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.

A method for manufacturing a wound dressing having a substrate, and a wound dressing manufactured by such a method are described. The method has a step of providing a sacrificial layer of material to be perforated by means of a hot pin perforator, in order to remove any molten residues on the heated pins of the hot pin perforator, before the same pins are used to make holes in the substrate. The presented method is cost effective, robust and reduces the risk of contaminating substances being embedded in the substrate during the hole making process.

Systems, methods, and apparatuses for forming a multi-function core for a dressing are described. The multi-function core includes a contact layer configured to be positioned adjacent to a tissue site, a wicking layer adjacent to the contact layer, an ion exchange layer adjacent to the wicking layer, an absorbing layer adjacent to the ion exchange layer, a blocking layer adjacent to the absorbing layer, and an odor-absorbing layer adjacent to the blocking layer. The contact layer, the wicking layer, the ion exchange layer, the absorbing layer, the blocking layer, and the odor-absorbing layer are coextensive and formed from a plurality of fibers disposed in a fibrous web. Methods of manufacturing the multi-function core are also described.

A therapeutic device has a bridge portion adapted for releasable adherence to a patch of skin so as to lift the patch of skin above a sensitive underlying treatment site in reducing discomfort or pain associated with tissue compression at the treatment site. The bridge portion is elevated above the treatment site with an exposed adhesive facing the patch of skin to be lifted and/or stretched outwardly. With the application of pressure to elastically deform the device from its original neutral configuration, the bridge portion is brought into contact with the patch of skin, adhering the skin to the adhesive. When the pressure is removed, the device rebounds and generally reassumes its original configuration with the bridge portion lifting the attached patch of skin.

Wound dressings and wound inserts including a porous film layer and at least a channel, forming wound inserts including a porous film layer and at least a channel, and wound-treatment wound inserts.

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.

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 vented wound dressing barrier includes one or more membrane layers with a plurality of vents. The vents are cut along a perimeter of the vents through the one or more membrane layers. Each vent having a connection portion uncut relative to the one or more membrane layers thereby forming a hinge configured to allow the vents to open for drainage when exposed to fluid underlying the vented wound dressing barrier. The plurality of vents is each cut along the perimeter without removal of any of the membrane layer. The one or more membrane layers with the plurality of vents has a surface for covering a wound, the surface area in the absence of a fluid pressing on the vents having no openings or voids which reduce the surface area of a vented wound dressing barrier area covering a wound.

Systems and methods of electrostatically spraying a treatment solution are disclosed that include electrostatically charging, by a cartridge assembled with a handheld portable electrostatic device, a treatment solution. The handheld portable electrostatic device can include a housing, the cartridge removably disposed in the housing. The cartridge can include a cartridge housing, at least one electrode to electrostatically charge and ionize molecules of the treatment solution of the cartridge, and a nozzle positioned at a distal end of the cartridge housing, the nozzle of the cartridge being configured to deliver the electrostatically charged treatment solution and configured to be in fluid communication with an air supply tube in fluid communication with a pump in the housing.

Computer-implemented method for determining a tension value of a limb of a person, the tension value of the limb being used along with a skin value of the limb for production of a custom-tailored compression garment for the limb, the skin value describing the circumference of the limb without any applied compression and the tension value describing the circumference of the limb with the compression garment applying a desired compression, wherein the skin value of the limb is received and the tension value of the limb is calculated from the skin value according to a calculation instruction parametrized by at least one parameter, the parameter being derived from a dataset comprising multiple associated tuples of skin values and tension values.
