摘要:
The present invention relates to a wound dressing 10 that is a porous, self-adhering elastic 14 bandage which may be compressively wrapped around a wound and which is capable of absorbing fluids and wound exudate. A preferred embodiment of the wound dressing 10 is a self-adhering elastic substrate 14 which does not adhere to clothing, hair or skin having a compressive force when extended that provides a therapeutic benefit and which is flexibly attached or fixed to an absorbent layer 12.

Microneedle devices with microneedles having a truncated tapered shape are disclosed. The microneedles of microneedle devices may also have a controlled aspect ratio. Microneedle delivery apparatus are disclosed that include drivers designed to deliver microneedles at velocities that may enhance perforation of the stratum corneum while limiting the sensation of pain experienced at the delivery site.
摘要:
Microneedle devices and methods of manufacturing the microneedle devices. The microneedle devices include microneedles protruding from a substrate, with the microneedles piercing a cover placed over the substrate surface from which the microneedles protrude. The cover and the microneedle substrate together define a capillary volume in fluid communication with the base of each microneedle. One manner of using microneedle arrays of the present invention is in methods involving the penetration of skin to deliver medicaments or other substances and/or extract blood or tissue. Manufacturing methods may include simultaneous application of pressure and ultrasonic energy when piercing the cover with the microneedles.

The present invention is directed to a cold seal package that includes constructions wherein two substrates, or two portions of one substrate, are sealingly engaged to one another using a substantially natural latex rubber-free contact adhesive. The two substrates can be easily peeled apart without substantial damage to the substrates. Furthermore, the substrates cannot typically be resealed, or refastened, once peeled apart. That is, the cold seal formed by the adhesive between the substrates is substantially non-refastenable. Advantageously, a cold seal package of the present invention is particularly well suited for aseptic delivery of packaged goods, such as bandages, dressings, and the like.

An organic particulate-filled adhesive is provided comprising ionomeric particulate dispersed in a polymer matrix containing water-soluble polymer or water-dispersible polymer. The adhesive preferably contains a plasticizer. If desired, in some formulations, the adhesive can contain additives, such as opacifying agents, skin cleansers, skin moisturizers, vitamins, and herbal extracts. The adhesive can have pressure sensitive adhesive properties, although such properties are not necessary. The adhesive can be formulated so as to be useful as a repulpable adhesive and as a cosmetic adhesive.
摘要:
The present application is directed to an assembly comprising an electronic device and a multilayer film. The multilayer film comprises a barrier stack adjacent the electronic device, and a weatherable sheet adjacent the barrier stack opposite the electronic device. The weatherable sheet is bonded to the electronic device.
摘要:
A method and system of winding polymeric film includes providing a length of polymeric film (e.g., low modulus, optical grade film) along with at least one small diameter strand. The film and the strand are simultaneously wound about a cylinder to form a wound roll, with strand being interposed between successively wound layers of film. The strand establishes a gap between the outermost and immediately underlying wound layers of film. The gap facilitates natural movement (e.g., relaxation) of the outermost wound layer relative to the immediately underlying wound layer, thereby compensating for any winding-related stress or tension. The strand can be laterally moved (e.g., oscillated) relative to a width of the film with continuous winding.

The present invention provides an orthopedic casting article having soft edges. In one embodiment, the article comprises a flexible sheet material impregnated or coated with two different resins. In an alternative embodiment, the article comprises an extruded sheet material comprising two different extruded materials. One of the resins or extruded materials is soft or resilient compared to the other resin or material. By selectively providing the softer materials at defined regions of the article the hardness of the region can be adjusted. The article may be in the form of an orthopedic casting tape comprising a fabric backing that is longitudinally impregnated or coated with two different curable resins. A harder, first curable resin is used to coat a longitudinally extending center region of the fabric backing; and a softer, second curable resin is used to coat at least one longitudinally extending edge region of the fabric backing. When wrapped around a limb the softer edge regions may be overlapped to form a soft, comfortable edge of the cured cast.

The present invention provides a method of using novel casting tapes incorporating water soluble liners. The liners of the present invention may be used for a number of purposes including: use as an interlayer film liner in a casting tape article to prevent undesirable resin pooling; use as an interlayer liner to lubricate a casting tape when immersed in water; use in a method of producing a decorative casting tape either by retarding layer-to-layer migration of a colored resin or by transferring a design preprinted on the liner to an adjacent casting tape; use as an interlayer liner in a casting tape article to prevent adhesion between adjacent layers of the article; and use as a release liner to facilitate removal of a roll of casting tape from its package. The liners employed in this invention are rapidly soluble in water and may be provided as a continuous or semi-continuous sheet structure.
