Detailed Description

Referring to fig. 1, based on the above-mentioned problems, the present invention provides an adaptive alarm system, which can be applied to devices such as a monitor. The adaptive alarm system comprises: acquisition module 10, alarm module 20 and control module 30.

The acquisition module 10 is configured to acquire a measurement signal of a subject.

The control module 30 is used for receiving and analyzing the measurement signals from the parameter acquirer to acquire a main control parameter and a reference parameter, and outputting a first alarm instruction aiming at the main control parameter and controlling an alarm refractory period for starting the main control parameter when the main control parameter exceeds a normal range; in the alarm refractory period, adjusting the duration of the alarm refractory period according to the main control parameter and the reference parameter; the alarm module 20 is configured to alarm the master control parameter when receiving the first alarm instruction. It can be understood that, adjusting the duration of the alarm refractory period includes shortening the alarm refractory period, extending the alarm refractory period, canceling the alarm refractory period, modifying the default alarm refractory period, setting the next alarm refractory period, and the like, so long as the alarm refractory period is adjusted, and the invention is not limited herein.

In an embodiment, the control module 30 is further configured to output a second alarm instruction for the master control parameter when the master control parameter exceeds a normal range and the reference parameter exceeds a preset range; the alarm module 20 is further configured to alarm the master control parameter when at least one of the first alarm instruction or the second alarm instruction is received. It can be appreciated that the manner of adjusting the alarm refractory period in this embodiment may be to shorten the alarm refractory period or interrupt the alarm refractory period, so that the second alarm instruction may be issued during the alarm refractory period. The alarm refractory period of the master control parameter only limits the alarm of the master control parameter, that is, in the alarm refractory period, when only the master control parameter exceeds a normal range and the reference parameter does not exceed a preset range, the first alarm instruction is not output. On the other hand, the reference parameters also have corresponding normal ranges, and the alarm refractory period of the main control parameters does not affect the output of the alarm instruction for the reference parameters by the control module 30. The control module 30 is further configured to output an alarm command for the reference parameter when the reference parameter is outside its normal range.

In an embodiment, when the main control parameter exceeds a normal range, outputting a first alarm instruction aiming at the main control parameter, and when the main control parameter falls back to the normal range, controlling to start an alarm refractory period of the main control parameter; when the main control parameter continuously exceeds the normal range and does not fall back into the normal range, the first alarm instruction is continuously output, and the alarm refractory period is not entered. When the main control parameters exceed the normal range, a first alarm instruction is output and then falls back to the normal range, an alarm refractory period is started, and alarm shielding is carried out on the condition that the main control parameters generated in the alarm refractory period exceed the normal range and the reference parameters do not exceed the preset range.

In the present application, when the physiological state of the subject is normal, the main control parameters of the subject are located in the normal range, the alarm condition is not satisfied, and the alarm module 20 does not alarm. When the physiological state of the monitored object is abnormal, the main control parameter of the monitored object exceeds the normal range and meets the original alarm condition, the control module 30 sends out a first alarm instruction, and the alarm module 20 receives the first alarm instruction to alarm the main control parameter; meanwhile, an alarm refractory period for the main control parameter is started, and the control module 30 does not output a first alarm instruction when only the condition that the main control parameter exceeds the normal range again exists in the alarm refractory period. However, in the alarm refractory period, when the main control parameter exceeds the normal range and the reference parameter of the monitored object exceeds the preset range, the physiological state of the monitored object is deteriorated, and at this time, the alarm module 20 alarms the main control parameter again even in the alarm refractory period of the main control parameter. It will be appreciated that in this case, the individual alarms of alarm module 20 on the reference parameter are not affected. When the reference parameter exceeds the corresponding normal range, the control module 30 can also send an alarm instruction for the reference parameter, and control the alarm module 20 to alarm the reference parameter.

