Painless drug implanter

Abstract

The present invention relates to a drug implant device which delivers a drug load to the body painlessly. The present invention achieves the painless drug implantation by adopting two principles: (1) rapid perpendicular insertion of fine cannula is painless and that (2) pain is incurred only when the occupied volume caused by the implant process is increased. Therefore, instead of inserting a cannula and injection a volume of drug, which increases the occupied volume of the injection process due to additional volume of the drug, the present invention retracts the cannula in order to dispose the drug into the body. The retraction of cannula does not increase the occupied volume therefore incurs no pain. In the preferred embodiment, the drug implant device (100) comprises a cannula (300) with a bevelled tip, a drug load (320) and an inner rod (340), wherein the drug load (320) and the inner rod (340) are slidably disposed within the cannula (300), and that the drug load (320) is disposed at the bevelled end of the cannula (300) and that the inner rod (340) is disposed adjacent to the drug load (320).
