摘要:
An auto injector having sequential control of needle insertion and dose injection is disclosed. A syringe with a needle is movably positioned in a housing between a first position in which the needle is accommodated inside the housing and a second position in which the needle protrudes outside the housing. A plunger rod tube has at least one locking member configured to normally lock a plunger rod to the plunger rod tube. A syringe driver applies a force to the syringe to move the syringe together with plunger rod tube, plunger rod and plunger rod driver from the first position to the second position. In the second position, the locking member is unlocked and releases the plunger rod to thereby activate the plunger rod driver to advance the plunger rod in the syringe for delivering of at least one dose of medicament.
