Abstract
An Advanced Electrolytic Device-Bimetallic Wound Dressing that provides galvanic current and has antimicrobial properties. The dressing comprises a pliable base material, along with a pattern of deposited metal powder and flakes. The metal powder and flakes include at least two different metal types. The two different metals create a galvanic current in the wound area.
Claims8
A wound dressing, comprising a base material;
- a surface suitable for contacting a wound, and a pattern of deposited medical grade metal powder and flakes on said surface wherein at least two types of metals are present, comprising a first metal having an electrochemical potential and a second metal having a different electrochemical potential from said first metal, said metals being deposited and adhered to said surface in a non-conductive water soluble carrier/binder to create metal formulations deposited in a non-touching pattern, further wherein said dressing comprises a pliable base material and said metal formulations comprise at least two metals which, upon nearly touching, generate an efficient and sustainable galvanic current and wherein said layout is such that the ratio of metallic formulations is as close to one-to-one silver to zinc as possible by screening 2 mm and 1 mm circles in an equal layout such that each silver dot is surrounded by at least 4 half dots of zinc to achieve the desired ratio of metals, and all dots are applied to the same side of said fabric with spacing between said metal formulations' being approximately 1 mm in alternating rows.
