Abstract
An automatic accurate dose syringe includes a barrel, a plunger seal, a barrel adapter assembly having a barrel tip and a needle, and a dose control mechanism having a plunger having a coarse pitch screw on its exterior surface, a housing having a corresponding coarse pitch guide along the interior surface of the housing, a screw having a fine pitch screw which interfaces with a fine pitch nut of an adapter, wherein the plunger has an internal annular space within which screw at least partially resides. The syringe further includes a locking mechanism, an activation button, and a biasing member such as a compression and/or a torsional spring. The components are configured such that actuation of the activation button by the user manipulates the locking mechanism to permit the biasing member to move from an initial energized state to a lower energy state, thereby automating drug delivery from the syringe.
