Abstract
A multiple channel medication infusion system is disclosed which has a plurality of disposable pump cassettes mounted on a single main pump unit, thereby making the system compact and resulting in an economic system. The system has a printer which may be connected to the main pump unit to provide a printed record of system operation. Several modes are accessible to set up and program the system, to monitor actual system performance, and to test the system or display warnings indicating system malfunctions or that new cassettes should be installed.
