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.

Disclosed is a porous structure including water-soluble chitosan; and a carboxymethyl cellulose-based compound, wherein a weight ratio of the water-soluble chitosan and the carboxymethyl cellulose-based compound is from 65:35 to 25:75, and a process for preparing the same.

A treatment system for applying negative pressure therapy and fluid instillation treatment to a tissue site, particularly an abdominal tissue site, is disclosed. In some embodiments, the treatment system may include a dressing member, a plurality of fluid removal pathways, a fluid instillation matrix, a drape, a negative-pressure source, and a fluid instillation source. Instillation fluid may be delivered from the fluid instillation source to the tissue site through the fluid instillation matrix, and negative pressure may be communicated and fluid withdrawn from the tissue site through the plurality of fluid removal pathways.

A wound dressing includes a dressing member or body which has a wound-facing side intended to be placed adjacent a wound, such a surgical wound. The wound-facing side of the wound dressing is provided with a plurality of microstructures in the form of denticles. Each of the denticles includes a body that extends from a base of the denticle laterally over, but not connected to, the dressing member. The denticles are arranged in an overlapping manner such that the body of one denticle overlaps the body of one or two other adjacent denticles. The denticles create a microstructured surface that resists bioadhesion, and which, upon flex of the wound dressing, create mechanical interference with each other that can dislodge organisms that manage to adhere to the wound-facing side of the wound dressing in spite of the microstructured surface.

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 is provided herein comprising a composite of dressing layers, including a release film, a perforated coated polymer film, a manifold, and an adhesive cover. Additionally, a method of manufacturing the dressing may comprise applying a cross-linkable polymer to a polymer film, curing the cross-linkable polymer to a gel layer to form a coated polymer film, and perforating the coated polymer film to form fluid restrictions, such as slits and/or slots, though the coated polymer film.

Tubular bandage, in particular a finger or toe bandage which is formed as a tube comprising an outer layer which is connected to an inner layer, and wherein the outer layer has a diameter and an elasticity such that the bandage can be clamped adhesive-free around the body part to be treated, in the particular, said finger or said toe, and wherein the inner layer is made of an elastic wound-protective material, wherein said outer layer is made of an air-permeable and water-repellent material, and wherein, at the open endings, said outer layer extends in the longitudinal direction over the inner layer over a distance of more than 0.5 mm, such that the outer layer touches the body part to be treated, in particular a finger or toe, with its endings when applied.

The present application provides a medical multi-layer product comprising a layer comprising nanofibrillar cellulose, and a layer of gauze. The present application also provides a medical product comprising the medical multi-layer product, and a cosmetic product comprising the medical multi-layer product. The present application also provides a method for preparing a medical multi-layer product, the method comprising providing a filter, providing a dispersion comprising nanofibrillar cellulose, providing a gauze, applying the dispersion onto the filter, applying the gauze onto the dispersion, and dewatering the structure through the filter to obtain the medical multi-layer product.

The present invention deals with a cellularized dressing and the method for production of such a dressing, where this method preferably comprises a step of bioprinting of cells.
