Claim 0:
1. A disposable unit of a system for heating a fluid, the disposable unit comprising:
a conduit, defining a central opening;
one or more secondary inductors within the conduit;
an inflow tubing connected to the conduit;
a reservoir for containing an infusate fluid;
a vacuum release valve connected to the reservoir; and
a sensor comprising a transmitter and a receiver, the sensor configured to measure a velocity of ultrasound waves from the transmitter to the receiver, the inflow tubing being disposed between the transmitter and the receiver, the sensor configured to detect a presence of air in the inflow tubing along an ultrasound beam path,
wherein each of the one or more secondary inductors is substantially parallel, and
wherein, when pressure in the inflow tubing is lower than atmospheric pressure, the vacuum release valve allows flow of air into the inflow tubing in order to reduce a pressure difference between the inflow tubing and the atmospheric pressure, thereby preventing and/or reducing deformation of the inflow tubing, and detecting a fluid out condition.
