  • Laminated carbon-containing silicone rubber membrane for use in membrane artificial lung
    Patent number: 4093515
    Abstract: A blood-compatible gas-permeable laminated carbon-containing silicone rubber membrane for use in a membrane artificial lung. The membrane is composed of at least two layers wherein the first layer is of silicone rubber compounded with silica filler and the second layer is of silicone rubber compounded with carbon black filler. The second layer may be sandwiched between the first layer and a third layer of either silicone rubber compounded with silica filler or filler-free silicone rubber. Utilizing such membrane for extracorporeal blood gas exchange in a membrane artifical lung results in elimination of thrombosis without the necessity for maintenance anticoagulant treatment during perfursion, and enables elimination of leukopenia and granulocytopenia or inhibition of blood platelet count decreases during perfusion.
