Description

  The present invention relates to a nurse call system, and is particularly suitable for use in a nurse call system in which a mobile terminal for notifying a nurse of a call from a patient is shared by a plurality of nurses.

  In general, the nurse call system is configured to include a nurse call slave unit used by a patient and a nurse call master unit installed at a nurse center. There is also provided a nurse call system further equipped with a portable terminal carried by a nurse. In this type of nurse call system, when a patient presses a call button of a nurse call slave unit to make a call, it is notified that the call is made by the nurse call master unit or the portable terminal .

  In a nurse call system employing a portable terminal, a function is also provided, in which a call from one patient is notified to a plurality of portable terminals, and a nurse who first responds with the portable terminal can talk with the patient. Such a function is used, for example, when performing team nursing where one nurse is supported by a plurality of nurses. In this case, the patient and a plurality of nurses who are in charge of the patient are stored as association information, and when there is a call from the patient, the plurality of nurses in charge are identified by referring to the association information, Call the mobile terminal owned by the nurse in charge.

  Conventionally, a nurse call system is known in which one mobile terminal (wireless slave) is shared by a plurality of nurses with different work zones such as day shift, near night shift, and night shift (see, for example, Patent Document 1) ). In the nurse call system described in Patent Document 1, when the nurse uses the wireless slave device, the nurse user ID is input by inputting the nurse user ID into the wireless handset input device of the wireless slave device. Association data with the extension number of the wireless slave and the nurse's name is created at the nurse call server. As a result, based on the association data, it is possible to record the name of the nurse who uses the wireless slave and the login / logout information of the nurse as working time.

  However, if the nurse forgets to log in by entering the user ID, even if the patient presses the call button of the nurse call slave unit to make a call, the call is not made to the mobile terminal that has not been logged in. . Here, if there are not many portable terminals logged in in the same team, the number of nurses in charge of responding to calls from patients decreases. And, when those nurses in charge are engaged in other nursing services when the call occurs, there is a problem that the response to the call is delayed or can not be answered, and the patient is kept waiting.

  With respect to such a problem, there is known a technology in which a call is made to a mobile terminal in a state of not logging in in addition to the mobile terminal that has logged in (see, for example, Patent Document 2). In the nurse call system described in Patent Document 2, when login authentication is performed, the extension number of the nurse is transmitted to the mobile terminal and the extension number is set for the mobile terminal that has not been authenticated. Can not be called by Therefore, the terminal ID is regarded as an extension number, and calling is performed.

  Specifically, referring to the patient table in which the nurse call child machine and the patient are associated with each other and the patient / terminal information in which a plurality of portable terminals are associated for each patient, the nurse call child machine to which the call is made is supported. Specify the terminal ID to be implemented and make a call. However, when there is even one portable terminal that has been authenticated for login, a call signal is first transmitted to the portable terminal, and if there is no response after a predetermined time has elapsed, then the portable terminal that has not been authenticated for login Also sends a ringing signal to.

  However, in the technology described in Patent Document 2, in addition to the login-authenticated mobile terminal, a mobile terminal that is not login-authenticated is called. Therefore, if the nurse at the previous work area forgets to log out of the mobile terminal, and the nurse who uses the mobile terminal next forgets to log in, the patient who is in charge of the nurse who has forgotten to log in There was a problem that the call was not made to the portable terminal.

  The present invention has been made to solve such problems, and a nurse using a portable terminal in a nurse call system configured to share one portable terminal among a plurality of nurses. An object of the present invention is to ensure that a call from a patient can be notified to a portable terminal of a nurse in charge even if the user has forgotten to log in.

  In order to solve the problems described above, according to the present invention, when a call from a patient is made, in addition to the nurses in charge of the patient performing the call to the portable terminal currently logged in, the patient The nurse in charge logs in and specifies a portable terminal that can be used, and among the specified portable terminals, the nurse in charge executes a call to a portable terminal other than the portable terminal currently logged in. Furthermore, the present invention is provided with a work area information storage unit that stores a work area for each nurse, and is logging in by login information stored when login is performed by inputting a nurse ID from a portable terminal. Among the nurses who are shown, it specifies an overtime nurse who is a nurse whose current time does not belong to the range of the working hours stored in the working time information storage unit, and the overtime nurses Identifies the logged-in mobile terminal from the login information and executes the call.

