A medical dressing is described that includes: a porous layer having a first side and a second side; a first coating extending along at least a portion of the surface area of said first side of said porous layer; a second coating extending along said first side of said porous layer, said second coating comprising a pattern of through openings; wherein said first coating extends along at least those portions of the surface area of said first side of said porous layer that coincide with the through openings of said second coating and wherein said first surface of said second coating extends in a plane (B) that is farther away, in the vertical direction, from the first side of said porous layer, than the corresponding plane (A) defined by the first surface of said first coating.

A dressing including a film which is impermeable to fluids and permeable to water vapor, and the entire surface of which is covered by a perforated reinforcement coated with a medically acceptable adhesive which is the same or different on each of the faces thereof, the face opposite to the face in contact with the impermeable film of an adhesive being partially covered by an absorbent pad, The dressing further includes a layer for distributing the fluids which is positioned between the impermeable film and the perforated reinforcement.

Embodiments disclosed herein are directed to the treatment of wounds using negative pressure. Some embodiments disclosed herein provide for a foam pad, which may be suitable for use in abdominal wound sites, and which may be sized in a dimensionally-independent manner. Additional embodiments provide for a wound contact layer, as well as a system for the treatment of abdominal wounds.

A two layer bandage with a hole or opening larger than the wound area for a first layer in contact with the skin is shown and a second layer which carries an absorbent portion cover wound just above the open portion of the first layer. The absorbent is imbedded or attached in the body of the second layer such that the absorbent portion of the bandage can be replaced without disturbing the wound.

The present invention is directed to an absorbable hemostatic patch that utilizes a biocompatible fibrous, fabric substrate that is melt-blown and napped or loosened at the surface, with the substrate having a low-profile, high flexibility, strength and porosity that is suitable for coating cross-linkable active molecules and ultimately effective for use as a hemostat in situations of problematic bleeding.

Disclosed embodiments relate to apparatuses and methods for wound treatment with ultrasound. In certain embodiments, a therapeutic ultrasound wound treatment apparatus includes a wound dressing configured to be positioned over a wound to provide a substantially fluid impermeable seal over the wound and a transducer to deliver therapeutic ultrasound to tissue. The therapeutic ultrasound wound treatment apparatus may further include a wound contact layer configured to be positioned in contact with the wound, a transmission layer positioned above the wound contact layer, an absorbent layer positioned above the transmission layer and configured to absorb wound fluid, and a backing layer positioned above the absorbent layer and including an orifice. Also disclosed are multiple parameters for the therapeutic ultrasound signal.

A dressing for treating a tissue site with negative pressure including a foam member, a sealing layer, and a cover. The foam member may include a felted portion extending a depth into a surface of the foam member and a non-felted portion. The sealing layer may include a treatment aperture and a first plurality of perforations around the treatment aperture. The felted portion may be configured to contact the tissue site through the treatment aperture. A second plurality of perforations may be formed through the felted portion. At least one of the second plurality of perforations may be exposed to the tissue site through the treatment aperture. The cover may include a film disposed over the foam member and coupled to the sealing layer around the foam member and an adhesive disposed adjacent to the second plurality of perforations.

A breathable medical gauze patch includes at least one bandage body coupled with at least one ply of gauze or similar to, which not only helps wounds heal fast, but also prevent infections and potential complications. The at least one bandage body includes an adhesive on the underside that permits mounting about the wound site of a user/recipient. The at least one ply is disposed about a bandage aperture of the at least one bandage body. The at least one ply permits aeration therethrough to the wound site and facilitates absorption of any seepage of the wound while protecting the wound from the exterior environment. Further, the at least one ply may include multiple layers of sterilized medical grade gauze, a gel and an adhesive that allow the present invention to be efficiently and effectively applied to various deep or shallow wounds for facilitating speedy healing of the wounds.
