Preliminary report on the development and evaluation of a new membrane lung (WASHI lung)

The oxygenating efficiency of our own membrane lung was studied in vitro using oxygen transfer and rated blood flow. Arch or convex type design had a better oxygenating performance compared with plain boad type one. Our new WASHI lung showed a excellent value of rated blood flow, 1.92L/Min/M2. The o...

Summary:The oxygenating efficiency of our own membrane lung was studied in vitro using oxygen transfer and rated blood flow. Arch or convex type design had a better oxygenating performance compared with plain boad type one. Our new WASHI lung showed a excellent value of rated blood flow, 1.92L/Min/M2. The oxygenating efficiency was compared between four kinds of silicon membrane, i. e. polyester unfabricated sheet with 130 micron silicon coating layer, 40 to 50 micron silicon coating layer, plain silicon film, Sci. Med. silicon support film. The pressure drop between the inlet and outlet of our lung was not so prominent compared with Kolobow membrane lung.
