Disclosed is an auto injector and a method for administering a medicament. The auto injector comprising: a housing; a cartridge receiver; a drive module coupled to move a plunger rod configured to move a first stopper; a temperature sensor configured to provide a temperature signal indicative of the temperature of the medicament in the cartridge; a processing unit configured to: receive the temperature signal; control the drive module to move the plunger rod from a first plunger rod position to a mix plunger rod position wherein the movement from the first plunger rod position to the mix plunger rod position is based on the temperature signal.

An injection device is described having a housing that receives a syringe having a boot that covers its needle. The syringe is biased by a return spring from an extended position to a retracted position. A drive spring advances the syringe from its retracted position to its extended position. A return spring restores the syringe to its refracted position. A releasable locking mechanism retains the syringe in its refracted position. A sleeve can be depressed to release the locking mechanism. A cap covers the sleeve, thus preventing the locking mechanism from being released. When the cap is removed, it takes the boot with it and no longer prevents the locking mechanism from being released. Then, the locking mechanism can be released and the injection cycle begun.

According to the invention, a safety device for a pre-filled syringe with an injection needle comprises of a support body adapted to mount the pre-filled syringe, a needle shield slidably arranged with respect to the support body, a retention and locking means (M) for retaining and locking the needle shield with respect to the support body in a first and a second advanced position (PA1, PA2) and in a retracted position (PR). The needle shield comprises an annular flange adapted to rest on the skin of the patient receiving an injection. The retention and locking means (M) are arranged at a distal end of the safety device.

An autoinjector includes a housing for receiving in use in a generally longitudinal loading direction a syringe assembly including a syringe carrier and a syringe, the syringe including a syringe body having a slideable internal piston for expressing a dose contained in the body through a needle at a forward end thereof; a drive mechanism for providing drive for operation of the autoinjector and being disposed generally within the housing and including a mechanical energy source and a winder element for being rotated to charge the energy source, and an input transmission train operational between the syringe assembly and the winder element in use, whereby loading of the syringe assembly into the housing rotates the winder element to charge the energy source.

The present disclosure relates to a medicament injection device (1) comprising a housing (3) arranged to receive a medicament container (11a), a needle cover (9) movable relative to the housing (3), from a retracted position, in which it engages the housing (3) and enables medicament delivery, to an extended position, a plunger rod (7), and a plunger driver (5) movable relative to the housing (3) from an initial position to a final position, and arranged to actuate the plunger rod (7), wherein the plunger rod (7) has a first guide arrangement and the housing (3) has a second guide arrangement, the first guide arrangement (7d) and the second guide arrangement being arranged to cooperate to guide movement of the plunger rod (7) relative to the housing (3), wherein the first guide arrangement and the second guide arrangement in a first stage provide a linear motion path for the plunger rod (7), enabling the plunger rod (7) to initially move in the axial direction and in a second stage provide a rotation motion path for the plunger rod (7), enabling the plunger rod (7) to rotate relative to the housing (3) to release the plunger rod (7) from the plunger driver (5), whereby the plunger driver (5) attains a released state enabling movement of the plunger driver (5) to its final position, wherein in the released state the plunger driver (5) is arranged to release the needle cover (9) from the housing (3) and to actuate the needle cover (9) to its extended position.

An injector (10) for injecting a medicament into a patient. The injector includes a container (18) defining a first chamber (22), which contains a fluid therein, and a second chamber (23). The injector also includes an injection conduit (126) configured for directing the fluid fired from the container into the patient. A transfer mechanism is operable by a user to transfer the fluid from the first chamber to the second chamber in a first stage of operation, and a firing mechanism is operable by the user for firing the fluid from the second chamber through the injection conduit in a second stage of operation. An energy source (62) is in powering association with the firing mechanism to drive firing mechanism in the first and second stages.

The present invention relates to a needle including: a needle hub having a needle with a distal tip; a ring for protecting the needle in one of a storage condition or end-of-use condition of the needle assembly; a foldable element for moving the protective ring; a biasing element for urging the foldable element from its folded configuration to an unfolded configuration; a retainer for maintaining the biasing element in an intermediate stressed state at least in the storage condition of the needle assembly; and a deactivating element for releasing said retainer at least at the end of the injection step. The invention also relates to an injection device including such a needle assembly and a container.

A reloadable auto injector for epinephrine injection is provided. The reloadable auto injector has a separate needle insertion and medicine injection drivers (1600) wherein needle insertion driver (1200) is configured to be re-activated upon reloading. A syringe is movably positioned in a housing between a first position in which the needle is accommodated inside the housing and a second position in which the needle protrudes outside the housing. A plunger rod (1500) is normally locked to a plunger rod tube (1100) by at least one deflectable locking member (1110). A syringe driver (1200) applies a force to the syringe to move the syringe together with plunger rod tube, plunger rod and plunger rod driver from the first position to the second position. In the second position, the locking member (1110) is unlocked and releases the plunger rod to thereby activate the plunger rod driver to advance the plunger rod in the syringe for delivering of medicament. A reload handle (1400) is connected to the syringe assembly so that user operation of the reload handle retracts the syringe to the first position and simultaneously reload the syringe driver to thereby ready the auto injector for delivering a further dose of medicament.

There is provided a cassette unit suitable for use with an auto-injector. The cassette unit comprises a cassette unit housing and a removable cap that in a capping position fits over and thereby, acts to close off, a needle projection aperture of the housing. The cassette unit housing has one or more first engagement features arranged for reversibly engaging one or more second engagement features of the removable cap for reversible lock engagement of the removable cap to the housing; and a shuttle lock control defining one or more blocking elements for selectively blocking movement of said first engagement features relative to said second engagement features. The shuttle lock control is axially movable relative to the cassette unit housing between a first ‘cassette unused’ position; a second ‘cassette unlocked’ position; and after replacement of the removable cap, a third ‘cassette used’ position, locating intermediate the first and second positions.
