1. , a kind of high frequency oscillator ventilator comprises:

  • One housing unit;

    One linear actuators, it is fixedly mounted in the described housing unit;

    One linearity coil, it is arranged in the described linear actuators coaxially, and has and pass the push rod that this linearity coil axially extends, and this push rod is used for slidably described linearity coil being supported on described linear actuators;

    One piston, it is installed in an end of described push rod;

    One barrier film, it is divided into described housing unit first side and second side hermetically, and this barrier film operationally engages with described piston;

    WithOne opening, it is formed on described second side, and is connected to be used for to its transport gas with the patient airway fluid;


    Described linearity coil and linear actuators cooperate realizes described membranous reciprocating motion, thereby alternately produces the positive and negative pressure Reeb in the gas in described patient airway.
