The technical result is to increase the therapeutic effect due to electromagnetic stimulation of blood supply to the limbs.

Description

The utility model relates to medicine, namely to medical equipment, in particular, to devices for exposure to a traveling pulsed magnetic field.

The following devices can be referred to analogues: patent for invention No. 2152812 dated 06/08/1998, “Device for exposure to a magnetic field on a human body”, patent for invention No. 2151620 dated 05/02/1999, “Device for exposure to a pulsed traveling magnetic field on an organism ", Patent for utility model No. 52332 dated 03/27/2006," Device for influencing biologically active points. "

Closest to the claimed solution is the device No. 52332 dated 03/27/2006, "Device for influencing biologically active points", taken as a prototype, which contains a sinusoidal oscillation generator, timer, amplitude modulator, power supply, control unit, electronic switch, block of inductors - electromagnets, pulse oscillation sensor. The disadvantage of this device is that it allows you to act only on biologically active points (BAP), through low-power inductors - electromagnets.

A distinctive feature of the proposed device is the presence in each channel of a power amplifier with an adjustable gain and one of two inductors - solenoids, which are part of the device and are designed to affect the arm or leg of the patient.

The technical result of the proposed device is to increase the therapeutic effect due to electromagnetic stimulation of blood supply to the limbs. This is achieved by the fact that the device for influencing the human limbs contains a sinusoidal signal generator (GSS), the output of which is connected to the first input of the amplitude modulator (AM), the second input of which is connected to the first output of the control unit (BU), the input of which is connected to the sensor output (D) a pulse signal, the second output of the control unit and the output of AM is connected through an electronic switch (EC) with power amplifiers (PA) individually

adjustable gains, the outputs of which are connected to the corresponding sections of the inductor - solenoid winding (IS), the output of the power supply unit (PSU) is connected to the timer input (T), the output of which is connected to the power lines of the GSS, AM, control unit, and EC.

The device kit includes two solenoids with dimensions:

a) height - 40 cm; diameter - 20 cm; 5 insulated windings (sections) wound in one direction and in one layer with a copper wire 0 1 mm (winding width - 8 cm);

b) height - 40 cm; diameter - 45 cm; 5 insulated windings wound in one direction and in one layer with a copper wire (1 mm (winding width - 8 cm).

The device is used for physiotherapeutic procedures from 1999 to the present in the Dagestan Republican Orthopedic and Traumatology Center. During 2001-2006, only 137 patients aged 19 to 90 years of both sexes with diseases and injuries of the musculoskeletal system were exposed to electromagnetic effects (Table. No. 1).

Contraindications for use were the tumor process, hypotension, pregnancy, the active form of tuberculosis, cardiovascular insufficiency of the II-III stage, as well as the presence in patients of implanted massive metal structures in the exposure zone.

The treatment course was assigned 10 procedures with different magnitudes of magnetic induction with a duration of each procedure from 10 to 15 minutes daily.

The repeated course was carried out with a three-week break, but no more than 3 courses per six months.

Clinical observations show that the use of electromagnetic therapy in diseases of the musculoskeletal system (arthrosis, lymphostasis, arthralgia, epicondylitis, osteochondrosis, spondylosis, etc.), as well as damage to muscles, tendons, ligaments and bones, significantly reduces the rehabilitation period , reduces pain and improves trophic tissue.

The technical result is to increase the therapeutic effect due to electromagnetic stimulation of blood supply to the limbs.
