A drug delivery device comprises a medication container containing medication for delivery and a detachable unit having an electronic circuit with a microprocessor. The electronic circuit is open and non-operational when the detachable component is assembled on the drug delivery device; and the electronic circuit is closed and operational when the detachable component is detached from the drug delivery device. The detachment of the detachable unit is an essential step to operate the drug delivery device. The detachable unit can be an activation protection cap or a needle shield remover for an autoinjector device. Alternatively, the detachable unit can be a needle shield remover for a pre-filled syringe.

A cap for a medicament delivery device is presented having a cap body and a medicament delivery member shield remover arranged in the cap body. The medicament delivery member shield remover has a tubular body extending along an axis in an axial direction from a proximal end to a distal end and extending in a circumferential direction around the axis, a slit in the tubular body extending in the axial direction, and a first protruding element extending from the tubular body towards the axis, and a second protruding element. The second protruding element has two protrusions extending from the tubular body away from the axis. The two protrusions are arranged on opposite sides of the slit in the circumferential direction. The cap body has a tubular body extending in the axial direction with a slit extending in the axial direction and having a tapered portion that tapers towards the distal end.

A medicament delivery device is presented having a tubular housing comprising a distal end and a proximal end; a medicament container arranged with a medicament delivery member and placed in the housing, a cap removably arranged on the proximal end of the housing and configured to cover the delivery member; a drive mechanism configured to act on the medicament container to expel the medicament through the medicament delivery member upon the drive mechanism is triggered; an activation member arranged coaxially movable in relation to the housing, associated with the drive mechanism and comprising a proximal tubular portion which extends from the proximal end of the housing and wherein for triggering the drive mechanism the activation member is axially moved towards the distal end of the housing after removing the cap from the housing. The proximal tubular portion of the activation member has a resilient element arranged with friction.

A housing for a medicament delivery device is presented having a shell extending along an axis in an axial direction from a proximal end to a distal end, and a medicament delivery member guard moveably attached to the shell. The medicament delivery member guard extends in the axial direction from a proximal end to a distal end. The shell has a slit extending in the axial direction and the medicament delivery member guard has a protrusion extending in the axial direction, and/or the medicament delivery member guard has a slit extending in the axial direction and the shell has a protrusion extending in the axial direction. The medicament delivery member guard is configured to move in the axial direction from a first axial position relative to the shell (12) to a second axial position relative to the shell.

A cover assembly that covers a medicament delivery member of a medicament container. The assembly having a housing extending along a longitudinal axis, a proximal end and a distal end. A cover member bi-directionally movable along the longitudinal axis relative to the housing, where the cover member has a tubular portion arranged to protrude from the proximal end of the housing, a biasing element arranged between the housing and the cover member configured to move the cover member, a locking member having a fixed end which is pivotally arranged to the housing and a free end which is releasably connected to the cover member. The cover assembly also has an actuator unit connected to the housing configured to interact with the free end of the locking member such that the locking member is able to lock and unlock the cover member in different positions.

An automatic injection device for use with a syringe including at least one syringe piston and a needle coupled to a forward end thereof, comprising a housing element arranged along a longitudinal axis and having a forward end and a rearward end; at least one resilient element arranged to be located within the housing element; a needle shield selectably positionable with respect to the housing element; and a control unit adapted, when actuated, to be driven by the at least one resilient element for initially displacing the syringe relative to the housing element from a non-penetration position to a penetration position and thereafter displacing the at least one syringe piston in the syringe to effect drug delivery, and wherein the control unit is configured to be actuated upon axial rearward displacement of the needle shield with respect to the housing element.

A primary container assembly includes a primary container defining a body having a proximal end defining an opening configured to receive a plunger, a distal end opposite the proximal end and defining an outlet, and a chamber extending from the proximal end to the distal end that is configured to receive a drug. The primary container assembly further comprises a tube extending from a first end that is integrally attached to the distal end of the primary container to a second end opposite the first end, where the tube defines a channel extending from the first end to the second end. The primary container assembly also includes a hollow needle configured to penetrate skin of a patient.

An injector for delivering a therapeutic product may include a base having a flexible surface that conforms to various body contours of a patient and defines one or more an injection chambers. The injector may have a height that is substantially less than its width, thereby defining a low profile, which provides a larger more stable base that can pinch or stretch the skin in a controlled manner. The larger base can also accommodate larger volumes via multiple injection chambers and/or large combined primary containers.

An injection device for injecting a substance into a body, including a syringe having: a needle, a barrel, a stopper, a plunger rod, moveable from an initial position to a final position, a needle shield, moveable at least from a retracted position to a safety position, a locking unit, arranged to lock the needle shield into the safety position, a locking actuator moveable at least: from a non-actuating position, into which the locking unit is in an open mode, to an actuating position, into which the locking actuator is arranged to put the locking unit in closed mode so that the needle shield can be locked into the safety position.

A disposable safety syringe needle and a syringe device including the same are provided, which can prevent reuse and an accident in safety, in which injury can be sustained by the needle. The disposable safety syringe needle includes: an upper part to which an elastic member is coupled and in which a needle member is inserted; a lower part which is coupled to one end of the upper part, and which includes one or more catching parts; and a safety part which is coupled to one end of the lower part, and which includes a catching protrusion, wherein the safety part is inserted into the lower part toward the upper part so that the elastic member is compressed, and the catching protrusion of the safety part is coupled to the one or more catching parts by the stretching force of the elastic member so as to disable reuse.
