Description

  The present invention relates to a nurse call system, a nurse call control method, and a nurse call control program, and particularly to a nurse who has received an incoming call to a nurse terminal by a nurse call from a patient, and a patient who has made a nurse call. The present invention relates to a nurse call system, a nurse call control method, and a nurse call control program that make it possible to recognize whether or not it is the nearest nurse to respond.

  2. Description of the Related Art Conventionally, there is a nursing support method in which a patient admitted to a medical institution including a hospital calls a plurality of nurses in charge at the same time using a nurse call cordless handset in an emergency. However, it is not always the case that the nurse who responded the earliest among the nurses who were called stayed near the patient who made the nurse call. There was a thing that it took. In addition, when a patient calls a plurality of nurses using a nurse call slave, another patient tries to call the same nurses using a nurse call slave. However, no other patient can make a call to the nurse until one of the nurses answers the first patient's call.

  In order to solve such a situation, as a method of calling the nearest mobile station, for example, a PHS (Personal Handy-phone System) terminal, for example, Japanese Patent Application Laid-Open No. 10-042340 “Mobile Station Calling Method and Mobile Station Calling Device” Etc. have been proposed. The technique described in Patent Document 1 specifies, for example, one or more base stations that cover an area of the current position where a PHS terminal that has made a nurse call is located, and is located within the area of the specified base station In this technique, only the PHS terminal of the person in charge is called, and it is possible to promptly contact the requester, for example, the person in charge near the patient, such as a nurse.

Japanese Patent Laid-Open No. 10-042340 (page 2-4)

  However, in the conventional technique, even in the method of calling only the nearest mobile station, for example, a PHS cordless handset as described in Patent Document 1, which nurse is the nearest among a plurality of called nurses. There is no mechanism to clearly indicate that he is a nurse, so even if he is the nearest nurse, there is a motivation that the nurse should respond positively to the call. There are aspects that have not been made. Also, if the call cannot be made because the nearest nurse's PHS cordless handset is out of range, or the nearest nurse may respond to other patients If it was not possible, switching to a call to another PHS slave unit would be delayed, and there was a problem that the response was delayed and it was impossible to respond in an emergency.

(Object of the present invention)
The present invention has been made in view of such circumstances, and when there is a nurse call from a hospitalized patient in a medical institution such as a hospital, a nurse located near the patient who performed the nurse call If the nurse who can respond to the call can be surely recognized and that the nearest nurse cannot answer, the next nearest nurse The purpose is to make it possible to recognize that the nurse who should respond to is. In other words, the present invention proactively responds to the nearest nurse who can respond when there is a nurse call from a hospitalized patient in a medical institution such as a hospital. 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 having a mechanism capable of recognizing whether or not to be a nurse.

  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) A nurse call system according to the present invention receives a nurse call from a patient terminal of a hospitalized patient and calls one or more nurse terminals among the nurse terminals carried by each of the nurses. In the nurse call system for performing nursing, when calling the nurse terminal of each of one or more nurses, the positional relationship between the place where the patient who made the nurse call is located and the place where the one or more nurses are currently present And changing the character information displayed on the screen for the nurse terminal and the ring tone output from the nurse terminal to call the nurse terminal for each nurse. .

  (2) The nurse call control method according to the present invention is applicable to one or a plurality of nurse terminals among the nurse terminals carried by each of a plurality of nurses by receiving a nurse call from a patient terminal of a hospitalized patient. A nurse call control method for making a call, where one or more nurses call each of the nurse terminals and the place where the patient who made the nurse call is located and where one or more nurses are currently present And changing the character information displayed on the screen of the nurse terminal and the ringtone output from the nurse terminal according to the positional relationship between the nurse terminal and calling the nurse terminal of each nurse. It is characterized by.

  (3) The nurse call control program program according to the present invention is characterized in that 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, based on the positional relationship between the patient who made the nurse call and each nurse, the nurse terminal carried by the nurse closest to the place of the patient who made the nurse call, Because it is possible to make a call by displaying a screen with special character information indicating that it is closest and outputting a special ring tone, the nearest nurse can select the patient who has made the nurse call. It is possible to reliably recognize that the nurse is near and should respond in response to the patient's call. Thus, the nurse closest to the patient who made the nurse call can respond with a positive awareness that he is the nurse he should respond to. It is possible to move quickly to the patient who performed.

  Second, based on the positional relationship between the patient who made the nurse call and each nurse, each nurse was shifted by a predetermined time difference in the order of the nurse who was near the place of the patient who made the nurse call. It is also possible to sequentially call the nurse terminals carried by the. Thus, when multiple patients at remote locations try to call a nurse at the same time, each patient is different from the case where all nurses call the nurse terminal at the same time. The nurses near can be called separately, so that different nurses can quickly move to each patient.

(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, each nurse is presently prepared for a case where a patient admitted to a medical institution such as a hospital tries to call a nurse using a patient terminal (nurse call cordless handset) in an emergency. A patient who makes a nurse call when calling a nurse's terminal carried by each nurse who regularly collects the location (position) every time the location moves or at a predetermined cycle The main feature is that the character information displayed on the screen of each nurse terminal and the ringtone output from the nurse terminal are changed according to the positional relationship between the nurse and the nurse.

  More specifically, the present invention relates to the case where a patient who is hospitalized in a medical institution such as a hospital calls a nurse using a patient terminal (nurse call slave unit), and most of the patients who have made a nurse call. Notify the nurse terminal carried by the nearest nurse present nearby that the nurse is the nearest nurse and actively answer the call to the nurse. So that they can recognize that they should respond by calling them using a special character information display and a special ringtone output that have been set in advance. The main feature is to notify that there is a nearest neighbor.

  In addition, the nurse's terminal of the nurse that is closest to the patient who made the nurse call is in a busy state, or cannot respond to other patients (such as call rejection or Even if the power is off, the nurse who is next to the patient who made the nurse call is regarded as the nurse who should respond in response to the call. It is also a main feature that notification is made using special character information display and special ringtone output.

