Abstract

PROBLEM TO BE SOLVED: To improve a nurse call system, in which a normal call is given when pressure for depressing a call button is within a range of thresholds and an emergency call is given when the pressure is outside a range of the thresholds, such that thresholds can be set as properly as possible when the thresholds are set by investigating distribution of pressures for each patient and setting a threshold for each patient based on the distribution.SOLUTION: A pressure sensor 4 is provided on a nurse call terminal 1 for detecting pressure to depress a call button 3. If a current date when the call button 3 is depressed is in within a predetermined period for investigating distribution of pressure values and is included in a certain period before and after scheduled surgery, the pressure value is not obtained. If the current date is not included in the certain period, the pressure value is obtained to set the range of the obtained pressure values as a range of thresholds. Then, extremely small pressure values are not included in the investigation of the distribution and therefor, it can be done that if a pressure value to depress the call button 3 is within the range of the thresholds, a normal call is made and if the value is outside the range of thresholds, an emergency call is made.

Description

  The present invention relates to a nurse call system for calling a nurse in response to a request from a patient in a hospital or the like.

  Conventionally, a nurse call system is a nurse call station installed near a patient (eg, in the vicinity of a bed, etc.) and a nurse station where nurses and nurses (hereinafter referred to as medical workers) reside. The call base unit is connected by wire 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. At this time, the medical worker can answer the call by off-hooking the handset provided in the nurse call master unit and can make a call 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 to the call by operating the mobile terminal and can make a call with the patient.

  By the way, when a patient calls a medical worker, the requirements vary. In addition, there are cases where there are urgent cases depending on the requirements, and there are cases where it is desirable to immediately contact medical personnel. For this reason, a technique is known in which a call button and an emergency call button are provided on a nurse call slave, and the operation of the nurse call parent differs depending on the operated button (see, for example, Patent Document 1). However, the technique described in Patent Document 1 has a problem that the installation area becomes large because it is necessary to provide two buttons, a call button and an emergency call button, in the nurse call cordless handset. In addition, if the patient does not understand the purpose of the call button and emergency call button, or if the type of button cannot be distinguished in the case of hemorrhoids, there is a problem that an incorrect call is made. .

  In particular, when a patient operates an emergency call button, the patient's state is often not a normal state, and thus the emergency call button cannot be clearly grasped and operated. Therefore, a technique is known in which the pressure at which the call button is pressed is detected by a pressure sensor, and the display on the display device is made different depending on the detected pressure (see, for example, Patent Document 2). Thereby, one call button can be used as a plurality of call buttons.

  However, in the technique described in Patent Document 2, since the pressure for pressing the call button varies among individuals, even in the same situation, the pressure for pressing the call button differs depending on the patient. There is a problem that it becomes impossible to properly distinguish.

  In order to solve such a problem, it is conceivable to examine the distribution of pressure values at which the call button is pressed for each patient, and to set the upper limit value and the lower limit value as threshold values, and to change the threshold values for each patient. However, when examining such a distribution, adding a case where the call button is pressed while the patient is weak, the pressure becomes extremely small, and an appropriate threshold cannot be obtained. was there.

JP 2000-224321 A JP 2005-233772 A

  The present invention has been made to solve the above-described problems. When the pressure at which the call button is pressed is within the threshold value range, the nurse call master device performs normal notification, and the threshold value is set. When the call is pressed, the nurse call system that gives an emergency notification to the nurse call master unit examines the distribution of the pressure value at which the call button is pressed for each patient, and based on this distribution, sets the threshold value for each patient. It is an object of the present invention to be able to set an appropriate threshold as much as possible when setting.

  In order to solve the above-described problems, in the present invention, a pressure sensor that detects the pressure at which the call button is pressed is provided in the nurse call slave unit, and the current date and time when the call button is pressed is the pressure detected by the pressure sensor. The pressure at which the call button was pressed if it was determined that the current date / time is included in a certain period before and after the scheduled surgery if it falls within a predetermined period for examining the distribution of values. The value of the pressure at which the call button was pressed when it is determined that the value is not included is acquired, and the range of the pressure value obtained by this distribution or the range of the value of this pressure A range obtained by adding a predetermined value before and after is set as the threshold range. When the call button is pressed, if the pressure value is within the threshold range, the nurse call master unit performs normal notification, and if the pressure value is outside the threshold range, the nurse call parent is notified. An emergency notification is made on the machine.

