Description

  The present invention relates to a nurse call system, and is particularly suitable for use in a nurse call system having a sequential call function for sequentially calling a plurality of portable terminals in response to a single call from a nurse call slave. .

  In general, in hospitals and care facilities, nurse calls are used to contact patients and care recipients (hereinafter simply referred to as “patients”) with doctors, nurses, and caregivers (hereinafter simply referred to as “nurses”). The system is used. In recent years, nurse call systems have been equipped with portable terminals for nurses to carry and can be called from nurse call terminals of patients to nurse portable terminals. .

  In a nurse call system employing a portable terminal, a system is also provided in which a plurality of portable terminals are ringed by a call from one patient, and a nurse who first responds with the portable terminal can talk to the patient. Here, there is one that rings a plurality of portable terminals in order from the highest registered priority (for example, see Patent Document 1). Such a sequential calling mechanism is effective, for example, when team nursing is performed to support one patient with a plurality of nurses.

  In the nurse call system described in Patent Literature 1, when a call is made from a nurse call slave used by a patient, the first mobile terminal is called based on the slide call information, and the mobile terminal responds for 30 seconds. If there is no call, the second call is made to the next portable terminal based on the slide call information.

JP 2005-349020 A

  However, when sequential calling is performed by team nursing, the nurse using the mobile terminal with the earliest calling order cannot respond during the nursing work, and the mobile terminal with the later calling order When a response is made, there is a problem that it takes a long time for the nurse to respond to a call from the nurse call cordless handset.

  The present invention has been made to solve such problems, and in the case of sequentially calling a plurality of portable terminals, the nurse responds to the call from the nurse call slave by the portable terminal. The purpose is to be able to shorten the time to the shortest possible.

  In order to solve the above-described problem, in the present invention, the time until a response is made on a mobile terminal in response to a call from a nurse call slave unit based on call history information recorded on the call and response of a nurse call. Detects a slow response time zone in which becomes longer than a predetermined value. Then, when there is a call from the nurse call slave in the slow response time zone, the call to the n-th (n ≧ 2) or later mobile terminals and the call to the plurality of mobile terminals are spaced at intervals of the first predetermined time. Control is made so that the time until the call is shortened compared with the case of performing in order with a gap between the two.

  According to the present invention configured as described above, a call from the nurse call slave unit is detected in the delayed response time period in which the time from the occurrence of the call by the nurse call slave unit to the response is detected as being longer than a predetermined value. If there is, when the call is sequentially made to a plurality of portable terminals, the time until the nth (n ≧ 2) or later portable terminals are called is controlled to be shorter than usual. As a result, even when a response is made by a mobile terminal that is called later (nth or later mobile terminal), the time from the occurrence of a call by the nurse call slave to the response is shorter than before. can do.

The wireless base station 8 is used for wireless communication of calls and data with the mobile terminal 10 and is connected to the PBX 7.

  FIG. 2 is a block diagram illustrating a functional configuration example of the nurse call parent device 1. As shown in FIG. 2, the nurse call base unit 1 includes, as its functional configuration, a management information storage unit 11, a call history storage unit 12, a late response time zone storage unit 13, a first interface unit 21, and a second interface. Unit 22, call reception unit 23, response reception unit 24, information recording unit 25, late response time zone detection unit 26, and call control unit 27.

  Each of the functional blocks 21 to 27 can be realized by any of a hardware configuration, a DSP (Digital Signal Processor), and software. For example, when realized by software, each of the functional blocks 21 to 27 is actually configured by including a CPU, RAM, ROM, and the like of a computer, and is stored in a recording medium such as a RAM, a ROM, a hard disk, or a semiconductor memory. Is realized by operating.

  The management information storage unit 11 includes information related to a patient (hereinafter referred to as patient information), information related to a nurse (hereinafter referred to as nurse information), and information related to a call destination of a nurse call (hereinafter referred to as call destination information). It is stored as management information regarding nurse calls.

  In this embodiment, the patient information includes, for example, the patient's name, the room number of the hospital room, the bed number for identifying the bed used by the patient, the patient ID for identifying the patient, and the nurse call cords 4 and 5 to be used. Various information such as a handset ID for identifying the device is included. The nurse information includes, for example, a nurse's name, a nurse ID for identifying the nurse, a patient ID for identifying the patient in charge, and a terminal ID for identifying the mobile terminal 10 to be used. Contains various information.

