A wound dressing comprising: an air-impermeable backing sheet having an aperture for attachment of a suction element; an air-permeable screen layer on a wound facing side of the backing sheet; and a substantially air-impermeable hydrogel layer extending across a wound facing side of said screen layer and joined in substantially airtight fashion to a periphery of said backing sheet around said screen layer. Also provided is a wound treatment system comprising a wound dressing according to the invention and a source of suction in fluid communication with said aperture.

An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.

A medical dressing is described for prevention of pressure ulcers. The dressing has a gel pad having a low compressive strength; i.e. from 5 kPa to 60 kPa at a strain of 50%, as measured by the compression test described herein. The dressing reduces the shear and compression forces on the skin and in the underlying the soft tissue layers and prevents or mitigates the onset of pressure ulcers.

Provided herein are fabric materials and debridement devices comprising gel-forming hydrofibres for disrupting a biofilm, loosening, or sequestering unwanted materials from wounds, and uses thereof. In particular, debridement and detection devices for selective and atraumatic removal of unwanted tissues and for detection of a wound infection are provided.

A wound exudate management system includes a pump for generating negative pressure, a dressing for covering and protecting a wound of a user, a tube including an interior lumen, the tube disposed between the pump and the dressing such that the pump and the dressing are in fluid communication via the interior lumen. The dressing includes an adhesive layer for adhering the dressing adjacent the wound, a wound contact layer, a pressure dispersion layer, a plurality of layers of absorbent material disposed between the wound contact layer and the pressure dispersion layer, a backing layer having a first surface and a second surface, the first surface of the backing layer being adjacent, and in contact with, the pressure dispersion layer and the adhesive layer, and a flexible connector disposed on the second surface of the backing layer.

Devices and methods herein remove water from human or animal biological waste fluids using one or more forward osmosis filters. The devices allow for the volume of liquid or semi-liquid waste, including potentially infectious liquid waste, to be filtered to reduce potential exposure of healthcare staff to infectious liquid waste. On a hospital, healthcare staff, or individual patient basis, removing water and concentrating the waste can reduce challenges in management and disposal of the waste. Devices herein use forward osmosis to manage and filter, using one or more suitably sized filter(s), biological fluid exudate from wounds. The devices can be constructed to transport water present in the exudate away from a wound. The wound treatment devices herein not only allow for fluid from wounds to be filtered but also provide structures that can protect wounds from external contaminants, including bacteria and viruses. The wound treatment devices can be incorporated into negative pressure wound therapy systems, if desired.

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.

A dressing for an open wound includes a cover layer dimensioned for positioning relative to a wound bed. The cover layer permits an evacuation of the space around the wound bed such that a sub-atmospheric pressure may be established to stimulate healing and facilitate the removal of fluid from the wound. Multiple performance zones in the cover layer allow the wound dressing to remain in position through repeated cycles of evacuation without placing undue strain on the wound bed. An outer peripheral zone may include a high peal-strength adhesive while an intermediate zone may include a shear resistant adhesive. A central zone may be devoid of any coating to maximize moisture transmission through cover layer.

The present invention is related to an pasting structure that comprises a back-material layer which is formed by attaching the film layer and the porous supporting layer to each other; and a gel layer, one side of the gel layer is bonded to the porous supporting layer and part of the gel layer penetrate pores; wherein the back-material layer and the gel layer closely adhered to each other to form a transparent pasting structure. The pasting structure of the present invention is used as wound dressing which easily observes the wound change and healing status at any time. In the meantime, that provides higher moisture permeability and comfort.

A bandage includes a top film, an absorbent layer and a perforated adhesive lower layer positioned under the absorbent layer for adhering the bandage to a user's skin. The absorbent layer includes at least one incision that improves the flexibility of the bandage.
