Abstract

<P>PROBLEM TO BE SOLVED: To call a nurse call master unit only when abnormality occurs in a patient or medical equipment as much as possible. <P>SOLUTION: A control part 21 for an adapter generates a calling signal and outputs it to a nurse call slave unit 31 only in the case that a detection part 23 continuously detects contact signals outputted from the medical equipment 10 until a timer part 24 finishes measuring the preset time. In a nurse call system to which it is inputted, reporting is performed. Thus, since reporting is not performed when the contact signal is temporarily outputted from the medical equipment 10, the possibility of calling the nurse call master unit 32 is increased only when abnormality occurs in a patient or the medical equipment 10. Thus, a medical worker is not called vainly and the job efficiency of the medical worker is improved. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a nurse call link adapter for linking a medical device such as a ventilator used in a hospital or the like with a nurse call system for calling a medical worker such as a doctor or a nurse.

  Conventionally, when a patient cannot breathe by himself / herself, a medical device such as a ventilator (hereinafter simply referred to as a medical device) has been used. In addition, medical workers constantly monitor patients who are using medical devices. In addition, if an abnormality occurs due to the patient's breathing stoppage, or an abnormality occurs due to a drop in the equipment attached to the patient or a malfunction of the medical device, the medical device may Notify that an abnormality has occurred in the medical device. A medical worker can grasp that an abnormality has occurred in a patient or a medical device by listening to an alarm sound output from the medical device.

  By the way, a busy medical worker may not always be in a hospital room where medical equipment is installed. In such a case, even if the medical device outputs an alarm sound, if the medical device is not near the hospital room where the medical device is installed, the health care worker cannot hear the alarm sound. I could not respond. In addition, when a health care worker on the move enters the range where an alarm sound can be heard, the health care worker can cope with a patient or a medical device. However, when it takes a long time for a health care worker on the move to enter the range where the alarm sound can be heard, the response to the patient or medical device has been delayed.

In this way, medical workers are informed that an abnormality has occurred in a patient or medical device without placing a medical worker in a hospital room where the medical device is installed or relying on a moving medical worker. In order to make a person grasp, a nurse call system interlocked with a medical device is known (for example, refer to Patent Document 1). By using such a nurse call system, an abnormality has occurred in the patient call or medical device in the nurse call parent device installed in a room where a medical worker will always be (for example, a staff room). A call indicating that this is informed, and the room where the call was made is notified. A medical worker who has heard the call can promptly respond to a patient or medical device in which an abnormality has occurred by confirming the room to which the call has been made and rushing to the room. The nurse call system described in Patent Document 1 is a nurse call adapter for connecting a medical device and a nurse call slave unit, a nurse call slave unit installed in a hospital room for calling a medical worker, and a call notification. It has a nurse call parent machine. In addition, this type of medical device not only outputs an alarm sound but also outputs a notification signal when an abnormality occurs in the patient or the medical device. The nurse call adapter to which the medical device is connected inputs an alarm signal from the medical device. The nurse call adapter that has received the alert signal converts the alert signal into a nurse call signal (calling signal output from the nurse call slave) and outputs the converted signal to the nurse call slave. The nurse call slave unit outputs a nurse call signal to the nurse call master unit. The nurse call master device that has received this signal performs the same operation as when the call operation is performed by the nurse call slave device, and notifies the patient or medical device that an abnormality has occurred. Here, the alarm signal is output as a contact signal (electrical signal for controlling the nurse call slave connected to the medical device), and the steady state is the make contact (the switch is opened). If it is, a break contact (in a state where the switch is closed) is outputted, and if the steady state is a break contact, it is outputted as a make contact.

  By the way, a patient to whom a ventilator is attached as a medical device is breathing by forced ventilation using the ventilator. In rare cases, the patient may behave against forced ventilation due to throat soaking. As a result, the patient's exhalation and inhalation from the ventilator may collide (so-called fighting). As a result, the ventilator disturbs the respiratory ventilation volume and the ventilation frequency set in advance in its own device, and outputs a contact signal. In addition, when the patient temporarily throats, the ventilator temporarily outputs a contact signal in order to output a contact signal in accordance with the fighting state. In such a case, the nurse call adapter that temporarily inputs the contact signal converts the contact signal into a call signal and outputs the call signal to the nurse call parent device via the nurse call slave device. As a result, the nurse call master performs notification. Therefore, when a medical worker who has grasped the notification arrives at the hospital room where the ventilator is placed in the fighting state, the operation of the ventilator has returned to normal.

