摘要:
A high flow rate infusion unit includes a heating unit with opposing, electrically-operated heating plates that contact a heat exchanger to heat infusate flowing therethrough. Pressure infusers on the infusion unit are operable to provide infusate at a high flow rate. A flat, elongate heat exchanger has a laminar fluid flow path receivable between the heating plates to which heat is conducted by contact with the heating plates. A bubble trap and a valve are disposed within the heat exchanger. The bubble trap collects bubbles and vents air from infusate exiting the fluid flow path, and the valve shuts off the flow of infusate if the volume of air in the bubble trap exceeds a predefined limit.
