Sleep breath monitor

Abstract

The invention discloses a sleep breath monitor, which comprises a breath vibration signal receiving device, an IV conversion circuit, an IV amplification circuit, an ARDUINO open source electronic prototype platform, a TF card reader, an LED lamp and a computer, wherein the breath vibration signal receiving device comprises a detection rod, a laser light source, a reflection film, a silicon photodiode, an installation platform and a vibration plate; after laser emitted from the laser light source is reflected by the reflection film, the laser is received by the silicon photodiode, and the silicon photodiode outputs a weak current signal to the IV conversion circuit; after the weak current signal is converted into a voltage signal, the voltage signal is input into an IV amplification circuit to be amplified into an analog signal, and the analog signal is input into the electronic prototype platform; and the TF card reader, the LED lamp and the computer are connected with the electronicprototype platform. The sleep breath monitor can obtain tiny vibration information which can not be identified by the human eyes, through signal processing, breath situation information in sleep is obtained, and the sleep breath monitor can be used for broad sleep-disordered breathing patients to carry out home self monitoring, and assists the patients in knowing the own breath situation.

Description

technical field [0001] The invention belongs to the technical field of monitoring, and in particular relates to a sleep breathing monitor. Background technique [0002] As a basic physiological function of human beings, respiration is the way for the human body to exchange gas with the outside world, and is closely related to human health, but the harsh environment has caused great harm to human health. PM2.5, for example, is an invisible killer of human health. "The Harm of PM2.5 and the Spatial Change of its Concentration" (see: Du Weixin. The Harm of PM2.5 and the Spatial Change of its Concentration [J]. Environment and Development, 2018, 24(06): 178-179. ) pointed out that PM2.5 can be deposited in the bronchi and even alveoli through breathing, and it carries a large amount of pollutants, which will cause extremely serious harm to human health. Especially in smog days, people will inhale certain floating pollutants, and these pollutants will lead to the production of ...

Problems solved by technology

At present, the relatively common detection methods are ultra-wideband bio-radar respiratory monitoring (see: Hang Jinguo, Zhang Yan, Sun Ying, Guan Minchang. Application of ultra-wideband bio-radar technology in the diagnosis of obstructive sleep apnea-hypopnea syndrome in children[J] .Modern Practical Medicine, 2020, 17(02): 192-193.), micro-motion sensitive mattress monitoring (see: Li Weimin; Wang Rongguang; Huang Dongyan; Liu Xiaoli; Jin Wei; Yang Shiming. Micro-motion sensitive mattress sleep Diagnostic value of monitoring system (RS611) for obstructive sleep apnea hypopnea syndrome [J]. Chinese Gerontological Impurities, 2015, 35(05): 1160-1162.) and other respiratory detection methods, but these monitoring methods are subject to many Limitations, such as micro-motion-sensitive mattress-type monitoring, require patients to be monitored in specialized hospital wards, which is very inconvenient for the diagnosis of common diseases

Moreover, the cost of these monitoring methods is high, and some of them also have certain risks.
