Abstract
A multilayer laminate wound dressing comprising a plurality of layers of preferably silver or silver-coated fibers in a woven fabric alternating with layers of nonconductive, preferably nonmetallic, fabric. Each layer preferably contains a different ratio of metalized to nonmetalized fibers. The metalized fibers are preferably made of or coated with silver. The dressing promotes healing by stimulating cellular de-differetiation, followed by cellular proliferation. The dressing also has antibacterial, antifungal and analgesic properties.
Claims24
A wound dressing, comprising a plurality of layers of a fibrous material, said material containing nonmetalized fibers and fibers that are at least partially coated with a metallic material to yield metalized fibers, each layer being joined to an adjacent layer and having a ratio of metalized fibers to nonmetalized fibers, wherein said layers form a gradient of metalized fiber to nonmetalized fiber ratios, the highest ratio layer capable of being placed in a contact with a wound site.
A wound dressing capable of being applied to a wound site, comprising:
- a) a first layer of a semipermeable fibrous material comprising a first ratio of metalized to nonmetalized fibers;
- b) a second layer of a semipermeable fibrous material comprising a second ratio of metalized to nonmetalized fibers;
- c) a third layer of a semipermeable fibrous material comprising a third ratio of metalized to nonmetalized fibers;
- wherein said first ratio layer is laminated to said second ratio layer and said second ratio layer is laminated to said third ratio layer so as to form a gradient of metalized to nonmetalized ratio layers, the highest ratio layer being capable of being in contact with a wound site, such that metal ion from said metalized fibers are capable of migrating towards and contact said wound site.
A wound dressing, comprising:
- a plurality of laminated layers of a fibrous material, said material containing metalized fibers, each layer having a unique ratio of metalized fibers to nonmetalized fibers, a plurality of separating layers of a nonconductive porous material disposed between said layers of fibrous material, wherein said layers form a gradient of metalized fiber to nonmetalized fiber ratios, the highest ratio layer capable of being placed in contact with a wound site.
An antibacterial treatment for a dermal layer site, comprising:
- a plurality of laminated layers of a fibrous material, said material containing metalized fibers, each layer having a unique ratio of metalized fibers to nonmetalized fibers, a plurality of separating layers of a nonconductive porous material disposed between said layers of fibrous material, wherein said layers form a gradient of metalized fiber to nonmetalized fiber ratios, the highest ratio layer capable of being placed in contact with a wound site.
A method of treating a wound to promote healing, comprising:
- a) providing a wound dressing comprising a plurality of laminated layers of a fibrous material, said material containing metalized fibers, each layer having a unique ratio of metalized fibers to nonmetalized fibers, a plurality of separating layers of a nonconductive porous material disposed between said layers of fibrous material, wherein said layers form a gradient of metalized fiber to nonmetalized fiber ratios, the highest ratio layer capable of being placed in contact with a wound site;
- and,
- b) applying said dressing to a wound so that silver ions are capable of migrating to said wound and contact cells proximate to said wound.
A method of alleviating pain associated with a wound, comprising:
- a) providing a wound dressing comprising a plurality of laminated layers of a fibrous material, said material containing metalized fibers, each layer having a unique ratio of metalized fibers to nonmetalized fibers, a plurality of separating layers of a nonconductive porous material disposed between said layers of fibrous material, wherein said layers form a gradient of metalized fiber to nonmetalized fiber ratios, the highest ratio layer capable of being placed in contact with a wound site;
- and,
- b) applying said dressing to a wound so that silver ions are capable of migrating to said wound and contact cells proximate to said wound.
A wound dressing, comprising:
- a) at least one first layer of essentially silver fibers;
- and,
- b) at least one second layer of nonconductive fibers;
- said at least one first layer being laminated to said at least one second layer.
