  In the event of a large number of patients at once due to the occurrence of a major disaster, the hospital will need to install temporary beds in the hallways and empty spaces in addition to the beds in the hospital room to accommodate and treat as many patients as possible. . However, a conventional hospital cannot assign a nurse call cordless handset to a temporary bed installed in such an emergency. As a result, the patients who were housed were unable to make a nurse call using the nurse call handset, and it was difficult for doctors and nurses to figure out how many patients were carried and were currently hospitalized. . Furthermore, even when a call is made from a patient, the calling patient may not be easily recognized.

  Therefore, in view of such problems, the present invention can make a nurse call using a nurse call cordless handset from a temporary bed installed in a corridor or the like in a hospital, and a nurse can call from a temporary bed. An object of the present invention is to provide a nurse call system that can easily identify a patient who has made a nurse call.

A first controller IF 30, a second controller IF 31 for communicating with the outlet device 2, and the like.

  In the nurse call system configured as described above, the operation associated with the connection / disconnection of the nurse call slave unit will be mainly described below. FIG. 3 shows a display on the display 20 when the system is started up. FIG. 4 shows a screen in which the outlet device 2 and the controller 4 communicate with each other after the start-up to display the connection state of the nurse call slave unit 1. Show. A shows the ward layout, and rooms B1 to B6 and corridors C1 and C2 are arranged inside, and D is a bed mark indicating the position of the nurse call slave 1 (the position of the outlet device 2 to which the nurse call slave 1 is connected). Mark).

  As shown in FIG. 3, when the nurse call system is activated, the controller CPU 29 reads the ward layout information from the layout storage unit 28 and transmits it to the nurse call master 3, and the master CPU 24 displays the ward layout A on the display 20. To do. Thereafter, the controller CPU 29 starts communication with the outlet device 2, obtains connection information of the nurse call slave unit 1 from each outlet device 2, and the bed mark D is displayed on the ward layout as shown in FIG. The

  Specifically, the outlet CPU 15 detects whether or not the nurse call slave unit 1 is connected based on the terminal resistance value of the outlet second IF 17 and the like, and transmits a connection signal / non-connection signal to the controller 4 when the system is activated. Receiving the connection signal / connection signal, the control unit CPU 29 searches the location information of the outlet device 2 stored in the layout storage unit 28, adds the searched location information, and nurses the slave unit connection signal / subunit connection release signal. Send to call base unit 3. The outlet CPU 15 periodically transmits a connection signal / non-connection signal.

The nurse call master unit 3 is displayed on the display 20 when the master unit CPU 24 receives a slave unit connection signal from the control unit 4 among the slave unit connection signal / slave unit connection release signal including the position information of the outlet device 2. A bed mark D corresponding to the position of the outlet device 2 is displayed on the ward layout A. On the other hand, the corresponding bed mark D is not displayed for the outlet device 2 that has transmitted the slave unit connection release signal. Thus, the layout image of FIG. 4 is displayed.
FIG. 4 shows a normal state in which the nurse call cordless handset 1 is connected to the outlet device 2 in the hospital room, but the nurse call cordless handset 1 is not connected to the outlet device 2 installed in the hallway. Is shown.

  However, in the event of an emergency such as an earthquake, it is not enough to place a bed in a hospital room, and it is necessary to place a temporary bed in an empty space such as a hallway. In such a case, the outlet device 2 installed outside the hospital room is utilized. In the nurse call system of the present invention, the outlet device 2 installed in the hallway is also installed on the assumption that the bed is arranged.

Therefore, the nurse call cordless handset 1 can be provided for each temporary bed arranged. When the nurse call slave device 1 is connected to the outlet device 2, the bed mark D is displayed on the display 20 of the nurse call master device 3 by the above-described operation. That is, the outlet device 2 that has detected the connection of the nurse call slave unit 1 transmits a connection signal to the controller 4 under the control of the outlet CPU 15. The controller CPU 29 receives this connection signal, reads the position of the corresponding outlet device 2 from the layout storage unit 28, and transmits a child device connection signal to which the position information is added to the nurse call parent device 3.
In response to the slave unit connection signal, the master unit CPU 24 displays the bed mark D at a corresponding location on the ward layout A displayed on the display 20. The display of the display 20 on which the bed mark D is displayed in this way is shown in FIG.

  In this state, when a nurse call occurs, for example, when a call is made from the nurse call handset 1 installed in the corridor C1, a call signal is transmitted to the controller 4 via the outlet device 2. The controller 4 generates a call signal obtained by adding the position information of the outlet device 2 to the call signal, and transmits the call signal to the nurse call parent device 3.

In response to this call signal, the master CPU 24 causes the corresponding bed mark D to blink among the bed marks D in the ward layout displayed on the nurse call master 3. Thus, the place where the nurse call is made is displayed on the display 20. The master CPU 24 simultaneously reports a ringing tone from the master speaker 21.
FIG. 6 shows a display on the display 20 at this time. The hatched bed mark D1 blinks to indicate that the corresponding nurse call slave unit 1 has been called. This display allows the nurse to recognize the caller at a glance.

