Dispositivo electrónico para diatermia.Electronic device for diathermy.
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
Este dispositivo, mediante diatermia por corrientes conducidas, es eficaz en múltiples aplicaciones en el campo de la electromedicina y en el de la electroestética.This device, by diathermy by conducted currents, is effective in multiple applications in the field of electromedicine and in the field of electrostatics.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
La diatermia es el empleo de corrientes eléctricas especiales para elevar la temperatura de tejidos vivos con fines terapéuticos. El aumento de la temperatura de los tejidos vivos puede ser no intencionada como en el caso de los dispositivos de electrocirugia, o intencionada como sucede con los dispositivos con usos terapéuticos o de electroestética . El aumento de temperatura del tejido vivo mediante diatermia se consigue transmitiendo energía al mismo mediante dos métodos: por corrientes inducidas (electrodos sin contacto con el tejido) y por corrientes conducidas. En la diatermia por corrientes conducidas se aplican dos electrodos en contacto con el tejido vivo y se produce una circulación de corriente entre los dos electrodos que atraviesa el tejido vivo que encuentra a su paso. La corriente que circula eleva la temperatura del tejido por el efecto Joule debido a la resistencia del propio tejido. Con el acoplamiento por contacto (corrientes conducidas) existen dos métodos de aplicación: el método capacitivo y el método resistivo. En diatermia con acoplamiento por contacto los electrodos normalmente son asimétricos, en ese caso, y debido a la densidad de corriente, el mayor aumento de la temperatura se produce en los tejidos más próximos al electrodo activo (el de menor tamaño) . En el método resistivo los dos electrodos son metálicos sin aislar. En el método capacitivo los dos electrodos son metálicos, pero uno de ellos tiene una capa aislante. • Diathermy is the use of special electrical currents to raise the temperature of living tissues for therapeutic purposes. The increase in the temperature of living tissues may be unintended as in the case of electrosurgical devices, or intentional as with devices with therapeutic or electrostatic uses. The increase in temperature of living tissue by diathermy is achieved by transmitting energy to it by two methods: by induced currents (electrodes without contact with the tissue) and by conducted currents. In the diathermy by conducted currents, two electrodes are applied in contact with the living tissue and there is a circulation of current between the two electrodes that crosses the living tissue that is in its path. The circulating current raises the temperature of the tissue by the Joule effect due to the resistance of the tissue itself. With the coupling by contact (conducted currents) there are two methods of application: the capacitive method and the resistive method. In diathermy with contact coupling the electrodes are normally asymmetric, in that case, and due to the current density, the greatest increase in temperature occurs in the tissues closest to the active electrode (the smaller one). In the resistive method the two electrodes are metallic without insulating. In the capacitive method the two electrodes are metallic, but one of them has an insulating layer. •
En general, la frecuencia de la señal aplicada en el método de acoplamiento sin contacto ha de ser muy superior a la frecuencia de la señal aplicada en el método de acoplamiento con contacto.In general, the frequency of the signal applied in the contactless coupling method must be much higher than the frequency of the signal applied in the contactless coupling method.
La diatermia por corrientes conducidas se ha mostrado como una herramienta muy eficaz en múltiples aplicaciones del campo de la electromedicina y de la electroestética . Son conocidos varios dispositivos de diatermia, algunos de ellos portátiles, aplicables a la electrocirugia con función de electrocoagulación, con fines hematógenos o para promover cicatrizaciones, no produciéndose en ninguno de ellos un aumento de la temperatura del tejido vivo para terapia.Conducted current diathermy has been shown as a very effective tool in multiple applications in the field of electromedicine and electrostatics. Several diathermy devices are known, some of them portable, applicable to electrosurgery with electrocoagulation function, for hematogenous purposes or to promote scarring, not causing an increase in the temperature of living tissue for therapy in any of them.
SUMARIO DE LA INVENCIÓNSUMMARY OF THE INVENTION
Es objeto de la presente invención un nuevo y pequeño dispositivo de diatermia portátil y manual adecuado para el cuidado epidérmico, fundamentalmente para la zona facial, pero no excluyente de otras zonas corporales, con objeto de disminución de arrugas, estrias, flacidez, cicatrices, etc., y el aumento de la hidratación.The object of the present invention is a new and small portable and manual diathermy device suitable for epidermal care, mainly for the facial area, but not exclusive of other areas. body, in order to reduce wrinkles, stretch marks, sagging, scars, etc., and increase hydration.
