Patent ID: 8894605

Claim:
A system, comprising: a first irrigation fluid source; a first irrigation fluid line connected to the first irrigation fluid source at a first end of the first irrigation fluid line, the first irrigation fluid line having a second end opposite the first end, the second end of the first irrigation fluid line being open so that a first irrigation fluid can be transported from the first irrigation fluid source and out of the second end of the first irrigation line; an aspiration fluid line configured to be in fluid communication with the second end of the first irrigation fluid line; a suction pump to which the aspiration fluid line is connected; a second irrigation fluid source to which a second irrigation fluid line is connected, the second irrigation fluid line being connected to the first irrigation fluid line at a coupling site so that both the first and second irrigation fluid sources are simultaneously in fluid communication with the first irrigation fluid line so that a second irrigation fluid can be supplied into the first irrigation fluid line from the second irrigation fluid line at the same time as the first irrigation fluid can be supplied into the first irrigation fluid line from the first irrigation fluid source, a fluid pressure from the first irrigation fluid source being capable of being built up using the second irrigation fluid source, the fluid pressure being higher than can be achieved with the first irrigation fluid source alone; a first valve between the first end of the first irrigation fluid line and the coupling site; and a second valve between the second irrigation fluid source and the coupling site, wherein the system is an ophthalmosurgical system.
