Abstract

One or more permanent magnets (4) is arranged about the periphery of a rotary support or impeller (3) driven by the shaft (2) of an electric motor (1). The number of revolutions of the rotary support is constant or periodically or temporarily variable.

Description

object The invention is a device for the production of a pulsating magnetic field in human therapy Magnetic forces are already used in historical periods been used to combat symptoms of illness That concerned at the time mostly tensions of the muscle area but also disorders in the Nervous system. In the past decades are due to electrodynamic Magnetic fields and also in the use of strong permanent magnets new knowledge has been gained, especially after appropriate measurement methods and devices have been developed with adjustable dosage. Take this the so-called magnetic resonance therapy a special place. After it has been proven to what extent magnetic waves on the human organism in disorders of health-alleviating or achieve healing effect is the application in large width increased sharply. For the use for self-help also handy devices have been developed which produce battery-powered magnetic fields whose Pulsation frequencies are adjustable.

The Producing the required magnetic forces in their way for the required Operation requires electronic effort. for the electrodynamic Magnetic field generation. The necessities magnetic field strengths with at least 5-8 mT (50-80 Gauss) require one high-quality equipment in particular, if different Frequencies appear necessary. As a result of the physical fact that the magnetic field strength of Place their origin in about quadratic decrease must be reduced electronically constructed generators for a depth effect with approx. 6 mT at 6 cm distance at least 70-90 mT be provided. Such devices are expensive and expensive.

object The task is the execution of a device without Use of electronic means, on the one hand with increased magnetic field strength, on the other hand with low effort.

In execution the task is done using a permanent magnetic field which is mechanically rotated.

For the practical execution gets on a slow-runner in the form of e.g. an instrument motor an impeller with at least used a permanent magnet. From the number of revolutions and the Number of permanent magnets can the respective fundamental frequency and by changing the speed of the instrument motor the frequencies are adjusted.

Consequently is z. B. at a speed of 80 U / min of the engine and 3 Permanent magnets on the circumference of an arranged on the motor shaft impeller a frequency of 3.9 hz, corresponding to half the Schumann frequency reachable

Of the or the magnets are both on the circumference or in front of head arranged, wherein the polarity of all magnets is the same and preferably for use in the human area south pole. Engine and Impeller are in a housing or housing parts housed and can be due to the size without difficulty by hand Apply where necessary.

Of the Advantage of the device lies in providing significantly larger field strengths, the by z. B. neodymium magnets readily accessible to electronically electrodynamically generated fields across coils that require greater current to on such field strengths get. Here, the generated fields are only in the ring zones the coil and essentially not in the middle effective, while according to the proposal a concentrated field over the entire usable area is reached.

By the arrangement of permanent magnets on an impeller can to treating body area with full field strength according to the size of the permanent magnet be treated.

To the Purposes of attachment of the device on body are used in a conventional manner tension or stretch bands, the on the device are attached.

To Type of proposed embodiment can be at elevated Magnetic field power a much lower equipment cost compared to the known devices to reach. As a result, the breadth and effectiveness is above all self-help for a generally cost-effective health improvement elevated.

One embodiment is shown in the pictures.

In 1 is the instrument engine 1 with 80 mA mileage and 80 revolutions / min. represented on the shaft 2 the impeller 3 is placed on the circumference of permanent magnets 4 in threes. 2 shows the impeller 3 with 2 permanent magnets 4 in plan view and 3 the cross section of the impeller 3 with the 2 opposite permanent magnets 4 ,

4 shows the attachment of 2 permanent magnets 4 in front of the wheel 3 ,

By combination of the permanent magnet arrangement 1 and 4 is the formation of a spatial magnetic field achievable.

With the interpretation after 2 a pulsation frequency of 3.9 hz is achieved at a number of revolutions of the instrument motor 1 from 80 rpm. instrument engine 1 with impeller 3 is appropriate 5 in a housing 5 Housed on the surface of the housing 5 is still a field strength of at least approx. 180 mT available, if the permanent magnets approx. 350 mT.

To equip the device belongs to 5 the plug connection 6 as well as the switch 7 and the operation control lamp as diode B.

The further equipment of the device can be adjusted by voltage stabilizer on the one hand for constant speed or by Potentiometer in circuit for voltage change done so that other revolutions and thus reaches frequencies can be.

It arises in the proposed way of producing a strong magnetic field by rotation of permanent magnets as well as with their attachment and design and by the speed variants a universally easily usable device without electronic means to use.