Therefore, in the self-adaptive alarm system, when the physiological state of the monitored object is deteriorated at a certain moment, and the reference parameter of the monitored object exceeds the preset range, even if the moment is in the alarm refractory period of the main control parameter, the alarm module 20 can still alarm the main control parameter, so that the physiological state of the monitored object can be timely found to be deteriorated in the alarm refractory period, and the probability of danger of the monitored object is reduced.

In this application, the main control parameters of the subject include: ventricular premature beat morphology, heart rate, blood oxygen, blood pressure, and other physiological parameters. The reference parameters of the subject may also include: ventricular premature beat morphology, heart rate, blood oxygen, blood pressure, and other physiological parameters. The physiological parameters included in the reference parameters and the physiological parameters included in the main control parameters can be the same kind of parameters or different kinds of parameters. Therefore, the condition that the reference parameter exceeds the preset range and the physiological state of the patient is deteriorated includes the condition that the physiological parameter of the same kind as the main control parameter exceeds the preset range and also includes the condition that the physiological parameter of the different kind from the main control parameter exceeds the preset range. If the reference parameter exceeds the preset range, it means that the physiological state of the subject is deteriorated, for example, the ventricular premature beat of the subject is increased, the degree of exceeding the alarm limit is increased, the heart rate exceeds the alarm limit, for example, the blood oxygen is reduced, the blood pressure is increased, and the alarm module 20 still alarms the master control parameters even in the alarm refractory period of each master control parameter.

In an embodiment, the physiological parameter included in the reference parameter and the physiological parameter included in the master parameter are the same kind of parameters. The ventricular premature beat pattern and the heart rate will be described by way of example.

The main control parameter is ventricular premature beat, and the reference parameter is ventricular premature beat. When the ventricular premature beat pattern is more severe than the normal range and the alarm is generated, the alarm module 20 alarms the ventricular premature beat even if the alarm of the ventricular premature beat pattern is in the refractory period.

The master parameter is heart rate and the reference parameter is heart rate. When the heart rate exceeds the normal range, namely, the heart rate exceeds the original alarm condition, after the heart rate overrun alarm is given, if the degree of the heart rate exceeding the original alarm condition is obviously increased compared with the degree of the heart rate exceeding the original alarm condition, the heart rate exceeds the preset range of the heart rate, the heart rate is in a worsening condition, and at the moment, even if the alarm aiming at the heart rate is in the alarm refractory period, the alarm module 20 still gives an alarm to the heart rate. It will be appreciated that an increase in the extent to which the original alarm condition is exceeded may include both an increase in the value and a decrease in the value. In one embodiment, the normal range of heart rates is greater than or equal to 80 and less than or equal to 120. The preset range of heart rate may be set to a preset upper range of greater than 120 and less than or equal to 160 and a preset lower range of less than or equal to 60, respectively. Accordingly, an increase in the extent to which the original alarm condition is exceeded may include the following two cases. First, when the heart rate is 125, the heart rate overrun alarm is triggered beyond the normal range, and then the heart rate exceeds 160 and exceeds the preset upper limit range, which belongs to the condition that the degree of exceeding the original alarm condition is increased. Second, when the heart rate is 75, the normal range is exceeded, the heart rate overrun alarm is triggered, and then when the heart rate is further reduced to 59, the range exceeds the preset lower limit, and the condition that the degree of exceeding the original alarm condition is increased is also included. Both of the above cases are cases where the degree to which the heart rate exceeds the original alarm condition increases, at which time the alarm module 20 still alarms the heart rate even if the alarm for the heart rate is still in the alarm refractory period.

In another embodiment, the physiological parameters included in the reference parameter and the physiological parameters included in the master parameter are different kinds of parameters. The reference parameter is associated with the master parameter in a medical sense, for example, a user often diagnoses a patient by combining two or more parameters, and one of the two or more parameters is the master parameter, and the rest are the reference parameters. Such as heart rate and ventricular premature beat morphology. It will be appreciated that in this case, the preset range of the reference parameter is independent of its normal range, and the preset range may be the same as its normal range, or may be smaller or larger than its normal range, and is not limited herein.

