Description

  The present invention relates to a nurse call system, a nurse call control method, and a nurse call control program, and in particular, a nurse call system using a local PHS (Personal Handy-phone System) terminal as a nurse call communication terminal carried by each nurse, The present invention relates to a call control method and a nurse call control program.

  Conventionally, as described in, for example, Japanese Patent Application Laid-Open No. 2005-349020 “Nurse Call System” of Patent Document 1, a patient who is admitted to a medical institution including a hospital or the like has a nurse call child in an emergency. There is a nurse call system in which nurses are used to make nurse calls. By the nurse call, the receiving terminals (portable terminals) carried by a plurality of nurses who form the nursing team of the patient are called all at once via the nurse call master unit. Each receiving terminal (mobile terminal) of the nurses to be called is generally composed of a private handy-phone system (PHS) terminal accommodated in the private branch exchange. When any of the receiving terminals responds, a call can be made between the responding receiving terminal and the nurse call cordless handset of the patient who made the nurse call, and calling of the other receiving terminals that did not respond is stopped.

Japanese Patent Laying-Open No. 2005-349020 (page 6-7)

  However, in the conventional nurse call system as described above, it is necessary to repeat the operation of calling all nurses at once for each nurse call. When a nurse call is made almost simultaneously, each nurse is carrying the action to call all the nurses who have teamed up first for a patient's nurse call. Since all of the local PHS terminals have been transferred to the called state, any one of the called local PHS terminals responds to the call state with the patient, and all other unresponsive Until the operation during the call of the local PHS terminal is temporarily stopped, the call operation cannot be performed for the nurse call of another patient, It has been in wait state.

  When one of the local PHS terminals responds to the first call and the call operation of the other local PHS terminals is stopped, the nurse call parent device side of each of the nurse calls in the waiting state With respect to the next nurse call, all the nurses in the team carry out an operation to call all the PHS terminals carried by the nurses all at once.

  Therefore, when a plurality of nurse calls are accepted almost simultaneously, it takes time to call the nurse's local PHS terminal for each nurse call, and until the local PHS terminal responds to each call. It takes time, and there is a problem that nurses' responses to the accepted nurse call are delayed.

  The PHS system has a mechanism for calling a local PHS terminal for each calling area number indicating the physical location of the local PHS base station. Therefore, even when a plurality of nurse calls occur almost simultaneously, for each calling area number, the nurse's local PHS terminals located from the plurality of local PHS base stations in each calling area are almost Can be called at the same time. Further, even when a plurality of nurse PHS terminals are located in the wireless communication areas of a plurality of local PHS base stations belonging to the same calling area number, a plurality of local areas within the same calling area can be accessed from the private branch exchange. It is also possible to transmit a call instruction signal to each local PHS terminal located in the area to all the PHS base stations almost simultaneously.

  However, since it is a standard that can send a call signal to only two local PHS terminals in a minimum of 2.4 seconds on the radio line from the local PHS base station, If the number of on-premise PHS terminals of such nurses increases, it will be necessary to wait for the call signal to be transmitted on the radio line from the on-site PHS base station within the on-site PHS base station. It takes time to call the teacher's premises PHS terminal.

  In addition, when a plurality of nurse calls occur, it is necessary to repeat the call operation once for each nurse call. Therefore, the call operation of the local PHS terminal by one nurse call and the call operation by the next nurse call During this period, other PHS terminals that are not related to the nurse call from the patient may be in a call state using the call channel of the local PHS base station used for the nurse call. Even if an attempt is made to call the local PHS terminal by the nurse call of the local PHS terminal, the communication channel of the local PHS base station that can be used for the call of the local PHS terminal is not available, and the local PHS terminal by the next nurse call Occasionally, it becomes impossible to make a call.

(Object of the present invention)
The present invention has been made in view of such circumstances, and when a local PHS terminal is used as a receiving terminal for nurses who call by a nurse call from a patient, a nurse call is generated from a plurality of patients almost simultaneously. It is an object of the present invention to provide a nurse call system, a nurse call control method, and a nurse call control program capable of shortening the time required to call each nurse's premises PHS terminal by a nurse call. It is said.

  In order to solve the above-described problems, the nurse call system, the nurse call control method, and the nurse call control program according to the present invention mainly adopt the following characteristic configuration.

  (1) The nurse call system according to the present invention receives a nurse call from a nurse call slave of a hospitalized patient, and calls a local PHS (Personal Handy-phone System) terminal carried by each nurse. In the nurse call system to be performed, when a nurse call is generated almost simultaneously from the plurality of nurse call slaves, the call operation for each local PHS terminal by the first nurse call is continued, and the call operation is continued as it is. A simultaneous paging operation by a plurality of nurse calls is performed in which each of the local PHS terminals is further notified that a subsequent nurse call is occurring.

