摘要：
A pharmaceutical delivery apparatus with an automatic syringe retraction following a manually controlled injection. The apparatus includes a housing (28), a syringe carriage (90), a medication-filled syringe (70) held within the carriage, the syringe needle tip being disposed within the housing in a first position and projecting from the housing beyond the housing proximal end for insertion into an injection site in a second position, a manually shif table plunger (130), means on the carriage and the housing and the plunger for causing the carriage to advance from the first position to the second position and for injecting medicine from the syringe when the plunger is manually plunged proximally toward the housing, and means on the carriage and the plunger for causing the carriage to retract from the second position to a position at which the needle tip is disposed within the housing when the plunger shifts distally.