  Therefore, in the nurse call system described in Patent Document 1, even if the medical device outputs a contact signal for a moment, the nurse call parent device performs a notification operation as an abnormality has occurred in the patient or the medical device. For this reason, the health care professional cannot determine whether the notification by the nurse call parent device is due to the occurrence of an abnormality in the patient or medical device or because the patient is temporarily throated. It was. Therefore, even if the notification is due to the patient temporarily throating, there is a problem that the medical staff has to rush to the hospital room where the medical device is installed.

  The present invention has been made to solve such a problem, and an object of the present invention is to call a nurse call parent machine only when an abnormality occurs in a patient or a medical device as much as possible.

  In order to solve the above-described problem, the nurse call link adapter of the present invention continuously detects the signal output from the medical device until the timer unit finishes measuring the preset time. When the determination unit determines, a call signal for calling a medical worker is generated and output to the outside.

  Moreover, according to the other aspect of this invention, the pulse which forms the signal output from the medical device is counted in a count part. A call to call a health care worker when the count number determination unit determines that the number of times counted by the count unit has exceeded a predetermined number of times until the timer unit finishes measuring the preset time. A signal is generated and output to the outside.

  According to the present invention configured as described above, a call signal is generated and output to the outside only when a signal output from a medical device is continuously detected for a predetermined time. Notification is performed. As a result, notification is not performed when a signal is temporarily output from the medical device, so that it is possible to increase the possibility that the nurse call parent device is called only when an abnormality occurs in the patient or the medical device. it can. Therefore, the medical worker is not called unnecessarily, and the business efficiency of the medical worker can be improved.

  Further, according to another aspect of the present invention, a call signal is generated and output to the outside only when the number of detections of pulses forming a signal output from a medical device exceeds a predetermined number. Notification is performed in the nurse call system that inputs. As a result, notification is not performed when a signal is temporarily output from the medical device, so that it is possible to increase the possibility that the nurse call parent device is called only when an abnormality occurs in the patient or the medical device. it can. Therefore, the medical worker is not called unnecessarily, and the business efficiency of the medical worker can be improved.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of a medical device linked nurse call system including a nurse call linked adapter according to the present embodiment. As shown in the figure, the medical device-linked nurse call system includes a medical device 10, a nurse call-linked adapter 20, and a nurse call system 30. The medical device 10 includes a medical device control unit, a medical device determination unit, a medical device output unit, and a medical device notification unit (not shown). The nurse call interlocking adapter 20 includes an adapter control unit (corresponding to a control unit in claims) 21, an adapter interface unit (hereinafter referred to as an adapter I / F unit) 22, a detection unit 23, and a timer. The unit 24 and the determination unit 25 are provided. The nurse call system 30 includes a nurse call slave device 31 and a nurse call parent device 32. The nurse call slave unit 31 includes a slave unit control unit and a call operation unit (not shown). The nurse call parent device 32 includes a parent device control unit and a notification unit (not shown).

  In FIG. 1, a ventilator or the like is applied as the medical device 10. A ventilator forces a patient to breathe. The medical device control unit controls each component of the medical device 10 as described later. The medical device determination unit monitors whether or not the breathing motion by the own device is normally performed. When the medical device determination unit determines that an abnormality has occurred in the patient or the medical device 10, the medical device control unit is connected to the medical device 10 via the contact signal (nurse call interlock adapter 20). An electrical signal for controlling the nurse call slave unit 31 is generated and output. Here, the medical device control unit energizes a relay (not shown) provided inside the medical device 10 in order to output a contact signal. The energized relay closes the open switch and outputs the contact signal generated by the medical device controller. In this embodiment, the energized relay closes the open switch and outputs a contact signal, but is not limited to this. For example, the energized relay may output a contact signal by opening a closed switch. The medical device output unit outputs the contact signal output from the relay to the outside. The medical device notification unit notifies that a patient's breathing motion or an abnormality has occurred in the device itself.

