Abstract
Abstract Apparatus for heating blood required for transfusion purposes which enables blood newly drawn from the cold store to be used immediately and without waste. A water tank is provided with a submerged broad based chimneylike convection device having a removable blood-heating coil wound round its outside. An electric heater below the convection device causes heated water to rise up the center and fall around the blood-heating coil. A thermostatic control ensures that the blood is heated to the correct temperature and indicating and other safety devices ensure correct functioning and immediate indication of any failure.