  According to the present invention configured as described above, when the pressure value at which the call button is pressed is within the threshold range, the nurse call master device performs normal notification, and when it is outside the threshold range In the nurse call system that performs emergency notification on the nurse call master unit, the distribution of the pressure value at which the call button is pressed is examined for each patient, and the call button is used when setting the threshold value for each patient based on this distribution. If the current date and time when is pressed is included in a certain period before and after the scheduled surgery, it is not included in the distribution, so exclude the case where the pressure to press the call button becomes extremely low Can do. Thereby, it is possible to set an appropriate threshold as much as possible.

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 a setting of the range of the threshold value 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 in a hospital room where a patient is present, and a nurse call cordless handset 1 for a patient to perform a call operation and a nurse in which a medical worker is resident And a nurse call parent device 10 which is installed in a station and notifies a call.

  Here, the nurse call handset 1 includes a handset controller 2, a call button 3, a pressure sensor 4, and a handset interface 5. In addition, the nurse call master unit 10 includes a control unit 11, an interface 12, a notification unit 13, a response operation unit 14, a calendar unit 15, a surgery schedule acquisition unit 16, a period setting unit 17, a period determination unit 18, and a surgery schedule determination unit 19. The range setting unit 20 is provided. Further, a corridor lamp (not shown) is installed between the nurse call slave unit 1 and the nurse call master unit 10.

  The corridor lamp is attached to the wall surface on the corridor side near the entrance of the 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 slave unit 1 and the nurse call master unit 10, and when the patient calls the call button 3 of the nurse call slave unit 1, the nurse call slave unit 1 Notify the corridor to the call. 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 built-in lamp or the like. Thereby, the medical worker etc. who are in a corridor can identify the hospital room where the calling patient and the medical worker are.

  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 button 3 is used when the patient calls a medical worker. Here, the call button 3 is provided in a portable housing so that it can be used by the patient. The casing is provided with a cord, and a plug is provided at the tip of the cord. This plug is connected to an outlet provided in a wall unit installed on the wall surface near the bed. Therefore, the casing of the nurse call slave 1 can be moved in the vicinity of the bed.

  In the present embodiment, the casing of the nurse call slave unit 1 is connected to the wall unit by a cord, but is not limited to this. For example, the nurse call handset 1 may be wireless.

  The pressure sensor 4 is composed of a well-known sensor and detects a force with which the call button 3 is pressed. Further, the pressure sensor 4 outputs the detected pressure value to the slave unit control unit 2. The slave unit interface 5 is connected to the interface 12 of the nurse call master unit 10, and electrically connects the nurse call slave unit 1 and the nurse call master unit 10.

  When the call button 3 is pressed, the pressure sensor 4 detects the force by which the call button 3 is pressed, and outputs the detected pressure value to the handset controller 2. The subunit | mobile_unit control part 2 produces | generates the calling signal containing the value of the input pressure, and outputs it to the nurse call parent | base_unit 10 by the subunit | mobile_unit interface 5. FIG. Here, the call signal includes slave unit identification information for identifying the nurse call slave unit 1 from other nurse call slave units 1.

  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 storage device such as a CPU or a memory as a main component. Here, the surgery schedule acquisition unit 16, the period setting unit 17, the period determination unit 18, the surgery schedule determination unit 19, and the range setting unit 20, which will be described later, are also configured by a CPU, a memory, and the like, similar to the control unit 11.

  The interface 12 is connected to the slave unit interface 5 of the nurse call slave unit 1 and electrically connects the nurse call master unit 10 and the nurse call slave unit 1. Here, communication between the nurse call parent device 10 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. Moreover, the alerting | reporting part 13 alert | reports that the patient is calling the medical worker. Here, when the interface 12 receives a call signal from the nurse call slave device 1, the parent device control unit 11 operates the notification unit 13. At this time, the base unit 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. Or the display display shows that the call is being made, the name of the patient who made the call, etc., and the lamp blinks.

  Moreover, the alerting | reporting part 13 changes alerting | reporting according to the force by which the call button 3 was pressed down. That is, the alerting | reporting part 13 alert | reports in an emergency state that the patient is calling the medical worker urgently while alert | reporting that the patient is calling the medical worker in a normal state.

  The response operation unit 14 includes a handset, a pedestal, a hook switch, and the like. When the handset constituting the response operation unit 14 is picked up from the pedestal, the hook switch operates to be off-hook, and the handset is returned to the pedestal. As a result, the hook switch operates and goes on-hook.

  The calendar unit 15 is for acquiring current date and time information, and includes a clock or the like. Thereby, the control unit 11 can acquire the current date and time information from the calendar unit 15. The calendar unit 15 may be provided outside the nurse call parent device 10.

