Electronic transdermal drug delivery system
First Claim
1. An assembly for the transdermal administration of a drug to a patient, comprising:
- a base unit having a timer and electrical connections for issuing electronic timing information from said timer;
a drug administration unit electrically connected to said base unit, said drug administration unit having a housing defining a space therein for receiving a drug and said housing having drug dispensing conduit means formed therein, a skin-contacting surface to be placed on a patient'"'"'s skin, dispensing means for selectively causing time-dependent dispensing of a drug from said space in said housing through said conduit means to said skin-contacting surface and to the patient'"'"'s skin, and means for generating pressure waves at said skin contacting surface for facilitating transdermal absorption of the drug dispensed to said skin contacting surface.

Abstract
A drug delivery system for transdermally delivering drugs through a given skin area is provided. The delivery system comprises a collapsible container for containing the drug. The container has a drug release opening. A displaceable member is in engagement with the container for expelling the drug from the container via the release opening. A driver is connected with said displaceable member so as to drive the same towards the collapsible container. Conduits are disposed between the release opening and the skin area for conducting the drug to the skin area. An ultrasonic transducer is disposed in the general conduit area for generating ultrasonic waves aimed at the skin area. An ultrasonic waveform generator drives the transducer and an electric control circuit is connected to the flow control for electrically activating the flow control.
