    • A drug delivery device (100) includes a body (102, 116) having a reservoir (160) disposed therein for containing a medicament and an injection needle (152) for penetrating the skin of a patient, the needle (152) providing a path for the medicament between the reservoir (160) and the patient. The device (100) also includes a plunger (144) movable within the body (102, 116) for causing the medicament to be expelled from the reservoir (160), and a biasing means (140) for biasing the plunger (144) toward the reservoir (160), wherein in a pre-activated position, the biasing means (140) telescopes within itself, and upon activation, provides a force to the plunger (144) for expelling the medicament from the reservoir (160). The biasing means (140) is preferably provided in the form of a conical spring having a variable pitch.
    • 药物输送装置(100)包括具有设置在其中的用于容纳药物的储存器(160)和用于穿透患者皮肤的注射针(152)的主体(102,116),所述针(152)提供路径 用于储存器(160)和患者之间的药物。 装置(100)还包括可在主体(102,116)内移动的柱塞(144),用于使药物从储存器(160)排出;以及偏置装置(140),用于将柱塞(144)朝向 所述储存器(160),其中在预启动位置中,所述偏置装置(140)在其内部望远镜,并且在启动时,向所述柱塞(144)提供用于从所述储存器(160)排出所述药物的力。 偏置装置(140)优选地以具有可变间距的锥形弹簧的形式设置。
