Abstract:
A hydrophilic, pressure-sensitive adhesive composition prepared by irradiating solid poly(N-vinyl lactam) with ionizing radiation to crosslink the poly(N-vinyl lactam) and thereafter mixing the radiation-crosslinked poly(N-vinyl lactam) with essentially unirradiated plasticizer in an amount sufficient to form a cohesive, pressure-sensitive adhesive composition. The composition is useful as a biomedical adhesive for transmitting or receiving electrical signals as a component of a biomedical electrode. The composition is also useful as a drug delivery device to deliver pharmaceuticals or other active ingredients to or through mammalian skin. The composition is also useful as a component in a skin covering for protecting mammalian skin Or mammalian skin openings with antimicrobial agents. A method of preparation of the composition is also disclosed.

Abstract:
An adhesive hydrogel dressing as well as methods of applying the dressing to a patient. The dressing generally comprises an adhesive hydrogel pad, a backing layer, and an adhesive layer on the backing layer facing the hydrogel pad. The adhesive layer and backing layer form a perimeter around the hydrogel pad and hold the hydrogel pad in place on an application surface. A release element is in contact with at least a portion of the edge of the hydrogel pad proximate the area that the hydrogel pad and release liner separate during liner removal.
Abstract:
A hydroalcoholic lotion is disclosed which comprises (a) a lower alcohol and water in a weight ratio of about 35:65 to 100:0, and (b) between at least 0.5% and 8% by weight thickener system comprised of at least one emulsifier present in at least 0.05% by weight wherein the composition in a polymer free state has a viscosity of at least 4,000 centipoise at 23 degrees C. and wherein the emulsifier is comprised of at least one hydrophobic group and at least one hydrophilic group. The hydroalcoholic composition is useful as a hand preparation such as a lotion or as a presurgical scrub replacement.
Abstract:
Skin antiseptic composition dispensers and methods of use are disclosed. The skin antiseptic composition dispenser may include a container with one or more walls that are substantially impermeable to ethylene oxide gas during normal ethylene oxide sterilization processes. In some embodiments, the container may include flexible walls free of metallic foil barrier layers. The containers may also include one or more vents in addition to one or more openings used to dispense the skin antiseptic composition within the container. The dispenser may include an applicator with a hydrophilic foam.
Abstract:
A sterilization indicator for testing the effectiveness of a sterilization procedure comprises a source of an enzyme, a sterilant-resistant chemical associated with the enzyme, and a substrate that reacts with the enzyme to form a detectable enzyme-modified product that provides an indication of the failure of the sterilization procedure. The sterilant-resistant chemical may be a polyglycerol alkyl ester, polyglycerol alkyl ether, an ethoxylated polyhydric alcohol ester, or a polyhydric alcohol ether. The indicator may be used to test the effectiveness of a hydrogen peroxide plasma sterilization procedure and may be provided with a non-challenge test pack or a lumen-challenge test pack.

Abstract:
Disclosed is a composition including a lower alcohol and water in a weight ratio of about 35:65 to 100:0, between at least 0.5% and 8.0% by weight thickener system comprised of at least two emulsifiers, each emulsifier present in at least 0.05% by weight wherein the composition free of auxiliary thickeners has a viscosity of at least 4,000 centipoise at 23 degrees C. and wherein each emulsifier is comprised of at least one hydrophobic group and at least one hydrophilic group. The composition is useful as a presurgical scrub replacement, a lotion or other hand preparation.
Abstract:
An incise drape suitable for use in surgical procedures. The drape comprises a substantially transparent flexible film that has at least a portion of one major surface coated or covered with a pressure sensitive adhesive, and a two liners removably covering the adhesive. Each liner has a handle spaced from the opposite side edges of the film, and a body portion attached to the handle. The body portion of each liner extends along the adhesive from handle in the direction away from the other liner. The drape is repeatedly folded over from the opposite side edges of the film toward the handles so that the drape may be unfolded and the adhesive exposed by pulling the handles apart.
