An injector apparatus includes a housing (10.sup.1, 10.sup.2) for a cartridge or syringe, a plunger (40) for cooperating in use with the cartridge or syringe to express successive doses, a dose setting arrangement (16, 20) to select a dose volume, and a drive mechanism (22, 24) releasable to advance the plunger in respective predetermined increments of magnitude to express the successive doses. The drive mechanism includes a drive spring (22) for imparting movement directly or indirectly to the plunger (40), and the dose setting arrangement includes a dose setting element (16) moveable in a dose setting routine to define a magnitude of an increment of movement of the plunger for a given dose. The drive mechanism further includes a clutch arrangement (56) operable during the dose setting routine to inhibit forward movement of the plunger and/or to isolate the dose setting element from the force of the drive spring.

A medical device and system for the administration of a medical substance or for dosing body fluids comprising a rotor, rotating around an axis X-X, operatively connected to an injection device of said medical substance, and a rotor locking/unlocking device mechanically separate from the rotor and integral in rotation therewith. The locking/unlocking device comprises, in one piece, a disc, centered with respect to said axis X-X, from which a plurality of flexible fins radially unravel. The flexible fins are configured to flex around transverse hinges at a connection portion with the disc, and are angularly spaced so as to define gaps between adjacent pairs of fins which prevent interferences between adjacent fins in the respective flexing movement. The flexible fins are associated with ferromagnetic means for the operation of the same fins and locking/unlocking means of the rotation of the disc. The disc and fins are formed from a single plastic body.

A syringe includes a dosage setter operatively coupled to a plunger rod and comprising a rotatable body that comprises a set of one or more stops for engaging the set of one or more protrusions of the plunger rod depending on at least a rotational position of the set of one or more stops relative to the set of one or more protrusions, wherein a first rotational adjustment associated with the dosage setter is configured to set a first dosage increment by adjusting a relative axial position between the rotatable body and the plunger rod, and a second rotational adjustment associated with the dosage setting assembly is configured to set a second dosage increment that is larger than the first dosage increment by adjusting a relative rotational alignment between the set of one or more stops and the set of one or more protrusions.

A syringe having a mechanical ejection mechanism. The ejection mechanism includes an actuator and a rotational gear. The actuator has a retractable pawl configured to engage the gear when the actuator is displaced from a non-depressed position into a depressed position. Displacement of the actuator causes the gear to rotate by a predetermined angle. The rotation of the gear is translated into linear displacement of the plunger within the barrel, thereby ejecting a predetermined amount of solution from the barrel.

A mini syringe includes a tubular base member, a microneedle unit including a microneedle device and a compressible pharmacy housing device and mounted in the bottom side of the base member, a plunger mounted in the base member and pressable to compress the pharmacy housing device, and an adjustment cover threaded onto the base member for controlling the moving distance of the plunger in a micro-adjustable manner.

Sensing systems are disclosed for determining the relative rotational movements of members of a medication delivery device which are proportional to the amount of a dose set and delivered by the medication delivery device. The sensing system comprises a first sensor component secured to a first member and a second sensor component secured to a second member. During dose setting, the second member is coupled to a third member which rotates relative to the first member in proportion to the dose set. During dose delivery, the second member is coupled to a fourth member which rotates relative to the first member in proportion to the dose delivered. The sensing system separately detects the relative rotational positions of the first and second sensor components during dose setting and dose delivery, and provides outputs used to determine the amounts of the set and delivered doses. The sensing system outputs this information to a controller which determines the amount of the dose set and delivered. Related medication delivery devices and methods are also disclosed.
