目的对5种医疗器械进行体外血小板粘附试验研究。方法采用血小板计数法,分别对流经涂有甲基硅油的玻璃珠、空白玻璃珠和试验材料的血液进行血小板计数,计算血小板粘附率、检验材料血液相容性。结果试验结果表明体外血小板粘附试验能快捷、准确地对医疗器械进行评价,是医疗器械进行血液相容性评价的重要试验,从而为国家血液相容性评价标准化提供可靠的依据。 Objective To study the in vitro platelet adhesion test of five kinds of medical devices. Methods The platelet count method was used to count blood platelets flowing through the glass beads coated with methyl silicone oil, blank glass beads, and test materials, and the platelet adhesion rate and blood compatibility of the test materials were calculated. Results The test results show that the in vitro platelet adhesion test can quickly and accurately evaluate medical devices. It is an important test for blood compatibility evaluation of medical devices, thus providing a reliable basis for the national standardization of blood compatibility evaluation.
