In some illustrative examples, a medical drape suitable for treating a tissue site may include an adherent surface including first adherent force profile oriented along a first axis and a second adherent force profile oriented along a second axis. The first adherent force profile may have an average force less than an average force of the second adherent force profile. Other apparatuses, systems, and methods are also provided.

A wound dressing is disclosed that has a moisture-transmissible backing layer, an absorbent adhesive gel, and a porous layer. The moisture-transmissible backing layer has a first major surface, a second major surface, a backing layer perimeter, and a first opening. The second major surface has a first adhesive disposed thereon proximate the backing layer perimeter. The absorbent adhesive gel is adhered to at least a portion of the second major surface of the backing layer. The absorbent adhesive gel comprises an adhesive gel perimeter and a second opening. The first opening overlaps at least a portion of the second opening. The porous layer has a first side, a second side, a porous layer perimeter. The first side of the porous layer is adhered to the absorbent adhesive gel. The backing layer overlaps at least a portion of the adhesive gel perimeter. The absorbent adhesive gel overlaps at least a portion of the porous layer perimeter.

An adhesive wound dressing is disclosed herein. The adhesive wound dressing comprises a first layer that is an outer layer. A second layer is a resilient layer and affixed to an inner surface of the first layer. A third layer is an inner gauze dressing and affixed to an inner surface of the second layer, wherein the first layer, the second layer, and the third layer define a generally tubular configuration having an open end and a closed end. An adhesive layer may be applied adjacent to the open end for configured securing the adhesive wound dressing to a wounded body part subsequent to the wounded body part being inserted within the open end.

Provided herein is a system and method for coupling a wearable therapy system to a dressing and detaching the wearable therapy system from the dressing. One aspect provides a system including a drape with a switchable adhesive layer and a therapy system adhered to the drape via the switchable adhesive layer. The therapy system includes one or more radiation sources that can emit radiation wavelengths (e.g., light or electromagnetic waves) to impinge upon the adhesive and deactivate the adhesive when it is desired to remove the therapy system from the drape.

In some illustrative examples, a medical drape suitable for treating a tissue site may include an adherent surface including first adherent force profile oriented along a first axis and a second adherent force profile oriented along a second axis. The first adherent force profile may have an average force less than an average force of the second adherent force profile. Other apparatuses, systems, and methods are also provided.

A wound dressing is provided. The dressing includes a moisture-transmissible backing layer having a first major surface, a second major surface, a backing layer perimeter, and a first opening; an absorbent adhesive gel adhered to the second major surface of the backing layer, the absorbent adhesive gel comprising an adhesive gel perimeter; and a porous layer having a first side, a second side, and a porous layer perimeter. The second major surface has a first adhesive disposed thereon. The first side of the porous layer is adhered to the absorbent adhesive gel. The porous layer is configured to facilitate passage of fluid to the first opening. One-hundred percent of the adhesive gel perimeter is overlapped by the backing layer. At least 50% of the porous layer perimeter is overlapped by the absorbent adhesive gel.

In order to provide an elastic medical tape having an especially excellent elastic function and a high effect of alleviating persistent skin irritation during application duration caused by an application-duration shrink force, and applicable to skin that hypersensitively reacts to even insignificant irritation, disclosed is a medical tape for alleviating persistent skin irritation during application duration caused by an application-duration shrink force of an elastic base member of an elastic medical tape, the medical tape including: an elastic base member portion (1) having an elastic function; an adhesive portion (2) having a function of applying and holding the elastic base member portion (1) to skin; and an anti-expansion portion (3) having a function of preventing expansion of the elastic base member portion, the anti-expansion portion (3) overlying the elastic base member portion (1), wherein, after in a manufacturing process, the elastic base member portion (1) and the anti-expansion portion (3) are laminated while the elastic base member portion is in a slacked state or in a not-pulled state, and in the manufacturing process, the elastic base member portion (1) and the anti-expansion portion (3) are laminated while a residual shrink force is not generated in the elastic base member portion (1) in order to reduce the residual shrink force of the elastic base member portion (1), the adhesive portion (2) is applied to skin while preventing expansion of the medical tape, and the anti-expansion portion (3) is then removed.

A dressing for applying pressure to a patient target site is provided. The dressing includes an elastic spacer longitudinally extending between first and second substrates. The elastic spacer is configured to be selectively moved between the first length and a second length. The second length is longer than the first length. A triggering element, when present, selectively maintains the elastic spacer at the second length and selectively prevents the elastic spacer from moving toward the first length. Portions of the triggering element are sequentially removable such that as each portion of the triggering element is removed, the elastic spacer sequentially moves from the second length toward the first length. The sequential movement of the elastic spacer from the second length toward the first length responsively urges the first and second substrates longitudinally toward one another to apply a predetermined amount of longitudinal force to the patient target site.

A multi-layered thin film adhesive substrate is disclosed, comprising at least three coextensive layers and an adhesive layer. The thin film substrate is resilient, but remains flexible for accurate and smooth application, in uses such as securement of medical dressings and devices.

A dressing is described having a backing layer, an (absorbent) pad, an adhesive coating and a release liner. The release liner is releasably attached to the adhesive coating. The release liner is configured to stiffen up and protect protrusions and/or border portions of the dressing that may otherwise be wrinkled, folded, kinked or otherwise damaged or impaired prior to (transportation or storage) or during application at the point-of-use. The dressing can be used for wound treatment. The dressing can prevent shearing and/or friction from causing (deep tissue) skin damage.
