Метод та система динамічного ультрафіолетового випромінювання для фізіотерапії

Abstract

The dissertation is devoted to the development of the functional capabilities of a dynamic physiotherapy system by determining and monitoring the parameters of ultraviolet exposure to affected skin. An analysis of the existing methods and means of irradiating the skin with ultraviolet radiation has been carried out, and the physiotherapy devices are not in compliance with the necessary medical requirements. The elemental base of emitters in UV physiotherapy devices is analyzed, an alternative to mercury sources, namely UV LEDs with dynamic capabilities of spatial and energy flow modulation, is found. The optical characteristics of the main structural components of the skin, the medical aspects of UV physiotherapy and the mechanisms of the influence of optical radiation on a biological object are considered, which confirmed the need for further research of this scientific problem To solve the problem of local and energy modulation, mathematical modeling was carried out and an irradiation method based on UV LEDs was proposed by choosing the optimal light distribution method, which will allow us to build an automated model of energy distribution of ultraviolet radiation. The analysis of electromagnetic radiation sources that can be used to build a system for physiotherapy, and the use of ultraviolet LEDs with a long service life, non-toxicity, and low inertia, is confirmed. The choice of a mathematical model of the distribution of UV radiation in a biological object for assessing the energy impact and the reflection and absorption coefficients of various skin layers is substantiated. A method of dynamic ultraviolet radiation has been developed, which provides constant monitoring and changing the spatial and energy parameters of the procedure during physiotherapy. A calculation was made of surface irradiation with a size of 0.1-0.1 m by a semiconductor diode array to obtain a uniform spatial-spatial field, which allows a predicted effect on the biological object to achieve a therapeutic effect during physiotherapy. Based on the simulated process of the effect of ultraviolet radiation on a biological object, a model for the interaction of UV radiation with the skin is created to identify criteria for the effectiveness of physiotherapy, based on the determination of changes in the absorbing properties of the components of BO as a result of irradiation. Thus, in the dissertation, the urgent and important scientific and technical problem of expanding the functionality of physiotherapy devices by solving the method and system of dynamic ultraviolet radiation was solved. The results obtained are of great scientific and practical importance in determining therapeutic UV exposure doses in local and general physiotherapy.
