  • Patent number: 10493212
    Abstract: An autoinjector comprises a housing, a product container, a displaceable needle protection sleeve, a plunger rod displaceable by a preloaded discharge spring, a dose setting element with at least two different rotational positions relative to the housing, and a dosing sleeve. The dosing sleeve or the plunger rod has a dose selection stop, and the other has at least one dosing stop. By rotating the dose setting element, the dosing sleeve or the plunger rod is rotated relative to the other. Upon displacement of the needle protection sleeve, the spring displaces the plunger rod, whereby, if the dose setting element is in the first rotational position, the dose selection stop and the first dosing stop strikes against each other, and, if the dose setting element is in the second rotational position, one of the dose selection stop and the first dosing stop is or can be moved past the other.

  • Patent number: 8721601
    Abstract: A dosing device for setting a dose to be delivered by an injection device, the dosing device including a setting element, e.g. a setting sleeve, and a drawing element, e.g. a rotating sleeve, which can be rotated out of the dosing device for preparing a dose delivery. A stop is on the setting element, and a counter stop is on the drawing element so that a rotational motion of the drawing element relative the setting element can be limited by the stops. The present invention encompasses a method for setting a dose that should be delivered by an injection device, wherein the dose to be delivered can be set by a setting element, e.g. a setting sleeve, and a drawing element of the injection device, e.g. a rotating sleeve, can subsequently draw up the dose by effecting a rotational motion to deliver the set dose from the injection device in a subsequent step. According to the present invention, the setting process is isolated from drawing process.