  (2) The nurse call control method according to the present invention accepts a nurse call from a nurse call slave of a hospitalized patient and calls it to a local PHS (Personal Handy-phone System) terminal carried by each nurse. When a nurse call is generated almost simultaneously from a plurality of the nurse call slaves, the call operation is continued as it is after the call operation to each local PHS terminal by the first nurse call. In this state, a simultaneous call operation by a plurality of nurse calls is performed in which each of the local PHS terminals is further notified that a subsequent nurse call has occurred.

  (3) The nurse call control program according to the present invention is characterized in that at least the nurse call control method described in (2) is implemented as a program executable by a computer.

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

  First, even when a plurality of nurse calls from a plurality of nurse calls are generated almost simultaneously, the first nurse call is performed once without waiting for a response to a call to each nurse's premises PHS terminal. By performing the simultaneous call operation with multiple nurse calls only by the call operation of each nurse, it is possible to continuously call each nurse's premises PHS terminal by the subsequent nurse call to the simultaneous call state by multiple nurse calls. Since the transition can be made, it becomes possible to make a call in response to each nurse call in a short time.

  Secondly, when a plurality of nurse calls are generated almost simultaneously from a plurality of nurse call slaves, until the nurse PHS terminal responds to the call by all nurse calls, and transitions to a call state, Since the call operation to the local PHS terminal is not stopped by continuing to use the communication channel of the local PHS base station used for the nurse call, the nurse performs the simultaneous call operation by a plurality of nurse calls. The call channel of the local PHS base station used for the nurse call is interrupted by another call that is not related to the call by the call, and the call channel for the nurse call is lost. It is possible to completely prevent the situation where the calling operation cannot be performed.

It is a system configuration figure showing an example of the system configuration of the nurse call system of the present invention. FIG. 3 is a sequence diagram for explaining an example of an operation when a call operation is performed from a plurality of nurse call slaves in the same time period in the nurse call system shown in FIG. 1 as an example of the present invention.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a nurse call system, a nurse call control method, and a nurse call control program according to the present invention will be described with reference to the accompanying drawings. In the following description, the nurse call system and the nurse call control method according to the present invention will be described. However, the nurse call control method may be implemented as a nurse call control program executable by a computer, or Needless to say, the nurse call control 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, an outline of the features of the present invention will be described first. In the present invention, a nurse who is accommodated in a private branch exchange connected to a nurse call master unit by a patient who is admitted to a medical institution including a hospital or the like makes a nurse call using a nurse call slave unit in an emergency. In a nurse call system for calling a wireless terminal (such as a local PHS terminal) to be carried, when a nurse call from a plurality of nurse call slaves occurs in the same time period, a nurse or the like who is the object of multiple calls is carried By notifying each receiving terminal (such as a local PHS terminal) that a plurality of nurse calls are occurring almost simultaneously, the nurse of each receiving terminal (such as a local PHS terminal) can respond in a short time. The main feature is that it has a possible mechanism.

  In other words, in a medical facility such as a hospital that accommodates a wireless terminal (private PHS terminal) carried by each nurse as an extension, a hospitalized patient presses the call button on the nurse call handset and presses the nurse call. When a nurse call system that simultaneously calls a wireless terminal (premise PHS terminal) carried by each nurse via a wireless line and a plurality of nurse calls occur almost simultaneously, By displaying the information (room number, bed information, etc.) on all the patients who have made a nurse call on the display of each nurse's wireless terminal (internal PHS terminal) simultaneously or alternately, The main feature is that each nurse recognizes that nurse calls occur almost simultaneously. Each nurse is it possible to carry out the motivation to respond in a short period of time.

  More specifically, the present invention has the following mechanism. In other words, when a plurality of patients admitted to a medical facility such as a hospital make a nurse call using each nurse call cordless handset at the same time, the nurse call of one of the patients as the first nurse call, The first call to the local PHS terminal carried by each nurse who forms a team to perform nursing of the patient by calling operation to notify the nurse call slave information (room number, bed number, etc.) of the patient Regardless of whether any of the local PHS terminals responds to the initial call or not, whether the call to the local PHS terminal of each nurse is maintained or not. The main feature is that it performs a call operation that sequentially notifies the nurse call slave unit information (room number, bed number, etc.), and thus it is necessary to call each nurse call. Response time for calls is greatly reduced by making each nurse recognize that nurse calls are occurring in the same time zone from multiple nurse call slave units and motivating them to respond quickly. Can be shortened.

