Abstract
A fluid dispensing device useful as an inexpensive, light-weight ambulatory disposal drug infusion pump comprises a flexible reservoir for liquid to be administered parenterally to a patient, a mechanism for placing the liquid in the reservoir under a constant pressure for dispensing the liquid from the device, a distal septum for introducing liquid in the reservoir, and a flow control mechanism for adjustably controlling the flow rate of the liquid dispensed from the device.