  Thus, a nurse who has received a notification using special character information display and special ringtone output is a nurse who is closest to the patient who made the nurse call and should respond to the patient. Can respond to the patient's call positively, can contact the patient who made the nurse call promptly, and promptly return to the patient who made the nurse call Can move.

  In addition, the location (position) where each nurse is located is periodically collected every time the location is moved or at a predetermined cycle, so that multiple patients at remote locations can receive each patient terminal almost simultaneously. (Nurse call cordless handset) When trying to call a nurse at a predetermined time difference, the nurses are sequentially placed in the order of closeness to each patient who made the nurse call. Another feature is that it is possible to make a time difference call.

  By making a time difference call like this, in the case of making simultaneous call to each nurse's terminal for each simultaneous nurse call from multiple patients, each nurse's Calls from other patients until all nurse terminals have transitioned to the call state from the first patient and one of the nurse terminals responds to the call from the first patient The situation of being unable to do so can be avoided, and nurses near each patient can be called separately.

  In addition, when making a time difference call, each nurse is called by what number he / she is called by the screen display of special character information indicating the call order to each nurse's terminal and the output of a special ring tone. Can be recognized. Thus, the first called nurse can recognize that he is the closest nurse to the patient who made the nurse call and is the nurse who should respond to the patient. By actively responding to the call, it is possible to promptly contact the patient who made the nurse call, and to move quickly to the patient who made the nurse call.

  Here, each private base station 120 is assigned a unique number that can identify each base station number (CS number), and each base station number (CS number) is stored in the nurse call control device 110. Pre-registered and saved.

  Also, each nurse terminal 130 is given a unique terminal number for identifying each nurse terminal number, and each time the location is moved, the location (position) where each nurse is located or A base station number (CS number) that identifies a local base station 120 capable of wireless communication at a location where the nurse is currently located, as periodically illustrated in FIG. In association with each other, the nurse terminal number of the nurse terminal 130 of each nurse is stored in the accommodated nurse terminal number storage unit 150 in the nurse call control device 110. FIG. 7 is a table showing an example of the terminal number storage unit 150 for accommodating nurses in the nurse call control device 110 shown in FIG. 1, which is composed of a two-stage table, and the parent table has the CS number 150a and the accommodating nursing. An example in which the child table composed of the nurse's terminal link information 150b and indexed by each of the accommodating nurse's terminal link information 150b is composed of the accommodating nurse's terminal number 150c0 to the accommodating nurse's terminal number 150c7 is shown. Yes.

  In the setting example of the terminal number storage unit 150 for accommodating nurses shown in FIG. 7, for example, the accommodating nursing whose CS number 150a is “CS-0”, that is, the base station number (CS number) of the local base station 120 is “0”. The terminal number 150c0 for the accommodating nurse linked to the “accommodating link-0” of the terminal link information 150b for the nurse is set to “terminal number for nurse−0” and “terminal number for nurse−1”. In the wireless communication area of the local base station 120 with the base station number (CS number) “0”, the nurse terminal 130 with the nurse terminal number “0” and the nurse terminal number In this example, there are two nurse terminals 130, i.e., a nurse terminal 130 with “1”.

  In addition, the accommodation number to which “accommodation link-7” of the terminal link information 150b for accommodation nurse whose CS number 150a is “CS-7”, that is, the base station number (CS number) of the local base station 120 is “7” is linked. In the nurse terminal number 150c7, only “nurse terminal number −15” is set, and the wireless communication area of the local base station 120 whose base station number (CS number) is “7” is currently In this example, only the nurse terminal 130 having the nurse terminal number “15” exists.

  The fixed patient terminal 100 is given a room number of each of the hospital rooms and the like, and as illustrated in FIG. 6, for each room number of the patient room, the fixed patient terminal is fixed. The base station number (CS number) for identifying the nearest local base station 120 physically located closest to each room (such as a hospital room) in which 100 is placed is stored in the nurse call control device 110. It is registered in the nearest CS number list 140. FIG. 6 is a table showing an example of the nearest CS number list 140 in the nurse call control device 110 shown in FIG. 1, and shows an example composed of a room number 140a and a nearest CS number 140b.

The location information of the terminal 100 is “near the second-floor toilet” as shown in the structural example of the hospital in FIG. 2 and is located in the wireless communication area of the local base station 120 whose CS number 190a is “1”. The location information of the moving patient terminal 100 indicates “corridor near the hospital room 202” as shown in the structural example of the hospital in FIG. 2.

(Description of operation of embodiment)
Next, an example of the operation of the nurse call system shown in FIG. 1 will be described with reference to FIGS. 3 to 14. As the local base station 120, the nurse terminal 130, and the moving patient terminal 200, a wireless LAN (Local Area Network) parent device (access point) and a wireless LAN child device may be used. In the following description, a case where a PHS (Personal Handy-phone System) base station and a PHS terminal are used will be described.

  Each nurse working in a medical institution such as a hospital carries a nurse terminal 130 as a wireless terminal for receiving a nurse call. The nurse terminal 130 carried by the nurse is based on one or more premise base stations 120 (in the example of the hospital shown in FIG. 2) installed in a medical institution such as a hospital according to the current position of the nurse. , Any one of the eight on-site base stations 120) is located in one or a plurality of wireless communication areas and is accommodated in the on-site base station 120 in the existing wireless communication area. Wireless communication is possible.

  When the nurse moves in the hospital according to the work, the on-site base station 120 in which the nurse terminal 130 carried is changed as shown in FIG. FIG. 3 is a schematic diagram for explaining how the on-site base station 120 of the accommodation destination of the nurse's terminal 130 carried changes with the movement of the nurse. In the schematic diagram of FIG. 3, the nurse moves from the wireless communication area of the local base station 120 having the base station number (CS number) “0” to the wireless communication area of the local base station 120 having the base station number (CS number) “1”. The local base station 120 that is the accommodation destination of the nurse terminal 130 carried by the nurse is changed from the local base station 120 having the base station number (CS number) “0” to the base station. The local base station 120 with the number (CS number) “1” is changed.

