ABSTRACT:
A respirator device particularly for use in association with a tube insertable into a person's trachea comprises a trachea tube having an inflatable cuff which seals the tube with the person's trachea. A line for ventilating gas extends into the tube and terminates in a jet nozzle directed to the trachea. The opposite end of the tube is provided with a connection to atmosphere which also makes it possible to provide a controlled vacuum pressure at this end particularly in the expiration phase. Control is effected between the ventilating gas and the vacuum for regulating the respiration. With the inventive method the vacuum is provided at the outer end of the trachea tube particularly during respiration and it is effected by directing a vacuum pressure gas supply connection through a Venturi connection to the tube which produces the vacuum in the tube and communicates the tube to atmosphere. This gas connection is controlled along with a ventilating pressure gas connection to provide the desired respiration.
