Abstract

1471308 Membrane apparatus BAXTER TRAVENOL LABORATORIES INC 28 May 1974 [22 Aug 1973] 23539/74 Heading B1X A mass transfer apparatus, in which a porous hydrophobic membrane separates a liquid flow path and a gas flow path and includes a mass transfer device having a liquid inlet, a liquid outlet and a gas inlet and gas outlet, comprises means for maintaining a predetermined minimum liquid pressure adjacent the membrane, and gas pressure limiting means serving to vent gas in the gas flow path to prevent the pressure of the gas from exceeding the minimum pressure, the gas limiting means 60 comprising a container 62 with liquid 64 therein and a gas tube 66 communicating with the gas flow path 16 and which has an outlet 68 submerged in the liquid, the liquid in the container having a pressure head at the outlet that prevents gas from venting via the tube unless the gas pressure exceeds a predetermined gas pressure which is lower than the lowest pressure of liquid in the liquid flow path against the membrane. A second manometer (not shown) may also be incorporated. The apparatus is used for the extracorporeal oxygenation of blood.
