Abstract

An abnormality level causing an alarm output and a continuation state of the abnormality are notified. A biological information monitoring apparatus that monitors biological information sets a volume range of an alarm sound so that a volume range corresponding to each level does not overlap each other for each level of abnormality that may occur during monitoring. If an abnormality occurs during monitoring, an alarm sound is output from the auditory alarm output unit at a volume within the volume range corresponding to the level of the abnormality that has occurred, and an auditory alarm output is output according to the duration of the abnormality that has occurred. The volume of the alarm sound output from the unit is changed within the corresponding volume range. [Selection] Figure 5

Description

  The present invention relates to a biological information monitor device, an alarm control method for a biological information monitor device, and an alarm control program for a biological information monitor device.

  The biological information monitoring apparatus can collectively display the measurement values and waveforms of biological information such as an electrocardiogram, blood pressure, and oxygen saturation on the display screen of the display. Examples of the biological information monitor device include a bedside monitor device that is installed and used at the bedside of a hospital room or the like, a central monitor device that is installed and used at a nurse station, or the like. Medical workers (such as doctors and nurses) can grasp the patient's condition by looking at the measurement values and waveforms displayed on the display screen.

  In addition, the biological information monitoring device generally outputs an alarm sound (output of an auditory alarm) or turns on an alarm indicator when any abnormality (for example, abnormality of biological information, abnormality of measuring equipment / measurement environment) occurs. It has an alarm function to notify the medical staff of the abnormality by performing an alarm output such as blinking (output of a visual alarm). Therefore, even if the medical staff does not always look at the display screen, he / she can notice the alarm output from the biological information monitor apparatus and immediately know the occurrence of the abnormality. Note that the alarm indicator is arranged at the top of the biological information monitor device, and a visual alarm can be confirmed from the side surface direction or the rear surface direction of the biological information monitor device.

As an example of a conventional biological information monitoring apparatus, there is one described in Patent Document 1, for example. In this biological information monitoring apparatus, a setting value called “priority” corresponding to the level of abnormality is set in advance in advance, and an alarm output mode corresponding to each priority is also set in advance in advance. When an abnormality of a biological signal or an abnormality of devices / environment occurs, an auditory alarm and a visual alarm are output in an output mode based on a priority according to the level of the abnormality. For example, the state in which the measured value of SpO ₂ is less than a predetermined threshold (for example, 90%) is a medium priority among the preset three levels of priority (low priority, medium priority, and high priority). It corresponds to. Therefore, when that state occurs, a medium priority alarm is output.

  Further, in this conventional biological information monitoring apparatus, when the alarm output is started and the duration thereof satisfies a predetermined condition, the priority of the alarm is changed, and the alarm output mode is also changed accordingly. It has become. For example, when the duration of the abnormality occurrence state has passed 5 minutes, the priority is changed from a priority at the beginning of alarm output (for example, medium priority) to a priority one level higher (for example, high priority). Then, the change of the alarm output mode (for example, increase in volume and increase in blinking speed) is performed along with the change in priority.

Japanese Patent No. 5909037

  However, in the above-described conventional biological information monitoring device, according to the duration of the alarm output, the priority of the alarm is different from the specific priority corresponding to the level of the abnormality that caused the alarm output. It is changed to another priority corresponding to the level. At this time, the level of the abnormality that caused the alarm output may not actually change at all. Therefore, there is a problem that it becomes difficult to identify the abnormal level itself.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a biological information monitor apparatus 100 according to an embodiment of the present invention.

  The biological information monitoring apparatus 100 includes a connector unit 101, a control unit 102, a storage unit 103, a display 104, an alarm indicator 105, a communication unit 106, a speaker 107, and operation buttons 120.

The connector unit 101 is a connector for connecting the biological information detection unit attached to the patient to the biological information monitor device 100. A biological information measuring device group 110 is connected to the connector unit 101. The biological information measuring device group 110 includes an electrocardiogram electrode 111 for detecting an electrocardiogram, a blood pressure measurement cuff 112 for detecting blood pressure, a body temperature sensor 113 for detecting body temperature, and SpO ₂ for detecting SpO _{2. 2} sensor 114, and a biological information detector such as a cardiac output sensor 115 for detecting cardiac output. The connector unit 101 functions as an interface between the biological information measuring device group 110 and the control unit 102. In addition to the biological information measuring device group 110, the connector unit 101 may be connected to a device used for treatment or treatment (hereinafter referred to as “therapeutic device”) such as a ventilator. In the present embodiment, the treatment device, the biological information measuring device group 110, and the biological information monitoring device 100 are collectively referred to as “devices”.

