药剂递送装置
摘要：
本发明涉及药剂递送装置。该药剂递送装置包括外壳、针、药剂递送机构和致动器。该针可从回缩位置移动到延伸位置，在该回缩位置，该针完全被接收在该外壳内，在该延伸位置，该针从该外壳突出。该药剂递送机构包括各自被布置在该外壳中的储器和分配构件、第一偏置构件和第二偏置构件、以及第一锁定构件和第二锁定构件。该致动器可相对于该外壳从初始位置移动到中间位置，使得该致动器在该第一锁定构件上施加力以将该第一锁定构件从锁定状态推动到解锁状态，其中该第一偏置构件将该针从该回缩位置移动到该延伸位置。该致动器可相对于该外壳从该中间位置移动到第二位置，使得该致动器在该第二锁定构件上施加力以将该第二锁定构件从锁定状态推动到解锁状态，其中该第二偏置构件在该外壳内移动该分配构件，以在该储器包含药剂时从该储器分配药剂。
摘要（英）：

The present invention relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle, a medicament delivery mechanism and an actuator. The needle is moveable from a retracted position, wherein the needle is fully received in the housing, to an extended position, wherein the needle protrudes out of the housing. The medicament delivery mechanism comprises a reservoir and dispensing member each disposed in the housing, first and second biasing members, and first and second locking members. 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 the retracted position to the 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.
