Abstract
Abstract A transdermal drug applicator (100) for application to a living body for the delivery of at least one drug through the skin (144) into the bloodstream comprising an applicator (100) including at least one drug reservoir (182A,182B) containing the drug for delivering same through the skin (144) by physico/chemical mass transfer. A mounting structure (138, 140) is removably mounted to the body for holding the applicator (100) to the skin (144), with the applicator (100) removably connected to the mounting structure (138,140). A power supply (166) for the applicator (100) and a circuit transmitting electrical power from the power supply (166) to the applicator (100) is disclosed, wherein an electric circuit is created between the applicator (100) and the skin (144). The device includes a computer (158) with the mounting structure (138,140) for receiving programmed instructions relative to the drug, and transmitting signals relative to the drug and the programmed instructions to the power supply (166) for regulating the generation of power and delivery of drug through the skin (144).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
237 words
A two-part replenishable drug applicator system for transdermal drug delivery of at least one drug to the systemic blood of a human being or animal through skin thereof comprising: a reusable assembly having a computer control part of said drug applicator system removably mountable on said human or animal for control of transdermal delivery of at least one drug through the skin; said computer control part including a source of electrical energy for electrically energizing said drug applicator system and effecting flow of current through the skin; a drug containing cartridge comprising a replaceable drug reservoir for containing at least one drug and replaceably mountable on said computer control part in a separable assembly for replenishing said drug applicator system with at least one drug as required; said drug reservoir having a permeable surface for contacting the skin of said human being or animal when said drug reservoir is mounted on said computer control part; and means on said drug reservoir and means on said computer control part for cooperative association when said drug reservoir is mounted on said computer control part effectively establishing a current flow path from said computer control part to said drug reservoir and through the skin of said human being or animal for application of controlled electrical current to said drug reservoir for application of a drug through said surface thereof in contact with the skin of staid human being or animal.
Claim 2
Dependent Claim
237 words
A two-part replenishable drug applicator system for transdermal drug delivery of at least one drug to the systemic blood of a human being or animal through skin thereof comprising: a reusable assembly having a computer control part of said drug applicator system removably mountable on said human or animal for control of transdermal delivery of at least one drug through the skin; said computer control part including a source of electrical energy for electrically energizing said drug applicator system and effecting flow of current through the skin; a drug containing cartridge comprising a replaceable drug reservoir for containing at least one drug and replaceably mountable on said computer control part in a separable assembly for replenishing said drug applicator system with at least one drug as required; said drug reservoir having a permeable surface for contacting the skin of said human being or animal when said drug reservoir is mounted on said computer control part; and means on said drug reservoir and means on said computer control part for cooperative association when said drug reservoir is mounted on said computer control part effectively establishing a current flow path from said computer control part to said drug reservoir and through the skin of said human being or animal for application of controlled electrical current to said drug reservoir for application of a drug through said surface thereof in contact with the skin of staid human being or animal.
