  In the above-described conventional nurse call system connected to a LAN, when a mobile terminal responds to a call from the nurse call slave, communication between the nurse call slave and the mobile terminal is performed by peer-to-peer. In this case, even if a new call occurs from another nurse call slave during a call, the nurse who is answering on the mobile terminal generates a new call because an interrupt signal could not be sent and notified. There was a problem that could not be recognized.

  Therefore, in view of such a problem, the present invention provides a mobile terminal that responds to a call on a peer-to-peer basis. The purpose is to provide a recognizable nurse call system.

  In order to solve the above problems, the invention of claim 1 is directed to a nurse call slave set installed for each bed for a patient to call a nurse, a call signal from the nurse call slave set and a call generation. A corridor lamp that operates at the entrance to the hospital room, a nurse call master unit for responding to calls from patients, a controller that controls communication between devices, and a nurse carrying it to call from the nurse call slave unit A nurse call system comprising a portable terminal for responding and having a corridor lamp, a nurse call master unit, and a controller connected by a LAN, and a call signal transmitted from the nurse call slave unit to the portable terminal Is transmitted through the controller, while the call signal between the nurse call handset and the mobile terminal is carried out peer-to-peer, and the controller can send a new call to the mobile terminal While having a call generation notification unit that transmits a notification signal to the portable call terminal and the nurse call slave unit that is forming a communication path, either the nurse call slave unit or the corridor lamp receives a notification signal when the notification signal is received And a notification sound transmission unit that interrupts the generated notification sound into the call sound and transmits it to the mobile terminal of the call destination. When a call to a nurse call cordless handset occurs, the call occurrence notification unit sends a notification signal to the nurse call cordless handset that is forming the communication path, and the notification sound generation unit that receives the notification signal generates the notification sound The received notification sound is interrupted in the call sound and transmitted to the mobile terminal of the call destination.

  According to the present invention, even if a call signal transmission destination portable terminal of a nurse call slave unit that has been operated for a call is in a peer-to-peer call with another nurse call slave unit, Notification sound is transmitted to the mobile terminal. Therefore, even if a call is made on a peer-to-peer basis, the nurse who is talking can recognize that a new call has occurred, and can smoothly respond to a patient waiting for a response.

And a management personal computer 3b to which the display 33 is connected.

  The controller 4 is configured as shown in the circuit block diagram of FIG. 3, and includes a call destination table storage unit 41 that stores a call destination mobile terminal 5 for each nurse call handset 1, and a talk that stores the mobile terminal 5 during a call. Middle terminal storage unit 42, controller CPU 43 that performs call control and control controller 4, first communication IF 44 that communicates with corridor lamp 2 and nurse call master unit 3 via LAN 8, and second communication that communicates with exchange 6 IF45 etc. are provided.

The operation of the nurse call system configured as described above will be described below. However, the call operation will be mainly described.
When the call grip button 1a of one of the nurse call slave units (hereinafter referred to as "first slave unit") 1 is called in a standby state without a call, the plate slave unit 1b of the first slave unit 1 is called. A call signal is sent to the corridor lamp 2. The corridor lamp 2 that has received the call signal transmits a call signal to which the handset ID, the corridor lamp ID, and the like are assigned to the controller 4 via the HUB 9.
The controller 4 that has received this call signal transmits the call signal to the nurse call parent device 3 and the portable terminal 5 under the control of the controller CPU 43. In order to call the mobile terminal 5, the mobile terminal 5 associated with the first handset 1 is read from the call destination table storage unit 41 and a call signal is transmitted to the mobile terminal 5.
The calling signal is transmitted to the exchange 6 and is transmitted from the exchange 6 to the mobile terminal 5 via the base station 7. Thus, the ringing tone is reported by the nurse call parent device 3 and the portable terminal 5.

When the nurse who recognizes the occurrence of the call by the ringing sound performs a response operation on the portable terminal 5, a response signal is transmitted to the controller 4 via the exchange 6. Upon receiving the response signal, the control device 4 is connected to the mobile terminal 5 and the first handset 1 via the exchange 6 via the exchange 6 under the control of the control device CPU 43 and can talk. At this time, the controller CPU 43 stores in the busy terminal storage unit 42 the information of the mobile terminal 5 that is busy.
In this way, the calling signal is transmitted to the portable terminal 5 via the controller 4, but after the response operation, the first slave unit 1 and the portable terminal 5 are connected via peer-to-peer via the LAN 8 and not via the controller 4. A call is made.

In this state, when a call is generated from another nurse call handset (hereinafter referred to as “second handset”) 1 associated with the mobile terminal 5 that is in a call, the mobile terminal 5 that is currently responding is called. The following control is performed.
The call signal transmitted from the second slave unit 1 is received by the controller 4 through the same route as described above. The control unit CPU 43 that has received this call signal grasps the portable terminal 5 that transmits the call signal from the information in the call destination table storage unit 41, but at the same time, the portable terminal 5 is in a call with the first slave unit 1. Is recognized from the information in the busy terminal storage unit 42. As a result, the controller CPU 43 generates a notification signal for notifying that a call has been received from the second slave unit 1 and transmits the notification signal to the first slave unit 1.

  Since the mobile terminal 5 and the first slave unit 1 are connected by peer-to-peer, the controller 4 transmits a notification sound informing the responding mobile terminal 5 that a new call has occurred. I can't.

  In the first handset 1 that has received the notification signal, the notification sound generation unit 15 creates a notification sound such as “beep” under the control of the handset CPU 17, and the handset CPU 17 sends a sound to the mobile terminal 5 that is the call destination. Send a notification sound in the signal. This notification sound is transmitted together with the transmitted voice signal to the portable terminal 5 through the corridor lamp 2, the HUB 9, the exchange 6, and the base station 7, and “beep” or the like is transmitted in the portable terminal 5 during a call with the first slave unit 1. A notification sound flows. Thus, the nurse can recognize that a new call has occurred during a call with the first slave unit 1.

  As described above, even if the call signal transmission destination portable terminal 5 of the nurse call slave device 1 that has been operated for a call is in a peer-to-peer call with another nurse call slave device 1, the interrupt signal is transmitted. A notification sound is transmitted from the nurse call handset 1 during a call to the mobile terminal 5 that is the call destination. Therefore, even if a call is made on a peer-to-peer basis, the nurse who is talking can recognize that a new call has occurred, and can smoothly respond to a patient waiting for a response.

  In the above embodiment, the notification sound generator 15 is provided in the nurse call slave device 1 so that the notification sound is transmitted from the nurse call slave device 1 to the mobile terminal 5 that is the call destination. The notification sound generator 15 may be provided in the corridor lamp 2 to transmit the notification sound from the corridor lamp 2 to the portable terminal 5. If it is provided in the corridor lamp 2, it is not necessary to provide it in each nurse call cordless handset 1, so that the circuit can be reduced.
