Abstract

1,001,854. Anaesthetic apparatus. O. H. DRAGER, [trading as DRAGERWERK, HEINR & BERNH DRAGER]. Oct. 3, 1962 [Nov. 18, 1961], No. 37465/62. Heading AST. In the type of anaesthetic apparatus in which part of the incoming gas passes through a vaporizing chamber while the remainder passes through an adjustable by-pass, a length of tubing is incorporated upstream of the vaporizing chamber. This prevents variations of pressure within the chamber, resulting from the patient's breathing, causing vapour to flow back into the by-pass where it might disturb the correct proportioning of vapour. Air or gas entering a distributer chamber 2 either passes through an adjustable valve 9 to the outlet 11 or through a long sinuous tube 12 to the evaporator 13 and so through a second control , valve 6 to the mixing chamber 8 and outlet 11. Any excess pressure produced in the chamber 13 by the patient's exhalation is unable to cause vapour to pass through the tube 12 to the chamber 2 before the direction of flow is reversed.
