Abstract

1385835 Blood oxygenator envelope assembly SCI-MED Inc 23 May 1973 [30 May 1972] 24573/73 Heading B1X A membrane envelope assembly for a spooltype blood oxygenator comprises a pair of rectangular gas permeable membrane sheets 14, 15, the sheets being bonded together to form peripheral seam 18 and a chamber between the sheets screen member 20 between the sheets and inlet or outlet tube 22 which may be of silicone rubber and may have a stainless steel spring (24) within it, tube 22 having a sleeve (26) surrounding one of its ends, this end and part of the sleeve being bonded within seam 18 and sleeve 26 having a transversely extending slit receiving screen 20. In the embodiment shown, the membrane sheets are protected from the edges of sleeve 26 by folded bib member 30, the bib member having a central opening and fitting closely around sleeve 26.
