Abstract

FIELD: medicine; physiotherapy.

SUBSTANCE: group of inventions can be used to correct human sleep parameters. Near a sleeping person, short pulses of an electric field of a rectangular shape are generated with a duty cycle of less than 5% and a duration of 20 ms to 1,000 ms inclusive.

Description

The field of technology to which the invention belongs

The present invention can be used to reduce a person's average sleep latency, improve sleep continuity, increase the amount of non-REM sleep, and make it easier to wake up.

State of the art

PEMF (pulsed electromagnetic field) technology is widely used around the world for therapeutic purposes, including for the implementation of a normalizing effect on human sleep.

Most of the inventions based on PEMF technology use rectangular current pulses fed to an inductor that forms a pulsed magnetic field [USA 8808159, 08/19/2014, Germany, application 102004002218, 08/18/2005, Russian patent 2170109, 07/10/2001]. Sinusoidal pulses are practically not used at all due to their proven low efficiency, however, if the normalizing effect were precisely the magnetic component of the field, then the shape of the pulse would not be significant. This statement is also confirmed by the fact that PEMF technology exhibits extremely poor efficiency in normalizing sleep if it is implemented using sinusoidal pulses, where the change in the magnetic field occurs “slowly”. Separately, it is worth noting that a constant magnetic field acts only on moving charged particles, and an alternating magnetic field - on static ones. Since we are talking about a specific biological effect, it is obvious that charged particles in a bound state (as part of molecules or molecular groups) with a small number of degrees of freedom and an amplitude of motion predominate in a biological organism.

Thus, the problem solved when creating the present invention is to abandon the magnetic component of the pulses, namely, from that part of the pulse when a constant magnetic field is formed (the “plateau” of the pulse, when a constant current flows through the inductor) while maintaining the overall the effectiveness of the method, while the technical result achieved in solving such a problem is to increase the effect of normalizing sleep at all its stages while eliminating the discomfort that people who are sensitive to magnetic fields experience during a long stay near a source of a pulsed magnetic field.

To achieve the set result, a method for correcting human sleep parameters is proposed, which consists in the following:

- generate short ("spike") electric field pulses with a duration of at least 20 ms, preferably from at least 20 to no more than 1000 ms;

- use emerging impulses near a sleeping person, at least one of the following algorithms (successively or any/any to choose from based on needs):

- to improve the continuity of sleep, measured by the number of transitions from the second stage of sleep to the first and to the state of wakefulness;

- to reduce the average sleep latency by gradually changing the duration of impulses during the first 20-30 minutes of sleep;

- to simplify awakening by gradually changing the duration of impulses over the last 30-60 minutes during sleep to increase the amount of non-REM sleep in the second and third stages.

Pulses can be generated through the occurrence of electromagnetic induction, which occurs, in particular, due to the rate of change in the magnitude of the magnetic field generated by the source of the magnetic field, which is used as a flat bifilar inductor, and the rate of change in the magnitude of the magnetic field is regulated by the steepness of the leading edge of the electric pulses supplied per coil, while these pulses have a rectangular shape with a duty cycle of less than 5%.

To achieve the set result, a system for correcting human sleep parameters is proposed for implementing the above method, containing a block for generating short ("spike") electric field pulses; a memory and control unit for said pulse shaping unit; a time control unit that serves to synchronize the generated "spike" pulses with periods of falling asleep, deep sleep and / or awakening.

In the claimed system, the generation unit generates short ("spike") pulses by means of electromagnetic induction and is configured to change the magnitude of the amplitude of short ("spike") pulses by means of the steepness and amplitude of the leading edge of the electrical pulses supplied to the shaper of a time-varying magnetic field; Said time-varying magnetic field shaper can be made in the form of a flat bifilar inductor, which is configured to receive an amplified electrical signal with given parameters of pulse duration, having a rectangular shape with a duty cycle of less than 5%, and said electrical signal with given parameters of duration and duty cycle is formed by the converter. In addition, the mentioned algorithms are stored in the memory block synchronized with the mentioned time control block to coincide in time the formation of "spike" electric field pulses of a certain duration with periods of falling asleep, deep sleep and awakening of a person, including the mentioned control algorithms can be transferred to said memory unit via a mobile application via said Bluetooth module, or from a remote server via said Wi-Fi module.

