Description

  The present invention relates to a nurse call system, and more particularly, to a nurse call system that can efficiently call a portable terminal carried by a nurse or a care worker.

  Conventionally, a nurse call system of this type is known as shown in FIG.

  In the figure, the conventional nurse call system is installed for each patient room, such as the child devices 10a, 10b,... Through the corridor lamps 20a, 20b,... And the corridor lamps 20a, 20b,. A control unit 30 that controls various information and secures a communication path when the nurse call is transmitted, and a parent unit 40 that talks with a patient who has received a nurse call from a slave unit by a nurse or a care worker. In response to the nurse call notification from the controller 30, the nurse or nursing care worker individually carries the first to fourth portable terminals 50a, 50b, 50c, 50d via the radio base station 70. And Le, those comprising a switch 60 for securing the communication path is known. Here, the controller 30 includes a controller / exchanger communication unit 30a, and the controller 30 is connected to the corridor lamps 20a, 20b,... Via the first transmission line L10, and to the second transmission line L20. Are connected to the main unit 40 via the third transmission line L30 and to the exchange 60, respectively, and each corridor lamp 20a, 20b,... Corresponds to the sub unit 10a via the fourth transmission line L40. Are connected to the exchange 60 via the fifth transmission line L50 (see, for example, Patent Document 1).

  In the nurse call system having such a configuration, when a nurse or the like does not respond to a nurse call from a patient, the nurse call order of the mobile terminal is changed at regular intervals, and the nurse call is sequentially added to the registered mobile terminals. It is configured to make a call. Here, “nurse call” means that a patient calls a nurse or a care worker at a hospital or a care facility to make a call.

  FIG. 5 is a flowchart showing a call transition state of the mobile terminal during a nurse call.

  4 and 5, for example, a certain patient (hereinafter referred to as “patient A”) is installed on the patient A's bed and connected to a corridor lamp 20a (hereinafter referred to as “first corridor lamp 20a”). When a call button (not shown) of the child device 10a (hereinafter referred to as “first child device 10a”) is pressed, a call activation signal is sent to the first corridor lamp 20a via the fourth transmission line L40. When such a call activation signal is detected by the first corridor lamp 20a, a call indicator lamp (not shown) of the first corridor lamp 20a blinks. At the same time, a call signal containing room number information, call type information, and bed number information pre-assigned to the first hall light 20a is sent from the first hall light 20a via the first transmission line L10. Is transmitted to the controller 30 (first call event C10).

  When such a call signal is detected by the controller 30, a call control signal containing room number information and call type information is transmitted from the controller 30 to the parent device 40 via the second transmission line L20. In this manner, the extraction processing of the mobile terminal that is the first call target is performed (first existing function event EF10). That is, in the first existing function event EF10, it is determined which nursing support team the patient A belongs to using the room number information and the bed number constituting the calling signal as keys, and the nursing support team of the patient A is extracted. Then, a mobile terminal number table (not shown) set for each nursing support team is referred to, and it is determined which mobile terminal should be nurse-called for the first time. In this example, the first and second portable terminals 50a and 50b are set as the first call target, and the third and fourth portable terminals 50c and 50d are set as the second call target.

  Then, in the first existing function extraction event EF10, when the first and second portable terminals 50a and 50b to be called for the first time are extracted, the controller 30 outputs the first and second portable terminals. Call data for calling 50a and 50b (hereinafter referred to as "first call data") is output, and the first call data is exchanged via the controller / exchanger communication unit 30a and the third transmission line L30. 60 (second and third call events C20, C30). The first call data received by the exchange 60 is wirelessly transmitted to the first and second portable terminals 50a and 50b as signal-converted radio signals (fourth call event C40). In addition, the controller 30 starts a timer at the time when the first call data is transmitted in the second call event C20.

  Here, if there is no response from the first and second portable terminals 50a and 50b even after the time (about 20 seconds) set for each system has elapsed in advance, the second to fourth call events C20, Connections at C30 and C40 are disconnected (first to third disconnection events S10, S20, and S30), and extraction processing of the third and fourth portable terminals 50c and 50d that are the second call target is performed. (Second existing function extraction event EF20).

