Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. The following embodiment is an example in which the patient condition determination device of the present invention is applied, and it goes without saying that the content of the invention is not limited to the present embodiment.

[1. Whole system]
First, the entire system in this embodiment will be described. FIG. 1 is a diagram for explaining the entire patient state display system 1 incorporating the patient state determination device.

First, patient P is lying on a mattress 5 placed on the bed 3. The bed is provided with a state detection device 20.

The state detection device 20 is a device capable of continuously acquiring biological information of a patient, for example, acquiring values such as a patient's weight, body movement, blood pressure, and blood glucose level. As an example of the state detection device 20, for example, as shown in FIG. 1, the state may be detected between the bed 3 and the mattress 5, or the state may be detected by providing the sensor on the patient. Further, it may be configured to be provided directly on the bed device (for example, by utilizing the load related to the actuator). The state detection device 20 is connected to the patient state display device 10.

The patient state display device 10 has a function of a patient state determination device, and is connected to a state detection device 20, a measurement device 60, or another server device via a network. It has been done. Further, by holding the authentication card 65 over the patient status display device 10, the authentication process (login process) can be realized.

Login is performed by a person who has authority such as staff (nurse, doctor, long-term care staff). By logging in, you can check biometric information values, alarm details, and register in electronic medical records. Further, it may be possible to set the authority for each logged-in person and change the range in which the operation can be performed.

For example, the server 30, the electronic medical record server 40, the terminal device 50, and the mobile terminal device 55 are connected to the network.

The server 30 is a server that provides various services, and may be connected to a LAN in a hospital or facility, or may be provided externally via the Internet.

The electronic medical record server 40 is a server that stores electronic medical record information about the patient. Normally, it is connected to a network in a hospital or facility, but an external cloud server may be used, for example.

The terminal device 50 is a terminal device for connecting in a nurse station or a management room, and can grasp the state of the patient status display device 10 even if it is away. Further, the mobile terminal device 55 can be wirelessly connected to a LAN, for example, so that a nurse, an assistance staff, or the like can easily check the information of the patient status display device 10.

The patient status display device 10 will be described in detail with reference to FIG. The patient status display device 10 includes a display terminal 1000 and a connection device 2000. The display terminal 1000 is, for example, a tablet-type display terminal, which displays various information and accepts input of various operations. The display terminal 1000 may be a dedicated terminal constituting the patient status display device 10, or may be realized by installing an application (program) on a general-purpose tablet terminal.

The connection device 2000 is a device for connecting the display terminal 1000 and various devices. That is, it plays a role of a hub for various devices. For example, as shown in FIG. 1, by connecting to the state detection device 20, it is possible to continuously acquire the biometric information of the patient, and receive the biometric information from the measuring device 60 (for example, a thermometer). It is also possible to receive biometric information from a device worn by the patient (for example, a wristwatch-type wearable measuring device). Further, by connecting the authentication card 65 to, for example, the communication unit 220, an authentication process (for example, patient authentication or staff authentication) can be realized. As an authentication method, NFC is used as an example of short-range wireless communication in the present embodiment, but it is also possible to authenticate using another method such as a barcode, infrared rays, or an IC tag. good.

Further, a notification unit 260 is provided, and it is possible to notify when an error occurs, for example. Further, it can be connected to a server device or the like via a LAN (the LAN may be a wired LAN or a wireless LAN). The notification unit 260 may be configured to be invisible normally and to be lit (displayed) only when a notification is made. Further, instead of the display, for example, a sound such as an alarm sound, a warning sound, or a voice may be used for notification, or a light may be used for notification.

In the present embodiment, the display terminal 1000 is described as being used by being placed on the connecting device 2000, but the display terminal 1000 and the connecting device 2000 may be used separately. For example, the display terminal 1000 may be taken out and used in another place, or the connection device 2000 may be built in the bed device and the display terminal 1000 may be used separately.

[2. Functional configuration]
Subsequently, the functional configuration in the present embodiment will be described with reference to the drawings. FIG. 3 is a diagram for explaining the functional configuration of the display terminal 1000 and the connection device 2000 in the patient status display device 10.

[2.1 Display terminal]
First, the functional configuration of the display terminal 1000 will be described. The display terminal 1000 includes a control unit 100, a storage unit 110, a device communication unit 150, an operation unit 160, a display unit 170, and a LAN communication unit 180.

The control unit 100 is a functional unit for controlling the entire display terminal 1000. The control unit 100 realizes various functions by reading and executing various programs stored in the storage unit 110, and is configured by, for example, a CPU (Central Process Unit) or the like.

The storage unit 110 is a functional unit that stores various programs and various data necessary for the operation of the display terminal 1000. The storage unit 110 is composed of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

Further, the storage unit 110 stores the biological information 112, the individual electronic medical record data 120, and the alarm threshold table 122, and includes the main program 132, the alarm program 134, and the patient status display program 136 as programs. , The electronic medical record registration program 138 is stored.