  The control unit 102 includes, for example, an arithmetic processing device such as a CPU (Central Processing Unit) and a memory device such as a RAM (Random Access Memory), and stores a program stored in a storage unit 103 (for example, a ROM (Read Only Memory)). The whole control of the biological information monitoring apparatus 100 and a predetermined measurement process are executed by deploying in the memory device and executing it by the arithmetic processing unit. With this measurement process, the control unit 102 measures the biological information of the patient using the biological information measuring device group 110 connected to the connector unit 101. Then, the control unit 102 detects an abnormality of the patient's biological information (hereinafter, referred to as “biological information related abnormality”) based on the measurement result. In addition, the control unit 102 detects an abnormality in the connection state between the biological information measurement device group 110 and the treatment device, an abnormality in devices and the environment (hereinafter referred to as “device information related abnormality”). The control unit 102 may receive notification of these abnormality detections from the outside of the biological information monitoring apparatus 100. Moreover, since the conventionally well-known thing is applicable about the measuring method of various biological information using the said biological information measuring device group 110, the detection method of biological information related abnormality, and the detection method of apparatus information related abnormality, here Detailed description thereof is omitted. The control unit 102 is an example of an “alarm setting unit” and an “alarm control unit”.

  The display 104 displays the biological information obtained by the measurement process of the control unit 102 in the form of measurement values or waveforms. The display 104 is a liquid crystal display with a touch panel, for example, and has not only a display function for displaying biological information but also a function as an input unit that receives an input operation by an operator. Specifically, the display 104 can accept an input by a touch operation from an operator for a display format of the display 104, a mode change of the biological information monitor device 100, an alarm setting, or the like.

  Furthermore, the biological information monitoring apparatus 100 has an operation button 120. As shown in FIG. 2, the operation button 120 is provided in the vicinity of the display 104 on the front surface of the biological information monitor device 100. FIG. 2 is an external view of the biological information monitor device 100 as viewed from the front. An alarm indicator 105 is provided on the upper portion of the housing of the biological information monitoring apparatus 100. The alarm indicator 105 is a lighting fixture using, for example, an LED (Light Emitting Diode) or the like, and turns red, for example, when the control unit 102 (FIG. 1) detects that a biological information related abnormality or a device information related abnormality has occurred. It is blinking. The alarm indicator 105 is an example of a visual alarm output unit. The output mode of the visual alarm by the alarm indicator 105 is set in the control unit 102 in advance, and the visual alarm is output in the output mode according to this setting.

  The operation button 120 includes a plurality of buttons. Examples of the operation button 120 include a power switch 121, a measurement start / stop button 122, a data recording button 123, an alarm sound stop button 124, and the like.

  The biological information monitor device 100 can communicate with other biological information monitor devices via the communication unit 106. Specifically, the biological information monitoring apparatus 100 can transmit the acquired biological information, the state of the own apparatus, and the like to the central monitoring apparatus or the like via the communication unit 106. Further, a control signal from the central monitor device can be input via the communication unit 106. The connection between the biological information monitoring apparatus 100 for communication by the communication unit 106 and the outside may be wired or wireless.

  The speaker 107 is an audio output device and is an example of an “auditory alarm output unit” that outputs an alarm as a sound. The speaker 107 outputs, for example, an electronic sound as an alarm sound (auditory alarm) when the control unit 102 (FIG. 1) detects that an abnormality has occurred in biological information, devices, or the environment. In addition to the alarm sound, the speaker 107 may output, for example, an R-wave synchronized sound of a heartbeat. The output mode of the audible alarm by the speaker 107 is set in advance in the control unit 102, and the audible alarm is output in the output mode according to this setting.

  The configuration of the biological information monitoring apparatus 100 according to the present embodiment has been described above.

  Next, an alarm control method for the biological information monitoring apparatus 100 will be described. Here, an alarm sound control method for changing the volume of an alarm sound according to the duration of occurrence of an abnormality will be described as an example with reference to FIG.

  First, in step S <b> 1, the control unit 102 performs alarm setting according to the operation of the operation button 120, the touch operation of the display 104, or the like.

  When the alarm setting is performed, the control unit 102 first causes the display 104 to display an alarm sound setting window as an alarm setting screen. FIG. 4 is a diagram illustrating an example of an alarm sound setting window. In this alarm sound setting window, an operation for setting a tone color and a volume can be input for each alarm type and for each alarm priority.

  In this embodiment, the alarm types that can be set are other than the biological information alarm for notifying abnormality related to biological information, the ventilator alarm for notifying the abnormality of the ventilator, and the abnormality of the ventilator. There are three types of device information alarms for notifying device information related abnormalities. The biological information alarm corresponds to a so-called vital alarm, and the ventilator alarm and the device information alarm correspond to a so-called technical alarm.

