1. A method of administering first and second medicaments from a fluid delivery device, the method comprising:
- forcing hydraulic fluid from a hydraulic fluid reservoir into a first pump chamber, the hydraulic fluid in the first pump chamber exerting a force on a first piston to expel at least a portion of the first medicament through an aperture of a first fluid reservoir and deliver a first basal delivery of the first medicament;
forcing hydraulic fluid from the hydraulic fluid reservoir into a second pump chamber, the hydraulic fluid in the second pump chamber exerting a force on a second piston to expel at least a portion of the second medicament through an aperture of a second fluid reservoir and deliver a second basal delivery of the second medicament.

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.

4. A method of administering first and second medicaments from a fluid delivery device, the method comprising:
-
delivering a first basal delivery of the first medicament, and delivering a second basal delivery of the second medicament, wherein the fluid delivery device comprises; 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. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
