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.

Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] in the use of such as figure 1 When the process shown in the process is used to sterilize the white filter, the specific operation steps are as follows:
[0022] Step 1, prepare 500ml or other 0.9% sodium chloride injection with sufficient volume and a peristaltic pump; the peristaltic pump used is preferably an intelligent peristaltic pump, such as DT / 601F intelligent peristaltic pump.
[0023] Step 2: Connect the ready-to-use 0.9% sodium chloride injection to the liquid inlet of the peristaltic pump, and connect the liquid outlet of the peristaltic pump to the blood inlet of the white fi...

The invention provides a leukocyte filter sterilization process which includes the steps: firstly, preparing 0.9% sodium chloride injection to be injected, and totally injecting 0.6-2.0ml of the 0.9% sodium chloride injection into a leukocyte filter to be sterilized by a peristaltic pump; secondly, sealing the leukocyte filter to be sterilized after injecting the 0.9% sodium chloride injection, and performing steam sterilization at the temperature of 100-120 DEG C for 50-30 minutes; finally, taking out the sterilized leukocyte filter. The used 0.9% sodium chloride injection has a certain sterilization function, the sodium chloride injection inside the leukocyte filter forms steam at high temperature in the steam sterilization process of the leukocyte filter, the steam formed by the 0.9% sodium chloride injection is better in heat penetration, so that the inside of the leukocyte filter can be sufficiently and thoroughly sterilized, sterilization reliability is high, and the leukocyte filter sterilization process has the outstanding advantages of simplicity in operation, low implementation cost and the like.
Description
technical field [0001] The invention relates to the technical field of whitening filter sterilization, in particular to a whitening filter sterilization process with simple sterilization operation. 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-...
