    Abstract: A pressure sensing chamber having a tubing extension with a reduced diameter portion extending through the chamber. The tubing contains a plurality of ports so as to allow the purging of air from the chamber, but the ports are sized so that bubbles entering the tubing cannot easily flow into the chamber. The reduced diameter portion creates a pressure differential between the holes. This differential pressure creates flow through the chamber under high liquid flow and turbulent liquid flow events.

    Abstract: A phacoemulsification fluidics system for irrigating and aspirating a surgical site includes a sterile solution reservoir, an irrigation path configured to extend from the sterile solution reservoir to the surgical site, and an aspiration path configured to extend from the surgical site. The system also includes a single flow control pump head associated with both the irrigation path and the aspiration path. The flow control pump head is arranged within the system to simultaneously pressurize the irrigation path in a manner that drives the irrigation fluid to the surgical site and pressurize the aspiration path in a manner that vacuums waste fluid from the surgical site.
