the medical staff whose medical worker ID is stored in this second database has a portable disinfectant bottle, and the medical staff whose medical worker ID is not stored in the second database Indicates that you do not have a portable disinfectant bottle. The second database may store the medical worker IDs of all medical workers in association with the flag information indicating whether or not they have a portable disinfectant bottle.

The communication unit 41 receives the operation execution information, the detection device ID, the medical worker ID, and the relay device ID transmitted from the relay device 300. Specifically, the communication unit 41 adds the operation execution information and the detection device ID transmitted from the discharge operation detection device 100 when the discharge operation detection device 100 of the disinfection bottle 10 detects the discharge operation, and the relay device 300. Receives the relay device ID. Further, the communication unit 41 receives the medical worker ID periodically transmitted from the wireless transmission device 200 of the medical worker and the relay device ID added by the relay device 300.

Each time the communication unit 41 receives information from the relay device 300, the communication unit 41 stores the received information in the reception information storage unit 403 in chronological order. FIG. 3 is a diagram showing an example of received information stored in the received information storage unit 403. The reception information storage unit 403 stores one reception information in one record. One record includes a record ID, a reception time, a relay device ID, an operation execution information, a detection device ID, a medical worker ID, and a bottle ID as items.

When the communication unit 41 receives the operation execution information, the detection device ID, and the relay device ID from the relay device 300, one record is added to the reception information storage unit 403, and the record ID, reception time, and relay are added to the added record. The device ID, operation execution information, and detection device ID are recorded (record ID = R6). No medical worker ID and bottle ID are recorded in this record. As described above, the received information of the record R6 is the information transmitted from the discharge operation detection device 100 via the relay device 300 when the discharge operation detection device 100 of the disinfection bottle 10 detects the discharge operation. ..

When the communication unit 41 receives the medical worker ID and the relay device ID from the relay device 300, one record is added to the reception information storage unit 403, and the record ID, reception time, and relay device are added to the added record. The ID and the medical worker ID are recorded (record ID = R1 to R5, R7, R100). The operation execution information, the detection device ID, and the bottle ID are not recorded in these records. As described above, the received information of these records R1 to R5, R7, and R100 is information periodically transmitted from the wireless transmission device 200 of the medical staff via the relay device 300.

Here, the received information of the records R2 to R4 is the same medical worker ID received from three different relay devices 300 at the same time. This is because there are three relay devices 300 around the medical worker indicated by the medical worker ID (the range in which the radio wave of the wireless transmission device 200 can reach), and the medical worker ID transmitted from the wireless transmission device 200 is used. It is shown that the three relay devices 300 are received at almost the same time, and the same medical worker ID is transmitted from each relay device 300 together with the respective relay device IDs.

Further, the received information of the record R1 and the received information of the record R100 have the same medical worker ID. This indicates that it is the received information for two times that is periodically transmitted from the wireless transmission device 200 of the medical staff at a predetermined interval (5 seconds). In the example of FIG. 3, the relay device ID included in the reception information of the record R1 and the relay device ID included in the reception information of the record R100 are the same. This means that the healthcare professional remains close to the same relay device 300 for 5 seconds. If the healthcare professional moves closer to another relay device 300 within 5 seconds, the recorded relay device ID will be different.

When the communication unit 41 receives the operation execution information, the bottle ID, and the relay device ID from the relay device 300, one record is added to the reception information storage unit 403, and the record ID, reception time, and the like are added to the added record. The relay device ID, operation execution information, and bottle ID are recorded (not shown). The detection device ID and the medical worker ID are not recorded in this record.

The first database information acquisition unit 42 (corresponding to the database information acquisition unit within the scope of claims) acquires layout information and installation location information from the first database stored in the first database storage unit 401.

The relay device identification unit 43 is in the same space as the discharge operation detection device 100 indicated by the detection device ID received from the relay device 300 at a certain time based on the information acquired by the first database information acquisition unit 42. The relay device 300 is specified. The detection device ID received from the relay device 300 at a certain point in time is, in the example of FIG. 3, the detection device ID included in the reception information recorded in the record R6. That is, it is the detection device ID transmitted from the discharge operation detection device 100 via the relay device 300 when the discharge operation is detected by the discharge operation detection device 100 indicated by the detection device ID.

