ABSTRACT:
An apparatus for fluid handling and delivery in a medication infusion system is disclosed. The apparatus generally contains a pulsatile pump in combination with at least an accumulation flow restrictor. The pulsatile pump is economical in electrical consumption by virtue of the use of a spring force pumping action. The accumulator flow restrictor smooths the output from the pulsatile pump so that medication is delivered in a manner compatible with human or animal body needs. As an example, for infusion of medication such as insulin, the medication infusion system can provide an infusion flow profile which mimics that of insulin production in a normal person.
