Abstract:
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, the first energy reservoir has a first heating pad and the second energy reservoir has a second heating pad, the first heating pad is capable of generating thermal energy at a different temperature in relation to the second heating pad; 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 heating pad in the respective energy reservoir; and d) each heating pad generates thermal energy to provide a desired temperature to the fluid in each of at least first and second bags which are positioned within the respective at least first and second energy reservoir.
