Description

SISTEMA PARA TRATAMIENTO MEDIANTE CHOQUES TÉRMICOS  SYSTEM FOR TREATMENT THROUGH THERMAL SHOCK

DE LESIONES EN LA PIEL PROVOCADAS POR ACNÉ  OF SKIN INJURIES CAUSED BY ACNE

CAMPO TÉCNICO DE LA INVENCIÓN TECHNICAL FIELD OF THE INVENTION

La presente invención tiene su campo de aplicación preponderante en el tratamiento de afecciones causadas por acné en el rostro de los pacientes a través de un método de aplicación tópica. The present invention has its preponderant field of application in the treatment of conditions caused by acne on the face of patients through a method of topical application.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

El acné afecta a más del 90% de todos los adolescentes, casi el 50% de todas las mujeres adultas y el 25% de todos los adultos. Los tratamientos más comunes son medicamentos tópicos, orales y combinaciones de ambos. Las alternativas a la medicación incluyen la radiación UV, el tratamiento con láser o la abrasión y tratamientos térmicos (frío y calor). Dicho esto, la presente invención tiene como objetivo un método de tratamiento de acné mediante la aplicación de choques térmicos (frío y calor). A continuación se presenta una breve descripción de patentes actuales en relación al tema, con el fin de hacer referencia y comparación con la presente invención. Acne affects more than 90% of all adolescents, almost 50% of all adult women and 25% of all adults. The most common treatments are topical, oral medications and combinations of both. Alternatives to medication include UV radiation, laser or abrasion treatment and heat treatments (cold and heat). That said, the present invention aims at a method of acne treatment by applying thermal shocks (cold and heat). Below is a brief description of current patents in relation to the subject, in order to make reference and comparison with the present invention.

Los dispositivos descritos en la patente US20060142750 emplean la aplicación de calor para el tratamiento de afecciones de la piel, tales como acné, verrugas, ampollas frías, piel manchada o arrugas finas. Típicamente, las temperaturas máximas empleadas son de aproximadamente 70 °C a 400 *C mediante los dispositivos, su aplicación en la piel es de aproximadamente de 1 segundo. La conducción térmica transfiere el calor del dispositivo a la piel y causa una respuesta biológica que acelera el aclaramiento del acné, trata la piel manchada y afecciones de acné. El calor total transferido es lo suficientemente bajo para prevenir quemaduras. Similarmente la patente US6635075 también describe un dispositivo como el anterior pero se diferencia en que integra un sensor de temperatura para evitar quemaduras durante el largo tiempo de aplicación (minutos) y además la temperatura máxima permitida es de 62 9 C. Con relación, en la patente CN2695026 se describe un tratamiento térmico (conducción de calor) de baja temperatura mediante luz fría azul (longitud de onda de 415 nm) aplicándose una mascarilla plástica en la cara antes de la aplicación de la luz. The devices described in US20060142750 employ the application of heat to treat skin conditions, such as acne, warts, cold blisters, stained skin or fine wrinkles. Typically, the maximum temperatures used are from about 70 ° C to 400 * C through the devices, their application on the skin is about 1 second. Thermal conduction transfers heat from the device to the skin and causes a biological response that accelerates acne clearance, treats stained skin and acne conditions. The total heat transferred is low enough to prevent burns. Similarly, US6635075 also describes a device like the previous one but it differs in that it integrates a temperature sensor to avoid burns during the long application time (minutes) and in addition the maximum allowed temperature is 62 9 C. CN2695026 patent describes a low heat treatment (heat conduction) temperature by means of blue cold light (wavelength of 415 nm) applying a plastic mask on the face before the application of the light.