The biological information 112 stores continuous biological information 114, which is biological information continuously detected by the state detection device 20, and measurement biological information 116 received from the measuring device 60 at an arbitrary timing. The measured biometric information can be manually input or a continuous biometric information value can be diverted as necessary.

Here, an example of the data structure of the continuous biological information 114 is shown in FIG. The continuous biological information 114 of the present embodiment stores the value of the biological information detected by the state detection device 20 and the value of the biological information whose state can be detected by another patient.

That is, it is stored based on a continuously detectable value. For example, the measurement date and time (for example, "2015/05/16 20:00"), the pulse rate (for example, "126"), and the body temperature (for example, "37.2") as values corresponding to the type of biometric information. ), Respiratory rate (eg, "15"), and SpO2 (eg, "99") are stored. That is, the continuous biological information 114 can acquire a predetermined measured value at any time. As a method of acquiring the continuous biological information 114, it may be acquired from the state detection device 20 or from the detection device provided on the bed 3. In addition, various sensors may be provided on the patient's body for acquisition.

Then, various acquired biometric information can be collectively managed as continuous biometric information. The items of these biological information values that are detected differ as needed (for example, when only the body motion detection sensor is used, the body motion state, sleep state, patient posture (getting out of bed, staying in bed, getting up), Pulse rate and respiratory rate are detected as continuous biometric information).

The measured biological information 116 stores biological information received from an external measuring device such as a thermometer, a sphygmomanometer, or a body fat scale. For example, as shown in FIG. 5, as the measurement biological information 116 of the present embodiment, for each reception date and time (for example, “2015/05/16 20:00”) and for each type of biological information (for example, “body temperature”). , The value (for example, "37.2") is stored. Further, for example, the systolic blood pressure (for example, "159") and the diastolic blood pressure (for example, "98") are stored.

Further, the detected continuous biological information 114 and the measured biological information 116 may be stored for a predetermined period of time. As the storage period, for example, data for one day or three days is stored. Further, the continuous biological information 114 and the measured biological information 116 may be stored in the server 30.

The individual electronic medical record data 120 stores the electronic medical record data of the individual patient. A collection of electronic medical record data of the individual patient is stored in the electronic medical record server 40. Since the data structure of the individual electronic medical record data 120 is the same as that stored in the electronic medical record server 40, the details will be described later. That is, in addition to the patient information, continuous biological information at the time of registration, measured biological information, and the like are registered.

In this embodiment, it is assumed that the data is stored in the storage unit 110, but the data of the electronic medical record server 40 may be directly used. In this case, the individual electronic medical record data 120 does not have to be stored in the storage unit 110.

The alarm threshold table 122 stores alarm thresholds for various biometric information values. When the measured (received) biological information value exceeds the alarm threshold value, notification is executed or error processing is performed. This alarm threshold value may be set in advance or may be set arbitrarily.

FIG. 6 shows an example of the alarm threshold table 122. As shown in FIG. 6, alarm thresholds of an upper limit value and a lower limit value are stored for each biological information. Further, a plurality of alarm threshold values can be stored depending on the type of alarm. Further, in the present embodiment, the attention level and the warning level are stored in two stages according to the alarm threshold value.

For example, for "pulse" which is one of the biological information, the threshold value of the pulse rate (threshold value in the range of attention level and warning level) is stored as the biological information value. Then, as the upper limit threshold value, the attention level is stored as "110" and the warning level is stored as "130". Further, as the lower limit threshold value, the attention level is stored as "60" and the warning level is stored as "30".

For example, when the pulse rate is 130 or more or 30 or less, it can be determined that the pulse rate is included in the warning level range. Further, when the pulse rate is "110 or more and less than 130" or "greater than 30 and 60 or less", it can be determined that the pulse rate is included in the caution level range. It may be the case that the threshold value is exceeded (for example, the pulse rate in the warning level range is greater than 130 or less than 30).

In this embodiment, for convenience of explanation, the caution level and the warning level are described in two stages, but it goes without saying that a range higher than that may be set.

The patient state identification information 124 is information for storing the patient's state. The patient condition identification information, which will be described later, will be displayed using the patient condition identification information. In the present embodiment, patient state identification information (section patient state identification information) determined based on the biometric information of the patient in the section from logout to the present, and patient state identification determined based on the biometric information of the current patient. Information (currently patient status identification information) is stored.

Here, the "normal", "caution", and "warning" states are stored in the patient state identification information. Normal is when the patient's biometric information value is within the alarm threshold range (neither the attention level nor the warning level). Further, "attention" is a case where there is a biometric information value within the threshold range of the attention level among the biometric information values of the patient. Similarly, the "warning" is when there is a biometric information value of the patient that is within the threshold range of the warning level.

Further, in the present embodiment, the section patient state identification information is determined based on the biometric information value from the previous logout to the present, but for example, based on the biometric information value between the previous logout and the previous login. Another section patient status identification information may be further stored.

