Abstract

<P>PROBLEM TO BE SOLVED: To call a medical worker in a normal state as much as possible when calling a plurality of portable terminals for a call by a nurse call slave unit. <P>SOLUTION: The order of calling the portable terminals 30 for a call from a nurse call slave unit 1 is stored in the storage part 14 of a nurse call master unit 10 beforehand, the number of pulses of the medical worker carrying the portable terminal 30 is measured by a pulse sensor 40, and when the number becomes equal to or larger than a prescribed number, the calling order of the portable terminal 30 is delayed. Thus, the portable terminal 30 of the medical worker whose number of pulses is smaller than the prescribed number is preferentially called. Thus, since a call to the medical worker who is not in the normal state is delayed and the medical worker in the normal state is preferentially called, the possibility that the medical worker who responds to the call and copes with a patient causes a medical accident is lowered. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a nurse call system, and is particularly suitable for use in a nurse call system configured to allow a mobile terminal to answer a call with respect to a call from a nurse call slave set installed for each patient.

  In general, a nurse call system is used in hospitals and care facilities. The nurse call system is used when a patient at a hospital needs help from a doctor or nurse, or when a caregiver at a care facility needs help from a caregiver (hereinafter referred to as “patient”). Is a system that can call a doctor, nurse, or caregiver (hereinafter referred to as a health care worker) by pressing a call button or the like.

Many nurse call systems include a nurse call cordless handset installed in a bedside, a toilet, a bathroom, and the like, and a nurse call master set installed in a nurse center. Furthermore, a nurse call system that combines a PHS (Personal Handyphone System) terminal carried by a medical worker and a PBX (Private Branch Exchange: telephone exchange) has also been proposed (see, for example, Patent Document 1).
JP-A-5-259974

  In this type of nurse call system, when a patient makes a call by pressing the call button of the nurse call slave unit, the medical worker responds with a PHS terminal carried by himself or a handset of the nurse call master unit. Note that table information that associates the PHS terminal with the medical staff possessing the PHS terminal is stored in the memory of the nurse call parent device. In other words, since the PHS terminal and the medical staff possessing the PHS terminal have a one-to-one correspondence, the medical staff who has responded to the call from the patient using the PHS terminal is recorded as a response history in the nurse call master unit. It is possible.

  By the way, in the nurse call system as described above, a medical staff in charge is determined for one patient, and the relationship is managed by the table information of the nurse call parent machine. Then, when a call is made from a nurse call cordless handset of a patient, the medical staff in charge is identified with reference to the table information, and the PHS terminal of the medical staff in charge is notified. Therefore, when there is a call from a patient, if the medical worker who has the PHS terminal to be called is absent, the medical worker cannot respond to the call.

However, even in such a case, the nurse call master unit is also notified at the same time, so a medical worker who is not in charge of the patient who is calling the nurse call with the handset provided in the nurse call master unit. Can respond to calls from slave units. In addition, by setting a plurality of PHS terminals to be called or calling a plurality of PHS terminals set as call targets in order, even if the medical staff in charge is absent, A technique for responding to a call is known (see, for example, Patent Document 2).
JP 2001-127892 A

  However, in the technique described in Patent Document 2 described above, the call is also notified to a medical worker who has just responded to a call from a patient or a medical worker who cannot be released during work, There was a problem that stressed medical staff. In addition, the call is also notified to health care workers who are not in a normal state, such as those who are in poor physical condition or are focused on work, so the medical care corresponding to the patient in response to this call There was a problem of increasing the possibility of workers having a medical accident.

  The present invention is made in order to solve such a problem, and a call is made by a nurse call slave unit, and a plurality of medical workers in charge of patients using the nurse call slave unit are respectively provided. The purpose is to call a medical worker in a normal state as much as possible when calling a portable terminal to be carried.

  In order to solve the above-described problems, in the present invention, a mobile terminal to be called in response to a call from a nurse call slave and / or an order of calling the mobile terminal is set in advance in the nurse call parent, The pulse rate of a medical worker to be carried is measured by a pulse sensor, and when the number exceeds a predetermined number, calling to the portable terminal is delayed.

  Further, according to another aspect of the present invention, a mobile terminal to be called in response to a call from the nurse call slave unit and / or an order to call the mobile terminal is set in advance in the nurse call base unit, and the mobile terminal is carried The pulse rate of a health care worker is measured by a pulse sensor, and when the number exceeds a predetermined number, calling to the portable terminal is stopped.

