摘要：
Disclosed are examples of reservoir and reservoir systems usable with a wearable drug delivery device. An example reservoir may include a flexible component coupled to a shell component. The shell component may include drainage channels to facilitate extraction of the liquid drug from the reservoir. A reservoir system example may include an exoskeleton configured around a flexible reservoir to guide the expansion and collapse of the flexible reservoir. Alternatively, one or more rigid panels may be coupled to corresponding flat surfaces of the flexible reservoir to guide the expansion and collapse of the flexible reservoir. A further reservoir example may include a flexible thin film reservoir having peel-able restraints configured to seal off corresponding sections of the reservoir, sequentially break, enabling the liquid drug to sequentially fill corresponding sections in a controlled and predicable manner. A wearable drug delivery device example suitable for utilizing the described examples is provided.
