Description

  The present invention relates to a nurse call system, a nurse call processing method, a nurse call processing program, and a program recording medium.

  As is well known, in hospitals and welfare care facilities, etc., a nurse call system is provided for calls between patients and nurses (caregivers and caregivers in welfare care facilities and the like). The nurse call system usually has a system configuration in which a nurse call device and a private branch exchange are interlocked, and a nurse call slave unit used by a patient for calling a nurse call is provided in each bed, etc. The nurse call device is installed in the nurse station, and displays the nurse call call or calls the nurse call to the nurse call PHS terminal carried by the nurse via the private branch exchange. Nurses can make calls.

  However, in such a system configuration in which the nurse call device and the private branch exchange are interlocked, when the patient calls the nurse call by operating the nurse call slave unit, the PHS for the nurse call to be called If the terminal is not ready for incoming calls, the patient can take any action other than waiting until the nurse call PHS terminal specified as the call destination of the nurse call handset returns to a callable state. There wasn't. For this reason, the patient who has called the nurse call has been waiting for a long time before making a call with the nurse, and often has anxiety.

  Also, when the nurse call PHS terminal to be called is in an unreceivable state, the nurse call PHS terminal carried by the nurse is out of the communication range, is busy, or is turned off due to the nurse's vacation. Various cases are possible, such as, but in the worst case when the power is off or within the communication range, the nurse call PHS terminal can not be called, eventually the patient, A case occurs in which it is impossible to talk to a nurse.

  Therefore, in order to avoid the situation as described above, as described in Japanese Patent Application Laid-Open No. 2005-294930 “Nurse Call System” in Japanese Patent Application Laid-Open No. 2005-294930, the nurse call to be called for each nurse call slave unit. A countermeasure has been proposed in which not only one PHS terminal but also a plurality of nurse call PHS terminals are called simultaneously by setting and registering a plurality of PHS terminals.

Japanese Patent Laying-Open No. 2005-294930 (page 5-6)

  However, when such a countermeasure is taken, each time a certain nurse call slave makes a nurse call, the nurse call is simultaneously made to a plurality of registered nurse call PHS terminals. This will cause an unnecessary increase in communication traffic.

  In addition, when a plurality of nurse call PHS terminals are simultaneously called by a nurse call, the nurse call PHS terminal that is the original call destination of the nurse call slave that has made the nurse call call is in a state where it can receive a call. Nevertheless, the nurse call PHS terminal located far away from the nurse call PHS terminal responds first, and the nurse of the responding nurse call PHS terminal calls the nurse of the caller. There is also a problem that the situation of the patient of the Cole handset cannot be grasped, or it takes longer time to rush to the patient of the Nurse Cole handset.

  Furthermore, even if a plurality of nurse call PHS terminals are simultaneously called from the nurse call slave unit, the nurse call PHS terminal that performs a call with the nurse call slave unit is ultimately one The nurse who carries only the nurse call PHS terminal, and therefore carries the other nurse call PHS terminal that has been called at the same time, stops working to answer the nurse call call even during another work. There is also the problem of becoming inefficient.

  The present invention has been made in view of such circumstances, and makes it possible for a nurse call PHS terminal of a nurse to surely respond to a call of a nurse call from a patient's nurse call cordless hand and to make a call. A nurse call system having an escalation function for sequentially transferring a nurse call call to an alternative nurse call PHS terminal in accordance with a preset priority when a call destination nurse call PHS terminal is in an unresponsive state It is an object of the present invention to provide a nurse call processing method, a nurse call processing program, and a program recording medium.

  In order to solve the above-described problems, the nurse call system according to the present invention employs the following characteristic configuration.