In the present embodiment, the patient state identification information changes if any one of the biometric information values is applicable, but the patient state when a plurality of biometric information values reach the caution level or the warning level. The identification information may be updated. Further, the patient state identification information may be stored not only for one but also for each biological information or for each predetermined group. For example, as a predetermined group, continuous biological information and measured biological information may be separated, and patient state identification information based on the state of each patient may be determined and stored.

Further, the program stored in the storage unit 110 can be read by the control unit 100 to realize various functions. Specifically, the main function reads and executes the main program 132, and the alarm function reads and executes the patient status display program 136, thereby displaying the patient status. The electronic medical record registration function is realized by reading and executing the electronic medical record registration program 138.

The device communication unit 150 is a functional unit for communicating with the device communication unit 250, which will be described later. In the present embodiment, for example, it is described that communication is performed by connecting with USB, but for example, it may be another general-purpose connection method, or it may be connected wirelessly (Bluetooth (registered trademark), wireless LAN, etc.). You may. Further, a dedicated connection interface may be provided for communication.

The operation unit 160 is a function unit that receives operation input from the user, and may be, for example, a software key realized by a touch panel or an input device such as a keyboard or a mouse. Further, voice input or the like may be used.

The display unit 170 is a functional unit that displays various information to the user and performs notification processing. For example, it is realized by a liquid crystal display or the like. Further, it may be realized by a touch panel in which the operation unit 160 and the display unit 170 are integrally formed.

The LAN communication unit 180 is an interface unit that can be connected to a LAN. It is composed of NIC and the like for connecting to Ethernet (registered trademark). The LAN communication unit 180 may be provided in the connection device 2000. In this case, the data to be transmitted is once sent to the connecting device 2000 via the device communication unit 150 (250) and then transmitted to the network. In order to connect to the LAN, it may be connected by wire or wirelessly.

[2.2 Connection device]
Next, the functional configuration of the connecting device 2000 will be described. The connection device 2000 includes a control unit 200, a storage unit 210, a communication unit 220, an interface unit 230, a device communication unit 250, and a notification unit 260.

The control unit 200 is a functional unit for controlling the entire connection device 2000. The control unit 200 realizes various functions by reading and executing various programs stored in the storage unit 210, and is composed of, for example, a CPU (Central Process Unit) or the like.

The storage unit 210 is a functional unit that stores various programs and various data necessary for the operation of the connection device 2000. The storage unit 210 is composed of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

The communication unit 220 is a functional unit for communicating with another device or an authentication card. For example, NFC (Near Field Communication) communication can be performed as short-range wireless communication. In the case of NFC communication, the authentication process is executed by holding the authentication card 65 over. When the measuring device 60 has an NFC communication function, biometric information can be received via the connecting device 2000 by holding the measuring device 60 over. The measuring device 60 may be, for example, a device such as a smartphone or a wearable terminal device such as a watch.

Of course, the communication unit 220 may use any method such as Bluetooth (registered trademark), TransferJet (registered trademark), ZigBee (registered trademark), or RFID. Further, a LAN (wireless LAN, wired LAN) or the like may be used.

The interface unit 230 is a functional unit for communicating with other devices. For example, it is provided as a functional unit for connecting to the state detection device 20. The interface to be connected may be realized by a dedicated interface or a general-purpose interface such as USB or RS-232C.

The device communication unit 250 is a functional unit for communicating between the display terminal 1000 and the connection device 2000 via the device communication unit 150 described above. For example, it may be connected using USB or the like, or it may be connected via a LAN. In this embodiment, for convenience of explanation, the configuration of the function of each communication unit is described separately, but it may be configured by one. That is, when all communication is performed by Bluetooth, the device communication unit 250, the communication unit 220, and the interface unit 230 are composed of one functional unit.

The notification unit 260 is a functional unit that operates when the connection device 2000 executes notification processing. For example, if you want to display an error, notify that fact. As a means for notifying, any method such as sound, light, display, and vibration can be considered.

[2.3 Electronic Medical Record Server]
Subsequently, the functional configuration of the electronic medical record server 40 will be described with reference to FIG. 7. The electronic medical record server 40 includes a control unit 400, a communication unit 410, and a storage unit 450.

The control unit 400 is a functional unit for controlling the entire electronic medical record server 40. The control unit 400 realizes various functions by reading and executing various programs stored in the storage unit 450, and is composed of, for example, a CPU (Central Process Unit) or the like.

The communication unit 410 is an interface unit for connecting to a network. For example, it is composed of a NIC that can be connected to Ethernet. It is possible to communicate with other devices via the communication unit 410.

The storage unit 450 is a functional unit that stores various programs and various data necessary for the operation of the electronic medical record server 40. The storage unit 450 is composed of, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

In addition, electronic medical record data 452 is stored in the storage unit 450. FIG. 8 shows an example of electronic medical record data. Patient information is stored in the electronic medical record data. For example, as shown in R100 of FIG. 8, basic information such as patient number and name, medical information such as the attending physician, and caution information indicating the patient's condition and the like are shown. (R102), pictogram, and measured biometric information (biological information value) (R104) are stored for each patient.

