Abstract
An expandable cuff assembly encloses a circular opening in the front panel of a lavage machine. The opening is made large enought to permit arms of a user to be inserted freely through the opening. After this is done, the expandable cuff member is filled with air to cause it to expands from a first state, having an enlarged opening through it, to a second state where it resiliently closes against the arm of the user to prevent liquid from splashing out of the lavage machine during use. After the operation of the machine is completed, the expandable cuff member returns to its first state, with a large opening therethrough to permit withdrawal of the arms of the user freely through the enlarged opening.
