Abstract

Devices and methods for administering a medication in fluid form, the systems and methods including a basal flow path and a bolus flow path in parallel to the basal flow path. The bolus flow path includes a combined piston pump and rotatable valve. The piston pump is configured to prevent partial dosing of a bolus dose.
