Abstract
Apparatus, system and method for providing pressurized infusion of liquids and, more particularly, providing a stable and pressurized flow of fluid to the eye during surgery. Aspiration fluid may be received via an aspiration line at a first peristaltic pump, where aspiration fluid is transferred to a Venturi tank reservoir coupled to a second peristaltic pump. Fluid from a fluid source is provided via a third peristaltic pump to a pressurized infusion tank. A determination is made if the pressure in the pressurized infusion tank is at a predetermined level, where fluid may be transferred from the pressurized infusion tank to an irrigation line when pressure in the pressurized infusion tank is determined to be at the predetermined level. Alternate activation of a plurality of aspiration and irrigation lines are also provided.
