Abstract
An apparatus for delivering fluids at a precisely controlled rate which includes a fluid dispensing component having a fluid reservoir for containing the fluids to be delivered and a reservoir fill component which can be removably interconnected with the fluid dispensing component. The reservoir fill assembly is uniquely designed to accept a vial component of conventional construction which is factory filled with the medicinal fluid to be delivered to the patient. The dispenser component embodies a highly novel fluid flow indicator that provides a readily discernible visual indication of fluid flow status through the device.
