Ostomy bag with a compacted sheath

Abstract

There is provided a disposable ostomy bag assembly (1) comprising a bag (3) for receiving bodily waste materials; a compactable sheath (2) for closing and sealing the bag (3) after use; and a flange (4) for securing the assembly to the body of a patent and provided with an orifice to enable bodily waste to be received by the bag (3). The ostomy assembly (1) solves the problem of escaping malodor and bodily waste when the patient detaches the ostomy bag from the body (face plate (5)). The compactable sheath (2) can be stretched to acquire a cylindrical sheath (2) extending from the flange (4), whereby the sheath (2) may be closed in order to seal the contents of the bag (3). Closing the sheath (2) may simply be done by tying a knot (6).

Claims

1. A disposable ostomy bag assembly comprising: a bag for receiving bodily waste materials, the bag comprising a flange secured to the bag and having an orifice to enable bodily waste to be received by the bag; and a compactable sheath comprising a first end and a second end, the first end being glued or welded to the flange, wherein the compactable sheath is constructed to close and seal the bag after use; wherein the flange is constructed to couple with and secure the assembly to a face plate on a patient's body, wherein the compactable sheath is extendable such that the second end extends away from the first end while the flange stays attached to the bag, and the compactable sheath at least partially circumscribes the flange in an extended position.

2. The disposable ostomy bag assembly of claim 1, wherein said bag and sheath are welded to said flange.

3. The disposable ostomy bag assembly of claim 1, wherein said sheath is glued to said flange.

4. The disposable ostomy bag assembly of claim 1, wherein said sheath is made from a plastic film.

5. The disposable ostomy bag assembly of claim 4, wherein the plastic film is selected from the group consisting of: polyethylene, polyethylene terephthalate, polypropylene, and polyvinylinene chloride.

6. The disposable ostomy bag assembly of claim 1, wherein said sheath is provided with folding lines for compacting the sheath lengthwise.

7. The disposable ostomy bag assembly of claim 1, wherein the flange comprises a front side and a bag-side facing the bag, and wherein said sheath is secured on the bag-side of the flange.

8. The disposable ostomy bag assembly of claim 1, wherein said sheath is provided with means for attachment to the body of a patient.

9. The disposable ostomy bag assembly of claim 8, wherein the means for attachment to the body of a patient is an adhesive layer on the surface of the sheath oriented towards the patient.

10. The disposable ostomy bag assembly of claim 1, wherein the compactable sheath has a tubular body extending from the first end to the second end.

11. The disposable ostomy bag assembly of claim 1, wherein the first end of the compactable sheath circumscribes the orifice.

12. A system for receiving bodily waste from an ostomy, the system comprising: the disposable ostomy bag assembly of claim 1; and a face plate on a patient's body, the face plate being capable of detachably coupling with the flange of the disposable ostomy bag assembly.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a side view of the ostomy bag assembly of the present invention, wherein the sheath is its compacted position.

(2) FIG. 2 shows a view of the ostomy bag assembly of the present invention, wherein the sheath is stretched and tied in a knot in order to seal the contents of the bag.

(3) FIG. 3 shows a view of the ostomy bag assembly of the present invention, wherein the sheath is stretched and adheres to the face place on the body of the patient.

DETAILED DESCRIPTION OF THE INVENTION

(4) The present invention solves the problems discussed above in prior art ostomy bags by providing an integrating closing mechanism for sealing the contents of the bag with a compactable sheath.

(5) The inventive ostomy bag assembly contributes to improved patient comfort and easy handling of used disposable ostomy bags.

(6) Reference is made to FIG. 1, which shows a side view of the ostomy bag assembly (1) of the present invention, wherein the sheath (2) is in its compacted position. In addition to the compactable sheath (2) the ostomy bag assembly (1) includes a bag (3) for receiving bodily waste materials; and a flange (4) for securing the assembly to the face plate (5) on the body of a patient. This ostomy assembly solves the problem of escaping malodour and bodily waste when the patient detaches the ostomy bag (3) from the face plate (5). The compactable sheath (2) can be stretched to acquire a cylindrical sheath extending from the flange, whereby the sheath may be closed in order to seal the contents of the bag (see FIG. 2).

(7) Reference is made to FIG. 2 showing a side view of the ostomy bag assembly (1) of the present invention, wherein the sheath (2) is stretched and tied in a knot (6) in order to seal the contents of the bag. This solves the problem of escaping malodour and bodily waste when the patient detaches the ostomy bag (3) from the face plate (5). FIG. 2 also shows the flange (4) for securing the assembly to the face plate (5) on the body of a patient.

(8) Reference is made to FIG. 3 also showing a side view of the ostomy bag assembly (1), wherein the sheath (2) is stretched and adheres to the face place (5) on the body of the patient. In order to ensure adherence of the sheath (2) to the face plate (5) the sheath (2) is provided (in this embodiment) with an adhesive layer. The figure also shows the flange (4) for securing the assembly to the face plate (5) on the body of a patient. Alternatively, the sheath (2) is provided with a rim or similar structure that can be affixed to the face plate (5). In this way the patient may detach the bag (3) from the face plate (5) without any malodour leaves the bag (3) until the patient detaches the sheath (2) from the face plate (5) before closing the sheath (2) and thereby sealing the contents of the bag (3). This manoeuvre may be done quickly so that only a minute amount of malodour leaves the bag.
