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.

What is claimed is: 1. A drug-delivery cassette assembly comprising: a) a luer; b) tubing having a drug-receiving end which is fluidly-connectable to a drug vial containing a drug and having a drug-delivery end which is fluidly-connected to the luer; c) a drug-delivery-cassette main board having a

What is claimed is: 1. A drug-delivery cassette assembly comprising: a) a luer; b) tubing having a drug-receiving end which is fluidly-connectable to a drug vial containing a drug and having a drug-delivery end which is fluidly-connected to the luer; c) a drug-delivery-cassette main board having a luer-site base portion having a drip chamber disposed to collect any of the drug which exits the luer when the luer is attached to the luer-site base portion, wherein the luer is attachable to and detachable from the luer-site base portion, and wherein the luer-site base portion has a deflectable luer-site sensor beam which is disposed to be deflected by the luer when the luer is attached to the luer-site base portion and to be undeflected when the luer is detached from the luer-site base portion; and d) a drug-delivery-cassette spike including a drug-vial-seal-perforating spike tip, wherein the spike is attachable to and detachable from the cassette main board. 2. The drug-delivery cassette assembly of claim 1, wherein the cassette main board is attachable to and detachable from a procedure room unit having a luer-in-place optical sensor disposed to sense only one of the deflected luer-site sensor beam and the undeflected luer-site sensor beam. 3. The drug-delivery cassette assembly of claim 2, wherein the procedure room unit controls flow of the drug in the tubing to air purge the tubing and to deliver the drug through the tubing to a patient based at least in part on the luer-in-place optical sensor sensing or not sensing the luer-site sensor beam. 4. The drug-delivery cassette assembly of claim 1, also including a drug-absorbent pad disposed in the drip chamber. 5. The drug-delivery cassette assembly of claim 1, wherein the tubing includes a coiled tube and a flexible tube fluidly-connected together, wherein the flexible tube has a drug-receiving end which is fluidly-connectable to a drug vial containing a drug, wherein the coiled tube has a drug-delivery end which is fluidly-connected to the luer, and wherein the coiled tube is extendible by the user. 6. The drug-delivery cassette assembly of claim 5, wherein the coiled tube includes a plurality of coils and wherein adjacent coils are releasably adhered together. 7. The drug-delivery cassette assembly of claim 5, wherein the coiled tube has a smaller inside diameter than the flexible tube.