  According to the present invention configured as described above, even if the nurse possessing the portable terminal has forgotten to log in, the portable terminal capable of using the nurse in charge of the patient who made the call can use the logged-in state. The call is also made to the non-mobile terminal. In addition, even if the nurse who used the portable terminal possessed by the nurse has forgotten to log out and is still logged in, the portable terminal is used as a portable terminal for which the overtime nurse is logging in. The call is also made to the portable terminal. As a result, even if the nurse who uses the portable terminal forgets to log in, it is possible to reliably notify the call from the patient to the portable terminal of the nurse in charge.

When the nurse starts using the mobile terminal 10 (at the start of work), the mobile terminal 10 is operated to log in to the nurse call system. Further, when the nurse finishes using the mobile terminal 10 (at the end of work), the mobile terminal 10 is operated to log out of the nurse call system.

  FIG. 2 is a block diagram showing an example of a functional configuration of the nurse call master device 1 according to the present embodiment. As shown in FIG. 2, the nurse call master device 1 according to the present embodiment has, as its functional configuration, a login processing unit 101, a call receiving unit 102, a nurse-in-charge specifying unit 103, a first terminal specifying unit 104, a first The second call processing unit 105, the second call identification unit 106, the second call processing unit 107, the after-hour nurse identification unit 108, the third call identification unit 109, and the third call processing unit 110 are provided. In addition, the nurse call master device 1 of the present embodiment is used as a storage medium for storing various information, such as a patient information storage unit 121, a nurse in charge storage unit 122, a contact destination storage unit 123, a terminal information storage unit 124, attendance information storage. A section 125 and a login information storage section 126 are provided.

  Each of the functional blocks 101 to 110 can be realized by any of hardware configuration, DSP (Digital Signal Processor), and software. For example, in the case of software implementation, each of the functional blocks 101 to 110 is actually configured by including a computer CPU, MPU, RAM, ROM, etc., and can be implemented by operating programs stored in the RAM or ROM. .

  The patient information storage unit 121 includes information on the patient (name, age, gender, symptoms, room number of the room, bed number identifying the bed used by the patient, patient ID for identifying the patient, nurse call used It stores various information such as a handset ID for identifying the handset 5). In addition, as information for realizing the operation of the present embodiment, as shown in FIG. 3, it is sufficient if there is information in which at least a patient ID and a child device ID are associated.

  The assigned nurse storage unit 122 stores assigned nurse information in which the patient and the assigned nurse are associated with each other. For example, as illustrated in FIG. 4, the in-charge nurse storage unit 122 associates and stores a patient ID for identifying a patient and a nurse ID for identifying the in-charge nurse of the patient. When one patient is in charge of multiple nurses (when team nursing is performed), multiple nurse IDs are associated with one patient ID.

  The contact point storage unit 123 stores contact point information in which a nurse is associated with information (such as an extension number) on the contact point of the portable terminal 10 possessed by the nurse. For example, as illustrated in FIG. 5, the contact storage unit 123 associates and stores a nurse ID for identifying a nurse and the extension number of the portable terminal 10 used by the nurse.

  The terminal information storage unit 124 stores information of the portable terminal 10 that the nurse can log in to the nurse call system and use. As described above, in the present embodiment, one mobile terminal 10 is shared by a plurality of nurses, but the mobile terminal 10 that can be used by one nurse is limited. For example, as illustrated in FIG. 6A, the terminal information storage unit 124 may use a nurse ID for identifying a nurse as information for indicating which nurse can use which portable terminal 10. And the terminal ID for identifying the portable terminal 10 that the nurse can use, in association with each other and stored. When a plurality of portable terminals 10 that can be used are assigned to one nurse, a plurality of terminal IDs are associated with one nurse ID.

  In addition, as shown in FIG. 6B, the terminal information storage unit 124 uses a terminal ID for identifying the portable terminal 10 as information for indicating which portable terminal 100 is shared by which nurse, A nurse ID for identifying a plurality of nurses who share the mobile terminal 10 may be associated and stored.