  Here, when notifying the information on the nurse call slave unit (room number, bed number, etc.) to the local PHS terminal in the calling state, as described above, the information on the notified nurse call slave unit (room number) , Bed number, etc.) may be notified as a signal to be displayed on the local PHS terminal. In addition, in order for each nurse to recognize that a nurse call is generated from a plurality of nurse call slave units in the same time zone when a nurse call is generated from a plurality of nurse call slave units, You may make it call the local PHS terminal of each nurse using the special ringtone which shows that.

(Description of operation of embodiment)
Next, as an example of the operation of the nurse call system shown in FIG. 1, an example of the operation when a plurality of nurse call units 107a, 107b,... This will be described in detail with reference to the sequence diagram. FIG. 2 is a diagram for explaining an example of an operation when a call operation is performed from a plurality of nurse call slaves 107a, 107b,... In the same time period in the nurse call system shown in FIG. It is a sequence diagram. FIG. 3 is a sequence diagram for explaining the operation when a call operation is performed from a plurality of nurse call slaves in the same time zone in the conventional nurse call system.

  In order to facilitate the explanation of the features of the operation of the sequence diagram of FIG. 2 showing an embodiment of the present invention, in the following description, the nurse call system performing the operation shown in the conventional sequence diagram of FIG. As shown in the system configuration diagram of FIG. 4, the system configuration is almost the same as the nurse call system of FIG. 1, and a plurality of private branch exchanges 200, nurse call master units 206, hospitalized patients and the like provided on each bedside. Nurse call handsets 207a, 207b,..., One to a plurality of local PHS base stations 208a, 208b, 208c,..., And a plurality of local PHS terminals 209a, 209b, 209c,. It shall be. FIG. 4 is a system configuration diagram showing a system configuration of a conventional nurse call system.

  First, the operation in the conventional nurse call system will be described with reference to the sequence diagram of FIG. After a nurse call calling operation is performed from the nurse call slave unit 207a and a call signal is transmitted to the nurse call master unit 206 as "call a" (sequence S210), another call is made at approximately the same time period. A nurse call calling operation is also performed from the nurse call slave device 207b, and a call signal is transmitted as "call b" to the nurse call parent device 206 (sequence S211).

  When the nurse call master device 206 first detects a call signal transmitted from the nurse call slave device 207a as “call a”, the nurse call master device 207a uses the call signal that is a nurse call from the nurse call slave device 207a as “call a”. It transmits to the exchange 200 (sequence S212). The call signal “call a” transmitted to the private branch exchange 200 includes the number information of each nurse's private PHS terminals 209a, 209b, 209c,... Information such as number and bed number) is set. After that, the nurse call master unit 206 sends a connection request signal indicating that any of the local PHS terminals 209a, 209b, 209c,... Of each call destination nurse has responded as “connection request a” from the private branch exchange 200. Monitor the return.

  The nurse call master unit 206 also detects the call signal transmitted from the next nurse call slave unit 207b as “call b” almost simultaneously, but the call signal for the first detected nurse call slave unit 207a. "Call a" is transmitted to the private branch exchange 200, and each nurse has already shifted to the state of calling the private PHS terminals 209a, 209b, 209c, ..., and the connection request signal "connection" for the call signal "call a" Request a "has not been received from private branch exchange 200 and is in a ringing state. Therefore, the nurse call master device 206 receives the nurse call from the next nurse call slave device 207b until the connection request signal “connection request a” corresponding to the previously transmitted call signal “call a” is returned from the private branch exchange 200. The operation of transmitting the call signal “call b” to the private branch exchange 200 is awaited.

  On the other hand, when the private branch exchange 200 detects the call signal “call a” from the nurse call master unit 206, the private PHS terminals 209a, 209b of each nurse designated as the call destination of the call signal “call a” 209c,..., Generate respective call setup signals and transmit the call setup signals to the local PHS terminals 209a, 209b, 209c,... Via the local PHS base stations 208a, 208b, 208c,. (Sequences S213, S214, S215).

  When each of the private PHS terminals 209a, 209b, 209c,... Receives the call setting signal transmitted from the private branch exchange 200, each of the private PHS terminals 209a, 209b, 209c,. (Information such as bed number) is displayed on the screen, and a ringing tone for calling is output to notify the nurse. When any of the local PHS terminals 209a, 209b, 209c,... That output the ringing tone for calling performs a response operation, for example, the local PHS terminal 209c responds to the private branch exchange 200 from the local PHS terminal 209c. A response signal is transmitted through the local PHS base station 208c (sequence S216).