  (1) A nurse call device that accepts a nurse call call from a nurse call slave unit and a private branch exchange that connects a nurse call PHS terminal that communicates with the nurse call slave unit via a wireless line operate in conjunction with each other. In this nurse call system, for each of the nurse call PHS terminals, an alternative nurse call that becomes an escalation destination when the nurse call PHS terminal does not respond to the nurse call call from the nurse call slave unit An escalation table for setting and registering a PHS terminal for use according to a predetermined priority order is provided, and the nurse call PHS terminal responds to a nurse call call from the nurse call handset within a predetermined time limit. If it is detected that there is no such call, the nurse call P By referring to the escalation table of the S terminal, the nurse call call from the nurse call handset is transferred to the alternative PHS terminal for the nurse call having a higher priority based on a predetermined priority order. A nurse call system for calling the previous PHS terminal for nurse calls.

  According to the nurse call system, nurse call processing method, nurse call processing program and program recording medium of the present invention, the following effects can be obtained.

  In the nurse call system configuration in which the nurse call device and the private branch exchange operate in conjunction with each other, the nurse call call is transferred when the nurse call PHS terminal cannot respond to the nurse call call from the nurse call slave unit. The escalation destination nurse call PHS terminal is set and registered in advance for each nurse call PHS terminal as an escalation table. Therefore, when a nurse call is called from the nurse call slave, any of the nurse call PHS terminals is registered. It is possible to call the terminal with certainty so that the caller's nurse call cordless handset and the nurse call PHS terminal can talk reliably. Thus, it is possible to respond quickly to the patient's requirements of the caller's nurse call cordless handset, and since it is possible to reliably talk to the nurse for the nurse call call, A great sense of security can be given.

  Also, in the escalation table for each nurse call PHS terminal, settings are registered so that the priority as an escalation destination is higher for the nurse call PHS terminal that is closer to the location of the target nurse call PHS terminal. Therefore, if the target nurse call PHS terminal designated in advance as a call destination for the nurse call from the nurse call slave does not respond, the alternative located near the target nurse call PHS terminal Nurse call PHS terminals can be preferentially switched as nurse call PHS terminals for escalation, and can be called one after another, nurse nurses who understand the situation of the caller nurse call slave unit A nurse call call is preferentially transferred to the call PHS terminal. To become, it is possible to respond quickly to the patient.

  Further, unlike the conventional operation of simultaneously calling a plurality of nurse call PHS terminals for one call of a nurse call from a nurse call cordless handset, the settings are registered in advance for each nurse call PHS terminal. According to the priority order, the nurse call PHS terminal of the escalation destination is sequentially called one by one, thereby freeing the nurse from the wasteful work associated with the simultaneous call and enabling an efficient operation form At the same time, it is possible to effectively use resources including the antenna.

It is a block diagram which shows the system configuration example of the nurse call system by this invention. It is a block block diagram which shows one structural example of the control part in the private branch exchange which comprises the nurse call system of this invention. It is a table block diagram which shows an example of the table structure of the escalation table in the escalation database with which the control part of the private branch exchange which comprises the nurse call system of this invention is equipped. 3 is a flowchart illustrating an example of an operation for updating an escalation table in an escalation database in the nurse call system according to the embodiment of the present invention illustrated in FIGS. 1 and 2. Escalation Service-Nurse Call Call Escalation Flow.

  Preferred embodiments of a nurse call system, a nurse call processing method, a nurse call processing program, and a program recording medium according to the present invention will be described below with reference to the accompanying drawings. In the following description, the nurse call system and the nurse call processing method according to the present invention will be described. However, the nurse call processing method may be implemented as a nurse call processing program executable by a computer, or Needless to say, the nurse call processing program may be recorded on a computer-readable recording medium.

(Features of the present invention)
Prior to the description of the embodiments of the present invention, the features of the present invention will be described first. In the present invention, a nurse call device comprising a nurse call master unit and a nurse call control unit connected to a nurse call slave unit and a private branch exchange accommodating a nurse call PHS terminal carried by a nurse are linked to each other. When a nurse call is called from the patient's nurse call cordless handset, it is detected that the call destination nurse call PHS terminal is in an unreceivable state (cannot make a call). In addition, the main feature is that the nurse call PHS terminal to be called is escalated in accordance with a predetermined priority order so that the nurse call call is automatically switched to another nurse call PHS terminal. .

