Abstract
Description
Technical Field
[0001] This utility model relates to the field of hole punching machine technology, and in particular to a new PRP production kit. Background Technology
[0002] PRP, short for "high-concentration platelet plasma," is a highly concentrated plasma rich in platelets produced from one's own blood. Due to its high content of growth factors, PRP promotes wound healing, reduces scar formation, and relieves pain. It is widely used in sports injuries such as osteoarthritis, synovitis, cartilage damage, tennis elbow, and Achilles tendinitis, as well as in orthopedic surgeries such as joint replacement surgery, fracture treatment, and prevention of nonunion.
[0003] For example, a syringe with authorization announcement number CN204106746U, by having both the first and second pistons made of rubber, can be used as both a regular syringe and a micro-syringe.
[0004] However, there are still some problems with the use of the syringes mentioned above. For example, the syringes mentioned above can only perform simple blood sampling operations and cannot meet the various requirements of PRP preparation. When PRP is prepared, it is necessary to accurately control the blood draw from the donor. In addition, in order to ensure the normal operation of the subsequent high-speed centrifugation, it is also necessary to ensure that the blood sample is accurately drawn to 20ml. However, the current syringes can only achieve the blood sampling process, and the final amount of blood drawn can only be estimated by manually visually judging the corresponding scale value on the syringe. Therefore, the existing syringes cannot meet the needs of high-precision blood drawing for PRP. Utility Model Content
[0005] This invention aims to solve the problems existing in the prior art by providing a new PRP production kit, which achieves better PRP production results.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

The inner side of the blood collection tube is provided with a PRP fabrication injection structure, and the front end of the blood collection tube is provided with a connecting tube structure and a blood collection needle structure.
[0008] Further improvements include a detachable push rod and a locking push rod for PRP injection. The detachable push rod is slidably connected to the inside of the evacuation tube, and a first piston head is fixedly installed at the front end of the detachable push rod. The first piston head is slidably connected to the inner wall of the evacuation tube. The locking push rod is slidably connected to the inside of the PRP sampling tube, and a second piston head is fixedly connected at the front end of the locking push rod. The outer wall of the second piston head is slidably connected to the inner wall of the PRP sampling tube. A first connector is fixedly connected at the front end of the evacuation tube, and a second connector is fixedly connected at the front end of the PRP sampling tube. Threaded grooves are fixedly formed on the inner wall ends of the first and second connectors.
[0009] Further improvements include the connector structure comprising a connector body and a housing. The connector body is movably inserted into the front end of the blood collection tube. A connecting hole is fixedly opened inside the connector body. Housings are fixedly connected to both ends of the connector body. Threaded holes are fixedly opened on the outer sides of the two housings.
[0010] Further improvements include connecting the outer side of the threaded hole to the external thread of the threaded groove on one side of the end of the sampling tube, and connecting the other side of the threaded hole to the threaded groove on the inner side of the end of the PRP sampling tube.
[0011] Further improvements include a mounting block, which is threadedly connected to the inner side of the threaded groove at the front end of the blood collection tube. A blood collection tube is fixedly connected to the rear side of the mounting block, and a blood collection needle is fixedly connected to the other end of the blood collection tube.
[0012] Furthermore, the front ends of the blood collection tube and the PRP sampling tube are also provided with needle structures. The two needle structures include reinforcing rings and connecting rings. The outer sides of the two connecting rings are threadedly connected to the threaded grooves at the front ends of the blood collection tube and the PRP sampling tube. The other side of the two connecting rings is fixedly connected to the reinforcing rings, and the other end of the two reinforcing rings is fixedly connected to the needles.
[0013] The beneficial effects of this utility model are as follows: This utility model allows the detachable push rod to push the first piston head at the front end, enabling it to slide and pull inside the blood collection tube. The first piston head creates negative pressure inside the blood collection tube to achieve blood collection, delivery, and connection to the PRP sampling tube for PRP preparation. The detachable push rod can be pulled out after the blood collection is complete. The PRP sampling tube is designed with a short and thick structure, with a maximum capacity of 20ml. The short and thick design allows it to be locked in place without requiring a blood collection operation. Using two syringes, one long and one short and thick, a quantitative blood delivery to the PRP sampling tube can be achieved, enabling a more precise and efficient PRP preparation process and improving the effectiveness of the new PRP preparation kit.
