  By the way, when the nurse call system described in Patent Document 1 is applied, in order for a medical worker to grasp whether or not the mobile communication terminal is calling, it is necessary to look at the display of the nurse call parent device. However, if a medical worker is in a place where he cannot see the display of the nurse call master unit, he / she cannot grasp the status of the call operation of the mobile communication terminal. Therefore, when all the mobile communication terminals are not calling, a medical worker who cannot see the display of the nurse call parent device calls all the mobile terminal devices in response to a call from the patient. There was a problem of not being able to grasp what was not done.

  The present invention has been made to solve such a problem. When all the mobile communication terminals are not calling, a medical worker who cannot see the display of the nurse call master unit is provided. It is an object to increase the possibility that it is possible to grasp that all the mobile terminal devices are not calling in response to a call from a patient.

  In order to solve the above-described problem, in the nurse call system of the present invention, when a portable communication terminal capable of responding to a call signal from a nurse call slave device transmits a response signal, the signal confirmation device is a nurse call child. When a response signal is received from the mobile communication terminal within a predetermined time after receiving the call signal from the machine, the signal transmission device transmits the response signal to the outside, and the signal confirmation device receives the response signal within the predetermined time. When there is not, the signal transmission device transmits a call impossible signal to the outside. In the nurse call master unit, when the response signal is received, the notification unit is operated, and when the call impossible signal is received, the notification unit is operated so as to perform notification different from the case where the response signal is received. ing.

  According to the present invention configured as described above, when all the mobile communication terminals are not calling, the nurse call master performs a notification different from the calling when the mobile communication terminal is calling. Make it. As a result, even if the medical worker is in a place where the display of the nurse call master unit is not visible, if the medical worker is in a place where the call by the notification unit can be confirmed, all changes to the call from the patient due to the change of the notification It can be understood that the mobile communication terminal is not calling. Therefore, when all the mobile communication terminals are not calling, all the mobile communication terminals are not calling in response to a call from a patient by a medical worker who cannot see the nurse call master display. It is possible to increase the possibility of grasping this.

On the other hand, when the determination unit 43 determines that the base unit receiving unit 42 has received the call impossible signal, the base unit control unit 41 operates the notification unit 44 and the base unit receiving unit 42 responds. Notification different from the case where the determination unit 43 determines that a signal has been received is performed. Here, the different notification is to perform notification corresponding to the call from the nurse call slave device 10 by changing the ring tone color or increasing the ring tone.

  The notification unit 44 includes a speaker for outputting a ringing tone, a display for displaying a call, a display lamp for indicating a call by lighting or blinking, and the like. The notification unit 44 outputs a ringing sound and displays a call indication that there is a call from the nurse call slave unit 10, in other words, that the base unit receiving unit 42 has received a call signal transmitted from the nurse call slave unit 10. This is notified by lighting or blinking of the indicator lamp. The notification by the notification unit 44 is performed while the base unit receiving unit 42 receives the calling signal transmitted from the nurse call slave unit 10. When the base unit control unit 41 determines that the base unit reception unit 42 no longer receives the calling signal, the base unit control unit 41 ends the operation of the notification unit 44 and ends the notification.

  The recovery operation unit 45 is operated when a medical worker who has recognized the notification by the notification unit 44 responds to a call. Further, when the recovery operation unit 45 is operated while the notification by the notification unit 44 is being performed, the parent device control unit 41 ends the operation of the notification unit 44 and ends the notification. When the recovery operation unit 45 is operated while the notification by the notification unit 44 is being performed, the parent device control unit 41 generates a recovery signal and transmits it to the nurse call slave device 10. Here, the recovery operation unit 45 may also be used as a button or the like that is operated when a medical worker off-hooks a handset (not shown) provided in the nurse call parent device 40 in order to respond to a call from a patient. However, it may be provided separately. Further, even when a medical worker responds to a call by the mobile communication terminal 20, the parent device control unit 41 generates a recovery signal and transmits it to the nurse call child device 10.

  The master unit I / F 46 includes a slave unit I / F unit 14 and a main unit I / F unit 36 for the nurse call master unit 40 to communicate with the nurse call slave unit 10 and the handy main unit 30. It is connected to the.

  Next, the operation of the nurse call system according to the present embodiment will be described. 2 to 4 are flowcharts showing the operation of the nurse call system according to the present embodiment. As shown in the figure, the operation of the nurse call system is divided into an operation in the nurse call slave device 10, an operation in the mobile communication terminal 20, an operation in the handy main device 30, and an operation in the nurse call parent device 40. .

