Platelet-rich plasma rapid separating device and method

Abstract

The invention relates to a platelet-rich plasma rapid separating device and a method, and belongs to the field of platelet-rich plasma extracting devices and methods. The device comprises a centrifugal tube; the centrifugal tube comprises an inner tube body, an outer tube body and a sealing cover, wherein the inner tube body is sleeved with the sealing cover; the inner tube body is provided with a shrinking channel, blood is centrifuged, then suction of cell components can be avoided in the mode that the channel is closed through a buckling device, the centrifugal operation procedure is simplified, and the concentration and the preparing efficiency of the platelet-rich plasma after centrifugation are increased; meanwhile, the outer tube body of the centrifugal tube is in a centrifugal-tube shape, the centrifugal tube can be in fit with a universal centrifugal device in the market, and a platelet-rich plasma enrichment device is easy to operate, low in cost and capable of providing a high-concentration and low-cost platelet-rich-plasma and platelet-rich-gel device and method for clinical research.

Description

[0001] 【Technical field】 [0002] The invention relates to a device and method for rapidly extracting platelet-rich plasma, and belongs to the field of platelet-rich plasma extraction equipment and methods. [0003] 【Background technique】 [0004] Platelet rich plasma (platelet rich plasma, PRP) is the platelet concentrate obtained by centrifugation and separation of whole blood, which is rich in platelets. When platelets are activated, they can release a variety of growth factors, which play an important role in promoting the proliferation, growth, differentiation and tissue formation of bone cells and osteoblasts. Since Marx et al first used PRP composite bone graft to repair mandibular defects in 1998, PRP has been gradually used in tissue repair in the fields of stomatology, plastic surgery, orthopedics, ENT, neurosurgery and other fields, as well as medical cosmetology and hair loss treatment. and anti-aging fields. [0005] At present, the preparation devices of platele...

AI Technical Summary

Problems solved by technology

[0005] At present, the preparation devices of platelet-rich plasma at home and abroad are based on density gradient centrifugation, buoy centrifugal enrichment, multi-bag separation, etc. Because the sterility of platelet-rich plasma must be maintained, these devices are generally complicated in structure and high in preparation costs. And it needs the supporting centrifuge device to assist in the separation

[0006] At present, the platelet-rich plasma preparation kits produced on the market are separated by centrifugation, which requires multiple extractions of liquid, which is complicated to operate; Aspirate samples, but the device requires a special centrifuge device, which is expensive

At the same time, these separation devices mostly use two centrifugation methods to enrich platelets. The operation process removes the cell components in the blood. The operation is complicated and easy to cause pollution. The enrichment speed of platelet-rich plasma is slow, which limits the clinical application of platelet-rich plasma.
