Exemplary embodiments provide automatic injection devices, housing components for automatic injection devices and methods for fabricating the same. An exemplary housing of an automatic injection device may be overmolded with one or more gripping surfaces to facilitate gripping and manipulation of the automatic injection device by a user when performing an injection. In an exemplary embodiment, an overmolded left gripping surface may extend along a left side of the housing and an overmolded right gripping surface may extend along a right side of the housing opposite to the left side.

An assembly for a drug delivery device is provided, the assembly comprising a feedback feature. The feedback feature is configured to indicate an end of the dispense operation to a user by giving an audible and/or tactile feedback.

The present specification relates to a drug delivery device including a housing adapted to receive a primary container with a piston, a plunger slidably disposed in the housing and adapted to drive the piston for delivering a medicament, a drive spring pre-loaded between the housing and the plunger so as to urge the plunger in a distal direction, an audible and/or tactile indicator, and a trigger mechanism arranged between the indicator and the plunger. The trigger mechanism is configured to support the indicator in an initial state of the device and during delivery of the medicament and to couple with the plunger to activate the audible and/or tactile indicator at or near an end of delivery.

A container for an injectable medicament is provided. The container can include an elongated body having a tubular-shaped sidewall extending along a longitudinal axis and having a distal end and a proximal end. The container can include an outlet at the distal end and a bung arranged inside the elongated body, sealingly engaged with the sidewall and slidable along the longitudinal axis relative to the sidewall. The container can include an interior volume to receive the injectable medicament and being confined by the sidewall, the outlet, and the bung. The container can include a measuring arrangement arranged in or on the bung. The measuring arrangement can include a signal generator configured to emit a measurement signal into or through the interior volume, the measurement signal being capable to stimulate or to excite a resonance of the container. The measuring arrangement can include a signal detector configured to detect a feedback signal indicative of a resonating interaction of the measurement signal with at least one of the sidewall, the outlet or the interior volume.

A medicament delivery system, including a medicament container and a delay mechanism that is activated prior to completion of medicament delivery from the medicament container. The delay mechanism automatically activates a subsystem or initiates an operation subsequent to completion of medicament delivery.

The present disclosure refers to a switch assembly for an electronic system of a drug delivery device. The switch assembly comprises a chassis supporting a PCBA which has a distal surface comprising at least a first electrical contact, a second electrical contact and a third electrical contact, and a ring. The chassis moves axially relative to the ring from a first axial position to a second axial position during a first switch operation mode. The chassis and the ring are configured such that the ring rotates relative to the chassis during a second switch operation mode. The ring comprises an annular continuous first electrically conductive area and an annular segmented second electrically conductive area which is connected to the first area.

An incremental syringe useful for multiple injections of medications like botulinum toxin is provided. The syringe includes detents on the syringe plunger which provide a tactile feeling, a discrete audible sound or “click,” or preferably both, for every unit of medication aspirated or injected to or from an individual syringe. Hence, there is no need to look at the syringe, or bring it to the eye level, during use thereof. In some embodiments, a second set of detents is included, and in some embodiments a third set of detents is included. Syringe plungers useful for combining with a syringe body to produce such an incremental syringe are also described.

The subject invention provides a drug delivery device for injecting medicament which includes a tubular reservoir; a stopper slidably disposed in the reservoir; a spring for moving the stopper in the reservoir; at least one needle, the needle having a distal end for insertion into a patient, and a lumen extending proximally from the distal end, the lumen being in direct or indirect communication with the reservoir; a needle driver for displacing the needle; and an actuator. Activation of the actuator causes the spring to move the stopper and the needle driver to displace the needle. The needle moves relative to, and separately from, the reservoir with the needle being displaced. Advantageously, with the subject invention, a drug delivery device is provided wherein a needle is moved, relative to the reservoir, in being displaced for injection. This permits control of the needle displacement separate from the reservoir.

A power pack for use with a medicament delivery device is presented having a plunger rod movable along a longitudinal axis; a drive spring operably connected to said plunger rod; a plunger rod sleeve arranged with holding elements for releasably holding said plunger rod with said drive spring in a tensioned state. Signal initiating elements are arranged to said plunger rod; and signal generating elements arranged to cooperate with said signal initiating elements for providing information to a user of a medicament delivery device about the movement of said plunger rod when said plunger rod sleeve has been activated to release said holding elements.

A device (1) for monitoring the state of an injection applicator comprising an energy source (10) and the following electronic components: an accelerometer (5), a time measuring means (6), a temperature measuring means (7), a processing unit (8) connected to a system adapted to store, process and transfer data, said system including: the time measuring means (6), the accelerometer (5), the temperature measuring means (7) and a memory (9), a user interface (4) connected to the processing unit (8) for presenting information based on the data transferred by the processing unit (8), said monitoring device (1) being connected to a control member (3) of the applicator, and wherein said monitoring device (1) is adapted to operate in a sleep mode and in an active mode, and is further adapted to detect by means of the accelerometer (5) at least a first action and a second action, the first action being related to taking said monitoring device (1) out of the sleep mode and putting it into the active mode, and the second action being related to the setting and/or the delivering of a dose.
