Abstract:
Objective To evaluate the performance of the disposable medical protective clothing in blocking the penetration of infectious agents,in order to provide data support for the setting of such performance indexes when the GB 19082 is revised.Methods Totally 10 batches of different brands and models of protective clothing were selected,and tests were carried out for penetration resistance to synthetic blood,phage,wet microorganisms,dry microorganisms and contaminated liquid aerosol and particle filtration efficiency according to YY/T 0700-2008,YY/T 0689-2008,YY/T 0506.6-2009,GB 19082-2009,YY/T 0506.5-2009 and YY/T 1799-2020.Results There were 2 batches of protective clothing with anti-synthetic blood penetration performance level 2,3,4,5 and 6,respectively;all the protective clothing had the highest level 6 for anti-wet microorganisms penetration,part of whom had the levels for the resistance to phage penetration lower than those for preventing anti-synthetic blood penetration;all of the protective clothing had the particle filtration efficiencies higher than 95％,and had the highest level 3 for anti-dry microorganisms penetration;there're 5 batches of protective clothing with the highest level 3 for contaminated liquid aerosol penetration,1 batch with level 2 and the remained 4 batches with undetermined levels,which all had an average logarithmic reduction higher than 4.5 after penetration.Conclusion Particle filtration efficiency and resistance to phage penetration may be involved in the requirements for resistance to infective agent penetration in revised GB 19082 for evaluating the ability of protective clothing materials to block microorganisms in airborne particles and liquid contaminants.[Chinese Medical Equipment Journal,2024,45(5):16-21]
