Abstract
An infusion unit includes a heating unit with opposed heating plates. A heat exchanger has a fluid flow path receivable between the heating plates to which heat is conducted by contact with the heating plates. Infusate flowing under pressure through the fluid flow path is heated by conduction from the heating plates through the fluid container. When the flow of infusate is stopped or interrupted, infusate trapped in the heat exchanger is displaced to a reservoir in the heat exchanger. Displacement of the trapped infusate reduces friction between the fluid container and the heating plates, which assists in extraction of the heat exchanger from the heating unit.
