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.

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.

Abstract: An actuation device for an administration device and/or an administration device for the parenteral administration of a medicament, includes a rotary element rotatable through an angle proportional to a dose volume, a pushing element configured to act on a drive, a magnetic element operatively connected to the rotary element and/or the pushing element and movable therewith relative the instrument housing, a sensor arrangement with at least three magnetic field sensors, each with a directivity with regard to the direction of a magnetic field component, and an evaluation device. At least a first and a second of the magnetic field sensors are fitted such that they selectively sense the changes in the field component in the circumferential direction and the at least third magnetic field sensor is fitted such that it selectively senses the changes in the field component in the axial direction.

Abstract: An autoinjector having a housing, a product container axially fixed in the housing, a torsion spring, a drive element, a propulsion member, and a needle protection sleeve which, when the autoinjector is pressed against a point of injection, carries out an actuation movement in the proximal direction. The autoinjector includes a display for signaling the progression or persistence of a discharge, with a display element, which is driven by the drive element, rotates about the longitudinal axis and has an optical contrast pattern, and a transparent window at the proximal end of the autoinjector, through which the rotating contrast pattern is visible. The window is completely circumferential by 360° about the longitudinal axis, i.e., is not interrupted by a frame or web parallel to the longitudinal axis, which otherwise creates a dead angle for the view on the display element.

Abstract: A dosing device for an injection device, the dosing device including an actuating element for adjusting and/or dispensing a dose from the injection device, a thrust element for generating a forward movement for discharging a dose and a coupling to which the actuating element and the thrust element are coupled such that a rotational movement of the actuating element is transmitted directly to the thrust element and an axial movement of the actuating element is different than an axial movement of the thrust element.

Abstract: An autoinjector for dispensing a liquid product includes a housing; a product container arranged in the housing, particularly, a syringe comprising a displaceable piston; a drive member; a first spring which acts on the drive member and the piston to dispense the product from the container; signal element releasably axially coupled with the drive member so that the signal element is transported in the dispensing direction as said drive member is displaced; and a second spring, which exerts a spring force on the signal element against the dispensing direction and is tensioned as the signal element is transported in the dispensing direction. When the signal element is released or detached from the axial coupling, the second spring causes the signal element to accelerate opposite the dispensing direction and strike against a signal stop and generate an acoustic and/or tactile signal.

Abstract: An autoinjector having a housing for receiving a product container, a propelling member, a drive for automatically discharging a liquid product, a needle-guard spring for pretensioning a needle-guard sleeve, a grid with a multiplicity of latch elements arranged along the longitudinal direction, and an engagement element which, by engagement in the grid, blocks a discharging movement of the propelling member. A control element of the autoinjector interacts with the engagement element via a control cam such that, when the control element moves in the distal direction by the needle-guard spring, the engagement element is brought into engagement with the grid. Since the force of the needle-guard spring is used for the engagement, the engagement element can be mounted without specific elastic force acting in an engagement direction, and can also be mounted in an articulated manner and/or in a manner limited to pure guidance in the engagement direction.