  Here, the medical device control unit generates and outputs a contact signal only while the medical device determination unit determines that an abnormality has occurred in the patient or the medical device 10. In other words, when the medical device determination unit determines that the patient or the medical device 10 in which the abnormality has occurred has returned to the original state, the medical device control unit stops generating the contact signal and outputs the contact signal. To stop. Therefore, the medical device 10 temporarily outputs a contact signal. Therefore, the contact signal temporarily output from the medical device 10 is caused by an abnormality caused by a sudden change in the patient's condition, a device attached to the patient dropping out, or a failure of the medical device 10. It is not output.

  The specific operation of the medical device 10 is as follows. The medical device control unit performs forced ventilation according to a preset respiratory ventilation amount and the number of ventilations for the patient to which the medical device 10 is attached. At this time, the medical device determination unit monitors whether or not the respiratory ventilation volume and the ventilation frequency during operation are in accordance with a preset respiratory ventilation volume and ventilation frequency.

(1) When a patient with a ventilator is violated against forced ventilation, such as being able to throat, and temporarily becomes fighting, the patient with a ventilator is forced to ventilate, such as with a throat When the fighting operation occurs and the fighting state is temporarily entered, the medical device control unit operates the medical device notification unit to confirm that the patient's breathing motion or abnormality has occurred in the patient's own device. Inform. Further, the medical device control unit generates and outputs a contact signal. Then, the medical device output unit outputs the contact signal input from the medical device control unit to the nurse call interlocking adapter 20.

  When the fighting state returns to the original state, the medical device control unit stops the medical device notification unit and ends the notification. Further, the medical device control unit stops generating the contact signal and stops the output. The medical device output unit stops the output of the contact signal to the nurse call interlocking adapter 20 because the input of the contact signal from the medical device control unit stops. In this example, the medical device 10 outputs a contact signal for 3 seconds in the fighting state.

(2) When the patient's condition suddenly changes, an instrument attached to the patient falls off, or an abnormality occurs due to a failure of the medical device 10, the patient's condition changes suddenly, or the instrument attached to the patient When an abnormality occurs due to dropout or a failure of the medical device 10, the medical device control unit operates the medical device notification unit to cause an abnormality in the patient's breathing motion or the device itself. Inform you. Further, the medical device control unit generates and outputs a contact signal. Then, the medical device output unit outputs the contact signal input from the medical device control unit to the nurse call interlocking adapter 20. In this example, the medical device 10 outputs a contact signal continuously for 10 seconds or more.

  The nurse call link adapter 20 is connected to the medical device 10 and the nurse call slave unit 31 via a transmission line, and is interposed between the medical device 10 and the nurse call slave unit 31 to connect them. is there. In addition, the nurse call interlocking adapter 20 inputs the contact signal output from the medical device 10.

  The adapter control unit 21 controls each component of the nurse call link adapter 20 as described later. The adapter I / F unit 22 is connected to the medical device 10 so that the nurse call link adapter 20 communicates with the medical device 10. The adapter I / F unit 22 is connected to the nurse call slave unit 31 so that the nurse call link adapter 20 communicates with the nurse call slave unit 31.

  The detection unit 23 detects a contact signal output from the medical device 10 when an abnormality occurs in the patient or the medical device 10. Specifically, when the medical device 10 and the nurse call link adapter 20 are connected by a transmission line, the detection unit 23 indicates that the contact signal output from the medical device 10 is an adapter I / F unit 22. It is detected that the input to the nurse call interlocking adapter 20 via. The timer unit 24 measures a preset time. The medical staff can set the time for measurement by an adapter setting unit (not shown). Here, the time set by the adapter setting unit is, for example, 10 seconds. Thereby, the timer part 24 measures the time for 10 seconds preset by the setting part for adapters.

