[0002] Platelet-rich plasma is a kind of plasma rich in platelets obtained by centrifuging animal or human whole blood. It can become a colloid after adding thrombin, so it is also called platelet-rich gel or platelet-rich leukocyte gel (PLG). PRP contains a large number of growth factors such as platelet-derived growth factor (PDGF), transforming growth factor β (TGF-β), insulin-like growth factor 1 (IGF-1), etc., and a platelet-rich plasma centrifuge device is required for preparation.

[0010] Preferably, the transverse grooves and the vertical grooves are arranged alternately, the transverse grooves are arranged to penetrate the interior of the connecting tube, and the depth of the vertical grooves is smaller than the depth of the transverse grooves.

[0011] Compared with the prior art, the beneficial effects of the utility model are:
