Non-contact sleep monitoring device and monitoring method

Abstract

The invention discloses a non-contact sleep monitoring device and a monitoring method. The non-contact sleep monitoring device comprises a monitoring body, a chip box and a mobile terminal, wherein the monitoring body is sequentially provided with an upper envelope, an upper shielding layer, a PVDF pressure sensor, a lower shielding layer and a lower envelope from top to bottom; and a signal amplification module, a filtering module, an analog-to-digital conversion module, a control module, a WiFi module, a storage module and a timing module are arranged in the chip box. By applying the non-contact sleep monitoring device and the monitoring method, the measurement of respiration and heart rate can be realized, the material is sensitive, and the obtained data is more accurate. Meanwhile, the cost is low, the material is saved, and the installation and application are simple. The non-contact measurement of physiological signals can be realized, no discomfort is caused, the normal sleep of people cannot be interfered, and the monitoring data is more reliable. A user can know the contents such as self sleep time, sleep duration and sleep evaluation according to the sleep monitoring condition and an analysis report. Meanwhile, the self sleep condition can be adjusted according to historical data, so that the analysis reference is more suitable for the self sleep condition.

Description

Technical field [0001] The present invention relates to the field of sleep monitoring, especially in a non-contact sleep monitoring device and a monitoring method based on PVDF piezoelectric film. Background technique [0002] The importance of sleep for health of the person is self-evident, so that people sleep in the brain and body a rest, rest and recovery, as an important part of the body to repair life, sleep and people's physical and mental functions are closely related, and affect people's health, quality of life and work efficiency, and many other aspects. Sleep is good or bad does not depend on the length of time, but on the quality of sleep, sleep, sleep quality monitoring and analysis has become an important part of assessing a person's health status and related diseases prevention. In addition, many internal physiological functions during sleep the body will change significantly during sleep time, continuity and change in body function regulation system, early signs o...

Problems solved by technology

Among them, polysomnography monitors many parameters and uses a variety of sensors. It is necessary to attach multiple electrodes to the human body, which will affect normal sleep. During the monitoring process, patients have hospitalization monitoring, difficulty falling asleep, and sensors are easy to fall off, etc. Shortcomings, the obtained data cannot accurately reflect the normal sleep conditions of the subjects

The connection of mattress sleep monitoring products is complicated, cumbersome, and difficult to realize; the number of sensors is too large, the connection is difficult, the data of multiple signal sensors is separated and independent, the continuity of signal transmission is poor, and the material consumption is high, and the cost is high; in addition, the equipment is bulky and inconvenient Mobile, cumbersome procedures, difficult to use at home

Infrared monitoring equipment is very expensive and can only be used in medical research institutions and is difficult to popularize

Some "weakly invasive" or contact devices, such as smart watches, smart bracelets, wristband measurement, fingertip monitoring of peripheral arteries, etc., will cause discomfort to the tested personnel and affect sleep quality
