Description
2201141 (~
A filter arrangement for a collection bag for body exudates.
The invention relates to a filter arrangement for a collection bag for body exudates, in particular an 5 ostomy bag with a vent, comprising a filter holder fastened to a wall of the bag at the vent and having a through hole forming a passage from the interior of the bag to the surroundings, and a replaceable filter insert designed for positioning in said hole.
It is known to design bags for collection or drainage with a vent for decharging gases which are accumulated in the bag during use and which without this precaution would entail a distension of the bag making the bag noticeable under the user's clothing. Especially 15 in cases with ostomates who have been provided with an artificial opening formed surgically in the abdominal wall for connection of the intestinal system with the ostomy bag, the vent is usually equipped with some kind of deodorizing filter in order to avoid odour nuisances 20 when the escaping flatus reaches the surroundings.
Furthermore, it is known to change the filter when it has lost its deodorizing effect or has been clogged such that the bag need not be disposed of due to the shorter life of the filter.
In prior art filter arrangements of the above-mentioned type as known eg. from DK publication no. 162 136, US-A-4,411,659 and US-A-4,451,258 a replaceable filter element is arranged in a filter holder. In these designs, the vent is open during the replacement thus 30 permitting the flatus to escape, perhaps together with matrial collected in the bag if the user is eg. in a lying position. Besides, it will during replacement be necessary to touch the used filter element which must furtermore be disposed of, and the replacement must AMENDED SHEET
2201 141 : i therefore be carried out in a place where the user may both discard the filter element and subsequently wash his or her hands.
With this end in view, it is an object of the 5 invention to provide a filter arrangement which makes it easier and more comfortable for the user to replace the filter insert, the user avoiding to touch the filter, and where during the replacement, the vent remains closed all the time and at the same time, a good 10 retention of the filter insert is secured when the filter arrangement is in use.
This purpose is fulfilled by a filter arrangement which is characterized in that for position fixing of the filter insert in a use position, the filter holder 15 has means for engagement with corresponding means on the filter insert which engagement means are designed such that upon positionng in the use position, the filter insert is prevented from being withdrawn from the filter holder, and that at the end of the filter holder facing 20 the interior of the bag an elastically resilient clamping member is provided which in the use position forms a sealing around the filter insert but allows that this is pushed from the outside through the hole of the filter holder into the bag.
Thereby is provided a tight and secure fastening of the filter insert in the filter holder and, at the same time, no gases escape during replacement and-furthermore, it is possible to place a new insert in the holder without touching the used perhaps soiled filter 30 insert. Besides, there is obtained the advantage that the used filter insert is disposed of in connection with emptying the bag.
In a structurally simple embodiment, said engage-ment means are formed by an inwardly facing shoulder 35 portion in the filter holder and a corresponding ~EN~E~SHEET
2201 141 .
2a outwardly facing shoulder portion on the filter insert, where the filter insert within said shoulder portion has AMENDED SHEET
WO96/10378 PCT~K95/00387 an internal conical end part with inwardly convergent cross section, and where the elastically resilient clamping member of the holder forms a sealing lip around said end part of the insert. By the complementary shape 5 of the engagement means in the filter holder and on the filter insert, respectively, a seal and formlocking connection between these components is obtained in the use position, at the same time as it is possible with one grip to replace the filter insert.
In a preferred embodiment of the invention, the filter holder is designed with two parts with a first annular socket part fastened to the bag wall whereas the through hole for the filter insert is formed in a second part designed as an openable plug part for placement in 15 said socket part. By this embodiment, a ventilating possibility is provided when the filter is clogged and it is not possible and suitable to replace the filter insert. The plug part is in that case lifted from the socket part and the air staled in the bag is released 20 whereafter the plug part is placed again on the socket part.
The plug part and the socket part of the filter holder may preferably be connected through an integrated hinge (film hinge) or an integrated strap by which it 25 is avoided that the plug part is mislaid or lost.
The socket forms appropriately an outwardly facing collar with relatively low height around the bag opening, whereas the plug part is formed essentially as a ring with a mainly U-shaped cross section for clamping 30 engagement with the outwardly facing collar of the socket. This limits the height of the filter arrange-ment, the bag with the filter arrangement thus providing the discretion aimed at.
WO96/10378 PCT~K95100387 As a further advantage, a hose coupling for a hand shower hose may be placed on the socket of the holder thus providing a possibility for rinsing the bag.
The first annular socket part or filter holder may 5 eg. be produced by moulding in a manner known per se.
The filter insert may eg. be produced by moulding of a tube, after which the very filter is inserted, or perhaps by moulding direct around the filter. Alternati-vely, the filter insert may be extruded around the very lO filter whereupon the filter insert is embossed by an embossing tool in order to, on the exterior, form members for retaining the filter insert in the holder part.
