Multiple plate fluid warmer unit
First Claim
1. A parenteral fluid warming system comprising:
- a) at least a first and a second fluid warming bag, every fluid warming bag having an inlet, an outlet, a top surface, a bottom surface, and a fluid path extending between the inlet and the outlet, wherein the coldest fluid path portion is the portion of the fluid path receiving fluid from the inlet, and the warmest fluid path portion is the portion of the fluid path providing fluid to the outlet, wherein the outlet from the first bag directs the fluid into the inlet of the second bag;
b) a warmer device having at least a first energy reservoir and a second energy reservoir;
each energy reservoir corresponds with at least one fluid warming bag, each energy reservoir has at least one heater unit;
c) the top surface and/or the bottom surface of each fluid warming bag, when positioned within a respective energy reservoir, is in thermal proximity to the heater unit in the respective energy reservoir; and
d) each heater unit generates thermal energy to provide a desired temperature to the fluid in the at least first and second bags which are positioned within the respective at least first and second energy reservoir.

Abstract
The present invention is directed to a parenteral fluid warming system. The system has at least first and second fluid warming bags and a warmer device. Each of the at least first and second fluid warming bags have an inlet, an outlet, a top surface, a bottom surface, and a fluid path extending between the inlet and the outlet. In a first embodiment of the present invention, the outlet from the first bag directs the fluid into the inlet of the second bag. In an alternative version of the first embodiment, the first bag and the second bag are a interconnected to each other. The warmer device has at least first and second energy reservoirs that correspond with the number of fluid warming bags. Each energy reservoir also has at least one heater unit.
