Abstract
A tool system for operating an irrigation pump. The pump includes a fixed pump head driven by a pump motor and a removable tube set. A readable memory such as a RFID is integral with the tube set. The tube set memory contains data describing the physical characteristics of the tube set. A control console reads the data in the tube set memory. Based on these data, the control console then regulates the operation of the pump motor so that fluid, when required, is delivered at those flow rates. These data are also used by the control console to regulate priming of the pump so that when the system is initially set up a head of irrigation fluid can be pumped close to the end of the handpiece from which the fluid is to be discharged.
