Foam wound inserts with high-density and low-density regions, methods for making wound inserts, wound-treatment methods, and wound-treatment systems.

A medical dressing is disclosed, the medical dressing has an adhesive layer having a skin-facing surface to adhere the medical dressing to a dermal surface, wherein said adhesive layer comprises a first chemical compound incorporated within said adhesive layer, and wherein at least a portion of said skin-facing surface has a coating comprising a second chemical compound. Also disclosed is a method of manufacturing such a medical dressing.

Dressings, systems, and methods for treating a tissue site on a patient involve allowing liquids from the tissue site or a priming fluid to evaporate and exit the dressing through a liquid-impermeable, vapor-permeable membrane. The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

Foam wound inserts with high-density and low-density regions, methods for making wound inserts, wound-treatment methods, and wound-treatment systems.

A medical dressing (30) is disclosed, comprising an adhesive layer (3) having a skin-facing surface (6) to adhere the medical dressing to a dermal surface, wherein said adhesive layer comprises a first chemical compound incorporated within said adhesive layer, and wherein at least a portion of said skin-facing surface comprises a coating (9) comprising a second chemical compound. Also disclosed is a method of manufacturing such a medical dressing.

Embodiments disclosed herein are directed to the treatment of wounds using negative pressure. Some embodiments disclosed herein provide for a foam pad, which may be suitable for use in abdominal wound sites, and which may be sized in a dimensionally-independent manner. Additional embodiments provide for a wound contact layer, as well as a system for the treatment of abdominal wounds.

The dressing is able to process more liquids than would otherwise be possible without evaporation and potentially to create reduced pressure. Other dressings, systems, and methods are disclosed.

A method, and apparatus for the controlled acceleration, and/or retardation of the body's inflammatory response generally comprises a foam pad for insertion substantially into a wound site, a heating, a cooling pad for application over the wound site, a wound drape or sealing enclosure of the foam pad, the heating, and cooling pad at wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of the controlled acceleration or retardation of the body's inflammatory response. The heating, and cooling provision controls the local metabolic function as part of the inflammatory response.

Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

An elongate wound dressing for packing a wound is described, the wound dressing being substantially planar and having a first longitudinal edge comprising at least one curved edge portion which is curved in the plane of the wound dressing.
