摘要

A closed system, i.e., apparatus for automatically decontaminating various articles, including hollow bags and tubing, by washing and disinfecting them with a liquid chemical disinfectant, using the same tub for both washing and disinfection. The articles are automatically agitated in the washing and disinfecting liquids to loosen dirt and assure complete wetting of their inside and outside surface by the disinfectant. Containers are provided for mounting the hollow articles for agitation and spinning from the same shaft, preferably in baskets provided for this purpose, and for holding them in positions which will assure their thorough washing, disinfecting and emptying. A unique storage and transfer system is employed for the disinfectant supply and this includes a novel diverter or transfer valve for connecting to the tub drainage system. The apparatus preferably uses a disinfectant supply which has a relatively long life and is used over and over again in successive decontaminating cycles and has a use cycle timing device for rendering the apparatus inoperative at the end of a given use cycle for the disinfectant. A device is provided for again rendering the apparatus operative after a new supply of disinfectant is substituted for the old. Various other timing and control features are provided.
