Abstract
A medicament delivery device for injecting a medicament is described. The medicament delivery device comprises a housing having a proximal end and a distal end, the housing being configured to receive a medicament container. A plunger is moveable in a longitudinal direction within the housing for dispensing medicament from the medicament container when the medicament container is received within the housing. A plunger drive magnet is operatively coupled to the housing, and the plunger drive magnet is configured to provide a magnetic field. A component is configured to magnetically interact with the magnetic field of the plunger drive magnet so as to cause a force to be exerted on the plunger for causing the plunger to move in the longitudinal direction.
