摘要：Heparin coating technology has become increasingly mature, which is conducive to the material of blood, biocompatibility proved very important, therefore, heparin coating technique has become a development cycle is very useful for in vitro selection of patients. On the other hand, the overall cost of medical treatment will increase because of the use of heparin coated materials and devices, so the clinical use of heparin coated materials is limited. In this paper, the principle of heparin coating technology, heparin coating technology should be applied in the norms of the external circulation, and related heparin coating technology development status analysis.
