Embodiment Construction

[0025] During the use of ostomy bags with filters protected by various foam elements or porous membranes, the filter may be inserted into the foam and / or arranged with the gas inlet openings to protect the deodorizing filter Clogging of solid or semi-liquid waste in contact with the membrane. The known filters described above are designed with minimal access to the protective elements in the path and thus reduce the risk of these elements becoming clogged. On the other hand, narrow channels complicate the removal of waste material once waste enters the protection element and clogs the filter.

[0026] The present invention relates to a filter for an ostomy appliance which can be cleaned in situ during use.

[0027] According to the invention, the filter which is emptied and cleaned in situ can be provided by forming a path for gaseous waste which is open at one end and connected at the other end to the gas inlet opening of the deodorizing filter body and / or by making on the ...

Abstract

The present invention relates to an in situ cleanable filter for an ostomy appliance comprising a pathway for leading gases to a vent in an ostomy bag and a protective element contained in said pathway to prevent solid or semi-liquid waste from blocking the pathway where a channel or compartment formed by liquid impermeable layer(s) (3, 4) is defining at least part of the pathway and at least a part of said compartment or channel contain a protective element (1, 2) of an open celled compressible material having a memory and having a pore size of at least 60 PPI, said protective element extending in the same direction as the gas flow within the channel or compartment, said channel or compartment having an opening providing access to the pathway from the interior of the bag, said pathway having another opening (8) being connected to a vent (9) in the ostomy bag, optionally via a deodorizing filter (7). The invention relates to an ostomy appliance comprising a filter as above and a method for emptying and cleaning the filter.

Description

technical field [0001] The present invention relates to an ostomy appliance having a filter which is washable in use, to an ostomy appliance comprising such a filter, and to a method of cleaning the filter. Background technique [0002] The present invention relates to use in receiving body waste from colostomy or ileostomy patients, and in particular to filters for use in conjunction with ostomy bags to remove flatus collected in the bag before releasing it into the environment The stench of the gas. [0003] Such filters and the problem of solid or semi-liquid waste clogging the filter and causing filter failure are described in various patent documents. A method of protecting a filter from clogging with liquid and solid body waste is also described. This method involves covering the inlet of the filter with a porous protective membrane and foam. [0004] Thus, EP607028 discloses an ostomy bag for retaining body waste comprising a bag made of flexible plastic sheet mate...
