Description

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

The biological information monitoring device can collectively display measured 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 installed and used at the bedside of a hospital room, a central monitor device installed and used at a nurse station, and the like. Medical staff (doctors, nurses, etc.) can grasp the patient's condition by looking at the measured values and waveforms displayed on the display screen.

In addition, the biological information monitor device generally outputs an alarm sound (output of an auditory alarm) or lights an alarm indicator when some abnormality (for example, an abnormality in biological information, an abnormality in measuring equipment / measurement environment) occurs. It has an alarm function that notifies medical personnel of the abnormality by outputting an alarm such as blinking (output of a visual alarm). Therefore, the medical staff can notice the alarm output from the biological information monitor device and immediately know the occurrence of the abnormality even if he / she does not always look at the display screen. The alarm indicator is arranged at the top of the biometric information monitor device, and the visual alarm can be confirmed from the side direction or the back direction of the biometric information monitor device.

As an example of the conventional biological information monitoring device, there is, for example, the one described in Patent Document 1. In this biological information monitoring device, a set value called "priority" according to the level of abnormality is set internally in advance, and an alarm output mode according to each priority is also set internally in advance. When an abnormality in a biological signal or an abnormality in equipment / 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, a state in which the measured value of SpO ₂ is less than a predetermined threshold value (for example, 90%) is a medium priority among three preset priorities (low priority, medium priority, and high priority). Corresponds to. Therefore, when that state occurs, a medium priority alarm is output.

Further, in this conventional biological information monitoring device, if the duration of the alarm output meets a predetermined condition after the alarm output is started, the priority of the alarm is changed, and the output mode of the alarm is changed accordingly. It has become. For example, when the duration of the abnormal occurrence state elapses for 5 minutes, the priority is changed from the priority at the beginning of the alarm output (for example, medium priority) to the priority one step higher (for example, high priority). Then, the output mode of the alarm is changed (for example, the volume is increased and the blinking speed is increased) with the change of the priority.

Japanese Patent No. 5909037

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

An object of the present invention is a biometric information monitor device, an alarm control method of the biometric information monitor device, and a biometric information monitor device capable of notifying the level of the abnormality that caused the alarm output and the continuous state of the abnormality occurrence.

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 monitoring device 100 according to an embodiment of the present invention.

The biological information monitor device 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 an operation button 120.

The connector unit 101 is a connector for connecting the biological information detection unit attached to the patient to the biological information monitoring device 100. The biological information measuring device group 110 is connected to the connector unit 101. The biological information measuring device group 110 includes an electrocardiographic electrode 111 for detecting an electrocardiogram, a cuff 112 for measuring blood pressure for detecting blood pressure, a body temperature sensor 113 for detecting body temperature, and SpO for detecting SpO _{2. 2} Sensor 114, a biological information detection unit such as a cardiac output sensor 115 for detecting a cardiac output, and the like are included. The connector unit 101 functions as an interface between the biometric information measuring device group 110 and the control unit 102. In addition to the biological information measuring device group 110, a device used for treatment or treatment (hereinafter referred to as "therapeutic device") such as a respirator may be connected to the connector unit 101. 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 unit 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)). By expanding it to a memory device and executing it by an arithmetic processing unit, the entire control of the biological information monitoring device 100 and a predetermined measurement process are executed. By this measurement process, the control unit 102 measures the biometric information of the patient using the biometric information measuring device group 110 connected to the connector unit 101. Then, the control unit 102 detects an abnormality in 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 measuring device group 110 and the treatment device, and an abnormality in the 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 device 100. Further, as a method for measuring various biological information using the above-mentioned biological information measuring device group 110, a method for detecting a biological information-related abnormality, and a method for detecting a device information-related abnormality, conventionally known methods can be applied. The detailed description thereof will be 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 measured values or waveforms. The display 104 is, for example, a liquid crystal display with a touch panel, and not only has a display function for displaying biological information, but also has a function as an input unit for receiving an input operation by an operator. Specifically, the display 104 can receive input by touch operation from the operator for the display format of the display 104, the mode change of the biological information monitor device 100, the alarm setting, and the like.

Further, the biological information monitoring device 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 monitoring device 100. Note that FIG. 2 is an external view of the biological information monitoring device 100 as viewed from the front direction. An alarm indicator 105 is provided on the upper part of the housing of the biological information monitoring device 100. The alarm indicator 105 is, for example, a lighting fixture using 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 supposed to blink. 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 advance in the control unit 102, and the visual alarm is output in the output mode according to this setting.

The operation button 120 is composed of a plurality of buttons. The operation button 120 includes, for example, 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 monitoring device 100 can communicate with other biological information monitoring devices via the communication unit 106. Specifically, the biological information monitoring device 100 can transmit the acquired biological information, the state of the own device, and the like to the central monitoring device and the like via the communication unit 106. Further, the control signal from the central monitor device can be input via the communication unit 106. The connection between the biometric information monitoring device 100 for communication by the communication unit 106 and the outside may be wired or wireless.

