Transanal irrigation kit
First Claim
Patent Images
1. An anal irrigation kit, comprising:
- an irrigation liquid reservoir;
a pump in fluid communication with the irrigation liquid reservoir; and
a flow manifold in fluid communication with the pump, the flow manifold including multiple openings, wherein the flow manifold is made of a soft, resilient polymeric material, such that the flow manifold is sufficiently stiff to be pushed through an anal canal and self-deployable once in a rectum, but soft enough to be manually foldable for insertion into the rectum;
the flow manifold further includes a distalmost flared-end portion including a flared wall with an outer surface area configured to sealingly engage the rectum as fluid flows through the flow manifold and a cover portion attached to a distalmost flared edge of the flared wall,wherein a flow lumen is defined by an enclosed inner surface area of the flared-end portion between the flared wall and the cover portion and a plurality of the multiple openings are arranged about the distalmost flared edge of the flared wall in fluid communication with the flow lumenwherein the irrigation liquid reservoir has an inlet, an inner wall and an outer wall, the inner wall and the outer wall being sealed together along peripheral edges to define a cavity; and
the pump is a hand pump including a rigid outer wall, a top inlet and a bottom outlet; and
the flow manifold has an entry end proximate the hand pump.

11. A handheld transanal irrigation kit having a proximal end and a distal end comprising:
-
an irrigation liquid reservoir, the irrigation liquid reservoir having an inlet, a first wall and a second wall, the first wall and the second wall are sealed together along peripheral edges to define a cavity; a hand pump, the hand pump including a rigid outer wall, a top inlet and a bottom outlet, and having a first one-way valve located proximate the top inlet and having a second one-way valve located proximate the bottom outlet; a resilient flow manifold, the flow manifold being constructed of a resilient material, the flow manifold having a flow lumen therethrough, the flow manifold having an entry end proximate the hand pump and a distalmost exit end, the distalmost exit end having a flared-end portion including a flared wall with an outer surface area configured to sealingly engage a rectum as fluid flows through the flow manifold and a cover portion attached to a distalmost flared edge of the flared wall, wherein a flow lumen is defined by an enclosed inner surface area of the flared-end portion between the flared wall and the cover portion and a plurality of openings are arranged about the distalmost flared edge of the flared wall in fluid communication with the flow lumen.

12. A method of emptying a bowel, comprising the steps of:
-
providing an anal irrigation kit including an irrigation liquid reservoir, a hand pump, and a soft flow manifold including multiple openings, the soft flow manifold further including a distalmost flared-end portion including a flared wall with an outer surface area configured to sealingly engage a rectum as fluid flows through the flow manifold and a cover portion attached to a distalmost flared edge of the flared wall, wherein a flow lumen is defined by an enclosed inner surface area of the flared-end portion between the flared wall and the cover portion and a plurality of the multiple openings are arranged about the distalmost flared edge of the flared wall in fluid communication with the flow lumen; folding the soft flow manifold and inserting the folded soft flow manifold into the rectum; and instilling an irrigation liquid and stimulating a rectal wall simultaneously by operation of the hand pump. - View Dependent Claims (13, 14, 15, 16)
