Problems solved by technology

This type of method is cumbersome to operate and difficult to control. The platelet content in PRP obtained by different operators varies greatly, and the platelet enrichment degree is low, which is only 2 to 4 times the platelet concentration in whole blood.
More importantly, during the transfer process of the second centrifugation, it is likely to cause bacterial contamination, which poses a safety threat to patients

Embodiment Construction

[0040] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0041] Such as Figure 1~6 As shown, the disposable platelet-rich plasma separation device of this embodiment includes an upper cover 1, a cylinder body 2, a lower cover 4, a PRP cylinder 9, an inner sleeve 11 and a baffle 5;

[0042] The upper cover 1 and the lower cover 4 are respectively sealedly connected with the cylinder body 2 from the upper and lower ends to form a cylinder. In this embodiment, the upper cover 1, the lower cover 4 and the cylinder body 2 are all connected by threads. It should be ensured that it is smooth when rotating, and should not consume great effort or a sense of sluggishness. One is to facilitate the rotation and adjustment of the interface, and the other is to prevent sudden changes in force when the interface is adjusted to cause vibration and disturb the interface; the lower cover 4 is made of rubber In order to ensure ...

Abstract

The invention particularly relates to a disposable platelet-rich plasma separation device, which is used for realizing aseptic disposable PRP separation in the whole process, and comprises an upper cover, a cylinder body, a lower cover, a PRP cylinder, an inner bushing and a baffle. According to the invention, separation can be completed by only one-time centrifugation without plasma transfer, sothat the operation is more convenient; transfer is not needed, so that the blood is completely isolated from the outside in the whole process so as to fundamentally reduce the possibility of being polluted; PRP can be collected in the PRP cylinder, so that the platelet enrichment degree is high, and the highest platelet enrichment degree can be about 50 times; the platelet enrichment degree can beautonomously adjusted as required, so that the operation is convenient; and in the operation process, the platelet loss is small, the difference is not too large when different persons operate, and the consistency of the PRP quality can be better guaranteed.

Description

Technical field [0001] The invention relates to a disposable platelet-rich plasma separation device, which is used for realizing sterile and disposable PRP separation in the whole process. Background technique [0002] Platelet-rich plasma (PRP), as a self-derived medical ingredient, is natural and will not be rejected by the body and is safer in application. Platelets are a key cell component to maintain the balance of blood coagulation in the human body, and play a vital role in hemostasis. But in addition to hemostasis, platelets also play a very important role in wound healing, tissue regeneration, fracture healing, etc. This is mainly because platelet cells not only contain coagulation-related factors, but also have serotonin and platelet growth. Factors, transforming growth factors, etc., especially platelet growth factor and transforming growth factor, which are released by platelets in large quantities can induce surrounding cells to produce more factors, such as epiderm...
