Abstract

A valving arrangement is provided herein for regulating fluidics of modules usable in a combinatorial drug delivery device. The valving includes a slidable piston valve, adjustable to selectively seal an outlet path from a drug vial and a sealing port, in parallel to a vent, for selectively sealing an inlet path to the drug vial. Advantageously, the subject invention allows for applied negative pressure to adjust the valving to allow flow between serially-connected modules forming a drug delivery device.
