Description

PATENTS ACT 1977 A 1 0822GB-DMW Title: Ostomy bag
Description of Invention
This invention relates to an Ostomy bag, in particular to an ileostomy bag having a resealable drainage aperture and which is provided with means to seal the aperture and means to assist in opening the aperture to permit the contents of the bag to drain out.
Ostomy bags, such as ileostomy bags, that may be worn by patients for extended periods require periodic draining. Therefore, it is necessary to provide an ostomy bag which enables the user to empty the contents of the bag easily and quickly through a suitable drainage aperture and, once the contents of the bag have been discharged, clean around the drainage aperture and re-seal the drainage aperture so that the bag may continue to be used.
Ostomy bags incorporating resealable drainage apertures are known in the prior art, whereby the drainage aperture is formed between the outer walls of the bag which are otherwise sealed. Typically, the outer walls of the bag are tapered thus forming an elongate portion of the bag adjacent the drainage aperture. In order to effect a temporary seal of the drainage aperture, the ostomy bags may be provided with a separate sealing device, usually some kind of clip or tie which clamps across the elongate bag portion, or an integral sealing device secured to the bag adjacent the drainage aperture. Such sealing devices rely on the user carefully to roll up the elongate portion and then secure the sealing device in place.
To empty the bag effectively, the user must release the sealing device and then roll down the elongate portion. However, the contents of the bag generally cause the two walls of the bag to tend to stick together, thus making effective emptying and cleaning around the drainage aperture quite difficult.
It is an object of the present invention to provide an alternative form of ostomy bag which mitigates the problems of emptying the bag and cleaning S around the drainage aperture described above.
According to a first aspect of the present invention, there is provided an ostomy bag having first and second outer walls sealed together by a seam adjacent their edges to form the bag, and having an elongate portion leading to a drainage aperture wherein the bag includes a first flat strip of resilient I material on an outer surface of the first outer wall of the bag adjacent the drainage aperture and extending between the seam on either side of the elongate portion, and a second flat strip of resilient material on an outer surface of the second outer wall of the bag adjacent the drainage aperture and extending between positions at least lmm inside the seam on either side of the elongate 1 5 portion.
The second flat strip of resilient material may extend between positions at least 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm or Smm inside the seam on either side of the elongate portion.
The first flat strip of resilient material may be sealed to the seam on either side of the elongate portion.
Preferably the first flat strip of resilient material and the second flat strip of resilient material are located directly opposite each other.
An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings in which: FIGURE 1 is a view of the rear of an ostomy bag according to the invention when the drainage aperture is not sealed; FIGURE 2 is a view of the front of the ostomy bag of Figure 1 also when the drainage aperture is not sealed; FIGURE 3 is a side view of the ostomy bag of Figure 1 also when the drainage aperture is not sealed; FIGURES 4 and 5 are views from below the bag showing the process of opening the aperture step by step. s
Referring to the Figures an ostomy bag 10 has a rear outer wall 11 with outer and inner surfaces 11_ and l lb respectively, and a front outer wall 12 with outer and inner surfaces 12_ and 12b respectively. The rear and front outer walls 11, 12 are sealed by a seam 9, with inner edge 9_ and outer edge 9b, I lO around the majority of their outer edges to form the bag lO, but have elongate portions l lc and 12c respectively which extend downwardly at the bottom of the bag lO to form an elongate portion lOc of the bag 10. The sides of the elongate portions 1 lc and 12c are sealed by the seam 9 but bottom edges 11_ and 12_ are not and thus form a drainage aperture 13.
15Typically the outer walls 11, 12 of the bag 10 are formed from ethyl vinyl acetate copolymer and the seam 9 is formed by heat welding. The seam 9 is typically several millimetres wide between its inner 9_ and outer edges 9b, such as 4-6 mm.
The bag 10 is provided in known manner with a securing ring 14 for attaching the bag to the wearer, and an inlet aperture 15 surrounded by the securing ring 14. The bag 10 may have additional intermediate walls, filters etc. as are known in the prior art, but as they are not relevant to the present invention will not be described here.