Here, the caution information is information for calling attention to convey the patient's condition to the medical staff, the caregiver, and the specialist. For example, information on alerting (prohibition of nasal blowing, etc.) and pressure ulcer assessment, fall risk assessment, etc. are stored as risk assessment. This information may be managed by flags, or may be managed by characters, icons, pictures, and the like.

In addition, pictogram information may be stored for easier understanding. Pictograms are based on information about everyday life. By displaying the pictogram, even a person who happens to pass by can give consideration to the patient, thereby providing safety and security. As described above, the pictogram information is the information that provides the patient's condition to many people, while the caution information is the information that conveys the patient's condition information to the specialist.

[3. Screen (state) transition diagram]
Subsequently, the flow of the entire system in this embodiment will be described with reference to the screen transition diagram (state transition diagram) of FIG.

First, when the system is started, it is determined whether or not the system is in an alarm state, that is, whether or not each biometric information value exceeds the alarm threshold value (or is less than the alarm threshold value). Then, the alarm screen (P100) is displayed as needed. This alarm screen confirms that a problem has occurred, but the details of the error are not displayed until you log in. This makes it possible to hide error content that should not be displayed to the patient or family.

The alarm screen is also displayed when the system is started, such as when the power is turned on, but it may be determined at any time whether or not the system is in the alarm state. Then, when an alarm state is reached, the interrupt processing may be configured to transition to the alarm screen.

Subsequently, the patient status display screen (P102) is displayed as the main status. On this screen, nameplate information, pictogram information, caution information, error status, etc. are displayed as basic patient information. This makes it possible to display necessary information for medical staff such as nurses and doctors, caregivers, and family members who are assisting.

The patient status display screen (P102) does not display detailed information because the patient, family members at the hospital, and third parties who have visited the hospital can also be seen. If necessary, the login screen (P104) is switched to by executing the authentication process and logging in. It is possible to transition to various screens from the login screen. For example, a patient information display screen (P114) capable of displaying patient information, a biological information display screen (P106) for displaying biological information values, a graph display screen (P108) capable of displaying a history of biological information values, and the like. It is possible to switch to the electronic medical record registration screen (P110) for registering the biometric information value in the electronic medical record.

Further, it is possible to switch to the alarm setting / history screen (P116) for setting the condition for the alarm state, and the reminder screen (P112) for setting the next action (for example, dosing instruction).

As described above, according to the present embodiment, it is possible to centrally display information about the patient, and it is possible to display appropriate information by switching the screen as needed. In addition, by centrally acquiring information on a plurality of measuring devices and registering them in an electronic medical record, it is possible to centrally manage information on patients.

[4. Explanation of each process]
Subsequently, each process in the present embodiment will be described with reference to the drawings.

[4.1 Main processing]
The main process in this embodiment will be described with reference to FIG. The main process is a process realized by the control unit 100 reading and executing the main program 132 stored in the storage unit 110.

First, it is determined whether or not it is in the alarm state (step S102). Specifically, each vital value is compared with the alarm threshold value, it is determined whether the alarm threshold value is exceeded or the alarm threshold value is less than the alarm threshold value, and whether or not an alarm should be issued is determined. Then, when it is necessary to issue an alarm, the alarm process is executed (step S102; Yes → step S104, FIG. 10).

Whether or not the alarm threshold is exceeded depends on the type of biometric information. In addition, both may be judged by a judgment criterion (that is, whether or not the vital value is within a predetermined range).

Subsequently, a patient state display process of determining the patient state and displaying the patient state based on the determined content is executed (step S106, FIG. 11). Here, if login authentication is not performed (or if login has failed), the process is repeatedly executed from step S102 (step S108; No → step S102).

Here, if the login authentication is correctly performed (step S108; Yes), the staff screen, which is the login screen, is displayed (step S110). The staff screen is a screen on which various processes can be selected. Here, when the staff processing is selected (step S112; Yes), the processing is executed according to the selected staff processing (step S114). Each process executed here will be described later.

If staff processing is not selected (step S112; No), or even after the staff processing is executed, if logout is not executed, the login state continues and the processing is repeatedly executed (step S116; No → step S110). ). On the other hand, if logout is executed, logout is performed, and the process is repeatedly executed from step S102 (step S116; Yes → step S102).

Here, the staff processing selected is the processing corresponding to P106 to P116 described in the screen transition diagram of FIG. The processing will be described using a processing flow and screen examples.

[4.2 Alarm processing]
The alarm processing will be described with reference to FIG. The alarm processing is a processing corresponding to P100 of FIG. 9 (step S104 of FIG. 10), and is a processing realized by the control unit 100 reading and executing the alarm program 134 stored in the storage unit 110. ..

