Jeder Fühler besteht aus zwei Spulen 11 (Fig. 2) mit gleicher Windungszahl. Ein gemeinsamer Anschluß der beiden Wicklungen jedes Induktionsfühlers 1. ist mit Masse verbunden, während die beiden anderen Anschlüsse der beiden Wicklungen jedes Fühlers mit der entsprechenden Anzahl N von Eingängen eines steuerbaren elektronischen Umschalters 2 verbunden sind, an dessen Steuereingang der Ausgang einer Steuerprogrammeinrichtung 3 angeschlossen ist. Die beiden Ausgänge des elektronischen Umschalters 2 sind mit den Eingängen zweier identischer Niederfrequenzfilter 4 und 5 verbunden, deren Ausgänge an den direkten bzw. invertierenden Eingang eines Differenzialverstärkers 6 angeschlossen sind. Der Ausgang des Differenzialverstärkers 6 ist mit dem Eingang eines Gleichrichters 7 zur Umformung von Wechselspannung in Gleichstrom verbunden. Der Ausgang des Gleichrichters 7 ist mit dem Eingang einer Registriereinrichtung 8 verbunden, die ihrerseits mit einer Blockiereinrichtung 9 verbunden ist. An den Ausgang der Blockiereinrichtung 9 ist ein Magnettherapiegerät 10 angeschlossen.The device according to the invention for measuring the voltage or induction of an alternating magnetic field in the magnet therapy according to FIG. 1 consists of a number N of local Induction sensor 1 ,, l ", ... l., ... 1". Every feeler exists from two coils 11 (Fig. 2) with the same number of turns.

The two outputs of the electronic switch 2 are identical to the inputs of two Low frequency filters 4 and 5 connected, their outputs are connected to the direct or inverting input of a differential amplifier 6. The exit of the differential amplifier 6 is connected to the input of a Rectifier 7 connected for converting alternating voltage into direct current. The output of the rectifier 7 is connected to the input of a registration device 8, which in turn is connected to a blocking device 9 is. A magnet therapy device 10 is connected to the output of the blocking device 9.

Fig. 2 zeigt die Spule 11 der lokalen Induktionsfühler,
deren konusförmige Wicklungen auf eine dielektrische Spule mit quadratischem Querschnitt gewickelt sind.
Fig. 2 shows the coil 11 of the local induction sensor,
whose conical windings are wound on a dielectric coil with a square cross-section.

Die erfindungsgemäße Vorrichtung zum Messen der Induktion eines Wechselspannungs-Magnetfeldes in der Magnettherapie wirkt folgendermaßen:The device according to the invention for measuring induction an alternating voltage magnetic field in magnet therapy acts as follows:

Die lokalen Induktionsfühler 1,, 1„, . ..1„ werden je nach den medizinischen Anforderungen an bestimmten Punkten eines Patienten angeordnet, so daß sie den Körper des Patienten mit der größeren Grundfläche der Spule berühren. Auf diese Weise wird eine hohe Empfindlichkeit der Fühler 1., 1„,
...lvj auf magnetische Signale garantiert, die aus dem Bereich des Patienten kommen, und zwar zum Vergleich mit äußeren
magnetischen Störsignalen bei der Messung schwacher Magnetfelder. Umgekehrt wird beim Messen stärkerer magnetischer Signale die kleinere Grundfläche der Spule der Fühler 1,, I9, .,,1„ dem Patienten zugewandt, und zwar dann, wenn magnetische Signale von einem Organ im menschlichen Körper
bei der Behandlung durch Magnettherapie kontrolliert werden sollen. Die nutzbaren magnetischen Signale induzieren in beide Spulen der lokalen Induktionsfühler 1-, 1~, ...1» Ströme gleicher Größe und in Gegenphase, die der Größe der gemessenen magnetischen Spannung und der Frequenz der magnetischen Signale proportional sind. Die Frequenz der niederfrequenten Filter 4 und 5 wird durch die Wahl der Filterelemente derart festgelegt, daß sie niedriger ist als die Niedrigstfrequenz des nutzbaren magnetischen Signales, das in der Magnettherapie angewendet wird. Hinter den Filtern 4 und 5 werden die Informationssignale von den beiden Eingangen des Differenzialverstärkers 6 für eine höhere als die niedrigste Frequenz frequenzunabhängig.
The local induction sensors 1 ,, 1 ",. ..1 "are arranged depending on the medical requirements at certain points of a patient so that they touch the patient's body with the larger base of the coil. In this way, the sensors 1., 1 ",
... lvj guarantees magnetic signals coming from the patient's area for comparison with external ones
magnetic interference signals when measuring weak magnetic fields. Conversely, when measuring stronger magnetic signals, the smaller base area of the coil of the sensors 1 ,, I 9 ,. ,, 1 “faces the patient, namely when magnetic signals from an organ in the human body
should be controlled during treatment with magnetic therapy. The usable magnetic signals induce currents of the same size and in antiphase in both coils of the local induction sensors 1-, 1 ~, ... 1 », which are proportional to the size of the measured magnetic voltage and the frequency of the magnetic signals. The frequency of the low-frequency filters 4 and 5 is determined by the selection of the filter elements in such a way that it is lower than the lowest frequency of the usable magnetic signal that is used in magnet therapy. After the filters 4 and 5, the information signals from the two inputs of the differential amplifier 6 are frequency-independent for a frequency higher than the lowest.

In der Steuerprogrammeinrichtung 3 wird je nach den medizinischen Anforderungen ein Programm ausgewählt, das mit Hilfe des elektronischen Umschalters 2 die Ausgänge der Induktionsfühler I1, 1„, ...L in einer bestimmten Reihenfolge abtastet und für eine bestimmte Zeit auf die Eingänge der Niederfrequenzfilter 4 und 5 überträgt. Auf diese Weise wird für eine bestimmte Behandlungsdauer bei der Magnettherapie die Intensität der magnetischen Signale an allen N Punkten des Bereichs des Patienten verfolgt. Die verstärkte Spannung am Ausgang des Verstärkers 6 wird zum Gleichrichter 7 übertragen, dessen Ausgangsgleichstrom dem Mittelwert der Spannung des magnetischen Wechselfeldes proportional ist, und zwar in dem Punkt, auf dem sich der entsprechende Fühler befindet, der in diesem Moment wirkt. Das Ausgangssignal vom Gleichrichter 7 wird zum Registriergerät 8 übertragen, das die Blockiereinrichtung 9 einschaltet. Bei einer Erhöhung des zulässigen Wertes der Spannung im magnetischen Wechselfeld an einem der N -Punkte des Bereiches des Patienten oder bei einer Störung während der Ausführung des Programms bei einer therapeutischen Sitzung wird vom Ausgang der Blockiereinrichtung 9 dem Magnettherapiegerät, das das Magnetfeld im Bereich des Patienten erzeugt, ein Blockiersignal zugeführt, durch das das Magnettherapiegerät 10 abgeschaltet wird.In the control program device 3, depending on the medical requirements, a program is selected which, with the help of the electronic switch 2 , scans the outputs of the induction sensors I 1 , 1 ″, ... L in a certain order and for a certain time to the inputs of the low frequency filter 4 and 5 transmits. In this way, the intensity of the magnetic signals at all N points of the patient's area is tracked for a certain duration of treatment in magnetic therapy. The amplified voltage at the output of the amplifier 6 is transmitted to the rectifier 7, the output direct current of which is proportional to the mean value of the voltage of the alternating magnetic field, namely at the point at which the corresponding sensor is located, which is acting at that moment. The output signal from the rectifier 7 is transmitted to the recording device 8, which switches on the blocking device 9. In the event of an increase in the permissible value of the voltage in the alternating magnetic field at one of the N -points of the patient's area or in the event of a disturbance during the execution of the program in a therapeutic session, the output of the blocking device 9 is the magnet therapy device that controls the magnetic field in the patient's area generated, a blocking signal is supplied by which the magnet therapy device 10 is switched off.