  When there is a change in the on-site base station 120 accommodated in such a manner, the on-site base station of the base station number (CS number) '1' that has detected the nurse terminal 130 that has newly moved to the wireless communication area 120 notifies the nurse call control device 110 of location registration information related to the nurse terminal 130 carried by the nurse. The nurse call control device 110 that has received the location registration information updates the contents stored in the terminal number storage unit 150 for the accommodating nurse shown in FIG. In addition, the nurse call control device 110 periodically collects the current position of each nurse terminal 130 from each local base station 120 at a predetermined period, and stores the terminal number storage unit for the accommodated nurse shown in FIG. An operation of updating 150 stored contents is also performed.

(Example of call operation from patient terminal to nurse terminal)
Next, an example of the operation of preferentially calling the nearest nurse from the fixed patient terminal 100 or the moving patient terminal 200 will be described using the flowchart shown in FIG. FIG. 11 is a flowchart for explaining an example of an operation of preferentially calling the nearest nurse from the patient terminal 100 for fixation or the patient terminal 200 for movement, and the patient uses the patient terminal 100 for fixation. Alternatively, by pressing the call button of the patient terminal 200 for movement, a nurse carried by the nearest nurse who is located in the patient's room or the place closest to the place where the patient is moving. The terminal 130 is notified of the fact by displaying special character information and outputting a special ring tone that are predetermined to explicitly indicate that the nurse is the nearest nurse. Shows when to do.

  When a patient presses a call button on a fixed patient terminal 100 or a moving patient terminal 200 fixedly installed in a hospital room, the patient terminal for fixing a patient room in which the patient is present When the nurse call control device 110 is notified of a call from the patient terminal for movement 100 carried by the patient 100 or the patient being moved to the nurse terminal 130, the flowchart of FIG. 11 is activated. The When the flowchart of FIG. 11 is activated, the nurse call control device 110 determines whether the type of the patient terminal that performed the nurse call is the fixed patient terminal 100 or the moving patient terminal 200. Is confirmed (step A10). Here, the notification includes information indicating a transmission source. When the type of patient terminal is the patient terminal 100 for fixation, the notification further includes the room number of the hospital room.

  When the type of the patient terminal that performed the nurse call is the fixed patient terminal 100 (in the case of “fixed terminal” in Step A10), the room number included in the transmission source information is used. Referring to the nearest CS number list 140 shown in FIG. 6, the base station number (CS number) physically closest to the room with the room number is extracted as the nearest CS number (step A20). Further, using the room number included in the transmission source information, the patient terminal (for fixing) location information list 180 shown in FIG. After extracting as the location information where the fixed patient terminal 100 is located (step A21), the process proceeds to step A30.

  In addition, when the type of the patient terminal that has made the nurse call is the mobile patient terminal 200 (in the case of “mobile terminal” in step A10), the sender information includes the nurse's nurse. Since the base station number (CS) number of the local base station 120 that has notified the nurse call control device 110 that the terminal 130 is being called is included, the base station number (CS) number is The local base station number (CS number) indicating the local base station 120 physically closest to the moving patient terminal 200 is extracted (step A22). Further, using the base station number (CS number) included in the transmission source information, the base station number (CS number) is referred to the patient terminal (for movement) location information list 190 shown in FIG. After the location where the local base station 120 is located is extracted as location information where the mobile patient terminal 200 that performed the nurse call is located (step A23), the process proceeds to step A30.

  In step A30, details will be described later with reference to the flowchart of FIG. 12. However, by executing the nurse terminal calling order storage unit generation process, the fixed patient terminal 100 or the moving patient terminal 200 is performed. In response to the nurse call from the nurse, the calling order of the nurse terminal 130 indicating the order to be dealt with is generated, and as shown in FIG. 8, the patient terminal 100 or the patient terminal that made the nurse call In association with the patient terminal number indicating 200, it is set in the nurse terminal calling order storage unit 170 (step A30).

  FIG. 8 is a table showing an example of the nurse terminal call order storage unit 170 in the nurse call control device 110 shown in FIG. 1, which has a two-stage table configuration, and the parent table is a patient terminal number 170 a. The child table is composed of the call order nurse terminal link information 170b and is indexed by each call order nurse terminal link information 170b. The call order nurse terminal number 170c0, the call order nurse terminal number 170c1, the call order The example is composed of nurse terminal numbers 170c2,. In the flowchart of FIG. 12 to be described later, the nurse terminal call order storage unit 170 stores the patient terminal 100 or the patient who made the nurse call as the call order of the nurse terminal 130 to respond in response. The operation of creating and registering the order of the nurse terminal 130 in the calling order so that the nurse terminal 130 physically located near the place where the terminal 200 is located is preferentially called. An example is shown.

  That is, in the setting example of the nurse terminal call order storage unit 170 illustrated in FIG. 8, the nurse terminals 130 are identified in the order physically close to the patient terminal 100 or the patient terminal 200 that made the nurse call. The nurse terminal number is set and registered. For example, for the call order nurse, the “call link-0” of the call terminal link information 170b for the patient terminal number 170a of “0” is linked. The terminal number 170c0 is set in the order of "terminal number for nurses-0", "terminal number for nurses-1", "terminal number for nurses -2", ..., "terminal number for nurses-15". When a nurse call is made from the patient terminal 100 of the patient in the patient room 201 of the patient terminal number “0”, nursing that should be responded in the order of the calling terminal number 170c0 for the nurse The teacher terminal 130 It shows an example that has been set to the effect that.

  In addition, the terminal number 170c2 for the call order nurse linked to the “call link-2” of the terminal link information 170b for the call order nurse whose patient terminal number 170a is “2” includes the “terminal number for the nurse”. -2 ',' Nurse terminal number-3 ',' Nurse terminal number-0 ', ...,' Nurse terminal number-15 'are set in this order, and the patient terminal number' 2 ' When there is a nurse call from the patient terminal 100 of a patient in the hospital room 202, it is set that the terminal is a nurse terminal 130 to be responded to in the order of the calling order nurse terminal number 170c2. An example is shown.

