Abstract

Disclosed is a drug delivery infusion pump assembly containing a drug delivery pump, a drug delivery cassette, a pump door, and a housing adapted to receive a drug vial. A drug vial centering mechanism ensures varieties of drug vial sizes are compatible with this device. The drug delivery cassette is capable of being positioned on the drug delivery infusion pump assembly so the drug delivery pump will interface with a drug delivery tube located on the drug delivery cassette.

Claims

1. A drug-delivery infusion pump assembly comprising:

a) a drug-delivery infusion pump housing;

b) a drug-delivery cassette assembly attachable to the infusion pump housing, the drug delivery cassette comprising;

i) a tubing assembly for conveying a drug;

ii) a drug-vial spike attached to a base portion, wherein the base portion is adapted to attach to the drug delivery cassette and to connect to and disconnect from the tubing;

wherein the drug-delivery cassette assembly defines a co-planar area having a recessed portion for accepting the base portion; and

c) a pump-housing door attached to the infusion pump housing, having door-open and door-closed positions, and having drug-vial-aligning fingers which center and align different diameter drug vials when the cassette assembly is attached to the infusion pump housing;

the pump-housing door is in the door-closed position; and

a drug vial is inserted between the drug-vial-aligning fingers for engagement with the spike.

2. The drug-delivery infusion pump assembly of claim 1, wherein the cassette assembly is attachable to, and removable from, the infusion pump housing when the pump-housing door is in the door-open position.

3. The drug-delivery infusion pump assembly of claim 1, also including a drug-delivery peristaltic pump disposed in the infusion pump housing and having pump fingers, wherein the cassette assembly is operatively connectable to the pump fingers when the cassette assembly is attached to the infusion pump housing and the pump-housing door is in the door-open position.

4. The drug-delivery infusion pump assembly of claim 1, wherein the base portion threadedly attaches to and disconnects from the tubing.

5. The drug-delivery infusion pump assembly of claim 1, wherein the recessed portion comprises alignment pins for interfacing with corresponding alignment apertures positioned on the base portion.

6. The drug-delivery infusion pump assembly of claim 1 further comprising a removable cap element adapted for removably enclosing at least a portion of the drug-vial spike.

7. The drug-delivery infusion pump assembly of claim 1 further comprising a sensor for sensing when the drug vial is placed on the drug-vial spike.
