Abstract: Objective To observe the disinfection effect and continuous use stability of phthalaldehyde endoscope. Methods Carrier quantitative germicidal test and simulation
The disinfection test method was used to observe the effect of phthalaldehyde disinfection endoscopes. Results With a concentration of 3 000 mg /L o-phthalaldehyde disinfection solution, in the clear
The total running time of the washing and disinfecting machine setting program is 25. 5 min, or the whole process of manual cleaning is 18. 5 min, which is contaminated with Bacillus subtilis black on the carrier of the simulated digestive endoscope.
The average elimination logarithm of spores in the color varieties was> 4. 0. Under the simulated operating conditions of the cleaning and disinfecting machine, 81 gastroscopes were treated with continuous use for 14 d and cumulative disinfection.
The content of phthalaldehyde decreased from 5 880 mg /L to 3 960 mg /L, and the liquid-treated bacteria-infected simulated endoscope body still met the disinfection requirements. Conclusion The phthalate
Under simulated field conditions, the aldehyde disinfectant can meet the specified disinfection requirements regardless of whether it is handled by the disinfection machine or by hand, with a total of 81 stomachs in the operation of the disinfection machine.
mirror, o-phthalaldehyde disinfectant remains in the effective concentration range.