  The attendance information storage unit 125 stores attendance information of each nurse. In the present embodiment, information indicating a work period (day shift, near-night shift, night shift, etc.) is stored for each nurse. Here, it is assumed that working hours (working start time and working ending time) in the case of daily work, working hours in the case of semi-night work, and working time in the case of night work are determined in advance.

  The login information storage unit 126 stores information on the nurse who is logging in to the nurse call system. For example, as shown in FIG. 6, the login information storage unit 126 includes a nurse ID for identifying a nurse who is logging in and a terminal ID for identifying a portable terminal 10 that the nurse used for logging in. And the extension number which is the contact point of the nurse in association with each other.

  When login is performed by inputting the nurse ID from the portable terminal 10, the login processing unit 101 associates the portable terminal 10 with the nurse who logged in and stores it in the login information storage unit 126 as login information. Let Specifically, the nurse performs login from the portable terminal 10 by inputting the nurse ID. The portable terminal 10 transmits the input nurse ID and its own terminal ID to the nurse call master device 1 to request a login process.

  The login processing unit 101 of the nurse call master device 1 refers to the terminal information storage unit 124 based on the nurse ID and the terminal ID received from the portable terminal 10, and the portable terminal 10 for which the use is permitted for the nurse It authenticates whether login is performed from. Then, when the authentication is successful, the login processing unit 101 refers to the contact storage unit 123, and acquires the extension number that is the contact of the nurse who has logged in.

  Then, the login processing unit 101 associates the nurse ID, the terminal ID, and the extension number, and stores them in the login information storage unit 126 as login information. Also, the login processing unit 101 transmits the acquired extension number to the portable terminal 10 that has logged in. The mobile terminal 10 sets the extension number acquired from the nurse call master unit 1. As a result, the portable terminal 10 is ready to receive a call from the nurse call base unit 1 using this extension number.

  The call reception unit 102 receives a call from the nurse call slave unit 5 and performs a predetermined notification process in the nurse call master unit 1. That is, the call reception unit 102 receives a call signal sent from the nurse call slave 5 via the hallway light 3 and the controller 2. Then, based on the child device ID transmitted by the received call signal, the patient information storage unit 121 is referenced to specify the patient ID of the patient who made the call. Further, patient information corresponding to the identified patient ID is displayed on a display (not shown), and a ringing tone is output from a speaker (not shown).

  When the call from the patient is made (when the call reception unit 102 receives a call signal from the nurse call slave 5), the nurse-in-charge identification unit 103 refers to the patient information storage unit 121. Then, based on the patient ID identified from the child machine ID, the nurse in charge of the patient who made the call is identified by referring to the nurse-in-charge storage unit 122 (acquires the nurse ID).

  The nurse-in-charge storage unit 122 stores the child machine ID for identifying the nurse call child machine 5 used by the patient in association with the nurse ID for identifying the nurse in charge of the patient. It may be In this case, the nurse-in-charge identification unit 103 refers to the nurse-in-charge storage unit 122 based on the child machine ID transmitted by the call signal received by the call reception unit 102, and takes charge of care of the patient who made the call. Identify the master.

  The first terminal identification unit 104 is identified by the assigned nurse identification unit 103 by referring to the login information storage unit 126 based on the nurse ID of the assigned nurse identified by the assigned nurse identification unit 103. Among the nurses in charge, the mobile terminal 10 of the nurse who is logged in to the nurse call system is identified. Here, the first terminal identification unit 104 acquires, from the login information storage unit 126, the extension number of the portable terminal 10 currently used by the nurse in charge of logging in to the nurse call system.

  The first call processing unit 105 executes a call to the portable terminal 10 identified by the first terminal identification unit 104. That is, the first call processing unit 105 makes a call to the portable terminal 10 using the extension number acquired by the first terminal identification unit 104.

  The second terminal specifying unit 106 is in charge of the charge specified by the nurse-in-charge specifying unit 103 when a call from a patient is made (when the call receiving unit 102 receives a call signal from the nurse call slave 5). By referring to the terminal information storage unit 124 based on the nurse ID of the nurse, the portable terminal 10 that can be used by the nurse in charge of the patient who made the call is specified (acquiring the terminal ID of the portable terminal 10 ).

