Methods and apparatuses are disclosed relating to the creation and use of bespoke wound fillers and other wound treatment apparatuses. Some embodiments provide for the creation of bespoke wound fillers based on characteristics of a wound. Certain embodiments also include the use of bespoke wound fillers in combination with negative pressure to treat a wound.

A dressing for treating tissue with negative pressure may be a composite of dressing layers, including a release film, perforated gel layer, a perforated polymer film, a manifold, and an adhesive cover. A method of manufacturing the dressing may comprise providing a first layer, such as the gel layer, on a substrate, perforating the first layer on the substrate to create a plurality of apertures in the first layer, and creating an index of the plurality of apertures in the first layer. A laser can be calibrated based on the index. A second layer, such as the polymer film, may be coupled to the first layer, and a plurality of slots can be cut in the second layer with the laser. Each of the slots can be cut through one of the apertures in the first layer based on the index.

Proposed is an improved cast used for covering an affected area of a patient having a fracture or dislocation or diabetic patient to keep the continuity of the affected area and the unaffected area, and to protect the affected area from external shock.

A negative pressure wound dressing and method of making same includes a flexible foamed polymeric material having a plurality of channels or holes formed by a laser within the cellular structure thereof, the flexible foamed polymeric material for use to contact a wound contact surface in negative pressure wound treatment.

An applicator is disclosed for applying a treatment solution to a treatment site of a patient. The applicator can include an applicator housing comprising a treatment solution reservoir. A cartridge can be removably disposed in the housing. The cartridge when arranged in the housing can be in fluid communication with the treatment solution reservoir. The cartridge can include an electrostatic module for electrostatically charging the treatment solution in the treatment solution reservoir; and a nozzle for applying the treatment solution.

Apparatus and method for producing absorbent structures with absorbent layers with channel(s) without absorbent material, using a first moving endless surface with specific raised strip(s) and a second moving endless surface with specific mating strip(s).

A wound dressing, a method of manufacturing a wound dressing, and a method of treating a patient are disclosed. The wound dressing may include an absorbent layer for absorbing wound exudate; and an obscuring element for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use.

A method of manufacturing a tissue interface for a reduced pressure tissue treatment system is provided. The method includes foaming a plurality of polymer particles to form a porous polymer. The method also includes sintering the porous polymer to form a sintered porous polymer. The method further includes texturing the sintered porous polymer. A system to provide reduced pressure at a tissue site is provided. The system includes a cover configured to form a seal over the tissue site. The system also includes a reduced-pressure source configured to provide reduced pressure through the cover at the tissue site. The system further includes a tissue interface configured to be disposed underneath the cover at the tissue site and comprising a porous polymer that is formed from one or more polymer particles that may be foamed and textured.

Described herein are wound dressings comprising: an absorbent layer capable of absorbing a given volume of fluid and comprising a first sorption zone comprising a first density of fibers and a second sorption zone comprising a second density of fibers higher than the first density; a hydrophilic foam layer coupled to the absorbent layer; and a backing layer extending beyond the absorbent layer and the hydrophilic foam layer to define a backing layer margin, wherein, upon exposure of the absorbent layer to a saturation threshold of wound exudate, the first sorption zone expands to a first thickness and the second sorption zone expands to a second thickness that is visually distinguishable from the first thickness. Methods of manufacturing the wound dressing and of eliminating, minimizing, or reducing edema are also described herein.

An emergency hemostatic head trauma bandage cap with a strap system and method of use, which, when applied to the head, delivers minimal pressure to control bleeding, doesn't compromise cervical spine immobilization, allows for fast and effective application of cooling gel to control intracranial/internal swelling or hot packs to prevent hypothermia in non-trauma situations, doesn't come apart during treatment and transport, and doesn't require a caregiver to re-wrap the dressing.
