  The operation of the nurse call system configured as described above is as follows. First, a case where the staff call button 14 is operated will be described. When the staff call button 14 of the nurse call cordless handset 1 is pressed, a staff call signal is transmitted from the nurse call cordless handset 1 to the corridor lamp 2, and the corridor lamp 2 that receives the staff call signal has the indicator light 2a serving as the staff call. A notification operation is performed by performing a predetermined lighting operation indicating patient information, and patient information such as a patient name of the caller is displayed on the patient display unit 2b. In the corridor lamp 2, caller information such as hospital room number information and bed number information (nurse call cordless handset number information) is attached to the staff call signal and transmitted to the controller 5.

  Upon receiving the staff call signal from the corridor lamp 2, the controller 5 reads the hospital room number and bed number attached to the staff call signal by the controller CPU 57 and selects the associated camera 6 from the camera information storage unit 53. And get the captured video. Then, the acquired captured video (hereinafter simply referred to as “video”) is transmitted to the nurse call parent device 3 together with the staff call signal. Also, recording to the video storage unit 56 is started.

The controller CPU 57 refers to the portable terminal table storage unit 51, the assigned nurse table storage unit 52, the patient information storage unit 54, and the like to the portable terminal 4 related to the caller information together with the staff call signal and the caller. Send patient information and video. This signal and video are transmitted to the portable terminal 4 via the exchange 7 and the base station 8.
The portable terminal 4 that has received the staff call signal or the like rings a predetermined ringing tone for notifying the staff call and displays patient information and a patient image on the display 4a. FIG. 4 shows the portable terminal 4 thus displaying the patient video on the display 4a.

  On the other hand, the nurse call parent device 3 that has received the staff call signal and the video is notified of the ringing tone by the control of the parent device CPU 35, and the patient call based on the information of the nurse call child device 1 attached to the staff call signal. The caller's patient information is read from the information storage unit 54 and displayed on the display unit 3b. Further, the corresponding patient notification lamp 37 on the board 3c is turned on, and the received video is displayed on the display 3b.

When the nurse call master unit 3 to which the staff call ringing sound is reported and a response operation is performed with the handset of the communication unit 3a, a response signal is transmitted to the control unit 5, and the control unit CPU 57 and the nurse call slave unit 1 and the nurse call A communication path with the base unit 3 can be formed to make a call. Thus, the nurse can make a call with the nurse who has operated the staff call button 14 while viewing the patient image. In addition, the control unit CPU 57 receives the response signal from the nurse call master unit 3 and terminates the transmission of the video and the stuff call signal that has been performed to the portable terminal 4. Note that video recording and video display on the nurse call parent device 3 are continued.
Thereafter, when the nurse call master unit 3 is operated to end the call, the controller CPU 57 cuts off the communication path and ends the imaging of the camera 6 to end the recording. The video is stored in association with the call history.

  On the other hand, when the mobile terminal 4 responds, it is as follows. When the portable terminal 4 is subjected to a predetermined response operation, a response signal is transmitted to the controller 5 via the base station 8 and the exchange 7. Receiving this response signal, the controller 5 forms a speech path between the nurse call slave unit 1 and the portable terminal 4 by the controller CPU 57. Thus, a call can be made, and the nurse can make a call with the nurse who has operated the staff call button 14 while confirming the patient's condition from the video displayed on the portable terminal 4.

Further, the controller CPU 57 that has received the response signal from the portable terminal 4 ends the transmission of the video and the staff call signal that has been performed to the other portable terminals 4 and the nurse call parent device 3. Note that video recording and video display on the portable terminal 4 that has formed a communication path are continued.
Thereafter, when the mobile terminal 4 is operated to end the call, a call end signal is transmitted to the controller 5, and the controller CPU 57 cuts off the speech path and ends the imaging of the camera 6 to end the recording.

In this way, even if the mobile terminal 4 responds, the captured image of the camera 6 is stored in the controller 5 and the transmission of the video to devices other than the device that has responded in response to the response operation ends, thus protecting the privacy of the patient. The camera image can be used while maintaining The patient's video at the time of the call operation is saved in the same storage unit regardless of the responding device, so that the patient's state at the time of the call can be easily confirmed later, which is useful for nursing records and explanation to family members. be able to.
Further, since only the video of the staff call calling with a high priority is stored, the video storage unit 56 can be used effectively, and the situation where the video storage unit 56 overflows immediately can be prevented.

  On the other hand, the call by the call button 16 operates the camera 6 but does not record. In addition, the call by the drip button 17 and the toilet assistance button 18 does not perform imaging by the camera, and if a call is made by operating the staff call button during these call operations, the staff call call is given priority, Controlled to respond.

  Hereinafter, the operation when the call button 16 of the nurse call handset 1 is operated will be briefly described. When the call button 16 of the nurse call cordless handset 1 is operated and a call is made, a call signal is transmitted to the corridor lamp 2, and the indicator lamp 2a performs a predetermined light emitting operation to notify the occurrence of the call, and displays patient information. The caller's patient information is displayed in the section 2b. Then, caller information such as hospital room number information and bed number information (nurse call child machine number information) is attached to the staff call signal and transmitted to the controller 5 in the call signal.

  In the controller 5 that has received the call signal from the corridor lamp 2, the controller CPU 57 reads the hospital room number and bed number attached to the call signal, selects the associated camera 6 from the camera information storage unit 53, and The captured video is obtained, and the video is transmitted to the nurse call parent device 3 together with a call signal. Also, the caller's patient information and video are transmitted together with the call signal to the portable terminal 4 related to the caller information. The mobile terminal 4 that has received the calling signal rings the calling information and displays the patient information and the patient video on the display 4a.

In the nurse call parent device 3 that has received the calling signal, the calling sound is reported under the control of the parent CPU 35, and the calling source is called from the patient information storage unit 54 based on the nurse call child device information attached to the calling signal. Patient information is read and displayed on the display unit 3b. Further, the corresponding notification lamp 37 of the board unit 3c is turned on, and the received video is displayed on the display unit 3b.
In the nurse call master device 3 that has received the call in this manner, when a response operation is performed with the handset or the like of the communication unit 3a, the control device 5 forms a communication path between the nurse call slave device 1 and the nurse call master device 3 to perform the call. This enables nurses to talk to patients while watching patient images.

When the mobile terminal 4 responds, the controller 5 forms a communication path between the mobile terminal 4 and the nurse call handset 1 so that a call can be made. Then you can enter the call.
Thus, even when calling by the call button 16, it is possible to respond while watching the patient image, so that the patient's condition can be grasped.

In the above-described embodiment, only the staff call is recorded. However, the recording may be performed by adding the operation of the call button 16 or may include the toilet assistance call.
In addition, it is desirable to record multiple videos at the same time when staff call calls occur repeatedly. However, if the recording circuit is a simple circuit that cannot record multiple videos at the same time, give priority to the recording of the previous call and respond. By recording a later call from the point of time, it is possible to check the patient's condition later after storing the video for a short time.
Further, the video is stored in the controller 5 and the controller CPU 57 controls the video. However, the nurse call master unit 3 is provided with a video storage unit, and the master unit CPU 35 performs the control of the captured video of the camera 6. Also good. Furthermore, when a server for managing patient information is connected, video may be stored in the server.
