US 7,001,367 B2 · Valved ostomy drainage device

Abstract

The valved ostomy drainage device of the present invention includes a primary conduit which may be inserted into either a colonoscopy or ileostomy. Once inserted, a balloon cuff or collar on the inner aspect of the conduit is inflated which holds the conduit in place in the ostomy. The conduit is anchored on the exterior surface of the patient by a soft, malleable ring which acts as a resilient pad seal and by an anchoring collar which mounts onto the exposed end of the conduit to sandwich the ring against the patient's abdomen. With the collar so mounted the remaining exposed end of the conduit is adapted for sealing by the releasable mounting thereon of a rigid sealing member such as a threaded cap or other means of closure. A flexible one-way valve mounted in the conduit inhibits waste such as bowel contents or stool extruding through the conduit until the cap is removed and the one-way valve biased open by a secondary conduit inserted into the primary conduit and pushed against the one-way valve so as to open the valve.

Dependent claims

A valved ostomy drainage device comprising:

hollow first and second conduits, said first conduit having first and second opposite ends, said first end having an inflatable annular anchor mounted thereto for selective inflation so as to anchor said first end with a patient's bowel ostomy behind the abdominal wall of the patient, and wherein said second end is cylindrical and externally threaded and said first conduit is of sufficient length so that, with said anchor inflated and snug against the interior surface of the abdominal wall, a portion of said second end protrudes from the stoma,
wherein a threaded first collar is mountable onto said second end of said first conduit so that, once snugged adjacent the exterior surface of the abdomen, said inflated anchor is held snugly against the abdominal wall, and wherein, with said first collar so mounted, a length of said second end of said first conduit protrudes from said first collar, a sealing means mountable onto said second end of said first conduit to provide a removable and re-usable fluid and gas seal on said second end of said first conduit, and wherein a one-way valve is mounted in said first conduit.

A valved ostomy drainage device comprising a primary conduit for journalled mounting through an ostomy aperture in an abdomen, said primary conduit having an inner end for protrusion through the aperture, on the inner wall of abdomen, and an opposite outer end for protrusion outwardly of the aperture from the outer wall of the abdomen,

an inflatable cuff mounted around said inner end of said primary conduit, said primary conduit having inflation means in fluid communication between said outer end and said cuff for inflation of said cuff when adjacent the inner wall of the abdomen,
an anchoring collar releasably mountable onto said outer end of said primary conduit so as to sandwich the abdomen between said cuff, when inflated, and said anchoring collar,
a releasably mountable end seal mountable onto said outer end for releasably sealing said outer end,
a secondary conduit sized for mounting a first end thereof into and along said primary conduit, an opposite second end of said secondary conduit adapted for mounting of a waste container thereto,
a one-way valve mounted in said primary conduit for preventing flow of waste in an outflow direction from said inner end to said outer end and for allowing said secondary conduit to be inserted through said one-way valve from said outer end of said primary conduit whereby waste then flows in said outflow direction through said secondary conduit.
