  By the way, in a call operation from a normal nurse call master unit, a signal for performing a call with the nurse call slave unit 1 from the master unit CPU 30 is controlled via the master unit data transmission / reception circuit 31 and the control unit data transmission / reception circuit 51. The controller CPU 30 is transmitted to the machine CPU 30 via the controller data transmission / reception circuit 51 and the hall light data transmission / reception circuit 23, and transmits a signal notifying the start of the call to the hall light CPU 20, and the controller call control circuit 52. Is controlled by connecting the communication path between the corridor lamp and the nurse call master unit.

  In addition, the patient ID information of the patient who visits is set in the transmission device 6.

  The operation of the nurse call system according to the present invention will be described below in a state where such settings are made in advance.

  First, as a first embodiment, when a visitor carries the transmission device 6 and approaches the hospital room, the reception device 7 provided in the vicinity of the corridor lamp 2 installed near the entrance of the hospital room. Is detected, and an approach signal is transmitted to the corridor lamp CPU 20 via the corridor lamp data transmission / reception circuit 23 to notify that the transmitting device has approached.

  When the corridor lamp CPU 20 receives the approach signal and collates the patient ID information and determines that the visitor is addressed to the patient in the room, the corridor lamp data transmission / reception circuit 23 and the controller data transmission / reception circuit 51 send a visitor notification signal to notify the visitor. Then, the data is transmitted to the control unit CPU 50 and to the base unit CPU 30 via the corridor lamp data transmission / reception circuit 23, the control unit data transmission / reception circuit 51, and the base unit data transmission / reception circuit 31.

  When the master CPU 30 receives the visitor notification signal, the master CPU 30 controls the display device 33 to display that the visitor has come to the room by the screen or / and the indicator lamp of the display device, and also controls the master phone sound generation circuit 32. The nurse is also notified that the visitor has come to the room by ringing the parent speaker 34.

  Further, the corridor lamp CPU 20 transmits a call restriction signal for notifying the restriction of the call to the controller CPU 50 via the corridor lamp data transmitting / receiving circuit 23 and the controller data transmitting / receiving circuit 51 following the transmission of the visitor notification signal.

  When receiving the call restriction signal, the controller CPU 50 controls the controller call control circuit 52 so as not to connect the call path between the corridor lamp 2 and the nurse call master unit 3.

  In this state, when a call operation is performed from the nurse call master unit to the patient, a signal for performing a call with the nurse call slave unit is transmitted from the master unit CPU 30 to the master unit data transmit / receive circuit 31 and the controller data transmit / receive circuit 51. To the controller CPU 50. However, since the controller CPU 50 has already controlled the controller call control circuit 52 so as not to connect the communication path between the corridor lamp 2 and the nurse call parent unit 3, the nurse call child unit to the nurse call parent unit The incoming call signal is restricted and the call is not established.

  Next, the operation of the second embodiment will be described. The second embodiment is an example when the patient operates the call restriction notification button 15 of the nurse call handset 1. Note that the process up to the part where the master CPU 30 receives the visitor notification signal is the same as in the first embodiment, and the description thereof is omitted.

  In the second embodiment, when the corridor lamp CPU 20 detects that the call restriction notification button 15 provided in the nurse call cordless handset 1 has been operated after transmitting the visitor notification signal, the corridor lamp CPU 20 detects the corridor lamp data transmission / reception circuit. 23, a signal notifying the restriction of the call is transmitted to the controller CPU 50 via the controller data transmission / reception circuit 51.

  When receiving the call restriction signal, the controller CPU 50 controls the controller call control circuit 52 so as not to connect the call path between the corridor lamp 2 and the nurse call master unit 3. In this state, when a call operation is performed from the nurse call master unit to the patient, a signal for performing a call with the nurse call slave unit is transmitted from the master unit CPU 30 to the master unit data transmit / receive circuit 31 and the controller data transmit / receive circuit 51. Via the controller CPU 50. However, since the controller CPU 50 has already controlled the controller call control circuit 52 so as not to connect the communication path between the corridor lamp 2 and the nurse call parent unit 3, the nurse call child unit to the nurse call parent unit The incoming call signal is restricted and the call is not established.