  The call destination information includes a patient (for example, a patient ID), a nurse in charge (for example, a nurse ID) that makes a call in response to a nurse call from the patient, and the mobile terminal 10 possessed by the nurse in charge. The terminal ID and the information about the call destination (extension number and the like) are stored in association with each other. When team nursing is performed to support a single patient with a plurality of nurses, a single patient, a plurality of nurses, and call destinations of a plurality of portable terminals 10 possessed by each nurse are grouped and stored. In addition, information that defines a priority order when sequentially calling a plurality of portable terminals 10 is also stored.

  The first interface unit 21 communicates with the controller 2. The second interface unit 22 communicates with the handin squall main device 6.

  The call reception unit 23 receives a call from the nurse call slave units 4 and 5 and performs a predetermined notification process. That is, the call reception unit 23 receives a call signal transmitted from the nurse call slave units 4 and 5 via the hallway lamp 3 and the control unit 2 via the first interface unit 21. Then, the call is made by referring to the management information storage unit 11 based on the handset information (the handset ID for specifying the nurse call handset 4 or 5 that made the call) conveyed by the received call signal. Identify the patient who performed.

  Then, the call reception unit 23 reads a part of patient information (for example, name, room number, bed number, etc.) related to the identified patient from the management information storage unit 11, generates a pop-up screen of patient information, and displays a display (not shown) To display. Moreover, the call reception part 23 alert | reports to a nurse by sounding a ringing tone from the speaker which the nurse call main | base station 1 does not illustrate.

  In addition, the call reception unit 23 is patient information of the patient identified as described above (for example, information such as a child device ID that identifies the nurse call child devices 4 and 5 that performed the call or a patient name that identifies the patient). Is supplied to the information recording unit 25 and stored in the call history storage unit 12. Further, the call reception unit 23 supplies the call signal received from the nurse call slave units 4 and 5 to the call control unit 27 together with the patient information specified as described above, and instructs the mobile terminal 10 to be called.

  Upon receiving an instruction from the call reception unit 23, the call control unit 27 reads out call destination information of the nurse in charge corresponding to the patient specified by the call reception unit 23 from the management information storage unit 11, and the read call destination information Based on the above, a call is made to a plurality of mobile terminals 10 grouped for team nursing. Specifically, the call control unit 27 transmits a call signal instructing execution of a call to the mobile terminal 10 from the second interface unit 22 to the PBX 7 via the hand-in-hand call main device 6, thereby Make a call to 10. Here, the call control unit 27 performs control so that calls to the grouped mobile terminals 10 are sequentially executed with a certain delay time.

  The PBX 7 performs a call to a plurality of portable terminals 10 designated as call destinations in response to a call signal received from the nurse call master device 1 via the hand-in-hand call main device 6. When a response is made at any of the mobile terminals 10 in response to a call from the PBX 7, a response signal for a call start request is sent from the mobile terminal 10 that has made the response. When the PBX 7 receives the response signal, the PBX 7 transmits the response signal to the nurse call parent device 1 via the hand-in-hand call main device 6. Thereafter, a call start approval approval signal is sent from the nurse call master unit 1 to the portable terminal 10 via the hand-held call main device 6 and the PBX 7 to start the call.

  The response receiving unit 24 receives a response from the nurse call parent device 1 or the portable terminal 10 and performs a predetermined response process. For example, when the nurse off-hooks the handset of the nurse call parent device 1 in order to respond to the call from the patient, the response reception unit 24 receives the off-hook, and the above-described notification processing and call control by the call reception unit 23 The calling operation by the unit 27 is stopped.

  Further, when the nurse off-hooks the portable terminal 10 in order to answer the call from the patient, a response signal is transmitted to the nurse call master unit 1 via the handin call main device 6 and via the second interface unit 22. To the response reception unit 24. In response to this response signal, the response reception unit 24 stops the notification process by the call reception unit 23 and the call operation by the call control unit 27.

  Further, when receiving a response signal sent from the mobile terminal 10, the response receiving unit 24 receives terminal information (information such as a terminal ID or an extension number for specifying the mobile terminal 10) conveyed by the received response signal. ) To identify the nurse who made the response by referring to the management information storage unit 11. Then, the response reception unit 24 supplies the nurse information of the identified nurse (for example, information such as the terminal ID or the nurse's name) to the information recording unit 25 and stores it in the call history storage unit 12.

