This disclosure relates to deodorizing compositions, ostomy devices, and uses thereof. In certain embodiments, the disclosure contemplates a deodorizer comprising a combination of citric acid and a citric acid salt, cocamidopropyl betaine, zinc ricinoleate, and optionally comprising a preservative such as a paraben. In certain embodiments, the deodorizing composition is contained loaded in a hydrogel or hydrophilic polyurethane. In further embodiments, the loaded hydrogel or hydrophilic polyurethane is placed in an ostomy device.

An object of the present invention is to provide a feces treatment agent for colostomy, which on the assumption that characteristics required as a lubricant are shown, can maintain or improve the feces discharge properties from a colostomy pouch, inhibit the development of feces odor, and improve operativity and portability. A feces treatment agent for colostomy, in which an agent A including (1) a granular water-soluble lubricant, (2) a granular water-absorbing gelling agent, (3) sodium bicarbonate, and (4) a component including at least one selected from the group consisting of zinc oxide, limonite and zinc sulfide is contained in a water-soluble base material.

A method includes identifying a stoma at an initial position. The method also includes identifying one or more portions of a leak originating from the stoma at an initial position. The method further includes applying a composition to the one or more portions of the leak. The composition includes bentonite clay and guaran. The bentonite clay and guaran enable the composition to soak the one or more portions of the leak, and prevent the one or more portions from continuing to flow. The method also includes determining whether additional portions of the leak have originated from the stoma after the composition has been applied.

Described herein are medical devices and medical implements with high lubricity to flesh (or biological fluid) and/or inhibited nucleation on its surface. The device has a surface comprising an impregnating liquid and a plurality of micro-scale and/or nano-scale solid features spaced sufficiently close to stably contain the impregnating liquid therebetween. The impregnating liquid fills spaces between said solid features, the surface stably contains the impregnating liquid between the solid features, and the impregnating liquid is substantially held in place between the plurality of solid features regardless of orientation of the surface.

The invention provides an ostomy bag assembly comprising outer (2) and inner (4) bags secured to one side of an adhesive flange (6); the adhesive flange (6) having means defining an orifice to enable bodily waste from a stomal opening to be received by the inner bag; wherein the adhesive flange is of laminar construction and comprises, in sequence, from a body-contacting surface outwards: (a) a bioadhesive layer (10) for securing the flange to a body surface of a patient about the stomal opening; (b) a first polymeric support layer (8) attached to the bioadhesive layer (a); (c) a heat sealable layer (16) having a heat sealable adhesive surface which releasably bonds the heat sealable layer to the first polymeric support surface; (d) a second polymeric support layer (14) bonded to the heat sealable layer; (e) a weldable polymeric layer (18) to which the inner and outer bags are attached, the weldable polymeric layer being bonded to the second polymeric support layer;
the adhesive flange having an annular channel (20) which surrounds the means defining the orifice and extends through layers (c), (d) and (e) so as to form radially inner (22) and outer (24) attachment zones separated by the annular channel (20), the inner bag (4) being attached to the radially inner attachment zone (22) and outer bag (2) being attached to the radially outer attachment zone (24);
and wherein the inner and outer bags (4),(2), together with attached portions of layers (c), (d) and (e) can each be peeled away from the first polymeric support layer (b).

Also provided by the invention are adhesive flange blanks from which the ostomy bag assemblies can be manufactured, as well as methods for the manufacture of the ostomy bag assemblies and the adhesive flange blanks.

A body waste collecting device includes a collecting pouch and an adhesive wafer for attachment to the body. The adhesive wafer includes a backing layer, a first adhesive and a second adhesive. The second adhesive includes a polar plasticizing oil or a combination of polar plasticizing oils in the content of above 10% (w/w) of the second adhesive, and at least one polar polyethylene copolymer, where the content of the polyethylene copolymer is 10-50% (w/w) of the second adhesive, and the polyethylene copolymer has a melt flow index below 2 g/10 min (190 C./21.1N).
