A kind of method of removing white filter to improve the recovery rate of red blood cells

Abstract

The invention provides a method for improving the recovery rate of red blood cells by removing the white filter, comprising the following steps: firstly, preparing 0.9% sodium chloride injection to be filled; secondly, using a peristaltic pump to fill the 0.9% sodium chloride injection into the In the white filter, the total filling volume is 0.6ml‑2.0ml; finally, store the white filter after filling with 0.9% sodium chloride injection for a certain period of time before use. After the stored white filter in the present invention is put into clinical application, since the filter membrane therein is soaked by 0.9% sodium chloride injection, when the blood passes through the white filter to filter out leukocytes, the white filter will The adsorption of red blood cells by the filter membrane will be greatly reduced, thereby reducing or eliminating the hemolysis quality problem of the white filter when filtering white blood cells, thereby effectively improving the recovery rate of red blood cells. The entire operation process is simple and the implementation cost is low. , effectively reducing the application cost of red blood cells, and reducing unnecessary waste of blood resources.

Description

technical field [0001] The invention relates to the technical field of white filter applications, in particular to a method for improving red blood cell recovery by a white filter. Background technique [0002] In order to prevent the generation of adverse reactions of blood transfusion and the infection of blood transfusion-associated viruses, white blood filter (also known as "leukocyte filter") is usually used clinically to effectively remove white blood cells, so as to reduce the amount of platelets and the incidence of adverse reactions caused by blood transfusion, and reduce the Incidence of postoperative infection due to blood transfusion. [0003] The current de-white filter products, the sterilization operation in the production process is relatively complicated, and the sterilization cost is relatively high. In addition, the complexity of the structure of the white-removal filter product itself easily leads to incomplete sterilization of the white-removal filter, r...

AI Technical Summary

Problems solved by technology

The continuous accumulation of these blood clots not only easily causes the blockage of the white filter, affects the filtration effect of white blood cells, but also reduces the recovery rate of red blood cells, resulting in high application costs of red blood cells and unnecessary waste of blood resources.
