Abstract
The present invention relates to a system for flushing a medical device, comprising a multi-port valve for controlling the delivery of flushing fluids, the multi-port valve connected to a source of pressurised flushing gas; a fluid outlet for coupling flushing fluids to the medical device; and, a gas-driven pump connected to the fluid outlet, wherein, in a first configuration, the multi-port valve couples a flow of gas from the source of pressurised flushing gas to the fluid outlet, and wherein, in a second configuration, the multi-port valve couples a flow of gas from the source of pressurised flushing gas to the gas-driven pump to drive the gas-driven pump thereby to provide a flow of flushing liquid to the fluid outlet.
