  • Patent number: 11191484
    Abstract: Various sensor tapes can improve securing of a non-invasive optical sensor to a surface of a medium for taking noninvasive measurement of characteristics of the medium. The sensor tape can taper from a wide end to a narrow end. The sensor tape can transition from a wide portion to a narrow portion in a step-like change or slope. The sensor tape can have staggered portions. The various tapes can be used with an L-shaped sensor. The various tapes can increase contact surface between the surface of the medium and an adhesive side of the tape so as to reduce motion-induced noise.

  • Patent number: 10308004
    Abstract: Methods of forming laminating adhesive articles include providing a multi-layer article, an embossing tool with a structured surface, and a support surface tool. The multi-layer articles include a substrate, an adhesive layer, and a liner or may just include an adhesive layer and a liner. The multi-layer article is placed between the structured surface of the embossing tool and the support surface tool. The embossing tool is pressed against the liner and the support surface tool is simultaneously pressed against the substrate by applying pressure or a combination of pressure and heat. The pressing causes the structures on the surface of the embossing tool to distort the liner and the adhesive layer and the support surface tool modifies the surface of the substrate. The distortion in the liner is retained upon release of the applied pressure. Upon removal of the liner from the adhesive layer, the structures on the adhesive layer are unstable, but do not immediately collapse.

    Abstract: A medical adhesive bandage and delivery system including a medical adhesive bandage and a package. The bandage has a backing, an adhesive on a first surface of the backing, and a pad proximate the first surface of the backing. At least one line of separation (for example, a line of perforations) is provided in the backing and the pad to facilitate selective manual separation of the bandage into more than one bandage. The package may include a release area or liner, with the adhesive on the medical adhesive bandage releasably adhered to the release area or liner. The package preferably tends to retain the bandage therein when the package is torn and the bandage is separated along a line of separation.

  • Patent number: 5910125
    Abstract: The dressing system of the present invention provides, in one aspect, a composite dressing that allows a wound to be dressed in one easy step and redressed without disturbing the wound. The composite dressing comprises a contact component having a bottom side facing a wound, and a top side. A dressing component is releasably attached to the top side of the contact component such that the dressing component can be readily separated from the contact component if pulled relative to the contact component. The contact component can remain on the wound to prevent disturbance, and another composite dressing or dressing component can be applied to the contact component.

  • Patent number: 5902260
    Abstract: A thin film wound dressing is disclosed in which a thin, transparent, vapor-transmitting elastomeric film is coated along its underside with a suitable pressure-sensitive adhesive for securing the dressing to a patient's skin. Prior to use, the adhesive layer is protected by a removable release liner. The opposite (upper) surface of the film has a foraminous backing layer of flexible and stretchable material secured (preferably removably) thereto. The stretchable backing layer has a multiplicity of wide openings or foramina separated from each other by foam strip portions, and at least some of the strip portions preferably terminate in free ends along a peripheral edge of the film.

  • Patent number: 5810756
    Abstract: A perforated medical adhesive tape has a tape backing layer formed from flexible sheet material, e.g., plastic film, and a pressure-sensitive adhesive layer for bonding the adhesive tape to the skin of a patient. The pressure-sensitive adhesive layer is flexible, deformable, elastic and has a permanently tacky surface. The backing layer has a planar outer surface with a multiplicity of upwardly extending protrusions, i.e., minute mounds which are upward deflections in the tape with corresponding upwardly extending, downwardly opening concavities or indentations in its lower surface below each of the protrusions. Each of the protrusions has a pierced opening located at its approximate center. The openings are elevated above the planar surface of the tape, and each opening extends through both the tape backing and the pressure-sensitive adhesive layer to facilitate the diffusion of air and moisture vapor through the tape. The tape is pierced with a multiplicity of heated needles, each having a tapered point.

  • Patent number: 5681301
    Abstract: A disposable absorbent article comprises an absorbent panel and a backing web secured to the panel. A preferred form of the web comprises an apertured film. The web may also include other components on the apertured film, including adhesive. The apertured film is preferably produced from a solid precursor film. The precursor film comprises a copolymer of ethylene and a comonomer polymerized using a single-site metallocene-type polymerization catalyst. The apertured film is formed from the precursor film so that the apertured film has localized deformations and apertures therein. The apertured film exhibits breathability, strength, and flexibility with an elasticity accommodating stretch or elongation and at least partial recovery.

  • Patent number: 5662599
    Abstract: A disposable wound dressing and support unit for delivering a variety of standard gauze pads on top of a wound and providing for a painless access to the wound. The disposable wound dressing and support unit consists of an elongated bidirectional (stretches laterally) wrap which includes a window opening therethrough and disposed along the length of the wrap. The bidirectional wrap is adaptable for conforming to various parts of the anatomy of a patient and includes a releasable hook fastener at one end for securing the end to any portion of the wrap. The wrap is made of a loose weave material. The wound dressing and support unit may be received around the trunk, head, limb, hand and other parts of the anatomy. Also, one end of the wound dressing and support unit may be bifurcated for ease in receipt around various parts of the human anatomy. The window opening may be of different widths, lengths and geometric shapes for application to different sizes and types of wounds.

  • Patent number: 5632731
    Abstract: Disclosed is an improvement in wound dressings comprising an absorbent pad for receiving and retaining wound fluids sandwiched between outer perforated non-adherent films for preventing the dressing from sticking to the wound, the improvement being employing as the absorbent pad a multilayer structure comprising an inner layer of a low density absorbent material for receiving fluids diffusing to the dressing from the wound and an overlying layer of a high density absorbent material for receiving and retaining wound fluids diffusing through the inner layer in order to inhibit skin maceration due to the wetness of the surface area of the absorbent pad adjacent the wound.

  • Patent number: 5633070
    Abstract: An adhesive film for adhesive bandage in which an adhesive is coated on one surface of a nonwoven fabric, characterized in that a film having water vapor permeability and water proofing property is laminated on the opposite surface of the nonwoven fabric. A backing sheet is formed in such a structure that an elastic nonwoven fabric is laminated with a film having water vapor permeability and water proofing property, whereby sufficient flexibility and excellent water vapor permeability are provided and help to keep skin respiration and not only to prevent skin irritation caused by stickiness with perspiration or the like but also to completely prevent permeation of water, a detergent aqueous solution or the like into a pad portion or an affected part and further to prevent infection of a wound with bacteria. The preventions can be more completed by sealing the edge portion of the adhesive bandage via heat-sealing or the like.

  • Patent number: 5613942
    Abstract: This invention relates to an adhesive sheet material, such as an adhesive tape, which is suitable for use on wet surfaces, in particular upon wet skin. The adhesive sheet material effectively binds to the wet surface and moves moisture away from the surface. The adhesive sheet material has a porous backing having opposing sides and is made of non-wettable fibers. The water-insoluble pressure sensitive adhesive is discontinuously coated on one side of the backing to provide areas of the adhesive interspersed with areas of bare backing.
