Abstract

The invention belongs to the technical field of preparation of platelet rich plasma and in particular discloses a method for preparing PRP (Platelet Rich Plasma) through a one-step centrifugation method. According to the method, only a high-speed automatic centrifuge is utilized, the one-step centrifugation method is adopted, only one-step liquor relief (which is used for absorbing plasma on a boundary layer) is required in the whole process, and the purposes of convenience, rapidness and low pollution risk are achieved. Moreover, according to the platelet rich plasma prepared by the method, a mean value of platelet cell concentrations reaches 1029.875*10<9> / L, the mean corpuscular hemoglobin in the PRP is 20.26 g / L, and the clinical requirements can be well met.

Description

technical field [0001] The invention relates to a method for preparing platelet-rich plasma, in particular to a method for preparing platelet-rich plasma by a single centrifugation method. Background technique [0002] Platelet-rich plasma (platelet-rich plasma, PRP) is the plasma containing high volume fraction of platelets obtained by centrifuging the whole blood of human or animal itself. Since DAVID R. KNIGHTON and others discovered that platelet cells can promote vascular proliferation and collagen synthesis in the 1980s, people have devoted themselves to clinical application of platelet-rich plasma (PRP), eager to solve the problem of repairing the damage of organs and tissues with low repair ability. . However, due to the difficulty in preparing PRP at that time, its clinical promotion was limited. [0003] After decades of research, several more suitable methods for preparing platelet-rich plasma have been explored: manual methods (one-time centrifugation, two-tim...