  When the private branch exchange 200 receives a response signal from any of the private PHS terminals 209a, 209b, 209c,... That has transmitted the call setting signal, for example, the private PHS terminal 209c, the private branch exchange 200 transmits a call signal “call a”. The connection request signal “connection request a” indicating that the local PHS terminal 209c as the call destination has responded is transmitted to the nurse call master device 206 (sequence S217). When the nurse call master device 206 receives the connection request signal “connection request a” from the private branch exchange 200, the nurse call master device 206 sets the nurse call slave device 207a that has made the nurse call to a call state and communicates with the local PHS terminal 209c that has responded. Move to a state where you can make calls.

  Further, the private branch exchange 200 transmits a disconnection signal instructing to stop the calling operation to other private PHS terminals such as the private PHS terminals 209a and 209b other than the private PHS terminal 209c that has transmitted the response signal (sequence). S218, S219). Upon receiving a disconnection signal from the private branch exchange 200, other private PHS terminals such as the private PHS terminals 209a and 209b other than the private PHS terminal 209c delete the display content of the display and output a ringing tone for calling. Stop and move to a free state.

  The nurse call master device 206 receives the connection request signal “connection request a” from the private branch exchange 200, sets the nurse call slave device 207a to a call state, and then waits for a transmission operation to the private branch exchange 200. Check if there is a nurse call from the machine. Here, the call signal “call b”, which is a nurse call from the nurse call slave 207b, is in a waiting state. Therefore, the nurse call master device 206 takes out the call signal “call b” to be transmitted next in the waiting state, and transmits it to the private branch exchange 200 as “call b” (sequence S220). The call signal “call b” transmitted to the private branch exchange 200 includes the number information of the nurse's private PHS terminals 209a, 209b, 209c,... Information such as number and bed number) is set.

  When the private branch exchange 200 detects the call signal “call b” from the nurse call master 206, the private PHS terminals 209a, 209b, 209c of each nurse designated as the call destination of the call signal “call b”, Of these, in order to call other local PHS terminals such as the local PHS terminals 209a and 209b other than the local PHS terminal 209c set to the call state with the nurse call slave 207a, the respective call settings are made. A signal is generated, and call setting signals are transmitted to the local PHS terminals 209a and 209b via the local PHS base stations 208a and 208b (sequences S221 and S222).

  Upon receiving the call setting signal transmitted from the private branch exchange 200, each of the private PHS terminals 209a and 209b receives information (such as a room number and a bed number) regarding the caller's nurse call handset 207b set in the call setting signal. Information) is displayed on the screen and a ringing tone for calling is output to notify the nurse. When one of the local PHS terminals 209a and 209b that has output the ringing tone for calling, for example, the local PHS terminal 209b, performs a response operation, the local PHS terminal 209b sends a private PHS base to the private branch exchange 200. A response signal is transmitted via the station 208b (sequence S223).

  When the private branch exchange 200 receives a response signal from any of the local PHS terminals 209a and 209b that transmitted the call setting signal, for example, the local PHS terminal 209b, the nurse call parent that has transmitted the call signal “call b” A connection request signal “connection request b” indicating that the local PHS terminal 209b of the callee has responded is transmitted to the device 206 (sequence S224). When the nurse call master device 206 receives the connection request signal “connection request b” from the private branch exchange 200, the nurse call master device 206 sets the nurse call slave device 207 b that has made the nurse call to a call state and communicates with the responding private PHS terminal 209 b. Move to a state where you can make calls.

  Further, private branch exchange 200 transmits a disconnection signal instructing stop of the calling operation to other private PHS terminals such as private PHS terminal 209a other than private PHS terminal 209b that has transmitted the response signal (sequence S225). . When other private PHS terminals such as the private PHS terminal 209a other than the private PHS terminal 209b receive the disconnection signal from the private branch exchange 200, the display contents on the display are deleted and the output of the ringtone for calling is stopped. , Transition to a free state.

  In the operation of the conventional nurse call system shown in the sequence diagram of FIG. 3, the nurse PHS terminals 209a, 209b of nurses in the same team in the same time zone from a plurality of nurse call slave devices 207a, 207b, When nurse calls for 209c,... Occur almost at the same time (sequences S210, S211), the nurse call master unit 206 selects one of the local PHS terminals 209a, 209b, 209c,... For the nurse call of the first nurse call slave unit 207a. Until the connection request signal “connection request a” indicating the response from the private branch exchange 200 is received (sequence S217), transmission of the call signal “call b” relating to the nurse call of the subsequent nurse call slave unit 207b is waited. . Therefore, it takes time to shift the nurse call of the subsequent nurse call slave 207a to the call state, and the more nurse calls are generated in the same time zone, the more all the nurse calls are transferred to the call state. Will take longer.

