Abstract

PROBLEM TO BE SOLVED: To provide a nurse call system configured to be reset to prevent deterioration in working efficiency of a medical worker.SOLUTION: A nurse call extension 1 having a call count equal to or larger than a predetermined value per predetermined time is determined to make a call frequently and have a high possibility of wrong calling, so that the nurse call extension 1 is reset only by operating a response operation portion 16. When a nurse call extension 1 has a call count of less than the predetermined value per predetermined time, the nurse call extension 1 is reset only by the restoration operation of a restoration operation device 5 installed in the vicinity of the nurse call extension 1. Accordingly, the medical worker is required to be near the nurse call extension 1 infrequently, and the nurse call extension 1 is reset without deteriorating the working efficiency of the medical worker.

Description

  The present invention relates to a nurse call system for calling a nurse or a caregiver in response to a request from a patient or a care recipient in a hospital or a care facility.

  Conventionally, in the nurse call system, a nurse call cordless handset installed near a patient or a care recipient (hereinafter collectively referred to as a patient) (for example, near a bed) and a nurse or caregiver (hereinafter collectively). It is connected to the nurse call master unit installed in the staff room where the medical staff is resident (wired or wireless). In the nurse call system configured as described above, when the patient operates the call operation unit provided in the nurse call slave unit, the notification unit provided in the nurse call master unit operates, and the patient selects the medical staff. Can be called. The medical staff can respond by off-hooking the handset provided in the nurse call parent machine, and can talk with the patient.

  In such a nurse call system, it is common to install a corridor lamp between the nurse call slave and the nurse call master. The corridor lamp is attached to the wall surface on the corridor side near the entrance of a room such as a hospital room. The corridor lamp displays patient information such as the number of the attached room and the name of the patient who is hospitalized in the room. The corridor lamp is linked to the nurse call master unit. When the patient calls the nurse call slave unit by operating the call operation unit, the nurse call slave unit calls the nurse call master unit and the corridor lamp. To be notified. At this time, the corridor lamp informs that a call is being made in the hospital room where the corridor lamp is installed by lighting / flashing a lamp provided in the corridor lamp. Thereby, the medical worker etc. in a corridor can identify the hospital room where the patient who performed the call exists.

In addition to the above-described configuration, a portable terminal carried by a medical worker (for example, PHS (Personal
A nurse call system provided with a handy phone system) and a PBX (Private Branch Exchange) is also provided. When a call is made by the nurse call slave, the mobile terminal rings and vibrates to notify. The medical staff can respond by operating the mobile terminal and can make a call with the patient.

  By the way, if the nurse call master unit's handset or portable terminal responds to a call from the nurse call slave unit, the notification by the nurse call master unit or portable terminal stops, and the corridor lamp goes off. There is a nurse call system that is in a state where it can be called again by the nurse call slave (so-called recovery state). However, in such a nurse call system, since a medical worker responds to a call from the nurse call slave by simply answering with the handset or portable terminal of the nurse call parent device, the medical worker stops the patient. In spite of the necessity of going to the hospital room where the patient is present and performing nursing, there is a problem that a medical worker forgets to go to the patient room where the patient is present.

  In order to solve such a problem, a nurse call system in which a restoration button is provided on a corridor lamp and the system is restored by operating the restoration button is known (for example, Patent Document 1). There is also known a nurse call system in which a recovery operation unit is provided in a nurse call slave and the system is restored by operating the recovery operation unit (for example, Patent Document 2). Here, the recovery button and the recovery operation unit have the same function, and hereinafter, these will be collectively referred to as a recovery operation unit.

  In the nurse call system described in Patent Literatures 1 and 2, even though a medical worker responds with the handset or portable terminal of the nurse call parent device, the notification by the nurse call parent device or the portable terminal stops, but the nurse call system Is not restored, and the nurse call system is restored only when the restoration operation unit provided in the vicinity of the corridor lamp or nurse call slave is operated. Therefore, a medical worker who responds with a handset or a portable terminal of a nurse call master unit has to meet both the purpose of operating the recovery operation unit and the purpose of nursing the patient who has called the patient's hospital room. It will be to go to. Therefore, there are fewer cases where the medical staff who answers the call forgets to go to the patient's room.

  By the way, in the nurse call cordless handset, not only the patient operates the call operation unit to call, but the sheet-like mat sensor detects the patient's load, and the infrared sensor detects the movement of the patient's body. There is a nurse call handset that makes a call when it is detected. In addition to these, there are various nurse call slaves that detect and call a patient's condition. However, a nurse call slave that detects a patient's condition and calls it detects not only the patient's condition but also the person's condition other than the patient and makes a call. In some cases, a call was made by mistake. As a result, the nurse call parent device generates an erroneous call notification (hereinafter referred to as a false alarm).

