Abstract

An ostomy device for holding the neck of a drainage sleeve in operative association with a body opening such as for collecting fluids draining outwardly through the body opening. The device is formed as a one-piece gasket arranged to clamp the sleeve neck upon arrangement of different portions of the device in clamping association with an out-turned portion of the sleeve neck clamped therebetween. The device is arranged to be retained on the user'"'"'s body by affixation of a belt or the like and includes structure for removable connection of the belt thereto.

Claims

1. In an ostomy device having a drainage sleeve provided with a flexible connecting neck defining an inlet opening, improved retaining means for use in retaining the sleeve neck to a user'"'"'s body in alignment with a stoma therein for collecting material draining outwardly through the stoma, said retaining means comprising:

a one-piece gasket having a first inner clamp half provided with a first drain opening, a second outer clamp half provided with a second drain opening, a hinge comprising portions of said clamp halves connecting the clamp halves for selective spaced disposition and facially overlying clamping disposition with said drain openings aligned, cooperating means on said clamp halves for sealingly securing said sleeve neck between said clamp halves in said clamping disposition with said neck passed through said second drain opening of the outer clamp half and outturned between said clamp halves with said inlet opening aligned with said first drain opening of the inner clamp half, and at least two different types of releasable interlock means for releasably interlocking said clamp halves in said clamping disposition; and

means for preventing disengagement of said interlock means when the device is being retained to the user'"'"'s body.

2. The ostomy device of claim 1 wherein said interlock means includes means acting between said clamp halves and engaging said outturned neck for effectively positively securing said neck between said clamp halves.

3. The ostomy device of claim 1 wherein said interlock means includes a projection on one of said clamp halves and a mounting recess on the other of said clamp halves.

4. The ostomy device of claim 1 wherein said interlock means includes a projection on one of said clamp halves at the edge of the drain opening thereof extending into the drain opening of the other clamp half when the clamp halves are in said clamping disposition.

5. The ostomy device of claim 1 wherein said interlock means includes a turned projection on one of said clamp halves at the edge of the drain opening thereof extending into the drain opening of the other clamp half when the clamp halves are in said clamping disposition and snapped laterally outwardly to overlie the edge of the other of said clamp halves defining the drain opening thereof.

6. The ostomy device of claim 1 wherein said interlock means includes a turned projection on one of said clamp halves at the edge of the drain opening thereof extending into the drain opening of the other clamp half when the clamp halves are in said clamping disposition and snapped laterally outwardly to overlie the edge of the other of said clamp halves defining the drain opening thereof, said edge of the other clamp half defining a projection extending away from said one clamp half.

7. The ostomy device of claim 1 wherein said interlock means includes a turned projection on one of said clamp halves at the edge of the drain opening thereof extending into the drain opening of the other clamp half when the clamp halves are in said clamping disposition and snapped laterally outwardly to overlie the edge of the other of said clamp halves defining the drain opening thereof, said edge of the other clamp half defining a projection extending away from said one clamp half and said turned projection of the one clamp half including a distal portion turned back toward said one clamp half, said sleeve neck being captured between said projections for effective positive locked retention therebetween.

8. The ostomy device of claim 1 wherein said means for preventing disengagement of the interlock means comprises holding means for releasably holding the assembled gasket with said drainage sleeve sealingly mounted thereto in position on the user'"'"'s body to collect in said sleeve material passed outwardly through said stoma, said holding means defining means for holding the first clamp half against the user'"'"'s body surrounding said stoma.

9. The ostomy device of claim 8 wherein said holding means includes belt attachment openings in each of said clamp halves which are aligned when the clamp halves are in the clamping disposition, and belt means including connecting portions extended through said aligned openings.

10. The ostomy device of claim 8 wherein said holding means further defines means looped through said clamp halves for retaining said clamp halves in the clamping disposition.

11. The ostomy device of claim 8 wherein said holding means comprise means spaced at opposite sides of said hinge.
