Abstract

A rinse system for a medical fluid line. The rinse system may include a pump that is coupled to a reservoir. The pump may pressurize a gas within the reservoir. The pressurized gas also pressurizes a liquid within the reservoir. The rinse system may further have an electronically controlled valve assembly that allows both the liquid and the gas to sequentially flow from the reservoir to rinse the fluid line.

Claims

1. A medical system, comprising:

a phacoemulsification handpiece;

a reservoir adapted to hold both a liquid and a gas;

a pump that can pressurize the gas and the liquid within said reservoir; and

,

a valve assembly that allows the gas and the liquid to flow from said reservoir to said phacoemulsification handpiece.

2. The system of claim 1, further comprising a control circuit that controls said valve assembly.

3. The system of claim 2, wherein said control circuit switches said valve assembly so that the liquid and the gas sequentially flow from said reservoir.

4. The system of claim 2, wherein said control circuit controls said pump.

5. The system of claim 2, further comprising an input panel that is coupled to said control circuit.

6. The system of claim 1, further comprising an outlet line that is in fluid communication with a gas line and a liquid line, said liquid line and said gas line are in fluid communication with said reservoir.

7. The system of claim 6, wherein said valve assembly includes a liquid pinch valve that is coupled to said liquid line and a gas pinch valve that is coupled to said gas line.

8. A medical system, comprising:

a phacoemulsification handpiece;

a reservoir adapted to hold both a liquid and a gas;

a pump that can pressurize the gas and the liquid within said reservoir;

a liquid line in fluid communication with said reservoir;

a gas line in fluid communication with said reservoir;

an outlet line in fluid communication with said gas and liquid lines and said phacoemulsification handpiece; and

,

a valve that is coupled to said liquid line, said gas line and said outlet line and which allows the gas and the liquid to flow from said reservoir through said outlet line and to said phacoemulsification handpiece.

9. The system of claim 8, further comprising a control circuit that controls said valve assembly.

10. The system of claim 9, wherein said control circuit switches said valve assembly so that the liquid and the gas sequentially flow from said reservoir.

11. The system of claim 9, wherein said control circuit controls said pump.

12. The system of claim 9, wherein said valve assembly includes a liquid pinch valve that is coupled to said liquid line and a gas pinch valve that is coupled to said gas line.

13. The system of claim 9, further comprising an input panel that is coupled to said control circuit.
