Abstract: A distal rate control device, which can be conveniently interposed between a fluid supply line and fluid delivery line for precisely controlling the rate of fluid flow toward the delivery line. The device includes a readily adjustable flow rate control device having a novel flow control plate that can be placed in fluid communication with the fluid supply line and with the fluid delivery line. The flow control plate is provided with a plurality of elongated fluidic flow control channels that are in communication with a rate selector member that is rotatably carried by the device housing. Rotation of the rate selector member places a selected one of the flow control channels in communication with the fluid delivery line.

Abstract: A compact fluid dispenser for use in controllably dispensing fluid medicaments, such as antibiotics, analgesics, and the like medicinal agents from the reservoir of the device. Uniquely, the dispenser includes a novel bellows-type reservoir and vial fill means for filling the bellows-type reservoir with the medicament to be dispensed. The dispenser also includes a novel stored energy source in the form of a constant force spring which controllably urges the medicinal fluid from the device reservoir. Additionally, the apparatus of the invention includes a novel adjustable flow rate control assembly that is disposed intermediate the fluid reservoir outlet and the outlet port of the device for precisely controlling the rate of fluid flow from the outlet port toward the patient.
