OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La invención se refiere a un equipo concebido para la irradiación de microondas y consiguiente aplicación de las mismas sobre pacientes, en orden a conseguir unos efectos terapéutico de rehabilitación, especialmente en las dolencias de origen reumático.The invention relates to a device designed for the irradiation of microwaves and consequent application thereof on patients, in order to achieve therapeutic effects of rehabilitation, especially in ailments of rheumatic origin.
El equipo tiene por objeto conseguir una eficaz penetración de las microondas en los tejidos más profundos de la zona del paciente en la que se apliquen aquellas, así como irradiar microondas única y exclusivamente en la zona deseada.The purpose of the equipment is to achieve an effective penetration of the microwaves into the deepest tissues of the area of the patient in which they are applied, as well as to radiate microwaves only and exclusively in the desired area.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Desde hace varias décadas ha sido admitida la utilización de microondas de elevada frecuencia para fines terapéuticos, por lo que a lo largo del tiempo se han ido concibiendo equipos generadores de microondas con el fin de aplicar éstas como terapia de rehabilitación en determinadas dolencias, fundamentalmente de origen reumático.The use of high-frequency microwaves for therapeutic purposes has been admitted for several decades, which is why microwave generators have been conceived over time in order to apply them as rehabilitation therapy in certain diseases, mainly of rheumatic origin
Como es conocido, las microondas penetran en los tejidos y debido a su elevada frecuencia las mismas producen calor, con el consiguiente efecto terapéutico de la zona a tratar.As is known, microwaves penetrate the tissues and due to their high frequency they produce heat, with the consequent therapeutic effect of the area to be treated.
Pues bien, las microondas suelen ser conducidas
- 2 -Well, microwaves are usually driven - two -
desde una válvula generadora, mediante un cable coaxial, a una antena emisora situada dentro de un irradiador, desde el cual las microondas son irradiadas al exterior, para su aplicación sobre la zona a tratar del paciente.from a generating valve, by means of a coaxial cable, to a transmitting antenna located within an irradiator, from which the microwaves are irradiated to the outside, for application on the area to be treated by the patient.
Como es lógico, la superficie de irradiación de microondas depende de la superficie y de la figura geométrica del irradiador, siendo de uso muy generalizado irradiadores que tienen forma redonda.Naturally, the microwave irradiation surface depends on the surface and the geometrical shape of the irradiator, with round-shaped radiators being widely used.
Es evidente que la absorción de microondas de elevadas frecuencias, por los tejidos orgánicos que se encuentran dentro del campo de irradiación, depende del espesor y la constitución bioquímica de los tejidos, de manera que los tejidos más gruesos y con mayor contenido de agua absorben las microondas fácilmente, produciéndose un rápido calentamiento de aquellos. La absorción de microondas por dicho tipo de tejidos implica la imposibilidad de penetración en los tejidos más profundos.It is evident that the absorption of microwaves of high frequencies, by the organic tissues that are within the field of irradiation, depends on the thickness and the biochemical constitution of the tissues, so that the thickest and most watery tissues absorb the Microwave easily, producing rapid heating of those. The absorption of microwaves by said type of tissues implies the impossibility of penetration into deeper tissues.
Sin embargo, en tejidos de menor grosor, la absorción y la pérdida de microondas es menor, por lo que éstas penetran con mayor intensidad en los tejidos más profundos.However, in tissues of smaller thickness, the absorption and loss of microwaves is lower, so they penetrate more deeply into deeper tissues.
Por consiguiente, en la irradiación o aplicación de microondas sobre los pacientes, es deseable que los tejidos externos sean lo más delgados posible para reducir la pérdida de microondas y conseguir que éstas alcancen los tejidos más profundos.Therefore, in the irradiation or application of microwaves on patients, it is desirable that the external tissues be as thin as possible to reduce the loss of microwaves and achieve that they reach deeper tissues.

Por otro lado, el equipo de la invención está igualmente concebido para conseguir un direccionamiento de la irradiación de las microondas, o lo que es lo mismo una aplicación precisa sobre la zona que se pretende tratar, quedando la periferia a esa zona sin posibilidad de recibir irradiación, evitando con ello el calentamiento de los tejidos laterales más gruesos, es decir, los que quedan situados externamente a la zona concreta de irradiación o aplicación de las microondas, lo que resulta de gran importancia en el tratamiento de tejidos próximos a órganos que no deben ser tratados con microondas, como por ejemplo, el tratamiento de las vértebras próximas a la masa cerebral, los tejidos próximos a los ojos, los tejidos cercanos a los testículos, etc.On the other hand, the equipment of the invention is also designed to achieve a direction of microwave irradiation, or what is the same a precise application on the area to be treated, leaving the periphery to that area without the possibility of receiving irradiation, thereby preventing heating of the thicker lateral tissues, that is, those that are located externally to the specific area of irradiation or application of microwaves, which is of great importance in the treatment of tissues near organs that do not They should be treated with microwaves, such as the treatment of vertebrae near the brain mass, tissues near the eyes, tissues near the testicles, etc.
