Anaesthetic apparatus with circulation of respiratory gases

Abstract

A through chamber, which functions as a circulation enforcing unit, is placed in the closed gas flow circuit. /3/. Inside the ventricle there is located a ventilator /4/. The aforementioned chamber /3/ is of cylinder shape and its axis is aligned with the axis of the ventilator's 4b rotor 4a connected with the shaft of an electric motor /4b/ with adjustable rotational speed. The through chamber /3/ has a connector /5/ joining it to the breathing bag /6/ and the anaesthetic substance evaporator /7/. The outlet of the connector /5/ is placed at the pressure side of the ventilator /4/, whereas the connecting element /8, 9/ is led out from a part of the closed circuit located between the absorber /2/ and the enforcing unit. The connecting element is an intubation tube /8/ or mask /9/ adjusted to the patient's face.