El dispositivo en cuestión produce un aumento de la temperatura en: la dermis, la epidermis y en capas más profundas como por ejemplo el músculo en función de sus resistencias eléctricas al paso de la corriente eléctrica a su través, mediante un mango aplicador. Con este aumento de la temperatura se consigue un importante incremento de la circulación sanguínea. También se produce una agradable sensación de relajamiento y un incremento del nivel de oxigeno, aportando una revitalización muy importante en la zona tratada que se aprecia a los pocos minutos del tratamiento.The device in question produces a temperature increase in: the dermis, the epidermis and in deeper layers such as the muscle, depending on its electrical resistance to the passage of the electric current through it, by means of an applicator handle. With this increase in temperature, a significant increase in blood circulation is achieved. There is also a pleasant sensation of relaxation and an increase in the level of oxygen, providing a very important revitalization in the treated area that can be seen within a few minutes of treatment.
Aunque fundamentalmente el aparato está pensado para el uso facial en personas, también se puede aplicar a otras partes del cuerpo e incluso a animales . El dispositivo está formado por un mango ergonómico que integra dos electrodos metálicos en contacto con el tejido vivo a tratar, siendo la corriente que circula por el tejido por conducción. El objetivo es aumentar la temperatura de forma local. El indicado mango comprende un mando de control que regula la potencia de salida, pudiendo sujetar el mango y accionar el dispositivo con una sola mano. El dispositivo se alimenta preferentemente con pilas o baterías recargables integradas en el mismo mango aplicador, por lo que puede ser autónomo de la red eléctrica, si bien podría también ser alimentado directamente de la red eléctrica mediante un cable de conexión flexible.Although the device is primarily intended for facial use in people, it can also be applied to other parts of the body and even to animals. The device is formed by an ergonomic handle that integrates two metal electrodes in contact with the living tissue to be treated, the current flowing through the tissue by conduction. The goal is to increase the temperature locally. The indicated handle comprises a control knob that regulates the output power, being able to hold the handle and operate the device with one hand. The device is preferably powered by batteries or rechargeable batteries integrated in the same applicator handle, so it can be autonomous from the mains, although it could also be powered directly from the mains using a flexible connection cable.
Los tratamientos se efectúan mediante un mango aplicador en el que en un extremo se hallan ubicados los dos electrodos metálicos sin capa aislante, aunque en una variante uno o ambos electrodos pueden tener una capa aislante. Ambos electrodos han de ser de material biocompatible adecuado para el tratamiento de la diatermia sobre el cuerpo humano.

La potencia de salida puede ser variable mediante un mando regulador.The treatments are carried out by means of an applicator handle in which at one end the two metal electrodes are located without an insulating layer, although in one variant one or both electrodes can have an insulating layer. Both electrodes must be of biocompatible material suitable for the treatment of diathermy on the human body. The maximum output power can be of the order of 20 W, however a typical value can be 6 W. The output power can be variable by means of a regulating control.
La frecuencia- de la señal aplicada puede estar en un margen de 100 kHz a 10 MHz de forma que no se produzca una estimulación nerviosa, y su valor no es fundamental para la correcta funcionalidad del dispositivo.The frequency of the applied signal can be in a range of 100 kHz to 10 MHz so that nerve stimulation does not occur, and its value is not essential for the correct functionality of the device.

DESCRIPCIÓN DETALIADADETAILED DESCRIPTION
De acuerdo con los dibujos, el dispositivo electrónico para diatermia comprende dos electrodos (1) y (2) instalados próximos entre si en un útil (3) mediante el cual se aplican juntamente en la zona a tratar. Los dos electrodos son preferentemente metálicos, sin embargo uno o ambos podrian tener una capa aislante. El útil (3) consiste en un mango ergonómico (4) formando un cabezal inclinado (5) con un plano de aplicación (6) donde están instalados los dos electrodos (1) y (2) próximos entre si.According to the drawings, the electronic diathermy device comprises two electrodes (1) and (2) installed next to each other in a tool (3) by which they are applied together in the area to be treated. The two electrodes are preferably metallic, however one or both could have an insulating layer. The tool (3) consists of an ergonomic handle (4) forming an inclined head (5) with an application plane (6) where the two electrodes (1) and (2) close to each other are installed.
El propio mango (4) comprende, en una versión preferente baterías recargables o pilas secas (7) para su funcionamiento con una autonomía suficiente para llevar a cabo uno o más tratamientos completos, un visualizador del nivel de potencia realizado por un "display" LCD (8), con dígitos de segmentos o con diodos LED (9), un mando (10) de control y regulación de la potencia de salida, un circuito impreso (11) que comprende un oscilador (12) con circuito de control, un amplificador de salida de alto rendimiento (13) y un circuito cargador de baterías (14) .The handle itself (4) comprises, in a preferred version rechargeable batteries or dry batteries (7) for operation with sufficient autonomy to carry out one or more complete treatments, a power level display made by an LCD display (8), with segment digits or with LEDs (9), a control (10) for controlling and regulating the output power, a printed circuit (11) that It comprises an oscillator (12) with a control circuit, a high performance output amplifier (13) and a battery charger circuit (14).
