Definitions

  • Magnetic field device for stimulation and / or support of body functions
  • the invention relates to a magnetic field device for stimulating and / or supporting body functions.
  • Magnetic field devices are generally known and are manufactured, for example, by mbs syste Arno Fichtner, DE. These magnetic field devices use a one-way rectified sinusoidal signal and a phase control to modulate the intensity of each half-wave. When using a toroid with a winding, a magnetic field with a peak value of approx. 90 gauss is obtained.
  • Magnetic field devices are also known, for example, from WO 92/19317. With these magnetic field devices, a square wave signal is used to generate the magnetic field. A toroid with six windings and an air gap serves as the coil. The peak value of the magnetic field the devices manufactured by the applicant of this application do not exceed the value of 20 gauss.
  • the invention is based on the knowledge that the different treatment successes can be attributed to an intensity setting of the magnetic field which is not adapted to the respective patient.
  • the invention has for its object a magnetic field device for stimulation and / or support of body functions, such as the healing of broken bones, with a current-carrying coil, which is designed so that the body part to be treated or stimulated is that of the coil generated magnetic field is exposed, and a power supply unit, which supplies the current flowing through the coil, and which has a power transformer and at least one switching element, which performs a so-called phase cut of at least one half-wave to control the current flowing through the coil, such that an even treatment success is achieved.
  • An inventive solution to this problem is specified in claim 1. Developments of the invention are the subject of claims two following.
  • a control unit is therefore provided according to the invention, which periodically switches the at least one switching element between at least two power levels.
  • at least two power levels which preferably takes place within a period of a few seconds and in particular one second, each patient is treated with a magnetic field intensity that is optimally suitable for him - at least approximately.
  • the treatment times can be significantly reduced compared to conventional devices by switching between at least two power levels according to the invention.
  • the device according to the invention that only one switching element is provided which switches only one half-wave of the sinusoidal current and which in particular also carries out the phase control.
  • This switching element can in particular be a thyristor.
  • the switchover according to the invention between at least two, preferably three or more power stages fen is preferably implemented via an additional pulse packet control, ie in particular a pulse packet control superimposed on the phase gating controller, the pulse packet width likewise preferably being one second or less.
  • the power levels can be below and above 20 Gauss. In particular, at the highest power level, the value 20 gauss, as is realized in a known device, can be clearly exceeded, and reach 90 gauss and more.
  • phase angle can of course also be varied periodically.
  • the mains transformer supplies an output voltage of 24 volts, since the device is then safe to touch.
  • the coil can be a cylindrical coil or a toroidal coil with up to three windings, wherein all designs - as are known from the prior art - are possible for a lying or sitting patient. Of course, it is possible for the patient to be completely enclosed by the coil or only with the corresponding part of the body.
  • electromagnetic waves in the HF to microwave range and in particular in the decimeter range can be emitted, which support the treatment. zen or with which additional treatments can be carried out.
  • the coil that generates the magnetic field can also emit waves in the decimeter range.
  • the device according to the invention can have a transmitter for the electromagnetic waves, which is controlled by the control unit.
  • the voltage or current that is applied to the coil generating the magnetic field is shown as a function of time in a voltage / time diagram (U / t diagram).
  • the device which is not shown in detail can have a basic structure such as the magnetic field devices from mbs System Arno Fichtner, DE.
  • only one switching element namely a thyristor, is provided only one half-wave of the sinusoidal current switches and thereby carries out a phase control.
  • the control unit which controls the switching element that is to say the thyristor in the exemplary embodiment, superimposes a so-called pulse packet control on the phase gating control which is exclusively provided in the known devices.
  • the figure shows various options for pulse packet control.
  • the pulse packet control has a pulse packet width of 250 ms in the so-called “program 1", while it has a pulse packet width of 80 ms in the "program 2 *” and a width of 40 ms in the "program 3 *".
  • the decisive factor for the success of the treatment is not the mean intensity or power integrated over the certain period of time. Rather, it is crucial that the magnetic field periodically has the instantaneous intensity that is at least approximately optimally adapted for the respective patient. Since in the embodiment shown the intensity is switched between at least two or more - in the embodiment shown three - power levels in periods of less than one second, each patient is treated with the optimal power level for at least part of the treatment without the treating doctor would have to make an adjustment or cessation of performance.

Abstract

L'invention concerne un appareil à champ magnétique destiné à la stimulation et/ou à l'assistance des fonctions du corps, par exemple, la guérison de fractures osseuses. Cet appareil comprend une bobine parcourue par le courant et conçue de telle façon que la partie corporelle à traiter ou à stimuler est exposée au champ magnétique produit par la bobine, et une unité d'alimentation en courant qui fournit le courant parcourant la bobine et qui présente un transformateur réseau et au moins un élément de commutation qui réalise une « section phase » au moins d'une demi-onde pour commander le courant parcourant la bobine. L'invention est caractérisée en ce qu'une unité de commande permet de commuter périodiquement le ou les élément(s) de commutation entre au moins deux niveaux de puissance.