In one embodiment, the predetermined range of the reference parameter is the same as its normal range. The main control parameter is ventricular premature beat, and the reference parameter is heart rate; when the ventricular premature beat exceeds the normal range and the alarm is generated, the ventricular premature beat is unchanged, but the heart rate exceeds the normal range, which is worsened, and the alarm module 20 alarms the ventricular premature beat even in the alarm refractory period of the ventricular premature beat. And the following steps: when the ventricular premature beat pattern exceeds the normal range and an alarm is generated, the ventricular premature beat pattern is unchanged, but the hemodynamic parameters of the subject are deteriorated, such as blood oxygen reduction or blood pressure rise, which exceeds the normal range of blood pressure, and the situation is also deteriorated, and the alarm module 20 still alarms the ventricular premature beat even in the alarm refractory period of the ventricular premature beat. In this case, during the alarm refractory period of the master control parameter, the reference parameter associated with the master control parameter reaches an independent original alarm condition, and exceeds the normal range, and the control module 30 controls the alarm module 20 to alarm the master control parameter. It will be appreciated that at this point, the control module 30 is not affected by controlling the alarm of the reference parameter by the alarm module 20, and since the reference parameter is also out of its corresponding normal range, the alarm for the reference parameter may be initiated at this point as well.

In another embodiment, the preset range of the reference parameter is not the same as its normal range. The main control parameter is heart rate, and the reference parameter is ventricular premature beat. The upper limit of the normal range of the heart rate is 120, the heart rate when triggering the heart rate overrun alarm is 125, the normal range of the ventricular premature beat form is less than or equal to 4, and the preset range is less than or equal to 2. During the alarm refractory period of the heart rate, when the heart rate exceeds the normal range by 125, the ventricular premature beat morphology becomes more, for example, from 1 to 3, at which time the alarm module 20 still alarms the heart rate even during the alarm refractory period of the heart rate, and the ventricular premature beat morphology does not reach its normal range but has exceeded the preset range. In this case, during the alarm refractory period, the reference parameter associated with the main control parameter does not reach the individual alarm condition, does not exceed the normal range thereof, but exceeds the preset range, so that the physiological state of the patient is still considered to have a trend of worsening, and the alarm module 20 also alarms the first physiological parameter. However, in this case, since the reference parameter is not out of the normal range, the control module 30 does not control the alarm module 20 to alarm the reference parameter.

The control module 30 is further configured to control the alarm module 20 to alarm at least one physiological parameter when the at least one physiological parameter of the master control parameter or the reference parameter exceeds a corresponding normal range; and in the alarm refractory period of the main control parameter, if the main control parameter exceeds the normal range and the reference parameter does not exceed the corresponding preset range, not alarming the main control parameter again. In this way, the master control parameter or the reference parameter may be one physiological parameter, two physiological parameters or more, which is not limited herein.

When the main control parameter and the reference parameter only comprise one physiological parameter, if the physiological parameter exceeds the normal range, the alarm module 20 alarms the physiological parameter, and the control module 30 starts an alarm refractory period of the physiological parameter; if the physiological parameter does not exceed the preset range and the current time is within the alarm refractory period of the physiological parameter, the alarm module 20 does not alarm the physiological parameter any more.

When the master control parameter includes a first physiological parameter and a second physiological parameter, the first physiological parameter and the second physiological parameter are not related, and the first physiological parameter and the second physiological parameter both exceed corresponding normal ranges, the control module 30 controls the alarm module 20 to alarm the first physiological parameter and the second physiological parameter, and when the first physiological parameter and the second physiological parameter fall back to the normal ranges, the alarm refractory period for the first physiological parameter and the alarm refractory period for the second physiological parameter are started; if neither the first physiological parameter nor the second physiological parameter exceeds the corresponding preset range, and the current time is within the alarm refractory period corresponding to the first physiological parameter and the second physiological parameter, the alarm module 20 does not alarm the first physiological parameter and the second physiological parameter any more. That is, the type of physiological parameter included in the master parameter may be one or more, and likewise, the type of physiological parameter included in the reference parameter may be one or more, which is not limited herein.