  The surgery schedule acquisition unit 16 acquires patient information including surgery schedule information indicating the date and time when the patient is scheduled to undergo surgery from a server or the like installed outside the nurse call parent machine 10. Here, the surgery schedule information includes patient identification information for identifying the patient from other patients.

  The period setting unit 17 is for setting period information indicating a predetermined period for examining the distribution of pressure values, and the predetermined period may be set manually or automatically. Anyway. In the present embodiment, the predetermined period is three days from the time when the patient is hospitalized. Since this predetermined period is a period for examining the distribution of how much force the patient presses the call button in a normal state, this period may be a fixed length or the patient's hospitalization period It may be lengthened or shortened according to the length of.

  The period determination unit 18 determines whether or not the current date and time information acquired from the calendar unit 15 by the control unit 11 corresponds to a predetermined period set by the period setting unit 17. Here, when the interface 12 receives a call signal, the control unit 11 operates the period determination unit 18.

  The operation schedule determination unit 19 determines whether or not the current date and time information acquired by the control unit 11 from the calendar unit 15 is included in a certain period before and after the operation schedule information acquired by the operation schedule acquisition unit 16. Here, when the interface 12 inputs a call signal and the period determination unit 18 determines that the current date and time information acquired from the calendar unit 15 corresponds to the predetermined period set by the period setting unit 17, the control unit 11. Operates the operation schedule determination unit 19. In addition, the certain period is a period in which the patient is in a state different from the normal state due to the influence of the operation, and in this embodiment, the period from two hours before the operation start time to four hours after the operation start time. Point to. In addition, you may make it vary this fixed period according to the content of surgery, etc.

  The range setting unit 20 determines whether or not the current date and time is included in a certain period before and after the operation schedule when the interface 12 inputs the calling signal within the predetermined period described above, and is included in the calling signal. Set whether or not to use the pressure value. Here, the range setting unit 20 examines the distribution for each nurse call handset 1 based on the handset identification information included in the call signal, and sets the range of pressure values.

  When the interface 12 receives a call signal, the period determination unit 18 determines whether the current date and time information acquired by the control unit 11 from the calendar unit 15 corresponds to the predetermined period set by the period setting unit 17. To do. When the period determination unit 18 determines that the current date / time information corresponds to a predetermined period, the surgery schedule determination unit 19 determines that the acquired current date / time information is constant before and after the surgery schedule information acquired by the surgery schedule acquisition unit 16. It is determined whether it is included in the period. When the operation schedule determination unit 19 determines that the current date and time information is included in a certain period before and after the surgery schedule information, the range setting unit 20 sets the pressure value included in the call signal input by the interface 12. Is not adopted.

  On the other hand, when the operation schedule determination unit 19 determines that the current date and time information is not included in a certain period before and after the operation schedule information, the range setting unit 20 sets the pressure included in the call signal input by the interface 12. Adopt value.

  In addition, during the predetermined period described above, when the interface 12 inputs a call signal, the control unit 11 causes the notification unit 13 to operate in a normal state. The reason why the notification unit 13 performs notification in a normal state in a predetermined period is that the predetermined period corresponds to a period in which the distribution of the pressure value when the patient presses the call button 3 is examined. This is because the range is not fixed.

For example, as shown in FIG. 2, if a patient is admitted at “10:30 on June 7, 2012”, it is three days after being admitted to the period setting unit 17. “10:30” is set as the predetermined period. When the call button 3 is pressed in this state, the pressure sensor 4 detects a pressure value of “120 g”. The subunit | mobile_unit control part 2 produces | generates the calling signal containing the pressure value "120g" and subunit | mobile_unit identification information, and outputs it to the nurse call main unit 10 by the subunit | mobile_unit interface 5. FIG. Here, g (gram) is used as the unit of the pressure value, and 100 g corresponds to 0.98N.

  When the interface 12 of the nurse call parent device 10 receives a call signal, the control unit 11 identifies the nurse call child device 1 that has called by the child device identification information included in the call signal, and the range setting unit 20 distributes the distribution. Let me check. The period determination unit 18 acquires “11:16 on June 7, 2012” that is the current date and time information from the calendar unit 15, and this current date and time information is a predetermined period “2012” set by the period setting unit 17. It is determined whether it corresponds to “June 7th 10:30” to “2012 June 10th 10:30”. In this case, the period determination unit 18 determines that the current date information corresponds to a predetermined period.