  Returning to the description of the flowchart of FIG. 11, next, a method of calling the nurse terminal 30 is checked with reference to a preset calling method (step A40). As a calling method, when performing “simultaneous calling” of all the nurse terminals 130 simultaneously (in the case of “simultaneous” in step A40), refer to the nurse terminal calling order storage unit 170 shown in FIG. The terminal number for the call order nurse registered in association with the patient terminal number of the patient terminal 100 or the patient terminal 200 that made the nurse call, for example, the patient terminal number “2”, for example, for the call order nurse The nurse terminal 130 of the nurse terminal number registered and registered at the top of the terminal numbers 170c2, for example, the nurse terminal 130 of the "nurse terminal-2" is to be dealt with with the highest priority. Are extracted as a nurse terminal 130.

  For the extracted nurse terminal 130, as shown in FIG. 9A or FIG. 9B, the nearest nurse terminal 130 to be most preferentially dealt with in the closest physical location. Special character information determined in advance as a screen (step A50), and a predetermined special ringtone is output to notify the nurse carrying the nurse terminal 130 (step A70). . At this time, in step A21 or step A23, the nurse obtained by referring to the patient terminal (for fixation) location information list 180 in FIG. 4 or the patient terminal (for movement) location information list 190 in FIG. The location information of the patient terminal 100 or the patient terminal 200 that made the call is also displayed on the nurse terminal 130 and notified to the nurse (step A50).

  In addition, as shown in FIG. 9C, a special calling method is provided for the nurse terminal 130 that is set and registered after the second call number nurse terminal number 170c2. Without displaying the character information on the screen, the location information where the patient terminal 100 or the patient terminal 200 where the nurse call was made, acquired in step A21 or step A23, is displayed on the screen (step A60). A predetermined ringtone is output for use and notified to the nurse (step A70). In other words, in the case of “simultaneous calling”, special character information indicating that it is nearest to the nearest nurse terminal 130 and location information on the patient are displayed on the screen, and then the nearest ringtone is used. In addition, for other non-nearest nurse terminals 130, information on the location of the patient is displayed on the screen, and then all nursing care accommodated in the nurse call control device 110 is used by using a normal ringtone. The teacher terminals 130 are simultaneously called simultaneously (step A70).

  Also, as a calling method, when performing “time difference calling” in which all the nurse terminals 130 are called sequentially with a predetermined time difference instead of simultaneously (in the case of “time difference” in step A40), a nurse call is made. An operation of sequentially calling the nurse terminal 130 is performed with a predetermined time difference in order of physical proximity to the performed patient terminal 100 or patient terminal 200.

  Therefore, among the call order nurse terminal number 170c0, the call order nurse terminal number 170c1, the call order nurse terminal number 170c2,... In the nurse terminal call order storage unit 170 shown in FIG. Called terminal number 100 for patient or terminal number 200 for patient corresponding to terminal 100 for patient corresponding to patient terminal 100 of terminal number “0” for patient, for example, call for indexing within terminal number 170c0 for calling order The forward index “I” is initially set to “0” so that the nurse terminal 130 located at the closest physical location is extracted first (step A51). Thereafter, a designated nurse terminal calling process for sequentially calling the nurse terminals 130 designated by the call order index index “I” updated by “+1” for each predetermined time difference is performed (steps). A52).

  Here, details of the designated nurse terminal calling process will be described later with reference to the flowchart of FIG. 13. In the designated nurse terminal calling process, first, the patient terminal 100 or the patient who made the nurse call Initial setting of a call order index for index number 'I' for indexing the call number nurse terminal number, for example, the call order nurse terminal number 170c0 corresponding to the patient terminal 100 having the patient terminal number '0' for the patient terminal 200 Using the value, the nurse call was made in step A21 or step A23, where special character information indicating the number of calls made to the extracted nurse terminal 130 was acquired. Special information indicating the order of calling after displaying the screen together with the location information where the patient terminal 100 or the patient terminal 200 is located A beep sound is output and reported to the nurse carrying the nurse terminal 130.

  Thereafter, each time a predetermined time elapses, the call order index index “I” is incremented by “+1”, and the call order nurse terminal number, for example, the call order nurse terminal number 170c0 is indexed. In step A21 or step A23, the nurse terminal 130 in the next order is extracted, and special character information indicating the number of calls to the extracted nurse terminal 130 is obtained. The nurse terminal 130 or the patient terminal 200 that made the nurse call is displayed on the screen together with the location information where the patient terminal 200 is located, and then a special ring tone indicating the order of calling is output, and the nurse terminal 130 is output. The process of reporting to the nurse carrying the is repeated until the calling operation for all the nurse terminals 130 is completed.

  By performing such processing, the nurse terminal 130 is sequentially called with a predetermined time difference in order of physical proximity to the patient terminal 100 or the patient terminal 200 that made the nurse call.

  The details of the calling method of “simultaneous calling” and “time difference calling” will be described with reference to the flowchart of FIG. 12, but the location of the patient terminal 100 or the patient terminal 200 that made the nurse call is located. The nearest nurse terminal 130 of the nearest nurse is not available for receiving calls, but is in a busy state or is unable to receive calls (incoming call rejection or power off state) Etc.), the nurse terminal 130 that is ready to receive the call is placed in the order of the nurse terminal 130 that is close to the location where the patient terminal 100 or the patient terminal 200 is located. It searches and operates to call the nearest nurse terminal 130 among the available nurse terminals 130 as the nearest nurse terminal 130. .

  Further, when the type of patient terminal that has made a nurse call is the moving patient terminal 200, the patient terminal 200 can be used in any of the “simultaneous calling” and “time difference calling” calling methods. When the nurse call control device 110 stores in advance information on who is carrying the patient and makes a nurse call using the patient terminal 200 for movement, in step A50 and step A60, It is desirable that the name of the patient who made the nurse call using the moving patient terminal 200 is also displayed on the screen for the nearest nurse terminal 130 and all other nurse terminals 130.

