Description

  The present invention relates to an unlocking system for unlocking a door of a hospital room or the like, and more particularly to an unlocking system for preventing nosocomial infection by a visitor.

  Conventionally, in addition to patients in a hospital room, medical staff such as doctors and nurses, an unspecified number of people such as patients in other hospital rooms and visitors have entered a hospital room. When an unspecified number of people entered a hospital room, nosocomial infections mediated by those who entered the hospital sometimes occurred.

In this way, in order to prevent nosocomial infection caused by unspecified number of people entering the hospital room, an ID (Identification) card given to a specific person is read when entering the hospital room, and the ID card is A technique is known that unlocks an electronic lock installed on a door of a hospital room when entry is permitted (for example, Patent Document 1).
JP 2006-53675 A

By the way, in the technique described in Patent Document 1, it is necessary to give an ID card not only to a medical worker but also to a visitor. In that case, nosocomial infections may occur through medical workers and visitors who have ID cards that are allowed to enter. As a technique for preventing such nosocomial infections, a technique is known in which biometric information of a hand inserted in a disinfectant tank is read and personal authentication and hand disinfection are performed simultaneously (for example, Patent Document 2). Such).
JP 2007-185424 A

  However, in the technique described in Patent Document 1, a visitor who has been given an ID card can unlock the electronic lock and enter the hospital room simply by reading the ID card. There was a problem that the possibility of forgetting would increase. In addition, in the technique described in Patent Document 2, for the visitor who first visited the hospital, biometric information must be registered, compared with the technique described in Patent Document 1 that passes the ID card, There was a problem that the procedure would be very troublesome. On the other hand, if there are disinfection facilities in the nurse center where there are medical workers, there are cases where the medical workers have already completed disinfection when they enter the room, and the fingers are disinfected twice. There was a problem that the efficiency of medical staff would deteriorate.

  The present invention has been made to solve such a problem, and disinfecting fingers when entering a sickroom for a visitor while preventing an unspecified number of people from entering the sickroom. The purpose is to allow the medical staff to enter the hospital room without having to disinfect the fingers when entering the hospital room.

  In order to solve the above-described problems, in the present invention, identification information for medical workers and general-purpose identification information for other people are set for each hospital room as identification information that permits entry. . A storage device storing the identification information for medical workers so as to be readable is handed over to the medical staff, and a storage device storing the general-purpose identification information so as to be readable is handed over to other people. When the identification information of the storage device is read in order to unlock the electronic lock in the hospital room, the electronic lock is unlocked if the identification information is the identification information for the medical staff. On the other hand, if the identification information is general-purpose identification information, guidance for prompting disinfection of fingers is performed, and the electronic lock is unlocked when an operation for discharging the disinfecting liquid is performed.

  According to the present invention configured as described above, since the electronic lock of the hospital room is not unlocked unless the identification information permitted to enter the hospital room is read, the entry to the hospital room of an unspecified number of people is restricted. can do. Moreover, since the electronic lock is unlocked simply by reading the identification information for the medical staff, disinfection of fingers when entering the hospital room can be omitted, and the efficiency of the medical staff is improved. be able to. In addition, for visitors, etc., when the identification information is read, guidance is given to sterilize the fingers, and the electronic lock is unlocked only when the disinfectant is discharged. Hands can be disinfected when entering the room.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of an unlocking system according to the present embodiment. As shown in FIG. 1, the unlocking system according to the present embodiment includes a medical worker ID card (corresponding to a medical worker storage device in claims) 1a, a general-purpose ID card (claims). 1b, control unit 2, electronic lock 3, reading unit 4, disinfectant storage unit 5, discharge operation unit 6, announcement unit 7, storage unit 8, reading determination unit 9, entry permission determination unit 10, the identification information determination unit 11 is provided.

  The ID card 1a for medical staff is used by medical staff who are permitted to enter a hospital room. The medical worker ID card 1a stores medical worker identification information for identifying the medical worker to be used. Here, the identification information for medical workers is stored in the ID card 1a for medical workers so as to be readable by the reading unit 4 described later. Moreover, the medical worker always carries the same ID card 1a.