First, it is determined whether or not there is a device connection error (step S202). If there is a device connection error here, the output of the device error is displayed (step S202; Yes → step S204).

Subsequently, it is determined whether or not there is biometric information that causes an alarm state (step S202; No → step S206 or step S204 → step S206). Specifically, each biometric information value is compared with the alarm threshold value to determine whether or not the alarm state is present. Then, if there is a value of biometric information that causes an alarm state (step S206; Yes), the notification process is executed (step S208).

As an example of the notification process, the notification process is performed from the notification unit 260, or the alarm screen is displayed on the display unit 170. At this time, the detailed information is not displayed until after logging in (after being authenticated).

Although the alarm processing has been described as being executed in step S104 of FIG. 10, it may be confirmed at regular time intervals and executed as interrupt processing.

In this way, if there is biometric information that is in an alarm state, it is possible to output an alarm by performing notification processing. Moreover, even if there is a device connection error, it is possible to output the device error as one of the alarms. The device connection error may be output as another method, or may not be output.

Further, the content of the alarm may be notified to the terminal device 50, the mobile terminal device 55, or the like. In this case, for example, the report destination may be changed or the report content may be changed according to the caution level or the warning level.

For example, for each patient, a table for storing how to make a report in association with the patient's condition and the type of biological information is stored. At this time, as the notification setting, "OFF" for not reporting, "Caution" for reporting at the caution level, and "Warning" for reporting at the warning level are stored. Further, depending on the type, "ON" and "OFF" may be simply set as if the person is out of bed.

In addition, the report destination may be determined in advance according to the report setting. For example, a "portable terminal device of a nurse in charge" and a "PC" at a nurse station or the like are set as the first report destination, and the "mobile terminal device of the nurse in charge" and "PC" are set as the second report destination. In addition to "", it is assumed that "the mobile terminal device of the doctor in charge" has been decided.

In this case, if the report setting is "ON" or "Caution", the report is sent to the first report destination. If the report setting is "warning", the report is sent to the second report destination. Further, in the present embodiment, the "nurse in charge" and the "doctor in charge" are extracted from the electronic medical record. In addition, it may be set as report destination information separately from the electronic medical record.

In this way, the content of the report according to the report setting may be reported to the preset report destination. In addition to being set for each patient, a common report destination may be set. For example, assume that a rapid response team is set at the emergency call destination for all patients. In this case, for example, when the biometric information value of the patient exceeds the threshold value having an emergency, or when a state of a plurality of warning levels occurs, the emergency call destination may be notified.

In addition, the report setting is set to report when the caution level and warning level are set, but it is set to each level or higher. For example, when the attention level is set, when the biometric information reaches the caution level, the first report destination is notified, and when the warning level is reached, the second report destination is notified. .. That is, the attention level includes the warning level. Depending on the setting, only the caution level may be reported.

[4.3 Patient status display processing]
[4.3.1 Processing flow]
The patient status display process will be described with reference to FIG. The patient status display process is a process corresponding to P102 of FIG. 9 (step S106 of FIG. 10), and is realized by the control unit 100 reading and executing the patient status display program 136 stored in the storage unit 110. Processing.

First, the individual electronic medical record data 120 is read out (step S302). Before reading the data of this electronic medical record, the patient authentication process may be executed and the authenticated patient data may be read.

Subsequently, a nameplate area is created from the basic information and medical information included in the individual electronic medical record data 120 (step S304), and a pictogram area is further created from the caution information and the set pictogram (step S306). ..

Specifically, the name plate area (name plate information on the display screen is displayed) from basic information such as the name, room number, and attending physician stored in the individual electronic medical record data 120 synchronized with the electronic medical record data 452 of the electronic medical record server 40. Area to be created) is created.

In addition, a pictogram display is created based on general caution information for the patient / caregiver stored in the individual electronic medical record data 120.

Subsequently, a warning area based on the caution information is created (step S308), and if there is error information, error information is generated (step S310). Here, the alert information displayed in the alert area is created based on the information for alerting an expert such as a medical worker or a caregiver. Therefore, the area is created in a state where the contents cannot be understood only by looking at it, such as patients and family members. In addition, the error information includes information related to the alarm, but the area is also created in a state where the content cannot be understood only by looking at it by a person other than a medical professional such as a patient or a family member.

Then, the patient status display screen is generated and displayed in each area created in the above-mentioned step (step S312).

[4.3.2 Patient status identification display processing]
Subsequently, the patient state identification display process is executed, and the patient state identification display is performed on the patient state display screen (step S314). Here, the patient state identification display process will be described with reference to FIG.

First, when the logout process is performed (step S352; Yes), the currently stored patient status information is cleared once (step S354). Then, continuous biometric information and measured biometric information are received (input) (step S356).

When the continuous biological information or the measured biological information is received, the current patient state (current patient state) is determined (step S358). Here, the current patient state is determined to be any of "warning", "caution", and "normal" based on all the received biometric information. Specifically, "Caution" if any of the biometric information values is included in the caution level of the alarm threshold, and "Warning" if any of the biometric information values is included in the warning level of the alarm threshold. It is determined.

