A bandage has a first sheet overlying a wound and located adjacent to it and a top sheet overlying the first sheet. The first sheet has a plurality of discrete passageways overlying the wound and adapted to communicate negative pressure established by a negative pressure source to the wound.

Wound treatment apparatus

A wound therapy combination comprising a suction head and a surgical drape. The suction head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The second face is formed with projections that define flow channels for facilitating flow of liquids to the aperture.

Surgical drape and suction head for wound treatment

The invention relates to a portable wound treatment apparatus for stimulating the healing of superficial wounds. The apparatus comprises a housing (210) containing a suction pump and a canister for containing fluids drawn from the wound. The housing is supported on a harness or belt (216, 218) worn by the patient and is connected to a porous dressing at the wound site by a catheter.

Portable wound treatment apparatus

Apparatus for the application of topical negative pressure therapy to a wound site is described, the apparatus comprising: a wound contacting element for retaining wound exudate fluid therein; a wound covering element that provides a substantially airtight seal over the wound contacting element and wound site; a vacuum connection tube connecting a wound cavity to a vacuum source; and a vacuum source connected to a distal end of the vacuum connection tube.

Vacuum assisted wound dressing

A wound dressing member is provided for use in a vacuum bandage connected to a vacuum source. The wound dressing member is also provided for use with a wound having a wound surface. The wound dressing member includes a wound facing surface adapted to be in contact with and generally conform to the wound surface and a plurality of discrete holes formed in the wound facing surface. The member further includes a port configured to communicate with the vacuum source and with each hole formed in the wound facing surface. The wound dressing member further includes a stand-off having interconnected portions coupled to the wound facing surface and configured to provide a space between the wound facing surface and the wound surface.

Vacuum therapy and cleansing dressing for wounds

Apparatus for selectively blocking passage of lipids in a liquid flow path A baffle interposed in the liquid flow path is of nonpolar material and is arranged to permit liquid flow therethrough with contact of said liquid with the nonpolar material of the baffle for removing lipids from the flow In one embodiment, the baffle is interposed between the wound drain connection and vacuum connection in a drain reservoir and protects the hydrophobic filter which is at the end of the vacuum passage communicating with the interior of the drain reservoir bottle The baffle enables use of a nonpolar material for the hydrophobic filter and avoids coating and thereby clogging of the hydrophobic filter by lipids in the liquid drained from a wound
