Abstract

PROBLEM TO BE SOLVED: To enable re-calling, when making a call to multiple portable terminals after receiving a call from a nurse call slave unit, even when there is a portable terminal to which the call cannot be made, in the middle of calling other portable terminals.SOLUTION: A control machine 4 includes: a call destination table storage section 41 for storing a call destination from each nurse call slave unit; and a setting time storage section 42 for storing a specific time to perform re-calling. The call destination table storage section 41 stores multiple portable terminals as call destinations with respect to each nurse call slave unit. A control machine CPU 43 continues calling of the portable terminals for a fixed time till the portable terminals respond after receiving a call operation, but when the specific time shorter than the call duration time elapses, the control machine CPU resets all calls, and then performs recalling. When there is a portable terminal to which the call cannot be made first, calling in the middle of the call duration time can be performed.

Description

  The present invention relates to a nurse call system, and more particularly, to a nurse call system in which a nurse can carry a nurse call directly to a nurse with a portable terminal.

  Nurse call systems have become widespread where nurses can carry a portable terminal and nurse calls from patients can be answered even by nurses who are not at the nurse station. In such a nurse call system, in addition to making a call using the nurse call master unit, in addition to making a call using the nurse call slave unit, a plurality of calls associated with the nurse in charge or the nurse team in charge are associated. A mobile terminal is also called and responds with either one to enable smooth correspondence (for example, see Patent Document 1).

JP 2005-349020 A

  However, when multiple call destination mobile terminals are set and the call is performed all at once, if the call destination mobile terminal is out of service area at the time of starting the call, or if communication is not possible due to communication trouble, No call signal was sent to the mobile terminal. Therefore, the mobile terminal is not called, only the other mobile terminals to be called are called as usual, a ringing tone is generated on fewer mobile terminals than the set number, and a response is waited for. became.

On the other hand, even when the paging signal is transmitted to the mobile terminal, even if the control is performed to call a plurality of mobile terminals at the same time, the controller outputs the paging signal to the exchange in the registered order, and the exchange communicates. If the communication is possible after confirming the availability, the call signal is transmitted in order. For this reason, it takes time to control the exchange, and it takes about 2 seconds to control communication with one portable terminal and transmit a call signal.
Since this time is generated by calling each mobile terminal, for example, when control is performed to call 8 mobile terminals all at once, 16 calls are made until the 8th call is completed after the first call is started. A time difference of seconds will occur. That is, when the simultaneous calling is completed, the first mobile terminal has already been ringing for 16 seconds.

  Because such call control is performed, even if control is performed to simultaneously call a plurality of mobile terminals, in practice, a specific mobile terminal always rings first, and a nurse carrying this mobile terminal There was a problem that the response was increased and the load was concentrated on a specific nurse even if the configuration was such that multiple nurses were called at once.

  Therefore, in view of such a problem, the present invention receives a call from a nurse call slave unit, and when calling a plurality of portable terminals, even if there are portable terminals that cannot be called, It is an object of the present invention to provide a nurse call system that can be added to a call from the middle of the call, and that the portable terminal that rings first is not always the same portable terminal when calling.

In order to solve the above-mentioned problems, the invention of claim 1 is a nurse call cordless handset that is installed for each bed so that a patient calls a nurse, and is installed in a nurse station and responds to a call by the nurse call cordless handset. Nurse call master device for the mobile phone, a portable terminal for carrying by a plurality of nurses to respond to the call, and a controller for controlling communication between the nurse call slave device and the nurse call master device In this system, the control unit resets call operation, a call control unit that controls calls and calls from nurse call slave units, a call destination table storage unit that stores call destinations from individual nurse call slave units, and A specific time storage unit for storing a time for performing the recall, and the call destination table storage unit is a group consisting of a plurality of portable terminals for each nurse call slave unit. The specific time stored in the specific time storage unit is set to be shorter than the call continuation time that is continued when there is no response, and the call control unit receives the nurse call handset call. Start a group of associated mobile devices, and if there is no response after a certain amount of time has passed, reset all current mobile device calls and start the call again. If there is no response from the call and the call duration time elapses, the call to the group is terminated and the process proceeds to a call for the next preset mobile terminal group.
According to this configuration, when there is a mobile terminal to be called outside the communication area at the stage when the mobile terminal is started to be called, or when there is a mobile terminal in which some communication trouble has occurred, the mobile terminal Although the terminal cannot be called, by resetting and calling again during the call, the mobile terminal that cannot be called again performs an operation for determining whether or not communication is possible. Therefore, calling can be started while calling another mobile terminal. Therefore, it is possible to reduce the occurrence of mobile terminals that cannot be called.

