1. A fluid delivery device for administering a first medicament and a second medicament, the fluid delivery device comprising:
- a housing;
a first fluid reservoir configured to contain the first medicament within the housing;
a second fluid reservoir configured to contain the second medicament within the housing;
a needle having a first end configured to extend into the first fluid reservoir and a second end configured to extend from the housing;
a basal pump chamber having hydraulic fluid and coupled to the first fluid reservoir;
a basal drive mechanism having a hydraulic fluid reservoir, the hydraulic fluid reservoir including hydraulic fluid;
a flow restrictor fluidly coupling the hydraulic fluid reservoir with the basal pump chamber, the basal drive mechanism configured to pressurize the hydraulic fluid in the basal pump chamber and engage the first fluid reservoir to provide a basal delivery of the first medicament; and
a bolus drive mechanism coupled to the second fluid reservoir and configured to provide a bolus delivery of the second medicament.