(Example of the present invention)
As described above, the message communication method between the nurse call device and the private branch exchange in the nurse call system configured by linking the nurse call device and the private branch exchange is the same as that of the Interphone Industry Association and the Information and Communication Network Industries Association (CIAJ). This is realized by adopting a method conforming to “Guidelines on connection between nurse call and apartment house intercom and PBX” (established on September 25, 2002).

  In other words, generally, messages are transmitted and received between a nurse call device and a private branch exchange in accordance with the basic interface of ISDN (Integrated Service Digital Network), and are accommodated in the nurse call device. Nurse call slaves (ie, nurse call slaves attached to the patient's bed) and nurse call PHS terminals housed in the private branch exchange (ie, nurse call PHS terminals carried by nurses) It is possible to communicate in both directions, and the patient and the nurse can be in contact at any time using the nurse call cordless handset and the nurse call PHS terminal, respectively. ing.

  FIG. 1 is a block diagram showing an example of the system configuration of a nurse call system according to the present invention. It has become.

  A plurality of nurse call slaves 13a, 13b,... Are connected to the nurse call device 10, and the nurse call device 10 controls connection with the nurse call slaves 13a, 13b,. A nurse call control unit 11 in which nurse call PHS terminals to be called from the nurse call slave devices 13a, 13b,... Are set and registered in advance for each of the nurse call slave devices 13a, 13b,. , 13b,..., 13b,..., 13b,.

  On the other hand, the private branch exchange 20 is a wireless connection that transmits and receives wireless signals via a control unit 21 that controls the operation of the private branch exchange 20, an ISDN connection unit 22 that connects to the nurse call device 10, and antennas 24 a, 24 b,. The unit 23 is configured to include at least.

  Here, the private branch exchange 20 accommodates nurse call PHS terminals 25a, 25b,... For transmitting and receiving radio signals to and from the wireless connection unit 23. The exchange 20 can communicate with nurse call PHS terminals 25a, 25b,.

  The nurse call slaves 13a, 13b,... Are installed on the patient's bed, etc., and the patient presses the call button provided on the nurse call slaves 13a, 13b,. By doing this, it is possible to call the nurse by ringing the nurse call PHS terminal previously designated as the call destination among the nurse call PHS terminals 25a, 25b,... Carried by the nurse. is there.

  In other words, when the nurse call device 10 detects a nurse call call from a patient's nurse call child device 13a, for example, from the nurse call child device 13a via the nurse call parent device 12, the nurse call device 20 performs a private branch exchange 20 according to a procedure conforming to the ISDN basic interface. A connection control signal is sent to. In the connection control signal, information for designating a nurse call PHS terminal designated in advance as a call target, for example, the nurse call PHS terminal 25a, is designated.

  When the control unit 21 of the private branch exchange 20 detects the connection control signal from the nurse call device 10 via the ISDN connection unit 22, the control unit 21 analyzes the connection control signal and the nurse call PHS terminals 25a, 25b,. Among these, the call target nurse call PHS terminal 25a is determined, and an operation to call the call target nurse call PHS terminal 25a is started via the wireless connection unit 23, the antenna 24a, or the antenna 24b.

  Next, an example of the configuration of the control unit 21 of the private branch exchange 20 constituting the nurse call system of the present invention will be described with reference to FIG. FIG. 2 is a block diagram showing a configuration example of the control unit 21 in the private branch exchange 20 constituting the nurse call system of the present invention.

  As shown in FIG. 2, the control unit 21 of the private branch exchange 20 includes at least a nurse call escalation service unit 21a, an escalation timer 21b, and an escalation database 21c.

  The nurse call escalation service unit 21a activates the escalation timer 21b upon detecting that the operation for calling the call target nurse call PHS terminal is activated by the connection control signal from the nurse call device 10 under the control of the control unit 21. When the nurse call PHS terminal does not respond within the predetermined time limit (that is, when the nurse call PHS terminal has not shifted to the call state), each nurse call PHS terminal Referring to the escalation tables 21c00, 21c01,... In the escalation database 21c set and registered according to a predetermined priority order, the nurse call call is escalated to the alternative nurse call PHS terminal according to the priority order. transfer It is intended to perform an operation that. The nurse call escalation service unit 21a also performs an operation of updating the escalation tables 21c00, 21c01,... In the escalation database 21c to the latest state in response to the location registration request signal from the nurse call PHS terminal.

