Thrombus preparation method

The invention discloses a thrombus preparation method. The method includes following steps: (1), taking blood, and adding thrombin to obtain mixed liquid, wherein quantity of thrombin is 10-50/3 times of U/mL; (2), injecting the mixed liquid in the step (1) into a capillary plastic tube of 1mm in inner diameter, sealing, placing at 37 DEG C for 30 minutes, and then placing at 2-8 DEG C for 12-16 hours. Thrombus prepared by the method is high in coagulability, good in forming effect, high in stability, high in visual degree when being used for pulmonary arteriography, supportive of observing and judging blockage area more conveniently in real time and good in application prospect.
