Description

Apparatus for Separation of Constants of Biofluid Comprising Needle Support The disclosure relates to a body fluid component separation device, for example, to a body fluid component separation device including a needle support. Human body fluids, such as blood and bone marrow, contain various active ingredients and cells. Among these, plasma contained in blood is a neutral yellow liquid component obtained by separating and removing red blood cells from the blood. Platelet-rich plasma (PRP), obtained by centrifuging plasma, performs various functions in vivo, including acting as glue, blood coagulation and hemostasis, acting as a scaffold for the migration and differentiation of stem cells and primary cells, regulating angiogenesis, anti-inflammatory action, antibacterial action, and analgesic action. In particular, as it is associated with tissue regeneration, such as cell proliferation, differentiation promotion, and angiogenesis in tendons, ligaments, cartilage, and muscles, the clinical efficacy of PRP in cases of musculoskeletal injury is receiving attention. For example, Korean Patent Publication No. 10-2019-0059019 discloses a blood component centrifugation device. The aforementioned background technology was possessed or acquired during the process of deriving the present disclosure and cannot be considered as prior art disclosed to the general public prior to the filing of the present disclosure.
