Description

Področje tehnikeThe field of technology

Magnetna živčno mišična stimulacija se uporablja v diagnostične in terapevtske namene ter za namene vračanja prvotne funkcije posameznim organom. Pri magnetni živčno mišični stimulaciji spominjajoče se magnetno polje visokih gostot magnetnega polja povzroča aktiviranje živčnih celic in z njimi povezanih mišičnih celic.Magnetic neuromuscular stimulation is used for diagnostic and therapeutic purposes and for the purpose of restoring the original function to individual organs. In magnetic neuromuscular stimulation, remembering the high-density magnetic field magnetic field causes activation of nerve cells and related muscle cells.

Stanje tehnikeThe state of the art

Naprava za magnetno mišično stimulacijo je sestavljena iz generatorja toka in aplikatorja s tuljavo. Generator toka generira spreminjajoči se električni tok, ki po žicah teče v tuljavo, katera je nameščena znotraj aplikatorja. Spreminjajoč električni tok v tuljavi in v njeni okolici povzroča magnetno polje. Spreminjajoče magnetno polje tuljave povzroča v človeškem telesu električni tok. Električni tok, ki nastane zaradi magnetnega polja, tako kot mnogo bolj znana električna stimulacija povzroča spremembo napetosti na membrani živčnih celic in posledično sproži akcijski potencial senzornih ali motoričnih živčnih celic. Proženje motoričnih živčnih celic povzroča aktivacijo mišic ter s tem odziv perifernega mišičnega sistema. Za dosego tega učinka je mnogo bolj poznana in pogosteje uporabljena električna stimulacija mišic, pri kateri električni tok povzroča aktivacijo živčnih celic. Pri električni stimulaciji električni tok v telo dovedemo prek električno prevodnih elektrod. Elektrode namestimo na kožo, v podkožje ali ob periferni živec, ki ga želimo stimulirati; pri čemer prevladuje namestitev elektrod na kožo. Elektrode so na kožo lahko pritrjene prek namestitve s potrditvenimi trakovi ali s samolepilnimi elektrodami. Za delovanje električne stimulacije moramo na telo vedno pritrditi vsaj en par elektrod.The magnetic stimulation device consists of a current generator and a coil applicator. A current generator generates a changing electrical current that flows through the wires into a coil that is housed inside the applicator. Changing electrical current in and around the coil produces a magnetic field. The changing magnetic field of the coil causes an electric current in the human body. Electric current generated by a magnetic field, like much more commonly known electrical stimulation, causes a change in voltage at the nerve cell membrane and consequently triggers the action potential of sensory or motor nerve cells. Motor nerve cell triggering causes muscle activation and thus the response of the peripheral muscular system. To achieve this effect, electrical stimulation of the muscles is much more known and more commonly used, in which electrical current causes nerve cell activation. In electrical stimulation, electrical current is brought into the body through electrically conductive electrodes. The electrodes are placed on the skin, subcutaneously, or along the peripheral nerve that we want to stimulate; the placement of electrodes on the skin is predominant. The electrodes can be attached to the skin via mounting with confirmation strips or self-adhesive electrodes. At least one pair of electrodes must always be attached to the body for electrical stimulation to work.

Magnetno polje generira električni tok, ki teče po žici. Magnetno polje običajno generiramo s tuljavo. Tuljavo sestavlja žica, ki je v osrednjem delu enkrat ali večkrat zavita v zaključeno zanko, medtem ko sta oba preostala zaključka žice priklopljena na generator toka. Tako je tuljava z napravo povezana s parom žic. Magnetno polje, ki pri magnetni živčno mišični stimulaciji povzroča električno polje znotraj telesa, je odvisno od velikosti in oblike električnega toka ter oblike tuljave. Naprave za magnetno mišično stimulacijo so opisane v patentih kot so (US6123658) in (US 6123658). Poznamo krožne, metuljaste in trikotne tuljave ter tuljave drugih oblik. Najpogostejše so tuljave krožnih oblik. Stimulaciji z vsemi znanimi vrstami tuljav je skupno to, da se področje stimulacije pod tuljavami ne spreminja.A magnetic field generates electric current that flows through a wire. The magnetic field is usually generated by a coil. The coil consists of a wire which is wound one or more times in a closed loop in the central part, while the two remaining ends of the wire are connected to a current generator. Thus, the coil is connected to the device by a pair of wires. The magnetic field that causes magnetic field stimulation within the body depends on the size and shape of the current and the shape of the coil. Magnetic muscle stimulation devices are described in patents such as (US6123658) and (US 6123658). We know circular, butterfly and triangular coils and coils of other shapes. The most common are circular shaped coils. The stimulation with all known types of coils is common in that the area of stimulation under the coils does not change.

Tehnični problemA technical problem

Pri uporabi magnetne terapije nastane problem pri dolgotrajni terapiji brez vpliva terapevta, saj se magnetno polje aplicira na vedno ista področja. Če želimo spremeniti področje terapije v telesu, moramo premakniti aplikator s tuljavo ali tuljavami.When using magnetic therapy, there is a problem with long-term therapy without the influence of the therapist, since the magnetic field is applied to always the same areas. To change the field of therapy in the body, we need to move the applicator with a coil or coils.

Rešitev tehničnega problemaThe solution to a technical problem

Rešitev tehničnega problema, spreminjanja področja terapije brez posega terapevta, predstavlja aplikator, v katerem je vgrajeno več tuljav, ki so povezane vsaka s svojim med seboj neodvisnim generatorjem toka, ki se nahajajo v napravi za magnetno stimulacijo. V takem sistemu lahko naprava neodvisno določa skozi katere tuljave v aplikatorju v izbranem trenutku teče električni tok. Tako lahko v izbranem trenutku električni tok teče skozi eno, dve, tri, več, vse ali nobeno izmed tuljav, pri čemer naprava po prednastavljenemu programu v naslednjem koraku ta izbor lahko spremeni.The solution to the technical problem of changing the field of therapy without the intervention of the therapist is an applicator that incorporates several coils that are connected to each other by their independent current generators located in the magnetic stimulation device. In such a system, the device can independently determine through which coils in the applicator the electric current flows at the selected moment. Thus, at a given moment, the current can flow through one, two, three, more, all or none of the coils, and the device can change this selection in the next step according to the preset program.

Glavna prednost delovanja je v načinu delovanja naprave, in sicer takrat ko naprava izmenično spreminja izbrano tuljavo, skozi katero teče električni tok. V primeru spreminjanja izbrane naprave v naprej določenih poljubnih časovnih korakih, dobimo spreminjanje področja, kjer v telesu nastane magnetno polje. Posledično se spreminja področje telesa, ki ga s terapijo stimuliramo, kar je enakovredno premikanju aplikatorja po telesu s strani terapevta.The main advantage of operation is in the mode of operation of the device, when the device alternates the selected coil through which the electric current flows. In the case of changing the selected device in predetermined arbitrary time steps, we get to change the area where a magnetic field is generated in the body. As a result, the area of the body that is stimulated by therapy changes, which is equivalent to the movement of the applicator around the body by the therapist.
