Abstract

The invention discloses a growth factor extraction device. The growth factor extraction device comprises a centrifugal machine, an inflation mechanism and a plurality of centrifugal units, a plurality of mounting holes are formed in a centrifugal table of the centrifugal machine, and an inflation connector is arranged at the bottom of each mounting hole. The inflating mechanism is used for inflating each inflating connector; the centrifugal unit comprises a lower cylindrical body and an upper cylindrical body; a centrifugal cavity is formed in the lower cylindrical body, a piston is arranged in the centrifugal cavity in a matched mode, a connector is coaxially arranged at the lower end of the lower cylindrical body, and the lower end of the lower cylindrical body is inserted into a mounting hole and is in threaded connection with the inflation connector through the connector; the lower end of the upper cylindrical body is detachably and rotatably connected with the upper end of the lower cylindrical body, and a leucocyte cavity, a platelet cavity and an erythrocyte cavity are arranged in the upper cylindrical body. According to the device, red blood cells, white blood cells and platelets can be automatically separated after blood is centrifuged and layered, the separation difficulty is reduced, the separation efficiency is improved, separation is more thorough, and platelet gel is not prone to being damaged in the separation process.

Description

technical field [0001] The invention relates to the technical field of growth factor extraction, in particular to a growth factor extraction device. Background technique [0002] Growth factors (CGFs) are a class of polypeptides that regulate cell growth and other cellular functions by binding to specific, high-affinity cell membrane receptors. They are present in platelets and various adult and embryonic tissues and most In cultured cells, it can be injected into hard tissue defects or soft tissue wounds alone or in combination with other biomaterials, thereby repairing defects, inducing growth, accelerating the healing of local wounds and improving the quality of healing, and has the effect of improving and enhancing tissue regeneration. [0003] Blood contains red blood cells, white blood cells, platelets, etc., and growth factors mainly exist in platelets. Therefore, when extracting growth factors, it is necessary to separate red blood cells, white blood cells and platel...
