Problems solved by technology

With the rapid development of the respiratory products industry, the therapeutic performance of different oxygen savers cannot be achieved without the guidance of clinicians
[0010] The above-mentioned current oxygen saver application market has different oxygen saver settings. When the oxygen saver settings are the same, the oxygen supply capacity is different and the clinical effectiveness is different. Some manufacturers ignore the curative effect and only focus on oxygen saving. These problems make it difficult for medical personnel to accept oxygen saving in application. The user cannot get effective treatment, which hinders the wide application of oxygen saver and wastes precious oxygen resources

Abstract

The invention discloses a method for controlling oxygen delivery. The method comprises the following steps: setting a first oxygen supply flow model; detecting air pressure in the oxygen conveying device; judging whether the user is in an inspiration state or not according to the air pressure value and the air pressure change degree in the air conveying device; if the user is judged to be in the inspiration state, according to a first oxygen supply flow model, controlling an oxygen conveying pipeline of the oxygen conveying device to be opened so that oxygen can be provided for the user through the oxygen conveying device, closing the oxygen conveying pipeline of the oxygen conveying device when the opening time of the oxygen conveying pipeline of the oxygen conveying device reaches the set first time, wherein the first time is shorter than the time when the user is in the inspiration state. According to the method, an oxygen source is saved, the outdoor portable oxygen supply time ofa user is prolonged, and the life quality of the user is improved.

Description

technical field [0001] The invention relates to the technical field of oxygen economizers, in particular to a method for controlling oxygen delivery. Background technique [0002] Traditional oxygen therapy is a low-flow continuous flow through the nose, see Figure 9 , although this is a relatively simple treatment modality, a large amount of oxygen is wasted during the patient's exhalation phase. In addition, a large amount of oxygen is also wasted during the late inspiratory phase because the inhaled oxygen does not reach the gas exchange sites in the lungs during this period. Therefore, combining a range of oxygen sources, including liquid oxygen, cylinder gas oxygen, and battery-powered oxygen machines, with a variety of oxygen economizers results in an ideal oxygen-sparing oxygen therapy regimen. These devices are called pulse oxygen systems. Numerous studies and clinical trials have shown that pulse oxygen devices are highly effective in therapy across a range of br...
