Abstract

A method and a device for calibrating PEEP valve are provided. The calibrating method comprises: obtaining a function between a control voltage value of the PEEP valve and a gas conduit pressure value of a breathing loop system, according to a plurality of groups of different control voltage values of the PEEP valve and the gas conduit pressure values of the breathing loop system corresponding to the control voltage values; adjusting the control voltage value of the PEEP valve according to the function in order to obtain an expected gas conduit pressure of the breathing loop system. By establishing a segmented linear plot of the function corresponding to the relationship between the control voltage and the gas conduit pressure values, the method and the device can adjust the control voltage of the PEEP valve according to the segmented linear plot of the function, thereby achieving precise control of the PEEP valve.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a calibration method and device for a PEEP (Positive End-Expiratory Pressure, positive end-expiratory pressure) valve. Background technique [0002] The traditional PEEP valve calibration method is complicated and requires professional tooling and equipment, and this calibration method is only applicable to the production process, not to the user's site. When the anesthesia machine or ventilator deviates due to wear or other reasons at the user's site, there is no suitable way to re-calibrate the PEEP valve, so precise control of the PEEP valve cannot be realized. Contents of the invention [0003] The main purpose of the present invention is to provide a calibration method and device for a PEEP valve, to at least solve the above-mentioned problem that there is no suitable way to re-calibrate the PEEP valve in the field of use, so the precise control of the PEEP valve cannot be...
