Abstract
Disclosed herein is a reservoir for use in a wearable drug delivery device having multiple chambers of potentially varying lengths or arrangement so as to efficiently utilize available space within a housing of the drug delivery device. Each of the chambers is connected to a fluid path and a liquid drug is drawn from each of the chambers by suction applied to the fluid path. Each of the chambers is fitted with a free piston which is moved within the chamber by the suction applied to the fluid path as it draws the liquid drug out of the chamber, thereby eliminating the need for a mechanical arrangement for moving the piston within each of the chambers.
