Abstract
An apparatus for refrigeration treatment is used in cryomedical treatment for applying gas of extremely low temperature onto an affected portion of a patient. In the flow system of the apparatus, there are a liquefied gas source, a temperature controlled bath and a conduit pipe having a cup at its end to be placed over the affected portion. The bath contains a liquid medium of high specific heat in which are immersed a mixing cylinder and an evaporator which are mutually connected with a plurality of tubes. The liquefied gas supplied from the source to the evaporator is vaporized and flowed through the tubes to the cylinder where the vaporized gas is mixed with a liquefied gas directly supplied from the source at an optimum gas temperature.
