Provided herein is a housing assembly for a drug delivery device, including a first housing part having a first proximal end comprising a first engagement portion and a second engagement portion, a first distal end, and a first sidewall therebetween defining a first longitudinal axis and a first interior, the first sidewall comprising one or more windows therethrough; and a second housing part having a second proximal end, a second distal end comprising a third engagement portion and a fourth engagement portion, and a second sidewall therebetween defining a second longitudinal axis and a second interior.

An autoinjector (100′) for expelling a single dose of a drug from a held cartridge (600) comprising a piston (630). The autoinjector includes a needle shield (350, 380′) axially movable from an initial extended position via a triggering position to a trigger release position. The needle shield (350, 380′) is operatively coupled to a plunger release element (320′, 1320) cooperating with a plunger (310, 400) to define a releasable retaining mechanism that retains the plunger release element (320′, 1320) threadedly engaged with a base thread component (204′, 1204) in a predefined relative rotational and axial position and against rotational bias provided by an actuator (330). The needle shield (350, 380′) is configured for operating the retaining mechanism to release the retaining of the plunger release element (320′, 1320) and the base thread component (204′, 1204) from the predefined relative rotational and axial position upon the needle shield (350, 380′) being moved into the trigger release position.

A drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing, a dose setting element rotatable relative to the housing during dose setting and dose dispensing, a drive member coupled to the dose setting member via a clutch, and a piston rod coupled to the housing and to the drive member Further, the device further comprises a cartridge holder removably attached to the housing and a reset element, which is permanently rotationally constrained to the housing and rotationally constrained to the drive member during dose setting, and at least one spring acting on the reset element, such that, if the cartridge holder is detached from the housing, the reset element is axially moved relative to the housing into a position in which the drive member is allowed to rotate relative to the housing

The present disclosure is generally directed to a clicker arrangement for use in a drug delivery device, i.e. a handheld injection device for selecting and dispensing a number of user variable doses of a medicament. The clicker arrangement comprises a first element rotatable at least in a first direction and a second, non-rotatable element. The first element is axially displaceable relative to the second element between a first position and a second position. One of the elements comprises a clicker arm and the other comprises a protrusion wherein upon rotation of the first element in the first direction relative to the second element the clicker arm is elastically deflectable in a radial direction by the protrusion and relaxable in the opposite radial direction upon disengagement with the protrusion thereby generating an audible and/or tactile feedback signal.

The present invention relates to a dispensing speed control mechanism for use in an injection device. The injection device may have a housing (10, 30, 40; 40′; 40″; 40′″) and a drive member (70), which is driven by a power reservoir (100, 100′) and axially movable between a dose setting position, in which the drive member (70) is rotationally constrained to the housing (10, 30, 40; 40′; 40″; 40′″), and a dose dispensing position, in which the drive member (70) is rotationally de-coupled from the housing (10, 30, 40; 40′; 40″; 40′″). The speed control mechanism comprises friction means (42) for retarding the drive member (70) during dose dispensing depending on the axial position of the drive member (70). Further, the invention relates to an injection device with such a dispensing speed control mechanism.

An autoinjector is described that includes an outer body, a first trigger, an output needle, and a first compartment. The first compartment is positioned within the outer body and includes (i) a main body, (ii) a first biasing member coupled to the first trigger, and (iii) a protrusion positioned at a distal end of the main body. The autoinjector further includes a second compartment positioned in the outer body and in fluid communication with the first compartment and the output needle. The autoinjector also includes a second biasing member coupled to a second trigger. The first biasing member is configured to, upon application of force to the first trigger, automatically move an ampule in a distal direction relative to the main body to force the ampule against the protrusion, so as to break the ampule and allow a medicament to flow from the ampule to the second compartment.

Disclosed herein is a syringe device comprises (a) an outer housing, (b) a barrel, (c) a stopper, and (d) a plunger with one or more grooves.

The present invention relates to compositions and methods utilizing anti-TNF antibodies having a heavy chain (HC) comprising SEQ ID NO:36 and a light chain (LC) comprising SEQ ID NO:37 for use in the treatment or prevention of Type I Diabetes (T1D).

An apparatus comprises a body having an opening at a first end of the body. A plunger control grip is slidably coupled to a portion of the body circumference and configured to couple to a syringe plunger. The apparatus further comprises a cover pivotably coupled to the first end of the body, wherein in an open position the cover exposes a cavity configured to receive a syringe. A locking mechanism is pivotally secured to the cover, wherein the locking mechanism is configured to prevent forward movement of the plunger control grip when in a locked position and to enable forward movement of the plunger control grip when in an unlocked position. The unlocked position is activated by external contact with the locking mechanism and forward movement is in the direction toward the first end of the body.

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.
