Device for detecting obstructive respiration disorder and test method of device

Abstract

The invention discloses a device for detecting obstructive respiration disorder. The device comprises an acceleration sensor, an analog signal pre-processing circuit, an A/D converter, a skin resistance sensor and a single chip, wherein the analog signal pre-processing circuit comprises an analog signal amplifying circuit and an analog signal filter circuit; the acceleration sensor is used for acquiring a respiratory movement analog signal of a human body chest/abdomen part under a sleep status; the skin resistance sensor is used for acquiring a skin resistance signal of the chest/abdomen part; the A/D converter is used for converting the respiratory movement analog signal, which is processed by virtue of the analog signal pre-processing circuit, into a digital signal; the single chip is used for conducting obstructive respiration disorder judgment in accordance with the skin resistance signal and the digital signal; and the single chip is connected to the A/D converter and the skin resistance sensor. The invention also discloses a testing method based on the device for detecting the obstructive respiration disorder. According to the device and the testing method provided by the invention, under the precondition of guaranteeing detection accuracy, cost is also reduced.

Description

technical field [0001] The invention belongs to the technical field of sleep breathing monitoring, and in particular relates to a device for detecting obstructive breathing disorder and a testing method thereof. Background technique [0002] Sleep apnea includes normal sleep apnea and sleep apnea. Common sleep-disordered breathing states include snoring and apnea. Sleep apnea refers to a sleep disorder in which breathing stops during sleep. There are three main types of sleep apnea: obstructive sleep apnea, which is caused by the relaxation of soft tissues near the throat during sleep, resulting in narrowing or even obstruction of the upper airway, resulting in apnea; central sleep apnea, which is related to the central nervous system that controls breathing. Dysregulation, temporary loss of the central nervous drive of respiratory function, this breathing disorder is not caused by airway obstruction; and a mixture of the above two. According to statistics, the number of ...

Problems solved by technology

However, with the method of two-way breathing belt, the user will feel tight during the breathing process, and it is uncomfortable to wear; the two-way body surface resistance method proposed later for comfort is easy to wear and has high accuracy, but the application is complicated and the cost is high.
