An infusion device with a dose reset mechanism, the device receiving a container containing a drug to be infused, a housing and a container housing, disposed within the housing, and capable of axial movement of a threaded piston rod A drive unit including a threaded piston rod operating in cooperation with a runner, a ratchet, a nut, and a threaded piston rod having a thread that is axially fixed in the housing and fits the thread of the nut, and a housing A dose adjustment element that is connected to the ratchet that is functionally connected to the nut and that is connected to the nut by means of a clutch sleeve and works in cooperation with the display element, the display element being fixed in its initial position. A dose adjustment element having a starting position and the action of the dose adjustment element so that energy is stored in the spring means A spring means connected to the housing and the dose adjustment element, a reset clutch, movable relative to the housing, so as to release the accumulated energy in the spring means by releasing a nut and a threaded piston rod The reset clutch is formed as a molded connecting element that is moved and axially slid using a dose adjusting element, and the reset clutch is operably connected to the drive unit. The drive unit cooperates with the spring means so that when the reset clutch is released, the connection is disconnected from the spring means which maintains the connection between the display means and the spring means which automatically takes a fixed starting position thereafter. An infusion device that operates.投与量リセット機構を備える注入装置であって、装置は、注入される薬を含むコンテナを受容する、ハウジング及びコンテナハウジングと、ハウジング内に配置され、かつ、ねじ状ピストンロッドの軸方向移動を可能にするランナーと共同で動作するねじ状ピストンロッドと、ラチェットと、ナットと、ハウジング内で軸方向に固定されナットのネジ山に適合するネジ山を有するねじ状ピストンロッドとを含むドライブユニットと、ハウジングに機能的に接続され、ナットに機能的に接続されたラチェットにクラッチスリーブを用いて接続され、表示要素と共同で動作する投与量調節要素であって、表示要素はその最初の位置に固定の開始位置を有する、投与量調節要素と、投与量調節要素の動作でスプリング手段にエネルギーがたまるように、ハウジングと投与量調節要素とに接続されたスプリング手段と、リセットクラッチと、ハウジングに対して移動可能で、ナットとねじ状