According to a second aspect of the present invention, in the configuration according to the first aspect, the call control unit transmits a call signal to a plurality of portable terminals in the order registered in the call destination table storage unit, and performs a call. In the case of calling again, the calling signal transmission order is changed by a predetermined procedure, and at least the portable terminal that transmits the calling signal first is changed.
According to this configuration, when a reset is performed and a recall is performed, the mobile terminal that first rings is changed by transmitting a call signal in a different order from the first call. Therefore, it is possible to reduce the bias of nurses answering calls to specific nurses.

According to a third aspect of the present invention, in the configuration according to the second aspect, the call control unit resets the call signal transmission order when the call is reset and recalled based on the order registered in the callee table storage unit. The first call signal transmission destination is changed to the last, and the second and subsequent portable terminals are sequentially moved up to perform the call.
According to this configuration, since the mobile terminal that is initially stored to transmit the calling signal is turned last when it is recalled, the nurse answering the call is biased toward a specific nurse. Can be reduced. Further, the calling signal transmission order can be changed with simple control.

According to the present invention, during a call, another mobile terminal is being called in order to determine once again whether or not communication is possible for a mobile terminal that could not be called by resetting and re-calling during the call. You can start a call from Therefore, it is possible to reduce the occurrence of mobile terminals that cannot be called.
In addition, when a call is reset and recalled, the call signals are transmitted in a different order from the first call. Therefore, the nurse responding to the call by changing the mobile terminal that rings first will change the specific nursing care It is possible to reduce the bias toward the teacher.

Reference numeral 8 denotes a LAN, and 9 denotes a HUB for connecting devices to the LAN.

  The nurse call handset 1 includes a call grip button 1a that is called by a patient and a plate handset 1b that is provided on a wall surface and includes a connection portion of the call grip button 1a and includes a microphone 11 and a speaker 12.

  The corridor lamp 2 resets the light emitting notification unit 21 that emits light to notify the surroundings when a call by the nurse call handset 1 occurs from a patient in the patient room, the patient information display unit 22 that displays patient information in the patient room, and the notification operation. A recovery button 23 and the like are provided.

  The nurse call parent device 3 displays a board-type parent device 3a having a handset 31 for responding to a call and a patient list display unit 32 displaying a list of inpatients, and detailed information and setting information of a patient. And a management personal computer 3b having the display 33.

  The controller 4 is configured as shown in FIG. 2, and a call destination table storage unit 41 that stores the call destination portable terminal 5 for each nurse call handset 1, a call control setting time such as a time for starting a retry call to be described later A set time storage unit 42 for storing the call, a call control including a retry call of the mobile terminal 5 and a controller CPU 43 for controlling the controller 4, a first communicating with the corridor lamp 2 and the nurse call master 3 via the LAN 8 A communication IF 44 and a second communication IF 45 for communicating with the exchange 6 are provided.

  The call destination table storage unit 41 associates a patient / child device table that associates the patient with the nurse call child device 1, a nurse table that associates the patient with a plurality of nurses, and associates the nurse with the portable terminal 5. A portable terminal table or the like is stored, and when a call is generated from a patient, a group of portable terminals 5 associated with the caller's nurse call cordless handset 1 is read, and as a result, a plurality of portable terminals 5 are called. Further, a plurality of groups of mobile terminals 5 are registered, and if there is no response for a predetermined time (call duration) in the first group call, the call is set to be slid to the mobile terminals 5 of other groups. .

The operation of the nurse call system configured as described above is as follows. Here, the call operation will be mainly described.
When the call grip button 1 a is pressed, a call signal is output from the plate slave unit 1 b and transmitted to the controller 4 via the corridor lamp 2. At this time, the corridor lamp 2 receives the call signal and turns on the light emission notification unit 21 to notify the occurrence of the call.

In the controller 4 that has received the call signal, the controller CPU 43 transmits the call signal to the nurse call parent device 2 and stores the portable terminal 5 associated with the nurse call child device 1 that is the call signal transmission source in the call destination table. Reading from the unit 41 and calling a plurality of portable terminals 5 belonging to the same group.
The call is executed for a preset call duration (90 seconds here), and if there is a response during that time, the call is terminated under the control of the controller CPU 43 and the response is made between the device and the caller. Is formed.

