Method and system for performing snore recognition and strength output and breathing machine

Abstract

The invention discloses a method and a system for performing snore recognition and strength output and a breathing machine. The system mainly comprises a breathing flow collector, a breathe recognizer, a snore feature recognizer and a snore strength output device which are connected in sequence, wherein the breathing flow collector collects expiration and inspiration flows in the breathing process and sends the flows to the breathe recognizer. The breathe recognizer is used for recognizing an inspiration starting point and an inspiration ending point in a breathing period. When the inspiration starting point is detected, the snore feature recognizer is started, and the snore strength output device is closed. When the inspiration ending point is detected, the snore feature recognizer is closed, and the snore strength output device is started. The snore feature recognizer analyzes flowing speed change characteristics in an inspiration period and recognizes whether snoring occurs or not. The snore strength output device judges recognized snore and then outputs normalized snore strength indexes. By adopting the method and the system for performing the snore recognition and the strength output, the success rate of accurate judgment is improved, the hardware cost is saved, and the achieving complexity is reduced.

Description

technical field [0001] The invention relates to an identification and evaluation method, in particular to a method and system for identifying and outputting the intensity of snoring and a ventilator. Background technique [0002] When a person sleeps, the pillow is too high or too low or the throat cavity is compressed, which will block the airflow in and out and easily cause snoring; And any factor that can cause narrowing of the airways in the nose, throat, etc. will promote snoring. Excessive fat deposition in the neck of obese patients is also one of the reasons for snoring due to narrowing of the airway. There are also some patients with no abnormal airway during the day, but the muscle tension around the airway is reduced during sleep, and the base of the tongue falls back when sleeping in the supine position, which can also cause narrowing of the airway and affect the smooth passage of airflow. [0003] Clinically, sleep apnea syndrome revealed a close relationship ...
