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 an inlet check valve, a first outlet check valve downstream of the inlet check valve, and a piston pump disposed between the inlet check valve and the first outlet check valve. The piston pump is configured to prevent partial dosing of a bolus dose.