  The second existing function extraction event EF20 and later are processed in the same manner as the first existing function extraction event EF10 and later. That is, when the third and fourth portable terminals 50c and 50d that are the second call target are extracted in the second existing function extraction event EF20, the third and fourth portable terminals 50c and 50d are called. Call data (hereinafter referred to as "second call data") is sent to the exchange 60 via the controller / exchanger communication unit 30a and the third transmission line L30 (fifth and sixth call events C50, C60), the second call data received by the exchange 60 is wirelessly transmitted to the third and fourth portable terminals 50c, 50d as signal-converted radio signals (seventh call event C70). In addition, the controller 30 starts a timer at the time when the second call data is transmitted in the fifth call event C50.

  As described above, in the conventional nurse call system, even if the nurse who possesses the first and second portable terminals 50a and 50b cannot respond by repeating the flow as described above, a predetermined time is passed. Other nurses possessing the third and fourth portable terminals 50c and 50d can make a proxy response after the passage.

  However, in the nurse call system having the conventional configuration, if the power of the first and second portable terminals 50a and 50b that are the first call target is turned off or malfunctions, Therefore, there is a problem in that it is impossible to make a nurse call to the third and fourth portable terminals 50c and 50d unless a certain period of time elapses. Therefore, in the conventional nurse call system, when the nurse who calls the first time is the main charge and the nurse who calls the second time or more is the sub-charge, the main portable terminal becomes unusable. In such a case, the mobile terminal of the secondary nurse cannot be called until a certain period of time has elapsed, and as a result, there is a possibility that prompt care for the patient becomes difficult.

JP 2003-295018 A (paragraph number “0012”, FIG. 1)

  The present invention has been made to solve the above-described problems, and even when the power of the mobile terminal is turned off or the mobile terminal is broken, it can be called to another mobile terminal without waiting for a certain period of time. The purpose is to provide a nurse call system that can be used.

  The nurse call system according to the first aspect of the present invention is a slave unit that is installed for each hospital bed such as a hospital and a nursing facility, and a patient calls a nurse or a care worker, and is installed for each patient room. A corridor lamp that displays a nurse call, a controller that controls various information and secures a communication path when a nurse call is transmitted from the slave unit via the corridor lamp, and a nurse or a care worker is a nurse call from the slave unit Switch that receives the nurse call notification from the master unit and the control unit, and makes a nurse call to the mobile terminal that is individually carried by the nurse or care worker and secures the communication path If the nurse or care worker does not respond to the nurse call from the patient, the nurse call order of the mobile terminal is changed at regular intervals and nurses are sequentially registered on the registered mobile terminals. The nurse does not wait for a certain time due to the absence notification event from the exchange when the mobile terminal that made the first call is in an unusable state due to power off or failure, etc. A nurse call to another mobile terminal.

  According to a second aspect of the present invention, in the nurse call system according to the first aspect, the controller receives the absence confirmation means to which an absence notification event is input and the absence confirmation means from the absence confirmation means. And telephone number changing means for setting another mobile terminal number to be used for the next nurse call at the time.

  According to a third aspect of the present invention, in the nurse call system according to the first aspect, the controller acquires the absence notification event based on the setting information for each switch set for each model of the switch.

According to the nurse call system of the first aspect to the third aspect of the present invention,
When the mobile terminal that made the first nurse call is in an unusable situation due to power-off or malfunction, an absence notification event is issued from the exchange, so it does not wait for a certain period of time and is sent to another mobile terminal. You can make a nurse call. Therefore, according to the nurse call system of the present invention, it is possible to respond faster when a patient calls, and to form a detailed nursing support team.

  Hereinafter, a preferred embodiment to which the nurse call system of the present invention is applied will be described in detail with reference to the drawings.