  As described above, when the nurse call master unit 1 or the mobile terminal 10 responds to the call from the nurse call slave units 4 and 5, the information recording unit 25 calls the call history information regarding the call and the response. Is stored in the call history storage unit 12. That is, the information recording unit 25 makes a call when a call is made from the nurse call slave units 4 and 5 by the patient, that is, when the call receiving unit 23 receives a call from the nurse call slave units 4 and 5. The patient information of the performed patient is stored in the call history storage unit 12 together with the call date and time (the date and time when the call reception unit 23 received the call signal).

  In addition, the information recording unit 25 is used when the nurse responds to the call from the nurse call slave units 4 and 5 by the patient using the nurse call master unit 1 or the portable terminal 10, that is, the response reception unit 24 sets the nurse call parent unit. When a response from the device 1 or the portable terminal 10 is received, the nurse information of the nurse who made the response is stored in the call history storage unit 12 together with the response date and time (the date and time when the response reception unit 24 received the response signal). At this time, the information recording unit 25 causes the call history storage unit 12 to store information related to the response in association with the previously stored information related to the call.

  FIG. 3 is a diagram illustrating an example of call history information stored in the call history storage unit 12. In the example shown in FIG. 3, for each record, history information 31 relating to a call and history information 32 relating to a response made in response to the call are stored for each individual call. The call history information 31 includes a handset ID that identifies the nurse call supply 4, 5 used by the calling patient and the call date and time. In addition, the history information 32 regarding the response includes a terminal ID that identifies the mobile terminal 10 used by the nurse who made the response, and the response date and time. In addition, when a response is made by the nurse call master unit 1, only the response date and time are stored, and the terminal ID is not stored.

  Based on the call history information stored in the call history storage unit 12, the slow response time zone detection unit 26 determines the time until the mobile terminal 10 responds to a call from the nurse call slave units 4 and 5. A time zone that is longer than a predetermined value is detected. Here, the time from the occurrence of the call to the response (hereinafter referred to as “call-response time”) can be obtained by subtracting the call date from the response date stored in the call history storage unit 12. The unit of the time zone can be set in advance to an arbitrary value such as 1 hour unit, 2 hour unit, or 3 hour unit.

  For example, when the unit of the time zone is set to 3 hours, the slow response time zone detection unit 26 targets the call history information for a certain period (for example, the latest one week) as 0 to 3 o'clock, 3 o'clock. The average value of the call-response time is calculated for each time zone from 6:00 to 6:00,. Then, by determining for each time zone whether or not the calculated average value of the call-response time is longer than the predetermined value, the time zone in which the call-response time is longer than the predetermined value ( "Slow response time zone"). The slow response time zone storage unit 13 stores the slow response time zone detected by the slow response time zone detection unit 26 for a certain period (for example, one week) until the next time or the late response time zone is detected.

  The call control unit 27 described above, when there is a call from the nurse call slave units 4 and 5 outside the late response time zone detected by the late response time zone detection unit 26, the time interval between sequential calls to the plurality of mobile terminals 10 A first predetermined time (for example, 30 seconds) is set as a fixed delay time for determining the number of mobile terminals 10 in order at intervals of the first predetermined time.

  On the other hand, when there is a call from the nurse call slave units 4 and 5 in the late response time zone detected by the late response time zone detection unit 26, the call control unit 27 has a fixed delay time than the first predetermined time. A short second predetermined time (for example, 20 seconds) is set, and the plurality of mobile terminals 10 are sequentially called at intervals of the second predetermined time.

  4 and 5 are flowcharts showing an operation example of the nurse call system configured as described above according to the present embodiment. Among these, FIG. 4 is a flowchart showing an example of the operation of the slow response time zone detection unit 26, which is always executed while the power source of the nurse call master unit 1 is on.

  The slow response time zone detector 26 determines whether or not it is time to detect the late response time zone (step S1). Here, it is determined whether or not a certain period (for example, one week) set as an interval period for detecting the late response time period has elapsed since the previous detection. Here, if it is not the detection timing of the late response time zone, the determination in step S1 is repeated.

  On the other hand, when the detection timing of the late response time zone comes, the late response time zone detection unit 26 calls the response time of the call based on the call history information for the most recent week stored in the call history storage unit 12. A late response time zone that is longer than the predetermined value is detected (step S2). Then, the late response time zone detected this time is newly stored in place of the late response time zone detected last time and stored in the late response time zone storage unit 13 (step S3). Thereafter, the process returns to step S1.

  FIG. 5 is a flowchart showing an example of sequential call operation for a plurality of portable terminals 10 by the nurse call parent device 1. The flowchart shown in FIG. 5 starts when a call is made by the nurse call slave units 4 and 5.

