A flexible dressing for applying to a tissue site for determining the extent of debridement required to remove non-viable tissue is disclosed. Some embodiments of the dressing may be in the form of a multi-layer drape having an integrated tissue viability indicator system. Some embodiments may also include a system of shapes or a grid pattern printed or embossed on a surface of the drape for providing guidance during an ensuing debridement or amputation procedure.

A protective device configured in accordance with a particular embodiment includes a cover including a first region that extends over a vulnerable site on a patient and a second region that extends over an area on the patient peripheral to the vulnerable site. The first region of the cover is at least generally impermeable to liquid water. The device further includes an adhesive film and a liquid-absorbing element. The adhesive film is configured to form an adhesive bond between the second region of the cover and the patient. The bond has an inner edge portion positioned toward the vulnerable site and an outer edge portion positioned away from the vulnerable site. The liquid-absorbing element is configured to absorb liquid contamination at the outer edge portion of the bond and/or liquid contamination approaching the outer edge portion of the bond when the cover is operably positioned on the patient.

A method of making a wound dressing comprising the steps of: providing an apertured substrate layer; coating the substrate layer with a fluid silicone prepolymer composition; thermally partially curing said silicone prepolymer composition to form a partially cured silicone coating on the substrate; laminating the coated substrate layer to a base layer to form a laminate having said partially cured silicone coating in contact with a surface of the base layer; followed by exposing the laminate to ionizing radiation, to further cure the partially cured silicone coating and to bond the silicone coating to said surface of the base layer. The radiation cure results in strong bonding between the siliconized substrate and incompatible base layers such as polyurethane foams. Also provided are wound dressings obtainable by the process of the invention.

The present disclosure comprises a multi-component dressing for securing an enteral access device, for example, a gastrosnootomy, jejunostomy, cecostomy or vesicostomy button or a gastrostomy tube, or a parenteral access device, and can comprise one or more of an adhesive layer, an absorptive layer and a securement layer to engage the device.

Reduced pressure wound therapy is performed on a sacral region of a patient using an adhesive dressing comprising a flexible planar layer and a non-planar fold-sealing region configured to seal to the intergluteal cleft of a patient. The fold-sealing region is located on an outer edge of the adhesive dressing and comprises a tapered configuration.

A fluid dispensing adhesive strip is presented. The fluid dispensing adhesive strip includes a backing layer having a first side and a second side, an adhesive that is disposed on at least a portion of the second side of the backing layer, and a packet that is disposed on the backing layer that includes a dispensable fluid and an activation mechanism that permits selective dispensing of the dispensable fluid. The packet can include multiple chambers configured to contain the same or different fluids, and channels associated with the chambers for dispensing the fluid when the activation mechanism is activated. The activation mechanism can be a tear-away strip, and can include perforations, serrations, and scoring to facilitate activation. Release strips in communication with the adhesive can releasably detach from the adhesive enabling the fluid dispensing strip to be applied and secured to an object or person.

Provided are buffered adhesive compositions comprising a high molecular weight non-neutralized polymeric acid and a high molecular weight partially neutralized polymeric acid and products such as wound dressings and ostomy skin barriers incorporating the compositions.

A wound dressing includes a perforated film layer, a hydrophilic foam layer, a drape layer, and superabsorbent projections. The perforated film layer is configured to engage a wound bed and has a first side and a second side, the second side configured to face the wound bed. The hydrophilic foam layer also has a first side and a second side, the second side configured to face the first side of the perforated film layer. The drape layer also has a first side and a second side, the second side configured to face the first side of the hydrophilic foam layer. The hydrophilic foam layer also has a plurality of superabsorbent projections fixed to and extending from the first side of the hydrophilic foam layer towards the second side of the drape layer. The drape layer further has a first drape and a second drape, the first drape comprising an adhesive-coated ring configured to peripherally surround and overlap the second drape.

A dressing for use in protectively covering and isolating a medical device placed on and/or through the skin surface of a patient is disclosed. Examples of such devices include infusion needles for accessing subcutaneously implanted access ports, catheters of various types and purposes, insulin infusion needles, etc. In one embodiment, a dressing for covering a medical device on a skin surface of a patient is disclosed and comprises a dressing portion that is configured to rest against a skin surface of a patient, with the dressing portion defining a hole, and a polymeric cover film that is at least indirectly attached to the dressing portion. The cover film includes a pliable domed portion aligned with the hole of the dressing portion. The pliable domed portion defines a cavity that is configured to receive therein the medical device when the dressing is placed on the skin of the patient.
