Can be recognized.
Even if the abnormality of the connected device does not recover or the recovery button that stops the notification of the occurrence of the abnormality is not operated, if the alarm sound stop operation is performed, the alarm sound will not sound after that. The teacher can concentrate on nursing work without being aware of the recovery of the device with the abnormality. In addition, since the display of the device abnormality on the nurse call parent device is continued until the recovery operation is performed, there is no possibility that the recovery of the connected device is neglected.

According to a second aspect of the present invention, in the configuration according to the first aspect, the notification operation by display is a pop-up display and a telop display, and the notification control unit is included in the abnormality occurrence signal when a new abnormality occurrence signal is received. The room number and bed number are read from the information, the generated room number and bed number are displayed in a pop-up display, and the contents of the abnormality based on the abnormality occurrence signal are displayed in telop, and only the telop is displayed when an alarm sound is stopped. It is characterized by.
According to this configuration, when a device abnormality occurs, the hospital room number and bed number are displayed in a pop-up, and the content of the abnormality is displayed in telop, so it is easy to confirm the location even if the display unit itself is a relatively small screen, Abnormal contents can be easily grasped. In addition, even if it is configured to notify by pop-up display, there is no pop-up display after the alarm sound stop operation, so it is possible to solve the problem of hiding other information displayed on the display part, disturbing the nurse work There is no.

According to a third aspect of the present invention, in the configuration according to the second aspect, the notification control unit displays the room number and the bed number together with the telop display when receiving the alarm sound stop operation.

Provided in each patient information display section M is a notification lamp 39 that emits light to notify the caller, a parent communication IF 40 for LAN connection with other nurse call devices such as the controller 4 and the like.
Reference numeral 42 denotes a hook switch for turning on / off the handset 41, and has a function of stopping an alarm sound to be described later.

The operation of the nurse call system configured as described above is as follows. The operation of the corridor lamp 2 in response to the call operation of the nurse call slave unit 1 and the response operation by the nurse call master unit 3 or the portable terminal 6 is the same as the conventional one, so the explanation is omitted here. The notification operation when the call button 1a is dropped from the plate slave unit 1b or the cord 18 for connecting to the plate slave unit 1b of the call button 1a is disconnected will be mainly described. .
If the call button 1a connected to the connection terminal 13 of the plate slave unit 1b is disconnected or if a break occurs in the cord 18 of the call button 1a, the drop / break detection unit 12 detects this and drops to the slave CPU 15・ Notify the occurrence of disconnection. For example, the drop / break detection unit 12 detects a change in the inter-terminal resistance value of the connection terminal 13, and determines that the call button 1a is dropped or disconnected when the resistance value changes (when it increases).

When the drop / break detection unit 12 detects the occurrence of the drop / break, the slave CPU 15 receives it and monitors it for a certain time (for example, 20 seconds), and the drop / break detection unit 12 drops even after a certain time has elapsed. If the occurrence of disconnection continues to be detected, a drop / break signal is transmitted to the corridor lamp 2 via the slave unit communication IF 16. The slave CPU 15 outputs a drop / break signal at regular intervals as long as the drop / break detection unit 12 continues to detect the occurrence of the drop / break.
Even if the occurrence of dropout / breakage is detected, it is possible to prevent a deliberate removal operation such as reconnection from being judged as dropout by waiting for a certain period of time. In addition, the output of the drop / break signal is reset once by the operation of the recovery button 14.

  The corridor lamp 2 that has received the disconnection / disconnection signal from the nurse call cordless handset 1 reads the hospital room number information and the bed number information of the sender nurse call cordless handset 1 from the corridor lamp storage unit 22 and adds them to the corridor. A drop / break signal with the original information added is transmitted to the nurse call master unit 3 and the controller 4 via the HUB 10.

  The nurse call master unit 3 that has received the drop / break signal displays the occurrence of the drop / break on the display unit 3b under the control of the master CPU 35, and simultaneously reports an alarm sound from the sound report unit 38 and drops / breaks. Perform notification operation of occurrence of Specifically, the hospital room number and bed number are read from the received drop / break signal, and the video processing unit 32 is controlled to pop up the hospital room number and bed number on the display unit 3b. Further, the abnormal content is grasped from the dropout / breakage signal, and the abnormal content to be notified is displayed as a telop at the bottom of the display unit 3b. Then, an alarm sound is generated from the report sound unit 38.

  The alarm sound is generated when the master CPU 35 newly receives a drop / break signal, and once a warning sound stop operation described later is performed, a drop / break signal transmitted from the same transmission source. In response to this, there is no warning sound unless a recovery operation is performed. Further, the controller 4 that has received the drop / break signal records the occurrence of the drop / break in the call history.

