Medical packaging material resisting impregnation

Abstract

The invention relates to a medical packing material resisting impregnation, which comprises a surface layer and a bottom layer, wherein the surface layer is arranged above the bottom layer, contents are arranged between the surface layer and the bottom layer, the bottom layer comprises dialyzing paper and an impregnation resisting layer, the impregnation resisting layer is arranged on the outer side of the bottom layer, the dialyzing paper is arranged on the inner side of the bottom layer, and the dialyzing paper is directly contacted with the contents. In the medical packaging material resisting impregnation provided by the invention, the impregnation resisting layer is arranged at the bottom layer, so that liquids, such as blood, alcohol, distilled water and the like which are usually used in medical environments, can be prevented for impregnating, and sterilized medical instruments can be prevented from being contaminated. The impregnation resisting layer provided by the invention can ensure the air permeability of the bottom layer, and meets requirements on air permeability indexes in related standards.

Description

technical field [0001] The invention relates to a packaging material, in particular to a medical packaging material, which can withstand liquid immersion such as blood, alcohol, and distilled water. Background technique [0002] Medical packaging materials generally require sterilization. The sterilized packaging material forms a microbial isolation barrier outside the medical device, so that the medical device will not be contaminated by external microorganisms within a certain period of time, ensuring that the medical device is relatively sterile before use. If the sterilized packaging material has a poor barrier effect on microorganisms, the packaged medical devices are easily contaminated by external pathogenic microorganisms after sterilization, which can lead to wound infection of patients in mild cases, and endanger the lives of patients in severe cases. Therefore, rational use of medical packaging materials is one of the most effective ways to control hospital infec...

Problems solved by technology

[0005] In the actual use process, although the paper-plastic packaging bag has been sterilized, due to the influence of the use environment, the surface layer 20 and the bottom layer 30 of the paper-plastic packaging bag often splash some blood, alcohol, distilled water and other liquids, and are affected by blood. , alcohol, distilled water, etc., especially blood, alcohol, distilled water, etc. are immersed into the inner side of the bottom layer 30, which will cause the contents of the inner package to be polluted, and can not meet the relatively sterile medical requirements