  Next, the operation of the nurse call system shown in FIG. 1 as an embodiment of the present invention will be described using the sequence diagram of FIG. As in the case of sequences S210 and S211 in the sequence diagram of FIG. 3, after a nurse call calling operation is performed from the nurse call slave device 107a, a call signal is transmitted as “call a” to the nurse call parent device 106. (Sequence S110) In almost the same time zone, a nurse call calling operation is performed from another nurse call slave device 107b, and a call signal is transmitted to the nurse call parent device 106 as "call b". (Sequence S111)

  When the nurse call master device 106 first detects the call signal transmitted from the nurse call slave device 107a as “call a”, the nurse call slave device 107a receives the call signal from the nurse call slave device 107a as in the case of the sequence SS212 in the sequence diagram of FIG. A call signal that is a nurse call is transmitted to the private branch exchange 100 as "call a" (sequence S112). The call signal “call a” transmitted to the private branch exchange 100 includes the number information of each nurse's private PHS terminals 109a, 109b, 109c,... Information such as number and bed number) is set. Thereafter, the nurse call master unit 106 sends a connection request signal indicating that any of the local PHS terminals 109a, 109b, 109c,... Of each call destination nurse has responded as “connection request a” from the private branch exchange 100. Monitor the return.

  Further, when the nurse call master device 106 detects the call signal transmitted from the nurse call slave device 107b as “call b” next, unlike the conventional sequence diagram shown in FIG. Even if the call signal “call a” to the private branch exchange 100 by the nurse call from the nurse call slave unit 107a has already been transmitted, the connection request signal “connection request a” for the call signal “call a” transmitted earlier is displayed. Until returning from the private branch exchange 100, without waiting for the operation of transmitting the call signal “call b”, which is a nurse call from the nurse call slave 107b, to the private branch exchange 100, the next nurse call slave 107b immediately The call signal, which is a nurse call, is sent to the private branch exchange 100 as “call b”. To (sequence S116).

  The call signal “call b” transmitted to the private branch exchange 100 includes the number information of each nurse's private PHS terminals 109a, 109b, 109c,... Information such as number and bed number) is set. Thereafter, the nurse call master unit 106 sends a connection request signal indicating that any of the local PHS terminals 109a, 109b, 109c,... Monitor the return.

  On the other hand, when the private branch exchange 100 detects the call signal “call a” initially transmitted from the nurse call master unit 106, the call signal “call a” is output as in the case of the sequences SS213, S214, and S215 in the sequence diagram of FIG. Each nurse's premises PHS terminal 109a, 109b, 109c,... Designated as the call destination of “call a” is checked for each call, and if the call is available, In order to call the local PHS terminals 109a, 109b, 109c,..., Respective call setting signals are generated, and the local PHS terminals 109a, 109b, 109c,. ..., a call setting signal is transmitted (sequence S113, S114, S115). The call setting signal includes number information of each nurse's premises PHS terminals 109a, 109b, 109c,... Indicating information of each call destination and information on the nurse call cordless handset 107a of the caller (information such as a room number and a bed number). ) Is set.

  When each of the private PHS terminals 109a, 109b, 109c,... Receives the call setting signal transmitted from the private branch exchange 100, each of the private PHS terminals 109a, 109b, 109c,. (Information such as bed number) is displayed on the screen, and a ringing tone for calling is output to notify the nurse.

  Further, the private branch exchange 100 transmits a call setting signal relating to the call signal “call a” received first to each nurse's private PHS terminals 109a, 109b, 109c,..., And then the private PHS terminals 109a, 109b, 109c. When the call signal “call b” transmitted next from the nurse call parent device 106 is detected while the response signal “response a” is not received from any of the call signals, the call signal “call” is detected. The call status of each nurse's premises PHS terminals 109a, 109b, 109c,.

