Embodiment Construction

[0016] According to the analysis, the impact of the low penetrating ability of the electron beam on the blood purification product after sterilization is: when one side is irradiated, the electron beam cannot completely penetrate the two ends of the blood purification product with higher density, thus failing to achieve the purpose of sterilization . The impact of uneven distribution of electron beams on blood purification products after sterilization is that when both sides are irradiated, although the electron beams penetrate the two ends of the blood purification products with higher density, the remaining parts may receive excessive doses , there is some damage to the material.

[0017] In view of the above-mentioned problems, the electron beam sterilization method of the present invention makes the parts with higher density at both ends of the blood purification products in each layer of the package not overlap with the same parts of the blood purification products in oth...

Abstract

The invention relates to an electron beam sterilization method for a blood purifying product. According to the electron beam sterilization method disclosed by the invention, a dialyzer can be sterilized by using electron beams through two-side radiation and a method for dislocating a higher-density part of the blood purifying product, and therefore, a sterile effect can be achieved and materials are less damaged.

Description

technical field [0001] The invention relates to an electron beam sterilization method, in particular to an electron beam sterilization method for blood purification products. Background technique [0002] Sterilization of dialyzer products is a very critical link and a special process in production. Commonly used sterilization methods are: ethylene oxide sterilization, steam sterilization, radiation sterilization and so on. [0003] Sterilized by ethylene oxide, it is a highly reactive substance: Molecular formula: CH 2 -CH 2 -O, flammable and explosive poisonous gas. Sterilization mechanism: ETO can react with the protein of microorganisms, hindering the normal chemical reaction and metabolism of bacterial proteins, resulting in the death of microorganisms, which belongs to chemical sterilization. After sterilization with ethylene oxide, there will be certain residues, and the residues will cause the human body, such as hypotension, coughing, sweating, respiratory syste...
