    • The present invention relates to a medicament delivery device such as an injector for self-administration of a medicament. There is a need to display the amount of the dialled dosage of medicament on the rotatable knob in figures sufficiently large and clear to be legible by those users having a degree of impaired vision. There is disclosed a dose dial mechanism for a medicament delivery device having a housing (4), the dose dial mechanism comprising a dose dial element (6) having a first thread (40) for engagement with the housing (4) and a dial sleeve member (8) having a second thread (48) for engagement with the housing (4) in which the dial sleeve member (8) is coupled to the dose dial element (6) so as to allow relative axial movement and inhibit relative rotational movement therebetween, and in which the pitch of the second thread (48) is different from the pitch of the first thread (40) so as to cause a different axial displacement of the dial sleeve member during axial displacement of the dose dial element.
    • 本发明涉及一种药物输送装置,例如用于药物的自我给药的注射器。 需要在具有视力受损程度的那些使用者的足够大且清晰的图中的可旋转旋钮上显示拨药剂量的量。 公开了一种用于具有壳体(4)的药物输送装置的剂量拨号机构,剂量拨号机构包括具有用于与壳体(4)接合的第一螺纹(40)的剂量拨号元件(6) 构件(8)具有用于与壳体(4)接合的第二螺纹(48),其中拨盘套筒构件(8)联接到剂量拨号元件(6),以允许相对轴向移动并阻止相对旋转运动 并且其中第二螺纹(48)的间距与第一螺纹(40)的间距不同,从而在剂量拨号元件的轴向位移期间引起拨盘套筒构件的不同轴向位移。
