Abstract

The invention belongs to the technical field of medical disinfectants and relates to a clinical surgical instrument disinfectant. The disinfectant is prepared by adopting the following steps of: getting 100ml of methyl silicone oil and adding 1g of chlorhexidine, 0.5g of polyhexamethylene guanidine and 0.5g of polyvinylpyrrolidone; stirring and dissolving to obtain a methyl silicone oil solution; getting 500ml of water, adding 5g of hypochlorite and 2g of sodium dodecyl sulfate, and stirring and dissolving to obtain an aqueous solution; adding the aqueous solution, the methyl silicone oil solution and 0.5g of polysorbates 80 into a hermetic container; and stirring under ultrasonication and uniformly mixing to obtain an emulsion. The disinfectant has the advantages of stable chemical property, safety, high efficiency and long duration time, and reduces the disinfection number of times of surgical instruments and the probability of surgical infections.

Description

technical field [0001] The invention relates to a disinfectant for clinical surgical instruments, which belongs to the technical field of medical disinfectants. Background technique [0002] The disinfectants currently used are generally water-based disinfectants, which have a short retention time on surgical instruments, which increases the number of disinfections of surgical instruments and at the same time increases the probability of surgical infection. Contents of the invention [0003] In order to overcome the above technical deficiencies, the present invention provides a device with stable chemical properties, safety and high efficiency, and long duration, which can reduce the number of disinfection of surgical instruments and reduce the probability of surgical infection. [0004] The present invention is achieved through the following measures: [0005] The present invention relates to a kind of disinfectant for clinical surgical instrument, it is characterized in...