  FIG. 3 shows an example of the relationship between the nurse call slave device 1 and the portable terminal 5 stored in the callee table storage unit 41, and shows the relationship between one nurse call slave device 1 with ID “0001” and the portable terminal 5. ing. Specifically, it is shown that when the nurse call handset 1 with ID “0001” is called, four mobile terminals 5 having terminal numbers 101, 102, 103, and 104 are called. Such association is set for each of the other nurse call slave units 1, and when any of the nurse call slave units 1 is called, a plurality of portable terminals 5 are called.

Thus, when a call is generated from the nurse call cordless handset 1 with ID “0001”, the controller 4 transmits a call signal to the four mobile terminals 101, 102, 103, and 104, and the call is executed.
However, the controller 4 calls all at once, but in practice, calls are made in the order of registration. Here, call signals are transmitted to the exchange 6 in the order of 101, 102, 103, 104, and the call is executed. In response to the call signal, the exchange 6 transmits the call signal. The exchange 6 determines whether or not communication is possible with respect to the mobile terminal 5 that is the call destination, and transmits a call signal to the mobile terminal 5 that can be communicated, while performing control that does not transmit to the mobile terminal 5 that cannot communicate. To do.

  Since the call signal transmission control by the exchange 6 requires about 2 seconds per mobile terminal, when calling a plurality of mobile terminals 5, a large time difference occurs between the first call and the last call. Specifically, four mobile terminals 5 are called here, so if transmission control per one is 2 seconds, it takes 8 seconds to send a call signal to all four devices and complete the call. A call is made.

After a call is started in this way, when a preset time (specific time) elapses without being answered, a retry call is performed under the control of the controller CPU 43. Retry call is a control that once terminates the call operation and resumes the call immediately. Specifically, the specific time is 60 seconds here, and when 60 seconds have elapsed from the start of the call, the call is temporarily terminated. The call is resumed immediately.
Then, the controller CPU 43 changes the calling order at the time of retry. Specifically, in the first call, the call is performed in the order of the terminal number 101 → 102 → 103 → 104. However, at the time of retry, the terminal number 101 that has been called first is moved last, and the terminal number 102 → 103 → 104 → Calls are made in the order of 101. This call order change control is programmed in advance.

  As described above, when calling a plurality of mobile terminals 5, it takes time to complete the call. Therefore, the retry call is made so that the call duration time does not end before the call operations of all the mobile terminals 5 are completed. The start time of is set. In this example, it takes 8 seconds in total to call four mobile terminals 5, but it can be retried after 60 seconds with respect to the call duration of 90 seconds. 5 is called. Therefore, the call can be continued for 12 seconds thereafter, and a response can be waited for by all four portable terminals 5.

Thus, when there is a mobile terminal 5 to be called outside the communication area in the first call, or when the mobile terminal 5 in which some communication trouble has occurred is in the call target, the mobile terminal 5 cannot be called. However, by performing a retry call, that is, by resetting in the middle of the call and performing a recall, if the nurse carrying the mobile terminal 5 returns to the communication area, or the communication trouble is solved. If so, the call can be started from the middle of the call. Therefore, it is possible to reduce the occurrence of mobile terminals 5 that cannot be called.
Since the retry call transmits call signals in a different order from the first call, it is possible to reduce the bias of the nurse answering the call to a specific nurse.
In addition, the mobile terminal 5 that has received the last call when the recall is performed also has a retry time set for the call duration so that the ringing tone sounds for a certain period of time, and the call continues during the recall operation. It is possible to prevent a situation in which the call ends without a part of the mobile terminal to be called being called over time.
The change operation of the calling signal transmission order is a simple operation that moves up the second and subsequent calls, and the calling order can be changed with simple control.

When 90 seconds, which is the call continuation time of this group, elapses, the next group call is slid, but the above-described retry call is performed in the same manner.
Moreover, the calling order at the time of retrying is carried out in the order in which the first call in the first call is moved to the last and the second and subsequent calls are sequentially advanced. Calls may be made in order, and if the first callee is not the same, the effect is obtained.
Furthermore, the retry call is executed once during the call duration, but depending on the length of the call duration, the retry call may be executed a plurality of times. Can be prevented.
In the above embodiment, the number of mobile terminals 5 to be called is four, and the last call of the mobile terminal 5 when the retry call is made is set to be continued for 12 seconds. When looking at the case, since it takes 16 seconds to complete the call, the last call of the portable terminal 5 is performed only for 4 seconds. Since this is short, for example, in the case of 8 units, the retry call start time may be advanced by 10 seconds, for example, and started in 50 seconds.
