For cooling damaged areas of biotissue in order to achieve a rapid analgesic effect, a procedure for applying a thin film to the skin, boiling at a temperature of T0 = 273238 K of a gas mixture, is widely used. This temperature is achieved when using a cooling spray. Experimental data on the temperature distribution on the cooled surface when throttling a propane/butane/R123 mixture from a nozzle with a diameter of 0.5 mm to the temperature level Т0 = 240; 263; 270 К, used for physiotherapy purposes, are presented. A comparison of the efficiency of cooling the skin using a cryopresponder and using ice was also made. It is shown that cooling with a cooling spray is more efficient.
