AIR PULSE GENERATOR IN HIGH FREQUENCY OPERATED RESPIRATOR

摘要

An apparatus for the high-frequency artificial respiration of living animals or human beings has a flexible endotracheal tube for introduction into the trachea thereof. The flexible endotracheal tube has an outlet end, a valve at the outlet end and control and air supplies along the endotracheal tube to the valve. The control operates the valve to produce steep-flanked respiratory-air pulses. The valve can serve simultaneously for removing used air through a conventional endotracheal tube as a sleeve about the other endotracheal tube.
