Abstract
A device for delivery of medicament includes a main housing, a container having at least two compartments, each containing a component of the medicament to be injected, and arranged to be connected to a patient delivery element, a longitudinally movable piston and a spring arrangement acting on the piston to exert a force on the components, a first holding element for holding the piston in a force-loaded state, and at least one activator for releasing the piston, a second holding element for stopping the piston when it has moved a certain first distance after one activation of the at least one activator and holding the piston in that position, wherein the force from the piston/spring arrangement and the movement causes the compartments to communicate with each other and the components to mix.