  In addition, the call operation part of the nurse call cordless handset is used for the purpose of the patient talking with the health care worker even when the care worker is not particularly required or when there is no need for the health care worker. Operate and call medical personnel. Although such a call is not a false alarm, it is considered a low priority call compared to a call that requires nursing care.

JP 2003-37679 A JP 2009-77387 A

  As described above, when a call with a nurse call child device that detects the patient's condition or a call with a low priority that is performed by the patient operating the call operation unit frequently occurs, the medical worker operates the recovery operation unit. In order to do this, there is a problem that the work efficiency of the medical staff deteriorates because the patient must frequently go to the patient room. The present invention has been made to solve such a problem, and an object of the present invention is to make it possible to shift to a recovery state so as not to deteriorate the work efficiency of a medical worker.

  In order to solve the above-described problem, in the present invention, when a call is made from the nurse call slave unit in the nurse call master unit, the nurse call slave unit that has made the call does not accept the call. In the nurse call system, when a call from a nurse call cordless handset whose number of calls per predetermined time is equal to or greater than a predetermined value, the nurse call master device responds to the recovery state and other nurse calls. The call from the slave unit is shifted to the recovery state only by the operation of the nurse call slave unit or the recovery operation device installed in the vicinity of the nurse call slave unit.

  According to the present invention configured as described above, the nurse call handset whose number of calls per predetermined time is equal to or greater than a predetermined value is determined to be calling frequently. And the nurse call cordless handset that detects the state of a person other than the patient and makes a call, or detects the slight change in the environment and makes the call, determines that the call is frequently made, It is determined that there is a high possibility of making a call by mistake, and the system is shifted to a recovery state only by performing a response operation at the nurse call parent device. Also, nurse call cordless handsets that make low-priority calls that do not require medical staff's care or that are not particularly used by medical staff are judged to be calling frequently. The system is shifted to the recovery state simply by performing a response operation on the nurse call master unit. On the other hand, for calls from other nurse call slave units, the system is shifted to the recovery state only by the operation of the nurse call slave unit or the recovery operation device installed in the vicinity of the nurse call slave unit. As a result, the frequency of medical workers visiting the nurse call cordless handset or in the vicinity of the nurse call cordless handset is reduced, so that the nurse call system can be shifted to a recovery state without deteriorating the work efficiency of the health care worker. .

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

  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. As shown in FIG. 1, the nurse call system according to the present embodiment is installed in the vicinity of a bed of a patient room where a patient is present, and in the vicinity of a nurse call slave 1 for a patient to perform a call operation and a nurse call slave. The recovery operation device 5 is installed, and a nurse call parent device 10 is installed in a staff room (for example, a nurse station) where a medical worker is resident to notify a call.

  Here, since the nurse call cordless handset 1 is used by each patient, it is installed in the vicinity of each bed. The nurse call handset 1 includes a handset control unit 2, a call operation unit 3, and a handset interface 4. The nurse call parent device 10 includes a control unit 11, an interface 12, a notification unit 13, a timer 14, a count unit 15, a response operation unit 16, and a determination unit 17. Further, a corridor lamp (not shown) is installed between the nurse call slave unit 1 and the nurse call master unit 10.

  Here, the corridor lamp is attached to the wall surface on the corridor side near the entrance of a room such as a hospital room. The corridor lamp displays patient information such as the number of the attached room and the name of the patient who is hospitalized in the room. Moreover, the corridor lamp is interlocked with the nurse call master unit 10, and when the patient makes a call by operating the call operation unit 3 of the nurse call slave unit 1, the nurse call slave unit 1 calls the corridor lamp. Notice. At this time, the corridor lamp informs that a call is being made in the hospital room where the corridor lamp is installed by lighting / flashing a lamp provided in the corridor lamp. Thereby, the medical worker etc. in a corridor can identify the hospital room where the patient who performed the call exists.

  First, the components of the nurse call handset 1 will be described. The subunit | mobile_unit control part 2 is for controlling each component of the nurse call subunit | mobile_unit 1 so that it may mention later, and is comprised by CPU (Central Processing Unit) etc. The call operation unit 3 is for operation when a patient calls a medical worker, and includes a button and the like. Moreover, the subunit | mobile_unit interface 4 is connected to the interface 12 of the nurse call main unit 10 via the corridor lamp, and electrically connects the nurse call sub unit 1 and the nurse call main unit 10. Further, the slave unit interface 3 is connected to the recovery operation device 5.

