Abstract:
A system for warming blood or other liquids to body temperature for infusion into a patient comprising:A.) a blood warmer apparatus having a pair of fixedly closely spaced apart heat transfer plates adapted to receive a flat heat exchanging blood warming envelope between said fixedly closely spaced apart heat transfer plates, wherein the gap between said fixedly closely spaced apart heat transfer plates is exposed at two opposite ends forming a wide slot, B.) an inserter for positioning said flat heat exchanging blood warming envelope between said fixedly closely spaced apart heat transfer plates including, 1.) a sheet of semi-rigid material slightly thinner and narrower and longer than said wide slot formed by the gap between said fixedly closely spaced apart heat transfer plates, 2.) means for attaching said sheet of semi-rigid material to said flat heat exchanging envelope along its insertion edge, 3.) means such as perforations for tearing off or otherwise removing all but about 2 inches of said sheet of semi-rigid material after it has been used to insert and position said blood warming envelope, 4.) means such as a hole about 0.25 to 0.38 inch in diameter in the remaining approximately 2 inches of said semi-rigid material for attaching it to a post or other attaching means fixedly mounted appropriately on rear case of said blood warmer apparatus after said semi-rigid material has been used to insert and position said blood warming envelope, whereby a person can easily insert and correctly position said flat heat exchanging blood warming envelope in said blood warming apparatus.
