An injection device for dispensing a product, the injection device including a moveable element which is moved for a dispensing operation, a spring, a product container holder and a product container, wherein the spring pushes against the moveable element to move the moveable element to an initial position after the dispensing operation has ended and against the product container to seat the product container in the product container holder.

Dual-function spring

An apparatus and method for adjusting an injection device for administering a substance that includes a device housing with an array of fastening points. The apparatus has at least two housing-like shells, each having at least one holding device and at least one blocking device for attaching to the housing. The holding device of a first shell can be attached to a fastening point, and the holding device of a second shell can be attached to a further fastening point. Upon attaching all of the plurality of housing-like shells to the housing, the blocking devices of the plurality of housing-like shells prevent the disengagement of the plurality of housing-like shells from the housing by blocking detachment of the holding devices from the fastening points. At least one of the housing-like shells comprises an electronic assembly and shell attachment to the housing activates the electronic assembly.

Adjustable injection device

An adjustable injection device for administering a substance includes a housing with an array of fastening points and at least two housing-like shells, each having at least one holding device and at least one blocking device for attaching to the housing. The holding device of a first shell can be attached to a fastening point, and the holding device of a second shell can be attached to a further fastening point. The holding device of the first shell is prevented from disengagement therefrom by the blocking device of the second shell, and the holding device of the second shell is prevented from disengagement therefrom by a blocking device of a further shell, or, in the event that the injection device has only two shells, is prevented from disengagement from the further fastening point by a blocking device of the first shell whereby the shells are non-detachably connected to the housing.

Driving and dispensing devices for an injection device are used for administering a liquid product and adjusting a product dose and include a dosage display element with a helical dosage scale; an indication device for indicating a dosage value from the dosage scale; and a dosage element, which can be held by a user and screwed relative to the indication device around a rotational axis (L) and relative to the dispensing member along the rotational axis (L) in order to adjust the dosage to be administered. A bearing element having a thread is in a threaded engagement with a thread of the dosage indication element, and the thread pitch of the thread of the dosage indication element is not the same as the pitch (P) of the helical scale, and may be greater or smaller than the pitch (P) of the helical scale.

Injection device having a helical or spiral dosage scale

A brake mechanism for an injection device for generating a braking action on a moving, e.g. rotating, part or component of the injection device.

Brake for injection devices

An ampoule for use with an administering device such as an injection or infusion apparatus, at least two recognition elements associated with the ampoule, each of which at least two recognition elements can be arranged in one of at least two predetermined positions relative to the ampoule, wherein the at least two predetermined positions are asymmetrically located relative to the ampoule, and an administering device such as an injection or infusion apparatus which can be coupled to the ampoule. In one embodiment, the administering device has at least two associated sensors at predetermined positions in order to recognize the arrangement of the at least two recognition elements associated with an ampoule and, in another embodiment, the administering device has at least one sensor which can be moved relative to an ampoule.