  In addition, in this embodiment, the nurse call cordless handset 1 is provided with the call operation part 3, and calls it by a patient's intention, but it is not limited to this. For example, the nurse call handset 1 may be configured to include a detection unit that detects the state of the patient. In this case, the nurse call handset 1 makes a call when the detection unit detects a predetermined state of the patient.

  When the patient wants to call a medical staff, the patient operates the call operation unit 3. Then, the subunit | mobile_unit control part 2 produces | generates a calling signal. Here, the call signal includes slave unit identification information for identifying the nurse call slave unit 1 from other nurse call slave units 1. In addition, information such as a bed number is used as the slave unit identification information. Further, the slave unit interface 4 outputs the calling signal generated by the slave unit control unit 2 to the recovery operation device 5 and the nurse call master unit 10. Further, the slave unit interface 4 inputs a recovery signal described later from the recovery operation device 5. When a call can be made between the nurse call slave unit 1 and the nurse call master unit 10, the slave unit interface 4 transmits an audio signal to the nurse call master unit 10, and the nurse call master unit 10 receives a voice signal. Receive a signal. In addition, communication between the nurse call slave device 1, the recovery operation device 5, and the nurse call master device 10 is performed by wire or wirelessly.

  In the nurse call handset 1, when the call operation unit 3 is operated and the handset control unit 2 generates a call signal, the handset control unit 2 does not generate the call signal even if the call operation unit 3 is operated again. It becomes a state. As described above, when a call is made by the nurse call handset 1, the nurse call handset 1 cannot enter the next call (in other words, does not accept the operation of the call operation unit 3). When the handset interface 4 inputs a recovery signal for returning this state to the state before the call, the nurse call handset 1 enters a recovery state in which the next call can be performed again.

  The recovery operation device 5 is connected to the child device interface 4 of the nurse call slave device 1 and electrically connects the recovery operation device 5 and the nurse call slave device 1. Further, the recovery operation device 5 is installed by the nurse call slave unit 1 when the nurse call slave unit 1 is called and the nurse call slave unit 1 cannot make the next call. It is operated by medical personnel who rushed to the hospital room. When the recovery operation device 5 is operated in a state where the call operation unit 3 of the nurse call slave device 1 to which the recovery operation device 5 is connected is operated, the recovery operation device 5 generates a recovery signal to generate the nurse call child. Output to the machine 1 and the nurse call parent machine 10.

  In the present embodiment, the recovery operation device 5 is connected only to the nurse call slave device 1, but may be connected to the interface 12 of the nurse call master device 10. In this case, the recovery operation device 5 is also used to stop the notification operation by the nurse call parent device 10.

  Next, components of the nurse call parent device 10 will be described. The control unit 11 is for controlling each component of the nurse call parent device 10 as will be described later, and includes a CPU or the like. The interface 12 electrically connects the nurse call parent device 10 and the nurse call child device 1 via a corridor lamp. The interface 12 inputs the call signal output from the nurse call handset 1 via the corridor lamp, and outputs a restoration signal generated by the control unit 11. Further, when a call can be made between the nurse call master unit 10 and the nurse call slave unit 1, the interface 12 transmits an audio signal to the nurse call slave unit 1, and receives the audio signal from the nurse call slave unit 1. Receive. Communication between the nurse call parent device 10 and the recovery operation device 5 and the nurse call child device 1 is performed by wire or wireless.

  The notification unit 13 includes at least one device such as a sound output device such as a speaker, a display device such as a display, and a lighting device such as a lamp. Here, when the interface 12 receives a call signal from the nurse call slave unit 1, the control unit 11 operates the notification unit 13. At this time, the control unit 11 outputs a notification sound from the speaker so that the nurse call handset 1 that has been called can be identified based on the handset identification information included in the input call signal. The display display displays that the call is being made and the patient identification information of the patient who made the call, or blinks the lamp.

  The timer 14 is for measuring time. The counting unit 15 is for counting the number of times that the interface 12 has input a call signal from the nurse call slave unit 1 until the time measured by the timer 14 reaches a predetermined time. Here, the control unit 11 operates the timer 14 at a predetermined timing. The predetermined timing is when the operation of the nurse call system starts, and the predetermined time is, for example, 12 hours. The number of times the interface 12 has input a call signal from the nurse call slave unit 1 is counted by the counting unit 15 for each nurse call slave unit 1 using the slave unit identification information included in the call signal.

  For example, when the operation of the nurse call system starts, the control unit 11 operates the timer 14 and the timer 14 starts measuring time. In this state, the count unit 15 counts the number of times the interface 12 has input a call signal including the same slave unit identification information until a predetermined time (for example, 12 hours) elapses. Then, when a predetermined time has elapsed, the control unit 11 resets the timer 14, and the timer 14 starts measuring time again.

