Abstract

The invention discloses a medical instrument disinfectant. The medical instrument disinfectant is prepared from, by weight, 1-2 parts of dibromohydantoin, 1.6-3.8 parts of paraformaldehyde, 11-15 parts of chervil larkspur herb, 7-13 parts of a disinfecting drug, 8-12 parts of folium baeckeae, 6-8 parts of leaves of eucalyptus tereticornis, 4-7 parts of whiteflower cacalia seeds, 2.2-3.8 parts of ethylene oxide, 2-3 parts of Gemini quaternary ammonium salt and 0.5-1.5 parts of chlorinated sodium phosphate. The medical instrument disinfectant has the advantages that multiple Chinese herbal medicines with the higher antibacterial effect are screened out for reasonable compatibility, and then the disinfectant which is capable of quickly killing bacteria, wide in antibacterial spectrum, long in bacteriostatic time and the like is prepared; the prepared disinfectant is good in disinfection effect, capable of quickly killing pathogenic bacteria on an instrument, free of corrosive action on the equipment, stable in performance and long in quality guarantee period.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a medical instrument disinfectant and a preparation method. Background technique [0002] Today's medical industry is developing rapidly, and the requirements for medical equipment and hospital safety are getting higher and higher. Medical devices must undergo standardized cleaning and disinfection work and be handled by specific professionals. Whether medical equipment is safe and pollution-free is related to whether the life safety of hospital staff and patients can be guaranteed, and it is an important link to ensure medical safety. [0003] Many medical devices are seriously polluted after use, even with pus, blood, and dried secretions. If they are not handled properly and not in time, it is easy to spread the source of pollution and have a huge impact on medical safety. If the used medical devices are not cleaned thoroughly, a vicious cycle will occur: (1) organic residues after cleaning...
