An auto-injector device comprises a cap removal mechanism which comprises a retractable component which is slidably mounted within a housing of the device, and a cap-removal actuator to push the retractable component out of the housing to remove a cap from the device; a dispense mechanism which comprises a driving element to expel a medicament from the device; and a dispense button which activates the cap removal mechanism when pressed a first time, engages with the dispense mechanism when released, and activates the dispense mechanism when pressed a second time. The dispense mechanism comprises an engaging element configured to engage with the dispense button when the dispense button has been pressed for a first time and released.

A medicament injection device comprising: a main body configured to receive a medicament cartridge, a needle sleeve axially movable with respect to the main body, a needle holder holding a needle, and a displacement element coupled to the needle holder and disengageably coupled to the needle sleeve; wherein, upon axial displacement of the needle sleeve by a predefined distance in a proximal direction, the needle carrier and needle are displaced axially in a proximal direction.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a system includes an injection pen device including a dose setting mechanism, a dispensing mechanism, and an electronics unit to generate dose data associated with a dispensing event of a dose of the medicine dispensed from the injection pen device and time data associated with the dispensing event; a mobile device in wireless communication to receive and process the dose data; and a software application configured to determine a recommended dose based on health data and contextual data associated with a user of the injection pen device, the software application including a learning dose calculator module to adaptively calculate the recommended dose of the medicine based on time-relevant and circumstances-relevant data specific to the user of the injection pen device.

A pen needle assembly (10) includes a pen needle (12) with a hub body (16) having a needle shield (28) that covers a needle (26) and can be retracted to expose the needle during injection and return to the extended position after use and locked in the extended position. A spring (56) is provided to rotate the needle shield after use to a locked position. A locking member (84) can be provided on the needle shield that cooperates with the hub body (16) to prevent rotation after use. An attachment mechanism (38) for the pen needle provides a sensory indication when a needle-bearing hub body (16) is seated on a pen and limits further rotation of the pen needle relative to the delivery device.

The present disclosure relates to a cap for an injection device. The injection device comprises a body for holding a syringe having a needle extending from an end thereof. The cap is removably attachable to the body. The cap comprises an actuator and a needle shield to cover said needle. The cap further comprises a coupling between the actuator and the needle shield. The coupling is configured such that when the cap is attached to the body of an injection device axial movement of the actuator away from the body causes rotation of the needle shield relative to the body.

An injection device comprising: a housing arranged to contain a liquid medicament or a medicament cartridge; an electrical coil arranged at the housing; a removable cap arranged to be removably engaged with an end of the housing; and a magnet arranged within the removable cap; wherein when the removable cap is disengaged from the housing, the magnet moves with respect to the electrical coil such that electrical voltage is induced in the electrical coil and a current is generated.

A safety syringe (1) includes a sleeve assembly (10) threadedly secured to a vial (40) containing regular insulin and including an axial channel (12) with a needle assembly (20) placed therein, and two opposite pivot pins (14) formed on an outer surface. The needle assembly (20) includes a needle hub (22) formed on a front end, and a hypodermic needle (23) through the needle hub (22). A protective covering (30) includes two opposite arms (31) pivotably secured to the pivot pins (14), a space (32), a slot (33) parallel to the arms (31) and communicating with the space (32), and at least one lock member (34) at an end of the slot (33). After injection, a clockwise rotation of the protective covering (30) until the lock member (34) passes through the needle hub (22), and the hypodermic needle (23) passes through the slot (33) to conceal in the space (32).

A disposable pen needle, comprising a hub having a needle situated thereon having a patient end and a non-patient end, a removable patient end cap attached at the distal end of the hub, a removable non-patient end cap attached at the proximal end of the hub, wherein greater force is required to detach the patient end cap than is required to detach the non-patient end cap.

Safety needle device (1) comprising: a hub (10) configured to be connected to a pen-injector, the hub (10) comprising a lateral wall (11) and an upper wall (12) which define therebetween a cavity (13) extending between the upper wall (12) and an lower aperture (14) able to receive the pen injector; a needle (20) attached to the hub (10), the needle (20) extending along a longitudinal direction (X-X) between a distal end (21), configured for insertion into a patient, and an opposed proximal end (22) configured to be connected to the pen injector, a back-end shield (30) slidable along the longitudinal direction (X-X) within the cavity (13) of the hub (10) and rotatable about the longitudinal direction (X-X), the back-end shield (30) being movable irreversibly from an initial position, before connection of the pen injector to the hub (10), to a locking position, after removal of the pen injector to the hub (10) passing through an intermediate position, an elastic member (40) arranged within the cavity (13) and acting between the upper wall (12) and the back-end shield (30) to urge the back-end shield (30) towards the proximal end (21) of the needle (10) along the longitudinal direction (X-X), a locking arrangement (50) comprising at least a first locking member (60) formed on the back-end shield (30) and at least a second locking member (70) formed on the hub (10), the second locking member (70) cooperating with the first locking member (60) to guide the back-end shield (30) from the initial position to the locking position and to lock the back-end shield (30) in the locking position, the second locking member (70) comprises a passing through guide (71) formed on the lateral wall (11) of the hub (10); the first locking member (60) comprises a protrusion (61) configured to engage the guide (71) and to slide along the guide (71).

A drug delivery device (100, 300) for delivering a plurality of doses of a medicament, wherein a needle shield (110, 310) is operationally coupled to a hub driving structure (210, 430), a active needle assembly (220, 420), a pulling structure (230, 320) and a support structure (136, 336, 338, 350) such that the operation of the needle shield is adapted to drive the active needle assembly (220, 420) to the proximal position of the active needle assembly (220, 420), before the needle shield (110, 310) can reach the proximal position of the needle shield (220, 420), whereby fluid connection can be establish before the drive mechanism can be activated.
