    Diathermy Treatment Device
    5 The present invention refers to diathermy treatment devices, it issay treatment by applying electrical currents in order to cause atemperature rise in parts of the human body. These currents can be usedfor pain treatments, rehabilitation, traumatology, dermatology and sports medicine,and also in the aesthetic specialty and aesthetic medicine. Sometimes the diathermy is
    10 called hyperthermia, although the term diathermy is preferred to distinguish this type of treatment.
    One class of known diathermy device comprises a generator, and at least one neutral or return electrode and one active application. The active electrode is usually of
    15 dimensions smaller than the return. To produce the diathermic effect, the generator is configured to produce alternating electricity at a frequency between 0.1 and 40 MHz, fixed or selectable. However, the safe range of diathermic application is between 100 kHz and 10 MHz. Generally, the diathermic current is generated in sinusoidal form. Generally, this current is applied with a constant sinusoidal function amplitude.
    20 It is also known to emit pulse trains, that is, alternating current pulses with constant amplitude interspersed for periods without current application. The average value of transmitted power is given by the effective amplitude of the signal, and the power, in turn, defines the amount of heat transmitted to the body and thus the diathermic effect.
    25 In the field of electric scalpels, electric current is used to cut tissues and dissect. Electric scalpels use alternating current usually at frequencies of 0.5 and 1.7 MHz and powers of 100-300 W, using a pointed electrode to concentrate the power. The heat produced cuts the tissues. In electric scalpels the modulation of the amplitude of the current is used to favor the coagulation of the
    30 proteins Coagulated proteins in this way seal the blood vessels sectioned by the scalpel to prevent bleeding.
    Document ES2464241 B1 discloses a d’Arsonval current generator that generates damped wave trains. These currents have an effect exclusively
    35 superficial and produce decongestant, decontracting, sterilizing effects,


    analgesic and neurotrophic, being therefore applicable for the treatment of anorectal conditions in a non-invasive way.
    Faced with this known state of the art, the present invention discloses a
    5 diathermy device comprising a generator, and at least one neutral electrode or ofreturn and an active application, the generator being configured to generate aalternating electric current with a frequency between 100 kHz and 10 MHz, and thatcharacterized in that the generator is configured to modulate the current in amplitudealternating electric with a modulation frequency between 18 kHz and 30 kHz.
    10 The applicant has verified that within an amplitude modulation in this frequency range (both alternating current and amplitude modulation) produces a compaction or density increase effect of the internal tissues.
    15 This new effect has interesting applications:
    - Therapeutics, since the compaction of internal tissues favors the stopping of small internal bleeds by the pressure mechanism and with this, the applicant has verified that recovery times are reduced.
    20-Aesthetic, since compacting tissue under the skin achieves a more satisfactory exterior aesthetic result than with only superficial techniques.
    Preferably the modulation is also of the sinusoidal type.
    25 The modulation index (ie, the ratio between the maximum amplitude and the minimum amplitude of the modulating wave) can be between more than 0% and less than 100%. The optimal modulation index may depend on the target tissue to be treated and the specific application. However, low values lead to a restricted modulatory effect and high values
    30 lead to excessive loss of power with respect to the unmodulated wave and with it the diathermic effect.
    Therefore, the amplitude modulation will preferably have a modulation index between 10% and 90%. The applicant has found that, with a general purpose, modulation rates of between 30 and 50% are especially convenient.


    For your better understanding, some drawings of an embodiment of the object of the present invention are attached by way of explanatory but not limiting example.
    Figure 1 is a graphical representation of an alternating current of the type used in5 diathermy
    Figure 2 is a graphic representation of an alternating current with modulated amplitude obtained according to the present invention.
    Figure 3 is a graphic representation of another alternating current with modulated amplitude obtained according to the present invention.
    Figure 1 shows a representation of voltage versus time of a diathermic current obtained by means of a diathermy device of known type. In particular, the
    The generator of diathermy currents generates an alternating electric current of sinusoidal type with a frequency between 0.1 MHz and 10 MHz. As can be seen, the signal, in this case, is of the continuous type (there are no pulse trains) and The amplitude of the current (that is, the maximum voltage value in each cycle) is constant.
    The present invention provides a generator of known type of amplitude modulation means (in this case, the voltage) of the alternating electric current, or configures the existing means so that the resulting current is the desired one. Since amplitude modulation of electrical signals is a widely known field of art, it is not necessary to explain such means in detail.
    Figure 2 shows a first example of a diathermic electric current according to the present invention. As can be seen, the current has the same frequency as the signal in Figure 1. However, the amplitude is modulated by a sinusoidal signal or wave. This apparent wave is called the modulating wave. The maximum values of
    30 amplitude follow a sinusoidal form with a frequency between 18 and 30 kHz.
    As can be seen, the modulation index, that is, the ratio between the maximum and the minimum amplitude of the modulating wave is approximately 40%.
    35 Likewise, in this example the modulation is of the continuous type, that is, there are no periods of current without modulation.


    Figure 3 shows a second example similar to the previous one in which the modulation index is 100%. This embodiment, in principle, is not as advantageous because it implies a considerable decrease in the transmitted power and, therefore, a decrease in the
    5 diathermic effect. If it is desired to compensate for the loss of diathermic effect (average power) with respect to the example of Figure 1, then it is necessary to increase the maximum voltage of the electric current without modulating, which may not be convenient due to risks of burn and / or electrocution.
    Although the invention has been presented and described with reference to embodiments thereof, it will be understood that these are not limiting of the invention, so that multiple constructive or other details that could be evident to the technicians of the sector could later be variable. of interpreting the subject matter disclosed in the present description, claims and drawings.
