FLUID DISPENSING APPARATUS WITH FLOW RATE CONTROL

摘要

An apparatus for delivering fluids at precisely controlled rates to ambulatory patients. The invention comprises a housing having a fluid reservoir to contain fluids to be delivered to the patient, a novel stored energy membrane for expelling fluid from the reservoir and a unique flow control assembly in communication with the fluid reservoir for the precise infusion of pharmaceutical fluids to ambulatory patients at precisely controlled rates. The flow control assembly includes a novel rate control member having a plurality of fluidic micro-channels through which the fluid is selectively directed.
