Sleep respiratory function monitoring system based on infrared radiation detection

Abstract

The invention discloses a sleep respiratory function monitoring system based on infrared radiation detection. The sleep respiratory function monitoring system comprises a planar array infrared non-contact sensor, a multichannel A / D (analog to digital) converter, a data collection processing FPGA (field programmable gate array), a data processing analysis DSP (digital signal processor) and a data communication unit. The invention provides the non-contact infrared sleep respiratory function monitoring system for the first time, the discomfort caused by constraint on leading cadres or special crowds (such as burn patients) by the existing contact type monitoring means is changed, and the remote non-contact monitoring is realized. The remote non-contact respiratory rate and respiratory depth monitoring on special patients who are not suitable for wear a sensor is provided for the first time.

Description

technical field [0001] The invention relates to a sleep breathing function monitoring system based on infrared radiation detection. Background technique [0002] According to statistics, people spend 1 / 3 of their life in sleep. Therefore, healthy sleep is very important to people's health. Various sleep-disordered breathing such as apnea and hypopnea may occur during sleep. [0003] Sleep apnea syndrome (sleep apnea syndrome, SAS) is a complex disease that causes upper airway obstruction due to certain reasons, apnea during sleep, and symptoms such as hypoxia, snoring, and daytime sleepiness. . It not only affects people's sleep quality, but also induces diseases such as high blood pressure and cardiovascular and cerebrovascular diseases. In the crowd, the proportion of suffering from breathing and sleep disorders and secondary chronic diseases is very large. [0004] SAS has a high incidence rate and is extremely harmful. It not only reduces the quality of life, but als...

AI Technical Summary

Problems solved by technology

However, the detection of sleep structure and sleep breathing events in PSG is relatively cumbersome, and the recording of parameters needs to paste and connect up to a dozen electrodes to the patient. Obtaining sleep structure generally requires simultaneous measurement of 5 signals, namely, two channels of EEG and two channels of eye movement. Electrical signal and a mental muscle electrical signal; detection of sleep breathing events requires simultaneous measurement of the patient's oro-nasal airflow, chest respiration, abdominal respiration and blood oxygen and other physiological signals

Therefore, the main disadvantages of PSG are: ①It is very complicated for medical staff to operate; ②The cost of testing that patients need to bear is expensive; ③Contact testing, the patient’s physical and psychological load is relatively large, etc.

However, this method is greatly affected by the movement of the surrounding and human organs, the use environment is strict, and the measurement is inaccurate
