Abstract

The invention discloses a disinfectant suitable for endoscope disinfection and sterilization. The disinfectant is characterized in that the disinfectant comprises, by weight, 30-40 parts of peroxide,15-25 parts of an acylating agent, 12-22 parts of a buffering agent and 2-18 parts of an anionic surfactant. After 1 part by weight of the disinfectant is dissolved in 20-300 parts by weight of water,an obtained disinfection and sterilization solution contains 500-10000 mg/L peroxyacid ions, and the pH of an aqueous solution of the disinfection and sterilization solution is 5-9. The pH of the disinfectant of the invention is weakly alkaline to weakly acidic, which has little corrosivity to medical instruments and especially is not prone to the damage to an endoscope. The disinfectant of the invention has good compatibility with various components of the endoscope, including a handle, a handle connection part, a button, a sealing ring, bending rubber, an insertion tube sleeve, a light guide cable insertion part and a plastic tube, is not prone to the corrosion, air leakage, aging and other damages of the endoscope, and is especially suitable for the disinfection and the sterilization of the endoscope.

Description

technical field [0001] The invention relates to the technical field of chemical disinfectants, in particular to a disinfectant suitable for endoscope disinfection and sterilization. Background technique [0002] Endoscopic diagnosis and treatment have been popularized and widely used in clinical practice. However, due to the fine structure and special materials of endoscopes, many parts are not resistant to high temperature, fear of corrosion, high cost, and frequent use and turnover, etc., it brings many difficulties to endoscope disinfection and sterilization. , is an important way to cause iatrogenic transmission of hospital cross-infection. The existing iatrogenic infections caused by endoscopy include: Salmonella, Pseudomonas aeruginosa, Mycobacterium, HBV, HCV, HIV, Helicobacter pylori, Serratia marcescens, Staphylococcus epidermidis, Enterobacter, white hair sporozoites, roundworms, herpes simplex virus, etc. Therefore, it is imperative to strengthen the management ...
