Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] figure 1 A flow chart of the oxygen mixing method according to the first embodiment of the present invention is shown, the method includes the following steps:

[0020] Step 101, calculating the target oxygen supply according to the current operating parameters of the electric ventilator, the initial operating parameters at the start of inhalation, and the preset target oxygen concentration;

[0021] Step 102, determining the target valve opening time according to the target oxygen supply and the preset flow rate of the oxygen mixing valve;

[0022] Step 103, controlling the oxygen mixing valve according to the target valve opening time.

[0023] In this embodiment, the target oxygen supply is first calculated according to the current operating parameters of the electric ventilator, the initial operating parameters at the be...

Abstract

The invention provides an oxygen mixing method for an electric respirator, which comprises the following steps: getting target oxygen supply amount by computation according to the current operation parameters of the electric respirator, initial operation parameters at the beginning of inspiration and preset target oxygen concentration; determining target valve opening time according to the target oxygen supply amount and the preset flow rate of an oxygen mixing valve; and controlling the oxygen mixing valve according to the target valve opening time. By adopting the oxygen mixing method, the oxygen mixing control precision is improved, the oxygen concentration can be adjusted continuously from 21% to 100%, and the problems that the oxygen mixing precision of the manual oxygen mixing method is poorer and the oxygen concentration can not be adjusted continuously from 21% to 100% in the prior art can be overcome.

Description

technical field [0001] The invention relates to the medical field, in particular to an oxygen mixing method for an electric ventilator. Background technique [0002] In order for the ventilator to output gas with adjustable oxygen concentration, it is necessary to control the ventilator for mixing oxygen. [0003] An oxygen mixing method for an electric ventilator is provided in the related art, and the oxygen mixing method is completed manually. [0004] The inventors found that the manual oxygen mixing method in the related art has poor oxygen mixing precision, and cannot realize continuous adjustment of oxygen concentration from 21% to 100%. Contents of the invention [0005] The purpose of the present invention is to provide an oxygen mixing method for an electric ventilator, which can solve the problem that the oxygen mixing accuracy of the manual oxygen mixing method in the related art is poor, and the oxygen concentration cannot be continuously adjusted from 21% to...
