| 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 )). |
