Abstract

A DEVICE FOR STIMULING A HUMAN NERVO SYSTEM WITH A PULSED MAGNETIC FIELD containing a switching power supply, a pulse forming unit, a control unit and an induction coil, characterized in that an ignitron is additionally introduced into the pulse forming unit.

Description

The utility model relates to the field of medical technology and can be used in medicine as a diagnostic device for determining the speed of failure and nerve impulse of DLR by motor fibers of the central and peripheral nervous system of the human body.

When stimulated by a pulsed magnetic field of excess tension of the motor cortex of the cerebral cortex, an action potential is excited in them, which leads to the alpha motor neuron of the spinal cord and then extends to the muscles along the peripheral nervem, where it is recorded as a muscular response. By the time the pulse travels, one can also judge the state of a particular section of the motor paths, it is important for tumor roaesses of the brain and spinal cord, demineralized diseases of the j-nervous system, injuries of the nervous system, and other pathologies.

A well-known technical solution used in the device Hegstifr-200 firm Novometn sz Inc. (Der Nervenarrt, 1988, Part 9, p.5S4-513) and in the HES-1B device of Cadwell (Electroencefalography and clinical Neuropbvsiology, 19SS, 70, p.524-533), which have an identical set of UZLOB in non-working sestognia: induction coil 5 Ј-s h pctenia, electric pulse generation, control unit.

The lack of electrical safety of the device described above (the cases of electric shock to a patient are known), the limited diegostatic capabilities of the device in case of suiclinic and severe forms of diseases, insufficient accuracy of the study of the device in pediatrics.

The closest in technical essence -. the claimed one, selected as a prototype - Groysgvo IE5 -, which has a switching power supply, pulse forming unit, control circuit and induction coil (Ele-it oence-falography and clinical Neurophysiology, 19SS, 70, p, 5Z4-527 l.

Selected - “Ami prototype has the following and ostetkamig

1. The low electrical safety of the device can - lead to injuries 5 c of the patient and medical personnel, - Česk. specifically because of the use of a t-diode chain in the pulse forming unit;

2. Limitation of the diagnostic capabilities of the device in case of dusty and subclinical forms of diseases due to the insufficiently high level of magnetic field strength and the large duration of the leading edge of the pulse of the electric field.

4. The low reliability of studies when using the device in a pediatric clinic due to the large size of the induction coil - stimulator.

The objective of the utility model is to obtain information not only about the motor fibers of the peripheral spines, but also about the state of the motor fibers of the brain and spinal cord, from the cerebral cortex to the spinal roots.

The proposed utility model will improve the safety of the patient and medical personnel, increase the accuracy of diagnosis in emergency conditions and in pediatrics, and provide diagnostically relevant and reliable information for severe and subclinical forms of the disease.

The problem is solved in a utility model by the fact that a device for stimulating the human nervous system with a pulsed magnetic field containing a pulsed power supply unit, a pulse forming unit, a control unit and an induction coil is injected with an ignitron into a pulse forming unit.

Figure 1 shows a schematic diagram of the proposed device for stimulating the human nervous system by a pulsed magnetic field. The device contains; control unit - i, switching power supply - 2, pulse forming unit - 3, ignitron - 4, induction coil - 5. In Fig. 2, the difference in the characteristics of the pulsed electric and magnetic fields of the prototype and the proposed utility model is as follows: pulse of the prototype electric field - 1 pulse of the utility model electric field - 2, prototype magnetic field pulse - 3, magnetic field pulse of the utility model - 4. The device works in the following way:

After turning on the mains voltage, the desired charge level of the switching power supply unit (I) is established on the unit (I) (

, which provides the necessary Delhi front impulse. electric field. Ignitron does not have critical current and discharge voltage of the power supply and such; s; If a short circuit occurs, the ignitron is blocked and ensures complete safety of the patient and medical personnel. .From the forming unit, the pulse goes to the induction coil 5), which creates a magnetic field that directly affects the patient’s nervous system. Ignitron can increase the voltage and capacitance of the capacitors of the pulse power supply and thus increase the intensity of the generated magnetic field, while reducing the size of the induction coil. 3- c- improves the accuracy of diagnosis in severe and su clinical forms of diseases and in pediatrics.

Currently, after passing technically; - tests in the Siberian branch of VNIIIMT, the described utility model c is used for neurophysiological studies and the 4th and in the clinical hospital of Novosibirsk. .. / d & / $ fr N
