Abstract
A bag side ostomy coupling element has a flange surrounding a stomal orifice and has a coupling portion by means of which it can be coupled to a body side coupling element. The flange has an extension at an upper part thereof, i.e. towards the top of the bag when the element is connected thereto, the extension being such as to be capable of serving in use to accommodate a filter, the filter accommodated preferably being of the 'snap-in' type. <IMAGE>
Description
1 GB 2 177 926 A 1
SPECIFICATION Ostomy Appliances
1 1 This invention relates to ostomy appliances and in particular to a bag side coupling element for use on or with an ostomy bag, and to bags including such 70 elements.
According to the invention, there is provided a bag side coupling element for an ostomy bag, the element having a flange surrounding a stomal orifice and a having a coupling portion by means of which it can be coupled to a body side coupling element, characterised by the flange having an extension at an upper part thereof, (i.e. towards the top of the bag when the element is connected thereto) the extension including a flat portion 80 having a gas passage hole therein and a peripheral wall attached to the flat portion, the peripheral wall serving to define a filter-receiving recess.
The wall may have a detent portion for retaining a snap-in cover for the fitter receiving recess. The filter 85 is preferably a filter in accordance with our U.K.
Patent Application No. 85 17872.
According to a preferred embodiment of the invention, the flange and its extension are integrally moulded from synthetic plastics material. A disc 90 filter may be disposed within the filter-receiving recess.
In an illustrated embodiment of the invention, the coupling portion is formed as a so-called "snaplock coupling" in which an interengaging rib and channel effect a connection between a bag-side and a body side ostomy coupling element. For a fuller description of various versions of this type of coupling, which has enjoyed great commercial success, the reader is referred to U.K. Patents Nos. 100 1,571,657, 1,583,027, 1,586,823, 1,586,824, a n d 2,121,902.
The invention will be better understood from the following non-limiting description of an example thereof given with reference to the accompanying drawings in which:
Figures 1 and 2 are respectively elevation and sectional views of an alternative embodiment of bag side coupling element for use with an ostomy bag; Figures 3 and 4 are cross-sectional views on an enlarged scale of parts of the element shown in Figure 2; and Figures 5, 6 and 7 are respectively top plan view, central cross-sectional view and side view of one example of snap-on filter cover according to the invention and which is usable with the coupling element shown in Figures 1 and 2.
In the drawings, like parts are represented by like reference numerals.
Figures 1 and 2 illustrate a bag-side coupling 120 element 80 having an extension 82 and tabs 84 for the attachment of a belt, not shown. The bag-side coupling element has a peripheral channel section for receiving a counterpart body-side coupling element in the manner described and claimed in U.K. Patent 1,571,657. The extension 82 has a base wall 86 which has a central hole 88 therein. In use, the hole 88 is aligned with a pre-punched hole in the adjacent wall of an ostomy bag which is suitably secured to the coupling element over the surfaces indicated at 90.
This arrangement offers considerable advantages in manlufacture of ostomy bags and to the best of Applicants' knowledge is entirely new. It permits more rapid and economical manufacture. In one plastics welding or bonding operation, a first bond between the flange and one bag wall surrounding the stomal aperture and second bond between the extension and the bagwall surrounding the gas exit aperture are produced. In addition, in the same operation, the gas exit hole and the stomal orifice are punched out of the bag wall. Thereafter, a peripheral bond is made in conventional manner to secure the two bag walls together. The fixing of the filter in the arrangement according to the present invention is more reliable and satisfactory than that in the arrangement according to U.K. Patent No. 2 121902, in that the construction allowing a lid or cover to be fitted as a press fit with resilient engagement ensures the filter is properly retained and minimises the possibility that gas to be deodorised can by-pass the filter. It will be realised that to avoid gas by-pass in the arrangement of the '902 Patent requires a close fit between the filter and its housing and this is likely to give rise to problems in high speed quantity manufacture.
The extension 82 has an internal groove 62, an upraised rib 66, and a bevel 70. The purpose of these parts is the same as that described in connection with Figures 6 and 7 of U.K. Patent Application No. 85 17870 to which the reader is referred.
The filter cover illustrated in Figures 4, 5 and 6 has a top wall 100 connected to a substantially cylindrical wall 102. The filter cover is preferably made of a synthetic plastics material such as high density polyethylene but any material suitable for the "snap fiV connection may be used. The wall 102 has an external rib or detent 104 for engagement in the groove 62 described above. The top wall 100 has square holes 106 therein and is of substantially oval shape as seen in plan, having flanges 110, 112 which extend beyond the confines of the wall 102. These flanges are provided to enable a user to separate the filter cover from the extension, e.g. by inserting a finger nail underneath the flange 110 and lifting. A shallow cylindrical space 114 accommodates a circular disc filter. Any known form of circular disc filter may be employed, but the preferred filter medium is that disclosed and claimed in our U.K.
Patent Application No. 85 03 749.
It has been found advantageous to provide exit holes 106 for the gas which are of tapered configuration, the walls of the holes tapering inwardly so that the hole cross-sectional area at the inner surface 120 (Fig. 13) of the wall 100 is less than the hole cross-sectional area at the outer surface 122 of the wall. Alternatively a simple non-perforated cap for the filter housing can be employed, if desired when no filter pad is needed.
It will be seen that in use the filter cover can readily be attached to the extension 82 by pushing it on so that the snap fitting parts 104 and 62 interengage. Of course it will be normal to place a filter disc within the space 114 before snapping the 2 two parts together. If desired, the filter disc may be 45 fixed to the cover, e.g. by a small dab of adhesive.
When they are snapped together, the raised rib 66 pinches the filter at a circular location space just inwardly of its outer periphery so ensuring that any gas leaving the ostomy bag through the hole 56 or 50 88 and entering the filter housing defined by the interengaging walls 60 and 102 (or 82 and 102) is constrained to pass through the filter to reach the exit holes 106 and cannot by-pass the filter. A new filter can easily be inserted without removing the ostomy bag. Hence there is no need to uncouple the body side and bag side couplings when changing a filter, nor any need to remove the body side attachment member from the peristornal skin region. Hence undesired disturbance of this skin region is midimised.
As will have been understood from the foregoing description, it is not essential that the coupling between the bag and the body-side pad should be byway of a flat flange and adhesive. As an alternative, any known ostomy coupling arrangement may be employed and in particular the coupling arrangement described in the patents cited above may be used. An advantage of the invention as particularly disclosed herein is that manufacture of ostomy bags is greatly simplified, it being possible to use the same bag-side coupling element for bags having filters as for bags which do not have filters, and separate manufacturing steps directed to attachment of filter housings or filters being avoided or at least reduced or simplified.