Subsequently, the section patient status is updated (steps S362 to S370). Specifically, if the section patient state is "warning", the "warning" is maintained as it is (step S362; Yes).

Subsequently, if the section patient state is other than "warning" and the current patient state is "warning", the section patient state is set to "warning" (step S362; No → step S364; Yes → step S366). That is, when the section patient state is "attention" and "normal", if the current patient state becomes "warning", the section patient state becomes "warning".

If the section patient state is "normal" and the current patient state is "caution", the section patient state is set to "caution" (step S362; No → step S364; No → step S368; Yes → step. S370). That is, when the section patient state is "normal" and the current patient state becomes "caution", the section patient state becomes "caution". When the section patient state is "attention" and the current patient state is "normal" and "attention", the state of "attention" is maintained as it is (step S362; No → step S364; No → step S368; Yes → Step S370).

If the current patient state remains "normal" and the section patient state is "normal", the section patient state remains "normal" (step S362; No → step S364; No → step). S368; No).

In this way, when the patient state becomes a more important state such as "warning"> "caution"> "normal", the section patient state is updated in that state. In addition, once the state of high importance is reached, the state is maintained until the next time it is cleared (for example, until the timing of the next login).

Then, the patient state identification display is updated based on the patient state (interval patient state, current patient state) (step S372). This allows staff to easily see the current patient condition and the worst condition from the last logout to the present.

Then, the process is repeatedly executed from step S356 until the login process is performed again (step S374; No → step S356).

Here, the outline of the operation of the patient state identification display will be described with reference to FIG. FIG. 14A is an example of the identification display of the patient state displayed on the screen. The M102 has an identification display based on the section patient condition, and the M104 has an identification display based on the current patient condition. In the present embodiment, the identification display M104 is displayed larger in consideration of visibility, but the size may be the same, or a different shape and position may be used.

FIG. 14B shows an example of an identification display of each patient state. For example, M110 is normal, M112 is caution, and M114 is warning. This display may be changed depending on the color, movement, and shape. For example, in the case of color, normal may be displayed as "white", attention may be displayed as "yellow", and warning may be displayed as "red".

The operation will be briefly described with reference to FIGS. 14 (c) to 14 (e). It should be noted that the previous logout time is t1 and the current time point is t2.

In FIG. 14 (c), the patient state was "normal" at the time of t1, but then once changed to the "warning" state, and then changed to the "attention" state to reach t2.

In this case, the identification display M102 as the section patient state is displayed in the "warning" state because it is once "warning" after t1. Further, since (t2) is currently in the "caution" state, the identification display M104 is displayed as "caution".

In FIG. 14 (d), the patient state was in the “attention” state at the time of t1, but is currently in the “normal” state (t2). In this case, the identification display M102 as the section patient state is displayed as an identification display of the "attention" state. Further, since the identification display M104 is in the "normal" state at the time of t2, the identification display of "normal" is displayed.

FIG. 14 (e) is a diagram showing a case where the patient state was “normal” at the time of t1, but changed to “caution” and “warning” on the way. Even at present (t2), it is in a "warning" state. At this time, the identification display M102 indicating the section patient state becomes a "warning", and the identification display M104 indicating the current patient state also becomes a "warning".

Although the identification display is described as two in FIG. 14 for convenience of explanation, a plurality of identification displays may be provided correspondingly. For example, in addition to the above-mentioned identification display of the patient state (overall), the identification display based only on continuous biological information may be performed. In addition, a special identification display may be performed in association with predetermined biological information (for example, respiratory rate).

[4.3.3 screen example]
Next, a screen example will be described when this process is executed. FIG. 15 is an example of the patient status display screen W200. On the display screen W200, the name of the patient, the name of the attending physician, and the like are displayed in the areas R202 and R204 as nameplate information. These items are appropriately selected and displayed from the patient information registered in the electronic medical record.

Further, in the area R206, a pictogram or the like is displayed as a pictogram area. Further, in the area R208, special attention information is displayed from the caution information. The alert information is displayed only to specialists such as medical staff and staff of long-term care facilities.

Further, the R210 is notified that an error has occurred. Here, in order to display the error content, the authentication process must be executed and the screen must be switched to another screen. This makes it possible to prevent non-specialists such as medical staff and caregivers from confirming the error.

Further, the operation / state of the state detection device 20 may be displayed on the display screen W200. For example, as shown in the area R212, the state may be displayed. The connection status of the sensor is also displayed. This makes it possible to grasp at a glance whether the sensor is disconnected or unavailable.

In addition, the patient status identification display is performed. In FIG. 15, the identification display as the section patient state is displayed on the M200, and the identification display of the current patient state is displayed on the M202. Various methods are possible for the patient state identification display. For example, an underline may be displayed under the patient name, the identification may be displayed according to the color or line thickness, or an icon may be displayed separately. ..