  The general-purpose ID card 1b is used by a person other than a medical worker and is used by a person who is permitted to enter a hospital room. The general-purpose ID card 1a stores general-purpose identification information for identifying a person to be used. Here, the general-purpose identification information is stored in the general-purpose ID card 1b so as to be readable by the reading unit 4 described later. In addition, a person other than a medical worker indicates a patient or a visitor. The patient receives the general-purpose ID card 1b at the time of hospitalization and returns it at the time of discharge. The visitor receives the general-purpose ID card 1b at the time of receiving the visit and returns it when returning home.

  In this embodiment, an ID card is used as a storage device that stores identification information for medical staff and general-purpose identification information. However, the present invention is not limited to this. For example, any device may be used as long as it can store (or record) identification information, such as a tag in which a barcode is described as identification information or a wireless terminal capable of transmitting identification information.

  The control unit 2 controls each component of the unlocking system (except for the ID cards 1a and 1b) according to the present embodiment. The electronic lock 3 is installed on the door of the hospital room and is for locking or unlocking the door of the hospital room. Here, since a known technique is used for the configuration of the electronic lock 3, the description thereof is omitted. The reading unit 4 is for reading the identification information stored in the ID cards 1a and 1b, and reads the identification information when the ID card 1a and 1b approaches within a certain range of the reading unit 4. Here, the reading unit 4 is installed in the vicinity of the door of the hospital room, and outputs the read identification information to the control unit 2.

  The disinfecting liquid storage unit 5 includes a tank that stores the disinfecting liquid. The disinfectant is guided from the opening provided in the tank to the discharge port provided near the door of the hospital room and discharged outside. The disinfecting liquid storage unit 5 controls the discharge of the disinfecting liquid to the outside by a movable valve or the like provided near the opening or the discharge port. Here, the discharge port is installed in the vicinity of the door of the hospital room. Further, the discharge port is installed at a height at which a person can easily disinfect his / her fingers.

  The discharge operation unit 6 is operated to discharge the disinfecting liquid from the disinfecting liquid storage unit 5 to the outside, and includes a push button or the like. When the discharge operation unit 6 is operated, the movable valve of the disinfecting liquid storage unit 5 is opened for a certain time, and a certain amount of the disinfecting liquid is discharged from the discharge port. Here, the discharge operation part 6 is installed in the vicinity of the door of a hospital room. In addition, the discharge operation unit 6 is installed in the vicinity of the discharge port so that a person who operates the discharge operation unit 6 can easily disinfect a finger using a disinfecting liquid discharged from the discharge port.

  The announcement part 7 is comprised by sound emission apparatuses, such as a speaker, and is installed in the vicinity of the door of a hospital room. In addition, although the announcement part 7 by this embodiment is comprised by the speaker, it may be comprised by a display display, a warning light, etc., and may be comprised combining these. In addition, the announcement unit 7 outputs sound stored in the storage unit 8 described later.

  The storage unit 8 stores medical worker identification information and general-purpose identification information. In addition, the storage unit 8 stores room identification information for identifying each room. Here, the storage unit 8 stores the identification information for the medical staff and the general-purpose identification information in association with the room identification information of the room permitted to enter the room. For example, for a medical worker who is allowed to enter all hospital rooms, the medical worker identification information of the ID card 1a for the medical worker handed over to the medical worker is stored in association with all the hospital room identification information. The part 8 is memorized. For inpatients who are only allowed to enter their own room, the general-purpose identification information of the general-purpose ID card 1b to be given to the patient is stored in the storage unit 8 in association with the room-room identification information of the patient's room. is doing. For a visitor who is only allowed to enter the visitor's room, the storage unit associates the general-purpose identification information of the general-purpose ID card 1b to be passed to the visitor with the patient-room identification information of the patient's room of the visitor 8 is remembered.

