Abstract: In a dose setting mode of a dose delivery device, a dose selector is rotated to turn a nut, which thereby moves backward along a thread of a piston rod through a first axial distance. A gearing mechanism transmits the axial movement of the nut to a connector that moves backward, without rotation, through a second axial distance. In a dose delivery mode of the device, the dose selector is pushed forward and drives the connector to move forward through the second axial distance. The gearing mechanism transmits the axial movement of the connector to the nut, which pushes the piston rod forward, without rotation, through the first axial distance. The gearing mechanism includes a first gear that rotates without axial movement relative to the housing, and a second gear that rotates without axial movement relative to the nut.

Abstract: A syringe device for ejecting a dose of a medicament, the syringe device comprising: a dose limiting mechanism arranged to interact with a dose ejecting mechanism to prevent ejection of a dose exceeding a set dose, and a safety mechanism, which is arranged such with respect to the dose ejecting mechanism that, if the dose limiting mechanism fails, the safety mechanism prevents ejection of a dose exceeding the set dose.

Abstract: An injection device is disclosed wherein a dose can be set by rotating a dose setting member, whereby a push button is elevated from one end of the device a distance proportional to the set dose from a position fixed relative to the housing, and wherein the set dose can then be injected by pressing the push button back to its non-elevated position, through which motion a screw will move approximately the same distance or a smaller distance. The invention provides a method of reducing the dose force and/or the push-button movement during injection.

Abstract: A medication dispensing device with a housing and a member wherein the member is moveable in a distal direction is useful in delivering medication to a patient. A fluid container can be used with the device and often has a moveable piston at one end and an outlet at the other. The member receives a force from a user and drives the piston in the distal direction to expel medication. An intermediate system is disposed between the member and the piston including a gear set that has a pinion in meshed engagement with a rack. The system allows the member to move a greater distance than the piston moves thereby increasing the force on the piston.
