Apparatus for thawing and warming fluids for intravenous administration utilizing heater air recirculation

Device for thawing and warming solutions and biological fluids contained in sealed bags and intended for perfusions or intravenous administration said device comprising in combination:

• cabinet means;
• tray means mounted on and forming the top of said cabinet;
• air intake channel means around said tray and communicating with the interior of said cabinet;
• a plurality of spaced apart apertures arranged around the periphery of the tray means in said air intake channel means and communicating through said air intake channel means with the interior of said cabinet;
• air filter means mounted in said cabinet in such manner that substantially all of the air flowing into the cabinet from the said air intake channel means flows therethrough;
• air impeller means for drawing said air through said filter means and impelling the filtered air;
• air heating means disposed in the path of the impelled air;
• temperature sensing means disposed downstream of the said heating means;
• plenum means for receiving and directing the flow of air;
• air outlet means in said plenum disposed above said tray in such manner so as to direct the flow of air downwardly onto said tray and through said plurality of spaced apart apertures in said air intake channel and recirculation;
• controller means responsive to said temperature sensing means for operating said air impeller means and heating means in such a manner as to maintain a predetermined temperature for the circulating air.