The bag lO further includes a first flat strip of resilient material 16 which is secured to the outer surface 12a of the front outer wall 12 adjacent the drainage aperture 13, and a second flat strip of resilient material 18 which is secured to the outer surface l l_ of the rear outer wall 11 also adjacent the drainage aperture 13. The first flat strip of resilient material 16 extends at least between the inner edges 9_ of the seam 9 on either side of the elongate portion lOc of the bag 10, and may be incorporated into the seam 9 at either end. The second flat strip of resilient material 18 extends between positions approximately 3.5mm inside the inner edges 9_ of the seam 9 on either side of the elongate portion lOc, leaving portions 1 le of the rear wall 11 between the ends of the second flat strip of resilient material 18 and the inner edges 9a of the seam 9.
The bag 10 further includes means to seal the bag 10. This will only be described in very briefly as it is of known the form. The means to seal the bag comprises tabs 20 formed integrally with the rear wall 11 and extending I outwardly to either side of the bag 10 adjacent where the elongate portion 10 extends from the main portion of the bag 10. The tabs 20 have, on their frontward facing surfaces hooks of known hook & loop fastener. The means to seal the bag 10 further comprises a portion of the loops 21 of known hook & loop fastener secured to the outer surface 11_ of the rear wall 11 just below the tabs 20.
When the bag 10 is to be sealed the elongate portion 10_ is rolled up around the first and second flat strips of resilient material 16, 18 and the tabs 20 are folded inwardly such that the hooks of the hook & loop fastener contact and engage with the loops 21 of the hook & loop fastener to retain it in that condition. When the bag 10 is to be unsealed the above a process is reversed.
Then the elongate portion lOc is gripped adjacent the drainage aperture 13 between the thumb T1 and forefinger F1 of the wearer, as shown in Figure 4, and the thumb T1 and forefinger F1 are squeezed together as represented by; arrows Al in Figure 5. Doing so causes the first flat strip of resilient material 16 to bend, and the portions I le of rear wall 1 1 between the ends of the second flat strip of resilient material 18 and the seam 9 collapse until the ends of the second flat strip of resilient material 18 contacts the thumb T1 and forefinger F 1 of the wearer. At that point the second flat strip of resilient material 18 also bends, and reliably does so in the opposite direction to the bend of the first flat strip of resilient material 16. Thus the drainage aperture 13 is opened allowing the contents of the bag 10 to be drained out, and the area around the drainage aperture 13 to be cleaned by the wearer, before the bag 10 is resealed.
Thus the drainage aperture 13 is opened by the user without any risk of soiling of the fingers. The drainage aperture 13 can be maintained open simply by keeping the thumb Tl and forefinger F1 of the first hand in the position shown in Figure 5. Thus the user's other hand can be used to clean around the aperture 13 before resealing the bag 10.
Opening the drainage aperture 13 in this way assists in both emptying I the bag 10 of the waste contents therein, and in cleaning of the bag 10 around the drainage aperture 13 prior to resealing in the manner described above.
The flat strips of resilient material 16, 18 are conveniently made from a plastics material such as acetyl copolymer, and heat welded to the bag 10, but may also be formed from any appropriate material and secured to the bag by any appropriate means.
Although the embodiment described above is described with the first flat strip of resilient material 16 on the outer surface 1 la of the rear outer wall 11 and second flat strip of resilient material 18 on the outer surface 12_ of the second outer wall 12, embodiments may be constructed with these features transposed. That is the first flat strip of resilient material 16 may be secured to the outer surface 12_ of the second outer wall 12, and the second flat strip of resilient material 18 may be secured to the outer surface 11_ of the first outer wall 11. In addition the bag 10 may be provided with any appropriate means for sealing it, and this need not be as described above.
The embodiment described above has the second flat strip of resilient material 18 leaving portions l l_ of the rear wall l l, between the ends of the second flat strip of resilient material 18 and the seam 9, which are around 3.5mm in width. However these portions of the rear wall 1 lmay be of any other width which provides the same benefit in terms of the drainage aperture opening correctly when the sides of the elongate portion 10_ are squeezed together, for examples lmm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm and 8mm or indeed any width therebetween.
The first flat strip of resilient material 16 may extend beyond the outer edge 9b of the seam 9 on one or both sides of the elongate portion 10c.
In the present specification "comprise" means "includes or consists of" and "comprising" means "including or consisting of".
The features disclosed in the foregoing description, or the following lO claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
