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
The invention belongs to sleep monitor technical field, and in particular to a kind of non-intrusion type sleep monitoring device.
Background technology
The goldstandard for clinically carrying out sleep monitor to patient at present is Polysomnography technology, but polysomnogram
Monitoring technology complex structure, operation inconvenience, using when certain psychological burden is caused to patient, have a strong impact on its ortho sleep.
Therefore sleep monitor develops towards the direction of non-intrusion type, makes every effort to farthest reduction naturally sleep.In current clinic
In practice, full night polysomnogram（PSG）It is the goldstandard of sleep monitor.PSG measurements are typically only capable to the sleep experiments in hospital
Carry out room.PSG includes multi-channal physiological, such as electrocardiogram, electroencephalogram, electromyogram, ocular movement tracking and blood oxygen saturation
Degree.The system is directly connected to using the equipment of many gel electrode and heaviness by numerous wires and human body, and this is to natural
Sleep mode forms very big interference, uncomfortable, inconvenience, therefore user's acceptance is very low.For example, when client need goes lavatory,
He or she must one by one remove the sensor of all connections, after returning, then they are reconnected, is started, and this is a phase
When complicated process.The interference to natural sleep is additionally, since, the measurement of PSG can not completely represent real sleep state, because
This has error based on its diagnosis and treatment.
The sensitive mattress that non-intrusion type sleep monitor can be carried out on the market at present mainly uses Embedded pressure biography
Sensor, the pressure signal of user body is detected by being embedded in the sensor inside mattress, and is carried out according to pressure signal
Body it is dynamic should, from bed sensing, respiration detection and heart rate detection, above-mentioned physiological signal is analyzed into process, obtain user
Sleep quality.There is article to show that the device for generating human pressure's distributed image can make the form of mattress simultaneously, but city
Sensitive mattress on face cannot generate pressure distribution image, it is impossible to obtain the position that the sleep attitude of user is concentrated with pressure,
Simultaneously generation pressure distribution image resolution is relatively low in document, in the middle part of the attitude for finding out sleep quality that can only be rough and pressure collection
Point；And embedded sensor distribution is more concentrated, the quality of analysis result depends on the relative position of sensor and user,
Therefore the installation of mattress and use needs the guidance of professional.In recent years, for " weak intrusive mood " or portable sleep monitor
Systematic research achievement has had much to be reported, for example：Intelligent bed pads existing heart alluviation figure（BCG）Monitoring ［ 1 ］；Application of force is quick
Type weaving cloth makes array of pressure sensors and is implanted in sheet realizes that human body attitude changes and monitoring of respiration；Intelligent watch or
Wrist strap measurement PPG signals ［ 2 ］；In fingertip monitor peripheral arterial sound ［ 3 ］；By realizing sleep to the analysis of cardiopulmonary activity record data
Analytic hierarchy process and classification ［ 4 ］；The asphyxia ［ 5 ］ occurred in sleep procedure is detected using forehead near infrared technology；Semen setariae,
The wearable device that the enterprises such as Actiwatch, Fitbit release realizes dynamic record ［ 6,7 ］ of body etc. in sleep procedure.But, this
A little systems often simply measure the partial parameters needed for sleep analysis, are not given and meet needed for sleeping disorders clinical diagnosises
Comprehensive data measurement scheme.And, still suffer from some technological difficulties in above-mentioned various new techniques and do not solve, for example：The standard heart
The reliable and stable collection of electricity and breath signal, how under motion artifacts interference to improve the robustness of detection, how to eliminate sleep
The different errors for introducing of attitude.At present, still not studying can realize that the system that this project is intended researching and developing is " completely non-to daily sleep
Intrusive mood ", " suitable comfortable sleeping ", and realize the high reliability and stability of signals collecting.