Further, in the present embodiment, the patient state identification display is performed for the entire biological information including the continuous biological information and the measured biological information, but for example, the continuous biological information and the measured biological information may be displayed separately. However, the biometric information may be displayed separately for each biometric information, such as displaying only the respiration separately.

[4.4 Biological information display processing]
Next, the biological information display processing will be described. The biological information display process is a process corresponding to P106 of FIG. That is, it is a process of displaying a biometric information value based on a patient's electronic medical record data.

FIG. 16 shows a display screen W300 as a screen example when this process is executed. On the display screen W300, biometric information values are displayed for each biometric information. Further, in the area R302, the date and time when the displayed biometric information value is registered is displayed.

Further, next to the biometric information value, the alarm threshold value is displayed in the area R304 so as to be easy to understand. That is, the alarm threshold is displayed so that the attention level range and the warning level range are clear.

Further, the displayed biometric information value may have a configuration in which the background changes when it is within the range of the caution level and the warning level. For example, in R306, "126 bpm" is displayed as the pulse rate. Since this biometric information value is included in the attention level, the background is identified and displayed in the color of the attention level (for example, yellow).

In addition, various types of information may be identified and displayed in addition to the biological information. For example, the display of R308 identifies and displays that the pulse sensor is ON (that is, the pulse rate can be acquired as continuous biological information).

In addition, R310 is a display that calls attention to medical personnel, long-term care staff, and the like. For example, it is possible to identify and display biometric information that has a problem between the time of the previous log-out and the time of the current login. As a result, for example, when the patient state identification information is currently "attention", it is possible to confirm that there was a problem in breathing by logging in to the staff.

[4.5 Graph display processing]
Next, the graph display process will be described. The graph display process is a process executed on page 108 of FIG. That is, it is a process of displaying the transition of biometric information registered in the electronic medical record in a graph.

FIG. 17 shows a display screen W400 as a screen example when this process is executed. The display screen W400 displays the transition of each biometric information value. Then, the area of the alarm threshold value is also displayed on the graph of each biological information. This makes it possible to easily confirm when an abnormality has occurred in the biological information.

If one piece of biometric information is selected while this graph is displayed, a graph displaying only the biometric information may be displayed.

[4.6 Electronic medical record registration process]
[4.6.1 Processing flow]
Subsequently, the electronic medical record registration process for registering the biological information in the electronic medical record will be described with reference to FIG. The electronic medical record registration process is a process realized by the control unit 100 reading and executing the electronic medical record registration program 138 stored in the storage unit 110.

First, the patient information is read out (step S402), and the biological information of the patient is read out from the individual electronic medical record data 120 (step S404). The type of biometric information, alarm threshold value, etc. called here may be read out based on the basic information of the patient (for example, the ID of the patient), or may be set in common.

Subsequently, continuous biometric information is received from the state detection device 20, and the value of the received biometric information is displayed (step S408). Here, when there is an input instruction for the biometric information (step S410; Yes), the biometric information value is manually input (step S412).

At this time, if the biometric information value is in the alarm area, the identification display may be performed. For example, if the biometric information value is included in the caution level range, the background is displayed in yellow, and if it is included in the warning level range, the background is displayed in red or characters are displayed. As a result, the medical staff and the long-term care staff can grasp that the biometric information is currently causing a problem, and can call attention to input errors and the like.

Further, as the continuous biological information displayed on the display screen, the biological information (value of biological information) that can be detected from the state detection device 20 may be updated and read at any time and displayed, or may be read out at a certain timing. The biometric information may be displayed.

Further, when the measured biometric information is received from the other measuring device 60 (step S414; Yes), the measured biometric information is stored (step S416). In this case, the currently displayed biometric information value is updated and stored in the individual electronic chart data 120.

Here, the timing of the measured biological information received from the other measuring device 60 is not limited. In this figure, although it is described in step S416 as an example, the measured biometric information received in advance may be used. Further, the measured biological information stored in the individual electronic medical record data 120 (that is, the electronic medical record data 452) may be arbitrary. For example, if the value once measured is not correct, it may not be stored, and the remeasured value may be stored.

Then, when there is an instruction to register the electronic medical record (step S418; Yes), the electronic medical record data 452 of the electronic medical record server 40 is registered (step S420).

[4.6.2 screen example]
FIG. 19 is a diagram showing a display screen W500 which is an example when this process is executed. On the display screen W500, each biological information and the value of the biological information are displayed. Similar to FIG. 16, the alarm threshold value is displayed in the area R502, and when each biometric information value is at the caution level and the warning level, the identification display is set as R504.

Further, as shown in the area R506, the previously measured value may also be displayed. The date and time when the previous measured value was measured is also displayed at the upper part of the biological information. As a result, medical staff, long-term care staff, and the like can notice the transition of biometric information values.

