Adjustable partial body cryotherapy

Abstract

Based on an analysis of the technical level of equipment that implements cryotherapy, the problem of increasing the accuracy of dosing and, accordingly, accurate and uniform cooling of a biological object was identified, which required research into the issues of its controlled cooling. A software for predicting the result of cryotherapy has been developed and a range of rational parameters for supplying gas to the cabin of the installation has been determined when performing controlled cryotherapy (from 40 to 70 g/sec, from -140 to -160 C). An experimental model of a new type of installation has been developed and created, which allows cryotherapy to be carried out with changes in the main parameters of the equipment operation in a wide range of cooling gas flow temperature from -50 to -160 C, free-flow velocity from 0.1 to 2 m/s, cryotherapy time up to 420 sec. Together with a predicting software, it forms a complex for research and controlled implementation of cryotherapy in a wide range of operating parameters. Algorithms for implementing regulated modes for various biological objects and various purposes of exposure have been developed and recommendations have been developed, which allows for the practical application of the proposed concept.
