    • A limiting mechanism which prevents the setting of a dose, which exceeds the amount of liquid left in a cartridge of an injection device, is disclosed. The injection device is the type where a dose is set by rotating a dose setting member relative to a driver and away from a fixed stop in the injection device. The dose setting member interfaces the driver such that the dose setting member can be rotated in one direction without rotating the driver. The dose is injected by rotating back the dose setting member which during the backward rotation carries the driver with it. Rotating the driver causes the piston rod to move forward inside the cartridge and expel some of the liquid contained in the cartridge. The driver is provided with a track having a length which is related to the total amount of liquid in the cartridge and which track is engaged by a track follower coupled to the dose setting member to follow rotation of this dose setting member. Each time a dose is set and injected, the track follower moves further into the track. When the track follower reaches the end of the track the dose setting member can not be rotated further, and a dose larger than the remaining liquid in the cartridge cannot be set.
    • 公开了一种限制机构,其防止剂量的设定超过注射装置的药筒中残留的液体量。 注射装置是通过相对于驾驶员旋转剂量设定构件并远离注射装置中的固定止动件来设定剂量的类型。 剂量设定部件使驱动器接合,使得剂量设定部件能够在一个方向上旋转而不使驾驶员旋转。 通过旋转剂量设定构件来注射剂量,在剂量设定构件中,在反向旋转期间携带驾驶员。 旋转驱动器使得活塞杆在筒内向前移动并排出容纳在盒中的一些液体。 驱动器设置有具有与筒中的液体总量相关的长度的轨道,并且轨道由耦合到剂量设定构件的轨道从动件接合以跟随该剂量设定构件的旋转。 每次设定和注入剂量时,跟踪跟随器进一步移动到轨道中。 当轨道跟随器到达轨迹的末端时,剂量设定构件不能进一步旋转,并且不能设置大于盒中剩余液体的剂量。

    • A refillable injection device (1) having a dose setting mechanism with a dose setting member (4) and a dose rod (11). The dose setting member and the dose rod engage during normal operation of the injection device, and they do not engage during change of cartridge. The dose setting member and the dose rod need to be moved into engagement when a new cartridge is inserted in the injection device. Thereby there is a risk that stress is build-up in the piston rod. In order to prevent this, the cartridge holder is operatively connected to the dose rod in such a manner that when a cartridge is being inserted in the cartridge holder, the dose rod is caused to move along with the piston rod in an axial direction, at least while the dose setting member and the dose rod are moved into engagement.
    • 一种具有剂量设定构件(4)和剂量棒(11)的剂量设定机构的可再充注注射装置(1)。 剂量设定构件和剂量杆在注射装置的正常操作期间接合,并且在盒的更换期间它们不接合。 当新的药筒插入注射装置时,剂量设定部件和剂量棒需要移动到接合中。 因此,存在在活塞杆中产生应力的风险。 为了防止这种情况,药筒保持器以这样的方式可操作地连接到剂量棒,即当药筒被插入药筒保持器中时,剂量棒随着活塞杆沿轴向方向移动, 当剂量设定构件和剂量杆移动到接合中时最少。

    • The invention relates to an injection device for injecting a dose of drug. The injection device comprises a housing, a dose setting mechanism being operable to set a desired dose, an injection mechanism comprising a piston rod (7) adapted to cooperate with a piston positioned in a cartridge containing a drug to be delivered in order to cause a set dose to be delivered from the cartridge via the injection device, a dosage tube (6), and retaining means arranged to prevent axial movement of the dosage tube in a distal direction relatively to the housing during dose setting. The dose setting mechanism comprises a rotatable dose knob (24), operation of the dose setting mechanism causing energy to be stored in a spring member. The injection mechanism is driven by releasing energy previously stored in the spring member during dose setting.