  Further, the storage unit 8 stores audio data of audio output from the announcement unit 7. For example, voices such as “Please press the button to disinfect your fingers” to encourage visitors to disinfect their fingers, or voices such as “Do not enter this room” are prohibited. I remember it. The general-purpose identification information and the room identification information are associated with each other and stored in the storage unit 8 in advance, and when the ID card 1b is given to a patient or a visitor, the general-purpose identification already stored in association with the room identification information. If the ID card 1b having information is selected, it is not necessary to perform the association work one by one.

  The reading determination unit 9 determines whether the reading unit 4 has read the medical worker identification information or the general-purpose identification information. In other words, it is determined whether or not an ID card 1a for medical personnel or a general-purpose ID card 1b has been deceived by the reading unit 4. When the control unit 2 inputs the identification information from the reading unit 4, the reading determination unit 9 determines that the reading unit 4 has read the identification information.

  When the room admission determination unit 10 determines that the reading determination unit 9 has read the identification information, is the identification information read by the reading unit 4 stored in association with the room identification information of the hospital room in which the reading unit 4 is installed? Determine whether or not. When the reading determination unit 9 determines that the reading unit 4 has read the identification information, the control unit 2 operates the room entry permission determination unit 10. The room admission determination unit 10 reads out the room identification information of the hospital room in which the reading unit 4 is installed from the storage unit 8, and stores the medical worker identification information and / or general-purpose identification stored in association with the read out room identification information. Information is read from the storage unit 8. Whether the identification information (the identification information for medical staff or the general-purpose identification information) input from the reading section 4 by the control unit 2 is included in the read identification information (the identification information for medical staff and / or the general-purpose identification information). (In other words, whether there is identification information that matches the input identification information). When the identification information read by the reading unit 4 is not stored in association with the room identification information, the room entry permission determination unit 10 obtains a result of room entry non-permission. On the other hand, when the identification information read by the reading unit 4 is stored in association with the room identification information, the room entry permission determination unit 10 obtains the result of room entry permission.

  Here, when the room permission determination unit 10 obtains the result of the room refusal, the control unit 2 acquires the voice data from the storage unit 8, and the announcement unit 7 "is prohibited from entering this room". The sound is output. On the other hand, when the room permission determination unit 10 obtains the result of room permission, the control unit 2 operates the identification information determination unit 11.

  The identification information determination unit 11 determines whether the identification information read by the reading unit 4 is identification information for medical staff or general-purpose identification information. Then, when the identification information determination unit 11 determines that the identification information read by the reading unit 4 is identification information for medical staff, the control unit 2 unlocks the electronic lock 3.

  On the other hand, when the identification information determination unit 11 determines that the identification information read by the reading unit 4 is general-purpose identification information, the control unit 2 acquires audio data from the storage unit 8 and the announcement unit 7 Press the button to disinfect your fingers ". In this state, when the discharge operation unit 6 is operated within a predetermined time, the control unit 2 unlocks the electronic lock 3. On the other hand, if the discharge operation unit 6 is not operated within a predetermined time, the control unit 2 ends the process. Here, the predetermined time is measured by a timer (not shown).

  Next, the operation of the unlocking system and the unlocking method according to this embodiment will be described. FIG. 2 is a flowchart showing the operation of the unlocking system and the unlocking method according to this embodiment. First, the reading determination unit 9 determines whether the reading unit 4 has read the identification information (step S1). If the reading determination unit 9 determines that the reading unit 4 has not read the identification information (NO in step S1), the process of step S1 is repeated.

  On the other hand, when the reading determination unit 9 determines that the reading unit 4 has read the identification information (YES in step S1), the read identification information is associated with the room identification information of the patient room in which the reading unit 4 is installed. Whether or not it is stored in the storage unit 8 is determined by the entrance permission determination unit 10 (step S2). When the room entry permission determination unit 10 determines that the read identification information is not stored in the storage unit 8 in association with the room identification information of the hospital room in which the reading unit 4 is installed (NO in step S2), step The process returns to S1. In addition, as mentioned above, although the announcement part 7 may guide that entry into a hospital room is prohibited, since it is not essential, description is abbreviate | omitted.

