Breathing machine regulation and control method and system based on sleep characteristics

Abstract

The invention discloses a breathing machine regulation and control method and system based on sleep characteristics. The method comprises the steps that S1, the sleep posture of a user is obtained; S2, whether each airway of a pre-worn multi-channel breathing mask is suspected to be pressed or not is judged based on the sleep posture of the user, and a certain electric control valve preassembled in the airway is controlled to open the airway which is not suspected to be pressed; the breathing mask is provided with a plurality of airways communicated with the breathing machine, at least two airways are located on the two sides of the face, and at least one airway extends out of the head top and the airways are provided with corresponding electric control valves for controlling on-off; S3, respirator parameters are obtained; S4, on the basis of the parameters of the breathing machine, the variable quantity of pressure and / or flow before and after airway switching of the breathing mask is calculated; and S5, whether the variable quantity is larger than a threshold value or not is judged, if yes, the data in the stage are marked as sleep posture interference data, a breathing machine parameter adjusting logic starting point updating instruction is sent, and the starting point is t1 time after airway switching. The method has the effect of improving the regulation and control accuracy of the breathing machine.

Description

technical field [0001] The present application relates to the field of ventilator technology, in particular to a method and system for regulating a ventilator based on sleep characteristics. Background technique [0002] Sleep apnea-hypopnea syndrome is the narrowing or collapse of the upper airway when a person is sleeping, leading to snoring and apnea during nighttime sleep. Sleep apnea causes recurrent nocturnal hypoxia, which can easily lead to complications such as hypertension, coronary heart disease, diabetes and cerebrovascular disease, traffic accidents, and even sudden death at night. [0003] At present, ventilators are no longer limited to post-traumatic breathing assistance, but are also used to treat the above-mentioned respiratory diseases. [0004] The patent with application number CN201610861972.9 discloses a ventilator adjustment method based on breathing and sleep events and the ventilator. The adjustment method of the ventilator based on breathing and s...

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor believes that it has the following defects: the airway flow and pressure are determined based on the above-mentioned sleep event, and in the sleep state, besides the symptoms of the user's respiratory tract, there are also sleep postures that affect the two parameters, which lead to the impact on breathing. machine control accuracy, so this application proposes a new technical solution
