Heat exchanger for high flow rate infusion
First Claim
Patent Images
1. A heat exchanger for heating fluids in a high flow rate infusion system, comprising:
- an inlet and an outlet;
a fluid container with a near and distal ends, two edges, and a laminar flow path in fluid communication with the inlet;
a housing attached to the fluid container at the near end;
a bubble trap in the housing in fluid communication with the laminar flow path; and
a valve in the housing in fluid communication with the bubble trap and the outlet.

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.

18. A combination for heating fluids in a high flow rate infusion system, comprising:
-
a heat exchanger constituted of; an inlet and an outlet; a fluid container with a near and distal ends, two edges, and a laminar flow path in fluid communication with the inlet; a housing attached to the fluid container at the near end; a bubble trap in the housing in fluid communication with the laminar flow path; and a valve in the housing in fluid communication with the bubble trap and the outlet; and
,a pair of opposed heating plates defining space therebetween for slidably receiving the fluid container, the heating plates including; means in the heating plates responsive to pressurized infusate in the laminar flow path for causing input and output manifolds to form in the fluid container; and means in the heating plates for causing the fluid container to be disengaged from the heating plates. - View Dependent Claims (19, 20, 21)
