Radio transmitters carried by the patient and transmitting ID signals, 6, 6 .. is a wireless receiver that receives an ID signal transmitted by a wireless transmitter.

The nurse call cordless handset 1 is connected to the corridor lamp 2 via the cordless handset transmission line L1 for each hospital room, the corridor lamp 2 is connected to the controller 4 via the corridor lamp transmission line L2, and the nurse call master set 3 Is connected to the controller 4 via the master transmission line L3.
In addition, the wireless receiver 6 is installed in each hospital room, and is installed in a predetermined part outside the hospital room such as a corridor and a toilet, and an area where the patient carrying the wireless transmitter 5 may move at least normally in the hospital. If so, one of the wireless receivers 6 is arranged so as to receive the ID signal. Among them, the radio receiver 6 installed in each hospital room is connected to the corridor lamp 2 via the receiver transmission line L4, and the radio receiver 6 installed outside the hospital room such as the corridor and the toilet passes through the corridor lamp transmission line L2. Via the controller 4.

The nurse call handset 1 includes a call grip button 1a that performs a call operation, and a wall-embedded handset 1b that includes a microphone and a speaker and includes an outlet for the call grip button 1a. The corridor lamp 2 includes a patient information display unit 2a for displaying patient information of a corresponding hospital room and a display lamp 2b for displaying a call.
The nurse call master unit 3 is a board type master unit, and includes a handset 3a for responding to a call from a patient, a display unit 3b for displaying a patient who has performed a call operation, and a display board 3c for displaying a list of patient information. ing.

The wireless transmitter 5 and the wireless receiver 6 perform transmission and reception by RFID (Radio Frequency Identification), the wireless transmitter 5 includes an RFID tag (IC tag), and the wireless receiver 6 includes an RFID receiver 10. It has been incorporated. The RFID receiving unit 10 is configured to output an ID request signal at a predetermined interval and receive an ID signal transmitted from the IC tag in response to the request.
In addition to the RFID receiver 10, the wireless receiver 6 includes a timer (receiver timer) 11, an interface (receiver IF) 12 for communicating with the controller 4, and a CPU (receiver) that controls the wireless receiver 6. CPU) 13.

  The controller 4 includes a controller storage unit 15 that stores the relationship between the ID signal transmitted by the wireless transmitter 5 and the reception location (wireless receiver installation location), a timer (controller timer) 16, and a CPU that controls the controller ( A controller CPU) 17 and an interface (controller IF) 18 for communicating with each device are provided. The controller storage unit 15 stores a database as shown in FIG. In this database, the reception location (indicated by the room number and location name) and the validity / invalidity of the notification are set for each ID number, and the wireless receiver 6 that has received the ID signal sends a predetermined signal to the controller. 4, the controller 4 determines whether the signal is valid and performs predetermined alarm control, or determines whether the signal is invalid and does not perform alarm control.

  The operation of the nurse call system configured as described above is as follows. However, since the nurse call slave unit 1 is operated to make a call and the nurse call base unit 3 responds to the basic operation of the nurse call in the same manner as before, the description thereof is omitted, and the wireless transmitter 5 and the wireless receiver are omitted. The detection operation in the case where an abnormality occurs in the patient and the detection operation of the patient who is hesitant will be described focusing on the operation 6.

  First, the operation when an abnormality occurs in a patient will be described based on the flowchart of FIG. The wireless receivers 6 provided in each hospital room and corridor perform ID signal reading operations at regular intervals, and when a patient carrying the wireless transmitter 5 approaches, an ID signal transmitted by the wireless transmitter 5 is transmitted. Receive (S1). When the read ID signal is an ID signal received for the first time, the receiver timer 11 is operated under the control of the receiver CPU 13 to start measuring a predetermined time. Thereafter, the reception operation is continuously performed at regular intervals to confirm the received ID signal (S2), and it is determined whether the ID signal is the same as the previous one (S3). If they are the same, the count is continued. Otherwise, the count is terminated. Thus, when the same ID signal is continuously received, the receiver timer 11 eventually times out (S4), and a patient abnormality detection signal including the received ID information is transmitted to the controller 4.

