Abstract

The invention provides a self-checking method and device for the flow rate triggering of a respirator. The method comprises the following steps of: a, selecting a plurality of flow rates serving as detection points according to the flow rate triggering range of the respirator; b, controlling a gas flow rate output by the respirator to each detection point and detecting the detection points in sequence; and c, comparing the flow rate of each detected detection point with a corresponding preset detection index to obtain a self-checking result of the flow rate triggering of the respirator. The device comprises a selecting module, a detecting module and a comparing module, wherein the selecting module is used for selecting detection points according to the flow rate triggering range of the respirator; the detecting module is used for detecting the detection points in sequence; and the comparing module is used for comparing the flow rate of each detection point and a preset detection index. Compared with the prior art, the invention has the advantages that: detection of flow rate triggering accuracy is realized and is completed together with startup self-checking, detection of the flow rate triggering accuracy of the respirator can be realized without any tool during delivery inspection, the cost is saved, and the reliability of the respirator is enhanced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a self-checking method and device for triggering the flow rate of a ventilator. Background technique [0002] In order to ensure that the ventilator can work normally, a self-test is generally required when the ventilator is turned on. Different ventilators have different self-test contents, mainly including flow sensor test, pressure sensor test, pipeline air tightness test, pipeline resistance test, pipeline compliance test and so on. Only when the self-test passes, the ventilator can be used normally. If there is an alarm or failure prompt, it is necessary to check the ventilator or the pipeline, and notify a professional engineer for maintenance if necessary. Ventilators generally have two trigger modes: pressure trigger and flow rate trigger. The flow rate triggering method relies on the flow sensitivity to realize the user's triggering of instructions or spontaneous breathi...