  The escalation timer 21b is a timer that counts the elapsed time since the call to the nurse call PHS terminal is made. When the escalation timer 21b does not shift to a call state in response to a predetermined time limit, Timeout.

  Further, as described above, the escalation database 21c is provided with escalation tables 21c00, 21c01,... For each nurse call PHS terminal, and the escalation destination for each nurse call PHS terminal is shown in FIG. Registered in association with the priority order. That is, when a nurse call call is made to each nurse call PHS terminal 25a, 25b,... (Extension numbers 100, 101,...), Respectively, There are provided escalation tables 21c00, 21c01,... For setting and registering priorities of alternative nurse call PHS terminals as transfer destinations. Note that the escalation database 21c may be constituted by, for example, a RAM (Random Access Memory) or a non-volatile flash memory.

  3 is a table configuration diagram showing an example of a table configuration of the escalation tables 21c00, 21c01,... In the escalation database 21c provided in the control unit 21 of the private branch exchange 20 constituting the nurse call system of the present invention. (A) shows the escalation table 21c00 of the nurse call PHS terminal 25a with the extension number 100, and FIG. 3 (B) shows the escalation table 21c01 of the nurse call PHS terminal 25b with the extension number 101.

  As shown in FIG. 3, each escalation table 21c00, 21c01,... In the escalation database 21c has the same format table format, and the order of the alternative nurse call PHS terminals that are escalation destinations for nurse call calls. And at least information on the antenna number 213 used when calling each alternative nurse call PHS terminal.

  For example, in the case of the escalation table 21c00 of the nurse call PHS terminal 25a having the extension number 100 in FIG. 3A, the following calling order is illustrated. If the nurse call PHS terminal 25a does not respond to the nurse call call within a predetermined time limit, the nurse call PHS terminal having the extension number 105 is called using the antenna number 1, and the extension number If the nurse call PHS terminal 105 does not respond within the time limit, the nurse call PHS terminal with the extension number 108 is called using the antenna number 2.

  When the nurse call PHS terminal with the extension number 108 does not respond within the time limit, the nurse call PHS terminal with the extension number 101 is called using the antenna number 3, and the nurse call with the extension number 101 is called. If the service PHS terminal does not respond within the time limit, the nurse call PHS terminal with the extension number 102 is called using the antenna number 3.

  Thus, when a certain nurse call PHS terminal does not respond, the nurse call call is sequentially transferred to the next alternative nurse call PHS terminal in accordance with the priority order. Even if the nurse call PHS terminal designated from 10 cannot answer and make a call, any nurse call child who has made a nurse call call in response to one of the nurse call PHS terminals responds. It is possible to talk to the machine.

  Note that the priority order may be different for each nurse call PHS terminal. For example, the priority order is assigned and registered in the order of the closest location from each nurse call PHS terminal.

  FIG. 2 illustrates the case where the private branch exchange 20 has an escalation function for sequentially escalating nurse call PHS terminals in accordance with the priority order. However, in some cases, the call is not on the private branch exchange 20 side. The apparatus 10 may be provided with the escalation function, that is, the nurse call escalation service unit 21a, the escalation timer 21b, and the escalation database 21c.

(Description of operation of the embodiment)
Next, the operation of the nurse call system according to the embodiment of the present invention described with reference to FIGS. 1 to 3 will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart showing an example of an operation for updating the escalation table in the escalation database 21c in the nurse call system according to the embodiment of the present invention shown in FIGS. 1 and 2, and the current position of the nurse call PHS terminal. An example of a mechanism in which the nurse call escalation service unit 21a that has detected the escalation updates the escalation database 21c to the latest state is described.

