ABSTRACT:
A device for supporting human breathing and artificial respiration particularly for newborn infants by supplying breathing gas to the trachea of the infant comprises a trachea tube which is adapted to be connected into the trachea of the infant and which is connected at its opposite end to a tubular member which defines a pressure chamber therein. The tubular member is opened at its outer end and the pressure inside the tubular member is regulated by directing a jet of breathing gas directly into the pressure chamber within the member in accordance with the pressure condition monitored in the trachea tube. One or more of the gas jets may terminate in the pressure chamber preferably in a direction transverse to the flow passage therethrough from the opening to the trachea tube. The jets may also be used to aspirate moisture into the tube for delivery with the breathing gas to the trachea. The opening of the pressure member may be controlled in accordance with a valve member which may comprise a pivotal disc or an inflatable balloon for example.
