Description

DK 170589 B1DK 170589 B1

Opfindelsen angår et elektrisk feltterapiapparat af den art, der er angivet i indledningen til krav 1.The invention relates to an electric field therapy apparatus of the kind set forth in the preamble of claim 1.

Et elektrisk feltterapiapparat af den nævnte art kendes fra GB-A-2.164.563. Eftersom der i det således kendte 5 apparat kun er to elektroder, skal disse være anbragt med en betydelig indbyrdes afstand for at det felt, som de frembringer, skal kunne påvirke en tilsvarende stor del af kroppen på den person, der skal behandles. Den således nødvendige store elektrodeafstand medfører 10 - dels, at der kræves en relativt høj spænding for at frem bringe den fornødne feltstyrke, dels, at det frembragte felt bliver følsomt over for tilstedeværelsen af f.eks. jordforbundne genstande eller bygningsdele i nærheden af området mellem elektroderne.An electric field therapy apparatus of the kind mentioned is known from GB-A-2,164,563. Since in the apparatus thus known there are only two electrodes, these must be spaced at a considerable distance from each other in order for the field which they produce to be able to affect a correspondingly large part of the body of the person to be treated. The large electrode spacing thus required causes 10 - partly that a relatively high voltage is required to produce the required field strength, and partly that the field produced becomes sensitive to the presence of e.g. grounded objects or building parts in the vicinity of the area between the electrodes.

15 Den relativt høje spænding medfører selvsagt en til svarende forøget risiko for elektrisk stød, medens følsomheden over for genstande eller bygningsdele i nærheden af området mellem elektroderne gør det nødvendigt at anbringe apparatet i stor afstand fra sådanne genstande eller byg-20 ningsdele, dvs. at apparatet kræver meget "udenomsplads".Of course, the relatively high voltage results in a correspondingly increased risk of electric shock, while the sensitivity to objects or building parts in the vicinity of the electrodes makes it necessary to place the apparatus at a great distance from such objects or building parts, ie. that the device requires a lot of "outside space".

Det er opfindelsens formål at anvise udformningen af et apparat af den indledningsvis nævnte art, som ikke er behæftet med de ovenfor omtalte ulemper, og dette formål opnås ved et apparat, som ifølge opfindelsen udviser de 25 træk, der er angivet i den kendetegnende del af krav 1. Ved anvendelse af tre elektroder i stedet for to opnås, at afstanden mellem hver elektrode og den nærmest liggende bliver betydeligt kortere end i det kendte apparat, så at der dels kan anvendes en lavere spænding for den samme feltstyrke, 30 dels er muligt at anbringe apparatet nærmere ved eventuelle ledende genstande eller bygningsdele, idet de frembragte felters følsomhed over for sådanne genstande eller bygningsdele er betydeligt formindsket.SUMMARY OF THE INVENTION It is an object of the invention to provide the design of an apparatus of the kind mentioned above, which does not suffer from the above-mentioned disadvantages, and this object is achieved by an apparatus which according to the invention exhibits the features specified in the characterizing part of the invention. Claim 1. By using three electrodes instead of two, it is achieved that the distance between each electrode and the adjacent one is considerably shorter than in the known apparatus, so that a lower voltage can be used for the same field strength, and partly possible. to position the apparatus closer to any conductive objects or building parts, the sensitivity of the fields produced to such objects or building parts being greatly diminished.

Yderligere udførelsesformer for apparatet ifølge 35 opfindelsen, hvis virkninger - ud over hvad der er indlysende - vil fremgå af den efterfølgende specielle del af nærværende DK 170589 B1 2 beskrivelse, er angivet i krav 2-5.Further embodiments of the apparatus according to the invention, the effects of which - in addition to what is obvious - will become apparent from the following special part of the specification, are set out in claims 2-5.

Opfindelsen skal i det følgende forklares nærmere under henvisning til det på tegningen viste udførelseseksem-The invention will be explained in more detail below with reference to the embodiment shown in the drawing.

pel på et elektrisk feltterapiapparat ifølge opfindelsen.pile on an electric field therapy apparatus according to the invention.

5 Tegningen viser et kredsløb for et elektrisk feltterapiapparat A' ifølge en udførelsesform for opfindelsen * således: - en kommercielt tilgængelig elektrisk energikilde 9, indgangstilslutninger 10 til et apparathus 1 hørende 10 til det elektriske feltterapiapparat, en spændingsforhøj ende transformator 11, der transformerer spændingen fra energikilden 9 til en høj spænding, og strømbegrænsningsmodstande 12.5 The drawing shows a circuit for an electric field therapy apparatus A 'according to an embodiment of the invention * as follows: - a commercially available electric energy source 9, input connections 10 to an electrical housing therapy apparatus 10 belonging to the electric field therapy transformer 11, which transforms the voltage from the power source 9 for a high voltage, and current limiting resistors 12.

