Abstract: A safety system is provided for a membrane-type blood oxygenator to prevent the possibility of gas embolism through the membranous barrier which separates the blood and the oxygen. The safety system includes a blood reservoir positioned at a higher horizontal level than the blood inlet of the oxygenator, so that a gravity head is maintained. In addition, a manometer is provided which has a fluid level to permit venting of the oxygen if the oxygen pressure exceeds a predetermined gas pressure, which gas pressure is lower than the minimum pressure of the blood in the oxygenator.

Abstract: A fluid diffusion cell having a diffusion membrane folded to define a first set and a second set of oppositely opening pockets. Each pocket in both sets contains a support member, and a pair of manifolds are provided to provide a fluid inlet and outlet at opposite ends of each of said sets of pockets to permit fluid to pass from each inlet into one end of each of the pockets of one set, to pass through each of the pockets and the outlet.