  First, the call reception unit 23 determines whether or not a call from the nurse call slave units 4 and 5 has been received (step S11). Here, when the call reception unit 23 has not received a call from the nurse call slave units 4 and 5, the determination in step S11 is repeated.

  On the other hand, when the call acceptance unit 23 accepts a call from the nurse call slave units 4 and 5, the call acceptance unit 23 refers to the management information storage unit 11 based on the slave unit information conveyed by the received call signal. Thus, the calling patient is specified, and a predetermined notification process is executed by the nurse call parent device 1 (step S12). Further, the information recording unit 25 stores the caller ID and call date and time of the nurse call slaves 4 and 5 used for calling in the call history storage unit 12 (step S13).

  Next, the call control unit 27 refers to the late response time zone storage unit 13 and determines whether or not the time when the call is made corresponds to the late response time zone (step S14). Here, when the time of the call does not correspond to the late response time zone, the call control unit 27 sets a first predetermined time (for example, 30 seconds) as a fixed delay time that sequentially determines the call time interval. (Step S15). On the other hand, when the time when the call is made corresponds to the late response time zone, the call control unit 27 sets a second predetermined time (for example, 20 seconds) as a certain delay time (step S16).

  Then, the call control unit 27 refers to the management information storage unit 11 and calls the i-th (i = 1, 2,..., I = 1 in the initial state) mobile terminal 10 from the highest priority. Execute (Step S17). Thereafter, the response receiving unit 24 determines whether a response from the nurse call parent device 1 or the mobile terminal 10 has been received (step S18).

  If the response accepting unit 24 has not accepted the response, the call control unit 27 starts a call for a certain delay time (the first predetermined time set in step S15 or the second set in step S16). It is determined whether any of the predetermined time has elapsed (step S19). If the certain delay time has not yet elapsed, the process returns to step S18 to continue calling the mobile terminal 10.

  On the other hand, when a certain delay time has elapsed without a response, the call control unit 27 transitions to calling the mobile terminal 10 with the next highest priority, so i = i + 1 (step S20), and the process proceeds to step S17. Return to. And the call with respect to the following portable terminal 10 is performed.

  When the call control unit 27 is executing such sequential calls, when the response receiving unit 24 receives a response from the nurse call parent device 1 or the portable terminal 10 (step S18: Yes), the call receiving unit 23 receives the nurse. The notification process of the call base unit 1 is stopped, and the call control unit 27 stops the call process of the mobile terminal 10 (step S21).

  Then, the information recording unit 25 stores the terminal ID of the mobile terminal 10 used for the response and the response date and time (only the response date and time when responding at the nurse call master unit 1) in the call history storage unit 12 (step S22). ). Thereby, the process shown in the flowchart of FIG. 5 regarding one nurse call is completed.

  As described above in detail, in the present embodiment, the delayed response time period in which the call-response time is longer than the predetermined value based on the call history information stored in the call history storage unit 12 for the call and response of the nurse call. Is detected. When there is a call from the nurse call slaves 4 and 5 in the delayed response time zone, a predetermined delay time that determines the time interval of the sequential call is set to be shorter than the normal first predetermined time (30 seconds). 2 is set to a predetermined time (20 seconds).

  According to this embodiment configured as described above, in the late response time zone in which the call history information indicates that the call-response time is longer than the predetermined value, the second and subsequent mobile terminals 10 are called. Since the time interval is set short, the call-response time can be shortened compared to the conventional case even when a response is made in the portable terminal 10 with a low priority and a low order of calling.

  In the above-described embodiment, the example in which the second predetermined time is set to a predetermined fixed time has been described, but the present invention is not limited to this. For example, the value of the second predetermined time may be determined based on the average value of the call-response time calculated when the late response time zone detection unit 26 detects the late response time zone.

  That is, in the above embodiment, when the average value of the call-response time calculated for each time zone exceeds one predetermined value, it is only determined that the corresponding time zone is a late response time zone. It was. On the other hand, for example, when the first predetermined value to the mth predetermined value (m ≧ 2) are set and the call-response time exceeds the smallest first predetermined value, the delay response time zone It is possible to determine that there is, and to change the value of the second predetermined time depending on which predetermined value is exceeded. Here, it is preferable to shorten the second predetermined time as it exceeds a larger predetermined value.

