Adhesive constructions include a mammalian skin surface and an adhesive article in contact with the mammalian skin. The adhesive article includes a substrate and an adhesive layer. The adhesive layer in contact with the mammalian skin is a microstructured surface with channels. At least one channel extends to at least one boundary of the adhesive layer. The microstructured surface is a permanently microstructured surface, such that the channels in the surface of the adhesive layer permit transport of fluid.

A pressure monitoring system and method for warning a patient or caregiver that soft tissue pressure has exceeded some predetermined level that over time would necessitate moving the patient to prevent or at least reduce a risk of soft tissue damage. The pressure monitoring system and method utilize a dressing assembly adapted to be applied to or near a surface of the patient's body and generate electrical outputs corresponding to soft tissue pressure sensed at the surface. The dressing assembly includes a pocket formed therein for removable, secured and protected insertion of one or more sensors.

In some embodiments, an apparatus, system, and method for activating a low-adhesion state of a thermal-sensitive tape is described. An example apparatus embodiment includes a light source and a temperature sensor. The light source is configured to illuminate a target area of the thermal-sensitive tape with a first spectrum of electromagnetic radiation to provide heating of the target area. The first spectrum including a first wavelength outside of a visible spectrum. The temperature sensor is configured to detect a second spectrum of electromagnetic radiation to approximate a temperature of the target area. The second spectrum includes a second wavelength different than the first wavelength.

Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing. Fourth, the system may be configured to include an indicator which visually makes clear whether reduced pressure is being applied or not. Fifth, the system is configured to minimize the profile of the dressing system.

An adhesive tape (1) comprises a base material layer, an adhesive layer, and a release material layer, wherein two edges (11 and 12) extending in the longitudinal direction of the adhesive tape include parallel portions (11a and 12a), the length of one of the two edges (11 and 12) is greater than the length of the other, the ends of the two edges (11 and 12) are connected to the ends of two other edges (13 and 14), and two angles formed between the longer edge of the two edges (11 and 12) extending in the longitudinal direction and the two other edges (13 and 14) are acute angles.

A medical drape for use with a reduced pressure system for providing reduced pressure to a tissue site is described. In some embodiments, the drape may include a flexible film, and an adhesive layer coupled to the flexible film. The adhesive layer may include a first adhesive disposed on a first portion of the flexible film in a first pattern. The first adhesive can be configured to secure the flexible film proximate to the tissue site. The adhesive layer generally includes a second adhesive disposed on a second portion of the flexible film in a second pattern. The second adhesive can be configured to seal the flexible film proximate to the tissue site. The first pattern and the second pattern are preferably registered so that the first portion and the second portion are offset to cover substantially different portions of the flexible film.

An adhesive article that remains securely bonded to a substrate until a stimuli is applied. The article may be embodied as an adhesive tape, a bandage, or as other articles. The stimuli may be a change in temperature or application of a reduction that causes a structure within the article to break, creak, or otherwise disrupt to expose the adhesive to a solvent, such as via a difference in Coefficient of Thermal Expansion (CTE) or by exposing the article to a glass transition temperature.

Devices, kits and methods described herein may be for wound healing, including the treatment, amelioration, or prevention of scars and/or keloids by applying and/or maintaining a pre-determined strain in an elastic skin treatment device that is then affixed to the skin surface using skin adhesives to transfer a generally planar force from the bandage to the skin surface. Applicators are used to apply and/or maintain the strains, and some of the applicators are further configured to provide at least some mechanical advantage to the user when exerting loads onto the skin treatment device.

Systems, kits, methods of manufacturing, and a sealing member for creating a sealed space are described. The sealing member can include a film layer and a first adhesive layer coupled to the film layer. The sealing member can also include a second adhesive layer coupled to the first adhesive layer. A plurality of apertures may extend through the second adhesive layer. Each aperture can expose at least a portion of the first adhesive layer through the second adhesive layer. A plurality of polymer particles may be disposed in the first adhesive layer. The polymer particles can be configured to dissolve in response to interaction with a switching solution.

A dressing includes a drape, a pressure-sensitive acrylic-based adhesive disposed on a skin-facing surface of the drape, an island of absorbent material including non-woven superabsorbent fibers, and a wound contact layer. The drape is a thin film capable of maintaining a negative pressure underneath the drape upon application of a vacuum. The island of absorbent material has a smaller area than the drape and is connected with and disposed beneath the sin-facing surface of the drape so as to leave a first margin of adhesive-coated drape around the island of absorbent material. The island of absorbent material further includes interruptions to reduce or eliminate tension or compression in the island of absorbent material as the dressing bends. The wound-contact layer is disposed on a skin-facing side of the island of absorbent material. The wound contact layer is configured not to stick to a wound.
