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.

Claims

1. Periodontal irrigating system for delivering one of a plurality of liquid irrigating solutions to a treatment site in an oral cavity, comprising:

a plurality of solution reservoirs, each reservoir including a quantity of a respective liquid irrigating solution substantially sealed within a container;

handpiece means for gripping by an operator and delivering a selected one of said liquid solutions directly to a treatment site;

liquid solution coupling and selector means for fluidly coupling said handpiece means and a selected one of said liquid irrigating solutions of a respective solution reservoir, said liquid solution coupling and selector means including selector valve means having a plurality of inputs, an output, first tubing means for fluidly coupling each of said liquid irrigating solutions and a respective one of said inputs of said selector valve means, and second tubing means for fluidly coupling said output of said selector valve means and said handpiece means; and

pump means for causing a selected one of said liquid irrigating solutions to flow from said reservoir thereof to said handpiece means for delivery to the treatment site, said pump means operatively engaging only said second tubing means and being situated entirely out of the path of said flow of said selected liquid irrigating solution from said reservoir thereof to said handpiece means.

2. A system as recited in claim 1 further including reservoir mounting means comprising storage means having first indicia means for designating respective solution reservoirs stored therein, and wherein said selector valve means have second indicia means associated with said coupling means thereof corresponding to said first indicia means for designating respective solution reservoirs.

3. A system as recited in claim 1 wherein said pump means comprises a peristaltic pump.

4. A system as recited in claim 3 wherein said second tubing means comprises a first part fluidly coupling said output of said selector valve means to an inlet side of said pump and a second part fluidly coupling an outlet side of said pump to said handpiece means.

5. A system as recited in claim 4 wherein said peristaltic pump includes a pump tube comprising a part of said second tubing means, said pump tube having an inlet side fluidly coupled to said first part of said tubing means and an outlet side fluidly coupled to said second part of said tubing means, a rotor including means for engaging and squeezing said pump tube upon rotation thereof, and means for rotating said rotor.

6. Periodontal irrigating system for delivering one of a plurality of liquid irrigating solutions to a treatment site in an oral cavity, comprising:

a plurality of solution reservoirs, each reservoir including a quantity of a respective liquid irrigating solution substantially sealed within a container;