  Next, a display example of character information displayed on the nurse terminal 130 and a type of ringtone to be output when calling to the nurse terminal 130 will be described with reference to the schematic diagram of FIG. FIG. 9 is a diagram for explaining an example of character information displayed on the screen of the nurse terminal 130 and a ringtone output from the nurse terminal 130 when a call is made from the patient terminal 100 or the patient terminal 200. FIG. In the schematic diagram of FIG. 9, FIG. 9 (A) shows the location of the “physical call” all nurse terminals simultaneous call method, physically located closest to the fixed patient terminal 100 that made the nurse call. An example of a screen display and a ring tone for the nurse terminal 130 of the nurse to be performed is shown. For example, in the case of a nurse call from the patient terminal 100 for fixing a patient admitted to the hospital room 203 , 'You are closest to the nurse's terminal 130 closest to the hospital room 203! The special character information “'is displayed on the screen together with the location information“ hospital room 203 ”, and a predetermined ring tone is output for the nearest use.

  FIG. 9B is a diagram for nurses of nurses who are physically located closest to the patient terminal 200 for movement in which a nurse call is made in the “simultaneous calling” all-terminals simultaneous calling method for nurses. For example, in the case of a nurse call from a patient terminal 200 carried by a patient in a toilet on the third floor, nursing is performed at a place closest to the toilet. 'You are close to the teacher's terminal 130! Special character information “'is displayed on the screen together with location information“ near the third-floor toilet ”and information indicating the name of the patient carrying the moving patient terminal 200“ Mr. Tanaka ”. Output a ringtone.

  FIG. 9C shows an example of a screen display and an incoming call when a normal nurse terminal 130 other than the nearest nurse terminal 130 is called in the “simultaneous call” all nurse terminals simultaneous call method. A sound is illustrated, and only the location information of “hospital room 203” is displayed on the screen as character information, and a predetermined ringtone is output as a normal ringtone.

  In addition, in the time difference calling method in which the nurse terminal 130 is sequentially called in order by providing a predetermined time difference as “time difference calling”, the nurse terminal 130 to be responded first and to respond first (first The nurse terminal 130 that makes a call is the nurse terminal 130 of the nurse that is physically located closest to the patient terminal 100 or the patient terminal 200 that made the nurse call. As in the case of the nearest call in “calling”, the screen display example and the ring tone for the nurse terminal 130 perform the same incoming operation as in FIG. 9A or FIG. 9B.

  On the other hand, with respect to the screen display and the ring tone for the second and subsequent calling orders in “time difference calling”, the character information indicating the calling order (that is, the order close to the patient who made the nurse call) is previously stored. Attached as predetermined special character information, is displayed on the screen together with the location information of the terminal 100 for the patient who made the nurse call, and further, a ring tone indicating the order is output as a predetermined special ring tone. For example, the screen display example for the nurse terminal 130 in the second calling order and the ring tone, as shown in FIG. 9 (D), 'You are the second! The special character information “'is displayed on the screen together with the location information“ hospital room 203 ”, and a special ring tone predetermined for the second use is output.

  As described above, each nurse is present in preparation for a case where a patient admitted to a medical institution such as a hospital tries to call a nurse using the patient terminal 100 or the patient terminal 200 in an emergency. The location (position) was collected periodically whenever a location movement occurred or at predetermined intervals, and a nurse call was made when calling each nurse's terminal carried by each nurse. In accordance with the positional relationship between the patient and the nurse, the character information displayed on the screen of each nurse terminal and the ringtone to be output are changed.

  More specifically, when calling a nurse, the nearest nurse to the nurse terminal 130 carried by the nearest nurse who is present at the nearest position of the patient who made the nurse call. Using special text information display and special ringtone that can clearly indicate that the call should be answered positively so that the nurse can recognize that it should respond By calling, the nurse is notified that he / she is the closest among the plurality of nurses.

  In addition, the nurse terminal 130 of the nurse that is closest to the patient who made the nurse call is in a busy state, not available for receiving calls, or for handling other patients. Even if there is a state where it is not possible to respond to a call (a state where incoming calls cannot be received such as an incoming call refusal state or a power-off state), it is next to the patient who made the nurse call. If the nurse's nurse terminal 130 is ready to receive a call, the next nearest nurse is regarded as the nearest nurse who should respond to the patient's call, and a special character is written to that effect. Notification is also possible using information display and a special ringtone.

  Thus, a nurse who has received a notification using a special text information display and a special ringtone that explicitly indicates that he is closest, is in the position closest to the patient who made the nurse call, It is possible to surely recognize that the patient is a nurse to handle the patient, respond positively to the patient's call, and promptly contact the patient who made the nurse call. Can move to the patient who made the nurse call.

(Example of operation for generating call order of nurse terminals)
Next, an example of the nurse terminal call order storage unit generation process shown in step A30 of the flowchart of FIG. 11 will be described in detail with reference to the flowchart of FIG. FIG. 12 is a flowchart for explaining an example of an operation for generating the setting information of the nurse terminal calling order storage unit 170 shown in FIG. 8. The patient terminal 100 for fixation or the patient terminal 200 for movement is shown in FIG. In response to a call from the nurse, a call order of the nurse terminal 130 to be responded to is generated, and associated with the patient terminal number indicating the patient terminal 100 or the patient terminal 200 that has made the nurse call, An operation example set in the nurse terminal calling order storage unit 170 in FIG. 8 will be described. That is, as described above, priority is given to the nurse terminal 130 of the nurse that is physically located near the place where the patient terminal 100 or the patient terminal 200 that made the nurse call is located. As shown in FIG. 8, the nurse terminal numbers are stored in order of increasing physical distance from the patient terminal 100 or the patient terminal 200 that made the nurse call. Is set.

  When the flowchart of FIG. 12 is started, first, a near-order index index 'N' used for indexing each of the close order CS numbers 160c0 to 160c7 in the close order CS number list 160 shown in FIG. The call order index index 'I' used for indexing each of the call order nurse terminal numbers 170c0, 170c1, ... in the nurse terminal call order storage unit 170 shown is for the patient who made the nurse call. Initialization is set to “0” so that the nurse terminal 130 located at the location physically closest to the terminal 100 or the patient terminal 200 is first extracted (step B10).

