Thus, a considerably more versatile, cost-effective, durable and efficient syringe guide and vial holder is provided that can accommodate a plurality of syringe and needle sizes as well as various liquid medications and other fluids in vials in the first embodiment as well as in other embodiments with ease of tracking quantities, contents, sizes and locations of a variety of vials, syringes and needles.

A prefilled syringe includes a syringe body filled with a medical fluid, which has a nozzle at a front side, the nozzle being closed with a cap, and which is closed at a rear side with a displaceable plunger; and a plunger rod that can be inserted into the syringe body via the rear side. The plunger rod has a connecting portion at a front side, via whi9ch the plunger rod can be connected to the plunger. At least three annular elements, which extend at least in some sections about a longitudinal axis of the rod, are arranged on a rear side of the connecting portion on the plunger rod in such a manner that they are located in the syringe body when the plunger rod is fully connected to the plunger. The three annular elements support a coaxial connection of the rod to the plunger positioned in the syringe.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a system includes an injection pen device including a dose setting mechanism, a dispensing mechanism, and an electronics unit to generate dose data associated with a dispensing event of a dose of the medicine dispensed from the injection pen device and time data associated with the dispensing event; a mobile device in wireless communication to receive and process the dose data; and a software application configured to determine a recommended dose based on health data and contextual data associated with a user of the injection pen device, the software application including a learning dose calculator module to adaptively calculate the recommended dose of the medicine based on time-relevant and circumstances-relevant data specific to the user of the injection pen device.

A drug delivery device comprising: a housing; a cylindrical member rotatably supported within the housing; and a plurality of sensors; wherein: the outer surface of the cylindrical member is provided with a single track, the track forming an encoder and having a plurality of first track segments and a plurality of second track segments arranged along the length of the track which are respectively capable of inducing first and second responses in the sensors; and in each rotational position of the cylindrical member relative to the housing at least one different first track segment is capable of inducing a first response in at least one said sensor, thereby enabling the rotational position of the cylindrical member relative to the housing to be determined.

A force actuated injection device including a body adapted to contain medication, a grip slidably disposed over the body, a lock disposed between the body and the grip, the lock when locked preventing movement of the grip relative to the body and when unlocked permitting movement of the grip relative to the body, a needle guard retractable relative to the body, a biasing member biasing the needle guard away from the body, and a resistance band disposed between the body and the needle guard adapted to resist initial needle guard retraction relative to the body, wherein force on the needle guard exceeding a predetermined amount overcomes a frictional force of the resistance band allowing the needle guard to retract relative to the body to unlock the grip relative to the body such that movement of the grip relative to the body causes medication to be delivered from the body.

A dosage verification system for use prior to administering an injection of a medicinal fluid drawn into a medical syringe, the system comprising a medical syringe having a barrel with an outwardly facing, flat indicia display surface, plunger having a plunger seal disposed inside and slidably engaging an inwardly facing wall of the barrel and a plunger handle projecting rearwardly from the barrel, and a hypodermic needle projecting forwardly from the barrel, all in combination with an imaging device configured to view and selectively capture, store or transmit a digital image of the plunger position relative to the barrel when a dose of the medicinal fluid is drawn into the fluid chamber of the barrel prior to an injection to verify and provide a record of the dosage drawn, and to alert a user prior to injection when an incorrect dosage is drawn into the fluid chamber of the syringe.

A device configured to administer a medication can comprise a lower housing that includes a housing latch. The device can further comprise a needle guard that is movable relative to the lower housing along a first direction from a first position to a second position so as to expose a needle, and an upper housing supported relative to the lower housing. The upper housing can be configured to move with respect to the lower housing along a second direction from a pre-use position to a dispensed position. The housing latch can releasably interfere with the upper housing when the upper housing is in the pre-use position so as to prevent the upper housing from moving toward the dispensed position, and the movement of the needle guard toward the second position, causes the interference to be removed, thereby allowing the upper housing to move toward the second position.

Provided is an injection device, comprising a syringe comprising a needle, a barrel, a stopper in sliding engagement inside the barrel, a plunger unit moveable with regard to the barrel, a case accommodating the barrel and provided with elastic means and an operating stop, and a needle shield adapted to be moveable under the force of the elastic means from an injection position to a safety position, and provided with a shield stop, wherein the operating stop is configured to prevent the needle shield to move to the safety position by abutting against the shield stop, wherein the plunger unit comprises a triggering portion configured to deflect the flexible leg of the needle shield when the plunger unit has reached a triggering position during its injection movement.
