Locating flange for a two-piece ostomy adhesive mount

A mounting assembly for an ostomy pouch. The assembly includes a body flange having an adhesive coating on one side adapted to be adhered to the peristomal skin surface of an osteomate. Diametrically opposed loops project from the edge of the flange and form pockets. Also included is an ostomy pouch having a stoma receiving opening surrounded by a stiffly flexible ring having diametrically opposed loops that cooperate with the pockets on the flange loops. An adhesive coating is provided on the flexible ring and there is a mechanical interlock between the ring and flange. When the loops on the flexible ring are aligned with the pockets on the flange the flange and ring may be adhesively interlocked to attach the pouch to the body flange.

BACKGROUND OF THE INVENTION

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.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring toFIGS. 1-3, there is illustrated a body flange10adapted to be affixed to the peristonal skin surface and surround the stoma S of an osteomate. The flange10comprises a stiffly flexible plastic base portion12having a rim14and a central dome16, as may be seen inFIG. 2. A ring19projects from the dome bottom.

An adhesive layer18covers the top of the flange10and is preferably a hydrocolloid-containing adhesive capable of absorbing moisture and having both wet and dry tack. A release liner20covers the layer18and has a tab21permitting ease of removal. A foam layer22is interposed between the adhesive layer18and the flange10.

The flange10further includes diametrically opposed first and second loops24and25. Each loop is provided with a fence26which forms a pocket28on the loops24and25.

Referring now toFIGS. 4 and 5, there is illustrated a pouch30formed by inner and outer plastic walls32and34respectively. The walls32and34are sealed at their edges to form a stoma receiving pouch. An aperture36is provided in the wall32and a stiffly flexible plastic ring38surrounds the aperture36.

The ring38is provided with a central groove39and a pair of diametrically opposed ring tabs41and43surrounds the aperture. An adhesive coating40covers the ring38and the coating, in turn, is covered by a release liner42.

With the flange10in place on the skin of the osteomate and with the liner42on the adhesive40removed, the third and fourth loops41and43are grasped and the third and fourth loops41and43are snapped into the pockets28. When the third and fourth loops41and43are in place, the ring19is aligned with the groove39and will enter the groove39. When the body flange10needs to be replaced, it may be peeled off by grasping a tab42a(FIG. 4).