In this way, the nurse call slave unit can be installed in accordance with the bed arranged in the hallway in addition to the hospital room, and the position of the nurse call slave unit can be displayed on the display based on the position information of the outlet device. That is, even a hospitalized patient in the corridor can display the location on the display of the nurse call master unit. Therefore, even in an emergency where the inpatient is also in the corridor, the inpatient can easily make a nurse call, and hospital staff such as nurses can grasp the patient's position from the display, regardless of where the patient is. It is possible to perform treatment and nursing work without delay for nurse calls.
In addition, since the position of the nurse call slave unit is displayed on the display as the position of the bed that is actually placed, the position of the patient can be visually recognized, and the nurse can easily cope with it.

  Next, the operation when the connection to the outlet device 2 is disconnected in the nurse call slave 1 connected as described above or the transmission line L1 of the nurse call slave 1 is disconnected will be described. When disconnection such as disconnection occurs in the nurse call slave unit 1 connected to the outlet device 2, the outlet CPU 15 detects the disconnection and transmits a disconnection signal to the controller 4. The controller CPU 29 that has received the non-connection signal after receiving the connection signal reads the position of the corresponding outlet device 2 from the layout storage unit 28 in response to this non-connection signal, and nurses the slave unit disconnection signal to which the position information is added. Send to call base unit 3.

  The master CPU 24 that has received the slave device disconnection signal blinks the bed mark D displayed at the corresponding position on the display 20 in a state different from the nurse call display. At the same time, an alarm sound is reported from the main unit speaker 21 and a disconnection alarm is reported. FIG. 7 shows a state in which the nurse call cordless handset 1 installed in the corridor C2 is detached and the corresponding bed mark D2 blinks to notify it. Due to this change in display, the location where the disconnection occurs can be recognized on the display, and the nurse can easily identify the location and can deal with it smoothly.

  The slave unit disconnection signal is generated when the controller CPU 29 determines that the disconnection has occurred when the disconnection signal is continuously transmitted from the same outlet device 2 that has received the transmission of the connection signal. In the state where the system is activated, the controller CPU 29 only receives the disconnection signal and generates a slave unit connection release signal, but does not generate a slave unit disconnection signal.

And when this disconnection alarm is continuing, if the reset button provided in the nurse call parent device 3 is operated, the alarm operation is reset. Specifically, the master CPU 24 displays a reset button (not shown) in accordance with blinking of the bed mark D on the display 20 to display disconnection. When the reset button is touch-operated (a touch panel is assembled to the display 20 to be an operation unit for performing various operations), a reset signal is issued from the master CPU 24, and the alarm operation is reset and stopped.
The reset signal is transmitted to the controller 4, and the controller CPU 29 receiving the reset signal stops transmitting the slave unit disconnection signal, returns to the initial setting, and deletes the bed mark D at the corresponding position on the display 20. . However, the display continues if the reset button is not pressed.
It should be noted that it is preferable not to display the reset button for the disconnection alarm in the hospital room, which is preferable because it can prevent a situation where the display disappears accidentally.

In this way, when the nurse call cordless handset is disconnected from the outlet device, a disconnection alarm is issued in the nurse call master cord, so the nurse call slave can be surely notified of the disconnection, and the disconnection can be notified from the patient. The situation where the nurse call does not reach the nurse call master unit can be prevented. In addition, since the alarm is stopped by performing the reset operation, the temporary bed can be moved or removed without difficulty even if the alarm is configured.
And since it is not judged that the nurse call cordless handset is disconnected for the outlet device which is not connected from the beginning, no false alarm is generated.

In the above embodiment, the controller performs the same control for all the outlet devices 2, but only the outlet device 2 installed in the hospital room generates a child device disconnection signal and nurses. The call master unit 3 may be configured to issue an alarm. With such a configuration, regarding the outlet device 2 installed in the hallway, only the display / non-display according to the connection status of the nurse call slave device 1, that is, the bed installation status, is performed. Since no alarm is issued even if 1 is removed, it is easy to move or remove the temporary bed. On the other hand, since a warning is issued when a disconnection occurs such as when the nurse call cordless handset 1 is disconnected in the hospital room, the nurse can be surely recognized.
Further, the display of the bed mark D on the display 20 may be a display form different between the hallway and the hospital room. Specifically, the dead mark D installed in the corridor is displayed only when the nurse call handset 1 is connected, and the bed mark D in the hospital room is related to whether the nurse call handset 1 is connected or not. Instead, it may be controlled by the master CPU 24 so that it is always displayed. By displaying in this way, in the normal state where there is no bed in the corridor, it is possible to display the same display as the conventional nurse call system, and it is possible to ensure the stability of control in the normal state.

Furthermore, in the above embodiment, the ward layout A is displayed on the display 20, but the layout of the entire hospital may be displayed, and the layout storage unit 28 is provided in the controller 4, but the nurse call master 3 May be provided. Further, although the controller CPU 29 grasps the position of the outlet device 2, the parent device CPU 24 may grasp and control it.
In addition, although the nurse call slave unit connection information is transmitted from the outlet device 2 to the controller 4, it may be generated and transmitted from the connected nurse call slave unit 1, or may be transmitted from the controller 4 to each outlet device 2 or You may confirm with respect to each intercom subunit | mobile_unit 1 by a ping process.
