IV fluid warming system with detection of presence and orientation of an IV fluid heat exchanger

An intravenous (IV) fluid warming system comprising:

• a warming unit with:
• an enclosure having an inlet slot;
• and,
• at least one heating element positioned in the enclosure;
• and,
• an IV fluid heat exchanger comprising;
• a frame receivable in the inlet slot,
• a heat exchanger membrane attached to the frame, the heat exchanger membrane having an internal fluid pathway;
• a fluid inlet port near a first end of the internal fluid pathway;
• a fluid outlet port near a second end of the internal fluid pathway;
• and
• a detector acting between the IV fluid heat exchanger and the warming unit to indicate the orientation of the IV fluid heat exchanger in the warming unit, the detector including a first magnetic element in the warming unit and a second magnetic element in the IV fluid heat exchanger.

An intravenous (IV) fluid warming system comprising:

• a warming unit with an inlet slot;
• an IV fluid heat exchanger receivable in the warming unit inlet slot, the IV fluid heat exchanger having an internal fluid pathway and a fluid inlet port and a fluid outlet port in fluid communication with the internal fluid pathway;
• and
• a detector acting between the warming unit and the IV fluid heat exchanger to sense the presence and orientation of the IV fluid heat exchanger in the warming unit, the detector including a first magnetic element in the warming unit and a second magnetic element in the IV fluid heat exchanger.