The speaker 107 is a voice 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 synchronization sound of a heartbeat. The output mode of the auditory alarm by the speaker 107 is set in advance in the control unit 102, and the auditory alarm is output in the output mode according to this setting.

The configuration of the biological information monitoring device 100 of the present embodiment has been described above.

Next, the alarm control method of the biological information monitoring device 100 will be described. Here, with reference to FIG. 3, an alarm sound control method for changing the volume of the alarm sound according to the duration of occurrence of an abnormality will be described as an example.

First, in step S1, the control unit 102 sets an alarm according to an operation of the operation button 120, a touch operation of the display 104, or the like.

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

In the present embodiment, the alarm types that can be set are other than the biological information alarm for notifying the abnormality related to biological information, the artificial respirator 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 the present embodiment, a low-priority alarm with a relatively low urgency is called a "state alarm", and a medium-priority alarm with a medium urgency is called a "caution alarm". Relatively high priority alarms are called "emergency alarms".

The definitions of low priority, medium priority, and high priority, and the setting and control that enable the output of alarms in different modes depending on the priority are well known, for example, as described in Patent Document 1. The detailed description thereof will be 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 when the abnormal state occurs is maintained. To do.

The tone can be changed, for example, by touching the tone setting button in the alarm sound setting window. The candidate tone color is stored in the storage unit 103 in advance, and the tone color of the alarm sound is selected by the touch operation of the tone color setting button.

The volume can be changed, for example, by swiping the slider up or 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 steps, and the volume of the caution alarm is set to "4" in 10 steps. The volume of the status alarm is set to "3" out of 10 levels. In the present embodiment, the settable range is limited in advance so that the alarm volume of the relatively lower priority does not become equal to or higher than the alarm volume of the relatively higher priority.

The volume setting value means the target value of the volume, but the position in the sound field where the volume of the target value is set can be variously changed.

After setting the timbre and volume of the alarm sound, the control unit 102 sets the escalation alarm.

In setting the escalation alarm, the control unit 102 causes the display 104 to display the escalation alarm setting window as another screen for setting the alarm. FIG. 5 is a diagram showing an example of an escalation alarm setting window. In this escalation alarm setting window, it is possible to input an operation for setting the volume range 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 predetermined 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 the escalation enable button in the escalation alarm setting window to switch from "OFF" to "ON". When the escalation enable button is "OFF", the set volume range is invalidated, and the escalation alarm such as 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 or 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 volume range of the emergency alarm is set to "7" in advance, so the maximum value of the volume range is set to "7" or more. 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 the values of "4" or more. However, since the minimum value of the volume range of the emergency alarm, which is the upper 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 duplication of 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 the interval for changing the alarm volume. The number of seconds in the interval is selected by touching this button.

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 the monitoring start operation. In the present embodiment, the alarm setting is always performed before the start of monitoring, but the alarm setting may be completed in advance, not necessarily immediately before the start of monitoring. Further, after the start of monitoring, the alarm setting may be changed during monitoring.

When the monitoring start operation is accepted (S2: YES), the control unit 102 controls each unit in the biological information monitoring device 100 to start monitoring the patient's biological information. During monitoring, the control unit 102 determines the presence or absence of an abnormality related to device information and also determines the presence or absence of an abnormality related to biological information (step S3).

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

When a biological information-related abnormality or a device information-related abnormality occurs (S3: YES), in step S5, the control unit 102 outputs an alarm based on the content of the abnormality. As described above, there are two types of alarms, an auditory alarm and a visual alarm. However, the auditory alarm will be mainly described here, and a detailed description of the visual alarm will be omitted. In the present embodiment, if the generated abnormality is a biometric information-related abnormality, or an abnormality in equipment other than the respirator or the environment, a state alarm and a caution alarm are given according to the level (that is, priority) of the abnormality. Or one of the emergency alarms is output. The output alarm volume follows the alarm setting in step S1. More specifically, the initial output volume is a volume set using the alarm sound setting window (see FIG. 4).

For example, in a 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, device information is related at a certain time t1 after the start of monitoring. It is assumed that an emergency alarm is output due to an abnormality. In this case, the emergency alarm output is started at the initial output volume "7" (see FIG. 4). Further, for example, as shown in FIG. 6, it is assumed that a caution alarm is output due to an abnormality related to device information at a certain time t3 after the start of monitoring. In this case, the caution alarm output 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 abnormal occurrence state continues. If the abnormal 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 becomes "NO", and as shown in FIG. 6, the output of the emergency alarm is stopped. ..

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 level of abnormality referred to here is a change in priority corresponding to the abnormal state during occurrence. 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 according to the corresponding priority. If there is no change in the abnormal level (S8: NO), in step S9, the control unit 102 determines whether or not there has been an alarm stop operation. 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 or not T seconds have elapsed since the alarm output at the current alarm volume started.

