Embodiment Construction

[0033]In the following description, the term "metal particles" may include an elemental metal particles capable of forming a metal-air electrochemical cell having a metal particles and oxides and a salt thereof. Although other metals and oxides including aluminum, iron, copper or magnesium can be used, zinc metal particles and oxides and salts thereof are preferred.

[0034]Although synthetic fibers are preferred, particularly fibers formed of thermoplastic or thermosetting plastic materials and / or fibers coated with binders, the term "fibers" may include natural and synthetic fibers, filaments and wires.

[0035]Referfigure 1 , According to the self-contained non-battery ionic gel therapy apparatus or device 10 in accordance with the present invention, the patch comprises a flexible substrate 12, a drug carrier, such as a gauze 14, and a sandwich formed by the cover 16 ( Sandwich), the flexible substrate 12 is formed of a sheet-like material such as a gas permeable or irrepermasse text...

Abstract

The present invention provides a device for increasing absorption of substances through the skin of an animal or human, comprising: a fabric or substrate; metal particles disposed on or exposed through at least a portion of a surface of the fabric or substrate, as a plurality of lines or dots in a specific pattern that positions the metal particles in discrete electrically isolated locations separated by a distance, wherein the fabric or substrate is configured such that said metal particles contact a skin surface of the human or animal, wherein the plurality of spaced lines are substantially evenly spaced from one other; and a layer adapted to hold a substance; wherein said fabric or substrate forms a plurality of half-cells of an air-metal battery, for ion exchange with the skin of the human or animal whereupon a substance located between the device and the skin is driven in by iontophoresis.

Description

Technical field[0001]The present invention relates to a method and apparatus for increasing absorption of a substance through a user's skin. The present invention has a particular purpose in increasing the absorption of the drug through the skin, and will be described in conjunction with such use, but other applications, such as increases the speed or depth of the absorption including, for example, a pharmaceutically acceptable material.Background technique[0002]The skin includes epidermis, leather and subcutaneous adipose tissue. When the drug is applied to the skin, the epidermis, the upper layer of the skin, usually, is usually considered foreign matter and hinders the absorption of the drug. As a result, due to the effects of molecular size, biological characteristics, biochemical phenomena, the amount of drugs that actually absorb in the skin is very small.[0003]In order to overcome this problem, ionic electrosurpening has been developed to increase the absorption of drugs thro...
