Enzyme solution, enzyme-containing nonwoven fabric, preparation method and application thereof

Abstract

The invention relates to an enzyme solution. In terms of a total weight of 100wt.%, the enzyme solution comprises: 0.1-10wt.% of a nonionic surfactant, 0.01-1.2wt.% of enzyme, 0.03-10.7wt.% of a room temperature enzyme stabilizer, 1-3wt.% of isothiazolinone, 0.1-1wt.% of benzisothiazolinone, 0.1-1wt% of sodium benzoate, 0.2-0.5wt% of a chelating agent, 6.9-10wt% of a solubilizer, 0.15-0.5wt% of a pH regulator, and 63-81wt% of water. The enzyme solution disclosed by the invention has good cleaning ability; secondly, the enzyme solution has good compatibility with nonwoven fabric containing viscose fiber and polyester fiber, the enzyme solution scattered in the nonwoven fabric not only has good enzyme stability, but also has good anti-mildew and antibacterial performance. In addition, the enzyme containing non-woven fabric disclosed by the invention is not easy to cause damage to medical equipment, and is also not easy to corrode metal or rubber parts of medical equipment.

Description

technical field [0001] The disclosure relates to the field of cleaning and disinfection, in particular to an enzyme solution, an enzyme-containing non-woven fabric and a preparation method and application thereof. Background technique [0002] Cleaning and disinfection (or sterilization) are key steps in the post-use treatment of medical devices. For heavily contaminated devices, pre-cleaning or pre-cleaning steps can significantly improve the success rate of subsequent cleaning and disinfection, prolong the service life of medical devices, and reduce the risk of infection. For example, in a hospital, when a doctor removes an endoscope from a patient, immediately before detaching the endoscope from the light source or video processor, wipes the outer surface of the endoscope with a cleaning solution or damp gauze to remove contamination from the outer surface of the endoscope to complete the pre-cleaning of the endoscope. [0003] At present, most hospitals use traditional...

AI Technical Summary

Problems solved by technology

However, the poor stability of the enzyme in the diluted enzyme solution may lead to a decrease in the success rate of pre-cleaning; in addition, the traditional gauze has poor compatibility with the enzyme solution, and after the enzyme solution is dispersed in the traditional gauze, the enzyme activity drops off quickly, which may also affect the success rate of pre-cleaning
