Patent Images
1. A trans-anal irrigation device, comprising:
- an irrigation liquid reservoir;
tubing connected at a first end to the reservoir and in fluid communication therewith;
an irrigation head engageable with the tubing at a second end to provide fluid communication between the tubing and a conduit of the irrigation head,the irrigation head comprising;
a hollow barrel having a wall and at least one port through the wall and in fluid communication with the interior of the barrel, the conduit being disposed in and extending through the barrel, the conduit and barrel wall defining an annulus between an exterior of the conduit and an interior surface of the wall;
a plunger having a hollow shaft, the shaft being sized to fit in the annulus for reciprocal movement therein; and
a balloon surrounding the barrel and having a distal end sealed on one side of the at least one port and a proximal end sealed on the other side of the at least one port.

Abstract
A trans-anal irrigation (TAI) system adapted for self-use includes an irrigation head supplied with water from a reservoir by a pump or by gravity feed. The irrigation head has either internal or external structures for releasably retaining the head in a user'"'"'s rectum during the water flow portion of a TAI process. A guide member arm may be provided for manipulating the irrigation head for both insertion and removal. The irrigation head is reliably attached to the guide member arm. The guide member arm may include an integral manual pump.
