Publication number: 20230070045Abstract: The invention relates to an injection device for ejecting a predetermined plurality of fixed doses. The doses are expelled by moving a needle shield (30) in the proximal direction which releases a pre-strained torsion spring (115) to eject one of the predetermined doses at the time. The injection device is further provided with a number of integrated needle assemblies (70) which one at the time are brought to an injection position. The needle change mechanism (80,90) operating the needle assemblies is controlled by rotation of the needle shield which is rotatable between a locked and an unlocked position.Type: ApplicationFiled: February 16, 2021Publication date: March 9, 2023Inventors: Henrik Bengtsson, Ronan James Carroll, Bo Kvolsbjerg