  Here, FIG. 10 is a table showing an example of a near-order CS number list 160 in the nurse call control device 110 shown in FIG. 1, which has a two-stage table structure, and the parent table is the CS number of the base station number. It shows an example in which a child table indexed by each close order CS number link information 160b is composed of a close order CS number 160c0 to a close order CS number 160c7. In the close order CS number list 160, the base station numbers (CS numbers) of the local base stations 120 are preset for each local base station 120 in the order in which the physical distance between the local base stations 120 is short. It is registered.

  That is, in the setting example of the close order CS number list 160 illustrated in FIG. 10, for example, the close order in which the “close order link-0” of the close order CS number link information 160 b in which the CS number 160 a is “0” is linked. The CS number 160c0 includes' CS-0 ',' CS-1 ',' CS- in order of increasing physical distance from the local base station 120 having the base station number (CS number) of '0'. In this example, 2 ′,..., “CS-7” and base station numbers (CS numbers) for specifying the local base stations 120 are set and registered in advance.

  In addition, the base station number (CS number) is “7” in the close order CS number 160c7 to which the “close order CS-7” of the close order CS number link information 160b having the CS number 160a of “7” is linked. Specify 'CS-7', 'CS-6', 'CS-5', ..., 'CS-3' and each local base station 120 in order of increasing physical distance to the local base station 120. In this example, base station numbers (CS numbers) to be set are registered in advance.

  Returning to the description of the flowchart of FIG. 12, whether or not all the base station numbers (CS numbers) in the near order CS number list 160 have been checked with reference to the near order index index “N”. (Step B20). If all of the base station numbers (CS numbers) have been checked (YES in step B20), the generation processing of all information to be set in the nurse terminal calling order storage unit 170 has been completed. Then, the flowchart of FIG.

  On the other hand, if the check for all of the base station numbers (CS numbers) has not been completed yet (NO in step B20), it has been acquired in step A20 or step A22 of the flowchart of FIG. Using the nearest base station number (CS number) that identifies the local base station 120 whose physical distance is closest to the place where the patient terminal 100 or the patient terminal 200 that made the nurse call is located, for example, the base station number (CS number) '0' is used to link the 'close order link-0' in the close order CS number link information 160b in the close order CS number list 160b in the close order CS number list 160 of FIG. The Nth base station number (CS number) indicated by the near-order index index “N” is acquired by referring to the near-order CS number 160c0 (step B30). At the initial setting of the index “N” for the near-order index, the 0th base station number (CS number), that is, the base station number (CS number) that identifies the nearest private base station 120, for example, the base station number (CS number) “0” 'Will be acquired.

  Next, an accommodation index index 'M' used for indexing each of the accommodation nurse terminal numbers 150c0 to 150c7 of the accommodation nurse terminal number storage unit 150 shown in FIG. Step B40). Thereafter, using the Nth base station number (CS number), for example, the base station number (CS number) “0” indicated by the near forward index index “N” obtained in step B30, it is shown in FIG. The terminal number for the housing nurse linked to the terminal link information 150b for the housing nurse in the CS number 150a of the terminal number storage unit 150 for the housing nurse is referred to, for example, the terminal number 150c0 for the housing nurse. In the terminal number, for example, the accommodation nurse terminal number 150c0, the M-th nurse terminal number indicated by the accommodation index index 'M' is extracted (step B50).

  Next, the nurse terminal 130 accommodated in the local base station 120 indicated by the N-th base station number (CS number) indicated by the near sequential index index “N”, for example, the base station number (CS number) “0”. It is confirmed whether or not the M-th nurse terminal number taken out in step B50 is present for the terminal number for nursing nurses, for example, the terminal number 150c0 for nursing nurses (step B60).

  If the terminal number for the nurse at the Mth (at the time of initial setting, for example, the 0th head at the beginning of the terminal number 150c0 for the registered nurse) does not exist (NO in step B60) The wireless communication area of the local base station 120 having the Nth base station number (CS number), for example, the base station number (CS number) “0” indicated by the near-index index “N”, is currently used for nurses. It is determined that the terminal 130 is not present. Therefore, whether or not the nurse terminal 130 is accommodated in the local base station 120 that is disposed at a location closest to the next physical distance from the patient terminal 100 or the patient terminal 200 that made the nurse call. In order to confirm, “+1” is added to the near index index “N” (step B61), and the process returns to step B20.

  On the other hand, if there is an M-th terminal number for the nurse (at the time of initial setting, for example, the 0th head at the beginning of the terminal number 150c0 for the registered nurse) (YES in step B60) ), The nurse terminal 130 is located in the wireless communication area of the local base station 120 having the Nth base station number (CS number) indicated by the near-order index index “N”, for example, the base station number (CS number) “0”. In this case, it is confirmed whether or not the nurse terminal 130 of the Mth (0th at the initial setting) nurse terminal number is ready to receive a call (step B70). That is, it is confirmed whether the nurse terminal 130 is in a state where it can receive an incoming call, not in a calling state, a calling state, an incoming call rejection state, or a power-off state.

  If the nurse terminal 130 with the M-th (0th at initial setting) nurse terminal number is not ready to be received (NO in step B70), the nurse terminal 130 is called. In the wireless communication area of the local base station 120 of the Nth base station number (CS number), for example, the base station number (CS number) “0”, indicated by the near forward index index “N”. In order to confirm whether or not the other nurse terminal 130 in the area is still present, the accommodation index index “M” is incremented by “+1” (step B71), and the process returns to step B50. .