  FIG. 1 shows a system configuration diagram of the nurse call system of the present invention. In the same figure, the nurse call system of the present invention is installed in each hospital bed such as a hospital and a nursing facility, and the slaves 1a, 1b,... The corridor lamps 2a, 2b,... That are installed and display nurse calls from the slave units 1a, 1b,... And the corridor lamps 2a, 2b,. The control unit 3 that controls various information and secures the communication path when the nurse call is transmitted, and the master unit 4 that talks with the patient who the nurse or care worker receives the nurse call from the slave unit and receives the nurse call. The nurse call notification from the controller 3 is received, and the nurse or care worker is individually carried to the first to fourth portable terminals 5a, 5b, 5c, and 5d via the radio base station 7. Exchange 6 that calls and secures the communication path It is equipped with a. Here, the controller 3 passes through the first transmission path L1 to the corridor lamps 2a, 2b,..., Passes through the second transmission path L2 to the master unit 4, and passes through the third transmission path L3. Each of the corridor lamps 2a, 2b,... Is connected to a corresponding slave unit 1a, 1b,... Via a fourth transmission line L4. A radio base station 7 is connected via a transmission line L5.

  The controller 3 includes a controller main (not shown) and a controller / exchanger communication unit 3a. The controller / exchanger communication unit 3a stores the absence confirmation means ACM shown in FIG. Stores the telephone number changing means PNC shown in FIG. 2b. Here, as shown in FIG. 2A, the absence confirmation means ACM stores setting information ACMe for each exchange set for each model of the exchange 6, and the telephone number change means PNC stores FIG. The change method setting information PNCc is stored as shown in FIG.

  Next, the operation of the nurse call system of the present invention configured as described above will be described with reference to the flowchart of FIG.

  In FIG. 1 and FIG. 3, for example, a patient (hereinafter referred to as “patient a”) is installed on the patient's bed and connected to a corridor lamp 2a (hereinafter referred to as “first corridor lamp 2a”). When a call button (not shown) of the child device 1a (hereinafter referred to as “first child device 1a”) is pressed, the first and second portable terminals 5a and 5b are called. It is the same. That is, when the call button of the first handset 1a of the patient a is pressed, a call activation signal is sent to the first corridor lamp 2a via the fourth transmission line L4. When detected by the corridor lamp 2a, a call indicator lamp (not shown) of the first corridor lamp 2a blinks. At the same time, a call signal containing room number information, call type information, and bed number information pre-assigned to the first hall light 2a is sent from the first hall light 2a via the first transmission line L1. And transmitted to the controller 3 (first call event C1).

  When such a call signal is detected by the controller 3, a call control signal containing room number information and call type information is transmitted from the controller 3 to the parent device 4 via the second transmission line L2, and In this manner, the extraction processing of the mobile terminal that is the first call target is performed (first existing function event EF1). That is, in the first existing function event EF1, it is determined which nursing support team the patient a belongs to using the room number information and the bed number constituting the calling signal as a key, and the nursing support team of the patient a is extracted. Then, a mobile terminal number table (not shown) set for each nursing support team is referred to, and it is determined which mobile terminal should be nurse-called for the first time. In this embodiment, the first and second portable terminals 5a and 5b are set as the first call target, and the third and fourth portable terminals 5c and 5d are set as the second call target.

  Then, in the first existing function extraction event EF1, when the first and second portable terminals 5a and 5b to be called for the first time are extracted, the first and second portable terminals are extracted from the controller 3. Call data for calling 5a and 5b (hereinafter referred to as "first call data") is output, and the first call data is exchanged via the controller / switch communication unit 3a and the third transmission line L3. 6 (second and third call events C2, C3). The first call data received by the exchange 6 is wirelessly transmitted to the first and second portable terminals 5a and 5b as signal-converted radio signals (fourth call event C4). Further, the controller 3 starts a timer at the time when the first call data is transmitted in the second call event C2.

  Here, when the power of the first and second mobile terminals 5a and 5b is turned off or when the mobile terminal is out of order, in the exchange 6, the mobile terminal is turned off or the mobile terminal is in a failed state. And the first absence notification event AN1 indicating the absence of the portable terminal is output from the exchange 4, and the first absence notification event AN1 is transmitted to the controller / exchanger communication unit 3a via the third transmission line L3. Sent out.

