Various embodiments of a device, a kit and method for delivering a drug depot are disclosed. The device comprises a housing including a lower body, an upper body, a ring member; and a drug cartridge. The lower body defines a lower body channel. The upper body defines an upper body channel. The drug cartridge defines a depot channel. The ring member is disposed extending upward from an annular step surface of the lower body toward a housing upper end. The ring member includes indicia indicating a characteristic of one or more drug depots in the drug cartridge. A plunger has a push rod for expelling the drug depot through the cannula to a site in the patient. A kit comprises the above components. A method includes assembling the components including selecting a ring member having indicia corresponding to one or more drug depots in the drug cartridge.

An injection device, method, and system for drug delivery includes a container for storing a drug, the container having a stopper movably disposed in the container for expelling the drug; an injection drive mechanism having a plunger for acting on the stopper and an energy source having a first selected potential energy for exerting a force on the plunger to cause the plunger to act on the stopper to expel the drug; and a plunger loading mechanism for substantially preventing the plunger from accelerating to a predetermined velocity before it acts on the stopper. The plunger loading mechanism may be a spring having a second selected potential energy for reducing or eliminating a distance between the plunger and the stopper, prior to the plunger accelerating to the velocity. The second selected potential energy of the spring may be less than the first selected potential energy of the energy source.

The pharmaceutical injection device includes a pharmaceutical syringe mounting portion (3) provided within a main body case (2) and to which a pharmaceutical syringe (4) is removably mounted, a piston (5) provided movably with respect to the pharmaceutical syringe (4) mounted to the pharmaceutical syringe mounting portion (3), a drive mechanism (6) for driving the piston (5), a controller (7) that is electrically connected to the drive mechanism (6), a display section (35) that is connected to the controller (7), and an encoder (26) that is connected to the controller (7) and detects the amount of the pharmaceutical remaining inside the pharmaceutical syringe (4). The controller (7) displays a warning on the display section (35) recommending removal of the pharmaceutical syringe (4) from the pharmaceutical syringe mounting portion (3) when the presence of a pharmaceutical is detected by the encoder (26).

Provided is a housing part for an auto-injector comprising a shell form body defining inner and outer shell surfaces and comprising a relatively hard or generally incompressible material; an over-coating formed of a relatively softer or more compressible material, the over-coating covering at least part of the outer shell surface of the shell form body; and at least one window defined in the shell form body, wherein the over-coating extends into the at least one window. Also provided is a housing comprising the housing part, and an auto-injector comprising the housing.

An automatic injection device has an insertion needle configured to be inserted into a patient and a drug container which contains a pharmaceutical product. The drug container includes a plunger. The automatic injection device also has a fluid path which fluidly connects the drug container to the insertion needle. The automatic injection device further has a drive system configured to cause linear movement of the plunger to force the pharmaceutical product into the fluid path. The drive system has a driving element and a movable element. The automatic injection device additionally has electronics configured to provide a signal to the drive system to move the plunger. The movable element has an outer magnet at least partially surrounding the drug container and an inner magnet inside the drug container.

An injection device for the delivery of medicament is disclosed having an indicator for providing an activation indication. The device includes a housing; a plunger slidably mounted within the housing; an actuation mechanism configured, in use, to move the plunger forward relative to a syringe so as to express medicament from the syringe. The device also includes an indicator element responsive to the forward movement of the plunger and configured to provide an audible and/or tactile and/or visual indication when the plunger reaches or approaches its forward position. The plunger includes an elongate shaft formed of at least two telescopic sections. The actuation mechanism acts on the plunger, in use, to expand the telescopic sections and to sequentially move each of the telescopic sections forwardly within the housing. The indicator element is arranged to be responsive to the forward movement of the trailing telescopic section.

A resettable and reusable auto-injector with a trigger having a pivot axis dividing an elongate body into distal and proximal portions. The proximal portion has a finger surface on an upper section and a bearing surface projecting downwardly configured to engage a button blocker to function as a safety feature to prevent premature firing of the auto-injector before a needle hider is pressed against an injection site.

A pharmaceutical cartridge holding unit holds a pharmaceutical cartridge and is mounted to a pharmaceutical injection device main body in order to mount the pharmaceutical cartridge to a pharmaceutical injection device. The pharmaceutical cartridge holding unit comprises an outer peripheral cap having a distal end opening and a rear end opening, and a cartridge cover that is disposed on the inside of the outer peripheral cap and is held in a state of being able to slide forward and backward with respect to the outer peripheral cap. The outer peripheral cap has a guide component that guides the sliding of the cartridge cover forward and backward, stoppers that prevent the cartridge cover from coming loose from the outer peripheral cap, and protrusions that can engage with the pharmaceutical injection device main body.

Disclosed is an auto injector and a method for administering a medicament. The auto injector comprising: a housing; a cartridge receiver; a drive module coupled to move a plunger rod configured to move a first stopper; a temperature sensor configured to provide a temperature signal indicative of the temperature of the medicament in the cartridge; a processing unit configured to: receive the temperature signal; control the drive module to move the plunger rod from a first plunger rod position to a mix plunger rod position wherein the movement from the first plunger rod position to the mix plunger rod position is based on the temperature signal.

A medication delivery device and/or dosing mechanisms suitable for use in medication delivery devices, in particular in pen-type injectors, preferably having a dose setting system and a drive device enabling the administration of a medicinal product from a single- or multi-dose medication cartridge.
