Title: Model artificial lung
Inventor: OHARA KOJIRO
IPC: A61M1/18
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of gas exchanging performance as caused by the retention of water in the internal surface of a hollow yarn by hydrophilic processing of a gas contact surface and a blood contact surface of the hollow yarn in an external perfusion type model artificial lung with which a gas flows to a hollow part of the hollow yarn while blood flows outside the hollow yarn. SOLUTION: In an external perfusion type model artificial lung with which a gas flows to a hollow part of a hollow yarn while blood flows outside the hollow yarn, a gas contact surface and a blood contact surface of the hollow yarn undergoes a hydrophilic treatment. The blood contact surface is further treated by an anti-thrombotic material and the anti-thrombotic material herein used is heparin. In this model artificial lung, even when passing as steam, the water in the blood will not be agglutinated and retained within the hollow yarn. This prevents the lowering of gas exchanging performance even in a prolonged use thereby achieving very high availability.
