Title:
APPARATUS AND METHOD FOR SMOOTHING GAS MIXING AND STREAM
Document Type and Number:
Japanese Patent JPS59189927
Kind Code:
A
Abstract:
Gas mixing and flow smoothing apparatus for use in for example an anaesthesia system comprises a mixing chamber (8) which receives the flow of two or more gases via control valves (6, 7). The mixing chamber (8) is adapted to absorb fluctuations in the pressure of the gases therein through the provision of for example a spring-loaded piston (not shown) which forms one wall of the chamber, and the pressure at the outlet (30) from the chamber (8) is maintained at a substantially constant pressure by means of a valve (9). If desired, further attenuation of the gas flow may be achieved through the provision of a second series arrangement of surge damper (11) and back pressure valve (10) located downstream from the valve (9).