Así mismo, la patente US7963959 proporciona aparatos, sistemas y métodos en los que un aparato trata una lesión de acné usando un fluido criógeno a una temperatura de -5 *C. El aparato contemplado se puede usar preferiblemente para tratar la piel de la mano de un paciente, aunque también se contempla el tratamiento de la piel de la cara, espalda u otras áreas. Con relación, la patente US6226996 también reclama un dispositivo como el anterior, pero se diferencia en que rocía una niebla criogénica sobre toda el área de tratamiento. En la patente US6413252 se discute un dispositivo de tratamiento más complejo que incluye un microscopio confocal para ver secciones del área de tratamiento. El área puede congelarse inundándola con un fluido criogénico. Likewise, US7963959 provides devices, systems and methods in which an apparatus treats an acne lesion using a cryogenic fluid at a temperature of -5 * C. The contemplated apparatus can preferably be used to treat the skin of the hand of a patient, although the treatment of the skin of the face, back or other areas is also contemplated. In relation, US6226996 also claims a device like the previous one, but it differs in that it sprays a cryogenic mist over the entire treatment area. A more complex treatment device that includes a confocal microscope for viewing sections of the treatment area is discussed in US6413252. The area can be frozen by flooding it with a cryogenic fluid.

Las invenciones anteriormente mencionadas tmplementan la aplicación de frío o calor, pero no combinados. Para lograr el cambio brusco en temperatura, la presente invención propone la implementación de celdas Peltier. The above-mentioned inventions implement the application of cold or heat, but not combined. To achieve the sudden change in temperature, the present invention proposes the implementation of Peltier cells.

DESCRIPCION DETALLADA DE LA INVENCIÓN DETAILED DESCRIPTION OF THE INVENTION

Breve descripción de las figuras: La figura 1 es una vista tridimensional del dispositivo con encapsulado tipo pluma para el arreglo de componentes que conforman el sistema como se detalla en la presente invención. Brief description of the figures: Figure 1 is a three-dimensional view of the device with pen-type encapsulation for the arrangement of components that make up the system as detailed in the present invention.

Las figuras 2a y 2b muestran vistas tridimensionales seccionadas del dispositivo descrito en la presente invención, donde se indican a detalle las celdas Peltier [Elementos C] y su posición espacial paralela unas respecto a las otras. Se nombra la celda que hace contacto con la piel del paciente [Elemento Cl] y la celda más lejana de la piel del paciente [Elemento Cn] que intercambia calor con el ambiente. El ventilador [Elemento F] que se posiciona por debajo de la resistencia térmica (Elemento R]. Figures 2a and 2b show sectioned three-dimensional views of the device described in the present invention, where the Peltier cells [Elements C] and their parallel spatial position are shown in detail relative to the others. The cell that makes contact with the patient's skin is named [Element Cl] and the cell furthest from the patient's skin [Element Cn] that exchanges heat with the environment. The fan [Element F] that is positioned below the thermal resistance (Element R].

La figura 3 muestra las rejillas del encapsulado [Elementos O], que permiten que el ventilador expulse el calor transmitido por la celda n [Elemento Cn de la Figura 2] hacia el ambiente.  Figure 3 shows the gratings of the package [Elements O], which allow the fan to expel the heat transmitted by cell n [Element Cn of Figure 2] towards the environment.

La figura 4 es el diagrama de conexiones eléctricas de las Celdas Peltier, conectados a una fuente de alimentación de voltaje común [V] e interruptores con arreglo de puente "H" [SI, S2, S3, S4]. Para generar la absorción de calor en la piel del paciente se cierran solamente los interruptores SI y S4, de tal forma que la corriente circula de izquierda a derecha en las celdas [Cl, C2, Cn]. Para polarizar dichas celdas [Cl, C2, Cn] de manera contraria, ahora para transmitir calor hacia la piel, se cierran solamente los interruptores S2 y S3, de tal forma que la corriente circulará de derecha a izquierda sobre los componentes mencionados [Cl, C2, Cn].  Figure 4 is the electrical connection diagram of the Peltier Cells, connected to a common voltage power supply [V] and switches with "H" jumper arrangement [SI, S2, S3, S4]. To generate heat absorption in the patient's skin, only switches SI and S4 are closed, so that current flows from left to right in the cells [Cl, C2, Cn]. To polarize said cells [Cl, C2, Cn] in the opposite way, now to transmit heat to the skin, only switches S2 and S3 are closed, so that the current will flow from right to left over the mentioned components [Cl, C2, Cn].