The installation location of the discharge operation detection device 100 (that is, the discharge operation detection device 100 in which the discharge operation has been performed) corresponding to the detection device ID is the layout information and the installation location information acquired by the first database information acquisition unit 42. It is possible to identify based on. Further, the layout information and the installation location information also include information on the relay device 300 installed in the same space as the discharge operation detection device 100. Thereby, the relay device specifying unit 43 can specify the relay device 300 in the same space as the discharge operation detection device 100 in which the discharge operation is performed.

The method for specifying the relay device 300 in the same space as the discharge operation detection device 100 on which the discharge operation is performed is not limited to this. For example, the relay device 300 corresponding to the relay device ID included in the received information of the record R6 together with the detection device ID is set as the relay device 300 in the same space as the discharge operation detection device 100 in which the discharge operation is performed. It may be specified.

FIG. 4 is a diagram for explaining the operation of the relay device specifying unit 43. Note that FIG. 4 is also used when explaining the operations of the space presence identification unit 44 and the neighborhood existence identification unit 45, which will be described later.

FIG. 4A shows a state in which a medical worker is present in the hospital room R1. Here, after the detection device ID is transmitted to the relay device 300 in the hospital room R1 by the medical worker A operating the disinfection bottle 10 in the hospital room R1, the medical worker A walks slightly in the same hospital room R1. It shows a state in which the medical worker ID is transmitted from the wireless transmission device 200 to the relay device 300 in the hospital room R1 when the patient moves. In this case, the relay device specifying unit 43 makes the relay device 300 in the hospital room R1 the same as the discharge operation detection device 100 indicated by the detection device ID received from the relay device 300 at the time when the discharge operation detection device 100 is discharged. It is specified as a relay device 300 in the space.

FIG. 4 (b) shows the medical staff A in the same state as in FIG. 4 (a), and when another medical worker B walking in the corridor CR approaches the entrance / exit of the hospital room R1. The state in which the medical worker ID is also transmitted from the wireless transmission device 200 of the worker B is shown. In the example of FIG. 4B, the medical worker ID transmitted from the wireless transmission device 200 of the medical worker B in the corridor CR is the hospital room in addition to the two relay devices 300 installed in the corridor CR. It is also received by the relay device 300 in R1. In this case, as in records R2 to R4 of FIG. 3, three received information including the same medical worker ID is stored in the received information storage unit 403 at the same time.

In the state shown in FIG. 4B, as in the case of FIG. 4A, the relay device specifying unit 43 relays the relay device 300 in the hospital room R1 when the discharge operation detection device 100 is discharged. It is specified as a relay device 300 in the same space as the discharge operation detection device 100 indicated by the detection device ID received from the 300. This is because the relay device 300 still receives the detection device ID from the discharge operation detection device 100 and transmits the detection device ID together with the relay device ID to the management device 400.

The space presence identification unit 44 targets the medical worker ID received within a predetermined period based on the time when the detection device ID is received by the relay device 300 specified by the relay device identification unit 43. Obtained by the first database information acquisition unit 42 based on one or more relay device IDs received together with the medical worker ID from one or more relay devices 300 including the relay device 300 specified by the specific unit 43. Estimate where the healthcare staff is on the layout of the facility indicated by the information. Then, the medical worker whose estimated location is in the same space as the discharge operation detection device 100 indicated by the detection device ID is specified.

FIG. 5 is a diagram for explaining a predetermined period set with reference to the time when the relay device receives the detection device ID. FIG. 5 shows the time axis of the timing at which the medical worker ID is periodically transmitted from the wireless transmission device 200 carried by the three medical workers A to C and the timing at which the communication unit 41 receives the detection device ID. It is schematically shown by the straight line of. Timing T _D of the communication unit 41 receives the detection device ID is a time when the discharge operation of the discharge operation detection device 100 is detected, corresponding to the timing of the received information is recorded in the record R6 say in the example of FIG. 3 To do.

