Implementations of the present disclosure are directed to an injection device (102) including a medicament reservoir (103) configured to store a medicament to be expelled by the injection device (102), an acoustic source (122a, 122b, 122c, 122d, 200, 300, 400) configured to generate an acoustic signal including information indicative of an amount of the medicament stored in the medicament reservoir (103), the acoustic signal being transmitted to an external device (104) configured to process the acoustic signal and to extract injection device data.

An automatic medication injection device that provides a user with audible notice of injecting progress. The device in one form includes a plurality of sound elements located on drive mechanism portion that inserts within a barrel of a container of medication to advance a sealing plunger of that container. The device also includes at least one actuating element movable axially with the container of medication within the device housing, which at least one actuating is element arranged to engage the plurality of sound elements to generate audible notices as the advancing portion moves past the at least one actuating element when advancing the sealing plunger for an injection.

An injection system includes a handle assembly with a handle body having an outer surface surrounding a handle body interior and a plunger extending therethrough. A tubular handle collar is telescopically received in the handle body exterior and is axially movable with respect to the handle body. A syringe housing assembly is selectively connectable to the handle assembly and includes a syringe housing and a tubular syringe sleeve telescopically received through a distal end of the syringe housing and axially movable with respect thereto. The syringe housing has an exterior side surface surrounding a syringe housing interior configured to receive at least a portion of a syringe. The syringe sleeve has a proximal end, a distal end with a skin contact surface, and a generally cylindrically-shaped outer surface.

The disclosure relates to a syringe support for supporting an axial position of a syringe relative to a housing of an autoinjector. The syringe support comprises a projecting portion, which projects from the syringe support in a distal direction and a flexible portion which axially adjoins the projecting portion. The flexible portion is adapted to axially bias the syringe in the distal direction within the housing. The disclosure further relates to an autoinjector.

Drug delivery systems, devices and methods of use for recording a drug dose completion signal in a data management system are provided. Aspects of the invention include drug delivery systems comprising a syringe stopper rod that comprises a sensor component comprising a wireless transmitter module and an activation component configured to activate the sensor component when the syringe stopper rod has completed a delivery stroke, wherein the wireless transmitter module is configured to transmit a report comprising a drug dose completion signal when the sensor component is activated.

The present disclosure is generally directed to a drive mechanism for use in a drug delivery device having a cylindrical cartridge, i.e. a handheld injection device for selecting and dispensing a number of user variable doses of a medicament. The drive mechanism includes a base element, a toothed piston rod, which is guided within and movable relative to the base portion, and a drive gear having a pinion, which is rotatably held in the base element and in meshed engagement with the toothed piston rod. The toothed piston rod includes multiple rigid rod pieces which are connected by hinges. The rigid rod pieces comprise a flat plate provided with a straight toothed rack.

A medication injection pen (50) includes a housing (1) and a dose set knob (2) rotatably connected to the housing (1) for setting a dose. An indicator member (200) is movable between a visible position indicating a zero position of the dose set knob (2) and a non-visible position indicating a non-zero position of the dose set knob (2). The indicator member is visible to a user in the visible position and not visible to the user in the non-visible position. The dose set knob is in the zero position when a set dose has been completely administered. Accordingly, a visible indication is provided to the user when a set dose has been completely administered.

The present invention relates to a torsion spring based automatic injection device for apportioning set doses of a liquid drug and which injection device is provided with an End-of-Dose feedback mechanism providing a user with an audible signal once the set dose has been injected. During injection, the scale drum rotates back to its “zero” position under influence of the torsion spring. This rotation is halted shortly before reaching the “zero” position by stopping means. The scale drum is thereafter only allowed to continue rotation and thus reach the “zero” position once the torque applied to the scale drum by the torsion spring surpasses a threshold value.

An injector device includes an injector body that receives a syringe; and an injection assembly being configured to dispense medicament from the syringe in a dispensation step. Certain types of injector devices include a sudden completion indicator that indicates when the injection is completed. Certain types of injector devices are configured to dispense two different medicament formulations having different viscosities from syringes without making any changes to the injector devices other than to switch out the syringes. Certain types of injector devices include safety arrangements that inhibit firing of the injector device until front and rear housing assemblies are disposed in predetermined rotational and axial positions relative to each other.
