Drug delivery device and method
First Claim
1. A drug delivery device for delivering a predetermined drug dose to a body region of an individual, the drug delivery device comprising:
- (a) a reservoir being for containing a liquid preparation of a drug;
(b) a drug delivery element being for delivery of said liquid preparation into the body region;
(c) a drug delivery mechanism being capable of fluid communication with one of said reservoir and said drug delivery element at a given time, such that when activated, said drug delivery mechanism cycles through a mode of acquisition of a quantity of said liquid preparation from said reservoir and a subsequent mode of expulsion of said quantity of said liquid preparation acquired from said reservoir, through said drug delivery element into the body region, wherein the predetermined drug dose is delivered by a predetermined number of said cycles.