  Of the three types of alarms, for the biological information alarm and the device information alarm, the tone color and volume can be set for each alarm priority. In this embodiment, a low priority alarm with a relatively low degree of urgency is called a “status alarm”, a medium priority alarm with a medium degree of urgency is called a “caution alarm”, and the degree of urgency is A relatively high priority alarm is called an “emergency alarm”.

  Since the definition and definition of low priority, medium priority and high priority, and setting and control that can output an alarm in a different manner depending on the priority, are well known in the art, for example, as described in Patent Document 1, Detailed description thereof is omitted here. However, the alarm sound control method of the present embodiment is different from the prior art described in Patent Document 1 in that the priority itself is not changed even if the abnormal state continues and the priority at the time of occurrence of the abnormal state is maintained. To do.

  The timbre can be changed, for example, by touching a timbre setting button in the alarm sound setting window. Candidate timbres are stored in advance in the storage unit 103, and the timbre of the alarm sound is selected by touching the timbre setting button.

  The volume can be changed, for example, by swiping the slider up and down along the slide bar in the alarm sound setting window. In the example shown in FIG. 4, regarding the device information alarm sound, the volume of the emergency alarm is set to “7” in 10 levels, and the volume of the caution alarm is set to “4” in 10 levels. The volume of the status alarm is set to “3” in 10 levels. In the present embodiment, the settable range is limited in advance so that the alarm volume having a relatively lower priority does not exceed the alarm volume having a relatively higher priority.

  Note that the set value of the sound volume means a target value of the sound volume, but at which position in the sound field the sound volume of the target value can be changed in various ways.

  After the timbre and volume of the alarm sound are set, the control unit 102 sets an escalation alarm.

  In setting an escalation alarm, the control unit 102 causes the display 104 to display an escalation alarm setting window as another screen for setting an alarm. FIG. 5 is a diagram illustrating an example of an escalation alarm setting window. In this escalation alarm setting window, an operation for setting a volume range can be input for each alarm type and each alarm priority. More specifically, the operation performed here is an operation for setting the maximum value of the volume range. The minimum value of the volume range is determined in advance to the volume set in the alarm sound setting window. Therefore, in the escalation alarm setting window, the setting of the volume range can be completed only by determining the maximum value of the volume range.

  The escalation alarm is activated, for example, by touching an escalation activation button in the escalation alarm setting window and switching from “OFF” to “ON”. When the escalation enable button is “OFF”, the set volume range is invalid, and an escalation alarm such as a volume increase described later is not executed. Therefore, the alarm sound control method of the present embodiment that changes the alarm volume is based on the premise that the escalation enable button is “ON”.

  The maximum value of the volume range can be changed, for example, by swiping the slider up and down along the slide bar in the escalation alarm setting window. In the example shown in FIG. 4, regarding the device information alarm sound, the minimum value of the emergency alarm volume range is set to “7” in advance, and therefore the maximum value of the volume range is set to a value equal to or greater than “7”. You can choose from. In this example, the maximum volume of the emergency alarm of the device information alarm sound is set to “9”. Further, since the minimum value of the volume range of the caution alarm of the device information alarm sound is set to “4” in advance, the maximum value of the volume range can be selected from a value of “4” or more. However, since the minimum value of the volume range of the emergency alarm that is the higher-level alarm of the caution alarm is “7”, the value that can be selected as the maximum value of the volume range of the caution alarm is limited to less than “7”. Due to such setting restrictions, it is possible to avoid overlapping the volume range with the upper alarm. In this example, the maximum volume of the caution alarm of the device information alarm sound is set to “6”.

  The interval setting button in the escalation alarm setting window is a button for selecting an interval for changing the alarm volume. By touching this button, the number of seconds in the interval is selected.

  In the alarm sound control method of the present embodiment, when the escalation alarm is set, the alarm setting is completed.

  When the alarm setting is completed, in step S2, the control unit 102 waits for a monitoring start operation. In the present embodiment, the alarm setting is always performed before the monitoring is started. However, the alarm setting is not necessarily performed immediately before the monitoring is started, but the alarm setting may be completed in advance. In addition, the alarm setting may be changed during monitoring after monitoring is started.

  When the monitoring start operation is received (S2: YES), the control unit 102 controls each unit in the biological information monitoring apparatus 100 and starts monitoring the biological information of the patient. During monitoring, the control unit 102 determines whether there is a device information related abnormality and also determines whether there is a biological information related abnormality (step S3).