  Each nurse's premises PHS terminals 109a, 109b, 109c,... Designated as call destinations are not vacant, and are called by sending a call setting signal related to the first call signal “call a”. It is in the middle state. Therefore, the private branch exchange 100 keeps the state being called as it is, and the nurses' PHS terminals 109a, 109b, 109c,. In order to notify the mobile station, not the call setup signal but each additional information signal is generated and added to each local PHS terminal 109a, 109b, 109c,... Via the local PHS base stations 108a, 108b, 108c,. An information signal is transmitted (sequence S117, S118, S119). The additional information signal includes number information of each nurse's premises PHS terminals 109a, 109b, 109c,... Indicating information of each call destination and information on the nurse call cordless handset 107b of the caller (information such as a room number and a bed number). In addition to the above, multiple nurse call occurrence information indicating that calls by another nurse call are generated continuously is set.

  Each of the local PHS terminals 109a, 109b, 109c,... Displays information (information such as a room number and a bed number) on the caller's nurse call handset 107a set in the previously received call setting signal on the display. When the additional information signal transmitted from the private branch exchange 100 is received, the information regarding the caller's nurse call slave set 107a set in the additional information signal (room number, bed number, etc.) is displayed. Information) and multiple nurse call occurrence information indicating the continuous occurrence of a call due to another nurse call and further displayed on the display at the same time, or information on the nurse call slave unit 107a and the nurse call slave unit 107a (information such as room number and bed number) and information indicating the continuous occurrence of a call by another nurse call Alternately displayed on a screen on the vessel, to notify the nurse.

  That is, by displaying the information contained in the additional information signal on the display simultaneously or alternately, the nurses of the local PHS terminals 109a, 109b, 109c,. It is notified that a call is generated by two nurse calls 107b (more general, two or more nurse calls).

  When such operations are performed, the ring tone indicates that the nurses of the local PHS terminals 109a, 109b, 109c,... In the additional information signal, it is possible to change the ring tone for normal calling and output a special ring tone specially set for simultaneous call operation by multiple nurse calls. Information to be instructed may be set. By changing the special ring tone from the local PHS terminals 109a, 109b, 109c,..., The nurses of the local PHS terminals 109a, 109b, 109c,. It is possible to recognize more clearly that the state has occurred. Further, the special call tone may include nurse call call number information indicating how many call calls the simultaneous call operation has occurred.

  Next, when any of the local PHS terminals 109a, 109b, 109c,... That output the ringtone or special ringtone performs a response operation, for example, the local PHS terminal 109c performs a response operation. Assuming a response operation to the call setting signal “a”, a response signal “response a” is transmitted from the private PHS terminal 109c to the private branch exchange 100 via the private PHS base station 108c (sequence S120).

  The private branch exchange 100 sends a response signal “response a” from any of the private PHS terminals 109a, 109b, 109c,... That has transmitted the call setting signal related to the first call signal “call a”, for example, the private PHS terminal 109c. Is received as a response signal “response a” to the call setting signal related to the first call signal “call a” and the call destination is transmitted to the nurse call parent device 106 that has transmitted the call signal “call a”. A connection request signal “connection request a” indicating that the local PHS terminal 109c has responded is transmitted (sequence S121). When receiving the connection request signal “connection request a” from the private branch exchange 100, the nurse call master unit 106 sets the nurse call slave unit 107a that has made the nurse call to a call state and communicates with the local PHS terminal 109c that has responded. Move to a state where you can make calls.

  Further, the private branch exchange 100 transmits an additional information signal in which information indicating that the other party is the nurse call slave unit 107a is set to the private PHS terminal 109c that has transmitted the response signal “response a” (sequence). S122). Upon receipt of the additional information signal transmitted from the private branch exchange 100, the private PHS terminal 109c that has transmitted the response signal “response a” receives information indicating the call partner set in the additional information signal (the call partner is a nurse call). The information specifying that it is the slave unit 107a is displayed on the screen of the display unit, and the nurse of the local PHS terminal 109c is notified. As a result, the nurse of the local PHS terminal 109c has shifted to a call state with the patient of any nurse call slave unit among two simultaneous calls by the nurse call slave unit 107a and the nurse call slave unit 107b. Can be confirmed.

  Here, among the simultaneous calling operations by two nurse calls, even if the nurse call of the nurse call slave unit 107a shifts to the talking state, the nurse call of the nurse call slave unit 107b remains as a calling state. Therefore, unlike the conventional sequence diagram of FIG. 3, the private branch exchange 100 can receive a plurality of response signals (in this case, 2 in this case) even if it receives a response signal from a private PHS terminal whose call state is in the ringing state. No ringtones for ringing of other local PHS terminals whose call state is still set to ringing have been received since responses for the total number of calls during simultaneous ringing operations by nurse calls are not received. Without performing such an operation, the ringing state is maintained as it is, and the ringing tone or special ringing tone is continuously output.

