摘要:
A light-occlusive self adherent eye patch (10) is disclosed comprising an absorbent pad (12) having a nonadherent lower surface (14), a backing (16) having a lower face (18) adhered to the upper surface of the pad (12) and extending outward from the periphery thereof, a light-occlusive pressure sensitive adhesive coating (18) on the lower face of the backing to adhere the patch to the eye socket, and a removable liner (20) protecting the lower surface of the pad and the adhesive prior to use. The pressure sensitive adhesive blocks at least 95 percent of the light of a preselected wavelength impinging on the adhesive.
摘要:
A shelf-stable device for transdermally administering an active pharmaceutical to a patient. The device includes a drug reservoir (16) that contains the drug formulation. In one preferred embodiment of the present invention, the drug reservoir (16) is sandwiched between an upper (18) and a lower (20) solvent barrier film that are made from a material such as a polyester that will not absorb the drug and/or skin permeating enhancing solvent, if any, contained within the reservoir. The drug reservoir and solvent barrier films are encapsulated within a hermetically-sealed compartment (22) that protects the drug formulation from common environmental factors such as water vapor, oxygen, and light which can adversely affect the stability and efficacy of the drug formulation. The hermetically-sealed (22) compartment also prevents the drug formulation from coming into contact with and possibly dissolving the adhesive used to secure the device to the patient's skin. In another particularly preferred embodiment of the present invention, the device's drug reservoir is encapsulated within a hermetically-sealed compartment that is made from (combined) solvent/environment barrier films (70) that serve the dual functions of preventing the device's components from absorbing the drug/solvent formulation from the reservoir, and protecting the drug/solvent formulation from common environmental factors.
摘要:
A topical dressing is manufactured from a strip-shaped assembly of dressing structures. Each such structure has an aperture (9) to receive a topical treatment substance (20) bounded on one side by a layer of skin adhesive (7) protected by a peel-off backing paper (8) and sealed on its other side by a foil strip (1). The adhesive layer (7) may be carried on a strip of microporous material (10) which is secured to the foil (1). The aperture (9) may be sealed after insertion of the topical substance (20) by a second foil strip (18) which is secured peripherally to the first foil strip (1). The first foil strip (1) may be perforated (15) to permit easy release of the portion of foil supporting the substance (20) and the adhesive coated material (7) so that this can then be bonded to the skin.
摘要:
Disclosed are tapes for medical use, prepared in a one-pass coating operation in which an extensible tape backing is treated simultaneously with LAB material and elastomer. The resultant tapes exhibit release characteristics and elasticity that enable them to be dispensed in the form of a linerless rolls or in pads without deformation or loss of adhesion.
摘要:
Um bei einem Pflaster mit einer eine Vertiefung (116) zur Arzneimittelaufnahme aufweisenden Verbundfolie (114), die mit einer die Vertiefung (116) umringenden Klebstoff-Schicht (150.3) versehen ist, und mit einer die Vertiefung (116) bedeckenden, aufgeklebten Deckverbundfolie (112) eine Optimierung der Galenik unabhängig von Eigenschaften einer das Arzneimittel (118) enthaltenden, in der Vertiefung (116) angeordneten Matrix zu ermöglichen, wird vorgeschlagen, die Vertiefung (116) mittels einer für den Wirkstoff des Arzneimittels (118) durchlässigen, mit der Verbundfolie (114) fest verbundenen Membran (120) zu verschließen und die Deckverbundfolie (112) längs eines zwischen der zentralen Membran (120) und der umgebenden Klebstoff-Schicht (150.3) verlaufenden Ringes hermetisch mit der Verbundfolie (114) zu verbinden. Um ein Verfahren zum Herstellen eines solchen Pflasters, bei welchem zwei separat erzeugte äußere Pflasterteil (112,14) mittels einer inneren Klebstoff-Schicht (150.3) trennbar verbunden sind. anzugeben, das eine rationelle Massenfertigung dieses Pflasters ermöglicht, wird vorgeschlagen, die Klebstoff-Schicht (150.3) als Bestandteil eines inneren, dritten Pflasterteiles (120/150) zu erzeugen, der separat von den beiden äußeren Pflasterteilen (112,114), erzeugt und danach mit diesen fest verbunden wird.
摘要:
A medical dressing for covering skin abrasions or lacerations in the form of a bandaging material (10), preferably a single layer of porous, non-woven polyester, having a prossure-sens'rtive adhesive on one surface in marginal areas (12) about the periphery thereof, with a central area (14) free of such adhesive. The dressing is provided in pre-cut sizes with a removable sheet of release liner (16) shaped to cover at least the adhesive-coated areas.
摘要:
The present invention relates to dressings such as bandages improved extensibility. The present invention further relates to dressings comprising an absorbent body and backing layer having improved extensibility.
摘要:
The present invention relates to an adhesive skin patch material, which comprises a polyurethane elastomer film, a pressure-sensitive adhesive layer provided on one side of the polyurethane elastomer film, and a release liner releasably laminated so as to cover the sticky surface of the pressure-sensitive adhesive layer. The polyurethane elastomer film has a thickness of 1 µm to 9 µm, and the pressure-sensitive adhesive layer contains an acrylic-based copolymer and an ingredient in a liquid or pasty state at room temperature.
摘要:
The current invention concerns a multi-layer adhesive tape to compress and contract one or more scars, comprising: ‒ a top layer (4); ‒ a bonding layer (3) adjacent to said top layer (4); ‒ a bottom layer (2) adjacent to said bonding layer (3) and opposite to said top layer (4); ‒ an adhesive layer (1) adjacent to said flexible bottom layer (2) and opposite to said bonding layer (3); and ‒ a first peelable liner (7) at least adjacent to said adhesive layer (1) and opposite to said bottom layer (2), wherein the widths (L') of said top layer (4) and bonding layer (3) are larger than the widths (L) of said bottom layer (2) and adhesive layer (1), and wherein said adhesive layer (1) comprises a rubber-or acrylic-based pressure-sensitive adhesive. The invention further concerns a multi-layer adhesive tape to compress and contract one or more scars, wherein said top layer (4) has a thickness between 20 and 1100 µm.
