An antithrombogenic medical material with a remarkable antithrombogenic property and histocompatibility as well as sufficient physical strength, formed by fixing a heparinized collagen to a synthetic polymer material is provided. And a method of preparing an antithrombogenic medical material is provided, wherein a synthetic polymer material is subjected to a coating or impregnating treatment with a collagen-containing solution, followed by heparinization of the collagen, and the heparinized collagen is fixed to the synthetic polymer material. This method allows manufacturing of antithrombogenic medical material with ease. |
