Abstract
A medical treatment procedure and system that makes use of a bidirectional flow sensor unit to monitor, detect, and control the flow of one or more fluids to and from a patient. The sensor unit measures both flow rate and flow direction of a fluid of a conduit through which a first fluid flows to or from the patient in a first direction, and through which it is possible that the first fluid or a second fluid may flow in a reverse direction through the conduit from or to, respectively, the patient. The sensor unit measures the flow rate of the first fluid as the first fluid flows through the bidirectional flow sensor unit, and senses if the first fluid or the second fluid flows through the bidirectional flow sensor unit in the reverse direction. A signal is relayed to indicate the occurrence of a reverse flow condition.
