摘要：
A system for a pneumatically-powered vitrectomy machine includes an outputport, a venting valve, a venting manifold, a pressure transducer, and a controller.The output port provides pressurized gas to a vitrectomy probe. The venting valveis located close to the output port. The venting manifold fluidly connects theventing valve to a venting port. The venting port vents pressurized gas from theventing manifold. The pressure transducer is located near the output port. Thepressure transducer is configured to read a pressure of a gas near the output port.The controller is adapted to receive information about the pressure and activatethe venting valve. When the information received from the pressure transducerindicates a fault condition, the controller directs the venting valve to open.
