A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.

The present disclosure relates unlocking operation of an injection device. The injection device includes a housing configured to accommodate a medicament container and a drive mechanism operably engageable with the medicament container for expelling or withdrawing the dose of the medicament, where the drive mechanism includes at least one interlock configured to disable at least one of setting of the dose and dispensing of the dose. The injection device further includes an identifier provided on or associated with the medicament container and an electronic unit operably engaged with the at least one interlock, the electronic unit including a short-range communication interface to communicate with a corresponding short range communication interface of an external electronic device to obtain information indicative of the identifier. The electronic unit is configured to process signals of the short-range communication interface to at least temporally deactivate the at least one interlock.

A pump for use in low-profile applications comprises a barrel for holding fluid; and a piston that converts a rotational driving force into a longitudinal driving motion within the barrel. The pump provides space saving advantages by reducing the need for external equipment and mechanisms around the pump for providing actuation or moving the actuating mechanism.

An infusion device includes a housing with an interior chamber sized and configured to hold at least a flange and plunger of a syringe, a trigger held by the housing, and a lever in communication with the trigger and including an upwardly extending cam with a cam path having an upper end. The cam is in communication with the flange of the syringe. In response to actuation of the trigger to dispense fluid from the syringe, the upper end of the cam travels upward above the syringe and longitudinally toward a dispensing end of the syringe to linearly translate the plunger of the syringe in a first direction to dispense fluid from the syringe. To refill fluid into the syringe, the upper end of the cam travels downward and longitudinally away from the dispensing end of the syringe to linearly translate the plunger in a second direction to intake fluid.

A dispensing mechanism for delivering a dosage of medicament including a housing, a push button, a crank arm that is slideably engageable with the push button, a ram, and a ratchet gear releasably engageable with the crank arm and ram, translation of the push button along an axis causing the crank arm to engage and rotate the ratchet gear which causes the ram to distally advance relative to the housing.
