Abstract: Disclosed herein are various embodiments of clutching mechanisms applicable to a dual reservoir pumping mechanism for a drug delivery device, the clutching mechanisms serving to allow translation of one of the reservoirs during the filling process and thereafter connecting the reservoirs together such that one can be driven relative to the other one by means of a leadscrew or other driving mechanism.

Abstract: Disclosed herein are structures for ensuring that the reservoir of drug delivery device is free from any residual air before the device is filled with a liquid drug and put into use. The structures described herein are designed to prevent air from entering the reservoir during the pendency of a shelf life of the drug delivery device and/or to remove any residual air that has entered the reservoir of the drug delivery device prior to it being filled with the liquid drug.

Abstract: Disclosed herein are devices and methods for causing the linear translation of a plunger through a reservoir containing a fluid. A flexible member, for example, a wire or a ribbon, is coupled to the plunger and extends through a wall of the reservoir toward which the plunger is being linearly translated. A pulling force on the flexible member caused by a drive mechanism causes the plunger to linearly translate toward the end wall of the reservoir, thereby forcing any fluid contained in the reservoir out of the reservoir through a fluid port.