  Then, the operation schedule determination unit 19 sets a constant value before and after the above-mentioned current date / time information “June 7, 2012 11:16”, which is the operation schedule information “June 9, 2012 10:00”. It is determined whether it is included in the period of “June 9, 2012, 8:00” to “June 9, 2012, 14:00”. In this case, the operation schedule determination unit 19 determines that the current date and time information is not included in the certain period. Accordingly, the range setting unit 20 employs a pressure value of “120 g”.

  Similarly, the current date and time information is “50 g”, which is the pressure value pressed at “June 7, 2012 13:27”, and the current date and time information is pressed at “June 7, 2012 17:08”. The pressure value “160 g”, the current date / time information “80 g”, the pressure value pressed at “14:15 on June 8, 2012”, and the current date / time information “June 8, 2012” “110 g” which is the pressure value pressed at “22:32 on the day”, and “60 g” which is the pressure value pressed at “18:22 on June 9, 2012” as the current date and time information are set in the range. Adopted by the unit 20.

  On the other hand, since the current date and time information is “25 g”, which is the pressure value pressed on “June 9, 2012 12:15”, is included in the above-described fixed period, the range setting unit 20 does not employ it. Therefore, the range setting unit 20 sets “40 g”, which is a lower limit value of the pressure at which the call button 3 is actually pressed down, to “10 g”, which is a predetermined value, as the lower limit value of the threshold value. Further, the range setting unit 20 sets “170 g”, which is the upper limit value of the pressure at which the call button 3 is actually pressed down, to a predetermined value “10 g”, and sets “170 g” as the upper limit value of the threshold value.

  That is, the range setting unit 20 sets “40 g” to “170 g” as the threshold range. When the patient presses the call button 3 after the predetermined period ends, the control unit 11 of the nurse call parent device 10 refers to the range setting unit 20 and the pressure included in the call signal input by the interface 12. When the value of is within the threshold range, the notification unit 13 is operated in a normal state. On the other hand, when the pressure value included in the paging signal input by the interface 12 is outside the threshold range, the notification unit 13 is operated in an emergency state.

  As described above in detail, according to the present embodiment, the nurse call handset 1 is provided with the pressure sensor 4 for detecting the pressure at which the call button 3 is pressed, and the current date and time when the call button 3 is pressed is determined by the pressure sensor. If the current date and time is included in a certain period before and after the scheduled surgery, and if it is determined that it is included The value of the pressure at which the button was pressed is not acquired, and if it is determined that it is not included, the value of the pressure at which the call button was pressed is acquired, and a predetermined value is added before and after the obtained pressure value range. The range setting unit 20 sets the selected range as the threshold range. When the call button 3 is pressed after a predetermined period of time has elapsed, if the pressure value is within the threshold range, the nurse call master unit 10 performs normal notification, and the pressure value is the threshold value. When it is out of the range, an emergency notification is made by the nurse call master unit 10.

  As a result, when the pressure value at which the call button 3 is pressed is within the threshold range, the nurse call master unit 10 performs normal notification, and when it is outside the threshold range, the nurse call base unit 10 In the nurse call system that performs emergency notification, the distribution of the pressure value at which the call button 3 is pressed is checked for each patient, and the call button 3 is pressed when setting the threshold value for each patient based on this distribution. When the current date and time is included in a certain period before and after the scheduled surgery, the value is not adopted, so that the case where the pressure to press the call button 3 becomes extremely low can be excluded. . Thereby, it is possible to set an appropriate threshold as much as possible.

  In the above-described embodiment, a range obtained by adding a predetermined value to the lower limit value and the upper limit value of the pressure value acquired by the range setting unit 20 within a predetermined period is set as the threshold value range, but is not limited thereto. For example, the lower limit value and the upper limit value of the pressure value acquired by the range setting unit 20 within a predetermined period may be set as the threshold range.

  In the above-described embodiment, the range setting unit 20 excludes a certain period before and after the scheduled surgery from the predetermined period for examining the distribution, but the present invention is not limited to this. For example, in addition to surgery, a certain period of time before and after the scheduled time when the patient presses the call button 3 may become extremely large or small may be excluded from a predetermined period for examining the distribution. good. Specifically, an infusion scheduled period or a sleep scheduled period may be applied.

  In the above-described embodiment, the notification unit 13 does not perform emergency notification until a predetermined period elapses, but is not limited thereto. For example, a predetermined provisional value may be set as the threshold range, and this provisional location may be used as the threshold range until a predetermined interval elapses.

  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.