Más concretamente, el equipo de la invención se basa en la asociación y conjunción funcional de tres aspectos o elementos fundamentales, uno correspondiente a un cabezal de presionado sobre el tejido periférico del paciente, comprimiendo a dicho tejido y haciéndolo más delgado, en donde dicho cabezal es desplazable mecánicamente con un recorrido constante, todo ello de manera que el contacto entre el repetido cabezal y la zona a irradiar del paciente se produce de forma suave, no impactante y sin ningún tipo de traumatismo, evitando así el riesgo de posibles lesiones en el organismo.

Los muelles (23) limitadores de la presión del cabezal (11) están situados entre unas arandelas (25) en funciones de tope dispuestas sobre los tramos (16') de los ejes (16).projection (20) thereof, is in permanent contact with the cam (21) by virtue of a spring (24) disposed between the inner face of said bridge (19) and the disk (18) housing separator (8) with respect to of the cylindrical body (9) already referred to. The springs (23) limiting the head pressure (11) are located between washers (25) in stop functions arranged on the sections (16 ') of the shafts (16).
El cabezal (11) , a través de la parte o piezaThe head (11), through the part or piece
(14), emerge a través de la abertura frontal (26) prevista al efecto en el regulador de presión (27) del propio cabezal (11) , regulador (27) que queda montado sobre la embocadura que determina la tapa frontal de protección (28) en la que queda situado tal regulador (27) dotado de la abertura frontal (26) para emergencia del cabezal (11) .(14), emerges through the front opening (26) provided for this purpose in the pressure regulator (27) of the head itself (11), regulator (27) that is mounted on the mouth that determines the protective front cover ( 28) in which such regulator (27) is provided with the front opening (26) for emergency head (11).
Pues bien, dicho regulador (27) es susceptible de desplazarse hacia adelante respecto de la embocadura que determina la tapa (28) , por empuje de unos casquillos (29) situados en correspondientes pasos axiales (30) del cuerpo correspondiente a la carcasa (8) , casquillos (29) dotados de una pareja de orificios roscados (31) relacionados con parejas de separadores (32) que se ubican en correspondientes orificios (33) de un disco (34) a través del cual es pasante el vastago (35) de un mando de accionamiento (36) , de manera tal que mediante éste es posible desplazar los casquillos (29) , en virtud de que la pareja de separadores (32) quedan ubicadas en ventanas (37) previstas al efecto en la superficie lateral de la carcasa (8) . Es decir, que el accionamiento del disco (34), en sentido axial, lleva consigo el desplazamiento de los casquillos (29) y por lo tanto del regulador (27) , mientras que el presionado del extremo
- 10 -Well, said regulator (27) is capable of moving forward with respect to the mouth that determines the cover (28), by pushing some bushings (29) located in corresponding axial passages (30) of the body corresponding to the housing (8). ), bushings (29) provided with a pair of threaded holes (31) related to pairs of spacers (32) that are located in corresponding holes (33) of a disc (34) through which the rod (35) is passed through of a drive control (36), so that by means of this it is possible to move the bushings (29), by virtue of which the pair of spacers (32) are located in windows (37) provided for this purpose on the lateral surface of the housing (8). That is to say, that the drive of the disc (34), in axial direction, carries with it the displacement of the bushings (29) and therefore of the regulator (27), while the pressing of the end - 10 -
del vastago (35) sobre la superficie lateral de la carcasa (8) , tras el accionamiento del mando (36) , lleva consigo el bloqueo del mecanismo y por lo tanto la posibilidad de desplazamiento de los casquillos (29) , manteniendo el regulador (27) inamovible.of the rod (35) on the lateral surface of the housing (8), after actuation of the control (36), carries with it the locking of the mechanism and therefore the possibility of displacement of the bushings (29), maintaining the regulator ( 27) immovable.
