Provided is a dressing, including: a skin-friendly layer, a fluid transport structure, and an upper cover. The skin-friendly layer has first extraction guide holes and first injection guide holes. The fluid transport structure, formed on the skin-friendly layer, has an extraction guide groove, second extraction guide holes, an injection guide groove and second injection guide holes, wherein the extraction guide groove separates from the injection guide groove, the second extraction guide holes are formed in the extraction guide groove and communicate with the first extraction guide holes, and the second injection guide holes are formed in the injection guide groove and communicate with the first injection guide holes. The upper cover, formed on the fluid transport structure, has an extraction hole communicating with the extraction guide groove and the second extraction guide holes, and an injection hole communicating with the injection guide groove and the second injection guide holes.

A medical dressing to treat sucking chest wound, and methods of forming the medical dressing. The methods include the steps of overlaying a cover layer on an intermediate layer and the intermediate layer on a base layer such that openings in the intermediate and base layers are aligned and the cover layer overlays the openings; fusing together the cover layer, the intermediate layer and the base layer by applying an annular welding tool face to at least one of the cover layer and base layer and applying welding energy to the template; and applying an adhesive layer on a side the base layer opposite to the intermediate layer, wherein the adhesive layer extends entirely around the opening.

The present disclosure relates to apparatus for covering a burn or other wound in ways that prevent or limit touching the wound. The present disclosure describes Burn Bandages that may include domes or structures that bridge over a wide range of a burn or wound size. In certain instances these structures may expand in one or more directions as they are adjusted to fit to a particular burn or wound size. Such bridging structures may include airways, openings, or voids that promote air/oxygen flow to the wound as the Burn Bandage sits upon surfaces or pads that contact healthy surrounding tissue while they cover a wound site. The apparatus may be any shape including, yet not limited to, a circle, a rectangle, a square, a hexagon, an octagon, an oval, a cone, a cylinder, have a semi-cylindrical shape, or that have any another geometric shape.

Herein is disclosed a composition comprising: a layer of water-swellable hydrogel, wherein the hydrogel has embedded therein a reinforcement sheet of liquid-water-permeable material, wherein the layer of hydrogel has a wound-facing side and a non-wound-facing side and apertures extend through the layer of hydrogel from the wound-facing side to the non-wound-facing side and through the reinforcement sheet, wherein the mean area of the apertures on at least one of the wound-facing side and non-wound-facing side of the hydrogel is at least 5 mm.sup.2.

A medical dressing including: a flexible base layer including a front surface configured to face a skin of a patient and a back surface opposite the front surface, wherein the flexible base layer includes a first opening; an adhesive layer on the front surface of the base layer; a flexible cover layer entirely covering the opening of the base layer; a flexible intermediate layer sandwiched between the base layer and the cover layer, wherein the base layer, cover layer and intermediate layer joined together along an annular pattern extending entirely around the first and second openings, wherein the annular pattern joints the base layer to the intermediate layer entirely around the first and second openings, and the annular pattern joins the layers around the first and second openings except at slots extending beyond an outer edge of the cover layer and ending before an outer edge of the intermediate layer.

A porous wound dressing for use in negative-pressure therapy is proposed. The wound dressing has an outer edge which defines a substantially oval or rectangular outer shape of the wound dressing with a major axis and a minor axis. The wound dressing has one or more incisions or perforations which together form one or more arc-shaped lines and serve for cutting the wound dressing to size in order to adapt the wound dressing to the shape and/or size of a wound. The one or more arc-shaped lines each extend asymmetrically with respect to the major axis and/or to the minor axis and each enclose, together with a portion of the outer edge, a segment of the wound dressing that is designed for separation from the wound dressing.

In one example embodiment, an apparatus for treating a tissue site may include a contact layer formed from a compressible material. The contact layer may include a plurality of apertures extending at least partially through the contact layer. The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.