Further, as for the displayed biometric information value, the value updated in real time may be displayed for the continuous biometric information, or the value at a certain time point may be displayed. Further, the value stored in the electronic medical record data (individual electronic medical record data 120 or electronic medical record data 452) may be displayed.

Then, by selecting "Registration" from this screen, the currently displayed biometric information value can be registered (stored) in the electronic medical record data. In addition, the past biometric information value can be referred to by referring to the history.

[4.7 Reminder processing]
Next, the reminder process will be described. The reminder process is a process that allows staff and medical staff (nurses, etc.) to register what to do next as a reminder. For example, FIG. 20 is an example of a display screen W600 displayed when this process is executed. By registering the work to be displayed as various reminders, it is possible to display it on the patient status display screen or the alarm display screen.

[4.8 Patient information display processing]
Next, the patient information display process will be described. The patient information display process is a process capable of displaying information about a patient. For example, it is possible to display, input, and set basic patient information, medical care information, caution information, pictograms, and the like.

For example, FIG. 21 is an example of a display screen W700 displayed when this process is executed. The display screen W700 reads out basic information (basic information) such as a patient's name, gender, and blood type from an electronic medical record and displays it.

[4.9 Alarm setting / history processing]
Next, alarm setting and history processing will be described. This process is a process that can set each alarm threshold value and set whether or not an alarm can be performed. It is also possible to check the alarms that have occurred in the past as a history.

FIG. 22 is an example of the display screen W800 displayed when the alarm setting / history processing is executed. The display screen W800 can set an alarm threshold value. For example, as the upper limit alarm threshold value, the threshold value in the attention level range can be set in R804, and the threshold value in the warning level range can be set in R802.

Further, as the lower limit alarm threshold value, the threshold value in the attention level range can be set in R808, and the threshold value in the warning level range can be set in R806.

In addition, it is possible to set whether or not to output an alarm when the attention level and the warning level are entered. For example, in the case of showing by R810, it is set not to output (not notify) as an alarm.

The display screen W850 of FIG. 23 is set to output an alarm when the attention level is reached by R850. In this setting, for example, sound or light may be set, or an alarm different from the attention level and the warning level can be set.

[5. Effect of configuration of patient status display device]
And, it is one of the features in this embodiment that these screens can be displayed in a place different from the bed 3. This makes it easier for nurses and doctors to refer to patient information, and even if the beds are changed, appropriate patient information can be displayed.

In particular, in the past, the display screen provided on the bed was not easy to use, and the pictogram displayed on the bedside had to be updated each time.

Further, the information that can be acquired in the bed (for example, the continuous biological information of the present embodiment) and the information that can be acquired from the measuring device (for example, the measurement biological information of the present embodiment) need to be managed separately. All of these can be connected via the patient status display device 10 (connection device 2000), and can be further stored in an electronic medical record.

Further, FIG. 24 is an example of a case where the connection device 2000 is notified of an error. The display terminal 1000 is connected to the connecting device 2000 and is integrally arranged on the bedside.

Here, for example, when the state detection device 20 cannot be connected, "sensor connection" is displayed in the area R900. If there is no error in this area, nothing is displayed. As a result, no matter what screen the display terminal 1000 has, or even if the display terminal 1000 cannot be displayed (for example, when the display terminal 1000 is out of order or the display terminal 1000 is not connected). It is possible to reliably notify important errors and the like.

Further, the error notification may be notified based on the patient's condition. In this case, a display (symbol, code, etc.) that cannot be understood by the patient, family, or the like may be displayed. Further, as the notification method, not only the display but also, for example, sounding or notification to the mobile terminal device 55 may be performed.

[6. Service provision / other provision by server]
Although the processing in the above-described embodiment has been described as being performed by the patient status display device 10 for convenience of explanation, the processing may be executed by the server 30 and the result may be received by the patient status display device 10.

That is, various programs (for example, the main program 132, the alarm program 134, the patient status display program 136, and the electronic medical record registration program 138) are executed on the server 30 as needed. The same processing can be realized by transmitting biometric information from the patient status display device 10 to the server 30 and accessing the server 30 with, for example, a WEB browser or a dedicated application.

Further, although the patient status display device 10 is also configured as a display terminal 1000 and a connection device 2000, it may be provided as an integrated patient status display device 10.

By separating the display terminal 1000 and the connection device 2000, the display terminal 1000 has an advantage that a tablet terminal satisfying a predetermined condition can be used. As a result, it is conceivable to use a commercially available tablet terminal or computer, or to use a smartphone.

Further, although the patient status display device 10 is generally provided near the bed, the same screen can be displayed by the terminal device 50 and the mobile terminal device 55. For example, even when a nurse is patrolling, patient information can be confirmed with the mobile terminal device 55, and by using the terminal device 50 at the nurse station, it is possible to collectively manage patients including other patients. Become.

In addition, the biometric information can be updated at any time by using the terminal device 50 even during medical examinations and examinations, which improves the usability of the electronic medical record.