Endvidere viser tegningen 15 - høj spændings-udgangstilslutninger 2t-j_, 2t2 og 2t3 for en sekundærspole i apparathuset 1, hvilke tilslutninger er indrettet til at modtage forskellige potentialer, - en højspændingselektrode 4a!, som fra apparathuset 1 påtrykkes et højt elektrisk potentiale, 20 - en elektrisk isolerende del 4b! for elektroden 4a!, idet disse to dele 4a! °9 tilsammen udgør et første elektrisk ledende organ 4D!, en højspændingselektrode 4a2, som fra apparathuset 1 påtrykkes et højt elektrisk potentiale, 25 - en elektrisk isolerende del 4b2 for elektroden 4a2, idet disse to dele 4a3 og 4b2 tilsammen udgør et andet elektrisk ledende organ 4D2, en højspændingselektrode 4a3, som gennem apparathuset 1 er forbundet med jord, 30 - en elektrisk isolerende del 4b3 for elektroden 4a3, idet disse to dele 4a3 og 4b3 tilsammen udgør et tredje elektrisk ledende organ 4D3.Furthermore, the drawing 15 - high voltage output terminals 2t-j_, 2t2 and 2t3 for a secondary coil in the device housing 1 shows which connections are arranged to receive different potentials, - a high voltage electrode 4a!, Which is applied from the device housing 1 to a high electrical potential, 20 - an electrically insulating part 4b! for the electrode 4a!, these two parts 4a! ° 9 together constitutes a first electrically conductive member 4D !, a high voltage electrode 4a2, which is applied from the housing 1 to a high electrical potential, 25 - an electrically insulating part 4b2 of the electrode 4a2, these two parts 4a3 and 4b2 together forming a second electrical conductor means 4D2, a high voltage electrode 4a3 which is connected to ground through the apparatus housing 1, 30 - an electrically insulating part 4b3 of the electrode 4a3, these two parts 4a3 and 4b3 together forming a third electrically conductive means 4D3.

Når nu en højspænding, der er frembragt i den ene ende af sekundærspolen i transformatoren 11, påtrykkes det 35 første elektrisk ledende organ 4D!, der er anbragt i nærheden af hovedet på personen 6, gennem en udgangstilslutning 2t!, DK 170589 Bl 3 og en højspænding, der er frembragt i den anden ende af denne sekundærspole, påtrykkes det andet elektrisk ledende organ 4D2, der skal bringes i berøring med det viste hofteområde på personen 6, dannes et kraftigt elektrisk felt 5 mellem den første og den anden elektrode, så at den øverste halvdel af personen 6 bliver behandlet af dette kraftige elektriske felt.Now, when a high voltage produced at one end of the secondary coil in the transformer 11, the first electrically conductive means 4D!, Placed near the head of the person 6, is applied through an output connection 2t !, DK 170589 B1 and a high voltage generated at the other end of this secondary coil is applied to the second electrically conductive member 4D2, which is to be brought into contact with the illustrated hip area of the person 6, a strong electric field 5 is formed between the first and second electrodes so that that the upper half of the person 6 is treated by this powerful electric field.

En nederste halvdel af personen 6 bliver behandlet af et kraftigt elektrisk felt, der dannes mellem det tredje 10 elektrisk ledende organ 4D3, som gennem udgangstilslutningen 2t3 er forbundet med et mellemliggende punkt på sekundærspolen og bragt i berøring med fodsålerne på personen 6, og ovennævnte andet elektrisk ledende organ 4D2.A lower half of the person 6 is treated by a strong electric field formed between the third electrically conductive member 4D3 which, through the output connection 2t3, is connected to an intermediate point on the secondary coil and brought into contact with the soles of the person 6, and the above mentioned second electrical conductor 4D2.

Ved ifølge opfindelsen at anbringe de respektive 15 elektrisk ledende organer i nærheden af personen, kan denne behandles uden at blive påvirket af eventuelle afstandsforskelle mellem personen og elektrisk ledende genstande, såsom en omgivende struktur. Dersom i det på tegningen viste udstyr ét af de to elektrisk ledende organer 4D2 og 4D3, der står 20 i berøring med personen 6 - i det viste eksempel organet 4D3 - forbindes med jord, bliver det elektriske potentiale af personen 6 lavere end spændingen mellem højspændingsudgangstilslutningerne 2t1 og 2t2 på sekundærspolen i transformatoren 11, og derfor vil et elektrisk stød, som personen 25 måtte opleve, blive reduceret, selv om personen kommer i berøring med den omgivende struktur. Desuden vil det øvrige elektrisk ledende organ 4D2 eller 4D3 stå i berøring med personen 6, men er ikke jordforbundet, og derfor kan personen 6 opleve en passende fornemmelse af tilførslen af elektrisk 30 strøm.By placing the respective electrically conductive means in the vicinity of the person according to the invention, this can be treated without being affected by any distance differences between the person and electrically conductive objects, such as a surrounding structure. If, in the equipment shown in the drawing, one of the two electrically conductive means 4D2 and 4D3, which is in contact with the person 6 - in the example shown the member 4D3 - is connected to ground, the electrical potential of the person 6 becomes lower than the voltage between the high voltage output connections. 2t1 and 2t2 on the secondary coil of the transformer 11, and therefore an electric shock experienced by the person 25 will be reduced even if the person comes into contact with the surrounding structure. In addition, the other electrically conductive means 4D2 or 4D3 will contact the person 6 but are not grounded and therefore the person 6 may experience a suitable sensation of the supply of electrical 30.