The control module 30 is further configured to control the alarm module 20 to alarm at least one physiological parameter when the at least one physiological parameter of the master control parameter or the reference parameter exceeds a corresponding normal range and the current time is not within the alarm refractory period. That is, the alarm module 20 directly alarms the physiological parameter beyond the normal range when any physiological parameter is abnormal outside the alarm refractory period.

The control module 30 is further configured to extend the time of the alarm refractory period of the master control parameter when the number of times that the master control parameter exceeds the corresponding normal range but the reference parameter does not exceed the corresponding preset range is greater than the preset number of times during the alarm refractory period. The time of the current alarm refractory period of the main control parameter can be prolonged, and the time of the next alarm refractory period of the main control parameter can also be prolonged. That is, during the current alarm refractory period, the number of times that the detected master control parameter exceeds the normal range and the reference parameter does not exceed the corresponding preset range exceeds the preset number of times, which indicates that the alarm condition of the master control parameter is frequent during the period, and the control module 30 controls to extend the alarm refractory period time of the current or next physiological parameter. Therefore, after the time of the alarm refractory period is prolonged, the alarm of the master control parameters under the same condition can be reduced, repeated alarm is reduced, and the problem of fatigue of the alarm is reduced.

For example, in one embodiment, when the master and reference parameters are heart rates, the normal range of heart rates is greater than or equal to 80 and less than or equal to 120. The preset range of heart rate may be set to a preset upper range of greater than 120 and less than or equal to 160 and a preset lower range of less than or equal to 60, respectively. If the heart rate exceeds 120 and the frequency of not exceeding 160 is greater than the preset frequency in the alarm refractory period, the alarm refractory period is prolonged. In another embodiment, the primary control parameter is heart rate and the reference parameter is ventricular premature beat. The upper limit of the normal range of the heart rate is 120, the preset range of the ventricular premature beat form is less than or equal to 2, and when the heart rate exceeds 120 and the number of times that the ventricular premature beat form does not exceed 2 is greater than the preset number of times in the alarm refractory period of the heart rate, the alarm refractory period is prolonged.

In the present application, the extension of the alarm refractory period may be an extension of the alarm refractory period of one physiological parameter, two physiological parameters or more physiological parameters, which is not limited herein.

The control module 30 is further configured to set the extended alarm refractory period to a default alarm refractory period after the number of times of extending the time of the alarm refractory period exceeds a preset threshold. That is, when it is detected that the number of times that the physiological parameter exceeds the corresponding normal range but does not exceed the corresponding preset range in the alarm refractory period is greater than the preset number of times, and the number of times that the alarm refractory period is prolonged exceeds the preset threshold, the control module 30 automatically sets the prolonged alarm refractory period to be the default alarm refractory period, that is, the effective time of the subsequent alarm refractory period is the prolonged alarm refractory period. The extended duration of the alarm refractory period may be obtained from altering the duration of each alarm refractory period prior to the default alarm refractory period, e.g., the extended duration of the alarm refractory period is an average of the durations of each alarm refractory period prior. It will be appreciated that the preset number of times may be 1, i.e. the default alarm refractory period is modified after a time extending the alarm refractory period. The preset times can be more than or equal to 2, after the time of multiple prolonged alarm refractory periods is needed to be generated, the state of the patient is further determined to be more suitable for the longer alarm refractory periods, and the prolonged alarm refractory periods are modified into default alarm refractory periods.

The control module 30 is further configured to generate a corresponding relationship according to the number of times that the physiological parameter exceeds the normal range but does not exceed the preset range in the alarm refractory period and the corresponding extension time of the alarm refractory period, and determine the extension time of the alarm refractory period according to the number of times that the real-time master control parameter satisfies the original alarm condition and the corresponding relationship.