  When the control unit 21 receives the location registration request signal of the current location from the PHS terminal accommodated in the private branch exchange 20, the flowchart of FIG. 4 is activated, and the nurse call escalation service unit 21a first It is confirmed whether or not the PHS terminal that has transmitted the registration request signal is a nurse call PHS terminal (step S11), and if it is a nurse call PHS terminal (YES in step S11), the nurse call PHS terminal Receive location registration information about the terminal. On the other hand, if it is not a nurse call PHS terminal (NO in step S11), the process ends without performing any processing.

  When the location registration information related to the nurse call PHS terminal is received, the antenna number that transmits and receives radio waves to and from the nurse call PHS terminal indicated by the location registration information is acquired as an assigned antenna number (step S12). ). Next, the PHS terminals belonging to the acquired belonging antenna number are sequentially searched (step S13).

  When a PHS terminal belonging to the assigned antenna number is searched (YES in step S14), it is confirmed whether the searched PHS terminal is a nurse call PHS terminal (step S15), and a nurse call PHS terminal is checked. (YES in step S15), the extension number and antenna number of the nurse call PHS terminal are registered in the escalation table of the nurse call PHS terminal that has transmitted the location registration request signal in the escalation database 21c. In order, it is set and registered as a PHS terminal for nurse calls with priority in escalation order (step S16). Thereafter, the process returns to step S13, and the search operation for the next PHS terminal belonging to the assigned antenna number is repeated.

  When there is no PHS terminal belonging to the assigned antenna number (NO in step S14), the antenna number next to the assigned antenna number (that is, the nearest communication range adjacent to the communication range of the antenna of the assigned antenna number) is covered. The antenna number of the antenna is searched (step S17). If the next antenna number exists (YES in step S18), the process returns to step S13 in order to perform setting registration in the escalation table of the nurse call PHS terminal belonging to the next antenna number. repeat.

  When the above processing is repeated and the setting registration processing to the escalation table of the nurse call PHS terminal for all antennas of the private branch exchange 20 is completed (NO in step S18), the escalation table in the escalation database 21c of FIG. The update process to the latest state is terminated. As described above, the escalation table updated to the latest state relates to another nurse call PHS terminal that substitutes for the nurse call PHS terminal in order according to the priority of the escalation destination (that is, Settings are registered in a sorted state (in order of location close to the nurse call PHS terminal).

  When performing the search processing for the next antenna number in FIG. 4, as described above, the order of antennas to be searched is determined in advance based on the geographical positional relationship of the communication area (cell) of each antenna. It is good to keep. By determining the order in this way, the registration order of the alternative nurse call PHS terminals in the escalation table for each nurse call PHS terminal in the escalation database 21c, that is, the priority order indicating the escalation order becomes the target nurse call PHS. Registration is performed in the order of geographical proximity to the terminal. Therefore, the priority of escalation can be set higher for the nurse call PHS terminal that is geographically closer to the target nurse call PHS terminal that has received the nurse call call from the nurse call cordless handset. Therefore, the most preferable partner as a nurse in place of the subject nurse can make a call or rush to the patient, and the anxiety of the patient can be resolved.

  Next, an escalation operation for switching to an alternative nurse call PHS terminal and making a nurse call call when the nurse call PHS terminal that has been designated in advance by the nurse call slave unit does not respond will be described with reference to FIG. It demonstrates using the flowchart of these. FIG. 5 is a flowchart showing an example of an escalation operation in the nurse call system according to the embodiment of the present invention. The nurse call PHS terminal that is actually called by the nurse call is in a state where the call cannot be received and is predetermined. An example of a mechanism for escalating a nurse call call to an alternative nurse call PHS terminal set and registered in the escalation table of the nurse call PHS terminal when no response is made within the time limit is shown.

  The escalation timer 21b is activated when a nurse call is called from a nurse call slave to a nurse call PHS terminal designated in advance. Even if the activated escalation timer 21b counts up to a predetermined time limit, if the escalation timer 21b times out because the nurse call PHS terminal does not respond (because it does not enter the call state), The flowchart of FIG. 5 is activated.

