Abstract
An improved apparatus which can be used for cleaning and/or sterilizing tubular items. A container is partitioned into two chambers with the item to be cleaned and/or sterilized is positioned to extend through the partition such that one opening lies in one chamber and another opening lies in the other chamber. A flexible membrane is positioned to affect each chamber. By deforming the flexible membrane, inward and outward, a flow between the chambers is created. This flow must pass through the hollow item. Mechanical pressure from the flow cleanses the interior of the tubular item and if a sterilant is used as the medium, then the interior portion of the hollow item is also sterilized.
