A pumping system for positive displacement, volumetric liquid control includes a pump having a pumping chamber with a pumping chamber inlet and a pumping chamber outlet. The pumping system further includes a liquid supply inlet for receiving liquid from a liquid supply, and an detector for detecting air in liquid flowing through the liquid path. A liquid valve actuator regulates liquid flow through the liquid supply inlet and a second valve actuator regulates liquid flow through the pumping system outlet. A controller is responsive to an output from the detector to control the pump, the first valve actuator and the second valve actuator such that liquid is directed through the liquid supply inlet and the pumping system outlet during an initial priming sequence until the quantity of air in liquid at the pumping system outlet corresponds to a predetermined value.

Automated drug infusion system with autopriming

A drug identification and security apparatus usable in conjunction with an electronic drug delivery system having at least one drug channel therein, the apparatus providing a first interlock mechanism between a locking member of the apparatus and the drug delivery system to lock the upper and lower doors of the drug channel and to disengage the drug delivery system and prevent removal of a drug container/cassette assembly when the locking member is in a locked position. A second interlock mechanism is interposed between a bar code reading device usable with the drug delivery apparatus and a sensor provided on the drug delivery system, the sensor assuring the placement of a cassette assembly in a drug channel with a scanner activating a switch to enable the scanner to read identifying indicia provided on a drug container of a cassette assembly installed in the drug channel, and both cassette sensor and scanner switch must be activated to enable a scan of a drug container installed in the drug channel, to enable the drug delivery system to deliver the drug in the container through the drug channel to the patient receiving a drug dosage in a controlled amount and at a controlled delivery rate.
