A needle assembly has distal and proximal ends. The needle assembly comprises a body element having distal and proximal ends, an attachment means configured to be attached to a medication delivery device, a button element which is movable from a first position to a second position, and a needle configured to move to the distal direction, when the button element is moved from the first position to the second position.

Needle assembly and medication delivery system

A medication delivery device () comprises an indicator element () having indications () and a magnifying device located over an indication position (). The magnifying device () comprises an optical system () with a magnifying lens () wherein the optical system () is constructed such that the optical path length between the indication position () and the magnifying lens () is enlarged. As an example, the medication delivery device () is a pen-type device, wherein a dose dial element () having a dosage scale () is disposed. The magnifying device () generates a magnified image of the dosage scale () so that the size of the selected dose () of the medical product is visible through a window (). A method for assembling the medication delivery device () includes providing a medication delivery device () having a receptacle and mounting an element of the magnifying device () at the receptacle.

Medication delivery device and method of assembling a medication delivery device

The present invention relates to a drive mechanism for a drug delivery device for dispensing of a dose of a medicinal product, comprising: a holder for a product-containing cartridge, the cartridge having a piston slidably arranged therein in an axial direction, a piston rod to be operably engaged with the cartridge's piston for dispensing of a dose of the medicinal product, an adjusting assembly adapted to eliminate axial clearance between the piston and the piston rod, wherein the adjusting assembly comprises at least one radially extending spike element for mutually locking in position the piston and the piston rod irrespective of the relative distance between piston and piston rod.

Drive mechanism for drug delivery devices

The present invention relates to a drug delivery device for dispensing of a predefined dose of a medicinal product, comprising: a housing, a cartridge holder adapted to receive a cartridge containing the medicinal product to be dispensed, the cartridge holder being connectable to the housing, a drive mechanism to be operably engaged with the cartridge for setting and/or dispensing of a predefined dose of the medicinal product, wherein the drive mechanism is axially slidingly supported in the housing for compensating axial clearance between the drive mechanism and the cartridge and wherein the drive mechanism is axially fixable relative to the housing.
