美国克利夫兰人工脏器临床研究室的客座研究员林博士等用醛处理蛋白质或其它生物材料使之产生生物不活化性,并且有优良的生物适应性和强的抗血栓性等特性,这个过程就称之为“生物化处理”(Biolization)。他们用这个方法取得优质长寿命的材料,用来制造埋植式在心室辅助装置LVAD。该装置的主要特点:①装置的所有和血液接触的部分都用处理过的自然组织或蛋白质被覆着。②装置的泵体内部和血液接触的部分用戊二醛脱水处理过的心膜制成,外面再包以天然橡胶或聚氨酯。③泵入口处的三叶瓣膜用人的硬膜制成。④出口处使用戊
Dr. Clinic, a visiting researcher in Cleveland Clinic of Human Viscera Clinical Laboratory, aldehydes treated with aldehydes or other biological materials to produce biological inactivation, and has excellent biological adaptability and strong anti-thrombotic properties, the process is called It’s Biolization. They use this method to obtain high-quality, long-life materials that are used to create implantable LVADs in ventricular assist devices. The main features of the device: ① all parts of the device and the blood contact with the treated natural tissue or protein coated. ② The internal part of the pump body and blood contact device made of glutaraldehyde dehydration treatment of the pericardium, and then covered with natural rubber or polyurethane. ③ pump inlet trival valve made of human dura. ④ outlet use of e