That is, after the control module 30 prolongs the time of the alarm refractory period a plurality of times, the control module 30 may generate a corresponding relationship according to a specific number of times the detected master control parameter exceeds the normal range in a period of time and a specific time of the corresponding prolonged alarm refractory period, so that according to the corresponding relationship, and according to a number of times the master control parameter exceeds the normal object monitored in real time next, the prolonged time of the alarm refractory period may be determined, thereby adaptively prolonging the time of the alarm refractory period. It will be appreciated that in one embodiment, similar approaches may also be employed to adaptively shorten the time of the alarm refractory period, or even cancel the alarm refractory period.

The time of the alarm refractory period is adaptively adjusted, so that the possible danger of a monitored object caused by long-time non-alarm when the physiological condition of the monitored object is deteriorated can be avoided, and the technical problem of alarm fatigue caused by repeated alarm is also avoided.

The self-adaptive alarm system also comprises a display, wherein the display is used for displaying the trend graph and the normal range of the main control parameters, and the main control parameters can be intuitively seen from the display to exceed the normal range. The display can also display the duration of the alarm refractory period, so that the main control parameter can be intuitively seen on the display to be beyond the normal range, and the reason that the system does not alarm is that the system is positioned in the alarm refractory period. The display may also display reference parameters and/or preset ranges, from which the user may intuitively see that the reference parameters are outside the preset ranges.

In conclusion, the self-adaptive alarm system provided by the invention can still alarm the main control parameters in the alarm refractory period, avoid the alarm omission caused by setting the alarm refractory period, and timely find the danger of worsening of the physiological state of a monitored object and alarm. On the other hand, the flexible setting of the self-adaptive alarm system for the alarm refractory period can not only meet the requirement that the physiological state of a patient can be still alarmed even in the refractory period when the physiological state of the patient is deteriorated, but also prolong the refractory period length to reduce repeated alarm, and simultaneously can also automatically prolong the refractory period length to reduce repeated alarm.

In this application, each module of the adaptive alarm system may be a software module running in the monitor.

Referring to fig. 2, the present invention provides an adaptive alarm method, which can be applied to the adaptive alarm system and the corresponding medical equipment such as a monitor, and includes:

s1, acquiring a measurement signal of a subject.

S2, receiving and analyzing the measurement signals to obtain a main control parameter and a reference parameter, and outputting a first alarm instruction aiming at the main control parameter and controlling an alarm refractory period for starting the main control parameter when the main control parameter exceeds a normal range;

in the alarm refractory period, when the main control parameter exceeds a normal range and the reference parameter exceeds a preset range, adjusting the duration of the alarm refractory period;

and S3, alarming the main control parameters when the first alarming instruction is received.

The parameter types included in the reference parameter and the parameter types included in the master control parameter may be the same or different.

In an embodiment, the reference parameter is associated with the master parameter, and the controlling of the alarm refractory period that initiates the master parameter comprises: and in the alarm refractory period, if the main control parameter exceeds the normal range, and the reference parameter exceeds the preset range and does not exceed the normal range of the reference parameter, the alarm only alarms the main control parameter.

Outputting a second alarm instruction aiming at the main control parameter according to the main control parameter and the reference parameter in the alarm refractory period; "comprising: outputting a second alarm instruction aiming at the main control parameter when the main control parameter exceeds a normal range and the reference parameter exceeds a preset range in the alarm refractory period; and alarming the main control parameter when at least one of the first alarm instruction or the second alarm instruction is received.

Wherein when the reference parameter is associated with the master parameter, the "control starts the alarm refractory period of the master parameter" includes: and in the alarm refractory period, if the main control parameter exceeds the normal range, and the reference parameter exceeds the preset range and does not exceed the normal range of the reference parameter, the alarm only alarms the main control parameter.

The self-adaptive alarm method further comprises the following steps:

s5, alarming at least one parameter in the main control parameters or the reference parameters under the condition that the at least one parameter exceeds the corresponding normal range and the corresponding alarm refractory period is out of the current moment. That is, in the case that any one of the parameters exceeds the corresponding normal range outside the alarm refractory period of the parameter, and any one of the parameters is abnormal, the alarm module 20 directly alarms the parameter exceeding the normal range.

