Electric heating device for heating sterilized fluids, such as blood

摘要: A device for heating blood transfusion is disclosed which has two vertically disposed opposed electrical plates engage the opposite faces of a flat bag flexible plastic material delimitating fluid path therethrough width progressively increasing from lower inlet pipe connection to supply an elongated single rectilinear main portion uniform and decreasing toward upper outlet injection means. flow restricting means therein on intermediate level between restrict travel introduced by produce substantially homogeneous all across path. The include heat radiating fins or corrugations reduce thermal inertia as rate changes. electric each plate so distributed that power gradually decreases bottom top plate.
