Description

Technical Field

[0001] The utility model relates to the technical field of blood separation, in particular to an automated platelet-rich plasma separator. Background Art

[0002] Platelet-rich plasma specifically refers to autologous plasma that contains more than 4 times the normal human platelet concentration. Platelets are cytoplasmic fragments of megakaryocytes and are formed in the bone marrow. They lack a nucleus, but contain organelles, as well as mitochondria, microtubules, various microparticulate structures and various growth factors. Since the growth factors in the above-mentioned platelets have many positive tissue repair-promoting effects, they have been widely used in dermatology, orthopedics, sports medicine, maxillofacial surgery, and plastic surgery. The existing separation device requires manual extraction of the clear liquid and enriched liquid in the test tube after centrifugal separation is completed. When manually grasping the syringe, the hand will shake, which will cause the separated plasma to mix again, resulting in a decrease in the concentration of platelets in PRP, reducing the preparation efficiency of PRP.
