Abstract: A drive mechanism includes a housing, a piston adapted to impart movement to a plunger seal within a drug container, a plurality of biasing members disposed in parallel, and a retainer. The biasing members are disposed to release energy to cause movement of the piston from a retracted first position to the extended second position, the piston bearing against the plunger seal to dispense medicine. The retainer is disposed to maintain the biasing members in the energized position and to release the biasing members to permit the piston to dispense the medicine. The drive mechanism may also include an end-of-dose indicator to identify at least one of when the sleeve assembly is disposed subjacent a window in the housing, the relative motion of the sleeve assembly with reference to the window or another reference component, the stoppage of such motion, and the rated or change of rate of motion.

Abstract: A controlled delivery drive mechanism includes a drug container having a barrel and a plunger seal; a drive housing within which at least initially partially resides a piston having an interface surface and a drive rack; and a power spring. The piston is configured to contact and axially translate the plunger seal within barrel. The mechanism may be configured to convert rotational movement of a drive pinion to axial translation of the drive rack, or to convert axial force of a linear power spring into torsional motion of a drive pinion. A regulating mechanism meters the drive pinion such that the piston is axially translated at a controlled rate. The drug container may contain a drug fluid within a drug chamber for drug delivery at a controlled rate. The regulating mechanism may be an escapement regulating mechanism. A drug delivery pump includes such controlled delivery drive mechanisms.

Abstract: Handheld drug delivery devices for injection of a medicament into a target location are disclosed herein. The drug delivery devices of the present disclosure include drive mechanisms, needle insertion mechanisms, and fluid pathway connectors. These components may be arranged within a housing. The arrangement of these components may provide an easy to use device that is capable of delivering volumes larger than traditionally injected using syringes. Translation of a drug container of the device may cause connection of a fluid pathway from the drug container for delivery of a medicament to a target location.

Abstract: A controlled delivery drive mechanism includes a drive housing, a piston, and a biasing member initially retained in an energized state and is configured to bear upon an interface surface of the piston.

A drug delivery pump utilizes such variable rate controlled delivery mechanisms. A status reader configured to recognize one or more corresponding status triggers is utilized to provide feedback to a user.