  In the nurse call slave unit 10, as shown in FIG. 2A, the slave unit control unit 11 determines whether or not the call operation unit 12 has been operated by the patient (step 201). If handset controller 11 determines that call operation unit 12 has not been operated by the patient (NO in step 201), the process returns to step 201 until the call operation unit 12 is operated by the patient. Continue processing. On the other hand, when slave unit control unit 11 determines that call operation unit 12 has been operated by the patient (YES in step 201), slave unit control unit 11 provides a call signal for notifying the call. Then, the slave unit transmitter 13 is operated to transmit the generated call signal to the handy main device 30 and the nurse call master unit 40 (step 202).

  The slave unit control unit 11 determines whether or not the restoration signal transmitted from the nurse call parent unit 40 has been received (step 203). If the slave unit control unit 11 determines that a recovery signal has not been received from the nurse call master unit 40 (NO in step 203), the process returns to step 202. On the other hand, if slave unit control unit 11 determines that the restoration signal has been received (YES in step 203), slave unit control unit 11 ends the generation of the call signal and transmits the call signal. End (step 204). Then, the process returns to step 201.

  In the mobile communication terminal 20, as shown in FIG. 2B, it is determined whether or not the terminal receiving unit 22 has received a call signal transmitted from the nurse call slave unit 10 via the handy main device 30. This is performed by the control unit 21 (step 211). If the terminal control unit 21 determines that the terminal receiving unit 22 has not received the call signal (NO in step 211), the process returns to step 211 and continues until the call signal is received.

On the other hand, when the signal reception unit 32 receives the calling signal (YES in step 301), the main device control unit 31 operates the timer unit 35 to measure the elapsed time (step 302). The main device control unit 31 operates the signal transmission unit 34 to transmit the received call signal to the mobile communication terminal 20 (step 303).

  The signal confirmation unit 33 determines whether or not a predetermined time has elapsed since the call signal was received (step 304). When the signal confirmation unit 33 determines that a predetermined time has elapsed since the call signal was received (YES in step 304), the main device control unit 31 ends the operation of the timer unit 35 and sets the time. Measurement is terminated, and the call impossible signal generated by operating the signal transmission unit 34 is transmitted (step 305). On the other hand, if the signal confirmation unit 33 determines that the predetermined time has not elapsed since the call signal was received (NO in step 304), the signal reception unit 32 is connected to the portable communication terminal. It is determined whether or not the response signal transmitted from 20 has been received (step 306). If signal confirmation unit 33 determines that signal reception unit 32 has not received a response signal (NO in step 306), the process returns to step 301. On the other hand, when the signal confirmation unit 33 determines that the signal reception unit 32 has received the response signal (YES in step 306), the main device control unit 31 terminates the operation of the timer unit 35 and sets the time. And the signal transmission unit 34 is operated to transmit the received response signal (step 307).

  In the nurse call parent device 40, the notification process for operating the notification unit 44 when receiving the call signal transmitted from the nurse call child device 10, the operation of the notification unit 44 is ended, and the transmission of the call signal is ended. Recovery processing for transmitting a recovery signal to the nurse call slave unit 10 is performed. In the notification process, the nurse call base unit 40 determines whether or not the base unit receiving unit 42 has received a response signal transmitted from the mobile communication terminal 20 via the handy main device 30, as shown in FIG. Is determined by the determination unit 43 (step 401). When determining unit 43 determines that base unit receiving unit 42 has received a response signal (YES in step 401), base unit control unit 41 operates notifying unit 44 and nurse call slave unit. Notification corresponding to the call from 10 is performed (step 402). On the other hand, when determining unit 43 determines that base unit receiving unit 42 has not received a response signal (NO in step 401), determining unit 43 determines that base unit receiving unit 42 is the handy main device. It is determined whether or not the call disable signal transmitted from 30 has been received (step 403). When determining unit 43 determines that base unit receiving unit 42 has not received the call disable signal (NO in step 403), the process returns to step 401. On the other hand, when determining unit 43 determines that base unit receiving unit 42 has received the call impossible signal (YES in step 403), base unit control unit 41 operates notifying unit 44 to respond. Notification different from that when the signal is received is performed (step 404). The base unit control unit 41 repeatedly executes the processes of steps 401 to 404.

  Further, the base unit control unit 41 enables the recovery process to be executed while the notification unit 44 is operating by the notification process. In the recovery process, as shown in FIG. 4B, the parent device control unit 41 determines whether or not the recovery operation unit 45 has been operated by a medical worker (step 411). If base unit control unit 41 determines that recovery operation unit 45 has not been operated by a healthcare worker (NO in step 411), the process returns to step 411, and recovery operation unit 45 is operated by the healthcare worker. Continue processing until On the other hand, if base unit control unit 41 determines that recovery operation unit 45 has been operated by a medical worker (YES in step 411), base unit control unit 41 ends the operation of notification unit 44.

