Abstract

The invention provides a method, device and system for controlling the output air amount of an oxygen therapy instrument, and relates to the technical field of oxygen therapy instrument control. The method comprises the steps that data in an air channel is acquired when the oxygen therapy instrument works; a first data waveform is established on the basis of pressure data in the air channel and flow data in the air channel; the first data waveform is processed to obtain a first pressure data set and a first flow data set; on the basis of the first pressure data set and the first flow data set,the output air amount of the oxygen therapy instrument is adjusted. The method solves the technical problem that output air flow of a fan of a traditional oxygen therapy instrument is constant, in the expiration process of a user, the air flow direction of expiration is opposite to the direction of the output flow of the fan, and accordingly expiration of the user is not smooth is solved, and hasthe advantages that the expiration action of the user is judged, the output air amount of the fan is adjusted according to the expiration action of the user, and the user expires smoothly.

Description

technical field [0001] The invention relates to the technical field of control of an oxygen therapy device, in particular to a method, device and system for controlling the output gas volume of an oxygen therapy device. Background technique [0002] In the prior art, the output air volume of the oxygen therapy device is constant, no matter whether the user is inhaling or exhaling, the output air volume of the fan remains unchanged, but the user may have man-machine confrontation when exhaling. Because when the user actively exhales, because the direction of the airflow during exhalation is opposite to the direction of the output airflow of the fan, there will be a confrontation between the two airflows, resulting in a rapid rise in the air pressure in the airway, and the user feels that the exhalation is not smooth And other issues. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] In view of this, the object...