  According to the present invention configured as described above, since the call to the portable terminal carried by the medical worker whose pulse rate is equal to or greater than the predetermined number is delayed, the pulse rate is less than the predetermined number. A mobile terminal carried by a medical worker can be called preferentially. As a result, it is possible to delay a call to a medical worker who is not in a normal state where his / her physical condition is bad or his / her duties are concentrated, and a normal medical worker is called preferentially. Therefore, it is possible to reduce the possibility that a medical worker corresponding to the patient in response to the call will cause a medical accident.

  Moreover, according to the other aspect of this invention, since the call to the portable terminal which the medical worker whose pulse rate became more than predetermined number carries is stopped, the pulse rate is less than predetermined number. Only mobile terminals carried by medical personnel can be called. As a result, it is possible to stop the call to a medical worker who is not in a normal state where the physical condition is bad or the work is concentrated, and the medical worker in a normal state is called. It is possible to reduce the possibility that a medical worker who responds to the patient will cause a medical accident.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a nurse call system according to the present embodiment. Here, a nurse call system for nursing support installed in a hospital will be described as an example, but the nurse call system of the present embodiment is not limited to that installed in a hospital. For example, the present invention can also be applied when installed in a nursing facility.

  As shown in FIG. 1, the nurse call system according to the present embodiment includes a nurse call slave unit 1 installed on each bedside of each hospital room, and a nurse call master unit 10 installed in the nurse center and functioning as a center device. Is provided. Here, the nurse call slave unit 1 and the nurse call master unit 10 are connected to each other via a communication line. In addition, a corridor lamp (not shown) is connected between the nurse call slave unit 1 and the nurse call master unit 10 to notify the call from the nurse call slave unit 1 and to display the name of the patient in the hospital room. Has been.

  The nurse call system according to the present embodiment includes, as other standard components, for example, a main device 20 for a mobile terminal installed in a communication center in a hospital, a PBX (not shown), a public network (not shown), and a wireless device 21 is provided.

  A plurality of wireless devices 21 are connected to the main device 20 for mobile terminals. The PBX is connected to a public network. The main device 20 for mobile terminals is composed of, for example, a private branch PHS compatible switching device, and includes a plurality of extensions, office lines, and maintenance in addition to the internal control unit and the time switch. Here, a wireless base station (not shown) of the wireless device 21 is connected to the extension of the main device 20 for mobile terminals.

  Each of the plurality of wireless devices 21 forms a wireless area, and is connected to the mobile terminal 30 existing in the wireless area via a wireless line. A private branch exchange is connected to the office line of the main device 20 for portable terminals. The portable terminal 30 is carried by a medical worker, and is used for making a response call with the nurse call handset 1. In addition, a plurality of portable terminals 30 exist in the hospital, and it is possible to identify a medical worker who carries them.

  The pulse sensor 40 is carried by a medical worker in the same manner as the portable terminal 30 and measures the pulse rate per unit time (for example, 1 minute) of the carrying medical worker. Here, the pulse sensor 40 is shaped like a wristwatch, and measures the pulse of the medical worker by being attached to the arm of the medical worker. The pulse sensor 40 includes a pulse information transmission unit (not shown) that transmits pulse information indicating the number of pulses per unit time of the medical staff to the portable terminal 30.

  The nurse call slave unit 1 includes a slave unit control unit (corresponding to a call signal generation unit in claims) 2, a call operation unit 3, a slave unit interface 4, and a slave unit transmission unit 5. ing. The subunit | mobile_unit control part 3 controls each component of the nurse call subunit | mobile_unit 1 so that it may mention later. The call operation unit 3 is operated when a patient calls a medical worker, and generally has a button shape. When the slave unit operation unit 3 is operated, the slave unit control unit 2 generates a calling signal.

  The slave unit interface 4 is for connecting the nurse call slave unit 1 and the nurse call master unit 10 to communicate with each other. The slave unit transmission unit 5 transmits the call signal generated by the slave unit control unit 2 to the nurse call master unit 10 via the slave unit interface 4. Here, the nurse call handset 1 includes a recovery button (not shown) for responding when the patient is called, a microphone and a speaker (not shown) used when the patient has a conversation with the nurse, and the like.

  The nurse call parent device 10 includes a parent device control unit 11, a parent device interface 12, a parent device reception unit 13, a storage unit 14, and a parent device transmission unit 15. The base unit controller 11 controls each component of the nurse call base unit 10 as described later. The master unit interface 12 connects the nurse call master unit 10 and the nurse call slave unit 1 to communicate with each other. The base unit interface 12 connects the nurse call base unit 10 and the mobile terminal main unit 20 to communicate with each other.