The self-adaptive alarm method further comprises the following steps:

s6, determining the times that the main control parameter exceeds the normal range and the reference parameter is positioned in the preset range in the current alarm refractory period, and prolonging the time of the alarm refractory period when the times are larger than the preset times. That is, during the alarm refractory period, the number of times that the detected master control parameter exceeds the normal range exceeds the preset number of times, which indicates that the alarm condition of the master control parameter is still frequent during the period, and the control module 30 controls to extend the alarm refractory period time of the current or next master control parameter. Therefore, after the time of the alarm refractory period is prolonged, the alarm under the same condition can be reduced, repeated alarm is reduced, and the problem of fatigue of the alarm is reduced. In the present application, the extension of the alarm refractory period may be an extension of the alarm refractory period of one physiological parameter, two physiological parameters or more physiological parameters, which is not limited herein.

The self-adaptive alarm method further comprises the following steps:

and S7, after the number of times of prolonging the alarm refractory period exceeds a preset threshold, setting the prolonged alarm refractory period as a default alarm refractory period. That is, when it is detected that the number of times that the master control parameter exceeds the corresponding normal range but the reference parameter does not exceed the corresponding preset range within the alarm refractory period is greater than the preset number of times and the number of times that the alarm refractory period is prolonged exceeds the preset threshold, the control module 30 automatically sets the prolonged alarm refractory period to be the default alarm refractory period, that is, the effective time of the subsequent alarm refractory period to be the prolonged alarm refractory period. The extended alarm refractory period may be obtained according to the duration of each extended alarm refractory period, for example, an average value of the durations of each extended alarm refractory period, or may be determined according to the duration of the last extended alarm refractory period, which is not limited herein.

Specifically, in an embodiment, when the number of times of the alarm refractory period is prolonged to exceed a preset threshold, a corresponding relation is generated according to the number of times that the master control parameter exceeds the normal range and the reference parameter does not exceed the preset range in the alarm refractory period and the corresponding prolonged time of the alarm refractory period, and the prolonged time of the alarm refractory period is determined according to the number of times that the master control parameter exceeds the normal range and the reference parameter does not exceed the preset range and the corresponding relation in real time. That is, after the control module 30 prolongs the time of the alarm refractory period for a plurality of times, the control module 30 may generate a corresponding relationship according to the specific number of times the physiological parameter detected in a period of time exceeds the normal range and the specific time of the corresponding prolonged alarm refractory period, so that according to the corresponding relationship, and according to the number of times the physiological parameter is monitored in real time in the next time to exceed the normal range, the prolonged time of the alarm refractory period may be determined, thereby adaptively prolonging the time of the alarm refractory period, and the adaptively prolonged alarm time may further avoid the technical problem of alarm fatigue caused by repeated alarms. It will be appreciated that the time of the alarm refractory period may also be adaptively shortened. Therefore, the alarm refractory period duration suitable for the current condition of the monitored object can be formed according to the condition of each monitored object.

Wherein the method further comprises: displaying at least one of the trend graph of the main control parameter, the normal range, the alarm refractory period, the reference parameter or the preset range. The method can also enable a user to intuitively observe the reasons for alarming or not alarming by displaying at least one of the trend chart of the main control parameter, the normal range, the alarm refractory period, the reference parameter or the preset range.

In summary, the self-adaptive alarm method of the invention realizes flexible setting of the alarm refractory period, can not only meet the requirement that the physiological state of the monitored object can be still alarmed even in the refractory period when the physiological state of the monitored object is deteriorated, but also prolong the refractory period length to reduce repeated alarm, and simultaneously can also automatically prolong the refractory period length to reduce repeated alarm.

Referring to fig. 3, the present application further provides an adaptive alarm device, which may be applied to medical devices such as monitors, similar to the adaptive alarm system and method described above.

