1. A fluid delivery device for administering a first medicament and a second medicament comprising:
- a housing;
a first reservoir within the housing and configured to contain the first medicament;
a second reservoir within the housing and configured to contain the second medicament;
a first basal drive mechanism within the housing and having a first hydraulic fluid reservoir;
a first pump chamber in fluid communication with the first hydraulic fluid reservoir of the first basal drive mechanism via a first flow restrictor, the first pump chamber configured to engage the first reservoir to provide a basal delivery of the first medicament during use;
a second basal drive mechanism within the housing and having a second hydraulic fluid reservoir;
a second pump chamber in fluid communication with the second hydraulic fluid reservoir of the second basal drive mechanism via a second flow restrictor, the second pump chamber configured to engage the second reservoir to provide a basal delivery of the second medicament during use; and
a needle having a first end configured for fluid communication with the first reservoir and a second end configured to extend exteriorly from the housing.

Abstract
A fluid delivery device for administering a first medicament and a second medicament includes a first fluid reservoir configured to contain the first medicament and a second fluid reservoir configured to contain the second medicament. The fluid delivery device may include one or more basal drive mechanisms to provide a basal delivery of one or more of the first and second medicaments. The fluid delivery device may further include one or more bolus drive mechanisms to provide a bolus delivery of one or more of the first and second medicaments.
