Background
Blood is composed of plasma, platelets and red blood cells. Wherein the platelets contain all the components necessary for the regeneration and repair of human tissue. When blood is centrifuged, the three components are divided into three layers, namely, a plasma layer, a platelet layer and a red blood cell layer from top to bottom, according to their densities. The content located in the middle layer is Platelet-Rich and becomes Platelet-Rich Plasma (PRP). The upper layer is Platelet-Poor Plasma (PPP).
Platelets secrete a variety of growth factors following activation: leukocytes prevent infection, and fibrin can locally construct the three-dimensional structure required for tissue repair. The concentrated PRP component not only can provide concentrated nutrition for tissue repair, but also can build a better repair environment for tissue repair. A number of basic studies and clinical trials have demonstrated that PRP can significantly promote bone and soft tissue repair. Since PRP is from self, safe and effective, it has been widely used in clinical practice in recent years, and now it has been used in orthopedics, oromaxillofacial surgery, plastic surgery, cosmetology, sports medicine, neurosurgery, ophthalmology, otorhinolaryngology, and obstetrics and gynecology.
The method can obtain the autologous high-concentration PRP of a patient by drawing the venous whole blood of the patient through a secondary centrifugation method, wherein the secondary centrifugation method is the accepted most effective method for obtaining the PRP, namely, after red blood cells are centrifuged to the lowest layer after the red blood cells are centrifuged for the second time, the red blood cells are sucked from the bottommost layer to be discarded or used for other purposes, after the PRP is centrifuged to the lowest layer for standby, and the residual serum is discarded or used for other purposes.
