Patent number: 8235955Abstract: An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are moved by a device (which may be a single pump or two pumps) for moving fluid through a flow path which passes through the dressing and a means for providing simultaneous aspiration and irrigation of the wound, and means for stressing the wound bed and optionally tissue surrounding the wound. The former removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing over the wound bed. The latter promotes wound healing. The dressing and a method of treatment using the apparatus.Type: GrantFiled: April 27, 2006Date of Patent: August 7, 2012Assignee: Smith & Nephew PLCInventors: Patrick L. Blott, Edward Y. Hartwell, Julian Lee-Webb, Derek Nicolini

Patent number: 5633007Abstract: An adhesive dressing suitable for moist wounds includes a first layer comprising a substrate having a layer of pressure sensitive adhesive on a wound facing surface and a second layer comprising a moisture vapour permeable continuous film. The second layer is attached to the non wound facing surface of the first layer at spaced apart intervals thereby to form a plurality of discrete cellular voids between said first and second layers. The first layer has apertures therein to allow passage of liquids therethrough into the cellular voids and total area of the dressing defined by the cellular voids is from 20% to 80% of the total operable area of the dressing.Type: GrantFiled: March 2, 1995Date of Patent: May 27, 1997Assignee: Smith & Nephew PLCInventors: Julian Webb, Christopher I. Reed, Mark F. Smith, David F. Farrar, Patrick L. Blott, David Houldridge, Anna F. MacFarlane, Selvarajah Sivshanker

Patent number: 5531667Abstract: A plurality of layers of a bandage can be jointed together at edges thereof to provide a casting bandage, which can then be coated/impregnated with a resin.Desirably the layers are formed from tubular members which are edge-stitched together.Type: GrantFiled: February 17, 1994Date of Patent: July 2, 1996Assignee: Smith & Nephew plcInventors: Julian A. Webb, Patrick L. Blott
-
Patent number: 5514080Abstract: A casting system for application to a body portion, having an outer layer tubular substrate carrying a water hardenable resin wherein the substrate is at least 2 mm thick and an inner layer having an undercast padding material that includes hydrophobic fibers or yarns.Type: GrantFiled: January 3, 1994Date of Patent: May 7, 1996Assignee: Smith & Nephew PLCInventors: Patrick L. Blott, Julian A. Webb

Patent number: 5474525Abstract: A tubular undercast padding for a body immobilising cast comprises a conformable, elastically extensible material which material comprises a lofted non-woven fabric. The lofted non-woven fabric may be rendered extensible by forming as a folded or creped layer on a supporting layer of an elastically extensible material.Type: GrantFiled: December 26, 1991Date of Patent: December 12, 1995Assignee: Smith & Nephew p.l.c.Inventor: Patrick L. Blott

Patent number: 5409472Abstract: A conformable wound dressing is produced which comprises a polymeric foam absorbent layer, a continuous or discontinuous adhesive layer covering the body facing surface of the absorbent layer except for a wound contacting area which is free of adhesive and a layer of a liquid impervious moisture vapor permeable material disposed over substantially all or the entire surface of the absorbent layer opposite the body facing surface. The wound dressing may have a discontinuous intermediate layer coextensive with the absorbent layer disposed between the absorbent layer and the adhesive layer. Preferably, more than 50% of the absorbent layer is free of adhesive or when the adhesive is placed on the intermediate layer, more than 50% of the absorbent layer and the intermediate layer are free of adhesive.Type: GrantFiled: April 5, 1993Date of Patent: April 25, 1995Assignee: Smith & Nephew plcInventors: David A. Rawlings, Patrick L. Blott
-
Patent number: 5380260Abstract: A moisture vapor permeable, water impervious padding including sheets or strips of a lofted non-woven fabric having wax, silicone resin or fluorinated polymer at a surface layer thereof. The sheet or strip may be formed into a tube and contain an elastic component in the circumference to result in an elastically extensible tubular undercast padding.Type: GrantFiled: November 9, 1993Date of Patent: January 10, 1995Assignee: Smith & Nephew plcInventor: Patrick L. Blott

Patent number: 5328450Abstract: An absorbent device which comprises an absorbent layer having an apertured contoured polymer film attached to a surface, wherein this surface is provided with a plurality of depressions which communicate directly with the apertures in the film. The device may be produced by separating the polymer film and a carrier material which have been formed into a laminate having impressed therein raised areas defining, for example, the strands of net and depressed areas such that upon separation the depressed areas of the film remain attached together with associated portions of the attached absorbent, to the carrier, leaving the raised areas attached to the remainder of the absorbent.Type: GrantFiled: September 27, 1993Date of Patent: July 12, 1994Assignee: Smith & Nephew plcInventors: Mark F. Smith, Patrick L. Blott

Patent number: 4990144Abstract: A non-adherent wound dressing comprising a film which contains depressions over the wound contacting area of the dressing is described. The depressions contain a viscous pharmaceutical composition which is suitable for topical application to the skin and which preferably contains from 1 to 12.5% by weight of antibacterial agent. In a preferred form of the dressing each depression has an aperture at its apex whereby transmission of wound exudate through the dressing to an absorbent placed on the non-wound contacting surface of the dressing is permitted while at the same time the pharmaceutical composition may release its medicament to the environment of the wound.Type: GrantFiled: June 8, 1989Date of Patent: February 5, 1991Assignee: Smith and Nephew Associated Companies plcInventor: Patrick L. Blott
