Abstract: An injection device, in some embodiments an autoinjector, which includes a housing, an actuating sleeve carried by the device to be movable relative to the housing and which can be placed at a point of injection in a position of insertion, an injection needle extendable from the end of the injection device when the injection device is in the position of insertion and moveable into the interior of the injection device, and an actuating cam arranged in an axially fixed manner relative to the injection needle and engageable in a locking recess when the injection device is in the position of insertion to prevent the injection needle from being moved into the interior of the injection device, said actuation cam being releasable from engagement with the locking recess by the actuating sleeve, thereby releasing the injection needle for movement into the injection device.

Abstract: A brake mechanism for an injection device for generating a braking action on a moving, e.g. rotating, part or component of the injection device.

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: A dosage indicator for a device for the metered administration of a dose of a substance, comprising a rotatably movable metering element for adjusting the dose to be administered, an indicator element for indicating the adjusted dose, and a coupling device having a carrying element moveable rotatably about a first axis of rotation and at least one rotatable engagement element disposed on the carrying element for the mechanical coupling of the indicator element and the metering element, wherein the at least one engagement element can be rotated about a second axis of rotation on the carrying element said second axis of rotation extending transversely to the first axis of rotation.

Abstract: An injection device for administering a liquid product, the device including a drive mechanism, an engaging member and a catch including a number of latching elements, wherein at least one of the engaging member and the number of latching elements is relatively moveable to the other to generate a haptic and/or acoustic signal comprising a number of discrete signals during a relative movement, wherein one of the catch and the engaging member is coupled to the drive mechanism and the drive mechanism generates a variable drive speed during the relative movement, and wherein the latching elements are a distance (x0; x0-?x) from each other such that a time interval between each of the number of discrete signals is constant. A method for generating a haptic and/or acoustic signal in use of an injection device is encompassed.

Abstract: An injection device, in some embodiments an autoinjector, which includes a thrust spring that advances an injection needle from an initial position to an insertion position from the distal end of the injection device and that causes a product to be emptied from the product reservoir by an emptying movement, and a return spring that retracts the injection needle from the insertion position into the distal end of the injection device counter to the force of the thrust spring, wherein the return spring is decoupled from the thrust spring during the emptying movement.

Abstract: An injection device including a drive unit, a delivery unit, a dosing unit, a trigger for triggering an injection, a first coupling mechanism between the drive unit and the delivery unit, and a second coupling mechanism between the dosing unit and the drive unit, wherein the drive unit is tensioned by a rotation of the dosing unit and when the drive unit is tensioned the first coupling mechanism is disengaged and the second coupling mechanism is engaged, and wherein when an injection is triggered first the first coupling mechanism is engaged and then the second coupling mechanism is disengaged. In some embodiments, the device may include a third coupling mechanism which only releases the delivery unit after the engagement and disengagement which follow a triggering.

Abstract: An injection device for administering a substance from a replaceable container containing the substance, the device including a dosing unit for setting an amount of the substance to be administered, a delivery element, a dose limitation unit operably coupled to the delivery element, and a spring element, wherein the dose limitation unit prevents the setting of a last dose that exceeds a remaining amount of substance available in the container and wherein, when the product container is replaced, the dose limitation unit is automatically reset to a position corresponding to the amount of product available by the spring element moving the delivery element into an end position.

Abstract: An injection device including a housing and a delivery element guided in a liquid-tight manner in relation to the housing, the delivery element having a substantially smooth, cylindrical outer wall region and surrounded by at least one annular sealing element.

Abstract: An injection device including a housing, a delivery element displaceable in relation to the housing, and at least one ball bearing which absorbs forces transmitted between the delivery element and the housing, transmits axial forces from the delivery element to the housing, and is located in a front region of the injection device.

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.
