Abstract: The invention relates to an autoinjector for dispensing a liquid product, in particular a highly viscous medication, comprising: a housing, a product container, which is arranged in the housing and has a slidable piston, wherein the piston can be slid in a dispensing direction in order to dispense the product contained in the product container, a forward drive element, which acts on the piston as the product is being dispensed, a first spring, which is preloaded such that the product can be dispensed from the product container by the sliding of the forward drive element and the piston, and a rotation element, which is operatively coupled to the forward drive element, wherein the first spring acts on the rotation element in such a way that the rotation element is set into rotation in order to dispense the product, wherein the rotation element or the forward drive element has a thread having a variable pitch.

Abstract: A spring assembly for an administering device includes a driving spring configured as a spiral spring and a spring shaft. An inner end of the spring is rotationally fixedly attached to the spring shaft. A spring sleeve extends around the circumferential region of the spring, wherein the outer end of the spring is connected to the spring sleeve in a rotationally fixed manner and a disk-type spring-sleeve cover is attached to the spring sleeve or the spring shaft. The flange and the spring-sleeve cover extend radially away from an axis of the spring shaft and the flange is arranged near a distal end of the spring shaft. A radial stop is arranged on the flange periphery, and a blocking element is arranged on the spring sleeve to be complementary to the radial stop for releasably rotationally securing to each other when the blocking element and the radial stop engage.

Abstract: An injection device having a delivery element with an inner thread may be driven by rotation and includes a cylindrical outer wall region, which is substantially smooth. Such features provide a delivery element configured such that it is less intimidating to patients than known threaded rods, and may facilitate easy cleaning. The delivery element may be non-rotatably guided and axially spring-loaded, and may be inserted axially into the housing when the reservoir is replaced. The driving thread element for the delivery element may be mounted in the vicinity of the distal end of the housing.

Abstract: A dosing mechanism for an injection device includes a dose-setting element with a first element coupled thereto, which, during dose setting, is rotatable relative to a second element about a main rotation axis in a first direction and, during dose discharge, is fixed in rotation relative to the second element. The first and the second elements are coupled via a sleeve-shaped stop element, which forms a stop abutment. The dosing mechanism includes a stop, and the stop abutment, during the rotation of the first element in the first direction, executes a movement to a stop position where the stop abutment strikes the stop and prevents rotation of the first element relative to the second element in the first direction of rotation. The sleeve-shaped stop element is rotatable about a secondary rotation axis, which is offset parallel to or offset at an angle to the main rotation axis.

Abstract: A driving and dosing device for an injection device for discharging a liquid product includes a housing, a rotatable dose adjustment member for adjusting a product dose to be discharged, a driven member received in the housing, a driving member rotatable relative to the housing and which, during the discharge of product, is coupled to the driven member such that a rotation of the driving member has the effect that the driven member is moved in the distal direction relative to the housing, a pretensioned driving spring which is switched between the dose adjustment member and the driving member during the adjustment of the product dose, wherein the dose adjustment member, during the adjustment of the product dose, is coupled in a rotationally fixed manner to the driving member, such that a rotation of the driving member relative to the dosing member is prevented.

Abstract: A blood lancing device includes a housing unit and a cap. When the cap is disposed at an initial position, a second drive element is blocked by a first drive element from forward movement relative to the first drive element. When the cap is moved from the initial position to a retracted position, the first drive element pushes the second drive element so that the second drive element is deviated from the first drive element when a holder holding a lancet is moved to a trigger position, thereby allowing for a high speed movement of the holder from the trigger position to a pricking position by virtue of biasing action of a first biasing member.

Abstract: 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.

Abstract: Drive and dosing devices for injection devices are disclosed. An embodiment may include a threaded piston rod moveable in a dispensing direction for dispensing a product. A rotation member may be operatively connected to a stop limiter and threadably engaged with the piston rod. Rotation of the rotation member may cause the piston rod to move in the dispensing direction. An embodiment may include a dose knob rotatable for changing a dose. The device may further include a stop element threadably engaged with the piston rod and having a catch. The dose knob may be coupled with the stop element such that during increase of a dose, the stop element is screwed toward the distal end of the piston rod and the catch is moved towards the stop limiter. The stop element prevents increasing a dose when the catch abuts the stop limiter.

Abstract: An injection device including a dosage setting element and a first element which is coupled to the dosage setting element and can be rotated relative to another, second element when a dosage is being set and is rotationally fixed relative to the second element when a dosage is being delivered, wherein the first element and the second element are coupled via a coupling member, and a stop abutment, wherein when a dosage is being set, the coupling member performs a movement toward a stop position, wherein the coupling member prevents a dosage from being set when it is in the stop position.

Abstract: 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.
