Abstract: An ostomy coupling device comprises a faceplate for placing over the stoma including a neck having outwardly facing threads, and a generally cylindrically shaped screw coupling having threads on the inner surface thereof. The narrow portion of an ostomy pouch is placed over the neck, and the screw coupling is thereafter rotated onto the neck, whereby the aperture collar of the pouch is conformed to the space between the matching threads of the screw coupling and faceplate, thereby providing a seal between the pouch and the stomal aperture.

Abstract: The ostomy bag includes a multi-stage filter system that provides contamination protection for a deodorizing filter in the system. The multi-stage filter system also includes a gas transmissible protection filter that is impassible to semi-liquid waste material. The protection filter is located in the ostomy bag to precede the deodorizing filter such that gaseous waste must pass through the protection filter before it passes through the deodorizing filter. In one embodiment of the invention wherein the ostomy bag has a single chamber, the protection filter is a two layer structure with different pore counts that overlay the deodorizing filter. In another embodiment of the invention wherein the ostomy bag has dual chambers, the protection filter, without overlaying the deodorizing filter, is disposed across the flow path of gaseous waste to the deodorizing filter such that any gaseous waste that reaches the deodorizing filter must flow through the protection filter.

Abstract: A coupling for joining a pad or dressing to an ostomy bag including a first member 10 of closed loop form for defining a stoma aperture therein, the first member having a formation which defines two opposed walls, 11, 12, and a second member 20 of closed loop form also defining a stoma aperture. The second member has a projection or wall 21 dimensioned and positioned to fit between and resiliently bear against at least one of the walls when the members are connected in such a way as to make sealing engagement with at least the said one wall. The first member is of channel formation seen in cross section and has an upstanding tapering rib 24 extending from the base of the channel and between its walls. The second member has a tapering groove, of substantially complementary shape to the rib, in that surface of the rib projection or wall 21 which faces towards the first member in the mutually coupled condition of the first and second members.

A generally cylindrically shaped sheath portion has one end securely attached to the ring portion and a second end. The sheath includes a channel configured to accept the body passage through to the aperture on the ring portion. The sheath is made of a nonabsorbable, noncorrosive mesh material which allows the naturally occurring scaring process of the patient to fibrotically attach the sheath to the body passage, and thereby fixedly secure the ring portion to a substantially permanent location on the surface of the patient's body from within the patient's body.

The absorbent pad is further characterized in that it can be applied and disposed of separate and apart from the ostomy appliance.

Abstract: In the first embodiment, the faceplate coupling ring is of conventional design and includes an axially extending rib with a radially outwardly extending rim and a radially inwardly extending deflectable sealing strip. The pouch coupling ring includes inner and outer spaced walls, forming a channel for receiving the rib.

One of the coupling rings, preferably the faceplate coupling ring, is provided with a substantially non-compressible insert that includes an axially-extending collar, a bulbous non-deformable wedge body, and a radially-extending pivot stem that centrally connects the collar and wedge body. The pivot stem allows limited forward and rearward rocking movement of the wedge body about a pivot axis extending through the stem. A massive front portion of the wedge body has an inwardly and rearwardly curved bearing surface of progressively increasing distance from the pivot axis so that the radial width of the insert decreases as the wedge body rocks rearwardly and forceably increases as it rocks forwardly about the axis, in response to frictional engagement with the walls of the channel, when coupling and uncoupling forces are exerted on the rings.

The exposed adhesive surface of the wafer directly contacts the adhesive of the body side of the dressing to form a secure bond. The result is a dressing with a convex shaped body side having a substantially uninterrupted layer of adhesive.
