Abstract

The invention provides a double-cannula centrifugal injector. The double-cannula centrifugal injector comprises an outer cannula and an inner cannula. The whole set of process of blood sampling, centrifuging, extracting and injection can be completed by arranging the outer cannula and the inner cannula capable of being in cooperation with the outer cannula and using the double-cannula centrifugal injector, so that the operation process is simple, and the working efficiency is higher. In addition, due to a specially-designed outer piston, in the extraction operation process after centrifuging, operation is more convenient, it can be avoided that plasma containing erythrocyte is mistakenly sucked, the thrombocyte-containing plasma obtained through separation can be extracted into the inner cannula to the maximum degree, waste of the plasma can be avoided, and treatment demands are met.

Description

technical field

[0001] The invention relates to the technical field of medical equipment, in particular to a double sleeve centrifugal syringe. Background technique

[0002] High-concentration platelet-rich plasma (PlateletRichPlasma, referred to as PRP), is the plasma containing high-concentration platelets obtained by centrifuging blood. PRP contains a large amount of growth factors, which can quickly stop bleeding, relieve pain, accelerate wound healing, and accelerate tissue repair, which can greatly reduce the formation of postoperative scars. In addition, because PRP can be extracted from the patient's own blood, after extraction and enrichment, it can be used for the treatment of related diseases, so the source is rich, the material is convenient, the preparation method is simple, and it can be absorbed by the body. The use of self-PRP can avoid the problems of virus transmission and immune rejection. Therefore, PRP is widely used in various surgical operations, hea...
