The operation of the nurse call device configured as described above is as follows. Since the operation of making a nurse call call by the operation of the slave unit 1 and executing the call between the patient and the nurse by the response operation of the master unit 3 is the same as the conventional operation, the explanation is omitted here. The operation when the button 35a is operated will be described.
When the listening button 35a of the second operation unit 35 of the master unit 3 is operated, the mode shifts to the setting mode in which the listening destination is selected and set under the control of the master unit CPU 38. When the mode shifts to the setting mode, the operated patient is set as the listening destination by operating the predetermined portion of the patient information display unit P displayed on the first display 32.

Specifically, when shifting to this listening mode, the first display 32 is implemented as the state of the patient information display unit M, and when shifting to the setting mode, the notification of each patient information display unit P of the displayed patient information list is performed. The light P3 becomes a setting button for setting the listening destination, and when the notification light P3 of the patient to be listened to is touch-operated, the patient is set as the listening destination. That is, the notification light P3 operated at this time is the notification light P3 of the patient in the private room, and the hospital room in which the notification light P3 is operated is set as the listening destination. For example, when the notification light P3 of each patient in the private rooms 601 to 603 shown in FIG. 3 is touch-operated, these three rooms are set as listening destinations.

In this way, when one or more hospital rooms to be listened to are selected and set, the listening mode is shifted to and simultaneous listening is started by operating the listening start button (not shown) displayed on the second operation unit 35. To.
When the mode shifts to the listening mode, the listening voice management unit 43 is activated by the control of the controller CPU 44 in the controller 4, and the voice (voice data) transmitted from the slave unit 1 is not directly transmitted to the master unit 3 and is buffered. It is temporarily stored in the section 42. That is, the voice data collected by the microphone 11 of the slave unit 1 in the selected hospital room and transmitted via the corridor light 2 is temporarily stored in the buffer unit 42 under the control of the listening voice management unit 43, and then temporarily stored in the buffer unit 42. It is sequentially transmitted to the master unit 3.

Specifically, the voices are transmitted from the selected hospital rooms to the controller 4 so as to overlap each other, but are transmitted on different channels for each hospital room and are independently stored in the buffer unit 42 for each slave unit 1.
While the audio data is stored in this way, the listening audio management unit 43 takes out the audio data from the buffer unit 42 in the order of transmission and transmits the audio data to the master unit 3. However, when the voice of the slave unit 1 is interrupted for a certain period of time (for example, 1 second), the slave unit 1 to be transmitted is switched, and each time the voice is interrupted, the voice data of the slave unit 1 transmitted next is switched. In this way, the switching is sequentially performed, and the voices of all the selected slave units 1 (hospital rooms) are sequentially transmitted.
In the master unit 3 to which the voice data is transmitted, the voice is reported from the handset 31a of the communication unit 31 or the speaker.

Further, while the listening mode is set, the display form of the notification light P3 of the selected patient in the patient information list is displayed differently from that of the other notification lights P3 by the control of the master unit CPU 38, and the listening destination is set. The patient can be easily grasped on the patient list display unit M.
Further, the notification light P3 of the source of the voice currently being reported operates in a state different from the notification lights of the patients at other listening destinations, and it is easy to grasp which patient's voice is being reported. Display and operate as you can. The master unit CPU 38 determines the slave unit 1 from the ID information of the slave unit 1 attached to the received voice data, and changes the display color of the corresponding patient notification light P3.
For example, when three rooms, rooms 601 to 603, are selected as listening destinations, the notification light P3 of the patient in this room is green in the standby state, but emits light in orange, for example, during the listening mode. Further, when the voice currently being reported by the master unit 3 is the voice of the patient in room 601, the notification light P3 of the patient in room 601 is in a blinking orange state.

In this way, even if audio is transmitted from the plurality of slave units 1 at the same time by operating the listening button 35a, it is temporarily stored in the controller 4 and sequentially sent from the controller 4 to the master unit 3. The voices sent to 3 are sent without overlapping. Therefore, a plurality of voices are not overlapped and reported from the speaker or the like of the master unit 3, and the nurse can understand the words of each patient.
In addition, since the display form of the notification light P3 of the patient in the hospital room to be listened to is different from the surroundings, the hospital room to be listened to can be grasped from the patient list display unit M, and the hospital room currently being reported is also included. It can be grasped by changing the display form of the notification light P3, and the nurse can easily grasp which of the plurality of hospital rooms being listened to and the hospital room currently being reported. In addition, since the notification light P3 is used as the listening destination display unit, it is not necessary to newly provide the listening destination display unit.

In the above embodiment, the notification light P3 is used as the listening destination display unit, but when the patient list display unit M is displayed on a display made of an LCD, the entire patient information display unit P is displayed as the listening destination display. The overall light emitting form may be changed as a unit, or a dedicated display unit may be provided as a listening destination display unit in the patient information display unit P.
Further, although the patient room to be listened to is input from the first display 32 (first operation unit 34) using the patient list display unit M, the second display which is the second operation unit 35 provided with the listening button 35a. You may select a hospital room by inputting a hospital room number from 33 (second operation unit 35) using a numeric keypad or the like. On the contrary, the listening button 35a may be provided on the first operation unit 34, and the transition to the setting mode and the transition to the listening mode may all be performed on the first display 32, and the first operation unit 34 and the second operation may be performed. The operation button setting of the unit 35 may be set from the viewpoint of operability and convenience.
Furthermore, although the listening destination is a private room, in the case of selecting the listening destination by the notification light P3 as described above, it can be set for each patient, so that a specific patient in the large room can be set as the listening target. It is possible.
