Preparation process of platelet-rich plasma and application of platelet-rich plasma product

The invention provides a platelet-rich plasma preparation process and application of a platelet-rich plasma product, and the platelet-rich plasma preparation process comprises the following steps: adding a water repellent agent into a separation gel, so that the water contact angle of the separation gel reaches 130-180 degrees; and finally preparing the platelet-rich plasma, namely the PRP, by matching with an operation mode that the PPP with the volume of 70%-80% of the liquid above the PPP layer obtained by layering is transferred, and then the blood collecting tube is slightly shaken to suspend the platelets and the leukocytes in the remaining PPP. According to the invention, the absorption effect of the separation gel on platelet and leukocyte layers is reduced, favorable conditions are provided for separating platelets and leukocytes from the separation gel and suspending the platelets and leukocytes in the PPP, the operation is simplified, the stability of the operation is improved, meanwhile, the recov