  When the detection unit 23 detects the contact signal output from the medical device 10, the adapter control unit 21 operates the timer unit 24, and the timer unit 24 starts measuring time. Further, the adapter control unit 21 is configured such that when the detection unit 23 does not detect the contact signal output from the medical device 10 or when the timer unit 24 measures until a preset time, the timer unit The operation of 24 is stopped.

  The determination unit 25 determines whether or not the detection unit 23 continuously detects the contact signal output from the medical device 10 until the timer unit 24 finishes measuring the preset time. In other words, the determination unit 25 determines whether the detection unit 23 continuously detects the contact signal output from the medical device 10 for 10 seconds. Here, when the detection unit 23 detects the contact signal output from the medical device 10, the adapter control unit 21 operates the determination unit 25, and the determination unit 25 starts processing. Further, the adapter control unit 21 determines the determination unit 23 when the detection unit 23 does not detect the contact signal output from the medical device 10 or when the timer unit 24 measures until a preset time. 25 operation is stopped.

(1) When a patient with a ventilator moves against the forced ventilation, such as being able to throat, and temporarily enters a fighting state, the patient with the ventilator is forced to ventilate, such as with a throat When the operation is reversed, the medical device 10 outputs a contact signal for 3 seconds in the fighting state when the fighting state is temporarily entered. Therefore, the determination unit 25 does not continuously detect the contact signal output from the medical device 10 until the timer unit 24 finishes measuring the preset time, in other words, 10 It is determined that the detection unit 23 no longer detects the contact signal output from the medical device 10 in a state of less than 2 seconds. Then, the adapter control unit 21 determines that the patient or the medical device 10 has temporarily become abnormal (that is, has temporarily become fighting). Therefore, the adapter control unit 21 does not generate a call signal (or does not output the generated call signal).

(2) When the patient's condition suddenly changes, an instrument attached to the patient falls off, or an abnormality occurs due to a failure of the medical device 10, the patient's condition changes suddenly, or the instrument attached to the patient When an abnormality occurs due to the drop or the medical device 10 malfunctioning, the medical device 10 continuously outputs a contact signal for 10 seconds or more. Therefore, the determination unit 25 continuously detects the contact signal output from the medical device 10 until the timer unit 24 finishes measuring the preset time, in other words, the detection unit 23. Determines that the contact signal output from the medical device 10 has been detected for more than 10 seconds. Then, the adapter control unit 21 causes an abnormality in the patient or the medical device 10 (that is, when the patient's condition changes suddenly, an instrument attached to the patient falls off, or the medical device 10 breaks down). It is determined that an abnormality has occurred. Therefore, the adapter control unit 21 generates a call signal (or outputs the generated call signal). Here, when generating the call signal, the adapter control unit 21 may add call type information indicating a call type such as a normal call or an emergency call.

  The nurse call cordless handset 31 is installed in the vicinity of a patient in the patient's room (for example, near the bed), and connects the nurse call interlocking adapter 20 and the nurse call master set 32 via a transmission line. The control unit for handset controls each component of the nurse call handset 31 as described later. The call operation unit is operated so that the patient calls the medical staff. When the call operation unit is operated, the slave unit control unit generates a call signal. When the call signal output from the nurse call link adapter 20 is input, the slave unit control unit adds identification information for identifying the nurse call slave unit 31 to the input call signal. Further, the slave unit control unit outputs a calling signal to the nurse call parent unit 32.

  In addition, although the control part for subunit | mobile_units has added the identification information for identifying the nurse call subunit | mobile_unit 31 when the call signal is input from the nurse call interlocking | linkage adapter 20, it is not limited to this. For example, the slave unit control unit may add not only identification information for identifying the nurse call slave unit 31 but also information indicating that it has been output from the nurse call link adapter 20.

  The nurse call master unit 32 is installed in a room (for example, a staff room) where a medical worker is present, and responds to a call from a patient or notifies a call from a patient. The nurse call parent device 32 is for notifying that an abnormality has occurred in the patient or the medical device 10. Here, a plurality of nurse call slave devices 31 are connected to the nurse call parent device 32. The base unit control unit controls each component of the nurse call base unit 32 as described later. The notification unit notifies the call from the nurse call slave unit 31 and also notifies the patient using the medical device 10 connected to the nurse call interlocking adapter 20 and the occurrence of an abnormality in the medical device 10 itself. Here, the notification unit includes a speaker, a display display, an indicator lamp, and the like. When the nurse call master unit 32 receives the call signal output from the nurse call slave unit 31, the master unit control unit operates the notification unit to output a ringing tone from the speaker or displays the call on the display. Calls are notified by making a call or turning on or blinking the indicator lamp.