  The second call processing unit 107 calls the portable terminal 10 other than the portable terminal 10 identified by the first terminal identification unit 104 among the portable terminals 10 identified by the second terminal identification unit 106. Run. Here, if all the nurses in charge of the patient who made the call are logging in, the portable terminal 10 used by those nurses in charge is identified by the first terminal identification unit 104, so the second The call processing unit 107 does not call.

  On the other hand, if a nurse in charge forgets to log in, the mobile terminal 10 that can be used by the nurse in charge is identified by the second terminal identification unit 106, and the call to the identified mobile terminal 10 is This is executed by the second call processing unit 107. In this case, since the portable terminal 10 has not logged in, the extension number can not be used. Therefore, the second call processing unit 107 executes the call with the terminal ID of the portable terminal 10 acquired by the second terminal identification unit 106 from the terminal information storage unit 124 as the destination.

  Among the nurses who are indicated by the login information stored in the login information storage unit 126, the overtime nurse identification unit 108 stores the work hours stored in the work area information storage unit 125. Identify nurses who do not belong to the current time (hereinafter referred to as overtime nurses). The nurse usually logs out at the end of working hours. However, if a nurse forgets to log out of the portable terminal 10 and another nurse who is using the same portable terminal 10 next forgets to log in, the login information storage unit 126 works The login information of the nurse who should have finished is still stored. The overtime nurse identification unit 108 identifies nurses other than the work period that has forgotten such a logout.

  That is, the overtime nurse identification unit 108 acquires the nurse ID stored in the login information storage unit 126, and logs in by referring to the work space information storage unit 125 based on the nurse ID. Identify each nurse's work area. Then, the identified work zone is collated with the current time to identify a nurse ID whose current time does not belong within the range of the work zone.

  The third terminal identification unit 109 refers to the login information storage unit 126 based on the nurse ID of the overtime nurse identified by the overtime nurse identification unit 108 so that the overtime nurse logs in. The mobile terminal 10 inside is identified. Here, the third terminal identification unit 109 acquires, from the login information storage unit 126, the extension number of the portable terminal 10 to which the overtime nurse is logging in.

  The third call processing unit 110 executes a call to the portable terminal 10 identified by the third terminal identification unit 109. That is, the third call processing unit 110 makes a call to the portable terminal 10 using the extension number acquired by the third terminal identification unit 109.

  FIG. 8 is a flowchart showing an operation example of the nurse call base unit 1 configured as described above. The process of the flowchart shown in FIG. 8 starts when the nurse call master device 1 receives a call signal from the nurse call slave device 5.

  When the nurse call master unit 1 receives a call signal from the nurse call slave unit 5, first, the call reception unit 102 refers to the patient information storage unit 121 based on the slave unit ID transmitted by the received call signal. Thus, the patient who made the call is identified (step S1). Furthermore, the responsible nurse identification unit 103 identifies the responsible nurse of the patient who made the call by referring to the responsible nurse storage unit 122 based on the patient ID of the patient identified by the call acceptance unit 102 ( Step S2).

  Next, the first terminal identification unit 104 refers to the login information storage unit 126, and among the nurses in charge identified by the nurse identification unit 103 in charge, the portable terminal of the nurse who is logging in to the nurse call system. The terminal 10 is specified, and the internal latitude number of the mobile terminal 100 is acquired from the login information storage unit 126 (step S3). Then, the first call processing unit 105 executes a call by the extension number to the portable terminal 10 identified by the first terminal identification unit 104 (step S4).

  In addition, the second terminal identification unit 106 is in charge of the patient who made the call by referring to the terminal information storage unit 124 based on the nurse ID of the assigned nurse identified by the assigned nurse identification unit 103. The portable terminal 10 which a nurse can use is specified (step S5). Next, the second call processing unit 107 controls the portable terminal 10 other than the portable terminal 10 identified by the first terminal identification unit 104 among the portable terminals 10 identified by the second terminal identification unit 106 It is determined whether there is a mobile terminal 10) to which a nurse has not logged in (step S6).

