Filed:

Nov 1, 1993

Appl. No.:

8/144003

Inventors:

James Vernon Cartmell - Xenia OH
Wayne R. Sturtevant - Centerville OH
Michael Lee Wolf - West Milton OH

Assignee:

NDM, Inc. - Dayton OH

International Classification:

A61F 1300
A61F 1500

US Classification:

602 43

Abstract:

A sterile wound packing material and package therefor is provided, which wound packing is flexible and conformable to deep and/or irregular shaped wounds, is compact and easily dispensed, and which can be stored indefinitely. The wound packing may also be used for absorbing wound exudate and immediately discarded or may be designed to remain in place for extended periods during healing. The wound packing includes a sterile, wound packing of a flexible material capable of absorbing wound exudate, with the flexible material being in the form of a substantially flat, coiled, spirally-cut layer and a package therefor. In certain embodiments of the invention where it is desired that the wound packing remain in place for an extended period, the flexible material is impregnated with a hydrogel, which may be a "wet" hydrogel (i. e. , one containing substantial amounts of water) or a dehydrated hydrogel which is substantially devoid of water but becomes hydrated in use.

Abstract:

A flexible burn dressing product contains a high absorbency hydrogel material in a gel phase. The hydrogel material is formed from a hydrogel composition for use in a wound dressings. The hydrogel composition is formed from a mixture comprising: (a) from about 0% to about 90% by weight polyhydric alcohol selected from the group consisting of polypropylene glycol, polyethylene glycol and glycerine; (b) from about 6% to about 60% by weight aliphatic diisocyanate terminated prepolymer based on polyols containing more than about 40% polyethylene oxide and having an isocyanate content of about 3% by weight; (c) from about 4% to about 40% by weight polyethylene oxide based polyamine; (d) up to about 2% by weight sodium chloride; and (e) the balance water. Such a hydrogel material provides a highly absorbent material capable of retaining large amounts of wound exudate, thereby rendering it very suitable for use in wound dressings.

International Classification:

A61F 1300
A61F 1500

US Classification:

602 42

Abstract:

The present invention provides a wound dressing in the form of a gauze or similar absorbent material having a partially or substantially dehydrated hydrogel material impregnated therein for absorbing wound exudate. The wound dressing is capable of absorbing large amounts of wound exudate without inhibiting the healing of the wound to which it is contacted and without the need for additional backing or adhesive layers. The wound dressing also has a pliable, soft structure which permits the dressing to be applied to wounds having irregular shapes and depths.

International Classification:

A61F 1300

US Classification:

602 57

Abstract:

A flexible, transparent wound dressing product contains a clear hydrogel material in a gel-like phase. The wound dressing product is comprised of several layers including a wound dressing, removable tab and release liner. The removable tab provides a grippable surface to allow for the removal of the release liner from the wound dressing and to facilitate handling of the wound dressing during application to the wound site. The tab may be comprised of a flat, double-coated paper or other suitable material, or a flexible, V-shaped member, and is removable by peeling after the wound dressing is applied. The wound dressing comprises a transparent thin-film layer, a first adhesive layer, backing layer, second adhesive layer, support layer and a hydrogel material. The transparent layer has a center portion and a perimeter portion. The backing layer, support layer and hydrogel material, which together form a reinforced hydrogel patch, are positioned in the center portion of the transparent layer.

Abstract:

A biomedical electrode for an electrocardiograph or similar device is provided. The biomedical electrode includes a disposable electrode having an electrically conductive gel layer and a smooth layer film. The disposable electrode interfaces with a reusable leadwire connector having the relatively expensive metallic conductive material. The reusable leadwire adapter includes a vinyl top layer which attaches to the smooth layer film of the disposable electrode through surface attraction. The reusable leadwire adapter may include a suction cup which attaches to the disposable electrode through a partial vacuum. The reusable leadwire also includes a stud member which snaps into a standard leadwire connector.

Abstract:

A wound dressing for a deep wound is provided. The wound dressing comprises a hydrogel layer having an upper surface and a lower surface. The hydrogel layer is correspondingly sized to fill the cavity of the deep wound. The wound dressing further comprises a dressing removal layer disposed between the upper surface and the lower surface of the hydrogel layer. The dressing removal layer extends outwardly from the hydrogel layer so as to form a pull tab which facilitates removal of the hydrogel layer from the deep wound. A method of making a wound dressing for a deep wound is also provided.