  In FIG. 1, the receiving device 7 is connected to the corridor lamp data transmission / reception circuit 23, but it may be connected to the controller data transmission / reception circuit 51 to transmit an approach notification signal from the controller CPU 50.

  Furthermore, after the visitor visits the hospital room, the corridor lamp CPU 20 generates a call restriction signal and transmits it to the controller CPU 50 via the corridor lamp data transmitter / receiver circuit 23 and the controller data transmitter / receiver circuit 51. When detected by the receiving device 7, the corridor lamp CPU 20 determines that the visitor has left the hospital room, generates a visitor end signal, and passes through the corridor lamp data transmission / reception circuit 23 and the controller data transmission / reception circuit 51. The signal is transmitted to the CPU 50 via the corridor lamp data transmission / reception circuit 23, the controller data transmission / reception circuit 51, and the parent device data transmission / reception circuit 31, and the corridor lamp CPU 20 transmits a call signal to the nurse call slave unit 1 in the hospital room. A call restriction release signal for releasing the restriction is generated and the corridor lamp data transmission / reception circuit 23 and the controller data transmission / reception circuit 51 are used. It can be transmitted to the controller CPU 50. In this way, the controller CPU 50 detects the call restriction release signal and releases the restriction on the reception signal from the nurse call slave unit to the nurse call master unit.

  In addition, since the nurse call cordless handset 1 is provided with a call restriction restoration button 16 that allows the patient to release the restriction on the call, the corridor lamp CPU 20 generates a call restriction signal to generate the corridor lamp data transmission / reception circuit 23, When it is detected that the call restriction restoration button 16 of the nurse call cordless handset 1 has been operated after being transmitted to the controller CPU 50 via the controller data transmission / reception circuit 51, the corridor lamp CPU 20 generates a call restriction release signal to generate a call restriction release signal. The data is transmitted to the controller CPU 50 via the lamp data transmitter / receiver circuit 23 and the controller data transmitter / receiver circuit 51. The controller CPU 50 detects the call restriction release signal and restricts the reception signal from the nurse call slave unit to the nurse call master unit. You may make it cancel.

  Furthermore, since the nurse call cordless handset 1 is provided with a call button 10 for the patient to call the nurse, the corridor lamp CPU 20 detects that the call button 10 of the nurse call cordless handset 1 has been operated and calls it. A signal is generated and transmitted to the controller CPU 50 via the corridor lamp data transmitter / receiver circuit 23 and the controller data transmitter / receiver circuit 51, and the controller CPU 50 that detects the calling signal releases the restriction on the call signal, and the nurse call slave unit 1 It is also possible to make a two-way call in which both the reception signal and the transmission signal can be transmitted to and from the nurse call parent device 3.

  Further, the controller CPU 50 can forcibly transmit a transmission signal from the nurse call parent device 3 to the nurse call child device 1 even when there is a restriction on the call signal. In this way, for example, even in the event of an emergency, a one-way call between the nurse call master unit 3 and the nurse call slave unit 1 can be made promptly, and communication items from the nurse center can be communicated to the patient. it can.

  Note that the mobile terminal 4 carried by the nurse may be included in the call restriction target. The portable terminal 4 includes a terminal ringing tone generation circuit 40, a terminal data transmission / reception circuit 44, a terminal call circuit 43, a terminal microphone 41, a terminal speaker 42, and the like. For example, the terminal data transmission / reception circuit 44 and the controller data transmission / reception circuit of the controller 5 The call restriction signal can be transmitted and received to and from 51.

It is a block diagram showing embodiment of the nurse call system of this invention.
