Detection method and detection device for pipelines in machine-controlled leakage and compliance tests of anesthetic machine

A detection method for a pipeline in machine-controlled leakage and compliance tests of an anesthetic machine, comprising:

• Step S10:
• entering a state of machine-controlled leakage and compliance tests of an anesthetic machine;
• Step S20:
• controlling, by a control unit, the anesthetic machine to input a gas into an external gas passage of a folding bag at a preset flow rate, controlling a pressure sensor to detect the pressure in the gas passage, and controlling timing means to detect a gas inputting duration;
• Step S30:
• acquiring, by the control unit, the pressure in the gas passage and the gas inputting duration, and judging, by a judgment unit, whether the pressure in the gas passage reaches a preset pressure threshold and whether the gas inputting duration reaches a preset gas inputting duration threshold;
• and if either of the preset pressure threshold and the preset gas inputting duration threshold is reached, the control unit controlling the anesthetic machine to stop the gas inputting;
• Step S40:
• obtaining, by a computing unit, a pressure change rate of the gas passage during the whole gas inputting process according to the pressure in the gas passage and the gas inputting duration detected in Step S20;
• and
• Step S50:
• judging, by the judgment unit, whether the pipeline in the machine-controlled leakage and compliance tests of the anesthetic machine is connected correctly according to the pressure change rate.
