Dual source parenteral infusion apparatus
First Claim
1. A parenteral infusion apparatus for delivering parenteral solutions from two sources comprising a first drip chamber with a primary flow sensor means associated therewith for detecting liquid flow rate through the primary drip chamber, a supplemental solution drip chamber with supplemental solution flow sensor means associated therewith for detecting liquid flow rate through the supplemental solution drip chamber, the outlet of the supplemental solution drip chamber being connected with the primary drip chamber inlet by conduit means having a shut-off control system means associated therewith for terminating supplemental solution flow through the conduit when the measured flow detected in the supplemental solution drip chamber is less than the flow detected in the primary drip chamber.
