System for presuming sleep indexes and sleep stages by method for measuring physiological parameters in unconstrained manner

Abstract

The invention discloses a system for presuming sleep indexes and sleep stages by a method for measuring physiological parameters in an unconstrained manner. The system has the advantages that a unique technology for eliminating external interference signals transmitted from a floor to a bed is adopted to improve the measurement precision of the detecting system; physiological signals of a human body are acquired by a senor, and data are processed by a comb filter, so that signal waveforms of heart rate numbers, breathing numbers and the turnover frequency of the human body can be acquired, the data of the sleep stages can be continuously extracted, and a sleep status of the human body can be presumed according to high-precision pulse and body movement data; and a sleep stage classification technology and a unique sleep presumption technology are adopted for a sleep stage algorithm for speculating the depth of sleep, so that the sleep stage presumption accuracy is improved, and the measuring system can precisely detect the sleep indexes.

Description

technical field [0001] The invention relates to a physiological detection signal detection device and a sleep measurement system for performing statistical processing on the detection signal and estimating sleep state according to the extracted physiological signal. Background technique [0002] Sleep plays an important role in recovering mental and physical strength from fatigue, and by ensuring high-quality sleep, it can promote the maintenance and strengthening of health. [0003] For the technique of measuring the pulse without restraint and without contact for sleep quality measurement, paper publications and Japanese patent applications have been made by the present inventors. For example, a sleep depth determination method and determination device have been proposed, which detect physiological information of the human body by using an air cushion filled with air, and can determine the change of the sleep stage of the test subject, or calculate the time of each sleep s...

Problems solved by technology

[0008] However, it has not been put into practical use due to the large size of the device and the very high cost.

In addition, it is difficult to function as a system that can effectively prevent the transmission of bed vibration in the currently used small rubber rollers that are directly installed on the pillars and have the anti-skid cushioning effect of rubber materials.

It is necessary to develop low-cost and achieve the