The capabilities of the claimed system also include such options as self-determination by a person in need of adjustment of sleep parameters, the magnitude of the effect of electromagnetic induction (the power of "spike" pulses of the electric field) by choosing the distance to the mentioned shaper of the time-varying magnetic field, or by controlling the amplitude and steepness leading edge of electrical pulses supplied to said shaper. In addition, a person who needs to adjust sleep parameters can independently choose an algorithm that allows either to adjust all of the mentioned sleep parameters, or any of the mentioned sleep parameters separately.

The possibility of achieving the desired result in the claimed group of inventions is due to the possibility of using a change in the magnitude of the magnetic field that occurs at the leading edge of the pulse, when the current on the inductor changes abruptly, which generates a short (“spike”) electric field pulse in the surrounding space in all nearby closed conductive circuits due to the EMF phenomenon, which, in turn, makes it possible to reduce the duty cycle of the pulse down to 1%, i.e. in fact, to abandon the constant component of the magnetic field, while the efficiency of the result is ensured by the steepness of the leading edge of the electric pulse applied to the inductor, on which the rate of change of the magnetic field depends.

Additional advantages when using the claimed group of inventions are provided by using rectangular electrical pulses with a duty cycle of less than 5%, which allow you to "cut off" the component of the constant magnetic field (because it is formed only when a direct current flows through the coil), leaving only "useful" "spike" impulses of the electric field.

Detailed description of embodiments

The claimed method can be implemented using the system, the scheme of which is shown in Fig. 1.

A system capable of correcting human sleep parameters contains a memory block or "memory" 1, a time control unit or "clock" 2, a converter 3 capable of reading from the control algorithm 8 the parameters (duration and duty cycle) of the signal entering the amplifier 11, from where the amplified the signal is sent to the block for generating short (“spike”) electric field pulses or the shaper of the time-varying magnetic field 6. The control algorithm is recorded and stored in the memory block 1 or transmitted to it via the Bluetooth module 4 via the mobile application 9 or Wi-Fi- module 5 from a remote server 10. The signal duration parameters are changed by combining the start and end times of the control algorithm with the internal clock of block 2. The control unit for the steepness and amplitude of electrical impulses 7 can be adjusted so that optimal parameters of “spike” are formed in the area of a sleeping person. » electric field impulses.

The presented algorithms are either delivered to memory 1 via a remote server 10 via Wi-Fi 5, or downloaded from a mobile application 9 via a Bluetooth module 4, or are selected from those already in memory 1. Algorithm 8 begins to control the parameter of the duration of the electrical signal supplied from the transducer 3 to the amplifier 11. The shape of the electrical signal pulses is adjusted by the control unit for the steepness and amplitude of the pulses 7, which is initially configured by the user to suit the characteristics of his own body. The corrected electrical signal is fed to the shaper of the time-varying magnetic field 6, and the shaper itself is placed near the sleeping person, the distance to which depends on the settings of the control unit for the steepness and amplitude of electrical impulses 7, and is determined by the user himself based on the characteristics of his body.

During the onset of the leading edge of the electrical signal pulse, according to Faraday's law, an electromotive force arises. Its value can be represented in vector form:

Derivative of magnetic induction field is maximum at the maximum steepness of the leading edge of the pulse. Moreover, for the amount affects not only and not how much the magnitude of the magnetic field induction , and the time period , for which it is changed.

This is clearly seen if an auxiliary inductor with an electrical signal amplifier connected to its outputs is placed next to the shaper of the time-varying magnetic field 6. The time-varying magnetic field will generate an EMF and current excitation in the auxiliary coil through the phenomenon of electromagnetic induction ("spike-like" electrical impulses), as shown in Fig. 2.

A specific example of the implementation of the system in order to reduce the average sleep latency of a person is a "step" change in the frequency of "spike" electric field pulses near a sleeping person, as indicated in Table 1, which presents an algorithm for changing the frequency of "spike" electric field impulses near a sleeping person, serving to correct (reduce) the parameter of the average sleep latency of a person.
