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: 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. The piston is configured to translate a plunger seal and a barrel. A tether is connected between the piston and the winch drum to restrain the free expansion of the biasing member and the free axial translation of the piston upon which the biasing member bears upon. The drive mechanism may further include a gear assembly having a motor configured to drive the gear assembly to release the tether from the winch drum. The metering of the tether by the motor controls the rate or profile of drug delivery to a user. A drug delivery pump includes such a controlled delivery drive mechanism. A control system may be utilized to control the desired drug delivery rate/profile.

The housing may further include a cartridge cover. A drive control mechanism includes a drive screw, a cartridge carrier, a plunger carrier, and one or more control transfer instruments, such as a puck or cylinder. The drive screw interfaces and connects with the plunger carrier. The automatic injector is configured to accept a variety of syringes as cartridges for drug delivery. The cartridges may be ejected from the injector and safely disposed after use, making the injector a reusable automatic injector. The reusable automatic injector may further include one or more sensors, such as a cartridge sensor and a patient sensor.

Abstract: A drive mechanism having integrated status indication includes a drive housing, a status switch interconnect, a drive biasing member, a piston, and a drug container having a cap, a pierceable seal, a barrel, and a plunger seal, wherein the drive biasing member is configured to bear upon an interface surface of the piston. Drive mechanism may include an incremental status stem having a stem interconnect, wherein the stem resides within the drive housing and the piston, and wherein the stem has an interconnect which engages one or more contacts on the piston to provide incremental feedback. A drug delivery pump with integrated status indication includes a housing and an assembly platform, upon which an activation mechanism, an insertion mechanism, a fluid pathway connection, a power and control system, and the drive mechanism having a drug container may be mounted.

Abstract: The fluid infusion system is disclosed that includes a pump housing that has a reservoir cavity and is designed to be pocketable. The reservoir cavity has a rim and helical coupling features formed on an interior face of the reservoir cavity. The fluid infusion system further has a reservoir that is removable from the reservoir cavity and the reservoir also has an open end. A removable cap coupled to the pump housing is also included in the fluid infusion system. The cap has corresponding coupling features, an exterior surface and a tab. The corresponding coupling features are defined to couple the cap to the pump housing while the tab is defined as a ridge that extends away from the exterior surface. The tab further has a port to accommodate fluid flow from the reservoir where the port defines and axis of rotation such that torque applied to the tab about the axis of rotation disengages the coupling between the cap and the pump housing.
