A drug injection device with a cartridge holder that automatically actuates a clutch that resets the drive mechanism upon cartridge replacement and allows preloading of the drive spring
An injection device for setting a dose of a medicament and for dispensing from a replaceable medicament cartridge, comprising:-an elongate main lumen housing the medicament-filled cartridge (6) and defining an axial direction (3, 4) A piston rod (11) disposed inside the main housing (11) and extending axially along the first axis (3) and operatively engaging the piston of the cartridge (6) A drive sleeve (100) rotatably coupled to the piston rod and biased in a rotational direction by a torsion drive spring (126)；-a reset member (40) A second shaft (3) radially displaced from the first axis (3) and parallel to the first axis between the proximal operating position (O) and the distal reset position (R) 4) in the axial direction A reset member which is displaceable and thereby switches the device between a reset mode and an operating mode；-a release member which is released to the distal end of the main housing (11) by a bayonet-type connection along the first axis (3) A removably mountable cartridge holder (140) comprising a side wall portion (147) with a radially outwardly projecting locking member (144) to radially adjoin the cartridge holder (140) And a cartridge holder (140) for axially engaging and shifting the reset member (40) positioned thereat, the reset member thus forming part of a clutch, the clutch including a ratchet member (60), medication member (30), drive sleeve (100) and dose dial (20/32) Thing after the cartridge is removed from the device, reset the drive mechanism makes it possible to preload the torsion drive spring manually, the injection device.薬剤の用量の設定および取り換え可能な薬物カートリッジからの投薬のための注射デバイスであって：－ 薬剤が充填されたカートリッジ（６）を収容し、軸方向（３、４）を画成する細長い主ハウジング（１１）と、－ 主ハウジング（１１）の内側に配置され、軸方向に第１の軸（３）に沿って延びてカートリッジ（６）のピストンと動作可能に係合する、ピストンロッド（１３０）と、－ ピストンロッドに回転方向に結合され、ねじり駆動ばね（１２６）によって回転方向に付勢される駆動スリーブ（１００）と、－ リセット部材（４０）であって、主ハウジング（１１）の内側で、近位作動位置（Ｏ）と遠位リセット位置（Ｒ）の間を、第１の軸（３）から径方向にずらされ第１の軸に対して平行な第２の軸（４）に沿って軸方向に変位可能であり、それによってデバイスをリセットモードと作動モードの間で切り替える、リセット部材と、－ 第１の軸（３）に沿ってバヨネ