  The base unit receiving unit 13 receives the call signal transmitted from the nurse call slave unit 1 via the base unit interface 12. The base unit control unit 11 analyzes the call signal received by the base unit reception unit 13 and identifies the nurse call slave unit 1 that has made the call. Here, the technology for specifying the nurse call slave device 1 that has been called by the parent device control unit 11 is performed using a known technology. In addition, when a voice call is performed between the nurse call slave unit 1 and the nurse call master unit 10 or when a voice call is performed between the nurse call slave unit 1 and the portable terminal 30, The machine receiving unit 13 receives an audio signal transmitted from the nurse call slave unit 1 and an audio signal transmitted from the portable terminal 30. Further, the base unit receiving unit 13 receives pulse information described later from the portable terminal 30.

  The storage unit 14 stores a call table for the nurse call system according to the present embodiment. This call table includes patient identification information for identifying a patient such as a patient name and medical worker identification information for identifying a plurality of medical workers in charge of the patient (for example, names of medical workers). Are associated with each other. Here, the calling table ranks a plurality of medical workers in charge of patients in order from the highest priority (see FIG. 2A). Further, the call table associates with each medical worker an upper limit value of the pulse rate per unit time that the medical worker is considered to be not in a normal state.

  Here, since the nurse call slave device 1 that has called the call specifies the parent device control unit 11, the identification information of the patient such as the patient name is specified based on the bed number in which the nurse call slave device 1 is installed. . In this way, the name of the patient who has called is specified by the call signal received by the base unit receiving unit 13. Moreover, the order of calling the medical worker in charge of the patient and the medical worker, and the upper limit of the pulse rate of the medical worker are specified by the specified patient name.

  As shown in FIG. 2 (a), for example, there are four medical workers A, B, C, and D who are in charge of the patient name “XXX”. The medical worker B has the second calling order, the medical worker C has the third calling order, and the medical worker D has the fourth calling order. Further, the upper limit of the pulse rate of the medical worker A is 80, the upper limit of the pulse rate of the medical worker B is 90, the upper limit of the pulse rate of the medical worker C is 85, and the upper limit of the pulse rate of the medical worker D The value is 80. In addition, in this embodiment, although the upper limit of the pulse rate of each medical worker AD is each set, for example, only one upper limit of the pulse rate is set with respect to each medical worker AD However, it may be used in common for each medical worker A to D.

  The base unit control unit 11 generates an incoming call signal for a portable terminal carried by a medical worker in charge of the patient who has called the call. The base unit transmitter 15 transmits the incoming call signal generated by the base unit controller 11. Here, the incoming call signal includes incoming number information for identifying the mobile terminal to be called. Further, the order in which the base unit control unit 11 generates an incoming call signal or the order in which the base unit transmission unit 15 transmits the incoming call signal is determined according to the call table described above. The base unit control unit 11 generates an incoming call signal with a predetermined interval (for example, 5 seconds). The base unit control unit 11 may have an interval at which the base unit transmission unit 15 transmits an incoming call signal without providing an interval at which the base unit control unit 11 generates the incoming call signal. Here, when the portable terminal 30 responds to the incoming call signal, generation of the incoming call signal is terminated in the parent device control unit 11 or the incoming call signal is transmitted in the parent device transmission unit 15. Exit.

  For example, when a call table as shown in FIG. 2A is used, the base unit control unit 11 first extracts the called number information of the portable terminal 30 carried by the medical worker A and outputs an incoming call signal. Generate. Then, base unit transmitter 15 transmits an incoming call signal. If the medical worker A does not respond at the portable terminal 30 as it is for 5 seconds, the base unit control unit 11 extracts the called number information of the portable terminal 30 carried by the medical worker B and receives the incoming call signal. Is generated. Then, base unit transmitter 15 transmits an incoming call signal. Similarly, when the medical worker B does not respond at the mobile terminal 30 and 5 seconds elapse, the base unit control unit 11 extracts the called number information of the mobile terminal 30 carried by the medical worker C and receives the incoming call. Generate a signal. Then, base unit transmitter 15 transmits an incoming call signal. Further, when the medical worker C does not respond at the portable terminal 30 and 5 seconds elapse, the master unit control unit 11 extracts the called number information of the portable terminal 30 carried by the medical worker D and receives the incoming call signal. Is generated. Then, base unit transmitter 15 transmits an incoming call signal. The main device 20 for portable terminals receives the incoming call signal transmitted from the nurse call parent device 10 and transmits it to the portable terminal 30 via the wireless devices 21 arranged in each wireless area.

  The mobile terminal 30 includes a mobile terminal control unit 31, a mobile terminal reception unit 32, a mobile terminal transmission / reception unit 33, and a notification unit 34. The mobile terminal control unit 31 controls each component of the mobile terminal 30 as described later. The mobile terminal receiving unit 32 receives the pulse information transmitted from the pulse sensor 40. At this time, the mobile terminal control unit 31 adds the identification information of its own mobile terminal 30 to the pulse information received by the mobile terminal receiving unit 32. The mobile terminal transceiver unit 33 receives the incoming call signal transmitted from the wireless device 21, and receives the pulse information received by the mobile terminal receiver unit 32 and added with the identification information by the mobile terminal control unit 31 to the outside. Send.

