1. A fluid delivery device comprising:
a housing having a fluid reservoir configured to fluidly couple to a user; a hydraulic pump chamber having a hydraulic fluid and coupled to the fluid reservoir; an actuator coupled to the fluid reservoir through the hydraulic pump chamber and configured to selectively urge a plurality of doses of fluid from the fluid reservoir and into the user, a bolus button coupled to the actuator and configured to urge a predetermined volume of fluid from the fluid reservoir upon activation by the user, the bolus button configured to automatically lock relative to the housing after activation; and a bolus release button coupled to the bolus button and configured to unlock and reset the bolus button upon activation by the user, the bolus button being positioned on a first side surface of the fluid delivery device and the bolus release button being positioned on a second side surface of the fluid delivery device, the first side surface being generally perpendicular to the second side surface, wherein the actuator must be moved by the user in at least two distinct operations to actuate the actuator for each of the plurality of doses.
