Medicament delivery device

摘要

A medicament delivery device includes a housing; a drive force mechanism slidable in the housing's distal part; a member connected to the drive force mechanism for holding it in a loaded state and axially movable in relation to the distal part a predetermined distance by the housing's proximal part when the parts are moved toward each other; and an actuation member to be biased in relation to the distal part from a non-operating position partially protruding from the distal part to an operating position confined within the distal part. The actuation member can release the drive force mechanism from its loaded state, and is resiliently connected to the distal part such that it is always recoiled after being biased regardless of whether the actuation mechanism is released. The drive force mechanism is released only after the holding member moves and the actuation member is biased from non-operating to operating position.

1. A medicament delivery device, comprising:
a generally elongated housing, comprises a proximal housing part and a distal housing part movable relative each other; a drive force mechanism accommodated in the distal housing part and slidably arranged in relation to the distal housing part; a container filled with medicament arranged within the proximal housing part; a holding member operably connected to the drive force mechanism for holding the drive force mechanism in a loaded state and arranged to be axially moved in relation to the distal housing part a predetermined distance toward a distal end of the device by the proximal housing part when the proximal and distal housing parts are moved toward each other; and an actuation member configured to be biased in relation to the distal housing part from a non-operating position, in which the actuation member partially protrudes from the distal housing part, to an operating position, in which the actuation member is confined within the distal housing part; wherein the actuation member is operably connected to the drive force mechanism for releasing the drive force mechanism from the loaded state; the actuation member is resiliently connected to the distal housing part such that the actuation member is always recoiled after being biased regardless of whether the actuation mechanism is released; and the drive force mechanism is configured to be released from the loaded state only after the holding member axially moves in relation to the distal housing part and the actuation member is biased from the non-operating position to the operating position.
