Patent ID: 8287486

Claim:
An infusion pressure monitoring system for a surgical machine to be operated by a health care provider, comprising: an irrigation path configured to carry an irrigation solution to a surgical site; a fluid sensor configured to detect a fluid parameter in the irrigation path; an input device configured to receive a variable infusion pressure or infusion fluid flow command from the health care provider commanding an irrigation fluid pressure or flow through the irrigation path at a pressure or flow rate corresponding to the command; a controller in communication with the fluid sensor and in communication with the input device, the controller being configured to determine an expected fluid pressure value and to determine a dynamically variable threshold pressure value based upon the variable fluid flow command; a hand piece having a tip and an infusion sleeve, the controller being configured to receive equipment data indicative of the tip and infusion sleeve, wherein the controller is configured to determine the expected fluid pressure value based in part upon the equipment data.
