1. A device for dispensing fluid to a patient comprising:
a first reservoir configured to provide a source of fluid under pressure;
a bolus flow path for the delivery of a bolus dose of fluid;
a large volume bolus reservoir in fluid communication with said bolus flow path and configured to receive fluid from said
first reservoir, said bolus reservoir being configured to elastically expand to pressurize fluid, store the pressurized fluid
and dispense the pressurized fluid; and
a patient operable actuator to release fluid from the bolus reservoir, said actuator being configured such that it does not
require effort to force the fluid out of the bolus reservoir and that when actuated by the patient, fluid is permitted to
flow out of the bolus reservoir to the patient without further action by the patient.