  The controller 4 that has received the patient abnormality detection signal reads the valid / invalid information stored in the controller storage unit 15 from the ID signal and the location information included in the signal received under the control of the controller CPU 17, and When the ID signal is received at the registered location, an alarm signal is transmitted to the nurse call parent device 3. The nurse call master unit 3 that has received the alarm signal sounds an alarm sound (S5), and the detected patient information and detected location information are displayed on the display unit 3b and the like based on the patient information and location information included in the alarm signal. Is done.

  For example, when the controller 4 receives a patient abnormality detection signal with ID number 002 from the wireless receiver 6 installed in the hospital room 101A from the database of FIG. Since is set to be effective, an alarm signal is transmitted to the nurse call parent device 3. When the patient abnormality detection signal with ID number 003 is received from the wireless receiver 6 installed in the hospital room 101A, the received patient abnormality detection signal is discarded as invalid because the invalid setting is made, and an alarm signal is sent. Do not send.

In this way, patients that do not move in the hospital can be detected and notified to the nurse call parent machine, so if you carry a wireless transmitter to people who are concerned about the health condition such as hypertensives or elderly people, It is possible to quickly recognize and notify an unexpected situation such as falling down, and to respond smoothly in an emergency.
In addition, depending on the valid / invalid setting, even if the patient stays for a certain period of time in the patient room or area where the patient may stop as well as his / her own room, an abnormality will occur. It is possible to provide a system with few false alarms.
Further, by using RFID, the wireless transmitter can be reduced in size and easily carried, and can be implemented with an inexpensive configuration. And since a transmission radio wave is a weak radio wave, even if a patient carries a medical device, it does not have influence.

  Next, the detection operation when the patient starts wrinkling will be described based on the flowchart of FIG. Similar to the above-described abnormality detection, the wireless receiver 6 performs a receiving operation at regular intervals, and receives the ID signal of the carried wireless transmitter 5 when the patient approaches. When the ID signal is received, a location confirmation signal including the location information and the received ID information is transmitted to the controller 4.

  If the received location confirmation signal is a signal including an ID signal registered in advance in the controller storage unit 15, the controller 4 stores the reception time every time it is received and counts a predetermined time by the controller timer 16. Start. Then, the count-out of the controller timer 16 is judged (S11). If the received signal with the same ID is obtained from any of the radio receivers 6 before counting out (S13), the controller timer 16 is reset and starts a new count (S14).

  When the controller timer 16 finishes counting the predetermined time and counts out, that is, when the specific ID signal that has started the timer count has not been received for a predetermined time, the controller CPU 17 detects the patient unknown signal. Is transmitted to the nurse call parent device 3 to cause the nurse call parent device 3 to sound an alarm sound (S12) and to display on the display unit 3b and the like that the location of the patient corresponding to the ID signal is unknown.

  In this way, if the patient's location becomes unknown, it can be detected, so it is possible to quickly recognize when the deceased leaves the hospital, etc., and deal with it before the deceased goes far away It becomes possible.

  In the above-described deaf person detection operation, when the same ID signal cannot be received for a certain period of time, when all the wireless receivers have not received it, that is, when they have left the hospital, Although the control is performed so that it is determined that it is unknown by issuing a report, it may be configured to perform a report operation when a part of an area, for example, a floor where a sick person's hospital room is located and another floor is used. In this case, it can be easily implemented by creating a map in which valid / invalid areas are set for each wireless transmitter 5, 5,... And storing it in the controller 4 or the like. Can be detected before leaving the hospital, so it is possible to deal with the deceased at an early stage.

In the above embodiment, the wireless receiver 6 is made to determine when the patient has stopped moving (ID information management means for managing the reception location and reception time of the ID signal is provided in the wireless receiver 6). The wireless receiver 6 may perform only the reception of the ID signal and allow the controller 4 to make a determination in the same manner as the detection of wrinkles.
Furthermore, in the said embodiment, although the structure which installed one radio | wireless receiver 6 with respect to each hospital room is shown, you may install a radio | wireless receiver with respect to each nurse call subunit | mobile_unit 1, If there are toilets and bathrooms in the room, a wireless receiver 6 may be separately installed in those places.
Further, although the communication between the wireless transmitter 5 and the wireless receiver 6 is RFID, a conventional configuration in which the wireless transmitter 5 is always a transmission type may be used.