  However, of the simultaneous calling operations by two nurse calls, when the nurse call of the nurse call slave unit 107a shifts to a call state, the call by the nurse call remaining as a calling state remains in the nurse call slave unit 107b. Since only the nurse call is made, for other local PHS terminals such as the local PHS terminals 109a and 109b in which the call state other than the local PHS terminal 109c that has shifted to the busy state is still set to the ringing state, 1 Normal call state with only one nurse call.

  Accordingly, the contents displayed on the screen of other local PHS terminals such as the local PHS terminals 109a and 109b and the ringtone to be output are sent to the local PHS terminal 109c as an additional information signal for returning the normal screen display contents and ringtone. However, in this embodiment, in order to reduce the number of signals to be transmitted and received and to suppress an increase in the processing amount, it is possible to transmit to other local PHS terminals 109a and 109b. Leave the state where there is a simultaneous ringing operation with one nurse call.

  Next, of the local PHS terminals 109a, 109b, 109c,... That output the ringtone or special ringtone, any local PHS terminal excluding the local PHS terminal 109c that has already transmitted a response signal, for example, the local PHS terminal 109b. When the answering operation is performed, the answering operation for the call setting signal of the next remaining call signal “calling b” is regarded as a reply operation for the private branch exchange 100 from the private PHS terminal 109b to the private branch exchange 100. A response signal “response b” is transmitted via 108b (sequence S123).

  When the private branch exchange 100 receives the response signal “response b” from any of the private PHS terminals 109a and 109b that transmitted the call setting signal, for example, the private PHS terminal 109b, the private branch exchange 100 relates to the last call signal “call b”. A connection request indicating that the local PHS terminal 109b as the call destination has responded to the nurse call parent device 106 that has transmitted the call signal “call b” as a response signal “response b” to the call setting signal. Signal “connection request b” is transmitted (sequence S124). Upon receipt of the connection request signal “connection request b” from the private branch exchange 100, the nurse call master unit 106 sets the nurse call slave unit 107b that has made the nurse call to a call state and communicates with the local PHS terminal 109b that has responded. Move to a state where you can make calls.

  Further, the private branch exchange 100 transmits an additional information signal in which information indicating that the communication partner is the nurse call slave unit 107b is set to the private PHS terminal 109b that has transmitted the response signal “response b” (sequence). S125). Upon receipt of the additional information signal transmitted from the private branch exchange 100, the private PHS terminal 109b that has transmitted the response signal “response b” receives information indicating the call partner set in the additional information signal (the call partner is a nurse call). The information identifying the slave unit 107b is displayed on the screen of the display unit, and the nurse of the local PHS terminal 109b is notified. As a result, the nurse of the local PHS terminal 109b transitions to a call state with the patient of any nurse call slave unit among the two simultaneous calls of the nurse call slave unit 107a and the nurse call slave unit 107b. Can be confirmed.

  Further, the private branch exchange 100 receives response signals for all calls related to simultaneous call operations by two nurse calls (more general, multiple nurse calls) from the nurse's private PHS terminal, and receives all nurse calls. When it is confirmed that the call state has been changed, the call state other than the local PHS terminal 109b that has transmitted the response signal “response b” to the call setting signal of the last call signal “call b” is set to the state still being called. A disconnect signal instructing to stop the calling operation is transmitted to the other local PHS terminals such as the local PHS terminal 109a (sequence S126). Upon receiving a disconnect signal from the private branch exchange 100, other private PHS terminals such as the private PHS terminal 109a other than the private PHS terminal 109b delete the display content of the display and stop outputting the ringtone for calling. , Transition to a free state.

  In the operation of the nurse call system of FIG. 1 shown in the sequence diagram of FIG. 2 above, the nurse PBX terminals 109a and 109b of the nurses in the same team from the plurality of nurse call slaves 107a and 107b in the same time zone. 109c,..., 109c,..., Almost simultaneously (sequences S110, S111), the nurse call master unit 106 differs from the conventional case of FIG. The first nurse call handset 107a nurse call without waiting for reception of the connection request signal “connection request a” from the private PHS terminal 109a, 109b, 109c,... Subsequent to the transmission operation (sequence S112) of the call signal “call a” regarding , Call signal relates nurse call subsequent nurse call handset 107b "Call b" be sent continuously in private branch exchange 100 (sequence S116), it is possible to shift to the simultaneous call state by a plurality of nurse call. Therefore, as compared with the conventional case of FIG. 3, the time required for the nurse call such as the subsequent nurse call slave unit 107b to shift to the call state can be greatly shortened, and many nurse calls can be made in the same time zone. Even if this occurs, the time required to shift all nurse calls to the call state can be reliably shortened.