  The response operation unit 16 is used for the medical staff to respond to the notification when the notification unit 13 is reporting. Here, the response operation unit 16 is configured by a hook switch or the like installed on a handset stand. When the handset is off-hooked, the response operation unit 16 generates and outputs a response signal. The control unit 11 that has input the response signal stops the operation of the notification unit 13.

  The determination unit 17 is configured by a CPU or the like, and determines whether or not the number of times counted by the count unit 15 is a predetermined value or more. When the interface 12 receives a call signal, the control unit 11 operates the notification unit 13. When the determination unit 17 determines that the number of times counted by the counting unit 15 is equal to or greater than a predetermined value, the control unit 11 only stops the operation of the notification unit 13 when the response operation unit 16 is operated. Instead, the slave unit identification information included in the paging signal input by the interface 12 is extracted, and a recovery signal including the slave unit identification information is generated. The control unit 11 outputs the restoration signal generated by the interface 12 to each nurse call slave unit 1.

  On the other hand, when the response operation unit 16 is operated when the determination unit 17 determines that the number of times counted by the count unit 15 is not equal to or greater than a predetermined value, the control unit 11 stops the operation of the notification unit 13, Does not generate a recovery signal. Here, the predetermined value is a value indicating that the frequency that each nurse call handset 1 calls is high, and is set to about 10 times, for example. That is, in this embodiment, when 10 calls are made during 12 hours measured by the timer 15, it is interpreted that the nurse call handset 1 is called frequently.

  In the nurse call handset 1 that has input this recovery signal through the handset interface 4, the handset determines whether the handset identification information included in the recovery signal matches the handset identification information of its own nurse call handset 1. If it is determined by the control unit 2 and it is determined that they match, the nurse call handset 1 can make the next call again. On the other hand, if it is determined that they do not match, the nurse call handset 1 continues in a state where the next call cannot be made.

  As described above, when the call is frequently performed in the nurse call slave unit 1, the nurse call slave unit 1 is in the restored state only by performing a response operation in the response operation unit 16 of the nurse call master unit 10. Become. In addition, if the call is not frequently performed in the nurse call slave unit 1, even if the response operation unit 16 of the nurse call master unit 10 performs a response operation, the operation of the notification unit 13 only stops. Unless the recovery operation device 5 installed in the vicinity of the nurse call child device 1 is operated, the nurse call child device 1 will not be in the recovery state.

  As described in detail above, according to the present embodiment, when the call operation unit 3 is operated by the nurse call slave unit 1 and the notification unit 13 notifies the nurse call base unit 10, the call operation unit 3 In the nurse call system in which 3 does not accept an operation, for the call from the nurse call handset 1 whose number of calls per predetermined time is equal to or greater than a predetermined value, the notification unit 13 is stopped by a response operation by the response operation unit 16 In addition, the nurse call slave unit 1 is shifted to the recovery state, and a call from the nurse call slave unit 1 whose number of calls per predetermined time is not equal to or greater than a predetermined value is notified by a response operation by the response operation unit 16. The nurse call cordless handset 1 is not moved to the recovery state only by stopping the section 13, and the nurse call Only the recovery operations of the recovery operation device 5 installed in the vicinity of the mobile device 1, so that to migrate the nurse call handset 1 to the recovery state.

  As a result, the nurse call handset 1 whose number of calls per predetermined time is equal to or greater than a predetermined value determines that calls are frequently made. Then, it is determined that the nurse call cordless handset 1 that detects the state of a person other than the patient and makes a call, or detects a slight change in the environment and makes a call, frequently makes a call, It is determined that there is a high possibility that a call has been made by mistake, and the nurse call slave unit 1 is shifted to the recovery state only by operating the response operation unit 16 on the nurse call master unit 10. In addition, it is determined that the nurse call cordless handset 1 that makes a low-priority call that does not particularly require the care of a health care worker or that is not particularly used by the health care worker frequently makes a call. Then, just by operating the response operation unit 16 on the nurse call parent device 10, the nurse call child device 1 is shifted to the recovery state. On the other hand, the nurse call handset 1 in which the number of calls per predetermined time does not exceed the predetermined value can be obtained only by the recovery operation of the recovery operation device 5 installed in the vicinity of the nurse call handset 1. Transition to the recovery state. Therefore, since the frequency at which the medical staff goes to the vicinity of the nurse call cordless handset 1 decreases, the nurse call handset 1 can be shifted to the recovery state without deteriorating the work efficiency of the medical staff.

  In addition, in embodiment mentioned above, although the recovery operation apparatus 5 is installed in the vicinity of the nurse call subunit | mobile_unit 1, it is not limited to this. For example, the recovery operation device 5 may be installed in the nurse call slave device 1.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
