Intravenous delivery system

摘要

An intravenous delivery system for automatically controlling rate of flow of fluid to a recipient. Desired rate of flow is compared with actual rate of flow to produce error signals which are utilized to cause actual rate of flow to equal the desired rate of flow. The present invention may be used with a conventional gravity drip type IV feed or with an ambulatory system which is independent of gravity. A new quantizer for providing fluid flow independent of gravity is also disclosed.
