Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] figure 1 A flowchart showing a method for adjusting the output pressure of a ventilator decompression device according to an embodiment of the present invention, including the following steps:

[0022] Step S10, setting the target value of the output pressure of the decompression device of the ventilator;

[0023] Step S20, taking the difference between the target value of the output pressure and the measured actual value of the output pressure as the pressure deviation value;

[0024] Step S30, adjusting the output pressure according to the pressure deviation value.

[0025] This embodiment uses the deviation between the output pressure target value and the actual value of the ventilator decompression device to adjust the output pressure, which solves the problem that the output pressure of the existing ventilator decompres...

Abstract

The invention provides a method for regulating the output pressure of a respirator decompressor, comprising the following steps of: setting the target value of the output pressure of the respirator decompressor; taking the difference of the target value and the measured practical value of the output pressure as a pressure bias value; and regulating output voltage according to the pressure bias value. The invention also provides a device for regulating the output pressure of the respirator decompressor, comprising a setting module, a calculation module and a regulation module, wherein the setting module is used for setting the target value of the output pressure of the respirator decompressor; the calculation module is used for taking the difference of the target value and the measured practical value of the output pressure as the pressure bias value; and the regulation module is used for regulating the output pressure according to the pressure bias value. The output pressure of the respirator decompressor can be regulated within certain range by the invention so as to satisfy the requirements of different applications.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method and a device for adjusting the output pressure of a ventilator decompression device. Background technique [0002] In the design of pneumatic and electronically controlled ventilators, it is often necessary to use a pressure reducing valve to provide stable working pressure, and the air circuit control system can achieve more accurate flow control based on this pressure. [0003] At present, the more common pressure control scheme is to use a pre-adjusted mechanical (manually adjusted) pressure reducing valve to output a fixed pressure. The adjustment process requires the use of special equipment. Once set, the output pressure cannot be changed in theory. Since the air flow FLOW controlled by the ventilator=pressure P / adjustable resistance R, when the output pressure P of the pressure reducing valve is constant, the adjustment range of the air flow FLOW is determined by ...