In the example of FIG. 5, the range of −Δ _t time earlier and + Δ _{t time later than the timing T D} when the communication unit 41 receives the detection device ID is set as a predetermined period. .. The predetermined period is set to be shorter than the time interval of the interval at which the wireless transmission device 200 transmits the medical worker ID. It is assumed that the space existence person identification unit 44 is in the same space as the discharge operation detection device 100 in which the discharge operation is performed for the medical worker corresponding to the medical worker ID received within this predetermined period. Identify the health care worker to be.

In FIG. 5, the medical practitioner A, B is received medical person ID within the predetermined time period based on the timing T _D of the communication unit 41 receives the detection device ID. Therefore, the space presence identification unit 44 identifies the medical worker who is assumed to be in the same space as the discharge operation detection device 100 which has been discharged from the medical workers A and B.

To explain with reference to FIG. 3, a timing T _D of the communication unit 41 receives the detection device ID is timing when the reception information is recorded in the record R6. The space existence identification unit 44 receives the record R6 within the predetermined period with the range _{of −Δ t} time earlier and + Δ _{t time later than the reception time of the record R6 as a predetermined period.} Records R2 and R7 in which the same relay device ID as the relay device ID of record R6 is recorded are extracted from the recorded records. Then, the medical staff corresponding to the medical worker IDs "S003" and "S026" included in the records R2 and R7 extracted in this way is extracted as a determination target of whether or not they are in the same space.

Here, with reference to the timing T _D of the communication unit 41 receives the detection device ID, but have set earlier to - [delta _t time and slow range of + delta _t time towards than a predetermined time period , to only a range of - [delta _t time earlier than the timing T _D may be set as the predetermined time period it may be only a range of slower to + delta _t time set as the predetermined time period .. In the former case, the processing of the space existence identification unit 44 can be performed immediately when the communication unit 41 receives the detection device ID. In this case, it was operated in a case where any medical worker operated the disinfecting bottle 10 after the medical worker ID was transmitted while the medical worker was approaching the disinfecting bottle 10. It is possible to identify a medical worker who is in the same space as the discharge operation detection device 100.

_{On the other hand, when the range of + Δt} time is also set as a predetermined period later than _{the timing T D} when the communication unit 41 receives the detection device ID, after any medical worker operates the disinfection bottle 10. , Even in the case where the medical worker ID is transmitted while the medical worker is moving away from the disinfecting bottle 10, it is possible to identify the medical worker who is in the same space as the operated discharge operation detection device 100. Is. _{In this case, it is necessary to wait for + Δt} time to elapse from the time when the communication unit 41 receives the detection device ID, and then perform the processing of the space presence identification unit 44. However, there is no problem waiting for _{+ Δt} time to elapse unless there is a special reason to immediately identify the person performing hand hygiene.

For example, as shown in FIG. 4A, when only one medical worker ID is received within a predetermined period in the relay device 300 specified by the relay device identification unit 43, that is, with respect to the relay device 300. When there is only one medical worker A within the range of the radio wave of the wireless transmitter 200, the space presence identification unit 44 targets the one medical worker A and is indicated by a detection device ID. A medical worker who is in the same space as the discharge operation detection device 100 (the discharge operation detection device 100 in which the discharge operation is detected) is specified. That is, it is determined whether or not the medical worker A is in the same space as the discharge operation detection device 100 in which the discharge operation is detected. In the case of FIG. 4A, the space presence identification unit 44 identifies the medical worker A as a medical worker who is in the same space as the operated discharge operation detection device 100.

Further, as shown in FIG. 4B, when a plurality of medical worker IDs are received within a predetermined period in the relay device 300 specified by the relay device identification unit 43, that is, wirelessly to the relay device 300. When two medical workers A and B are within the range of the radio wave of the transmitting device 200, the space presence identification unit 44 targets the two medical workers A and B with the detection device ID. A medical worker who is in the same space as the indicated discharge operation detection device 100 (discharge operation detection device 100 in which the discharge operation is detected) is specified. In the case of FIG. 4B, the space presence identification unit 44 identifies the medical worker A as a medical worker who is in the same space as the operated discharge operation detection device 100.

