The description of the cooling spray for athletes «Ice wave» (pre-production model) is given. It is developed and produced in the JSC «Vekshinsky Research Institute of Vacuum Technology». Experimental data are obtained on the temperature distribution on the cooled surface at throttling from the nozzle of 0,1; 0,5; 1 mm in diameter of the propane/butane/ R123 mixture to the temperature level ТО= –33; –25; –15, –10 °Сused in sport medicine. Rational cooling period for biotissue cryotherapy is obtained – from 3 to 10 minutes – at rapid cooling to 12 ± 20 °C tо3 mm depth.
Itis establishedthat cold penetrates through the skin and produces positive curing effect due to the enhancing of blood circulation in the damaged area. The description of microcirculation change data at the cooling spray application is given. The total rehabilitation time of athletes who used cooling spray is reduced by 2–3 times.
