Locating flange for a two-piece ostomy adhesive mount

This application claims the benefit of U.S. Provisional Application No. 61/057,391, filed on May 30, 2008, the entire disclosure of which is hereby incorporated herein by reference.

1. Field of the Invention

This invention relates to a two-piece mounting assembly for an ostomy pouch and, more particularly, to a locating arrangement for an adhesively coupled two-piece mounting assembly. The assembly includes a body flange piece which is adhesively bonded to the peristomal skin surfaces of an osteomate. A pouch is in turn adhesively bonded to the body flange piece. The arrangement allows the osteomate to change bags several times without removing the body flange piece.

2. Brief Description of the Invention

This invention provides a convenient interlock between the body flange piece and the pouch so that these units may be properly aligned prior to bonding. The interlock includes diametrically arranged loops on the body flange and corresponding diametrically aligned loops on the pouch. One set of diametrically aligned loops is provided with pockets on one face and another set of diametrically aligned loops is dimentioned to fit within the pockets to provide the interlock. When the loops are snapped together, pressure may be applied to the adhesive interface between the body flange and the pouch to secure these members.

An ostomy belt may be employed as added security to hold the mounting assembly in place. Clips on the belt pass through the aligned loops to retain the assembly as a unit.

FIG. 2 is a sectional view, the plane of the section being indicated by the line 2 - 2 in FIG. 1 ;

FIG. 3 is a bottom view of the mounting flange;

FIG. 4 is a view of a pouch; and;

FIG. 5 is a sectional view, the plane of the view. Being indicated by the line 5 - 5 in FIG. 4 .

Referring to FIGS. 1-3 , there is illustrated a body flange 10 adapted to be affixed to the peristonal skin surface and surround the stoma S of an osteomate. The flange 10 comprises a stiffly flexible plastic base portion 12 having a rim 14 and a central dome 16 , as may be seen in FIG. 2 . A ring 19 projects from the dome bottom.

An adhesive layer 18 covers the top of the flange 10 and is preferably a hydrocolloid-containing adhesive capable of absorbing moisture and having both wet and dry tack. A release liner 20 covers the layer 18 and has a tab 21 permitting ease of removal. A foam layer 22 is interposed between the adhesive layer 18 and the flange 10 .

The flange 10 further includes diametrically opposed first and second loops 24 and 25 . Each loop is provided with a fence 26 which forms a pocket 28 on the loops 24 and 25 .

Referring now to FIGS. 4 and 5 , there is illustrated a pouch 30 formed by inner and outer plastic walls 32 and 34 respectively. The walls 32 and 34 are sealed at their edges to form a stoma receiving pouch. An aperture 36 is provided in the wall 32 and a stiffly flexible plastic ring 38 surrounds the aperture 36 .

The ring 38 is provided with a central groove 39 and a pair of diametrically opposed ring tabs 41 and 43 surrounds the aperture. An adhesive coating 40 covers the ring 38 and the coating, in turn, is covered by a release liner 42 .

With the flange 10 in place on the skin of the osteomate and with the liner 42 on the adhesive 40 removed, the third and fourth loops 41 and 43 are grasped and the third and fourth loops 41 and 43 are snapped into the pockets 28 . When the third and fourth loops 41 and 43 are in place, the ring 19 is aligned with the groove 39 and will enter the groove 39 . When the body flange 10 needs to be replaced, it may be peeled off by grasping a tab 42 a ( FIG. 4 ).
