Preparing method for platelet-rich gel

Abstract

The invention discloses a preparing method for platelet-rich gel. The preparing method for the platelet-rich gel includes the following steps that (1) a blood sampling connecting bag is taken and ready for blood sampling; (2) whole blood of blood donors is collected through a blood sampling device; (3) a whole blood bag is centrifuged, standing is carried out after centrifugation, and a plasma layer located on an upper layer, a PRP layer located on a middle layer and an erythrocyte layer located on a lower layer are formed; (4) plasma in the plasma layer flows into a plasma transferring bag through a first conduit, a fluid director and a third conduit in sequence, and then enters a plasma transferring illumination bag through a methylene blue releaser, and therefore plasma is prepared; (5)PRP in the PRP layer flows into a PRP bag through the first conduit, the fluid director and a second conduit in sequence, then an activating agent in an activating agent bag is added into the PRP bag, and therefore the platelet-rich gel is prepared. The preparing method is combined with blood sampling, the preparing amount is large, the possibility of blood pollution is reduced, the preparation procedure is simple, and time of workers is saved.

Description

technical field [0001] The invention relates to a preparation method of biological preparations, in particular to a preparation method of platelet-rich gel. Background technique [0002] Platelet Rich Plasma (Platelet Rich Plasma, referred to as PRP) is the plasma containing high concentration of platelets obtained by centrifugation of human whole blood; PRP contains high concentrations of platelets, and platelets contain a large number of growth factors, such as platelet-derived growth factor (PDGF ), transforming growth factor-β (TGF-β), insulin-like growth factor (IGF), epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), etc., these growth factors can Accurately locate the injury site, control inflammation, and promote cell and tissue regeneration from different aspects, thereby accelerating the repair of damaged tissue and greatly reducing the formation of postoperative scars. [0003] The principle of platelet-rich ...

AI Technical Summary

Problems solved by technology

At present, in the process of separating and extracting platelet-rich plasma, a complete set of devices consisting of several test tubes, syringes and other components is used. It needs to undergo multiple injections, centrifugation, and extraction. The operation is relatively complicated, and the amount of preparation at one time is small. Used, easy to cause pollution
