DE2632501A1 - Medical magnet impulse device - is for stimulating nerves in place of acupuncture needles - Google Patents

Abstract

The magnetic impulse unit is for stimulating nerve ends or paths and comprises an electronmagnet (2, 3, 4) consisting of ferromagnetic material pre-treated to achieve large peak field strength in the vicinity of the pole shoes (2) and a coil (4). The form of the pole shoes and the pulses are chosen such that the generated mag net pulses trigger action potentials in the nerve loops of human beings or animals. The instrument can be used in place of needles for acupuncture, reducing risk of infection. Nerves can be easily reached which are inaccessible by prior art techniques.

Magnetic pulse device and its medical application The one presented here The invention relates to a medical therapy device in the sense of neural pathology from SPERANS-ICY, which can be described as a "magneto acupuncture device".

The second phenomenon according to IRINEKE, the Alctipuncture, are known Electro acupuncture according to VOLL and laser acupuncture. Advantage of laser acupuncture is the elimination of possible infections from needles. The disadvantages are limited depth effect and the difficulty of finding hard-to-reach areas (e.g. scars after tonsillectomy) to reach.

Magnetic field therapy according to the German patent application is also known P 22 15 633.8.

The object of the present invention is to transmit stimuli on nerve endings or nerve tracts or on other human or animal Organism to enable existing electrically conductive pathways, their depth effect is not subject to any restrictions, contactless is possible or only slight skin contact requires and also reaches hard-to-reach places without any problems.

The invention is based on the patent application P 22 15 633.8 in the Federal Republic known IvIagnetfeldtherapie, but modified as follows becomes: Instead of long-term irradiation of weak pulse trains only a few very strong magnetic field ~ impulses are briefly and locally limited applied. In the simplest case, a single magnetic field pulse generated by means of a horseshoe-shaped electromagnet, which has suitable pole pieces, on the desired peripheral location or in an accessible body cavity of the organism is used and is so strong that it is in the underlying synapses of the nervous system triggers at least one action potential.

Experience has shown that such a locally set stimulus then has a similar effect like an injection, an acupuncture needle, or a laser beam. By appropriate lFahl the changeable resp.

interchangeably executed Poiscirahc leaves the field of action in determine its area parallel to the skin of the organism and in its depth.

The device will be explained for example with reference to Fig. 1: The suitably shaped pole pieces (2) of the horseshoe-shaped ferromagnetic material (3) are located in the vicinity of the area to be treated of the organism (1) or placed on the skin (e.g. scar, acupuncture point). On the ferromagnetic Material (3) is wound onto the spool (4), which. via the normally open contact (5) the capacitor (6) is connected. The capacitor (6) is across the resistor (7-) charged by a direct voltage source (8), (9), e.g. from the alternating current network (9) via the rectifier (8) # or via a battery (not shown in Fig. 1) Briefly pressing the normally open contact (5) discharges the capacitor (6) pulse-shaped via the coil (4) and its internal resistance (not shown in FIG. 1) with some post-oscillation according to the resonance frequency caused by the inductance the coil (4) and the capacitance of the capacitor (6) as well as to a certain extent is determined by the internal resistance of the coil (4). To avoid sparking the normally open contact (5) is either designed as a vacuum contact or as a semiconductor gate (Thyristor).

When using a thyristor, instead of the DC voltage source (8), (9), the capacitor (6) and the normally open contact (5) a pulse generator with its own Switch-on contact can be used. The impulse is used when the gate is opened (Thyristor).

The decisive factor is the first reloading impulse, which is such a high magnetic one Peak field strength near the pole pieces (2) in the section of the organism to be treated (1) must produce that in that part of the nervous system that is to be treated Section of the organism (1) penetrated, at least one action potential triggered will. The rule is that several synapses are excited simultaneously and synchronously Several action potentials are triggered, which act as a therapeutic stimulus group in the nervous system to get redirected.

It is essential that the pole shoes (2) are suitably designed so that the triggering of such action potentials in the desired area of the organism (1) is achieved will.

The number of turns of the coil (4), the capacity and dielectric strength of the capacitor (6) and the voltage of the DC voltage source (8), (9) are like this to choose that the rise time of the magnetic pulse achieved is small enough is (on the order of a millisecond) and the peak magnetic field strength of the first reloading pulse es - or opening pulse when using a thyristor - is big enough. This must be the number of Amperewindungs, which is determined by the number of turns Coil (4) and the amount of charge on the capacitor (6) is determined in the order of magnitude of 5000 ampere turns, the resistor (7) is to be chosen so that the through the resistor (7) and the capacitor (6) defined charging time constant small is enough to generate new impulses through the working contact with sufficiently small time intervals (5) to be able to trigger. One to ten individual impulses are used for therapeutic purposes at intervals of approx. one to approx. ten seconds each. Possibly is a Repeat this therapy after a few days or weeks.

In order to achieve the desired peak field strength, it is in all Usually it is necessary that the ferromagnetic material (3) is pretreated in a suitable manner as it is described e.g. in German patent application P 26 25 441.1 (Treatment with electric current, magnetic field and infrared radiation).

Fig. 2 shows an example of the shape of the pole shoes (2) for Achieving a relatively large depth effect of the magnetic field lines (lo).

Fig. 3 gives an example of the shape of the pole shoes (2) for the case that only a narrowly delimited area of the organism (1) with magnetic Field lines (io) should be penetrated.

The pulse height can be adapted to the penetration depth so that each At least one action potential is triggered at the desired depth.

Advantages of the invention described are that of suitable shaping the pole shoes (2) possible choice of the area covered in the organism (1) according to its extent parallel to the surface to be treated and perpendicular to it in terms of depth, the omission infections, as they are possible with needles, it is also difficult to reach them easily more accessible places, as the therapeutic effect occurs even if the Pole shoes (2) have a distance of one to two centimeters from the organism (1) and finally the very little effort and the operational reliability of the device. From the standpoint of medical technology, these are significant advances in comparison the previously known local stimulation therapy.

The invention relates to the complete Magnetirnpulsgerät, from Fig. 1 shows one of many possible designs, and in particular the Shaping of the pole shoes (2) in such a way that they are triggered by the normally open contact (5) magnetic impulses with certainty at least one Mctionpotential in the desired Trigger area of the organism (1) and the appropriate choice of magnetic pulse shape with the same goal, which in the example of FIG. 1 by suitable dimensioning the coil (4), the condenser (6) and the DC voltage source (8), (9) reached will.

The invention also relates to the application of what has been described Magnetic pulse device for local stimulation therapy in humans and animals, whereby as suitable areas scars, acupuncture points or other sensitive areas on the body surface or offer them in accessible body cavities (magnetoacupuncture).
