Definitions
- the present invention relates to a device for magneto-therapy which presents important innovative characteristics with respect to those currently in use and extends their field of employment.
- Electromagnetic fields influence, among other things, cell membrane permeability, cell enzyme activity, calcium mobility and its velocity of migration through the membrane itself.
- the role of calcium in the transmission of intracellular signals, such as muscle contraction and relaxation, is scientifically recognised.
- Electromagnetic waves have been used as a non invasive tool to promote healing of bone fractures, obtaining significant successes and scientific recognition. Numerous studies confirm the influence of electromagnetic fields on calcium movement and on the piezoelectric organisation of bone structures, as well as their favourable action in the organisation of the cytoskeleton of the bone callus (calcification acceleration action). Electromagnetic fields also influence circadian wake and sleep rhythms.
- the devices for magneto-therapy currently in use generate magnetic fields with fixed frequencies, selectable manually. Since the optimal frequency of the field depends on the subject, on the type of treatment to be performed and on the earth's magnetic field, which varies from place to place, the experiments that are conducted do not have universal validity. It is therefore necessary to proceed by trial and error on a case by case basis, wasting a great amount of time, to attain the desired results.
- the object of the present invention is to allow effective magneto- therapy treatments of various kinds, without having each time to seek by trial and error the optimal conditions of adjustment for the device.
- Other aims are to perform an extremely localised action on a preselected point and to allow treatment on persons during their physical activity.
- the transducer that produces the magnetic field is fed pulses whose frequency is cyclically variable, from a minimum to a maximum, such as to delimit a range of values which is sure to include the optimal ones for any subject, wherever he or she may be located.
- the transducer further comprises an inductor with ferrite core, or the like, or reduced size, which generates an extremely focused field and thus can be applied exactly onto the pre-selected point, even to physically active persons.
- FIG. 1 shows a block diagram of the device.
- reference number 1 indicates a ramp generator, number 2 a voltage-controlled oscillator (VCO), number 3 a pulse generator circuit, number 4 a power amplifier and number 5 a transducer, which, fed by the amplified pulses, produces a pulsing magnetic field of suitable intensity.
- Reference numbers 6 and 7 indicate respectively a rechargeable battery and the related charging circuitry.
- the ramp generator 1 can in practice comprise the V_. integrated circuit IC1 shown at the top left in Table 2, 3456 type or equivalent.
- the pulse generator circuit 3 comprises, in the example in Fig. 2, the remaining part of integrated circuit IC1, shown at the bottom left.
- the voltage-controlled oscillator or VCO 2 is obtained with the integrated circuit IC2, 4046 type or equivalent.
- the power amplifier 4 comprises the transistor TR1, BC337 type or equivalent.
- the transducer 5 is represented by inductor LI.
- the device At start-up, the device generates pulses of pre-set width, typically 60 microseconds, with repetition frequency that depends on the VCO 2 and on the ramp generator 1 connected thereto.
- the minimum pulse repetition frequency specified is 3 Hz
- the maximum frequency is 65 Hz.
- variable frequency pulses thus generated are amplified by the power amplifier 4, that drives the magnetic transducer 5, which comprises a small coil of reduced size, with core made of ferrite, or the like.
- the amplitude of the amplified pulses and the characteristics of the transducer are such as to produce a magnetic field of appropriate intensity.
- Some components of the device can be adjustable, to allow device calibration.
- circuit configurations different from the one shown could be adopted: for instance, the electronic circuit could be variously integrated and even programmable.