  Here, when the mobile terminal transceiver unit 33 receives an incoming call signal, the mobile terminal control unit 31 determines whether the incoming call number included in the incoming call signal matches the incoming call number of its own mobile terminal 30 or not. If they match, it is determined that the target of the incoming call signal is its own mobile terminal 30. The notification unit 34 is used to notify a call when the mobile terminal control unit 31 determines that the target of the incoming call signal is its own mobile terminal 30. The notification of the call by the notification unit 34 is a well-known technique, and thus the description thereof is omitted.

  On the other hand, the pulse information transmitted from the portable terminal 30 is received by the wireless device 21. Here, the portable terminal transceiver 33 periodically transmits pulse information. The pulse information received by the wireless device 21 is received by the base unit receiving unit 13 via the mobile terminal main device 20.

  The base unit controller 11 analyzes the pulse information received by the base unit receiver 13 and identifies the portable terminal 30 that has transmitted the pulse information. When the mobile terminal 30 is specified, the parent device control unit 11 specifies a medical worker carrying the mobile terminal 30. Next, the base unit control unit 11 refers to the calling table stored in the storage unit 14 and sets the upper limit value of the pulse rate per unit time of the medical worker specified by the pulse information and the pulse information. Compare the included pulse rate. When the pulse rate included in the pulse information is less than the upper limit value, base unit controller 11 ends the process. On the other hand, when the pulse rate included in the pulse information is equal to or higher than the upper limit value, the parent device control unit 11 changes the order of calling the medical workers set in the call table.

  Specifically, when the pulse rate of the medical worker A carrying the mobile terminal 30 becomes 80 or more, the pulse information includes a numerical value of 80 or more as the pulse rate. 11 determines that the pulse rate of the medical worker A whose calling order is first in the calling table has exceeded the upper limit value, and delays the calling order of the medical worker A fourth (see FIG. 2B). . The base unit control unit 11 generates an incoming call signal according to the call table updated in this way (or the base unit transmission unit 15 transmits the incoming call signal according to the updated call table). Thus, the order of calling the medical staff whose pulse rate is equal to or higher than the upper limit value is delayed.

  As described above in detail, in the present embodiment, the order of calling the portable terminal 30 in response to a call from the nurse call slave device 1 is stored in advance in the storage unit 14 of the nurse call parent device 10, and the portable terminal 30 is The pulse rate of a medical worker to be carried is measured by the pulse sensor 40, and when the number exceeds a predetermined number, the order of calling to the portable terminal 30 is delayed. Thereby, it is possible to preferentially call the mobile terminal 30 carried by a medical worker whose pulse rate is less than the predetermined number. Therefore, it is possible to delay a call to a medical worker who is not in a normal state where the physical condition is bad or the work is concentrated, and the medical worker in a normal state is called preferentially, It is possible to reduce the possibility that a medical staff corresponding to the patient in response to the call will cause a medical accident.

  In the present embodiment, information indicating the order in which the medical workers are called is stored in the storage unit 14, and the nurse call parent device 10 calls the medical workers according to the order. However, the present invention is not limited to this. Not. For example, information indicating a plurality of medical workers to be called may be stored in the storage unit 14, and the nurse call parent device 10 may call all of the medical workers all at once. Here, the base unit controller 11 delays a call to a medical worker whose pulse rate is equal to or greater than a predetermined number.

  Moreover, in this embodiment, although the main | base station control part 11 delays the call with respect to the medical worker whose pulse rate became more than predetermined number, it is not limited to this. For example, the base unit control unit 11 may stop calling a medical worker whose pulse rate is equal to or higher than a predetermined number. As a result, the call is not performed until the pulse rate of the medical worker is less than the predetermined number and the normal state is reached, so the burden on the medical worker can be reduced.

  In the present embodiment, the parent device control unit 11 delays a call to a medical worker whose pulse rate is equal to or higher than a predetermined number. However, the present invention is not limited to this. For example, you may make it delay the timing which operates the alerting | reporting part 34 in the portable terminal 30 which received the incoming call signal. Similarly, the notification unit 34 may not be operated by the mobile terminal 30 that has received the incoming call signal.

  In such a case, the mobile terminal 30 may determine whether to delay the operation of the notification unit 34 without transmitting pulse information from the mobile terminal 30 to the nurse call parent device 10.

  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.

It is a block diagram which shows the structural example of the nurse call system by this embodiment. It is a figure which shows the example of the calling table of the nurse call system by this embodiment.
