ABSTRACT:
An automated endoscope reprocessor (10) includes a removable rack (12) for receiving a container (16, 16′). The container has a clamshell housing (20) having two mating portions (24, 26). The portions together define an internal pressurizable chamber (56) for receiving an endoscope head (22). The endoscope's connector cord (82) is carried through an outlet (80) to the chamber. The outlet is defined by channels (88, 90), one in each of the two housing portions (24, 26). A gasket assembly in the outlet provides a restricted fluid passage which allows a small portion of fluid to flow through the outlet when the connector cord is positioned therein. The gasket assembly (120) includes a number of resiliently flexible fins (126, 128, 130) positioned in each channel, each fin having a U-shaped slot (144, 146, 148). Pairs of fins overlap such that the slots together define openings (150) of diminishing size. Depending on the diameter of the cord, the cord is contacted by one or more of the fins adjacent the respective slot. A reprocessing liquid, such as peracetic acid in solution, is pumped into the chamber (56). The liquid leaks slowly through the slots, allowing an above ambient pressure to be maintained in the chamber, while ensuring that all exterior surfaces of the endoscope are contacted with the reprocessing liquid.