  On the other hand, when the nurse terminal 130 of the Mth (0th at the initial setting) nurse terminal number is ready to be received (YES in step B70), the nurse terminal 130 is concerned. , The nurse terminal number of the nurse terminal 130 is changed to the call order nurse terminal numbers 170c0, 170c1, the nurse terminal call order storage unit 170 shown in FIG. ... of the calling order nurse terminal number for setting and registering the calling order related to the patient terminal 100 or the patient terminal 200 that made the nurse call, for example, the calling order index index in the calling order nurse terminal number 170c0 ' It is set and registered at the Ith (0th in the initial state) indicated by I ′ (step B80). In other words, as the nurse terminal 130 in which the calling order has the highest priority, 0th at the time of initial setting is the nearest nursing that has the closest physical distance to the patient terminal 100 or the patient terminal 200 that made the nurse call. The nurse terminal number of the nurse terminal 130 is set and registered.

  Thereafter, the call order index index “I” is set to “+1” in order to update to the next set registration position of the nurse terminal number in the call order nurse terminal number, for example, the call order nurse terminal number 170c0. 'Addition (step B90), and wireless communication of the local base station 120 of the Nth base station number (CS number) indicated by the near forward index index' N ', for example, base station number (CS number)' 0 ' In order to check whether or not there is still another nurse terminal 130 that is in the area, the accommodation index index 'M' is incremented by "+1" (step B71), and then to step B50. Return.

  As described above, the N-th base station number (CS number) indicated by the near sequential index index “N”, for example, the base station number (CS number) “0” is located in the wireless communication area of the local base station 120. Until the next nurse terminal 130 disappears, the accommodation index index 'M' and the call order index index 'I' are incremented by '+1', and the nurse terminal call order storage unit 170 in FIG. 8 is added. Repeat the operation for setting and registering the nurse terminal number at the same time, and add the near-order index index “N” by “+1” until the same setting registration operation is completed for all the local base stations 120. Then, by repeating the operation of setting and registering the nurse terminal number in the nurse terminal call order storage unit 170 of FIG. 8, the nurse terminal call order storage unit 170 stores the nurse call number for the patient who made the nurse call. end Nurse terminal number of physical nurse terminal 130 of the distance that can be called in order of closeness state is to be sequentially set and registered with respect to 100 or patient terminal 200.

(Example of time difference calling operation of designated nurse terminal)
Next, an example of the designated nurse terminal calling process shown in step A52 of the flowchart of FIG. 11 will be described in detail with reference to the flowchart of FIG. FIG. 13 is a flowchart for explaining an example of an operation of sequentially specifying the nurse terminal 130 that should respond to a call from the patient terminal 100 or the patient terminal 200 and performing a time difference call, as shown in FIG. Referring to the setting information in the nurse terminal calling order storage unit 170, the nurse terminal to respond in response to the nurse call from the fixed patient terminal 100 or the moving patient terminal 200 An operation example is described in which the designated nurse terminals 130 are called at predetermined time intervals in order of 130 calls. That is, as described above, according to the setting contents of the nurse terminal call order storage unit 170 in FIG. 8, it is physically close to the place where the patient terminal 100 or the patient terminal 200 where the nurse call is made is located. It operates so that the nurse terminals 130 of the nurses existing at the place are called in order of priority.

  In step A51 of the flowchart of FIG. 11, the call order nurse terminal number 170c0, the call order nurse terminal number 170c1, the call order nurse terminal number 170c2, in the nurse terminal call order storage unit 170 shown in FIG. When the flowchart of FIG. 13 is started in the state where the index “I” for calling order index for indexing each of them is initially set to “0”, the terminal calling process for the designated nurse is first forced. The forced end flag for instructing to end is initially set to OFF (step C10). Thereafter, using the value of the index “I” for call order index initialized to “0”, the call order nurse terminal number 170c0 in the nurse terminal call order storage unit 170 shown in FIG. Among the nurse terminal number 170c1, the calling order nurse terminal number 170c2,... The calling order nurse terminal number for setting and registering the calling order related to the patient terminal 100 or the patient terminal 200 that made the nurse call, for example, calling The I-th (0th in the initial state) nurse terminal number in the sequential nurse terminal number 170c0 is acquired as the nurse terminal number indicating the nurse terminal 130 in the I-th calling order ( Step C20).

  Next, in order to call the nurse terminal 130 of the nurse terminal number acquired as the I-th (0th in the initial state) calling order, as shown in the schematic diagram of FIG. First, 'You are close to the Ith! In addition to special character information explicitly in the close order of ', character information indicating the location information of the patient terminal 100 or the patient terminal 200 acquired in step A21 or step A23 of the flowchart of FIG. The screen is displayed on the service terminal 130 (step C30). Further, a special ringing tone that explicitly indicates the I-th calling order (that is, the order close to the I-th order) is output and notified to the nurse carrying the nurse terminal 130. (Step C40).

  Thereafter, in order to extract the nurse terminal 130 of the next calling order from the nurse terminal calling order storage unit 170 shown in FIG. 8, the call order index index “I” is incremented by “+1” (step C50). ). Next, using the call order index index “I” added with “+1”, refer to the call order nurse terminal number of the nurse terminal call order storage unit 170 of FIG. 8, for example, the call order nurse terminal number 170c0. Then, it is confirmed whether or not the nurse terminal number indicating the nurse terminal 130 in the new I-th calling order is set and registered (step C60). If the terminal number for nurse in the new I-th calling order is not set and registered in the nurse terminal calling order storage unit 170 of FIG. 8 (NO in step C60), all the nurse terminals 130 are registered. Since the time difference calling operation is complete, the operation shown in the flowchart of FIG. 13 is terminated.

  On the other hand, if the nurse terminal number for the nurse in the new I-th calling order is registered in the nurse-terminal calling order storage unit 170 of FIG. 8 (YES in step C60), the new I-th calling order After the predetermined time difference elapses for the nurse terminal 130 with the nurse terminal number in the calling order, a call timer is started to make a time difference call (step C70). If the call timer has not reached the predetermined time difference and has not expired (NO in step C80), the call operation for the nurse terminal 130 in the next call order is waited. Then, it is confirmed whether or not the forced end flag has been switched to ON (step S90).