Here, the T second is the time of the interval set by using the escalation alarm setting window (see FIG. 5) at the time of setting the alarm in step S1. When this interval is set to, for example, "10 seconds" in advance, the control unit 102 determines whether or not 10 seconds have elapsed since the alarm output at the current alarm volume started. If T seconds have not elapsed since the alarm output at the current alarm volume started (S10: NO), the process returns to step S6, and 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 the preset volume range. This maximum value is the maximum value of the volume range set by 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 step from the current alarm volume. Here, it is assumed that the 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 (caused by the device information-related abnormality) output at this time is "4", which is not the maximum value, so that the control unit 102 , The alarm volume is increased from the current alarm volume "4" to "5", which is one step higher. Further, taking the time t5 shown in FIG. 6 as an example, since the alarm volume at this point is not the maximum value "5", the control unit 102 sets the alarm volume from the current alarm volume "5" to 1. Increase to "6" on the stage.

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

As a result, the situation where the volume of the caution alarm becomes higher than the volume of the emergency alarm does not occur. Alternatively, the situation where the volume of the status alarm becomes higher than the volume of the caution alarm does not occur. Therefore, for example, even if a caution alarm is issued based on the measurement result of SpO ₂ and then continues for a long time, the alarm volume is the same as the emergency alarm unless the measurement result of SpO ₂ itself is significantly deteriorated. There is no volume. Therefore, it is possible to reduce the possibility that the medical staff who notices the alarm misunderstands the level of the abnormality that has occurred. Moreover, it is possible to grasp the level of the abnormality that has occurred and the fact that the abnormality occurrence state has continued.

In the above 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, but it is not step by step but within the corresponding volume range. The volume may be changed at once by switching from the minimum volume to the maximum volume in one step. As a result, it is possible to more reliably notify the medical staff of the continuation of the abnormal occurrence state.

Further, for a relatively high-level alarm, the amount of increase when the volume is increased may be larger than that of the relatively low-level alarm. As a result, the effect of making the medical staff aware that the abnormal occurrence state remains continuous through the change in volume can be enhanced as the alarm is higher. As the duration of the abnormal occurrence state becomes longer, the increase range of the volume may be increased.

Further, in the above alarm control method, when the alarm volume is changed, the volume is switched stepwise, but the change may be stepless. Regardless of whether the volume change is stepwise or stepless, the escalation alarm can be realized by gradually increasing the volume.

Further, in the above alarm control method, when the alarm volume is changed, the volume is unilaterally increased, but not only the increase in the volume but also the decrease in the volume may be included. Even if a volume change that is temporarily reduced is included, the effect of the escalation alarm can be realized if the volume change is performed in the direction of increasing the volume 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 / decreased from time t12 after T seconds have elapsed. .. Further, from the time t13 after the lapse of T seconds, the increase / decrease range of the volume may be expanded as compared with the time t13 or earlier. Further, from the time t14 after the lapse of T seconds, the pitch of increase / decrease in volume may be reduced as compared with the time before time t14, and further, from the time t15 after the lapse of T seconds, the volume may be reduced as compared with the time before time 15. The increase / decrease pitch of may be further reduced. In FIG. 7, the time length of the loud volume immediately after the volume increase and the time length of the low volume immediately after the volume decrease are the same in each interval after the time t12 in which the volume increase / decrease is repeated, but the present invention is not limited to this. , The loud time length may be made longer or shorter than the low volume time length. Further, as the elapsed time elapses, the time length of the loud volume may be gradually longer than the time length of the low volume. In this way, the alarm emphasis method may be changed from a certain timing. In addition, the effect of making the medical staff aware that the abnormal occurrence state continues through some change related to sound, such as changing the pitch or changing the time allocation between loud and quiet, is a higher alarm. It is preferable to apply the alarm enhancement method so as to increase the degree. In particular, when the emphasis level in one enhancement method is saturated (for example, the volume increases and reaches the maximum volume), the emphasis is added by another method, such as changing the pitch for increasing or decreasing the volume, or another method. A more effective escalation alarm can be realized by changing the emphasis to. In the modified example shown in FIG. 7, by replacing the parameters related to the auditory alarm such as "alarm volume" with the parameters related to the visual alarm such as "alarm light amount", this modified example is also applied to the escalation alarm by the visual alarm. can do.

As described above, according to the present embodiment, the control unit 102 of the biological information monitoring device 100 corresponds to the volume range of the alarm sound for each level of abnormality that may occur during monitoring. If the volume range is set so that they do not overlap with each other and 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 occurrence of the abnormality, and the occurrence of the abnormality occurs. The volume of the alarm sound output from the speaker 107 is changed within the corresponding volume range according to the duration. As a result, it is possible to notify the level of the abnormality that caused the alarm output and the continuous state of the occurrence of the abnormality.

The embodiments of the present invention have been described above. The above description is an example of a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. That is, the description of the configuration of the device and the shape of each part is an example, and it is clear that various changes 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 in which the volume of the alarm sound is changed according to the duration of the abnormality occurrence is given, but the alarm sound is given according to the duration of the abnormality occurrence. You may change the pitch or pitch of, or change from a single note to a chord. Further, it may be realized by a visual alarm such as lighting / blinking of an alarm indicator instead of an auditory alarm such as an alarm sound. In this case, for example, the 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 device having an alarm function.
