Kit for integrally preparing autologous platelet-rich plasma

Abstract

The invention relates to a kit for integrally preparing autologous platelet-rich plasma. The kit comprises a plasma storage pipe, a connecting pipe and an erythrocyte storage pipe seal cover, wherein the connecting pipe sequentially comprises a PRP storage pipe, a locking pipe and an erythrocyte storage pipe which are integrated; the plasma storage pipe is in threaded connection with the PRP storage pipe; the erythrocyte storage pipe is in threaded connection with the erythrocyte storage pipe seal cover; a plasma extraction draining pipe and a PRP extraction draining pipe are arranged in the plasma storage pipe, and the length of the PRP extraction draining pipe is more than that of the plasma extraction draining pipe; a plasma extraction opening and a PRP extraction opening are formed in the top of the plasma storage pipe, the plasma extraction opening is communicated with the plasma extraction draining pipe, and the PRP extraction opening is communicated with the PRP extraction draining pipe; an erythrocyte locking plug is arranged in the locking pipe; the opening formed in the bottom of the plasma storage pipe is matched with the erythrocyte locking plug. The kit has the advantage of completing the whole extraction process in an integral device, is simple, quick and efficient, and is hardly polluted.

Description

technical field [0001] The invention relates to a platelet-rich gel (plasma) extraction device, in particular to an integrated set for the preparation of autologous platelet-rich plasma, which belongs to the field of medical devices. Background technique [0002] Platelet Rich Plasma (PRP) is a plasma containing high concentrations of platelets obtained from autologous whole blood by centrifugation. PRP contains high concentrations of platelets, and platelets contain a large amount 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 precisely self-localize to the injury site, control inflammation, and promote cell and tissue regeneration from different aspects, thereby accelerating damaged tissue It has a repairing effect and greatly reduces the formation ...

AI Technical Summary

Problems solved by technology

At present, a complete set of devices consisting of several test tubes, syringes and other components is used in the separation and extraction process, which requires multiple injections, centrifugation, and extraction. The operation is relatively complicated, and several components are used separately and sequentially, which is easy to cause pollution.

Moreover, due to the variability of blood samples, it is difficult for existing separation devices to effectively collect the platelet-rich plasma layer
