Abstract: An auto-injector for hypodermic delivery of medication includes a first subassembly releasably coupled to a second subassembly. The first subassembly includes a cartridge holder configured to receive a medication cartridge, an injection needle through which medication can pass from the medication cartridge, and a needle shield movable between an extended position enclosing the needle and a retracted position in which a proximal end of the needle is not enclosed by the needle shield. The second subassembly includes a movable plunger rod positioned within a housing. Movement of the needle shield in a proximal direction from the retracted position to the extended position following administration of the medication automatically releases the first subassembly from the second subassembly. The released first subassembly is locked with the needle shield in the extended position. A new first subassembly containing an unused dosage of medication may be inserted and releasably connected to the second subassembly.

Abstract: The present invention relates to a medicament delivery device comprising a housing, which housing is arranged to accommodate a medicament container, which medicament container comprises a medicament delivery member; a power unit interactively connected to the housing comprises a force element and a plunger rod which is arranged to, upon activation, move linearly in the proximal direction and act on said medicament container for expelling a dose of medicament through said medicament delivery member; and a holding member connected to said power unit and to said container holder. The invention is characterized in that the plunger rod comprises at least one first guide-and-stop element configured to interact with at least one second guide-and-stop element on said a holding member for limiting the linear distance the plunger rod is capable of moving during expelling of medicament and which distance corresponds to a dose volume.

Abstract: A limiter for a dispensing device is provided. The limiter includes a body (20) arranged to mount with at least a portion of a dispensing device (300), and a stop extending from the body. The stop (40) is configured to permit movement a plunger of the dispensing device a predetermined distance in a dispensing direction correlated to a desired volume of medium to be delivered from the dispensing device. The stop is configured to prevent further movement of the plunger in the dispensing direction, thereby limiting the amount of medium delivered from the dispensing device. The dispensing device may be a syringe.
