Relevance. Modern achievements in physiotherapy and medical electronics allow us to create modern therapeutic and diagnostic devices, including for magnetic therapy, which can improve microcirculation and metabolism in tissues affected by the pathological process. However, magnetic therapy hardware-software complexes with biological feedback in the form of thermal and hemodynamic sensors, which will be maximally adapted to the conditions of activity the physiotherapy department are not developed yet.

Purpose of the study. This study is aimed at creation of a hardware-software complex for the treatment of degenerative-dystrophic and adhesive- cicatricial diseases associated with etiology and localization.

Objectives of the study.

1. Development of a block diagram of a hardware and software complex;

2. Development of the electrical circuit of the magnetic therapy unit;

3. Development of a model of magnetic therapy prototype.

Materials and research methods.

The data of literary sources about modern medical technology for magnetic therapy and magnetic therapy were studied when developing the magnetic therapy hardware-software complexes for the implementation of the new method of magnetic therapy. The object of the study was the equipment for magnetic therapy, and the subject of the study - the components of the magnetic therapy hardware-software complexes.

The results of the study.

A model of magnetic therapy prototype has been developed as a result of the research. The main components of this complex are: a personal computer, a prototype of a magnetic radiation site, a temperature and pulse sensor, a USB interface, a block diagram of the control system. The operation of the magnetotherapeutic complex is set by means of the commands of the control program in the form of pulses, which make it possible to control the mode of exposure.

A prototype of a magnetic emitter operates from a direct current of 25 V. А magnetic field is generated by the output of the device to influence the pathological focus of the body. The program of the personal computer through the USB interface sends a control command to the microcontroller of the control system, which sets the operation mode of the bridge. It is proposed to use software using the methods of spectral analysis of the environment MATLAB.

The required operation mode is fixed on the manual control panel. The developed prototype consists of the following elements (Pic. 1): resistors, diodes, including LEDs, capacitors, transistors, inductors.

Pic. 1. Electrical circuit prototype

The prototype model of the magnetic radiation node of the AIC produced a pulsed magnetic field of low power. It is proposed to use a magnet with a winding resistance of the order of 20 ohms as an electromagnet. Electrolytic capacitors are recommended as capacitors, as they have sufficient capacity necessary for the operation of the constructed unit. Resistors are offered carbonaceous, low-power.

It is proposed to power the device from an autonomous current source with a voltage of 9-12 V, to power the electromagnet.

Components were selected in accordance with the parameters that satisfy the task of creating a magnetic radiation unit assembly (Pic. 2), which include: a three-phase diode rectifier, a filter; bridge circuit; solenoid represented by a 20-ohm copper coil.

Pic. 2. Designed unit block of magnetic radiation

Conclusions

The developed hardware-software complexes for magnetic therapy include continuous feedback from the patient based on the results of his/her temperature and pulse sensors which are being obtained dynamically, thus it is possible to regulate the intensity of magnetic induction acting on the patient during treatment sessions, as well as the dynamics of blood flow in the pathological focus.

In this way, a new type of magnetotherapeutic complex, being developed in the TIU (Tyumen Industrial University) laboratory for treating patients, will increase the effectiveness of treatment and facilitate the work of the medical staff of the physiotherapy departments of polyclinics and hospitals.
