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)).
