Leakability analysis of disposable gloves

At present, more than half of the health care workers generally believe that hand cleaning after wearing medical disposable gloves, hands will not be contaminated, take off the gloves also do not need to wash their hands. I do not know, although disposable gloves can reduce the degree of contamination of the operator's hands by germs, but does not guarantee that it is free from bacterial contamination, medical disposable gloves material permeability and fine perforation can cause cross-infection between doctors and patients. The permeability of medical disposable gloves mainly comes from two aspects, one is the permeability caused by the disposable glove material's own characteristics, and the other is the perforation caused by external mechanical action, such as sharp medical devices. The next are some introductions.

Self-causes

Microscopically, the rubber material itself has many microscopic pores, and if these pores are larger than the diameter of a bacterial or viral molecule, the latter will penetrate the disposable glove and contaminate the skin or wounds it touches. The permeability of disposable gloves will gradually increase as the use time increases. Research shows that when the medical disposable gloves use timeless than 15min, the glove leakage rate of 29%. When the use of time was more than 15min, the leakage rate rose to 45.1%. Some health care workers even wear a pair of medical hand disposable set of care for more than one patient and will be disposable gloves after washing and reuse, this long time use and cleaning practices, so that the permeability of the glove material increases, more conducive to the transfer of bacteria or viruses.

External causes

Another cause of leakage of disposable gloves is breakage due to external mechanical instruments or being punctured by sharp bone spurs in the body. This phenomenon occurs mostly during surgical procedures, where sharp instruments such as blades, sutures, scissors, and bone fragments are the culprits of damage, and as the duration of surgery increases, the greater the chance of breakage of hospital disposable gloves. According to the literature, about 13.3% to 44.8% of gloves break after surgery, with 20.7% of gloves broken during obstructive surgery and 50% of gloves broken during suturing operations. Breakage sites are commonly found in the index and middle finger areas, and when surgical disposable gloves have an obvious puncture breakage, health care workers can usually detect it in time for replacement. However, for more subtle pinholes, about half of the health care workers tend to find them when the gloves are pressurized with water after surgery. According to relevant studies, a pinhole-sized break in a disposable glove can escape 18,960 Staphylococcus aureus in 20 min, and this germ has been recognized as the most common pathogenic bacteria causing infections in patients. Therefore, whether it is the permeability of the material itself or the leakage of medical gloves caused by external puncture, it will lay a hidden danger to the safety of both doctors and patients. In order to minimize the infection caused by disposable glove leakage, on the one hand, you should choose high-quality medical disposable gloves that meet national quality standards, on the other hand, you should strengthen the frequency of glove replacement and hand cleaning efforts after glove removal, such as the conditions can wear double gloves to enhance protection.
