INJECTION DEVICES WITH AUTOMATIC PRIMING
20230158244 · 2023-05-25 ·

An injection device comprises a needle holder that supports a needle, and a vial holder that supports a vial. A spring urges the needle holder to move towards the vial holder but that movement is restrained by a latch until the time of use. Releasing the latch primes the device by allowing the needle holder to move, whereby a proximal end of the needle pierces a septum of the vial. The latch is preferably released by rotating an actuator. The same rotation preferably frees the needle holder and vial to be advanced axially relative to the actuator, whereby a distal end of the needle can be introduced into the skin of a subject. Compressed air from a tank may be used to drive the discharge of the vial. The air tank preferably surrounds the vial and provides a broad proximal surface, against which manual pressure can be applied to the device.

PEN NEEDLE WITH RETRACTABLE SHIELD
20220331527 · 2022-10-20 ·

A pen needle (30) for a delivery device includes a hub (32) supporting a needle (54) and a distal needle shield (70) that can retract to expose the needle during injection and return to the extended position after use and lock in the extended position to cover the needle. A proximal needle shield (0.102) moves from a retracted position to an extended position with respect to the hub to shield or cover a proximal end of the needle when the needle hub is separated from the delivery device. A spring (130) extends between the distal needle shield and the proximal needle shield to bias each needle shield to the respective extended position. The distal needle shield (70) is coupled to the proximal needle shield (102) in an initial position to retain the spring (130) in a compressed state. The distal needle shield (70) is depressed to disengage the distal needle shield from the proximal needle shield (102) so that the spring expands to an extended state and moves the shields to the extended positions. A locking member (142, 156) can be provided to lock the proximal needle shield (70) and distal needle shield (102) in the extended position.

SAFETY NEEDLES AND METHODS OF USE THEREOF

A needle protection assembly, adapted to protect a tip of a hypodermic needle, comprising a shield adapted, in a protected operative orientation of the needle protection assembly, to shield the tip of the hypodermic needle, a locking element including at least one slot, the slot including at least three surfaces corresponding to three operative orientations of the shield, at least one slot engaging element, functionally associated with the shield, the slot engaging element being disposed within the slot of the locking element and movable relative thereto, between the surfaces, so as to transition the shield between the three operative orientations, and at least one biasing element, adapted for axial biasing of the shield, wherein the three operative orientations include a storage operative orientation, an injection operative orientation, and a needle protection operative orientation.

SINGLE DOSE MEDICAMENT DELIVERY DEVICE
20230107287 · 2023-04-06 ·

A medicament delivery device configured to provide a variable single dose of medicament is disclosed. The medicament delivery device includes a main body and a syringe arranged in the main body, wherein the syringe comprises a medicament. The medicament delivery device further includes a removable cap and a plunger rod operatively arranged to eject the medicament through a delivery member i.e. an injection needle attached to the syringe. Still further, the medicament delivery device includes a tubular member coupled to the plunger rod. The tubular member is configured to rotate during removing of the removable cap, and the rotation releases the plunger rod thereby allowing the plunger rod to travel a predetermined distance so as to prime the medicament delivery device.

AUTOMATIC INJECTION DEVICE

An automatic injection device, including a housing arranged along a longitudinal axis and having a forward end and a rearward end, the housing is configured to receive a syringe including at least one syringe piston and a needle coupled to a forward end thereof; a plunger rod adapted to be retained with respect to the housing in an initial operative orientation; at least one resilient element arranged to forwardly bias the plunger rod relative to the syringe; a needle shield adapted for selectable axial displacement with respect to the housing along the longitudinal axis, whereas rearward displacement of the needle shield exposes the needle and forward displacement of the needle shield covers the needle; and a trigger element configured to be axially rearwardly displaced upon rearward displacement of the needle shield relative to the housing and thereby allow forward displacement of the plunger rod relative to the syringe under the urge of the at least one resilient element.

Drive unit for a medicament delivery device

A drive unit for a medicament delivery device is presented having an elongated plunger rod extending in a longitudinal direction, a drive force element capable of applying a drive force on the elongated plunger rod, and an actuator operably connected to the elongated plunger rod for releasably holding the elongated plunger rod in an energized state when the drive force element is exerting a drive force on the elongated plunger rod. An activator is operably connected to the actuator for releasably holding the actuator in a holding position where the actuator is designed to be movable from the holding position in a direction generally transversal to the longitudinal direction upon a displacement of the activator for releasing the plunger rod.
