Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 合成樹脂により形成された補助人工心臓であ っても、形成材料の物性の変化をあまり与えることな く、血液接触面にヘパリンが固定された補助人工心臓お よびその製造方法を提供する。 【構成】 ハウジングと、ハウジング内を血液室と、駆 動流体流入室とに区分する可撓性ダイヤフラムと、血液 室に連通する血液流入ポートと血液流出ポートと、駆動 流体流入室と連通する駆動流体流出入用ポートと、血液 流入ポートおよび血液流出ポート内に設けられた合成樹 脂製逆流防止弁を有し、逆流防止弁を含む血液接触面 は、オゾン処理により生成された基材表面の酸化物中に 含まれる官能基と、ヘパリンのアミノ基とが、直接、ま たは少なくとも一種のカップリング剤を介して共有結合 した抗血栓性表面となっている補助人工心臓である。 (57) [Summary] [Purpose] Even with an artificial heart made of synthetic resin, the artificial heart with heparin fixed to the blood contact surface and its production without changing the physical properties of the forming material. Provide a way. A flexible diaphragm that divides a housing into a blood chamber and a driving fluid inflow chamber, a blood inflow port and a blood outflow port communicating with the blood chamber, and a driving fluid communicating with the driving fluid inflow chamber It has an inflow / outflow port and a synthetic resin check valve provided in the blood inflow port and the blood outflow port, and the blood contact surface including the check valve is an oxide of the surface of the base material generated by ozone treatment. The auxiliary artificial heart has an antithrombotic surface in which a functional group contained therein and an amino group of heparin are covalently bonded directly or via at least one coupling agent.