  Here, the forcible end flag is initially set to OFF in step C10. However, if any of the nurse terminals 130 that have already made a call due to a time difference call responds, even if there is still a nurse terminal 130 that has not made a call, it is necessary to make a further time difference call. There is no. Therefore, as will be described later with reference to the flowchart of FIG. 14, when any of the nurse terminals 130 responds, the forced termination flag is set to ON to instruct to terminate the time difference calling operation forcibly. Come on.

  Returning to the description of the flowchart of FIG. 13, when the forced end flag has been switched ON (in the case of ON of Step C90), the time difference calling operation is forcibly ended to perform the operation shown in the flowchart of FIG. Terminate. On the other hand, when the forced end flag is OFF (in the case of OFF of step C90), the process returns to step C80 to repeat the operation of checking whether or not the predetermined time difference has been reached and the call timer has expired.

  If the predetermined time difference has been reached and the call timer has expired (YES in step C80), the time difference for the next time difference call has been reached. In order to perform the calling operation for the nurse terminal 130, the process returns to Step C20.

  By making a time difference call as described above, a plurality of patients at remote locations are determined in advance when calling a nurse using each patient terminal 100 or patient terminal 200 simultaneously. It is possible to call the nurses sequentially in the order of close distance to each patient who made a nurse call at the timing shifted by the time difference. In addition, the place (position) where each nurse is located is collected every time a movement of the place occurs or at a predetermined cycle.

  That is, even if the nurse terminal 130 of each nurse is simultaneously called for a nurse call from a plurality of patients at remote locations, all the nurse terminals 130 of each nurse are first selected. The call state from the other patient cannot be called until one of the nurse terminals 130 responds, but it is shifted sequentially by a predetermined time. By making a time difference call of calling, such a situation can be avoided, and nurses near each patient can be called separately.

  Also, when making a time difference call, each nurse is given the number of the order by displaying a screen of special character information indicating the calling order of each nurse to the nurse terminal 130 and outputting a special ring tone. You can recognize if it is called. Thus, the nurse who is called first can recognize that he is the closest nurse to the patient who made the nurse call and is the nurse who should respond to the patient. By actively responding to the call, it is possible to promptly contact the patient who made the nurse call, and to move quickly to the patient who made the nurse call.

  The nurse terminal 130 is determined in advance according to the order of the nurse terminal 130 set and registered in the nurse terminal call order storage unit 170 shown in FIG. 8 by the time difference call shown in the flowchart of FIG. If any of the calling nurse terminals 130 responds in the middle of repeating the calling operation sequentially for each time difference, as described above, it is assumed that the nurse terminal 130 that has not been called still remains. However, it is not necessary to repeat the call every time a predetermined time difference elapses. Therefore, when any of the called nurse terminals 130 responds, the flowchart shown in FIG. 14 is activated. FIG. 14 illustrates an operation in the case where any of the nurse terminals 130 that has already called up responds while the time difference calls of the nurse terminal 130 are being performed for each predetermined time difference in the calling order. It is a flowchart for.

  When any of the nurse terminals 130 that have already called up responds while calling the time difference of the nurse terminal 130 for each predetermined time difference in the calling order, the remaining nurse terminals Although there is no need to make a further call to 130, since the call timer is activated in step C60 of FIG. 13, the call timer is first set as shown in the flowchart of FIG. Stop (step D10). Furthermore, in order to forcibly end the designated nurse terminal calling process of FIG. 13, the forced end flag is set to ON (step D20), and then the operation of the flowchart of FIG. 14 ends.

  In the time difference calling flowchart shown in FIG. 13, when calling each nurse terminal 130, the calling order (that is, the order close to the patient terminal 100 or the patient terminal 200 that made the nurse call) is shown. Although the case where the screen display of the special character information shown and the output of the special ringtone are described has been described, depending on the case, the nearest nurse terminal 130 is shown in FIG. 9 (A) or FIG. 9 (B). As shown in FIG. 9C, a special character information screen display indicating that it is the nearest and a special ring tone are output. Character information screen display and normal ringtone output may be performed.

  In the above description of the embodiment, the case where the PHS terminal is used as the nurse terminal 130 or the mobile patient terminal 200 and the PHS base station is used as the local base station 120 has been described. This is not the only case. For example, a wireless LAN terminal (wireless LAN slave device) may be used as the nurse terminal 130 or the mobile patient terminal 200. In such a case, a wireless LAN access point (parent station) is used as the local base station 120. Will be used.

(Explanation of effect of embodiment)
As described in detail above, the nurse call system according to the present embodiment can provide the following effects.

  First, based on the positional relationship between the nurse who made the nurse call and each nurse, the nurse terminal 130 carried by the nurse closest to the place of the patient who made the nurse call Because it is possible to make calls by displaying special character information on the screen and outputting a special ring tone, it is possible for the nearest nurse to call the patient who made the nurse call. It is possible to reliably recognize that the nurse is closest and should respond in response to the patient's call. Thus, the nurse closest to the patient who made the nurse call can respond with a positive awareness that he is the nurse he should respond to. It is possible to move quickly to the patient who performed.

  Second, based on the positional relationship between the patient who made the nurse call and each nurse, each nurse was shifted by a predetermined time difference in the order of the nurse who was near the place of the patient who made the nurse call. It is also possible to sequentially call the nurse terminals 130 carried by. Thus, when a plurality of patients at remote locations try to call a nurse at the same time, unlike when simultaneously calling all the nurse terminals 130 for each nurse, Since nurses close to the patient can be called separately, different nurses can quickly move to each patient.

  In the description of the present embodiment, the case where the present invention is applied to a nurse call in a medical institution such as a hospital has been described. However, the present invention can also be used for emergency contact other than in a medical institution in some cases. . For example, when applied to an accommodation facility such as a hotel, when there is a boy dispatch request to the front from a customer staying in a certain guest room, the front of the boy's communication terminal in the vicinity of the guest room It is also possible to get in touch and send the nearest or next closest boy to the room. Alternatively, it can be applied to a company, a factory, etc. and used for emergency contact with a person in charge when a problem occurs.

  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.