  On the other hand, when the room entry permission determination unit 10 determines that the read identification information is stored in the storage unit 8 in association with the room identification information of the hospital room in which the reading unit 4 is installed (YES in step S2). Then, the identification information determination unit 11 determines whether or not the read identification information is identification information for medical staff (step S3). If the identification information determination unit 11 determines that the read identification information is medical staff identification information (YES in step S3), the process proceeds to step S7.

  On the other hand, when the identification information determination unit 11 determines that the read identification information is not medical worker identification information (NO in step S3), the control unit 2 acquires voice data from the storage unit 8. Announcement unit 7 provides guidance for sterilization of fingers (step S4). Then, the control unit 2 checks whether or not the discharge operation unit 6 has been operated and the disinfection liquid discharge operation has been performed (step S5). If the control unit 2 determines that the disinfectant discharge operation has been performed (YES in step S5), the process proceeds to step S7.

  On the other hand, when the control unit 2 determines that the disinfectant discharge operation has not been performed (NO in step S5), the control unit 2 checks whether a predetermined time has elapsed (step S6). ). If control unit 2 determines that the predetermined time has elapsed (NO in step S6), the process ends. If control unit 2 determines that the predetermined time has not elapsed (YES in step S6), the process returns to step S5.

  In step S7, the control unit 2 unlocks the electronic lock 3. When the electronic lock 3 is unlocked, a medical worker who dresses the ID card 1a for medical staff as the reading unit 4, and a patient or a visitor who dresses the general-purpose ID card 1b as the reading unit 4, It becomes possible to enter the room.

  As described above in detail, according to the present embodiment, the identification information for permitting entry into the room is the identification information for medical workers and the general identification information for other persons (patients, visitors, etc.) Is stored in the storage unit 8 in association with the hospital room identification information. Then, the ID card 1a storing the medical worker identification information so as to be readable is handed over to the medical worker, and the ID card 1b storing the general-purpose identification information so as to be readable is handed over to other people. When the reading unit 4 reads the ID card 1a or ID card 1b in order to unlock the electronic lock 3 in the hospital room, if the identification information is the identification information for medical personnel, the control unit 2 uses the electronic lock 3 To unlock. On the other hand, if the identification information read by the reading unit 4 is general-purpose identification information, the announcement unit 7 provides guidance for sterilization of fingers, and the control unit 2 holds the electronic lock 3 when the discharge operation unit 6 is operated. I try to unlock.

  Thereby, unless the identification information permitted to enter the hospital room is read, the electronic lock 3 in the hospital room is not unlocked, so that it is possible to limit the entrance of an unspecified number of people into the hospital room. Moreover, since the electronic lock 3 is unlocked simply by reading the identification information for the medical staff, disinfection of fingers when entering the hospital room can be omitted, and the efficiency of the medical staff is improved. Can be made. In addition, when the identification information is read for a visitor, guidance for prompting disinfection of fingers is performed, and the electronic lock 3 is unlocked only when the disinfectant is discharged. Hands can be disinfected when entering the room.

  In the above-described embodiment, the electronic lock 3 is unlocked only when entering the room, but the present invention is not limited to this. For example, the electronic lock 3 may be unlocked only when leaving the room, or the electronic lock 3 may be unlocked both when entering the room and when leaving the room.

  In the above-described embodiment, the control unit 2, the storage unit 8, the reading determination unit 9, the entrance permission determination unit 10, and the identification information determination unit 11 are not quoted. It may be installed in the vicinity, or may be installed in a management room or a nurse center that manages each hospital room.

  In the embodiment described above, the disinfectant is used as a means for disinfecting the fingers, but the present invention is not limited to this. For example, it may be a gas or a solid.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.

It is a block part which shows the structural example of the unlocking system by this embodiment. It is a flowchart which shows the operation | movement of the unlocking system by this embodiment, and the unlocking method.