  FIG. 5 shows a state in which the display unit 3b displays the occurrence of dropout / breakage. As shown in FIG. 5, in the main area of the display unit 3b, the display E1 of the room number “102” and the display E2 of the bed number “4” are displayed large by the pop-up display D1, and at the bottom of the display unit 3b The telop D2 “The button is disconnected from the outlet” is displayed. Here, also in the pop-up display D1, the cause information of the occurrence of abnormality (caused by the occurrence of dropout / disconnection) is also displayed. The text information of the telop is stored in advance in the information storage unit 34, and the display “button is disconnected from the outlet” is displayed gently to the nurse who confirms. May be displayed correctly.

The sounding operation is continued until a predetermined stop operation (in this case, an operation for raising the handset 41 of the calling unit 3a) is received. By raising the handset 41, the hook switch 42 is turned off to generate a trigger for stopping the reporting sound, and the master CPU 35 that receives this trigger signal stops the reporting sound. On the other hand, the display by the telop D2 is continuously performed.
However, the notification operation by the continuous display does not perform the pop-up display D1 and the report sound notification but only displays the telop D2. At that time, the room number and the bed number are displayed together in the telop D2.

  FIG. 6 shows a display state of the dropout / breakage notification after the second time. Specifically, a state in which a dropout / breakage notification has been made after receiving a report sound stop operation in a state where the caller's patient information and patient video are displayed after receiving the call is shown. As shown in FIG. 6, the pop-up display is not performed, and the notification operation is performed only by displaying the telop D2, so that a call from the patient occurs and the patient information is dropped on the display unit 3b. -Even if notification of disconnection occurrence is made, the display of the caller's patient information is not hidden.

On the other hand, as long as the restoration operation is not performed, the nurse call slave unit 1 sends a drop-off / disconnection signal at a predetermined time (for example, 20 seconds). Therefore, when the alarm sound stop operation is not performed, the display by the telop is continuously or intermittently performed, and the alarm sound is continuously or intermittently reported until the stop operation is performed.
Then, when the recovery button 14 of the nurse call cordless handset 1 that is the source of the dropout / breakage is pressed, a spread signal is transmitted from the slave CPU15, and the dropout / breakage signal is stopped from the slave CPU15, and the nurse call master 3 The notification operation ends.

However, the operation of the recovery button 14 alone does not fix the dropout / breakage. Therefore, when the dropout / breakage detection unit 12 detects the dropout / breakage, the slave CPU 15 sends a new dropout / breakage signal after a certain period of time. To start. In this case, since the master CPU 35 recognizes it as a new drop-off / disconnection signal, it starts notification by an alarm sound and display.
In addition, if the dropout / breakage is restored by repair or replacement, then no dropout / breakage notification will occur.

As described above, when the call button 1a connected to the connection terminal 13 is dropped or disconnected, the nurse call master unit 3 is notified of this by an alarm sound and display. You can be sure. Therefore, it is possible to prevent a situation in which a call signal is not transmitted even when the call button 1a is operated.
Even if the dropout / breakage is not recovered or the recovery button 14 is not operated, if the alarm sound is stopped, the alarm will not sound even if the recovery operation is delayed. You can concentrate on nursing work without being aware of the recovery of the device. Further, since the drop / break display on the nurse call master unit 3 is continued until the recovery operation is performed, there is no possibility that the call button 1a will not be recovered.
In addition, if a dropout or disconnection occurs, the hospital room number and bed number are displayed in a pop-up, and a telop display indicates that the alarm is due to the dropout or disconnection occurrence, so the location can be confirmed even if the display itself is a relatively small screen. It is easy to do, and it is easy to grasp the abnormal contents.
In addition, even if it is configured to notify by pop-up display, there is no pop-up display after the alarm sound stop operation, so it is possible to solve the problem of hiding other information displayed on the display part, disturbing the nurse work There is no. And when there is no pop-up display for displaying the location, the location information is also displayed on the telop, so it can be dealt with smoothly.

In the above embodiment, the configuration for notifying the occurrence of the dropout / breakage of the call button 1a has been described. However, when another device is connected to the connection terminal 13, for example, when a biological information measuring device is connected, the same applies. Dropping / breaking can be detected.
Further, the dropout / breakage detection unit 12 detects dropout / breakage by a change in the resistance value between the terminals, etc. If other detection functions such as determination by setting a plurality of threshold values for the detection resistance value are added, for example, connection It is also possible to detect and notify device malfunctions and the like.
In addition, when the display unit 3b is formed with a large display of about 20 inches, for example, the occurrence of dropout / breakage may be notified by a pop-up display even after the alarm sound is stopped, or the first display may be displayed by a telop display. It is also possible to display information on the origin of dropout / breakage from
