Abstract

The invention relates to a method for self-adaptive alignment calibration of an IP valve of an anaesthesia machine. The method comprises the following steps: determining zero opening voltage of the IP valve; taking the zero opening voltage as the initial value of the IP valve, gradually increasing the voltage value of the IP valve and recording voltage value of the IP valve and corresponding air passage pressure value in a real-time manner; calculating the law of the air passage pressure value and the voltage value of the IP valve by taking voltage valve of the IP valve and the air passage pressure value as the foundation, thereby obtaining alignment calibration data of the IP valve. The method for self-adaptive alignment calibration of the IP valve of the anaesthesia machine has the following beneficial effects: uncertainties of verification of the IP valve are avoided so that accuracy degree of detection is increased; automated degree of verification is increased; the method is applied to multiple anaesthesia machines in clinical practice; and the verification result is accurate and reliable so that good effect is achieved.

Description

technical field

[0001] The invention relates to the field of anesthesia machines, in particular to a method for self-adaptive calibration of IP valves of anesthesia machines. Background technique

[0002] The IP valve is the key component for pressure control and limit protection of the anesthesia machine. During the machine-controlled ventilation process of the anesthesia machine, a certain control voltage is given to the IP valve during the inhalation phase, which can close the IP valve so that the airway can maintain a certain pressure. During the exhalation phase, the exhalation valve is powered off, that is, the IP valve is opened to release the gas to reduce the airway pressure. Therefore, the performance of the IP valve will directly affect the breathing process of the anesthesia machine. Effective detection and calibration of the IP valve is an important guarantee for the normal operation of the IP valve.

[0003] At present, the method of detecting and verifying th...