  Here, when it is determined that there is a portable terminal 10 to which the nurse in charge is not logged in, the second call processing unit 107 executes a call by the terminal ID to the portable terminal 10 to which the login is not logged on ( Step S7). On the other hand, when it is determined that there is no mobile terminal 10 to which the nurse in charge is not logged in, the second call processing unit 107 does not perform the call processing of step S7.

  Next, the overtime nurse identification unit 108 identifies an overtime nurse whose current time does not belong within the range of the working period out of the nurses who are shown to be logging in by the login information ( Step S8). Then, the third terminal specifying unit 109 determines whether the overtime nurse specifying unit 108 specifies the overtime nurse (step S9).

  Here, when the overtime nurse identification unit 108 identifies the overtime nurse, the third terminal identification unit 109 refers to the login information storage unit 126 based on the nurse ID of the overtime nurse. By doing this, the overtime nurse identifies the portable terminal 10 currently logged in (step S10). Then, the third call processing unit 110 executes a call by the extension number to the portable terminal 10 identified by the third terminal identification unit 109 (step S11). Thus, the process of the flowchart illustrated in FIG. 8 is ended.

  On the other hand, when the overtime nurse identification unit 108 does not identify the overtime nurse, the call process of steps S10 and S11 is not performed, and the process of the flowchart illustrated in FIG. 8 is ended.

  As described above in detail, according to the nurse call system of the present embodiment, of the portable terminals 10 that can be used by the nurse in charge of the patient who made the call, the portable terminal 10 not in the login state is the second terminal specification The second call processing unit 107 executes a call to the portable terminal 10 specified by the unit 106 and not logged in. As a result, even if the nurse who holds the shared portable terminal 10 has forgotten to log in, the portable terminal 10 can be called.

  Further, according to the nurse call system of the present embodiment, the third terminal identification unit 109 identifies the portable terminal 10 to which the nurse who is not working is logged in during the non-work hours is identified, and the portable nurse 10 who is logged in after the time. The call is executed by the third call processing unit 110 to the terminal 10. Thereby, another nurse who has used the portable terminal 10 possessed by the nurse forgets to log out, and the nurse who possesses the portable terminal 10 forgets to log in However, it is possible to make a call to the portable terminal 10.

  As described above, according to the nurse call system of the present embodiment, even when the nurse who uses the portable terminal 10 forgets to log in, the call from the patient is reliably notified to the portable terminal 10 of the nurse in charge. be able to.

  In the above embodiment, the processing of the second terminal identification unit 106 and the second call processing unit 107 is performed only when the first terminal identification unit 104 can not identify the portable terminal 10 currently logged in. It may be performed. Similarly, the after-hour nurse identification unit 108, the third terminal identification unit 109, and the third call processing unit are performed only when the first terminal identification unit 104 can not identify the portable terminal 10 currently logged in. The process of 110 may be performed.

  Further, in the above embodiment, an example in which the first call processing unit 105 and the third call processing unit 110 make calls by extension numbers has been described, but the present invention is not limited to this. For example, similarly to the second call processing unit 107, the first call processing unit 105 and the third call processing unit 110 may be configured to make a call using a terminal ID.

  In the above embodiment, the nurse ID and the terminal ID are associated with each other and stored in the terminal information storage unit 124, and the second terminal identification unit 106 determines the nurse in charge identified by the nurse identification unit 103 in charge. Although the example which specifies the portable terminal 10 which the nurse in charge of the patient who made the call can use by referring to the terminal information storage part 124 based on nurse ID of was described, the present invention is limited to this I will not.

  For example, in the terminal information storage unit 124, a patient ID for identifying a patient and a terminal ID of the portable terminal 10 that can be used by the nurse in charge of the patient are stored in association with each other. By referring to the terminal information storage unit 124 on the basis of the patient ID specified by the call reception unit 102, the portable terminal 10 can be used by the nurse in charge of the patient who has made the call. It is also good.

  Further, in the above embodiment, by identifying each work zone of the nurse who is logging in and collating the specified work zone with the current time, a nurse ID whose current time does not belong within the range of the work zone is specified. Although the present invention is not limited thereto. For example, each work zone is provided with an overlapping period of a predetermined time (for example, about 30 minutes), and for the overlapping period, it is assumed that the nurse's work of the workplace before the overlapping period continues.