  If no abnormality has occurred (S3: NO), the process proceeds to step S4, and the control unit 102 determines whether or not a monitoring end operation has been performed. If there is a monitoring end operation (S4: YES), the process ends. If there is no monitoring end operation (S4: NO), the process returns to step S3.

  When a biological information related abnormality or device information related abnormality has occurred (S3: YES), in step S5, the control unit 102 outputs an alarm based on the content of the abnormality. As described above, the alarm includes an audible alarm and a visual alarm. Here, the description will be given focusing on the audible alarm, and a detailed description of the visual alarm will be omitted. In the present embodiment, if the abnormality that has occurred is a biological information-related abnormality, or an abnormality in a device or environment other than a ventilator, a state alarm, a caution alarm, depending on the level (that is, priority) of the abnormality Either an emergency alarm is output. The volume of the alarm to be output follows the alarm setting in step S1. More specifically, the initial output volume is a volume set using an alarm sound setting window (see FIG. 4).

  For example, in the state where the alarm volume is set as shown in FIG. 4 for each alarm type and for each alarm priority, as shown in FIG. 6, at a certain time t1 after the start of monitoring, as shown in FIG. Assume that an emergency alarm is output due to an abnormality. In this case, the output of the emergency alarm is started at the initial output volume “7” (see FIG. 4). Also, for example, as shown in FIG. 6, it is assumed that a caution alarm is output due to a device information related abnormality at a certain time t3 after the start of monitoring. In this case, the output of the caution alarm is started at the initial output volume “4” (see FIG. 4).

  When the output of the alarm sound is started, in step S6, the control unit 102 determines whether or not the abnormality occurrence state continues. When the abnormality occurrence state does not continue (S6: NO), the process proceeds to step S7, and the control unit 102 stops the alarm output. Then, the process proceeds to step S4. For example, if the device information related abnormality is resolved at a certain time t2 after the start of monitoring, the determination result in step S6 at that time is “NO”, and the output of the emergency alarm is stopped as shown in FIG. .

  When the abnormality occurrence state continues (S6: YES), in step S8, the control unit 102 determines whether or not the abnormality level has changed. The change in the abnormality level referred to here is a change in priority corresponding to the abnormal state that is occurring. If there is a change in the abnormal level (S8: YES), the process proceeds to step S5 in order to switch to the output of the alarm sound corresponding to the corresponding priority. If there is no change in the abnormality level (S8: NO), in step S9, the control unit 102 determines whether or not an alarm stop operation has been performed. If there is an alarm stop operation (S9: YES), the process proceeds to step S7. If there is no alarm stop operation (S9: NO), in step S10, the control unit 102 determines whether T seconds have elapsed since the alarm output at the current alarm volume started.

  Here, T seconds is the interval time set using the escalation alarm setting window (see FIG. 5) when the alarm is set in step S1. If this interval is set to “10 seconds” in advance, for example, the control unit 102 determines whether 10 seconds have elapsed since the start of alarm output at the current alarm volume. If T seconds have not elapsed since the start of alarm output at the current alarm volume (S10: NO), the process returns to step S6. If T seconds have elapsed (S10: YES), the process proceeds to step S11. move on.

  In step S11, the control unit 102 determines whether or not the current alarm volume is the maximum value in a preset volume range. This maximum value is the maximum value of the volume range set using the escalation alarm setting window (see FIG. 5) when the alarm is set in step S1.

  When the current alarm volume is not the maximum value (S11: NO), in step S12, the control unit 102 increases the alarm volume by one level from the current alarm volume. Here, it is assumed that a volume range is set for each alarm type and for each alarm priority as shown in FIG. Taking the time t4 shown in FIG. 6 as an example, the alarm volume of the caution alarm (due to device information related abnormality) output at this time is “4” which is not the maximum value. The alarm volume is increased from the current alarm volume “4” to “5”, which is one level higher. Further, taking the time t5 shown in FIG. 6 as an example, the alarm volume at this time is “5” which is not the maximum value, so the control unit 102 changes the alarm volume from the current alarm volume “5” to 1. Increase to “6” on stage.

  If the current alarm volume has already reached the maximum value (S11: YES), the volume cannot be increased any more, so the process returns to step S6 while maintaining the volume and continuing to output the alarm.

As a result, a situation where the volume of the caution alarm exceeds the volume of the emergency alarm does not occur. Or the situation where the volume of the status alarm is higher than the volume of the caution alarm does not occur. Thus, for example, even if a caution alarm is issued based on the SpO ₂ measurement result and continues for a long time, the alarm volume is the same as the emergency alarm as long as the SpO ₂ measurement result itself does not deteriorate significantly. There is no volume. Therefore, it is possible to suppress a possibility that a medical worker who notices the alarm misunderstands the level of the abnormality that has occurred. In addition, it is possible to grasp the level of the abnormality that has occurred and that the abnormality occurrence state has continued.

