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.

Disclosed is a drug-delivery cassette for use with a drug delivery device. The cassette includes a main board and a luer site base portion connected to the main board for positioning a luer on the main board. A drip chamber is included on the main board to collect any drug that exits the luer when the luer is attached to the luer site portion. A deflectable sensor beam is positioned to detect the presence or absence of a luer in the luer site base portion. The drug-delivery cassette further includes a drug vial spike attachable to and detachable from the cassette main board that is connected to the luer by way of a drug delivery tube.

Drug delivery cassette

A system and a method for delivering and metering a fixed volume of liquid, such as a liquid sterilant from a container into a vaporization system. The method for the delivering system includes the steps of sensing a requirement for additional liquid sterilant, determining whether the liquid sterilant to be added is acceptable for use, and delivering the liquid sterilant from a container into an accumulator. The method of metering the liquid sterilant into the vaporization system includes creating a vacuum in a chamber connected to the vaporizer and delivering the liquid sterilant into a vaporizer while continually sensing the flow of the delivery. The metering system maintains a slow, controlled flow in order to achieve efficient vaporization of the liquid sterilant and to provide accurate sensing of the gas/liquid interface.
