Platelet enrichment fluid

Abstract

The invention discloses platelet enrichment fluid. The platelet enrichment fluid is prepared from the following raw materials in parts by weight: 2 to 2.5 % of sodium citrate, 0.6 to 1 part of citricacid, 2.1 to 2.5 % of glucose, 2.5 to 3.5 % of hydroxyethyl starch 200 / 0.5, 2.5 to 3.5 % of dextran 70 and 87 to 90.3 % of distilled water. The platelet enrichment fluid can change the specific gravity of centrifuged plasma to 1.04 to 1.05 and the osmotic pressure of the enrichment fluid is isotonic to hemocyte. Therefore, after one-time centrifuging, because the specific gravity of the platelet in a blood-collection tube is smaller than that of the plasma, the platelet is enriched on the upper layer of the plasma, and the loss of the platelet caused by metastasis is prevented; in addition, according to the method, operation procedures are greatly simplified, thereby reducing pollution.

Description

technical field [0001] The invention belongs to the field of medical clinical plastic surgery, and relates to a blood collection tube additive for increasing the concentration of platelets in prepared platelet-rich plasma (PRP), in particular to a platelet enrichment solution. Background technique [0002] Platelet-rich plasma (PRP) currently used in the field of medical clinical plastic surgery is mostly obtained by secondary centrifugation using the difference in the proportion of each component in the blood. The specific gravity of blood cells in blood is 1.07-1.10, the specific gravity of platelets is 1.030-1.04, and the specific gravity of plasma is 1.025-1.030. After centrifugation, platelets will be in the lower layer of plasma. When preparing PRP, the autologous blood is first collected in blood collection tubes added with blood preservation solution (ACD solution), and then all the supernatant is taken out by one centrifugation immediately and transferred to another...

AI Technical Summary

Problems solved by technology

But this single blood preservation solution can only anticoagulate blood and maintain the basic shape of blood cells

However, for the biggest problem in the current extraction of platelet-rich plasma (PRP): increasing the concentration of platelets in the prepared platelet-rich plasma, simplifying the operation steps, and reducing pollution have no obvious effect.