(Description of the effect of this embodiment)
As described in detail above, the following effects are obtained in the present embodiment.

  First, even when a plurality of nurse calls from a plurality of nurse call slaves 107a, 107b,... Occur almost simultaneously, the nurse's premises PHS terminals 109a, 109b, 109c, By performing a simultaneous call operation by a plurality of nurse calls by only one call operation without waiting for a response to a call to ..., each nurse's premises PHS terminals 109a, 109b, 109c,. Since it is possible to shift to a simultaneous calling state by a plurality of nurse calls that can be continuously called, it becomes possible to make a call in response to each nurse call in a short time.

  In other words, when a plurality of nurse calls from a plurality of nurse call slaves 107a, 107b,... Occur in the same time zone, in the case of the conventional nurse call system as shown in FIG. However, it is necessary to call each nurse's local PHS terminals 109a, 109b, 109c,. Therefore, the call operation by the next nurse call is awaited until a response is received from any of the local PHS terminals 109a, 109b, 109c,..., For example, the local PHS terminal 109c. Here, when a response is obtained from one of the local PHS terminals, for example, the local PHS terminal 109c, the call operation of each remaining local PHS terminal, for example, the local PHS terminals 109a and 109b, which is still in the calling state. It is necessary to move the remaining local PHS terminals, for example, the local PHS terminals 109a and 109b to an empty state. Thereafter, the call operation by the next nurse call is performed again for each of the remaining local PHS terminals that have become free, for example, the local PHS terminals 109a and 109b.

  On the other hand, in this embodiment, simultaneous call operation by a plurality of nurse calls is performed. That is, the call operation to the local PHS terminals 109a, 109b, 109c,... For a plurality of nurse calls is only one time for the first nurse call, and it is also necessary to wait for the operation for notifying the occurrence of the subsequent nurse call. Absent. In addition, even if a response to a call by one nurse call is obtained, it is not necessary to stop the call operation of each remaining local PHS terminal that is in the call state, so a response to the call by each nurse call is obtained. It is possible to greatly reduce the time until the product is received.

  Second, when a plurality of nurse calls are generated almost simultaneously from a plurality of nurse call slaves 107a, 107b,..., The nurse's premises PHS terminals 109a, 109b, 109c,. Until the response is obtained and the call state is entered, the call to the local PHS terminals 109a, 109b, 109c,... Continues using the local PHS base stations 108a, 108b, 108c,. Since the operation is not stopped, the local PHS base used for the nurse call by interrupting another call unrelated to the call by the nurse call while performing the simultaneous call operation by a plurality of nurse calls. The communication channels of the stations 108a, 108b, 108c,. There is no traffic channel for the call, it is possible to completely prevent such a situation that it can not make a call operation by the nurse call requiring urgency.

  That is, in the case of the conventional nurse call system as shown in FIG. 3, as described above, each nurse's premises PHS terminals 109a, 109b, 109c,. It is necessary to call each time, and when a response is obtained from any of the local PHS terminals such as the local PHS terminal 109c, the remaining local PHS terminals such as the local PHS terminals 109a and 109b that are still being called After performing the operation stop operation, the call operation by the next nurse call is performed again for each of the remaining local PHS terminals, for example, the local PHS terminals 109a and 109b. Therefore, between one call and the next call, a PHS terminal not related to the nurse call shifts to a call state with another PHS terminal via the local PHS base stations 108a, 108b, 108c,. May occur. As a result, there is no space in the communication channels of the local PHS base stations 108a, 108b, 108c,... That can be used by the local PHS terminals 109a, 109b for nurse calls, and the subsequent nurse call is called by the nurse call. There are situations where it becomes impossible.

  On the other hand, in this embodiment, it is not necessary to stop the calling operation between one call (notice of occurrence of a nurse call) and the next call (notice of occurrence of a nurse call), and the state being called is continued. Therefore, it is possible to keep the call channels of the local PHS base stations 108a, 108b, 108c,... For simultaneous call operations by a plurality of nurse calls, and targets for simultaneous call operations by a plurality of nurse calls. Each of the nurse calls can obtain a response from the local PHS terminals 109a, 109b, 109c,... More reliably and quickly.

  The configuration of the preferred embodiment of the present invention has been described above. However, it should be noted that such embodiments are merely examples of the present invention and do not limit the present invention in any way. Those skilled in the art will readily understand that various modifications and changes can be made according to a specific application without departing from the gist of the present invention.