Cuando se realiza el desbloqueo, por accionamiento en sentido contrario del mando (36) , y correspondiente separación del extremo del vastago (35) de la superficie lateral de la carcasa (8) , el desplazamiento en un sentido, mediante el disco (34) del regulador (27) , proporcionará una mayor separación entre éste y el cuerpo del irradiador, posición que corresponde a una mínima presión del cabezal (11) sobre los tejidos del paciente, mientras que cuando la separación entre el regulador (27) y el cuerpo del irradiador es mínima, entonces la presión del cabezal (11) sobre los tejidos del pacientes es máxima.When unlocking is carried out, by actuation in the opposite direction of the control (36), and corresponding separation of the rod end (35) from the lateral surface of the housing (8), the displacement in one direction, by means of the disk (34) of the regulator (27), will provide a greater separation between it and the body of the irradiator, a position that corresponds to a minimum pressure of the head (11) on the patient's tissues, while when the separation between the regulator (27) and the body of the irradiator is minimal, then the head pressure (11) on the patient's tissues is maximum.
Sobre la tapa protectora (28) prevista en el frente de la carcasa (8) del irradiador, y en la que se sitúa el cabezal (11) con el regulador (27) , van montadas dos láminas reflectantes (38) susceptibles de cambiar su posición angular mediante el desplazamiento de unos ejes (39) a los que están vinculados unos resortes (40) que por uno de sus extremos están fijados a unos pivotes (41) solidarios a la superficie lateral de la carcasa (8) , mientras que por su otro extremo los resortes o muelles (40) están vinculados a los ejes (39) , relacionados con piezas (42) solidarias a prolongaciones (34') de los discos (34) referidos con anterioridad, de manera que el desplazamiento de los discos laterales (34) , y por lo tanto de sus prolongaciones (341), llevará consigo el tensado o destensado de los muelles (40) y por lo tanto el accionamiento de los ejes (39) haciendo variar la
- 11 -On the protective cover (28) provided in the front of the housing (8) of the irradiator, and in which the head (11) is placed with the regulator (27), two reflective sheets (38) capable of changing its angular position by displacing axes (39) to which springs (40) are linked, which at one end are fixed to pivots (41) integral with the lateral surface of the housing (8), while at its other end the springs or springs (40) are linked to the shafts (39), related to parts (42) integral to extensions (34 ') of the discs (34) referred to above, so that the displacement of the disks lateral (34), and therefore of its extensions (34 1 ), will carry with it the tensioning or tensioning of the springs (40) and therefore the actuation of the shafts (39) by varying the - eleven -
posición angular de las láminas reflectoras (38) .angular position of the reflector sheets (38).
Esa variación angular, en sentido convergente, de tales láminas (38) , lleva consigo una reducción de la superficie del irradiador, y con ello la superficie del área irradiada.That angular variation, in convergent sense, of such sheets (38), entails a reduction in the surface of the irradiator, and with it the surface of the irradiated area.
Por lo tanto, la superficie de irradiación puede ser reducida al área del tejido periférico comprimido, es decir, más delgado por la presión del cabezal (11) .Therefore, the irradiation surface can be reduced to the area of the compressed peripheral tissue, that is, thinner by the pressure of the head (11).
La absorción de microondas por el tejido periférico no presionado, y por lo tanto más grueso, implica mayor calentamiento y pérdida de microondas en el mismo, y la imposibilidad de irradiación en los tejidos más profundos. En cambio, en el tejido comprimido y más delgado se reduce la absorción y la pérdida de microondas, aumentando de esta forma la capacidad de irradiación en los tejidos más profundos.The absorption of microwaves by the peripheral tissue not pressed, and therefore thicker, implies greater heating and loss of microwaves therein, and the impossibility of irradiation in the deeper tissues. On the other hand, in the compressed and thinner tissue the absorption and loss of microwaves is reduced, thus increasing the irradiation capacity in the deeper tissues.
Con la limitación de la superficie de irradiación en el área del tejido comprimido, mediante las láminas reflectoras (38) , se evita el calentamiento de los tejidos laterales más gruesos, lo que tiene una gran importancia en el tratamiento de tejidos próximos a órganos que no deben ser tratados con microondas, como es por ejemplo, el tratamiento de las vértebras próximas a la masa cerebral, los tejidos en las proximidades de los ojos o los tejidos cercanos a los testículos.
With the limitation of the irradiation surface in the area of the compressed tissue, by means of the reflective sheets (38), the warming of the thicker lateral tissues is avoided, which is of great importance in the treatment of tissues near organs that do not they must be treated with microwaves, such as, for example, the treatment of the vertebrae close to the brain mass, the tissues in the vicinity of the eyes or the tissues near the testicles.