In this way, in identifying whether or not the medical worker is in the same space as the discharge operation detection device 100, it is necessary to estimate the location of the medical worker. Here, as in the case of the medical worker A shown in FIGS. 4A and 4B, when the medical worker ID is recorded in only one record at the same time, the space existence identification unit 44 records the record. The installation location of the relay device 300 corresponding to the relay device ID recorded together with the medical worker ID is specified based on the layout information and the installation location information acquired by the first database information acquisition unit 42. The installation location of the specified relay device 300 is estimated as the location of the medical staff. The relay device 300 specified in this way is specified by the relay device specifying unit 43 as being in the same space as the discharge operation detection device 100 in which the discharge operation is detected. Therefore, in this case, it can be said that the location of the medical worker A is in the same space as the discharge operation detection device 100 in which the discharge operation is detected.

On the other hand, when the same medical worker ID is recorded in a plurality of records at the same time as in the medical worker B shown in FIG. 4 (b), the space existence identification unit 44 is included in the plurality of records. The location of the medical staff is estimated from the installation locations of the plurality of relay devices 300 corresponding to the different relay device IDs recorded together with the same medical worker ID. For example, the space existence identification unit 44 calculates the position of the center of gravity of the installation location of the plurality of relay devices 300 based on the layout information acquired by the first database information acquisition unit 42 and the installation location. Then, the calculated position of the center of gravity is specified on the layout, and the specified position is estimated as the location of the medical staff.

In order to estimate the location of the medical worker, the received electric field strength when the plurality of relay devices 300 receive the medical worker ID from the wireless transmission device 200 may be used. For example, among the plurality of relay devices 300, the installation location of the relay device 300 having the largest received electric field strength may be estimated as the location of the medical staff. Alternatively, it is set based on the installation location of the three relay devices 300 and the three distances calculated from the received electric field strengths of the three relay devices 300 by a known three-point positioning method using the received electric field strength. The place where the three ranges intersect may be estimated as the place where the medical staff exists.

In this way, when the locations of the medical staff A and B are estimated in the state of FIG. 4B, the location of the medical staff A is the same space as the discharge operation detection device 100 in which the discharge operation is detected. While it is presumed to be inside, it is presumed that the location of the medical worker B is not in the same space as the discharge operation detection device 100 in which the discharge operation is detected. Therefore, the space presence identification unit 44 estimates among the two medical workers A and B for which the medical worker ID is received within a predetermined period in the relay device 300 specified by the relay device identification unit 43. The medical worker A whose location is in the same space as the discharge operation detection device 100 is specified.

When estimating the location of a medical worker using the received electric field strength of the relay device 300, the relay device 300 includes a circuit configuration for detecting the received electric field strength, and the medical worker ID and the relay device ID. At the same time, the detected received electric field strength information is also transmitted to the management device 400. The management device 400 also stores the received received electric field strength information in the reception information storage unit 403 as one item of the record. The space presence identification unit 44 estimates the location of the medical staff by using the information of the reception electric field strength stored in the reception information storage unit 403.

The neighborhood presence identification unit 45 determines whether or not there are a plurality of medical staff in the same space specified by the space presence identification unit 44, and if there are a plurality of medical staff, among the plurality of medical staff. At a certain point in time, a medical worker who is assumed to be in the vicinity of the discharge operation detection device 100 indicated by the received detection device ID is specified.

