Abstract: A cyanoacrylate adhesive is applied to the skin areas prone to blistering prior to blister formation.

Abstract: An adhesive dressing sheet is disclosed, comprising a polymer film having a high flexibility, an adhesive layer provided on one side of the polymer film, a peeling liner temporarily provided on the adhesive layer, and a flexible sheet on the other side of the polymer film, wherein a bending line is provided on the peeling liner in a direction almost at right angles to the peeling direction of the liner, and the flexible sheet has self supporting properties such that when the liner is peeled off up to the bending line and bent, the liner bending piece does not expand to an angle of 90.degree. or more.

Abstract: A dressing for wounds or dermal ulcers. The dressing includes a semi-permeable, transparent polyurethane film and a plurality of concentric polyethylene foam rings or disks. Application of foam rings to a semi-permeable thin film permits modification of the moisture/vapor transmission characteristic of the wound dressing which can be adjusted to suit the wound environment.

Abstract: Improved transdermal drug delivery systems are provided which contain an occlusive, elastomeric backing layer which is preferably liquid-resistant. The systems contain as a backing layer a single homogeneous sheet of an elastomeric material having a moisture vapor transmission rate ("MVTR") in the range of about 0.1 to 20 g/m.sup.2 /hr and a Young's modulus in the range of about 10.sup.4 to 10.sup.9 dynes/cm.sup.2. Methods for making and using transdermal drug delivery devices containing such backing layers are provided as well.

Abstract: A tape for attaching bandages, with non-adhesive tabs at each end for easy manipulation and removal while wearing gloves, are disclosed. Also disclosed are a temporary bandage with non-adhesive ends; a roll formation of such tapes, each tape section separated from the others by a perforated section, such that it may be easily removed from the roll; and methods of forming the tapes and bandages.

Abstract: Membranes suitable for use as wound dressings and in particular as synthetic skin substitutes are disclosed. The membranes consist of a natural or synthetic polymer, a non-gellable polysaccharide and a cross-linking agent.The membranes of the invention may contain one or more additional components selected from water-loss control agents, emulsifying agents and plasticizers. An internal reinforcing material may also be provided to supplement the inherent mechanical strength of the membrane.Methods of forming such membranes are also disclosed.

Abstract: A medical dressing comprising an embossed, thin polymeric film coated on one side with a medical grade, pressure-sensitive adhesive. The embossed film has a low coefficient of friction, preferably less than about 0.6, on the outer adhesive free surface which makes the film particularly resistant to unintentional removal by rubbing forces. The film is intended primarily for use as a blister dressing, but may also be provided with an absorbent pad for use as a wound dressing.

Abstract: Inherently tacky, emulsion pressure-sensitive adhesive polymers comprising about 35 to about 65 percent by weight alkyl acrylates, about 15 to about 35 percent vinyl esters, about 20 to about 35 percent by weight diesters of a dicarboxylic acid, and up to about 5 percent by weight of an unsaturated carboxylic acid formed in the presence of a reactive surfactant and having a gel content of about 50 to 70 percent by weight as formed are used in sterilizable bandage and medical tape constructions.

Abstract: An adhesive tape preparation of clonidine is disclosed, comprising a polytetrafluoroethylene porous sheet having an air permeability of from 10 to 500 seconds having thereon an active ingredient-containing layer comprising a pressure-sensitive adhesive obtained by copolymerizing a monomer mixture comprising from 40 to 80% by weight of 2-ethylhexyl acrylate, from 20 to 60% by weight of 2-methoxyethyl acrylate, and 0 to 40% by weight of vinyl acetate, the pressure-sensitive adhesive containing clonidine as an active ingredient. The preparation achieves sustained release of clonidine and exhibits long-term preservability while minimizing skin irritation and maintaining sufficient adhesion to the skin.

Abstract: A compress for dressing wounds contains a depot layer (1) for storing liquids. A guiding layer (2) is assigned to the side of the depot layer (1) which faces the front side of the compress, which guiding layer is constructed in such a manner that the secretion which reaches it can spread out predominantly along said layer (2), before it reaches the depot layer (1). In order to achieve this effect, channels (3) are formed in the surface of the guiding layer (2) which faces the front side of the compress. Said channels (3) extend in the direction of the surface of the guiding layer (2). The two layers (1, 2) are arranged between a surface ply (10) and a lower sealing layer (15), the edges (16, 17) of which are bonded. Liquids which reach the surface layer spread out rapidly and evenly over the entire surface of the compress.

Abstract: Combinations of alkyl siloxy siloxane-containing polymers admixed with liquid polydimethylsiloxanes are excellent non-stinging, non-irritating liquid coating material for forming films which act as conformable bandages adhering to and protecting nails, skin and mucous membrane wounds from abrasion, contamination, and desiccation, while stopping pain from exposed nerve ends and allowing body fluid evaporation.

Abstract: An adhesive composite is provided which consists of a conformable backing, a pressure-sensitive adhesive which is coated on at least a portion of the bottom surface of the backing, a permanent adhesive reinforcement which acts as reinforcing means for the backing, coated on the bottom surface of the film and a liner which is releasably applied to the adhesive coated surface of the backing. A delivery means may also be provided to allow delivery of the system without touching the adhesive. The permanent adhesive reinforcement is applied to the backing in an amount which is sufficient to provide some reinforcement to the thin film backing so that the composite wall not tend to fold back on itself or wrinkle under ordinary use. Preferably this permanent adhesive reinforcement is applied to the periphery of the backing.
