Abstract

The invention provides an air leakage quantity obtaining method of a positive pressure breathing device. The method comprises the following steps that: firstly, a pressure and flow rate conversion formula is built, then, the pressure data measured by a pressure meter of the positive pressure breathing device is converted into flow rate data through the pressure and flow rate conversion formula, and next, the difference between the flow rate data and the standard flow rate is calculated to obtain the air leakage quantity. The air leakage quantity obtaining method has the advantage that the cost of the positive pressure breathing device can be reduced. In addition, the invention also provides the positive pressure breathing device capable of converting the pressure data into the flow rate data.

Description

technical field [0001] The present invention relates to a breathing device, and in particular to a positive pressure breathing device and a method for obtaining air leakage. Background technique [0002] The progress and development of medical equipment not only helps medical research and disease diagnosis, but also helps improve the quality of life of patients. Among them, for patients with obstructive sleep apnea, positive pressure breathing devices can help improve their sleep quality. Moreover, its use records can also provide the basis for diagnosis and treatment by medical personnel. [0003] Existing positive pressure breathing devices supply air to the user via a mask. After the patient falls asleep, the mask may be loosened due to a change in the sleeping position, thereby causing gas to leak outward. In this way, in addition to reducing the use efficacy of the positive pressure breathing device, the credibility of the relevant use data recorded by it will be gre...
