Definitions

  • This invention relates to electro-medicinal apparatus.
  • the area of the electrodes of such apparatus which lead the e ectric current to the tissue of the object treated, are small in comparison to the dimensions of the object treated, and as a consequence the greatest current con-- centration and thus the greatest stimulating effect are resulting next to the electrodes.
  • an upper limit is set to the intensity of current applicable, said limit lying in many cases below the dosage desirable for medicinal reasons. Small children or oversensitive individuals frequently feel unbearable already the mere electrifying action at the places of the skin next to the electrodes, even if it lies very far still below the limit of endurance, so that an electro-therapeutic treatment, even if it were accommodated as much as possible, is impracticable.
  • the present invention represents a successive further development of the electro-medicinal apparatus as described in my copending application Ser. No. 56,889 according to which the currents received from separate sources and supplied by means of separate electrodes are united within the tissue to a predetermined, resulting current field, and has for its object to eliminate any disturbing stimulating effect of the current upon the parts of the skin situated below the electrodes.
  • This invention essentially consists in that the single currents have a frequency, each, lying above the normal stimulating frequency suitable for a permanent excitation, said frequencies being distinguished by a figure of frequency lying within the normal region of frequency suitable for a permanent excitation, so that a resulting current field is brought about inside .the object treated, which releases permanent excitations in the rhythm of the difference of the individual frequencies (beat frequency).
  • excitations consist of pulsating vibrations of the nerves caused directly by electric current at a certain depth of the body, said vibrations resulting for example as to the motor nerves in contractions of the muscles belonging to them.
  • the beat frequency may be varied by hand or automatically.
  • the internal resistance of the separate sources of current is great in comparison to the resistance of the circuits of the electrodes (circuits of treatment).
  • the stimulating effect of the electric current is dependent on the form of the individual impulses, the frequency of the succession of the same, as well as on the intensity of the same.
  • the phenomenon known in the entire physiology of the senses may be mentioned, according to which there results an accommodation or habituation to the irritation, and this in fact the faster and the more completely, the more equal said irritation is with regard to its temporal course.
  • This explains that a series of electric impulses with a constant intensity are registered by the sensitive nerves of the skin the less the larger the duration of the action is.
  • keeping a series of impulses of a constant level is an important means for decreasing the sensitive stimulating effect of said impulses.
  • both oscillators 3 and 6 are swinging at an equal frequency of 3000 cycles, which may for the oscillator 6 be continually set, or varied, between 3000 and 3100 cycles with the aid of the condensers l4 without altering thereby the oscillatory power delivered.
  • both oscillatory circuits 3 and 6, respectively are sufficiently screened.
  • the principally important separation of both circuits be to an inadmissibly great extent diminished by a coupling through the object treated.
  • the electrodes illustrated are applied in such a manner that the motor point of irritation comes to lie in the centre of the arrangement of the electrodes, and the intensity of the partial or component currents of equal frequency supplied by both circuits is so slowly increased in a creeping in manner that neither a sensitive, nor a motor stimulating effect of the current is brought about.
  • Electro-medicinal apparatus comprising two separate generators for producing alternating currents of a frequency between 1000 and 10,000 cycles, but differing as to their frequency by an amount of about 1-100 cycles, pairs of electrodes connected, each, with one of said generators and with the object treated, respectively, for supplying interacting currents producing a maximum permanent stimulating effect upon a nerve of a muscle.
  • Electro-therapy apparatus comp-rising at least two means for producing alternating currents of frequencies between 1000 and 10,000 cycles at the most and practically without a permanent stimulating effect for stimulating the nerves of muscles, a rectifier and a variable resistance in each of said means, a separate electric circuit being connected with each of said means, separate pairs of electrodes for each of said circuits, each of said means being connected with a separate pair of said electrodes, in at least one of said means a condenser and a device, both for regulating the frequency of at least one of said currents to produce, as a modulating frequency, a difference of frequency between the frequencies of said currents of 100 cycles at the most in the range where the currents are superimposing one another.
  • Electro-therapy apparatus as claimed in claim 2, wherein internal resistances are provided in said circuits, said resistances being greater than the resistances of the circuits of treatment between said connected electrodes.
  • Electro-therapy apparatus as claimed in claim 2, comprising an oscillator and an amplifier in each of said means for producing sine wave alternating currents.
  • Electro-therapy apparatus as claimed in claim 4, comprising a variable condenser for producing said modulating frequency, said condenser being in parallel to the oscillatory circuit of the oscillator.
  • Electro-therapy apparatus comprising a supply transformer, two separate circuits, each connected with said transformer, an oscillator and an amplifier for producing sine wave alternating currents of substantially equal frequency being arranged in each of said circuits, a condenser in one of said circuits being adapted to vary the frequency of this circuit for producing a beat frequency of the order of from 1 to 100 cycles per second by superposing the frequencies of both circuits, internal resistances greater than the resistances of the circuits of treatment being provided in said circuits.
