Detection method and detection device for anesthesia machine controlled leakage and compliance test pipelines

Abstract

A detection method for pipelines in machine-controlled leakage and compliance tests of an anesthetic machine, comprising the following steps: step S10, entering a machine control leakage test and compliance test state of an anesthetic machine; step S20, the anesthetic machine piping air in an air passage outside a folding bag (6) according to a preset flow rate, and a control unit also controlling and detecting a pressure value in the air passage and the air piping time at the same time; step S30, the control unit acquiring the pressure value in the air passage and the air piping time, and a judgment unit judging whether a condition for the anesthetic machine to stop piping air is achieved or not according to the pressure value in the air passage and the air piping time; step S40, according to the pressure value in the air passage and the air piping time, obtaining a pressure change rate in the air passage in the whole air piping process; and step S50, according to the pressure change rate, judging whether pipelines in leakage and compliance tests are correctly connected or not. Whether pipelines in leakage and compliance tests are correctly connected or not can be learned with the method, thereby avoiding test errors resulting from pipeline connections. Also provided is a detection device for achieving the detection method.

Description

technical field [0001] The invention relates to the field of anesthesia machines, in particular to a method for judging whether pipeline connections are correct in machine-controlled leakage and compliance testing of anesthesia machines, and a detection device for realizing the method. Background technique [0002] In a closed anesthesia machine, the leakage and compliance of the anesthesia machine need to be measured during the power-on self-test, so as to compensate during the machine-controlled ventilation process, that is, to measure the leakage and compliance of the anesthesia machine and the pipeline. However, when testing the leakage and compliance of the anesthesia machine, it is necessary to connect the end of the inhalation and exhalation pipeline of the anesthesia machine to the test head of the anesthesia machine through a Y-shaped tee. The end of the tubing is suspended or connected to a manual bladder, which may cause the tubing to not be connected or connected...

Problems solved by technology

However, when testing the leakage and compliance of the anesthesia machine, it is necessary to connect the end of the inhalation and exhalation pipeline of the anesthesia machine to the test head of the anesthesia machine through a Y-shaped tee. The pipe end is suspended or connected to the manual bladder, which may cause the pipe to not connect or connect incorrectly during the leak test and compliance test, resulting in test errors

[0003] Based on the above description, it is urgent to find a method for judging whether the pipeline connection is correct in the leakage and compliance test of the anesthesia machine. Using this method, it can be accurately known whether the pipeline connection is correct in the leakage and compliance test, so as to avoid Test errors due to tubing connections
