Abstract
Irrigation system and method for delivering a selected one of multiple liquid solutions to a treatment site include a plurality of solution reservoirs, each including a quantity of a respective liquid solution, a handpiece, a selector valve for fluidly coupling the handpiece to a selected one of the liquid solutions and a pump for causing a selected one of the liquid solutions to flow to the handpiece for delivery to the treatment site. Each of the liquid solutions may have a color which is distinguishable from the color of the other liquid solutions and the tubing to the handpiece is transparent so that the color of a liquid solution flowing through the tube is visible during treatment thereby enabling the identity of the particular solution being used to be quickly verified during treatment. The irrigation system is preferably a closed system with the pump as well as a heater for heating the liquid solution being situated outside of the flow path of the liquid solution. A solution reservoir for use in such an irrigating system is also disclosed.
