Drug delivery cassette and a medical effector system
First Claim
1. A drug-delivery infusion pump assembly and drug-delivery cassette assembly combination comprising:
- a) a drug-delivery infusion pump housing;
b) a drug-delivery cassette assembly attachable to the infusion pump housing, having a tubing and a luer combination, and having a drug-delivery-cassette main board including a luer-site base portion, wherein the luer is attachable to and detachable from the luer-site base portion, and a tubing storage portion, wherein the tubing is releasably stored in a coiled state in the tubing storage portion;
c) a pump-housing door attached to the infusion pump housing and having door-open and door-closed positions; and
d) a pump-housing door lock which, when the cassette assembly is attached to the infusion pump housing and the pump-housing door is in the door-closed position, cannot unlock unless the luer is attached to the luer-site base portion.

Abstract
Disclosed is an interface between a drug delivery cassette and a medical effector system. The cassette may be mounted to the medical effector system in such a way that a fluid tube located on the cassette is positioned adjacent to a pump located on the medical effector system. The medical effector system may purge the fluid line of air by activating the pump and forcing fluid through the fluid line until a sensor positioned to monitor the fluid line indicates that fluid and not air is present in the tube. To prevent air purging of the fluid tube when connected to the patient, the medical effector system prohibits air purging unless the drug delivery end portion of the fluid tube is in a designated storage site located on the cassette. This is accomplished with a position sensor at the storage site that monitors the position of the fluid tube.
