Abstract

The invention provides a piston type medical centrifuge tube. The piston type medical centrifuge tube comprises a centrifuge tube body and a piston arranged in the centrifuge tube body, wherein the bottom of the centrifuge tube is provided with a nipple, one end of the nipple is connected with the centrifuge tube, and the other end of the nipple is detachably connected with a nipple cover and/or a conversion port; an external column is arranged above the piston and detachably connected with a long handle; the piston type medical centrifuge tube can also comprise an aseptic packaging bag used for storing all parts subjected to bactericidal treatment. The invention further provides a preparation method of the platelet rich plasma which is prepared by means of the piston type medical centrifuge tube. The piston type medical centrifuge tube can improve convenience of making PRP, sample contamination which occurs in the operation process can be completely avoided, the platelet collection rate can be further increased, doping of impurities such as red blood cells and white blood cells is reduced, and different kinds of PRP can be collected according to different usage modes.

Description

technical field [0001] The invention relates to a medical device, in particular to a piston-type medical centrifuge tube and a preparation method for preparing platelet-rich plasma. Background technique [0002] Platelet-rich plasma (PRP) is isolated from blood and contains transforming growth factor-β (transforming growth factor, TGF), platelet-derived growth factor (platelet-derived growth factor, PDGF), insulin-like growth factor (insulin-like growth factor, IGF ) and vascular endothelial growth factor (vascular endothelial growth factor, VEGF) and other growth factors, in addition to leukocytes and fibrin. Many studies have shown that PRP is of great significance to soft tissue repair, can promote cartilage regeneration, and at the same time slow down cartilage degeneration. Therefore, PRP has now become a hot topic in the current field of cartilage repair. [0003] In fact, different tissues in the human body have different requirements for PRP used for repair. For ex...