  Further, the parent device control unit analyzes the call signal and identifies the nurse call child device 31 that has called from the identification information added to the call signal. If call type information indicating the call type is added to the call signal, the parent device control unit may cause the notification unit to notify the call corresponding to the call type. When information indicating that the call signal is output from the nurse call link adapter 20 is added, the base unit control unit may cause the notification unit to notify the information.

  As described above in detail, in the nurse call link adapter 20 of this embodiment, the detection unit 23 outputs the contact signal output from the medical device 10 until the timer unit 24 finishes measuring the preset time. Only when the detection is continued, the adapter control unit 21 generates a call signal and outputs the call signal to the nurse call slave unit 31. In the nurse call system to which this is input, notification is performed. As a result, when a contact signal is temporarily output from the medical device 10, notification is not performed, so that the nurse call parent device 32 can be called only when an abnormality occurs in the patient or the medical device 10. Sexuality can be increased. Therefore, the medical worker is not called unnecessarily, and the business efficiency of the medical worker can be improved.

  In the above-described embodiment, the nurse call link adapter 20 inputs the contact signal output from the medical device 10, but the present invention is not limited to this. For example, the nurse call link adapter 20 may output an alarm signal that is output from the medical device 10 and indicates that an abnormality has occurred in the patient or the medical device 10.

  Further, in the above-described embodiment, the adapter control unit 21 is used only when an abnormality occurs due to a sudden change in the patient's condition, a device attached to the patient dropping out, or a failure of the medical device 10. The call signal is generated and output to the nurse call slave unit 31, but the present invention is not limited to this. For example, when the medical device 10 is used, the adapter control unit 21 is disconnected from the medical device 10 and the nurse call interlock adapter 20 (that is, the formed communication path is disconnected). In this case, a call signal may be generated and output to the nurse call slave unit 31.

  In the above-described embodiment, the nurse call link adapter 20 does not notify the operation status of the own device, but is not limited thereto. For example, the nurse call link adapter 20 may be provided with an operation notification unit that notifies the operation status of the nurse call link adapter 20.

  Specifically, as means for notifying the operation status of the nurse call interlocking adapter 20, a display unit composed of an LED (Light Emitting Diode) or the like, an audio output unit composed of a speaker or the like (none of which are shown), etc. Is mentioned. When the nurse call interlocking adapter 20 is waiting (that is, the detection unit 23 has not detected a contact signal), the adapter control unit 21 causes the display unit to blink slowly. Further, the adapter controller 21 causes the sound output unit to output an intermittent sound with a long interval. In addition, when the nurse call interlocking adapter 20 receives the contact signal output from the medical device 10 (that is, when the detection unit 23 detects the contact signal and the timer unit 24 and the determination unit 25 are operated), the adapter for the adapter is used. The control unit 21 lights up the display unit. Further, the adapter controller 21 causes the sound output unit to output an intermittent sound with a short interval. Further, even when the timer unit 24 finishes measuring the time of 10 seconds, the determination unit 25 determines that the detection unit 23 continues to detect the contact signal output from the medical device 10 for 10 seconds or more. When the adapter control unit 21 outputs a call signal to the outside, the adapter control unit 21 switches the display unit that has been lit to blink quickly. Further, the adapter control unit 21 switches the audio output unit that has output intermittent sounds with short intervals so as to output continuous sounds.

  Thereby, the medical worker can confirm the state of operation of the nurse call interlocking adapter 20 visually or audibly. Of course, any one of the display unit and the audio output unit may be provided.

  In the above-described embodiment, when the signal output from the medical device 10 is continuously detected for a predetermined time, the adapter control unit 21 generates a call signal and outputs the call signal to the outside. It is not limited to this. For example, when the number of detected pulses forming the signal output from the medical device 10 exceeds a predetermined number within a predetermined time, the adapter control unit 21 generates a call signal and outputs it to the outside. You may do it.