Con la referencia (15) se indica un mando de puesta en marcha que se instalará en el mango (4) en el caso de que el dispositivo no comprenda un sensor de movimiento para su conexión o desconexión.Reference (15) indicates a start-up command that will be installed in the handle (4) in the event that the device does not include a motion sensor for connection or disconnection.
Preferentemente los electrodos (1) y (2) estarán instalados en montaje fijo en el mango (4) con una separación de por ejemplo entre 0,3 cm y 1 cm, sin embargo en caso deseado podrían instalarse en un montaje que permitiera regular su separación. Para variar la anchura de la zona de aplicación el dispositivo podría comprender varios electrodos alineados pudiéndose conectar dos de ellos con el amplificador de radiofrecuencia.Preferably, the electrodes (1) and (2) will be installed in fixed mounting on the handle (4) with a separation of for example between 0.3 cm and 1 cm, however, if desired, they could be installed in a mounting that would allow to regulate their separation. To vary the width of the application area, the device could comprise several aligned electrodes, two of which can be connected to the radiofrequency amplifier.
En caso conveniente también cabe la posibilidad de instalar los electrodos con un ángulo regulable.If appropriate, it is also possible to install the electrodes with an adjustable angle.
Los dos electrodos (1) y (2) podrán ser de igual o similar tamaño, simétricos o asimétricos, y su superficie de aplicación será preferentemente plana aunque en algunos casos podrán presentar una configuración convexa u otra que convenga a su aplicación, siendo la superficie preferente de 0,5 cm2.The two electrodes (1) and (2) may be of equal or similar size, symmetrical or asymmetrical, and their application surface will be preferably flat although in some cases they may have a convex or other configuration that suits their application, the surface being preferably 0.5 cm 2 .
Con la referencia (16) se indica un conector de alimentación.A power connector is indicated with reference (16).
La variación de la potencia de salida con el mando (10) puede conseguirse variando la amplitud (modulación de amplitud) (Fig. 3 y Fig. 4), o modulando la señal de salida por una señal de pulsos o impulsos (Fig. 5 y Fig. 6) (modulación por ancho de pulsos PWM) . En las figuras 3, 4, 5 y 6 el eje de abscisas es el tiempo y el eje de ordenadas es la amplitud de la señal aplicada normalizada a la unidad. La figura 3 muestra la señal que proporciona la máxima potencia de salida. Para reducir esta potencia se puede disminuir la amplitud de la señal de salida como muestra la figura 4 (modulación de amplitud) . Otra manera de variar la potencia de salida es conectando la señal durante un cierto periodo de tiempo y desconectándola durante otro periodo de tiempo, de forma que la media de la potencia de salida se reduce cuando la duración de los pulsos se reduce (figuras 5 y 6) . La potencia de salida en las figuras 5 y 6 depende del tiempo durante el cual se aplica la señal. La potencia " que entrega la señal de la figura 6 es menor que la de la figura 5, siendo ésta a su vez menor que la potencia entregada por la señal de la figura 3. Este tipo de control de la potencia de salida se denomina modulación por ancho de pulso (PWM) .The variation of the output power with the control (10) can be achieved by varying the amplitude (amplitude modulation) (Fig. 3 and Fig. 4), or by modulating the output signal by a pulse signal or pulses (Fig. 5 and Fig. 6) (PWM pulse width modulation). In Figures 3, 4, 5 and 6 the axis of abscissa is the time and the axis of ordinates is the amplitude of the signal applied normalized to the unit. Figure 3 shows the signal that provides the maximum output power. To reduce this power, the amplitude of the output signal can be reduced as shown in Figure 4 (amplitude modulation). Another way to vary the output power is by connecting the signal for a certain period of time and disconnecting it for another period of time, so that the average output power is reduced when the pulse duration is reduced (Figures 5 and 6). The output power in Figures 5 and 6 depends on the time during which the signal is applied. The power " that delivers the signal of Figure 6 is less than that of Figure 5, which in turn is less than the power delivered by the signal of Figure 3. This type of output power control is called modulation by pulse width (PWM).
Las figuras 3, 4, 5 y 6 muestran una señal senoidal a titulo de ejemplo, sin embargo la señal aplicada también puede ser cuadrada, exponencial o triangular.Figures 3, 4, 5 and 6 show an example sinusoidal signal, however the applied signal can also be square, exponential or triangular.
Para variar la potencia se actúa sobre un mando que puede ser un pulsador, un potenciómetro, un "encoder" o un pequeño "joystick". To vary the power, a control is performed, which can be a button, a potentiometer, an "encoder" or a small "joystick".
