SKIN-ATTACHABLE MINIATURE DRUG INJECTION DEVICE WITH REMOTE ACTIVATION CAPABILITY AND DRY DRUG CARRIER WITHIN INJECTION NEEDLE
First Claim
1. An active agent injecting device for injecting an active agent into a living organism, the injecting device including:
- (a) a main housing;
(b) an energy storage device located inside the main housing, the energy storage device biasing an activation mechanism;
(c) an injection assembly having a needle enclosing a carrier comprising an active agent; and
(d) a trigger mechanism which triggers the injection assembly to release the needle to inject the active agent into the living organism.

Abstract
An active agent or drug injecting device (10) includes a main housing (16) containing a trigger mechanism (24) which can be manually activated via release bar (32) or remotely triggered via wireless receiver (70) activating motor (74), and a second housing (80) containing an injection- and needle-assembly (22). The needle (30) encloses a dry carrier (26) having an active agent (12) disposed thereon. The trigger mechanism triggers the injection assembly to propel the needle into the skin (via spring (54)), to inject the active agent into a living organism (either by letting the active agent diffuse out of the needle or by actively flushing it out), and to subsequently retract the needle back into the housing (80) (via spring (64)).