The self-adaptive alarm device comprises a parameter acquirer, a controller and an alarm, wherein the parameter acquirer is connected with the controller, and the controller is connected with the alarm. The "connection" here may be a direct connection or an indirect connection, may be a wired connection or a communication connection, and a specific connection manner thereof is not limited as long as the connection is directly or indirectly made therebetween.

And the parameter acquirer is used for acquiring the measurement signal. In one embodiment of the present application, a measurement signal is used.

The controller receives and analyzes the measurement signals from the parameter acquirer to acquire a main control parameter and a reference parameter, and when the main control parameter exceeds a normal range, the controller outputs a first alarm instruction aiming at the main control parameter and controls an alarm refractory period for starting the main control parameter; and in the alarm refractory period, when the main control parameter exceeds a normal range and the reference parameter exceeds a preset range, adjusting the duration of the alarm refractory period. And the alarm is used for alarming the main control parameter when receiving the first alarm instruction.

In an embodiment, the controller is further to: outputting a second alarm instruction aiming at the main control parameter when the main control parameter exceeds a normal range and the reference parameter exceeds a preset range in the alarm refractory period; the alarm is also used for alarming the main control parameter when at least one of the first alarm instruction or the second alarm instruction is received.

When the physiological state of the monitored object is normal, the physiological parameter of the monitored object is in a normal range, any alarm condition is not met, and the alarm does not alarm; when the physiological state of the monitored object is abnormal, if the physiological parameter of the monitored object exceeds the normal range, the physiological parameter of the monitored object reaches the original alarm condition, the alarm alarms the physiological parameter, and at the moment, the controller controls the alarm of the main control parameter of the monitored object to enter an alarm refractory period; and in the alarm refractory period, if the main control parameter exceeds the normal range and the reference parameter does not exceed the preset range in the alarm refractory period, the alarm only alarms the main control parameter. And if the main control parameter exceeds the normal range, and the reference parameter exceeds the preset range and does not exceed the normal range of the reference parameter, the alarm only alarms the main control parameter. When the physiological state of the monitored object is deteriorated, that is, the reference parameter of the monitored object exceeds the preset range, the alarm still alarms the main control parameter again even in the alarm refractory period.

Therefore, the self-adaptive alarm system can alarm the physiological parameter even if the physiological parameter of the monitored object exceeds the preset range when the physiological parameter of the monitored object is in the alarm refractory period, so that the physiological state of the monitored object can be timely found to be deteriorated, and the probability of danger of the monitored object is reduced.

In an embodiment, the controller is further configured to determine a number of times that the master control parameter exceeds the normal range and the reference parameter is located in the preset range during the current alarm refractory period, and when the number of times is greater than a preset number of times, extend the time of the alarm refractory period.

In an embodiment, the controller is further configured to set the extended alarm refractory period to a default alarm refractory period after the number of times of extending the alarm refractory period exceeds a preset threshold.

In an embodiment, when the number of times of extending the alarm refractory period exceeds a preset threshold, the controller is further configured to generate a corresponding relationship between the number of times of exceeding the normal range by the master control parameter and not exceeding the preset range by the reference parameter and the corresponding extension time of the alarm refractory period, and determine the extension time of the alarm refractory period according to the number of times of exceeding the normal range by the master control parameter and not exceeding the preset range by the reference parameter and the corresponding relationship in real time.

In an embodiment, the alarm is further configured to alarm at least one physiological parameter when the at least one physiological parameter of the main control parameter or the reference parameter exceeds the corresponding normal range and the current time is outside the alarm refractory period.

In summary, the self-adaptive alarm device of the invention realizes flexible setting of the alarm refractory period, can not only meet the requirement that the physiological state of a monitored object can be still alarmed even in the refractory period when the physiological state of the monitored object is deteriorated, but also prolong the refractory period length to reduce repeated alarm, and simultaneously can also automatically prolong the refractory period length to reduce repeated alarm.
