TECHNICAL FIELD

[0001] The utility model belongs to the blood separation technical field, specifically, the utility model relates to a kind of platelet-rich plasma extraction auxiliary device. BACKGROUND

[0002] The various cells contained in blood are mainly composed of the following components, including plasma, red blood cells, white blood cells and platelets, and different components of platelet-rich plasma can be formed according to different contents of red blood cells, white blood cells, plasma and platelets, Different components of platelet-rich plasma are divided into platelet-rich plasma (L-PRP) containing a small amount of red blood cells and white blood cells, and platelet-rich plasma (P-PRP) containing no red blood cells or a small amount of white blood cells.

[0003] Platelet-rich plasma (PRP) is obtained by extracting a certain amount of venous blood, removing excess red blood cells and plasma after centrifugation, and contains a variety of growth factors such as cytokines, platelet-derived growth factors, transforming growth factor-β1, vascular endothelial growth factor, etc. If PRP is transplanted to the affected area, especially the early human bone cartilage, ligament, muscle, etc. (patient) site, it can also stimulate surrounding stem cells to help cell production, Therefore, PRP is increasingly widely used in clinical, orthopedic, cosmetic, pain and other fields.

[0004] In the prior art, PRP is extracted by centrifuging venous blood in a centrifuge, and the blood is collected after centrifugation. The centrifugation is performed using a centrifuge tube, and the collection is performed by tilting or vertically holding the centrifuge tube. The tilting operation affects the layering effect, and the collection effect is not good. A syringe is used to replace the centrifuge tube for centrifugation, and the collection is performed from the bottom of the syringe. The collection effect is good, but the syringe needs to be manually operated for layering during the layering operation. During this process, the syringe inevitably tilts, and cannot be kept stable all the time. The syringe cannot be kept in a vertical direction during the layering collection process, and the stability of the extraction pressure and speed cannot be ensured during the hand-holding extraction or injection operation, resulting in a significant reduction in the efficiency of extracting platelets and affecting the clinical treatment effect. Therefore, it is necessary to design and produce an auxiliary device for supporting the syringe for layering and extracting platelet-rich plasma. UTILITY MODEL CONTENTS
