Glass fibre endoscope rinsing and disinfecting - using polyvinyl pyrrolidone-iodine soln. for intermediate disinfection and glutaric di:aldehyde soln. for final step

摘要

Glass fibre endoscopes are rinsed and disinfected in an apparatus comprising a container for rinsing liq., esp. water, and a 2nd container for disinfectant compsn. The containers are linked to conduits which can be connected alternatingly to an endoscope conduit via a control element. The glass fibre endoscopes are quickly disinfected with a disinfectant compsn. between intermediate individual uses and subjected to a long disinfection on completing the use. For intermediate disinfection, a pref. soln. contains polyvinyl pyrrolidone. I2, esp. in mixing ratio 50 % polyvinyl pyrrolidone. I2, 25% water and 25% of 70% EtOH. A disinfectant soln. for main disinfection consists of a 2% glutaric dialdehyde soln. activated with Na2CO2.