  As described above in detail, in the nurse call system according to the present embodiment, when the mobile communication terminal 20 that can respond to the call signal from the nurse call slave 10 transmits a response signal, the signal confirmation unit 33 performs the nurse call. When a response signal is received from the mobile communication terminal 20 within a predetermined time after receiving the call signal from the call slave unit 10, the signal transmission unit 34 transmits the response signal to the outside, and the signal confirmation unit 33 is within the predetermined time. When the response signal is not received from the mobile communication terminal 20, the signal transmission unit 34 transmits a call impossible signal to the outside. In the nurse call parent device 40, when the response signal is received, the notification unit 44 is operated, and when the call impossible signal is received, notification different from the case where the parent device reception unit 42 receives the response signal is performed. As described above, the notification unit 44 is operated by the base unit control unit 41. Thereby, even if the medical worker is in a place where the call by the notification unit 44 can be confirmed even when the display of the nurse call parent device 40 is not visible, the medical worker can respond to the call from the patient due to the change of the notification. It can be understood that all the mobile communication terminals 20 are not calling. Therefore, when all the mobile communication terminals 20 are not calling, all the mobile communication terminals 20 are called by a medical worker who cannot see the display of the nurse call parent device 40 in response to a call from the patient. It is possible to increase the possibility of being able to grasp what has not been done.

  In the above-described embodiment, the signal reception unit 32, the signal confirmation unit 33, and the signal transmission unit 34 are provided in the handy main device 30, but are not limited thereto. For example, the signal reception unit 32, the signal confirmation unit 33, and the signal transmission unit 34 may be provided in a nurse call parent device 40 or a nurse call controller (not shown) that controls the nurse call system.

  In the above-described embodiment, when the determination unit 43 determines that the base unit receiving unit 42 has received a response signal, the notification unit 44 changes the ring tone or increases the ring tone. Thus, notification different from normal notification is performed, but the present invention is not limited to this. For example, an external buzzer is provided near the entrance of the staff room, and when the determination unit 43 determines that the master unit receiving unit 42 has received a call impossible signal, the external buzzer is activated to output a ringing tone. You may do it. Thereby, even if the medical worker is in a place where the display of the nurse call master unit 40 is not visible, if the medical worker can confirm the call by the external buzzer, the call from the patient is changed due to the change of the notification. The possibility that all the mobile communication terminals 20 can grasp that the calling operation is not performed can be further increased.

  In the above-described embodiment, when the determination unit 43 determines that the base unit receiving unit 42 has received a response signal, the notification unit 44 changes the ring tone or increases the ring tone. Thus, notification different from normal notification is performed, but the present invention is not limited to this. For example, call indicator lights are provided in various places such as a corridor, and when the receiver unit 42 determines that the call disable signal has been received, the call indicator lamp is turned on or blinked to output a call display. You may make it do.

  In the above-described embodiment, when the signal confirmation unit 33 determines that the signal reception unit 32 has not received response signals from all the mobile communication terminals 20, the handy main device 30 transmits a call impossible signal. However, it is not limited to this. For example, if the minimum number of connections between the mobile communication terminal 20 and the handy main device 30 is registered in a setting unit (not shown) and the number of response signals received by the signal receiving unit 32 is less than the preset minimum number of connections, the signal confirmation unit When the determination is made at 33, the handy main device 30 may transmit a call impossible signal. As a result, when there are few mobile communication terminals 20 that perform call operations and the medical worker carrying the mobile communication terminal 20 that performs call operations does not respond to the call, the medical worker cannot see the display of the nurse call parent device 40. However, if there is a place where the call by the notification unit 44 can be confirmed, there is a possibility that it is possible to grasp that there are few mobile communication terminals 20 performing a call operation for a call from a patient due to a change in notification. Can be high.

  In the above-described embodiment, the handy main device 30 is provided, but the present invention is not limited to this. For example, a nurse call system may be provided with a plurality of handy main devices 30.

  Specifically, when a response signal is received from at least one handy main device 30 among the plurality of handy main devices 30, the nurse call control device transmits a response signal to the nurse call parent device 40. On the other hand, when the call disable signal is received from all of the plurality of handy main devices 30, the nurse call control device transmits the call disable signal to the nurse call parent device 40. In such a case, the representative handy main device 30 may operate the nurse call controller.
