摘要：
The invention refers to an injection device (1) for automatic spring driven injection of a liquid drug by which doses of an individual size can be set by a user, the injection device (1) comprising: a housing (3) defining an interior space and having a longitudinal window (7), a rotatable dose dial (2) axially retained in relation to the housing (3), a rotatable scale drum (4) carrying indicia (6) for indicating the size of the set dose, wherein the scale drum (4) is functionally coupled to the dose dial (2) to rotate when the dose dial (2) is rotated to set a dose, a sliding element (11) provided with a sliding window (12), which sliding element (11) is adapted to slide axially in relation to the housing (3) during dose setting, and through which sliding window (12) the indicia (6) carried by the scale drum (4) is visible such that the longitudinal window (7) and the sliding window (12) in combination with the indicia (6) form a dose size display, and wherein the scale drum (4) rotates within the interior space defined by the housing (3) during dose setting and wherein the inner surface of the sliding element (11) is provided with an internal feature (29) engaging an external thread (5) provided on the outer surface of the scale drum (4) and wherein the sliding element (11) is further axially guided in the housing (3) such that the sliding element (11) moves axially when the scale drum (4) is rotated, wherein a drive spring (14) is attached to the scale drum (4) with one end and to the housing (3) with another end such that relative rotation between the scale drum (4) and the housing (3) charges the drive spring.本發明涉及用於液體藥物的自動彈簧驅動注射的注射裝置(1),使用者通過該注射裝置(1)能夠設定各個大小的劑量,該注射裝置(1)包括:殼體(3),其限定內部空間並且具有縱向視窗(7);可旋轉的劑量刻度盤(2),其相對於該殼體(3)在軸向上被保持;帶有用於指示設定劑量的大小的標記(6)的可旋轉的刻度滾筒(4),其在功能上耦接到劑量刻度盤(2),以在劑量刻度盤(2)旋轉以設定劑量時旋轉;滑動元件(11),其設有滑動視窗(12),並且適合於在劑量設定期間相對於殼體(3)在軸向上滑動,並且通過滑動視窗(12),能夠看到刻度滾筒(4)帶有的標記(6),以便縱向視窗(7)和滑動視窗(12)結合標記(6)形成劑量大小顯示器,並且其中刻度滾筒(4)在劑量設定期間在殼體(3)限定的內部空間中旋轉,並且滑動元件(11)的內表面設有與
