1. A medical treatment procedure comprising:

  • placing a conduit for flowing a first fluid to or from a living body 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 living body;

    fluidically coupling a bidirectional flow sensor unit to the conduit so that the first fluid and optionally the second fluid are able to flow therethrough in the first and reverse directions, the bidirectional flow sensor unit comprising means for sensing the flow rate and flow direction of the first fluid and optionally the second fluid flowing through the bidirectional flow sensor unit;

    measuring with the sensing means the flow rate of the first fluid as the first fluid flows through the bidirectional flow sensor unit in the first direction, and sensing with the sensing means if the first fluid or the second fluid flows through the bidirectional flow sensor unit in the reverse direction; and

    relaying a signal indicating the occurrence of the first fluid or the second fluid flowing through the bidirectional flow sensor unit in the reverse direction.
