Abstract

An ostomy appliance having a concave disk insert disposed between the flexible pouch and the faceplate member and designed to reduce the discomfort of prolapse and/or stoma expansion. The invention also includes an ostomy appliance insert for keeping the pressure of clothing from collapsing the ostomy bag against the stoma. The two inserts can most preferably be used in combination to improve comfort of the ostomy appliance user.

Claims

1. In an ostomy appliance comprising a body-side faceplate assembly and a pouch assembly wherein each of said assemblies is provided with a flange member having a coupling member affixed thereto for the coupling of said faceplate assembly and pouch assembly into a single ostomy appliance, the improvement which comprises in combination with said assemblies of a concave disk insert having a circumferential lip portion adapted to be held by and between said coupling rings and having an outer diameter greater than the inner diameter of the smaller of the coupling rings, but less than the outer diameter of the larger of the coupling rings to permit placement of said concave disk between said coupling rings, said concave disk insert having a height such that the disk will not protrude substantially beyond the coupling rings into the ostomy bag, but not so flat as to touch the stoma of the wearer when the stoma is in its normal condition, said concave disk insert provided with a central opening having a diameter in the range of about one-half inch up to about three-fourths of an inch.

2. An improved ostomy appliance in accordance with claim 1 in which the said concave disk insert is provided with a reinforcing ring in surrounding relation to said central opening.

3. An improved ostomy appliance in accordance with claim 2 in which said circumferential lip portion comprises a continuous circumferential ring adapted to lie flat within the plane of junction of said coupling rings and integral with the concave portion of the concave disk insert and in which said concave portions are further provided with openings intermediate said lip portion and said reinforcing ring to improve the ease of cleaning of said concave disk insert.

4. An improved ostomy appliance in accordance with claim 2 in which said circumferential lip portion comprises a plurality of lips in spaced relation to each other around the circumference of said disk insert, said lips adapted to lie within the plane of said junction of said coupling rings and integral with the concave portion of the concave disk insert to provide openings intermediate said lip portion and said reinforcing ring to improve the ease of cleaning of said concave disk insert.

5. In an ostomy appliance comprising a body-side faceplate assembly and a pouch assembly wherein each of said assemblies is provided with a flange member having a coupling member affixed thereto for the coupling of said faceplate assembly and pouch assembly into a single ostomy appliance, the improvement which comprises in combination with said assemblies of a means for holding the exterior wall of said pouch assembly apart from the opening to the stoma of the wearer comprising a semirigid, flexible member having lip portions adapted to be held by and between said coupling rings to permit placement of said member between said coupling rings, said semirigid, flexible member adapted to be placed in an arched position away from the body-side faceplate assembly while being held by and within said coupling of said coupling members, the arch of said arched member having a height substantially greater than the thickness of said coupling.

6. An improved ostomy appliance in accordance with claim 5 in which said arched member comprises a single strip of material comprising a body portion and a lip portion at each end of the body portion adapted to permit the insertion of said lip portions between the coupling rings of said coupling with the body portion of said strip in a generally U-shaped form extending through the coupling ring of said pouch assembly a sufficient distance to urge the exterior wall of said pouch assembly away from said coupling ring.

7. In an ostomy appliance comprising a body-side faceplate assembly and a pouch assembly wherein each of said assemblies is provided with a flange member having a coupling member affixed thereto for the coupling of said faceplate assembly and pouch assembly into a single ostomy appliance, the improvement which comprises in combination with said assemblies of the further combination of (A) a concave disk insert having a circumferential lip portion adapted to be held by and between said coupling rings and having an outer diameter greater than the inner diameter of the smaller of the coupling rings, but less than the outer diameter of the larger of the coupling rings to permit placement of said concave disk between said coupling rings, said concave disk insert having a height such that the disk will not protrude substantially beyond the coupling rings into the ostomy bag, but not so flat as to touch the stoma of the wearer when the stoma is in its normal condition, said concave disk insert provided with a central opening having a diameter in the range of about one-half inch up to about three-fourths of an inch and (B) a means for holding the exterior wall of said pouch assembly apart from the opening to the stoma of the wearer comprising a semirigid, flexible member adapted to be placed in an arched position away from the body-side faceplate assembly while being held by and within said coupling of said coupling members, the arch of said arched member having a height substantially greater than the thickness of said coupling.

8. An improved ostomy appliance in accordance with claim 7 in which the said concave disk insert is provided with a reinforcing ring in surrounding relation to said central opening and in which said circumferential lip portion comprises a plurality of lips in spaced relation to each other around the circumference of said disk insert, said lips adapted to lie within the plane of said junction of said coupling rings and integral with the concave portion of the concave disk insert to provide openings intermediate said lip portion and said reinforcing ring to improve the ease of cleaning of said concave disk insert and in which said arched member comprises a single strip of material comprising a body portion and a lip portion at each end of the body portion adapted to permit the insertion of said lip portions between the coupling rings of said coupling with the body portion of said strip in a generally U-shaped form extending through the coupling ring of said pouch assembly a sufficient distance to urge the exterior wall of said pouch assembly away from said coupling ring, the width of said lip portions of said arched member and the space between the lip portions of said concave disk insert corresponding to permit insertion of said concave disk insert and said arched member into said ostomy appliance with said lip portions lying in generally the same plane corresponding generally to the point of junction of the coupling rings.
