Physiological parameter detecting system with comb filter and monitoring system for depth of sleep

Abstract

The invention discloses a physiological parameter monitoring system with a comb filter and a monitoring system for the depth of sleep. External interference signals which are transmitted onto a bed from a floor are eliminated by a unique technology so as to improve the measurement precision of the detecting system. A sensor acquires physiological signals of a human body, and data are processed by the 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 sleep stages are continuously extracted, and a sleep status is presumed according to high-precision pulse and body movement data. In addition, a sleep stage classification technology and a unique sleep presumption technology are adopted for a sleep stage algorithm for speculating the depth of the sleep, so that the sleep stage presumption accuracy is improved, and the measuring system can precisely detect 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 purpose of preventing floor vibration from being transmitted to the device. Although it does not have the effect of forcibly suppressing the vibration generated from the device itself like the above-mentioned measuring device, it can prevent floor vibration from being transmitted to the main body of the bed and make the measurement Anti-vibration system that effectively attenuates the vibration generated by the device itself
