BLOOD DEFOAMER WITH IMPROVED LIQUID SEAL Abstract A blood defoamer for use in surgical procedures is disclosed comprising a porous defoaming element, a non-porous end piece in contact with a surface of the defoaming element, and a layer of fabric affixed to the end piece adjacent to said surface. Bypass of blood flow around the layer of fabric, which is situated downstream of the defoaming element, and accumulation of bubbles in the defoamed blood reservoir are prevented by bonding a suitably configured retaining ring to the end piece with a portion of the layer of fabric held in a fluid-tight seal between the end piece and the retaining ring.
