Embodiment 1

[0032] The user sets the high alarm limit and low alarm limit according to the actual situation or experience, detects the rhythmic physiological parameters of the human body through the detection unit of the equipment, and compares the measured value of the human rhythmic physiological parameters with the high alarm limit and the low alarm limit. When the measured value of the rhythmic physiological parameters of the human body is greater than the high alarm limit or less than the low alarm limit, it is abnormal. In order to reduce false alarms when the rhythmic physiological parameters of the human body are abnormal, the scheme of this embodiment is as follows: figure 1 As shown, it includes a calculation unit and an alarm trigger unit, and the calculation unit is used to calculate the product and integral of the relevant amount of the abnormal rhythmic physiological parameter and the abnormal state maintenance time when the human rhythmic physiological parameter detected by ...

Embodiment 2

[0046] Compared with Embodiment 1, this embodiment adds another alarm condition on the basis of taking the product or integral of the relevant amount of abnormal rhythmic physiological parameters and the abnormal state retention time as an alarm condition to trigger the alarm, that is, the need The conditions for alarm generation are met. Such as Figure 4 As shown, the alarm triggering unit includes a first judging module, a second judging module, an alarm delay time acquisition unit and a processing module, and the first judging module is used to combine at least one of the product and the integral with the corresponding setting Thresholds are compared to determine whether the set threshold is exceeded; the second judging module is used to judge whether the abnormal duration of the rhythmic physiological parameters meets the alarm generation condition; the processing module is used in the product and integral An alarm is triggered when at least one of them exceeds a corresp...

Abstract

The invention discloses an alarm triggering method based on a human body rhythmic physiological parameter and a device thereof. The method comprises the following steps: A1, when the human body rhythmic physiological parameter exceeds the alarm limit, either the product of or the integral of the correlative quantity of the abnormal rhythmic physiological parameter and the continuous retention time of the abnormality are calculated; and B1, the calculation result in step A1 is used as the condition for triggering the alarm and whether the alarm is triggered or not is determined. The invention uses the combination of the value or the excess of the rhythmic physiological parameter exceeding the alarm limit and the retention time of the abnormal state as the condition or one of the conditions for triggering the alarm, which is in conformity with the human body physiological parameter, thereby reducing false alarms, improving the safety and reliability of monitoring devices, and reducing interference on medical personnel.

Description

【Technical field】 [0001] The invention relates to an alarm method and an alarm device, in particular to an alarm trigger method and an alarm trigger device for alarming based on human rhythmic physiological parameters. 【Background technique】 [0002] There are many physiological rhythmic changes in the human body during life activities, such as: breathing frequency, heartbeat speed, pulse fluctuations per minute, etc. In modern medicine, these rhythmic parameters are important for clinical Observation and diagnosis are of great significance. Doctors often diagnose patients by detecting changes in these rhythmic physiological parameters. in an emergency. [0003] Rhythmicity is a monitoring parameter of common concern in many fields of monitoring human physiological functions. The so-called rhythmicity refers to the working frequency of a certain human organ or a certain circulatory system of the human body (such as: breathing, heartbeat, pulse, etc.), which means that the ...