A watertight, but gas-permeable membrane may be 15 glued against the part of the filter insert facing the interior of the bag. A top covering for closure of the outward facing end of the filter holder may likewise be fastened by gluing in a manner known per se. The filter arrangement may be fastened by gluing or welding to the 20 front wall of the bag.
The invention will in the following be explained more in detail with reference to the schematical drawing, where Fig. l shows a filter arrangement according to the 25 invention placed on an ostomy bag, Fig. 2 on a larger scale a sectional view of the filter arrangement according to the invention, Fig. 3 a view as in Fig. 2, but with another embodiment of the filter arrangement, and 30Fig. 4 a view as in Fig. 2, but with yet another embodiment of the filter arrangement.
In Fig. l is shown a bag l which is meant for collection of body exudates and which in the shown embodiment is an ostomy bag consisting of two walls 2, 35 3. In the rear wall 2 of the bag which in the use WO96/10378 PCT~K95/00387 position is the wall facing the user, there is an opening 4 which via non-illustrated fastening members known per se is meant for connection with the patient's stoma. In the bottom part of the bag is a drainage 5 device, not shown, which is closed when the bag is in use, for emptying the bag for its content. A vent in the form of a hole 5 is designed in one of the walls 2, 3 of the bag or in a seam where the two walls are welded together. The vent 5 is meant for receiving a 10 filter arrangement 6.
The structure of the filter arrangement 6 appears from Fig. 2 where a filter holder 7 which may be moulded of plastic material is fastened by eg. gluing or welding on the place where the vent 5 is designed 15 and which in the shown embodiment is the front wall 3 of the bag. In the filter holder 7 is placed a filter insert 8 with essentially cylindrical cross-sectional form and consisting of a moulded tube 9 with a watertight, but gas-permeable membrane 10 in the end 20 facing the interior of the bag. A filter material 11 of a type known per se, such as active coal, is placed in the tube 9 which is closed at the end by a gas-permeable top covering 12 with at least the same gas-permeability as the membrane 10.
The filter holder 7 has engagement means for fastening of the filter insert 8 in the form of an inwardly facing shoulder portion 13 preventing the filter insert 8 in moving outwards in the way that a corresponding outwardly facing shoulder portion 14 on 30 the filter insert 8 abuts on the shoulder portion 13 of the filter holder 7. In the end of the filter holder 7 facing the interior of the bag is a resilient clamping part which is here designed as a sealing lip in sealing abutment against a conical end portion 35 of the filter insert 8. The diameter of the filter holder 7 is ajdusted such that the tube 9 at an outer end edge has a diameter which essentially corre-sponds to the diameter of the inner ~-nd edge. During replacement of the filter insert, the used insert 8 5 placed in the filter holder 7 is pressed inwards in the way that a new filter insert is lead from the outside into the holder where the inner end edge of the new insert is pressed against the outer end edge of the filter insert 8 in the filter holder 7. The conical 10 end portion eases this insertion and presses the sealing lip 15 radially outwards such that the used filter insert 8 falls down in the bag.
In Fig. 3 is shown another embodiment of the filter arrangement 6 a first annular socket part 16 and a 15 second openable plug part 17. The socket part 16 is by a flange portion 18 fastened to the bag wall 3 and has an outwardly facing collar 19 meant for engagement with the plug part 17. The plug part 17 has the form of a ring with U-formed corss-section for 20 clamping engagement with the collar 19 on the socket part 16. The hole of the filter holder for receiving the filter insert 8 is designed in the plug part 17 and is in the same way as in the embodiment shown in Fig. 2 designed with engagement members 13, 14 for 25 retention of the filter insert 8 which is designed in a corresponding way as in the above described embodi-ment. The plug part 17 is in this embodiment connected with the socket part 16 by means of a hinge 20 which may be a film hinge of a type known per se or an elastic 30 strap whose ends are fastened to the socket part 16 and the plug part 17, respectively. In order to rinse the bag, a hose coupling for a hand shower hose may coupled be on the collar l9 on the socket part 16 after the plug part 17 has been opened.

WO96/10378 PCT~K95100387 Finally, in Fig. 4 is shown an embodiment where the filter holder 7 is designed with a flange portion 21 which is fastened by glue to the bag wall 3 in such a way that the longitudinal axis of the through hole of S the filter holder forms an angle ~ which may eg. be placed in an interval between 5 and 45 with the general plane of the flange portion 21. A plane through the end section of the flange portion 21, however, forms another angle with said longitudinal axis. By this 10 design, the filter holder 7 projects with the filter insert 8 obliquely into the bag 1 and has thus a small extent in a direction at right angles to the plane of the bag.
