A discharger comprising a housing, a piston arranged inside the housing and being movable between a first piston position and a second piston position, a hollow cylindrical container inside the housing, the container being movable between a first container position and a second container position, a first compartment defined within the housing, a second compartment defined within the container, an axially extending passage in the interior of the piston and in communication with the first compartment and a peripheral opening of the piston in the region of a proximal end of the piston, a sealing element configured to prevent communication between the second compartment and the peripheral opening of the piston when the container is in a first container position, and a releasable retaining device configured to retain the piston in a piston first position until the container has reached a second container position.

The present disclosure relates to a medicament delivery device comprising a housing, a reservoir for medicament disposed in the housing and a dispensing member. The dispensing member is moveable relative to the housing from a first position to a second position to dispense medicament from the reservoir when the reservoir contains medicament. The medicament delivery device further comprises first and second biasing members. The first biasing member is configured to urge the dispensing member from the first position to an intermediate position. The second biasing member is configured to urge the dispensing member from the intermediate position to the second position.

The present disclosure relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle, a medicament delivery mechanism and an actuator. The actuator is moveable relative to the housing from an initial position to an intermediate position such that the actuator exerts a force on the first locking member to urge the first locking member from a locked state to an unlocked state wherein the first biasing member moves the needle from a retracted position to an extended position. The actuator is moveable relative to the housing from the intermediate position to a second position such that the actuator exerts a force on the second locking member to urge the second locking member from a locked state to an unlocked state wherein the second biasing member moves the dispensing member within the housing to dispense medicament from the reservoir when the reservoir contains medicament.

Disclosed is an injection device of the type including a cylindrical body enclosing a reservoir containing a product to be injected, which is slidably mounted in the body, which is open at one end on an injection needle and is closed at its other end by a plunger mounted movable in translation in the reservoir under the action of a plunger rod provided with a control member, the surface of the distal end of the body being coated with adhesive capable of ensuring that this surface is held on the skin of a patient. This device is characterized in that it includes a mechanism for securing the needle, the activation of which is ensured by the adhesive when a withdrawal effort is exerted on the injection device.

A discharger for discharging a predetermined amount of fluid from a separate container including a discharge section defining a longitudinal axis and having a proximal end and a distal end and having a discharge passage for the fluid extending between an inlet opening and an outlet opening of the discharge section. The discharger further includes an intermediate section including a distal portion cooperating with the proximal end of the discharge section and a proximal portion defining a receiving space which is adapted to be loaded with the separate container holding an amount of fluid to be discharged by the discharger. The distal portion and the proximal portion are formed in one piece and are interconnected by a breakable section.

A container assembly for containing and delivering a medicament is described. The container assembly includes a container having a first end and a second end. The first end includes an opening, and a plunger assembly at least partially disposed in the container. The plunger assembly includes a main body and at least one resilient portion at least partially retained by a groove in the main body. The resilient portion forms a seal with the container. The plunger assembly forms a temperature resilient seal with the container such that the container assembly is operable to contain a medicament between the seal and the opening at: (a) room temperature, and (b) during freeze storage of the medicament. The plunger assembly is moveable relative to the container at room temperature.

A system is disclosed for inserting a pharmaceutical cartridge into a delivery device. Optionally the cartridge is inserted in an arbitrary orientation. Optionally, the system reorients the cartridge to a locked orientation. For example, a driver applies a torque to the cartridge to cause the reorienting. For example, said torque rotates the cartridge around an axis thereof until the cartridge reaches the locked orientation. Optionally, when the cartridge reaches the locked orientation an interference element on the cartridge interlocks with a complementary interference element on the delivery device to lock the cartridge in the locked orientation. Optionally when the cartridge is locked in the second orientation, the torque causes discharge the pharmaceutical.

Disclosed is an injection device for receiving a syringe therein and for delivering a dose of medicament from the syringe, the injection device including: an insertion driver configured to drive the syringe forwards within the injection device for inserting a needle of the syringe into an injection site; an interlock mechanism configured to retain the insertion driver in a primed state and, when actuated, to allow the insertion driver to drive the syringe forwards; and an interlock actuator moveable between a stowed position and an operable position and configured on movement from the stowed position to the operable position to couple to an actuation system such that movement from the operable position back towards the stowed position actuates the interlock mechanism.

The present disclosure relates to a medicament delivery device comprising a housing, a reservoir for medicament disposed in the housing and a dispensing member. The dispensing member is moveable relative to the housing from a first position to a second position to dispense medicament from the reservoir when the reservoir contains medicament. The medicament delivery device further comprises first and second biasing members. The first biasing member is configured to urge the dispensing member from the first position to an intermediate position. The second biasing member is configured to urge the dispensing member from the intermediate position to the second position.

An injection delivery device involves a body, a medication-containing vial within at least a portion of the body, the medication-containing vial having an open end and a closed end opposite the open end. The open end of the vial includes a seal that prevents medication contained therein from exiting the vial until delivery of the medication to a target injection site is desired. The injection delivery device also includes a plunger positioned near the open end of the vial and a needle having a passage therethrough, wherein the needle, plunger and vial are positioned relative to each other such that, during delivery of an injection, a portion of the passage will be within the plunger, and the plunger and needle will remain stationary relative to each other while the vial moves relative the plunger in a direction towards the target injection site.
