Abstract

Ostomy appliance for attachment around an aperture or opening of the human body including a first member having an adhesive plate fixably positionable by adhesion around the aperture of the human body, a first flange having an annular or ring-form fitting portion around an aperture extending through the adhesive plate, the first flange having a collar or tab extending outwardly from at least a portion of the fitting portion thereof, the collar or tab forming at least one cut-away recess or notch or truncated portion extending to the outermost peripheral edge of the fitting portion, a second member having a second flange with an annular or ring-form fitting portion cooperatively engageable with the first fitting portion, the second member having a bag portion or a cap portion associated with the side thereof opposite the second fitting portion, the cut-away recess or notch being of such a size as to enable the insertion of a finger therein for guiding the first and second members into engagement with each other.

Claims

1. Ostomy appliance comprising an adhesive plate fixably positionable by adhesion around the aperture of a human body, a first flange attached to the non-adhesive side of said adhesive plate, and a second flange capable of fitting to said first flange,

said adhesive plate having an opening corresponding to the aperture of the human body,

said first flange being fixed to said adhesive plate and extending outwardly nearly along the surface of said adhesive plate, said first flange having a ring-form fitting portion on the side opposite to said adhesive plate and extending around the opening of said adhesive plate, said ring-form fitting portion having an outermost periphery extending therearound and around said opening, a collar portion extending around at least one portion of the ring-form fitting portion, said collar portion have a cut-away recess in at least a portion thereof, said cut-away recess reaching the outermost periphery of said fitting portion and being of sufficient size as to allow a finger to be inserted therein, and

said second flange having a ring-form fitting portion on one side thereof engageable with the fitting portion of said first flange, said cut-away recess being positioned so as to enable placement of a finger against the outermost periphery of the fitting portion of said first flange to enable aligning said fitting portions for engagement.

2. The ostomy appliance of claim 1 wherein the second flange has an ostomy bag attached thereto.

3. The ostomy appliance of claim 1 wherein the second flange has a cap attached thereto.

4. An ostomy appliance comprising first and second members, said first member including an adhesive plate having opposite first and second surfaces and an aperture extending therethrough, the first surface being adhesively fixable to a human body around an opening therein, the aperture extending through the adhesive plate corresponding approximately in size to the opening in the human body,

a flange attached to said adhesive plate around the aperture extending therethrough, said flange extending outwardly from the aperture adjacent the second surface of said adhesive plate, said flange having first annular fitting means extending around the aperture opposite said adhesive plate, the first annular fitting means having a first outer peripheral edge extending therearound and around said aperture, the flange having a collar extending outwardly from one or more portions of the first outer peripheral edge, the collar forming at least one notch extending inwardly to adjacent the first outer peripheral edge, the notch being sufficiently large to enable a finger to be positioned therein adjacent to the first outer peripheral edge, and

said second member having second annular fitting means cooperatively and sealably engageable with the first annular fitting means for detachably fitting the second member to the first member, the second annular fitting means having a second outer peripheral edge, said notch being positioned to enable a finger positioned therein to be used to align the first and second outer peripheral edges for cooperatively engaging the first and second annular fitting means, said notch being further positioned to enable movement of the finger without leaving the fitting means to a position between said adhesive plate and said flange to enable the finger to be used to facilitate engagement of the fitting means.

5. The ostomy appliance of claim 4 wherein said second member includes on ostomy bag.

6. The ostomy appliance of claim 4 wherein said second member includes a cap.

7. The ostomy appliance of claim 4 wherein the notch has a substantially linear shape.

8. The ostomy appliance of claim 4 wherein the collar forms a pair of opposing substantially linearly shaped notches.

9. The ostomy appliance of claim 4 wherein the second outer peripheral edge is dimensioned to correspond approximately to the size of the first outer peripheral edge.

10. The ostomy appliance of claim 4 wherein the flange is attached to the adhesive plate by an annular member.

11. An ostomy appliance comprising a first member including an adhesive plate having first and second opposed surfaces, the first surface being fixable by adhesion to a human body around an opening therein, and an aperture extending through said adhesive plate corresponding in size to an opening in an human body,

a first flange attached to said adhesive plate around the aperture extending therethrough, said first flange extending radially outwardly relative to the aperture along said second surface, said first flange having first annular fitting means extending around the aperture opposite said adhesive plate and a first outer peripheral edge extending round the annular fitting means, a tab extending outwardly from a portion of the first outer peripheral edge, the tab having at least one truncated portion abutting the first outer peripheral edge,

a second member having a second flange with second annular fitting means thereon and a second outer peripheral edge therearound, said second annular fitting means being cooperatively engageble with the first annular fitting means for detachably fitting the first and second members together, said truncated portion being of such a size to enable a finger to be positionable therein against the first and second members to guide the members into engagement with each other.

12. An ostomy appliance having a first member for attaching to the skin of a patient, said first member having an aperture therethrough and an annular flange portion extending around said aperture, said annular flange portion having an outer peripheral edge extending therearound and around said aperture, a portion extending outwardly from said annular flange adjacent one side thereof for attaching to the skin of the patient, and a bag member having an attachment portion including an annular flange portion for matingly engaging the annular flange portion on the first member when the respective annular flange portions are pressed together, the improvements comprising means for aligning by feel the annular flange portion of the bag member with the annular flange portion on the first member to facilitate engagement of the respective flange portions, said alignment means including a collar extending around at least a portion of the outer peripheral edge of said annular flange portion, said collar having a cut-out portion extending to the outer peripheral edge of the annular flange portion on the first member said cut-out portion being sufficiently large to enable insertion of a finger therein for aligning the respective edges of the annular flange portions on the first member and on the bag member.
