A medicament delivery device (100) for the delivery of medicament from a container (12) through a cannula (16). The device comprises a chassis (300), a carriage (200), and an insertion spring (70) for biasing the carriage (200) for movement in an insertion direction with respect to the chassis (300) from a starting position in which the cannula (16) is shrouded to an insertion position in which the cannula (16) is extended. A drive mechanism (400) is provided for driving the container's stopper (22) to expel medicament. The drive mechanism (400) is carried by the carriage (200) and comprises a movable drive member (404), a drive means (40) for applying a driving force to the drive member (404), and force transmission means (406) for transmitting the driving force to the stopper (22). The drive means (40) is arranged around or alongside at least part of the force transmission means (406).

Medicament delivery device

The present disclosure relates to a medicament delivery device. The medicament delivery device includes a needle for delivering a medicament and an insertion mechanism configured to urge the needle in a first direction parallel to a longitudinal axis of the needle. The insertion mechanism includes a driving mechanism and a cam. The driving mechanism is configured to exert a force in a second direction perpendicular to the first direction. The cam is coupled to the needle and is configured to receive a force from the driving mechanism and move in the first direction in response to the received force.

AUTO-INJECTOR AND RELATED METHODS OF USE

An auto-injector may include a housing having a longitudinal axis and a transverse axis, the housing having a shorter dimension along the transverse axis than along the longitudinal axis, wherein the transverse axis is perpendicular to the longitudinal axis; a flowpath having a first end and a second end; and a container enclosing a first fluid, the container extending from a first end toward a second end along or parallel to the longitudinal axis and being movable from a first position to a second position along or parallel to the longitudinal axis, the container being fluidly isolated from the flowpath in the first position and fluidly connected to the flowpath in the second position.

Medicament injector and interchangeable cartridges therefor

The present invention relates to a medicament injector including an applicator with a cartridge-accepting receptacle. The medicament injector includes interchangeable, pre-filled medicament-containing cartridges. Each cartridge includes at least one barrier member having a closed position in which access to the medicament is inhibited. The barrier member is moveable from the closed position to an open position, in which the medicament is accessible via the applicator, when the cartridge is inserted into the cartridge-accepting receptacle. The barrier member moves back to the closed position when the cartridge is removed from the cartridge-accepting receptacle. This allows for a plurality of pre-filled medicament cartridges to be selected on demand via a need-based scenario for quick assembly with the medicament injector for use in various clinical scenarios to reduce the bulk, errors, complexity, and steps in medicament delivery while increasing the versatility, safety, and speed of medicament delivery in time critical situations.

CONNECTION STRUCTURE AND LIQUID MEDICINE ADMINISTRATION TOOL
