Description

Technical field

[0001] The invention relates to a medical ventilator, in particular to an air-oxygen mixing system that adds a turbocharger device to the air intake port of the Venturi device of the venturi device to precisely control the output oxygen flow rate and oxygen concentration of the ventilator. Background technique

[0002] There are three kinds of traditional air-oxygen mixers: one is the two-way high-pressure gas provided by the central oxygen supply and medical air compressor, which is output to the patient after air-oxygen mixing and flow adjustment. Disadvantages such as high consumption, need to remove water, high cost, and large volume lead to a large volume of the ventilator system.

[0003] The second is the frictionless piston (or turbine) technology adopted abroad, which is mixed with oxygen and delivered to the patient. This device requires the piston valve (or turbine) to provide greater power, otherwise it will not meet the ventilation requirements. ...
