Abstract: A medicament delivery device includes a housing with a circle-segment-shaped compartment for a drive unit that moves at least one stopper in a medicament container and that includes a support wheel and central hub on which first and second parallel disks are fixedly attached and interconnected by an abutment cross-wall; spherical members between the abutment wall and adjacent the stopper; a clock spring within the hub with an outer end connected to the hub and an inner end connected to a one-direction-rotatable tubular hub coaxially arranged around a shaft fixedly attached to a housing part; and an activation member connected to the first disk by a hold-and-release mechanism. When the activation member is not depressed, the wheel and spring are held in a tensioned static state, and when the activation member is depressed, the spring and wheel are released and the spherical members are forced against the stopper.

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.

Abstract: A control unit for a medical device wherein the control unit comprises a pump, a conduit and control means for controlling the flow of fluid from the pump through the conduit; and wherein the conduit is a rigid internal passage located in the control unit.

Abstract: The present invention relates to a device for delivery of medicament comprising a main housing, a container including at least two compartments, wherein each compartment contains a component of the medicament to be injected, and arranged to be connected to a patient delivery means, a longitudinally movable piston and a spring arrangement acting on said piston and capable of exerting a force on said components, a first holding means arranged and capable of holding said piston in a force-loaded state, and at least one activator means capable of acting on said first holding means for releasing said piston, characterised in that it further comprises a second holding means capable of stopping the movement of said piston when it has moved a certain first distance after one activation of the at least one activator means and holding said 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, in th
