Abstract
Abstract A douche apparatus of compact design having a water reservoir or container engaged with a magnetically coupled pump positioned in a housing. The pump is also connected to one end of a flexible tube that is normally stored in the housing. The other end of the tube is connected to a nozzle. The major portion of the tube may be retracted into the housing by a windup mechanism located within the housing and having a handle accessible from outside the housing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
250 words
A douche apparatus comprising: a housing; a reservoir positioned above the housing and resting on a top wall thereof; both said housing and reservoir having aligned passages; valve means coupling between said passages and for controlling liquid flow from said reservoir; pump means contained within said housing below said passages and including a valve actuating means for selectively opening said valve means to deliver liquid to said pump means, and switch means; a flexible tube secured at one end to said pump means and having its other end extending through an opening in said housing to external of said housing and having a syringe nozzle attached to its said other end; an actuating lever disposed adjacent said tube at the tube segment that extends through said opening, said lever operable to change the position of said switch means to operate said pump means and valve actuating means for pumping liquid through said pump means and flexible tube; a storage bin contained within the housing being of a frustoconic shape and having a bottom aperture and a top aperture for accommodating the tube; and a take-up mechanism for engaging a segment of said tube for moving it to and from said storage bin and including; a first pair of pulleys, each having meshing gears associated therewith, arranged coplanar with each other and defining an opening therebetween for gripping said tube, a drive gear engaging with one of said meshing gears, and means external of said housing for rotating said drive gear.