  When the flowchart of FIG. 5 is activated, the nurse call escalation service unit 21a first refers to the escalation table of the PHS terminal for the nurse call in the escalation database 21c, and has not yet made the nurse call call as the escalation destination. Among the nurse call PHS terminals, an extension number and an antenna number of an alternative nurse call PHS terminal having the highest priority escalation rank are acquired as an escalation destination nurse call PHS terminal (step S21). ).

  Next, when the next escalation destination nurse call PHS terminal exists (YES in step S22), it is confirmed whether the next escalation destination nurse call PHS terminal is ready to receive a call ( Step S23) If the incoming call is not ready (NO in Step S23), the process returns to Step S21 to obtain the extension number and antenna number of the alternative nurse call PHS terminal in the next priority order. repeat.

  On the other hand, if the escalation destination nurse call PHS terminal is ready to receive a call (YES in step S23), the escalation destination PHS terminal designated by the nurse call slave unit is connected to the escalation destination PHS terminal. The nurse call call is transferred to the nurse call PHS terminal, and the nurse call call is made to the transfer destination nurse call PHS terminal using the antenna having the acquired antenna number (step S24). Thereafter, the escalation timer 21b is activated to shift to a state where it is monitored whether or not the nurse call PHS terminal responds within a predetermined time limit (step S25).

  As for the escalation destination nurse call PHS terminal, if the call to the nurse call is not answered within the predetermined time limit, the escalation timer 21b times out. Therefore, the flowchart of FIG. An operation of acquiring the extension number and antenna number of the alternative nurse call PHS terminal in the next priority of the alternative nurse call PHS terminal of the escalation destination that has made the call is performed.

  By performing the nurse call calling operation as described above, even if the nurse call PHS terminal specified by the nurse call slave does not answer, the nurse call call is sequentially called to the alternative nurse call PHS terminal. By escalating the operation, it becomes possible for any nurse call PHS terminal to make a call with the nurse call cordless handset of the nurse call call source, and to solve the patient requirements of the nurse call cordless handset. It is possible to resolve the patient's anxiety without fail.

(Explanation of the effect of this embodiment)
As described in detail above, according to the embodiment of the present invention, in the nurse call system configuration in which the nurse call device 10 and the private branch exchange 20 operate in conjunction with each other, the nurse call call from the nurse call slave unit is performed. If the nurse call PHS terminal fails to respond to the call, the nurse call PHS terminal to which the nurse call call is transferred is registered in advance in the escalation table for each nurse call PHS terminal in the escalation database 21c. Therefore, when a nurse call is called from the nurse call cordless handset, one of the nurse call PHS terminals is surely called, and the caller's nurse call cordless handset and the nurse call PHS terminal are surely called. It is possible to make a call. Thus, it is possible to respond quickly to the patient's requirements of the caller's nurse call cordless handset, and since it is possible to reliably talk to the nurse for the nurse call call, A great sense of security can be given.

  Also, in the escalation table for each nurse call PHS terminal in the escalation database 21c, the priority level as the escalation destination is higher for the nurse call PHS terminal that is in a location closer to the target nurse call PHS terminal. If the target nurse call PHS terminal designated in advance as a nurse call destination from the nurse call slave does not respond, it is located near the target nurse call PHS terminal. As an alternative nurse call PHS terminal, it is possible to call the nurse call PHS terminal with priority as an escalation destination nurse call PHS terminal, and understand the situation of the patient of the caller's nurse call slave. Excellent for nurse call PHS terminals To result in the nurse call call is forwarded, it is possible to respond quickly to the patient.

  Further, unlike the conventional operation of simultaneously calling a plurality of nurse call PHS terminals for one call of a nurse call from a nurse call cordless handset, the settings are registered in advance for each nurse call PHS terminal. According to the priority order, the nurse call PHS terminal of the escalation destination is sequentially called one by one, thereby freeing the nurse from the wasteful work associated with the simultaneous call and enabling an efficient operation form At the same time, it is possible to effectively use resources including the antenna.

The configuration of the preferred embodiment of the present invention has been described above. However, it should be noted that such examples are merely illustrative of the invention and do not limit the invention in any way.
