Description

Pulp Mash with Timing

The present invention relates to medical equipment, namely, equipment for diagnostic purposes and magnetotherapy using magnetic fields generated by coils.

The Malachite-OUP apparatus for pulsed complex-modulated electromagnetic therapy (USSR, prospect of Triton company D991), adopted as the closest analogue, is known. The device is intended for the treatment of various diseases due to exposure to a diseased organ with a low-frequency electromagnetic field generated by an inductor. The device includes regulation, control and control devices. The device generates electromagnetic pulses with the following characteristics: the amplitude of magnetic induction in the working area of the inductor-emitter is not more than 15 mT, the pulse repetition rate is 0.03-120 Hz. .Pulses are complexly modulated, their duration is not specified. The relatively small magnitude of the magnetic induction amplitude (15 mT), a very wide range of pulse repetition rates (0.03-12.0 Hz), and the absence of a rigorous justification for the pulse duration limits the range of diseases in which the use of this apparatus is advisable.

The proposed magnetic pulse stimulator is designed to increase the effectiveness of electromagnetic therapy and expand its field of application.

The technical result is achieved by the fact that in the known device the inductor is configured to generate a magnetic flux in the center of the inductor of 0.5-3.0 T, and the timer and time delay controller are configured to provide a pulse repetition rate of 0, E-1.0 Hz and pulse duration

Mzobretes is explained by h-vision, which shows the basic scheme of the proposed magnetic pulse stimulator. The stimulator (phLL) consists of a power switch I, a thyristor switch, a step-up transformer 3, a rectifier 4, a storage capacitor 5, ind; ctor b, a thyristor 7, a circuit for comparing and generating a triggering pulse 3, a voltage regulator 9, a timer 10, a time delay regulator II, start button 1.

The stimulator works as follows. When the main switch I is turned on, the mains voltage is supplied to the thyristor switch, as well as to the power of other circuits (power circuits are not shown in the diagram). The time delay is set by the shutter speed control II.

start button IE timer starts counting and turns on tiris

the key switch E, through which the mains voltage is supplied to the primary winding of the boost relay 3. From the secondary winding of transformer 3, voltage is supplied to rectifier 4 "The rectified voltage is supplied to storage capacitor 5 and it. The same voltage is applied to the comparison circuit and, having formed, I start; -1 its pulse 8, the threshold of which is set by the voltage regulator 9. When the voltage on the storage capacitor 5 of a specified value is reached, the comparison circuit and the formation of the triggering pulse 8 gives a pulse to thyristor 7, which it turns on and passes the discharge current of the capacitor 5 to ind b, as a result of which a pulsed magnetic crawl is created, which acts on the nerve pathways and tissues of the body, causing a medical or diagnostic cal effect.

After the discharge of the capacitor 5, the thyristor 7 closes and the charge of the capacitor 5 starts again. The cycle is repeated until the end of the time delay when the timer U turns off the thyristor switch 2

And the device returns to its original state until the next press of the start button 12.

The excellent implementation of the device with the indicated characteristics / does not need special confirmation, since the change in the magnetic flux of the inductor, the pulse repetition rate, and the pulse duration are achieved by the same means as in the close analogue. Applicants created a prototype stimulator.

At the same time, the use of a more powerful induced magnetic field in the proposed device in the optimal range of pulse repetition frequencies and when theoretically justified by the applicants and verified experimentally by the optimal pulse duration (200-50 μs) provides stimulation of the brain and spinal cord, deep peripheral nerves, not available with others methods of stimulation. This, in turn, significantly expands the possibilities of the patient / facilitator in the fields of neuropathology, epileptology, pneumology, pediatrics, ophthalmology, traumatology and orthopedics, and others.

The applicants have reviews of certain reputable clinics and institutes in Russia, confirming on the basis of clinical trials of the device its high diagnostic and therapeutic applications.
