RU100407U1 - INSTALLATION FOR TRANSCRANIAL EXPOSURE TO A ROTATING MAGNETIC FIELD - Google Patents

Abstract

 Installation for the treatment of cerebrovascular pathology, containing a magnetic field inductor in the form of a cap, characterized in that six phase coils are arranged in a circle around the closed magnetic circuit of the installation, forming three phase windings that create a rotating magnetic field, to which a three-phase voltage regulated by a conversion unit is provided in frequency from 5 to 110 Hz and in magnitude from 0 to 12 V, modulated in amplitude and reversed in each operation cycle by the control unit.

Description

The proposed utility model relates to medicine and can be used, for example, in patients with cerebrovascular pathology (cerebrovascular insufficiency, consequences of ischemic stroke), Parkinson's disease, etc.

A known installation for treatment with a vortex magnetic field according to the patent of the Russian Federation No. 2063254 of 07/10/96, containing a multiphase frequency converter, an inductor covering the working cavity with a rotating seat for a patient placed therein. The inductor in it is made in the form of a series of detachable blocks, each of which includes an annular core with a multiphase winding, and the blocks are enclosed in dielectric housings, and the electric drive to the seat is equipped with a phase-shifting device.

Also known is a device for treatment with a vortex magnetic field according to the patent of the Russian Federation 2353406 dated 04/27/2009, comprising a multi-section cylindrical inductor enclosed in a dielectric housing connected to a multiphase frequency converter with a control unit, between which there are gaps between adjacent sections, and a drive made with the possibility of movement a patient with a cycle different from the cycle of changing the field strength of the inductor. The unit is equipped with a movable carriage.

In both installations, a vortex magnetic field is used as a treatment factor, the intensity of which cyclically changes from zero to maximum and then back to zero, affecting the entire patient's body. Installations are intended for the treatment of malignant neoplasms. During the long-term operation of the units, their high efficiency for the treatment of other diseases, in particular cerebrovascular pathology, was proved. Under the influence of the general magnetic effect, an improvement in cerebral hemodynamics is noted, namely, an increase in the pulse blood supply to the cerebral arteries, a decrease in their tone, etc. It is also proved that the applied magnetic fields (magnetic field strength - up to 6 mT, rotation speed - 6000 rpm) have a vasodilating, antispasmodic, anti-inflammatory, decongestant, immunostimulating and sedative effect.

The disadvantages of the installations are: high metal consumption, large weight and size indicators, the mandatory use of a three-phase power source for operation, the impossibility of changing the rotation frequency and magnetic field strength, the absence of a reverse direction of rotation of the magnetic field.

Currently, for low-frequency magnetotherapy, use:

Magnet-MedTeko, Alimp-1, Polimag-01, BTL-5000, Intramag, Almag, KAP-MT / 8- “Multimag”. In all of these devices, a pulsed or traveling magnetic field is used as a treatment factor.

For the closest analogue, the prefix "Headband" to the devices "AMO-ATOS" (Registration Certificate No. 29/10071001/3132 - 02 of March 12, 2002) and "AMUS-01-INTRAMAG" for transcranial magnetotherapy was adopted. The prefix "Headband" is made in the form of a "helmet" containing a paired emitter of a traveling magnetic field, consisting of two parts of a prismatic shape. The prisms of the emitter are interconnected by a removable elastic arcuate bracket. On the patient’s head, the emitters are fixed using horizontal and vertical fixation belts.

The working surface of each prism, facing, during the procedure, to the temporal lobes of the skull, has a cylindrical surface with a radius close to the average radius of the skull.

In each of the prism consoles, there are three solenoids. The prefix is connected with a cable to any of the free “OUTPUT-1” connectors of the AMO-ATOS or AMUS-01-INTRAMAG devices.

During operation, the solenoids of the prismatic emitters are switched on alternately with the frequency set by the apparatus, this allows you to organize the movement of the magnetic field along each emitter with a penetration depth of 60-90 mm.

Both prismatic emitters of the console have the ability to change their orientation relative to the head and can be used both together and separately from each other.

Disadvantages: insufficient efficiency due to the uneven effect of the magnetic field on all parts of the brain, the inability to generate a rotating magnetic field.

Tasks: increasing the therapeutic effect due to the use of a rotating magnetic field as a therapeutic factor, which is evenly distributed and affects all brain structures.

The essence of the proposed utility model is an installation in which six phase coils are located in a circular magnetic circuit in a circle, forming three phase windings that create a rotating magnetic field, to which a three-phase voltage regulated from 5 to 110 Hz from 0 to 12 is supplied through the conversion unit B, modulated in amplitude and reversed in each operation cycle by the control unit.

The technical result of the utility model is to reduce the time and improve treatment results through the use of a rotating and reversible, amplitude-modulated magnetic field that affects all brain structures, low cost of the apparatus, ease of use, reliability of medical and social rehabilitation.

For a better understanding, the utility model diagram is depicted in figure 1, where 1 is a control unit, 2 is a timer, 3 is a voltage conversion unit, 4 are solenoids (three phase windings) and figure 2, where 5 is a patient’s head, 6 is closed magnetic circuit, on which there are six phase coils - solenoids.

The installation works as follows: the patient can receive treatment while sitting on the couch. For treatment, a holder-rod is used, which allows you to adjust the height of the installation or an adjustable suspension attached to the ceiling. Using the control unit (1), the doctor sets the operation mode of the installation (frequency, magnetic field induction). Using the timer (2) sets the duration of the procedure.

When a single-phase voltage of 220 V is applied, the conversion unit (3) provides the output to the solenoids of phases A, B and C (4) of a three-phase, adjustable from 0 to 12 V in magnitude and from 5 to 110 Hz in voltage frequency.

Using the control unit (1), the voltage supplied to the solenoids (4) is continuously regulated from zero to maximum and back to zero within 2 minutes, which is one cycle.

In the next cycle of operation, the direction of rotation of the magnetic field is reversed.

The procedure ends with a timer (2), which turns off the power to the unit.

Installation example: Patient, 55 years old. Diagnosis:

The consequences of acute cerebrovascular accident. Fifteen procedures were performed at the facility with a magnetic field frequency of 100 Hz and a duration of 30 minutes. Upon admission to treatment, he complained of a headache, neck pain, sleep disturbance. Weakness of the right arm and leg was noted. The gait is unstable when moving. After the procedures, the general condition improved, there were no complaints, sleep normalized, muscle strength in the arm and leg increased. Gait steady, free movements.
