Abstract
The utility model relates to an electrically variable magnetic therapy apparatus, comprising a power amplifier and a ferromagnet which is wound with coil curls, etc. The utility model can be connected with a radio set, a recorder, etc.; the human body can be conducted with the magnetic therapy by the daedal magnetic field which is generated by the music current or other electrical signals; different magnetic fields can be selected according to different conditions; the therapeutic effect can be enhanced. The magnetic therapy apparatus can also be provided with a signal generator for convenient operation.
Description
This utility model is a kind of medical Magnetotherapeutic apparatus, and is particularly a kind of with the synthetic electric adjustable magnetic field therapy apparatus of music current.
Existing magnetotherapy appliance generally is to treat with Magnet placement therapentic part or certain acupuncture point, and its intensity of the magnetic field of this magnetic therapy is single and constant.Also have a kind of machinery modulation magnetic pole, as shown in Figure 1, by two magnetic pole rotations of driven by motor N, S, thereby produce regular alternating magnetic field, in order to carry out magnetic therapy, its changes of magnetic field as shown in Figure 2.The magnetic field that above Magnetotherapeutic apparatus produces all is the comparison dullness, and tissue easily produces adaptability when receiving treatment, curative effect is weakened.
The purpose of this utility model is to provide a kind of various variation magnetic field that can produce, and can select the electric adjustable magnetic field therapy apparatus of different magnetic field according to the state of an illness for use.
This utility model is achieved in that with being wound with the ferromagnet of coil as the electric adjustable magnetic utmost point, electricity transfers polar coil to link to each other with power amplifier with lead, power amplifier is provided with interface, the amplifier of signal generation apparatus such as recorder, radio is provided with an interface, the interface of this magnetic field therapy apparatus interface and signal generation apparatus is connected with lead.After signal generator sent music or other signal of telecommunication (as sine wave, impulse wave etc.), the electric adjustable magnetic utmost point promptly produced the magnetic field of various variation, and this magnetic field can be selected by adjusting signal generator or tape.Ferromagnet can be made with permanent magnet material or with soft magnetic materials such as silicon steel, pure iron, ferrites.The electricity adjustable magnetic utmost point is loaded in the box body that has bonnet, protecgulum.
This electric adjustable magnetic field therapy apparatus is that electric current, the voltage by modulated or not modulated music or other signal of telecommunication (as sine wave, impulse wave, triangular wave etc.) acts on pole coil, and produces the pulsation alternating magnetic field, the physical therapy machine that human body is treated.Will be through selection, the useful various music of curing the disease of energy or other signal of telecommunication are recorded into various prescription tapes according to different needs.After this machine and recorder connection, can treat by the electricity consumption adjustable magnetic utmost point.Also can connect with the music of broadcasting and treat with radio.The waveform of music current is very complicated and Protean, thereby the magnetic field that produces also is Protean, and this action of a magnetic field is in human body, and each all is a kind of new stimulation constantly, can not resemble and make human body produce adaptability the existing magnetic field therapy apparatus, thereby improve the therapeutic effect of magnetotherapy.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the polar structure chart of machinery modulation
Fig. 2 is the polar changes of magnetic field figure of machinery modulation
Fig. 3 is the polar structure chart of electric adjustable
Fig. 4 is the changes of magnetic field figure of electric adjustable magnetic field therapy apparatus
Fig. 5 is the electrical schematic diagram of electric adjustable magnetic field therapy apparatus
Fig. 1 is that existing mechanical is modulated polar structure chart; Fig. 2 is its changes of magnetic field figure, and its magnetic field is dull and lacks variation as can be seen.Fig. 3 is the field structure figure of this utility model magnetic field therapy apparatus, and ferromagnet among the figure (5) is wound with coil (4), and box body (2) has bonnet (1) and protecgulum (3).Fig. 4 is the oscillogram in the magnetic field of this magnetic field therapy apparatus generation, and the waveform of music current is very complicated, and it is combined according to the requirement of music to melody, rhythm, speed, dynamics by the sine wave of some single-frequencies.The audio signal of this complexity is by after amplifying, and its each part can be regarded the synthetic train of pulse of multiple radio-frequency component as, and these pulses have complicated music rule.The various characteristics that has the music electric pulse by the synthetic magnetic field of music equally.Fig. 6 is the electrical schematic diagram of this machine, and (6) are power amplifier among the figure, and it has interface (7), in order to connect signal generator.For the convenience on using, itself can be provided with signal generation apparatus such as radio reception, recording the electric adjustable magnetic field therapy apparatus, and power amplifier (6) is directly connected on the amplifying device of signal generator.Can be according to certain standard recording music prescription tape of compiling, to adapt to the different state of an illness; Also can use the signal of telecommunication of other waveform of magnetic recording (triangular wave, pulse, sine wave) as signal source.The magnetic pole of this magnetic field therapy apparatus can directly not contact skin, and the patient does not have uncomfortable sensation.Electrotherapy need contact electrode with human body skin, but some position (as the hair position) should not place electrode, and this magnetic field therapy apparatus has solved this problem.
Claims (2)
1, a kind of electric adjustable magnetic field therapy apparatus, it is characterized in that with being wound with the electric adjustable magnetic utmost point of the ferromagnet (5) of coil (4) as magnetic field therapy apparatus, the extremely outer dress of electricity adjustable magnetic has the box body (2) of bonnet (1), protecgulum (3), and coil (4) links to each other with power amplifier (6), and power amplifier (6) is provided with interface (7).
2, according to the described electric adjustable magnetic field therapy apparatus of claim 1, it is characterized in that this machine has signal generation apparatus, power amplifier (6) directly links to each other with the amplifier of signal generation apparatus.
