A no-sting skin protectant film forming composition is formulated with a film forming polymer having both polar and nonpolar characteristics, a no-sting nonpolar solvent system, and at least one skin health ingredient. The no-sting skin protectant film forming composition is configured to form a protective film on a skin surface after the solvent system evaporates.

An ostomy appliance has a waste collection container and an anti-reflux component disposed inside of the waste collection container. The anti-reflux component is connected to the top end portion of the waste collection container only above a center of an inlet opening for a stoma.

This invention relates to regenerable antimicrobial coatings with long-lasting efficacy for use in medical applications including implants, medical instruments or devices, and hospital equipment. The same coatings would also have broad utility in the consumer, industrial, and institutional markets. The coating technology would be based on sequestration of hydrogen peroxide (HP) by zinc oxide binders incorporated into the coatings.

An ostomy bag insert (104) comprising a polyacrylate superabsorbent (300) and a powdered zeolite (301). The ostomy bag insert is configured to absorb fluids excreted by the body and to control odours resultant from the excreted matter within the ostomy bag (100). The present zeolite exhibits enhanced odour control.

The disclosed hydrophobic adhesive composition comprises a hydrophobic adhesive matrix and water absorbent fibers dispersed throughout the adhesive matrix to provide water management capabilities to the adhesive composition. The disclosed adhesive composition can adhered to a variety of surfaces, such as skin, and will easily remove from the surface. Therefore, the disclosed adhesive is particularly well suitable for application to skin wherein the absorbent fiber can absorb perspiration, water, or wound fluid from skin.

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.

Disclosed herein are chitosan hydrogels including one or more metal ions. The hydrogels have antimicrobial properties and can be used to treat wounds and other openings in the skin.

An adhesive wafer for attaching a waste collecting pouch to a body includes a backing layer, a skin-facing adhesive layer, and an absorbing adhesive layer. The skin-facing adhesive is liquid impermeable and has a water absorption capacity less than 8 weight % and a moisture vapor transmission rate (MTVR) at least as high as 150 g/m.sup.2/24 h. The absorbing adhesive layer is disposed between the backing layer and the skin-facing adhesive layer. The absorbing adhesive layer has a water absorption capacity at least as high as 15 weight %.

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).