For example, the relay device 300 specifies the relative position of the wireless transmission device 200 from the relay device 300 based on the received radio wave intensity when the medical worker ID is received from the wireless transmission device 200. Then, the relay device 300 transmits the relative position information of the specified wireless transmission device 200 to the management device 400 together with the medical worker ID and the relay device ID. The management device 400 stores the sent information in the reception information storage unit 403. The neighborhood presence identification unit 45 estimates the location of the medical staff by using the relative position information of the wireless transmission device 200 stored in the reception information storage unit 403, and determines the location of the estimated medical staff. It is assumed that a medical worker whose distance to the discharge operation detection device 100 is equal to or less than a predetermined value is in a place (near place) within a predetermined range from the discharge operation detection device 100 indicated by the detection device ID received at a certain time. Identify as a healthcare professional. The relay device 300 identifies the relative direction of the wireless transmission device 200 by using a known technique of detecting the direction in which the radio wave arrives by the AoA (Angle of Arrival) method, and reaches the radio wave transmission source based on the received radio wave strength. By specifying the relative distance to the radio wave transmitting device 200 by using a known technique for detecting the distance of the radio wave transmitting device 200, it is possible to specify the relative position of the radio wave transmitting device 200 from the relay device 300.

When processing the space presence identification unit 44, the location of the medical staff is estimated by using the relative position information of the radio transmission device 200 specified by the relay device 300 as described above. Based on the estimated location of the medical worker, the medical worker who is assumed to be in the same space as the discharge operation detection device 100 in which the discharge operation is detected may be specified.

In the case of the example shown in FIG. 4B, since only the medical worker A is in the same space as the discharge operation detection device 100 indicated by the detection device ID received at a certain time, the neighborhood presence identification unit. The process of 45 is not executed. If it is specified by the space presence identification unit 44 that a medical worker X other than the medical worker A also exists in the hospital room R1, the processing of the neighborhood presence identification unit 45 is executed. From the medical workers A and X, a medical worker who is assumed to be in the vicinity of a predetermined distance from the discharge operation detection device 100 in which the discharge operation of the disinfection bottle 10 is detected is specified.

The second database information acquisition unit 46 acquires possession information from the second database. The portable non-owner identification unit 47 determines whether or not there are a plurality of nearby medical workers identified by the neighborhood presence identification unit 45, and if there are a plurality of medical workers, the second database information acquisition unit 46 acquires the number. Based on the information provided, identify healthcare professionals who do not have a portable disinfectant bottle. That is, the portable non-owner identification unit 47 is the first of the medical worker IDs corresponding to a plurality of medical workers identified as being in the vicinity of the discharge operation detection device 100 by the nearby presence identification unit 45. A medical worker corresponding to a medical worker ID different from the medical worker ID stored in the database of 2 is specified as a medical worker who does not have a portable disinfectant bottle.

When there is only one medical worker in the same space specified by the space existing person identification unit 44, the implementing medical worker identification unit 48 performs hand hygiene on the medical worker in the same space. Identify as a worker. In addition, the implementation medical worker identification unit 48 is a case where there are a plurality of medical workers in the same space specified by the space existence person identification unit 44, and the vicinity specified by the neighborhood presence person identification unit 45. If there is only one health care worker in the vicinity, the health care worker in the vicinity is identified as the health care worker who performed hand hygiene.

In addition, the implementation medical worker identification unit 48 is a case where there are a plurality of medical workers in the same space specified by the space existence person identification unit 44, and the vicinity specified by the neighborhood presence person identification unit 45. When there are a plurality of medical staff in the above, the medical worker specified by the portable non-possessed person identification unit 47 is specified as a medical worker who has performed hand hygiene.

The information recording unit 49 stores the medical worker specified as the performer of hand hygiene by the implementing medical worker identification unit 48 in the hand hygiene management information storage unit 404 as history information together with information on the execution time and execution place. That is, the information recording unit 49 corresponds to the detection device ID in the record R6 in which the detection device ID of the discharge operation detection device 100 in which the discharge operation is detected is recorded, with the reception time as the execution time of hand hygiene. One record is composed together with the medical worker ID of the medical worker specified as the performer of hand hygiene by the implementing medical worker identification unit 48, with the installation location of the discharge operation detection device 100 as the execution place of hand hygiene. Information is stored in the hand hygiene management information storage unit 404.

