人工心脏用的抗血栓机械瓣膜的制作

The Manufacture of Cardiac Valve for Anticoagulative Artificial Heart

与人工心脏一体化的机械瓣膜，以确保血液以切向流经瓣膜界面，包括进、出口人工血管接口、机械瓣膜、搏动血膜在内的内无接缝的人工心脏血腔界面是由聚氨酯－肝素接枝共聚体制成，它具有抗血栓功能。本文介绍了人工心脏用的机械瓣膜的制作工艺过程。

The cardiac valve is casted with artificial heart into an integral whole. The flood must be tangent to its surface when it flows on or off the cardiac valve. The inside surface of the artificial heart include two artificial blood vessel joints, cardiac valve and pulse membrane are made of polyurethane-heparin graft-copolymer. It has an anticoagulative function. In this paper, the process technology of the cardiac valve for artificial heart is introduced
