Patent ID: 8579861

Claim:
A needle magazine adapted for connection with a medical delivery device having a medicament reservoir and a device fluid access portion, the device fluid access portion, when the medical delivery device is coupled to the needle magazine, defining a needle mounting space in front of the device fluid access portion, the needle magazine comprising: a needle support structure adapted to couple with the medical delivery device, a plurality of injection needles supported by the needle support structure and forming a needle cluster, and needle positioning element operable to move a needle selected from the plurality of needles from a storage position outside said needle mounting space and into a needle mounting position in said needle mounting space thereby allowing the selected needle to connect to the device fluid access portion to establish fluid communication with the medicament reservoir, wherein the needle positioning element is configured to alter the relative position between a needle selected from said plurality of needles relative to a neighbour needle when said selected needle moves from its storage position to the needle mounting position, wherein the plurality of needles when positioned in their storage position forms an array where the mutual spacing between a needle and a neighbouring needle is defined by a first distance, wherein the needle positioning element, when moving a selected one of said needles from its storage position to the needle mounting position outside the needle mounting space and into the needle mounting position, moves said selected needle at least partly sideways relative to a respective neighboring needle so that the mutual distance between the needle in the needle in the needle mounting position to a neighbor needle is larger than said first distance, and wherein each needle is mounted in a respective needle hub connected to a pivot support structure, said pivot support structure being configured to pivot the needle hub into the needle mounting position responsive to actuation of the positioning element.