When the communication unit 41 receives the information including the bottle ID from the relay device 300, the information recording unit 49 performs medical treatment corresponding to the bottle ID based on the information acquired by the second database information acquisition unit 46. The worker ID is specified, and one record is composed including the specified medical worker ID, the reception time (execution time of hand hygiene) included in the record in which the reception information is recorded, and the bottle ID. The record information is stored in the hand hygiene management information storage unit 404.

FIG. 6 is a flowchart showing an operation example of the management device 400 according to the present embodiment configured as described above. The management device 400 constantly and repeatedly executes the processing of the flowchart shown in FIG. In FIG. 6, the operation when the management device 400 receives the bottle ID is omitted.

First, the communication unit 41 determines whether or not information has been received from the relay device 300 (step S1). If no information has been received from the relay device 300 (step S1: No), the determination in step S1 is repeated. On the other hand, when the communication unit 41 receives the information (step S1: Yes), the reception information storage unit 403 adds one record and stores the information received by the communication unit 41 (step S2).

Next, the relay device identification unit 43 determines whether or not the detection device ID of the discharge operation detection device 100 is included in the reception information stored in the reception information storage unit 403 (step S3). That is, here, it is determined whether or not the discharge operation is detected by any of the discharge operation detection devices 100. When the detection device ID is not included in the received information (step S3: No), it corresponds to the case where the medical worker ID periodically transmitted from the wireless transmission device 200 is received. Instead, the process returns to step S1.

On the other hand, when the detection device ID is included in the received information (step S3: Yes), the relay device identification unit 43 uses the relay device ID included in the reception information and the first database information acquisition unit 42. Based on the information acquired from the first database storage unit 401, the relay device 300 in the same space as the discharge operation detection device 100 indicated by the detection device ID is specified (step S4).

Next, the space presence identification unit 44 is targeted by the relay device identification unit 43 for the medical worker ID received within a predetermined period based on the time when the communication unit 41 receives the detection device ID in step S1. It is indicated by the information acquired by the first database information acquisition unit 42 based on the one or more relay device IDs received together with the medical worker ID from one or more relay devices 300 including the specified relay device 300. The location where the medical staff is located is estimated on the layout of the facility, and the medical staff whose estimated location is in the same space as the discharge operation detection device 100 indicated by the detection device ID is specified (step S5). .. _{When the communication unit 41 sets a predetermined period including the range of + Δ t} time later than the time when the detection device ID is received in step S1, the communication unit 41 receives the detection device ID. _{Waiting for + Δt} time to elapse from the time point (while executing the processing of steps S1 to S3), the processing of the space existence identification unit 44 is performed.

Here, the neighborhood presence identification unit 45 determines whether or not there are a plurality of medical workers in the same space specified by the space presence identification unit 44 (step S6). When it is determined that there are not a plurality of medical staff in the same space (step S6: No), that is, when there is one medical worker in the same space, the implementation medical worker identification unit 48 is a person who exists in the same space. The medical worker specified by the specific unit 44 is specified as a medical worker who has performed hand hygiene (step S7). After that, the process proceeds to step S13.

On the other hand, when it is determined by the neighborhood presence identification unit 45 that there are a plurality of medical staff in the same space (step S6: Yes), the neighborhood presence identification unit 45 is selected from among the plurality of medical staff. A medical worker who is assumed to be in the vicinity of a predetermined distance from the discharge operation detection device 100 whose discharge operation has been inspected is specified (step S8).

Further, the portable non-owner identification unit 47 determines whether or not there are a plurality of nearby medical workers identified by the neighborhood presence identification unit 45 (step S9). Here, when it is determined that there are not a plurality of nearby medical workers (step S9: No), the implementing medical worker identification unit 48 points to the nearby medical workers specified by the nearby presence identification unit 45. Identify as a health care worker who has performed hygiene (step S10). After that, the process proceeds to step S13.

On the other hand, when it is determined that there are a plurality of medical workers in the vicinity (step S9: Yes), the portable non-owner identification unit 47 is based on the information acquired by the second database information acquisition unit 46. Identify a healthcare professional who does not have a portable disinfectant bottle (step S11). In this case, the implementing medical worker identification unit 48 identifies the medical worker specified by the portable non-possessed person identification unit 47 as a medical worker who has performed hand hygiene (step S12). After that, the process proceeds to step S13.

