Embodiment 1

[0046] figure 1 It is a structural schematic diagram of the nursing monitoring device of the first embodiment.

[0047] Such as figure 1As shown, the nursing monitoring device includes: a monitoring terminal 1 , a cloud server 4 and an alarm device terminal 5 . The monitoring terminal 1 includes: a real-time display screen 101 , a call button 102 , a wire 103 and a sensor 104 . The monitoring terminal 1 is connected to the sensor 104 through a wire 103 , and a real-time display screen 101 and a call button 102 are set on the monitoring terminal 1 . The alarm device 5 can directly adopt a smart phone, and no additional configuration is required.

[0048] In this embodiment, the sensor 104 is placed above the mattress 2 and below the chest cavity of the care receiver 3 . When the care receiver 3 triggers the call button 102 , the monitoring terminal 1 transmits a signal to the cloud server 4 , and the cloud server 4 controls the alarm device 5 to send an alarm message 501 af...

Abstract

The invention provides a method for monitoring the heart rate and the heart rate variability. The method includes the following steps of obtaining heartbeat signals with the frequency range of 10-80 Hz through a sensor, calculating the power of the obtained heartbeat signals, conducting at least one time of filtering on the power-calculated signals, and conducting peak point recognition on the filtered signals, wherein the peak points are heartbeat moment points. The method has the advantages that the human body heartbeat signals are extracted through the sensor, heart sound frequency band signals of the heartbeat signals are extracted, the more accurate and reliable heartbeat moment points are obtained, and therefore the heart rate and the heart rate variability are calculated.

Description

technical field [0001] The invention relates to a nursing monitoring device for monitoring heart rate and heart rate variability. Background technique [0002] Heart rate and heart rate variability are key indicators for assessing human health. The heart rate variability analysis can help evaluate the human sleep and stress status. However, medical methods and devices for detecting heart rate and heart rate variability based on electrocardiogram (ECG) and photoplethysmography (PPG) all need to be worn by the human body and are relatively cumbersome to use. [0003] A more convenient and wear-free method for monitoring heart rate and heart rate variability based on ballistocardiography (BCG) was proposed and developed. Detects the mechanical shock force signal generated by the heartbeat in the ballistocardiogram (BCG). When the posture of the human body changes, the main peak signal of the heartbeat impact force signal in BCG changes or even weakens. The algorithm using pe...
