Embodiment 1

[0026] For medical disposable protective clothing that has just been prepared and has not been sterilized and analyzed (the model is the "Bangkai" brand protective clothing produced by Bangwei Company, model S8, a total of 3 batches, respectively marked as A1, A2, A3) According to the method recorded in GB 19082-2009, the liquid barrier function (water permeability resistance, synthetic blood penetration resistance, breaking strength, breaking elongation and filtration efficiency) test is carried out. The test results are shown in Table 1 below.

[0027] Table 1

[0028]

[0029] The above-mentioned medical disposable protective clothing is sterilized. The specific operation process is: place the medical disposable protective clothing in an atmosphere with an ethylene oxide concentration of 400-1000mg / L, and act for 24 hours at 20-60°C within 4 times after the completion of EO treatment (i.e. sterilization treatment) to complete the analysis process, and when the number of...

Abstract

The invention belongs to the technical field of preparation of hygienic products, and particularly relates to a method for performing efficient sterilization and intensive analysis on medical protective articles by using ethylene oxide. According to the sterilization method disclosed by the invention, sterilization is performed by utilizing the ethylene oxide of a certain concentration and with the cooperation of multiple times of nitrogen replacement, and accordingly, the one-day sterilization effect and ethylene oxide residues can meet the requirements of medical protective articles under the optimal condition, and the national standard regulation is met. When emergency epidemic situations occur, such as the breakout of the corona virus disease 2019, sterilization can be rapidly and efficiently achieved, and protective articles meeting medical requirements are prepared.

Description

technical field [0001] The invention belongs to the technical field of preparation of hygiene articles, and in particular relates to a method for efficiently sterilizing and strengthening analysis of medical protective articles by using ethylene oxide. Background technique [0002] Since the discovery and recognition of HIV (AIDS virus) and HBV (hepatitis B virus) in the 20th century, the risk of infection of medical workers in the process of treating patients has attracted more and more attention, especially in 2003 when SARS (commonly known as atypical In a major outbreak of pneumonia), medical workers were repeatedly infected. Although the final temporary victory, it also made people realize the importance and serious shortage of self-protection of medical workers and high-risk groups. Since the emergence of viruses transmitted through blood or body fluids or even aerosols, countries have begun to focus on the development of medical protective equipment such as medical st...
