1. a high frequency oscillator ventilator, comprises:

  • One housing unit;

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

    One linearity coil, it is placed coaxially in described linear actuators, and has through this linear lineThe push rod that circle axially extends, described linearity coil is supported on described by this push rod for axially slidablyOn linear actuators;

    The piston of one plate-like, it is arranged on one end of described push rod, and this piston has the circumference around this pistonThe flange that edge extends;

    The cover plate of one plate-like;

    The barrier film of one plate-like, described housing unit is divided into the first side and the second side by hermetically, should be everyFilm operationally engages with described piston, and this barrier film has the deep radius groove formed around the periphery of this barrier film,This barrier film is fixed between described piston and described cover plate;

    Wherein, described housing unit includes the cylinder-bore being arranged on described first side;

    Wherein, the flange of described cylinder-bore and described piston is separated by annular space, and described deep radiusGroove is arranged in described annular space, thus the reciprocating motion of described piston causes described groove to rush front and backRolling during journey;

    Wherein, described push rod extends through described piston, described barrier film and described cover plate;

    One opening, it is formed on described second side, and can with patient airway fluidly connect forIt transmits gas;

    AndWherein, described linearity coil and linear actuators coordinate the reciprocating motion realizing described barrier film, fromAnd the gas in described patient airway alternately produces positive and negative pressure Reeb.