In step S13, the information recording unit 49 uses the medical worker specified as the performer of hand hygiene by the medical worker identification unit 48 in steps S7, S10 or S12 as history information together with information on the execution time and execution location. It is stored in the hand hygiene management information storage unit 404. As a result, one process of the flowchart shown in FIG. 6 is completed.

As described in detail above, according to the present embodiment, the target is a medical worker corresponding to the medical worker ID received within a predetermined period based on the time when the management device 400 receives the detection device ID. The location where the medical staff is located is estimated on the layout of the facility, and the medical staff whose estimated location is in the same space as the discharge operation detection device 100 is specified, and the medical staff in the same space is identified. A person can be identified as a health care worker who has performed hand hygiene. As a result, even in the hand hygiene behavior detection system configured so that the medical worker ID is intermittently transmitted from the wireless transmission device 200 carried by the medical worker, the medical worker who has performed hand hygiene can be identified. Can be done.

Further, according to the present embodiment, even if there are a plurality of medical workers in the same space specified as described above, it is assumed that the medical workers are in the vicinity of the discharge operation detection device 100. A person can be identified and a health care worker in the vicinity can be identified as a health care worker who has performed hand hygiene. As a result, when hand hygiene is performed by a medical worker by ejecting the disinfecting bottle 10, even if another medical worker is present near the disinfecting bottle 10, the disinfecting bottle is actually used. The medical worker who performed the discharge operation of 10 can be identified as the medical worker who performed hand hygiene.

Further, according to the present embodiment, even when there are a plurality of medical workers existing in the vicinity specified as described above, based on the information acquired by the second database information acquisition unit 46. , A health care worker who does not have a portable disinfectant bottle can be identified, and the health care worker can be identified as a health care worker who has performed hand hygiene. This is because it is considered that a medical worker who has a portable disinfectant bottle operates the portable disinfectant bottle he / she owns instead of the disinfectant bottle 10 installed in a fixed place. .. As a result, when hand hygiene is performed by a medical worker by ejecting the disinfecting bottle 10, even if another medical worker is present in the vicinity of the disinfecting bottle 10, the disinfecting bottle is actually used. The medical worker who performed the discharge operation of 10 can be identified as the medical worker who performed hand hygiene.

As described above, according to the present embodiment, hand hygiene is performed by any medical worker even in a system configured to intermittently transmit a signal from the wireless transmission device 200 carried by the medical worker. At that time, it is possible to pinpoint exactly which healthcare professional did it.

In the above embodiment, the location of the medical staff estimated by the neighborhood presence identification unit 45 based on the relative position information with the wireless transmission device 200 specified by the relay device 300 is determined by the discharge operation detection device 100. An example has been shown in which a medical worker within a distance is specified as a medical worker in the vicinity of the discharge operation detection device 100, but the present invention is not limited thereto.

For example, with respect to a certain health care workers, and the installation location of the repeater 300 to the communication unit 41 corresponds to the relay apparatus ID received together with the medical personnel ID immediately before the timing T _D which has received the detection device ID, immediately after the timing T _D Based on the installation location of the relay device 300 corresponding to the relay device ID received together with the medical worker ID, the locus of movement of the medical worker during one interval in which the medical worker ID is transmitted is obtained. This movement locus is generated, for example, by connecting the installation locations of the two relay devices 300 with a straight line. Then, when at least a part of the movement locus is present at a place within a predetermined distance from the installation place of the discharge operation detection device 100 in which the discharge operation is detected, the medical worker related to the movement locus is referred to the discharge operation detection device 100. It may be identified as a healthcare professional in the vicinity of.

In addition, the above embodiments are merely examples of embodiment of the present invention, and the technical scope of the present invention should not be construed in a limited manner. That is, the present invention can be practiced in various ways without departing from its spirit or its main features.
