Abstract
A heat exchanger has a laminar fluid flow path receivable between the heating plates of a high flow rate infusion unit to which heat is conducted by contact with the heating plates. A bubble trap and a valve are integrated with the heat exchanger. The bubble trap collects air from the infusate exiting the laminar flow path, and includes an air vent in contact with the infusate that vents the air from the bubble trap. The valve shuts off the flow of infusate if air is detected in the bubble trap.
