Abstract： |
A biological material of blood compatiblility and the preparing method, relating to a biological material of blood compatible used externally or be implanted into body and the preparing method. Dissolving the medical high molecular material of high mechanical property and anticoagulant material with two different solvent and mixing them, fixing the anticoagulant material in the high molecular material uniformly, and preparing the restoring material for tissue organs used externally or be implanted into body with normal process, the invention overcomes the shortcomings existing in traditional technique of not obvious effect or for a short time of the anticoagulant modifying caused by only adsorbing, coating or grafting on the product surface, and makes the material possesses good anticoagulant property and prolongs the anticoagulant durability, and can meet demands of good anticoagulant, biological compatibility, strong mechanical strength and toughness needed by the restoring material for tissue organs used externally or be implanted into body. |
