摘要：
The invention relates to a dose setting mechanism (1) for a drug delivery device (2), comprising a number of separate dose setting elements (3.1 to 3.n), wherein a dose volume and/or a dose number are/is set by moving at least one of the respective dose setting elements (3.1 to 3.n) from a stack position (I) to an initial position (II), and wherein a medicament dose volume is applied by moving at least one dose setting element (3.1 to 3.n) from the initial position (II) to a dispense position (III) and wherein the movement of the dose setting element (3.1 to 3.n) from the initial position (II) to the dispense position (III) is limited by at least a height (h) of the dose setting elements (3.1 to 3.n) in the initial position (II), wherein each dose setting element (3.1 to 3.n) comprises a plurality of bulges (B1 to Bm) on at least one surface side (S1), wherein the height (h) of each dose setting element (3.1 to 3.n) equals a sum of the thickness (D) of the dose setting element (3.1 to 3.n) and the bulge height (h1).本發明係有關於一種用於藥物傳輸裝置(2)的劑量設定機構(1),其係包含許多個別劑量設定元件(3.1至3.n),其中係藉由使該劑量設定元件(3.1至3.n)中之至少一個各自堆疊位置(I)移到初始位置(II)來設定劑量體積及/或劑量數,以及其中係藉由使至少一劑量設定元件(3.1至3.n)由該初始位置(II)移到分配位置(III)來施加一藥劑劑量體積,以及其中該劑量設定元件(3.1至3.n)由該初始位置(II)至該分配位置(III)的移動受限於該劑量設定元件(3.1至3.n)在該初始位置(II)時的至少一高度(h),其中每個劑量設定元件(3.1至3.n)包含在至少一表面側(S1)上的多個凸起(B1至Bm),其中每個劑量設定元件(3.1至3.n)的高度(h)等於該劑量設定元件(3.1至3.n)的厚度(D)與該凸起高度(h1)的總和。1...劑量設定機構2...藥物傳輸裝置3.1至3.n...劑量設定元件4...儲存堆疊5...容器6...活塞7...活塞桿8...塞子9...開孔B1至Bm...凸起M...藥劑S1...表面側