  In the above-mentioned alarm sound control method, the volume of the alarm sound is gradually changed by switching one step at a time interval (interval) set in advance. It may be changed at a stroke from a minimum volume to a maximum volume at a single stepwise change. Thereby, it is possible to notify the health care worker more reliably of the continuation of the abnormality occurrence state.

  In addition, for a relatively higher alarm, the range of increase when the volume is increased may be larger than that of a relatively lower alarm. As a result, the effect of notifying the medical staff that the abnormality occurrence state continues through the change in volume can be enhanced as the higher-order alarm is generated. You may make it expand the increase range of a volume, so that the continuation time of an abnormality occurrence state becomes long.

  In the above alarm control method, when changing the alarm volume, the volume is switched stepwise, but the change may be stepless. Whether the volume change is stepwise or stepless, an escalation alarm can be realized by gradually increasing the volume.

  In the above alarm control method, when changing the alarm volume, the volume is unilaterally increased. However, not only the volume increase but also the volume decrease may be included. Even if a volume change that is temporarily decreased is included, the effect of the escalation alarm can be realized if the volume change is performed in the direction of increasing as a whole. For example, as shown in FIG. 7 as a modified example, after the caution alarm output due to the device information related abnormality is started at time t11, the volume may be repeatedly increased and decreased from time t12 after T seconds have elapsed. . Further, from time t13 after the elapse of T seconds, the increase / decrease range of the volume may be expanded as compared to before time t13. Furthermore, from time t14 after the elapse of T seconds, the volume increase / decrease pitch may be reduced as compared to before time t14, and from time t15 after the elapse of T seconds, the sound volume increases compared to before time 15. The increase / decrease pitch may be further reduced. In FIG. 7, the time length of the large volume immediately after the volume increase and the time length of the small volume immediately after the volume decrease are the same in each interval after time t12 when the volume increase / decrease is repeated. The time length of the high volume may be made longer or shorter than the time length of the low volume. Further, as the elapsed time elapses, the time length of the large volume may gradually become longer than the time length of the small volume. In this way, the alarm emphasis method may be changed from a certain timing. In addition, higher-level alarms can be used to alert health care professionals that the abnormal state has continued through some change in sound, such as changing the pitch or changing the time distribution between high and low volumes. It is preferable to apply an alarm emphasis method so as to increase the degree. In particular, when the emphasis level in a certain emphasis method is saturated (for example, when the sound volume increases and reaches the maximum sound volume), another method of emphasis is added, such as changing the increase / decrease pitch of the sound volume, or another method. If the emphasis is changed to emphasis, an even more effective escalation alarm can be realized. In the modification shown in FIG. 7, this modification is also applied to an escalation alarm by a visual alarm by replacing a parameter relating to an auditory alarm such as “alarm volume” with a parameter relating to a visual alarm such as “alarm light quantity”. can do.

  As described above, according to the present embodiment, the control unit 102 of the biological information monitoring apparatus 100 corresponds the volume range of the alarm sound to each level for each level of abnormality that may occur during monitoring. Set the volume ranges so that they do not overlap each other, and if an abnormality occurs during monitoring, an alarm sound is output from the speaker 107 at a volume within the volume range corresponding to the level of the abnormality that has occurred, and Depending on the duration, the volume of the alarm sound output from the speaker 107 is changed within the corresponding volume range. As a result, it is possible to notify both the level of the abnormality causing the alarm output and the continuation state of the abnormality occurrence.

  The embodiment of the present invention has been described above. The above description is an illustration of a preferred embodiment of the present invention, and the scope of the present invention is not limited to this. That is, the description of the configuration of the apparatus and the shape of each part is an example, and it is obvious that various modifications and additions to these examples are possible within the scope of the present invention.

  For example, in the present embodiment, as an example of the alarm control method, an alarm sound control method is described in which the volume of the alarm sound is changed according to the duration of occurrence of the abnormality, but the alarm sound is changed according to the duration of occurrence of the abnormality. The pitch or pitch may be changed, or a single tone may be changed to a chord. Moreover, you may implement | achieve in the visual alarm like lighting / flashing of an alarm indicator instead of an auditory alarm like an alarm sound. In this case, for example, the sound volume can be similarly realized by replacing it with brightness, color, or the like.

  The present invention can be widely applied to a biological information monitoring apparatus having an alarm function.
