Abstract: An injection device for dispensing a dose of a product by manually advancing a piston rod includes a dosing and dispensing mechanism having a housing with a longitudinal axis, a dosing sleeve mounted in the housing for adjusting and correcting the dose, a housing insert fixed to the housing and arranged inside the dosing sleeve, and a coupling sleeve mounted in the housing for driving the piston rod.

Abstract: A needle insertion and retraction mechanism for a medication delivery device includes a housing and a needle carrier holding a needle guided by the housing and moved along a needle axis. A first spring member is adapted to move the carrier in an insertion direction. A second spring member is adapted to retract the carrier in a retraction direction, opposite the insertion direction. A control element, linearly guided by the housing, moves transversely to the needle axis from a starting position, via a needle insertion release position, to a needle retraction release position. When the control element is in its starting position, the control element is coupled to the carrier to prevent the carrier from moving in the insertion direction. When the control element is in the release position, the control element is decoupled from the carrier and the first spring member drives the carrier in the needle insertion direction.

Abstract: Dosing device for an administration device with a limiting mechanism containing: a dosing sleeve with a first stop and a stop wheel with a second stop means adapted to continually and proportionally follow a movement of the dosing sleeve during dosing movements. During an ejection movement, there is no relative movement between dosing sleeve and stop wheel. The first stop and the second stop each describe a path curve by their movements such that the two path curves intersect in one point and the stops contact one another and tilt the stop wheel, thereby blocking the dosing movement of the dosing sleeve. The stop wheel comprises first and third sloped surfaces that may form first and second gear guidances with a clutch thereby returning the stop wheel to a non-tilted position during up or down dosing movements when the stops do not contact another.
