A reservoir module for an administering apparatus, the reservoir module including a rotational block which permits the rotational dosing movement in a first rotational direction and blocks the rotational dosing movement in a second rotational direction, wherein the rotational block includes at least one first rotational stopper and at least one second rotational stopper, the first rotational stopper and the second rotational stopper abut against one another in the end position of the dosage setting member, wherein the dosage setting member is moved away from the translational stopper by the permitted rotational dosing movement.

Reservoir module for an administering apparatus

An administering apparatus including a rotational block which, in the end position of the dosage setting member, permits the rotational dosing movement in a first rotational direction and blocks the rotational dosing movement in a second rotational direction, wherein the rotational block comprises at least one first rotational stopper and at least one second rotational stopper, the first rotational stopper and the second rotational stopper abutting against one another in the end position of the dosage setting member, wherein the at least one first rotational stopper is secured against rotating by the dosage setting member and the at least one second rotational stopper is secured against rotating by the casing.

Administering apparatus comprising a rotational block

An injection device including a housing with a reservoir for an injectable product, a delivery device used to dispense a product dose from the reservoir, and a dose metering member which, in order to select the product dose, can carry out a rotational displacement in relation to the housing in a first direction until it reaches an end position and can be displaced in an opposite second rotational direction, wherein the dose metering member is coupled to the delivery device in such a way that the latter, when actuated, dispenses the product dose that has been selected by means of the dose metering member, the injection device also including an anti-twist safety device which has at least one anti-twist stop and at least one anti-twist counter-stop, one of which is formed by the housing and the other by the dose-metering member, wherein the anti-twist stop and the anti-twist counter-stop come to rest against one another in the end position in order to prevent the rotational displacement of the dose metering member in the first rotational direction from continuing beyond the end position.

Injection apparatus with an end position-blocked dosage setting member

An administering apparatus for delivering a dosage of product including a casing with a reservoir for the product, a conveying device, a dosage setting member mechanically coupled to the conveying device and a stopper for the dosage setting member. The conveying device is formed by a driven device and a drive device. The driven device, a piston rod in one embodiment, is mounted by the casing such that it performs a delivery movement in the form of a delivery stroke in an advancing direction along a translational axis to deliver a product dosage selected using the dosage setting member. The delivery movement of the driven device is effected with the drive device, the drive device and the driven device being coupled. The dosage setting member is coupled to the driven device such that a rotational dosing movement of the dosage setting member and the driven device relative to one another about the translational axis effects a translational dosing movement of the dosage setting member along the translational axis relative to the driven device and the casing. A translational stopper is provided to limit the movement of the dosage setting member. A rotational block is provided which permits the rotational dosing movement in a first rotational direction but blocks the rotational dosing movement in a second rotational direction.
