Adhesion on demand articles include a layer of adhesive and a backing layer in contact with the adhesive layer. The backing layer includes a plurality of cuts, where the plurality of cuts are gaps but the gaps are not visible to the naked eye when the adhesive article is in an unstressed state, but in a stressed state, at least some of the cuts become gaps that permit adhesion of the first major surface of the adhesive layer to a substrate surface.

Provided is a medical tape that has a high effect of alleviating a persistent skin irritation during an application duration caused by a residual shrink force associated with a forming shrinkage. A medical tape includes an elastic base member portion film-formed of a solution polymer and having an elastic function, a restoring force preserving portion having inelastic, flexible, and restorable functions, an adhesion portion having a function to apply and hold the elastic base member portion on a skin, and a release portion having a function to protect the adhesion portion. The restoring force preserving portion, the elastic base member portion, the adhesion portion, and the release portion are laminated in this order from an upper layer.

A covering sheet for covering a skin adhesive surface of a device for holding a tracheostoma device over a tracheostoma of a patient may include a central/medial element for covering the central/medial part of the skin adhesive surface of the device. The covering sheet may include first and second elements arranged laterally of the central/medial element. Lateral peripheral borders of the central/medial element may be positioned adjacent medial peripheral borders of the first and second elements. The peripheral borders may be defined by division lines.

Provided herein is a system and method for trauma-free application and removal of light deactivated adhesive drapes. One aspect provides a system comprising a drape, at least one photosensitive adhesive portion having a release agent, and at least one acrylic and/or polyurethane adhesive portion, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a removable blocking layer to prevent the photosensitive adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing the removable blocking layer and applying light to the drape to deactivate the photosensitive adhesive portion and promote easy, clean, and less painful removal of the drape. When the photosensitive adhesive portion is deactivated, the acrylic and/or polyurethane adhesive portion maintains adhesion between the drape and the tissue until removal of the drape.

A holder for securing a venous access device to a patient may include a flexible substrate having an upper surface, a lower surface, and an outer perimetal surface. An adhesive layer may overlay the lower surface of the flexible substrate. The adhesive layer may have an adhesive for adhering to skin of the patient. The holder may further include a hydrophilic matrix integrated into at least a portion of the adhesive layer, at least one solvent reservoir disposed on the upper surface of the flexible substrate, and a connector secured to the outer perimetal surface. The connector may have a first end for connection to a needle assembly and a second end for connection to an IV fluid line.

Methods and compositions for securing to and removing adhesive tapes from substrates, e.g., delicate substrates such as skin, are described. The methods include providing an adhesive tape comprising an adhesive layer and a support layer in contact with the adhesive layer. A first adhesion level between the adhesive layer and the support layer is, or can be controlled to be, less than a second adhesion level between the adhesive layer and the substrate. The methods further include applying the adhesive tape to the substrate by contacting the adhesive layer to the substrate while the support layer remains in contact with the adhesive layer; and removing the support layer from the substrate by separating the support layer from the adhesive layer.

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.

Compositions containing a surface active agent and a sub-lethal amount of an antimicrobial agent and methods for using such compositions are provided herein.

A wound dressing for a burn or open wound comprises a body of a foam material with an open center area. The thickness of the foam body creates a zone for air circulation and prevents contact with the wound. This may have a mesh, gauze or other air permeable cover over the open center area.

Medical tape suitable to be adhered onto a skin wound for healing of the skin wound or onto a scar for suppressing a thickening, an expansion and an extension of the scar after healing of the wound. The medical tape includes a flexible and stretchable substrate consisting of a plastic film or foil; a release paper which is adhered to one side of the substrate via a pressure-sensitive adhesive layer; and a peelable support consisting of two sheets of plastic films which are adhered to another side of the substrate via a silicone-coating layer and a slightly adhesive layer, in that order. The two sheets of plastic films are butted with each other at the midpoint of a longitudinal direction of the substrate, and over a widthwise direction of the substrate. The medical tape advantageously applies a shrinking force only to a wound surface or a scar surface.