  Specifically, it is realized by using a medical device linked nurse call system including a nurse call linked adapter 20 as shown in FIG. As shown in the figure, in this modification, the nurse call link adapter 20 is provided with a pulse detection unit 26, a count unit 27, and a count number determination unit 28 instead of the determination unit 25 of the embodiment shown in FIG. . Here, since the medical device 10 and the nurse call system 30 have the same configuration as that of the above-described embodiment, the description thereof is omitted. In addition, a ventilator is applied as the medical device 10.

  The pulse detection unit 26 detects a pulse forming the contact signal output from the medical device 10. The count unit 27 counts the number of times that the pulse detection unit 26 has detected a pulse. The count number determination unit 28 determines whether or not the number of times counted by the count unit 27 has reached a predetermined number or more until the timer unit 24 finishes measuring the preset time. Here, the contact signal output from the medical device 10 is formed by a plurality of pulses. Therefore, the contact signal temporarily output from the medical device 10 is formed with an extremely small number of pulses by causing an operation against forced ventilation such that the patient with the medical device 10 can throat. On the other hand, the contact signal continuously output from the medical device 10 due to the occurrence of an abnormality in the patient or the medical device 10 is formed of a large number of pulses. Therefore, in order to determine whether or not the contact signal output from the medical device 10 is due to the occurrence of an abnormality in the patient or the medical device 10, the medical worker uses a count number setting unit (not shown) to determine Set the number of times.

  Here, when the pulse detection unit 26 detects a pulse forming the contact signal output from the medical device 10, the adapter control unit 21 operates the count number determination unit 28, and the count number determination unit 28 performs processing. To start. Further, the adapter control unit 21 detects when the pulse detection unit 26 no longer detects a pulse forming the contact signal output from the medical device 10 or until a time set by the timer unit 24 in advance. When the measurement is performed, the operation of the count number determination unit 28 is stopped.

  Until the timer unit 24 finishes measuring the time set in advance, the count unit 28 does not count the number of times that the pulse detection unit 26 has detected a pulse. In other words, the timer unit 24 sets the time in advance. If the number of detected pulses is less than the number set in advance in the count number setting unit in the state of measuring up to the predetermined time, the adapter control unit 21 causes the patient or the medical device 10 to temporarily It is determined that an abnormality has occurred (that is, the fighting state has temporarily been reached). Therefore, the adapter control unit 21 does not generate a call signal (or does not output the generated call signal).

  On the other hand, until the timer unit 24 finishes measuring the preset time, the count unit 28 counts the number of times the pulse detection unit 26 detects the pulse. In other words, the timer unit 24 sets the preset number of times. If the number of times the pulse has been detected is equal to or greater than the number set in advance in the count number setting unit in the state of measuring up to the preset time, the adapter control unit 21 determines that the patient or medical device 10 It is determined that an abnormality has occurred (that is, an abnormality has occurred due to a sudden change in the patient's condition, a device attached to the patient falling off, or a failure of the medical device 10). Therefore, the adapter control unit 21 generates a call signal (or outputs the generated call signal).

  As a result, the call signal is generated and output to the outside only when the number of detections of the pulses forming the signal output from the medical device is equal to or greater than the predetermined number, and the nurse call system that inputs this is notified. Done. For this reason, there is no notification when a signal is temporarily output from a medical device. Therefore, the possibility that the nurse call parent device is called only when an abnormality occurs in a patient or a medical device is increased. Can do. Therefore, the medical worker is not called unnecessarily, and the business efficiency of the medical worker can be improved.

  In addition, the configuration, processing procedure, contents, and the like of the nurse call link adapter 20 and the medical device link nurse call system including the nurse call link adapter 20 can be variously modified and implemented without departing from the gist of the present invention. . Moreover, various inventions can be formed by combining a plurality of constituent elements disclosed in the embodiment. For example, you may make it delete a some component from all the components shown by embodiment. Furthermore, you may make it combine the component covering different embodiment suitably.
