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 and a second end, the first end split into a first uptake arm and a second uptake arm;
a bolus drive mechanism;
a first bolus pump chamber including a hydraulic fluid and coupled between the bolus drive mechanism and the first fluid reservoir; and
a second bolus pump chamber including a hydraulic fluid and coupled between the bolus drive mechanism and the second fluid reservoir,wherein the needle is fluidly isolated from the first fluid reservoir and the second fluid reservoir in an un-activated position, an end of the first uptake arm extending into the first fluid reservoir and an end of the second uptake arm extending into the second fluid reservoir to fluidly couple the needle with the first and second fluid reservoirs in an activated position, and the second end extending from the housing in the activated position.
