Intelligent sensing mattress for monitoring sleep

Abstract

The invention belongs to the technical field of sleep monitoring, and particularly relates to an intelligent sensing mattress for monitoring sleep. Two kinds of flexible pressure sensors are adopted, wherein the first kind of the pressure sensors are used for producing pressure sensing arrays, are uniformly distributed in the whole mattress, and are used for detecting stressing conditions in the most part of the mattress, the second kind of sensors are distributed in several key positions of the mattress, and are used for collecting signals which can cause pressure change like respiration signals, body movement signals, and heart rhythm signals of a user, and transferring the pressure changing signals into electric signals; follow-up hardware conducts amplification, smoothing and transmission on the obtained electric signals, then conducts feature extraction and pattern recognition processing on the signals through a PC end to obtain a pressure distribution image and sleep analysis. According to the intelligent sensing mattress for monitoring sleep, ultra-thin flexible materials are used in sensors and structures thereof like electrodes, thus the mattress is small in thickness, light in weight, and convenient to carry; due to the fact that the intelligent sensing mattress for monitoring sleep is run in a non-intrusive mode, sleep monitoring can be conducted under the condition that a user is unconscious, thus the natural sleep of the user can be fully restored, and thus powerful supplement is made for family-type nursing.

Description

technical field [0001] The invention belongs to the technical field of sleep monitoring, and in particular relates to a non-invasive sleep monitoring device. Background technique [0002] At present, the gold standard for clinical sleep monitoring of patients is polysomnography monitoring technology, but the structure of polysomnography monitoring technology is complex and inconvenient to operate, which causes a certain psychological burden on patients and seriously affects their normal sleep. Therefore, sleep monitoring is developing in a non-invasive direction, and strives to restore natural sleep to the greatest extent. In current clinical practice, whole-night polysomnography (PSG) is the gold standard for sleep monitoring. PSG measurements are usually only available in hospital sleep laboratories. PSG includes multiple physiological signals such as ECG, EEG, EMG, eye movement tracking, and blood oxygen saturation. The system uses many gel electrodes and bulky equipme...

Problems solved by technology

However, these systems often only measure some of the parameters required for sleep analysis, and do not provide a comprehensive data measurement plan to meet the clinical diagnosis of sleep disorders

Moreover, there are still some technical difficulties in the above-mentioned various new technologies, such as: reliable and stable acquisition of standard ECG and respiratory signals, how to