  When the first absence notification event AN1 is detected by the controller / exchanger communication unit 3a, as shown in FIG. 2A, the absence confirmation unit ACM enters the absence mode process. That is, when the first absence notification event AN1 is received by the absence information receiving unit ACMa, the absence information inquiry unit ACMC confirms whether or not the received first absence notification event AN1 is a normal absence notification. Then, in the exchange-specific setting information confirmation unit ACMb, the exchange method currently used is acquired from the exchange-specific setting information ACMe. Here, there are two types of switching systems, the Direct system and the Quarry system. The former system is a system that receives data received from the switching system as it is and transfers the data, and the latter system is a method for transferring the mobile terminal to the switching system again. This is a method for transferring data when the mobile terminal is unavailable due to a status inquiry. In this way, by including the exchange system in the exchange-specific setting information ACMe, the processing can be easily changed in accordance with the exchange situation and system situation.

  That is, in the absence information inquiry unit ACMC, when the data is normal and the Direct method is acquired from the setting information ACMe by switch, the second absence notification event AN2 is immediately created in the absence information transmission unit ACMed, and the controller 2 is sent to the main controller (not shown). On the other hand, when the QUARY method is acquired, when the mobile terminal status inquiry is performed again and the mobile terminal is disabled, the second absence notification event AN2 is created in the absence information transmitting unit ACMd. And transmitted to the main controller of the controller 2. Here, when “no setting” is acquired in the switch-specific setting information ACMe, the absence notification event as described above is not created, and as a result, the processing is the same as that of the conventional nurse call system.

  Next, when the second absence notification event AN2 is sent from the controller / exchanger communication unit 3a to the main controller of the controller 3, the timer is reset and, as shown in FIG. An emergency mobile terminal number is determined by the number changing means PNC. That is, when the second absence notification event AN2 is received by the telephone number changing unit PNC, an access signal is sent from the change method inquiry unit PNCa to the change method setting information PNCc, and either “next slide information” or “fixed” That method is acquired.

  Here, the method of “next slide information” is a method of acquiring the next information of the conventional slide information, and when the second call event C2 of the nurse call is the first call, the second call information is obtained. The target third and fourth portable terminals 5c and 5d are acquired, and a fifth call event C5 is sent to the controller / exchanger communication unit 3a. In the “fixed” method, the fifth call event C5 is used for communication between the controller and the exchange, with the mobile terminals (third and fourth mobile terminals 5c and 5d) set in advance separately regardless of the number of times. Sent to the unit 3a.

  When the fifth call event C5 is sent to the controller / exchanger communication unit 3a, a sixth call event C6 is sent from the controller / exchanger communication unit 3a to the switch 6 via the third transmission line L3. A call is made from the exchange 6 to the mobile terminals (third and fourth mobile terminals 5c and 5d) to be newly called (seventh call event C7). Then, in the seventh call event C7, the third and fourth portable terminals 5c and 5d are extracted, and the substitute portable terminals (third and fourth portable terminals 5c and 5d) are nurse-called. Then, an immediate proxy call is made to the nurse or the like who possesses the third and fourth portable terminals 5c and 5d. Further, the controller 3 starts a timer when the fifth call event C5 is sent.

  The nurse call system of the present invention is not limited to the above-described embodiment. For example, the same effects as the nurse call system of the present invention can be obtained as described below.

  First, in the above-described embodiment, a nurse responds to a nurse call from a patient, but a care worker may also respond.

  Secondly, in the above-described embodiment, the number of calls of the portable terminal is set to two at the first time and the second time. However, one or three or more portable terminals may be called.

  Thirdly, in the above-described embodiment, the absence notification event occurs only when all the mobile terminals that have called cannot respond, but when at least one of the calling terminals cannot respond (power OFF, etc.) A notification event may be generated to recall only the number that was absent.

  Fourth, the number of slave units, hallway lights, and portable terminals can be increased or decreased according to the scale of the system.