  Further, in the above embodiment, when there is a call from the nurse call slaves 4 and 5 in the late response time zone, the call to the mobile terminal 10 after the nth (n ≧ 2) is performed for each first predetermined time. As an example of an operation that is performed so that the time until the call is shortened as compared to the normal case where the intervals are sequentially performed at intervals, a plurality of mobile phones are spaced at intervals of a second predetermined time that is shorter than the first predetermined time. The example which performs the call with respect to the terminal 10 in order was demonstrated. However, the present invention is not limited to this example.

  For example, when there is a call from the nurse call slave units 4 and 5 in the late response time zone detected by the late response time zone detection unit 26, the call control unit 27 starts calling the first mobile terminal 10. If no response is received after the first predetermined time has elapsed, the second and subsequent portable terminals 10 may be called all at once. Alternatively, when there is no response after the second predetermined time has elapsed since the start of calling the first mobile terminal 10, the second and subsequent mobile terminals 10 may be called all at once.

  Alternatively, when there is a call from the nurse call slave units 4 and 5 in the late response time zone detected by the late response time zone detection unit 26, the call control unit 27 performs the first predetermined time or the second predetermined time. Calls to the n-1 (n ≧ 3) th mobile terminals 10 in order from the first one at intervals, and when there is no response from the n-1 th mobile terminal 10, You may make it call the portable terminal 10 all at once.

  In this case, for example, based on the value of the quotient obtained by dividing the average value of the call-response time calculated when the late response time zone detection unit 26 detects the late response time zone by the first predetermined time. , N may be determined. For example, if the average value of the call-response time in a certain slow response time zone is 96 seconds and the first predetermined time is set to 30 seconds, “96 ÷ 30 = 3, remainder 6”, so the value of n Is set to 3. That is, until the second device is called in order with an interval of 30 seconds, and after the 60 seconds, the third and subsequent portable terminals 10 are called all at once. The calculated quotient value + 1 may be set as the value of n (n = 4 in the above example).

  In the above-described embodiment, an example has been described in which an average value of call-response times in each time zone is calculated, and a time zone in which this average value exceeds a predetermined value is detected as a late response time zone. Is not limited to this. For example, a maximum value of the call-response time in each time zone may be obtained, and a time zone in which this maximum value exceeds a predetermined value may be detected as a late response time zone.

  Further, in the above embodiment, as shown in FIG. 3, the handset ID related to the call, the call date / time, and the terminal ID related to the response and the response date / time are stored as call history information, and from the difference between the response date / time and the call date / time. Although an example of calculating the call-response time has been described, the method for storing the call history information is not limited to this. For example, instead of the response date and time, the elapsed time from the call date and time (that is, the call-response time) may be stored.

  In the above-described embodiment, an example in which the nurse call parent device 1 controls sequential calls to a plurality of mobile terminals 10 has been described, but the present invention is not limited to this. For example, the PBX 7 may control sequential calls to a plurality of portable terminals 10 according to the control by the call control unit 27 of the nurse call parent device 1. Alternatively, each function of the management information storage unit 11, the call history storage unit 12, the late response time zone storage unit 13, the information recording unit 25, the late response time zone detection unit 26, and the call control unit 27 is provided to the controller 2. It may be.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.

The nurse call system according to claim 1, wherein calls to the plurality of mobile terminals are performed in order with a gap between the call and the call.   Based on the time until the mobile terminal responds to the call from the nurse call slave unit, which is obtained when the slow response time zone detection unit detects the slow response time zone, The nurse call system according to claim 2, wherein a predetermined time value is determined.   The call control unit starts calling the first mobile terminal after calling the first call terminal when there is a call from the nurse call slave unit in the late response time zone detected by the late response time zone detection unit. 2. The second and subsequent portable terminals are simultaneously called when there is no response after a predetermined time or a second predetermined time shorter than the first predetermined time. Nurse call system.   The call control unit is shorter than the first predetermined time or the first predetermined time when there is a call from the nurse call slave in the late response time zone detected by the late response time zone detection unit. When calling from the first to the (n−1) (n ≧ 3) mobile terminals in order at intervals of the second predetermined time, and when there is no response from the n−1 mobile terminals, The nurse call system according to claim 1, wherein nth and subsequent mobile terminals are called all at once.   The time required for the mobile terminal to respond to the call from the nurse call slave device, which is obtained when the slow response time zone detecting unit detects the slow response time zone, is the first predetermined time. 6. The nurse call system according to claim 5, wherein the value of n is determined based on a value of a quotient obtained by dividing by.
