La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un aparato depilador láser portátil de uso polivalente, aportando a la función a que se destina varias ventajas y características de novedad, que se describirán en detalle más adelante, que suponen una mejora frente a otros sistemas actualmente conocidos en el estado de la técnica para el mismo fin.

CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector técnico de la industria dedicada a la fabricación de aparatos de depilación por láser. ANTECEDENTES DE LA INVENCIÓN The scope of the present invention is part of the technical sector of the industry dedicated to the manufacture of laser hair removal devices. BACKGROUND OF THE INVENTION
La base científica de la depilación láser es el principio de la fototermolisis selectiva, que predice que se producirá una lesión térmica selectiva de una estructura pigmentada cuando se deposite un flujo luminoso suficiente a una determinada longitud de onda (absorbida por el objetivo) durante un tiempo menor o igual que el tiempo de relajación térmica del objetivo. The scientific basis of laser hair removal is the principle of selective phototermolysis, which predicts that a selective thermal lesion of a pigmented structure will occur when a sufficient luminous flux is deposited at a certain wavelength (absorbed by the target) for a period of time. less than or equal to the thermal relaxation time of the target.
La depilación láser se describió por primera vez en el año 1996. Las complicaciones son raras si se siguen los tratamientos recomendados, siendo el único efecto secundario más habitual el cambio temporal de pigmentación. Laser hair removal was first described in 1996. Complications are rare if the recommended treatments are followed, with the only most common side effect being temporary pigmentation change.
Los principios básicos de la depilación láser consisten en que la luz incidente sobre un tejido puede ser transmitida, reflejada, absorbida o dispersada, dependiendo de la composición del tejido y de la longitud de onda (color) de la luz. The basic principles of laser hair removal are that the light incident on a tissue can be transmitted, reflected, absorbed or dispersed, depending on the composition of the tissue and the wavelength (color) of the light.
Cada tipo de tejido en el cuerpo humano tiene un coeficiente de absorción que depende de sus componentes absorbentes específicos, también llamados cromóforos. Each type of tissue in the human body has an absorption coefficient that depends on its specific absorbent components, also called chromophores.
Los principales cromóforos del cuerpo humano son cuatro: The main chromophores of the human body are four:
- Hemoglobina (sangre) - Hemoglobin (blood)
- Melanina (piel, pelo, lunares) - Melanin (skin, hair, moles)
- Agua (en todos los tejidos biológicos) - Water (in all biological tissues)
- Proteínas (centros dispersores: enlaces covalentes presentes en los tejidos). - Proteins (dispersing centers: covalent bonds present in tissues).
Cuando la luz es absorbida por un cromóforo, su reacción (destrucción, vaporización, reducción o desactivación) depende de la intensidad de la luz y del tiempo de exposición. En el caso de la fotodepilación, se utiliza la melanina que contiene el folículo piloso como cromóforo absorbente de la energía luminosa. El folículo piloso es la parte de la piel que da crecimiento al cabello al concentrar células madre. When light is absorbed by a chromophore, its reaction (destruction, vaporization, reduction or deactivation) depends on the intensity of the light and the exposure time. In the case of photodepilation, melanin containing the hair follicle is used as an energy-absorbing chromophore bright. The hair follicle is the part of the skin that gives hair growth by concentrating stem cells.
La luz aplicada puede ser de dos tipos: The light applied can be of two types:
- Láser: coherente, monocromática, colimada (rubí, alexandrita, diodo, Nd: YAG) - Laser: coherent, monochromatic, collimated (ruby, alexandrite, diode, Nd: YAG)
- IPL: no-coherente, policromática, no colimada (Intense Pulsed Light, lámparas de xenón con filtros paso-largo de diferentes longitudes de onda de corte entre 590 y 1200nm). - IPL: non-coherent, polychromatic, not collimated (Intense Pulsed Light, xenon lamps with long-pass filters of different wavelengths of cut between 590 and 1200nm).
El hecho de que la luz láser sea monocromática (sólo emite en una longitud de onda) hace que tenga un efecto selectivo en su aplicación sobre un tejido y, según diferentes estudios, la hace idónea para tratamientos de eliminación de vello en diferentes tipos de pieles. Los sistemas IPL emiten en una banda más ancha de longitudes de onda, haciendo el tratamiento menos efectivo y más arriesgado para personas de piel oscura. The fact that the laser light is monochromatic (only emits in a wavelength) makes it have a selective effect on its application on a tissue and, according to different studies, makes it ideal for hair removal treatments on different types of skin . IPL systems emit in a wider band of wavelengths, making treatment less effective and riskier for dark skinned people.
Por otra parte, la aplicación de luz sobre la piel puede destruir los folículos pilosos de tres formas distintas: térmica (por calentamiento local), mecánica (por ondas de choque o cavitación violenta) y química (por generación de compuestos tóxicos), todas ellas pueden encontrarse en la literatura y han sido estudiadas para la depilación. Según los estudios revisados, el sistema más efectivo y con menos riesgos es el efecto fototérmico, también llamado fototermólisis selectiva, proceso mediante el cual la transferencia de la energía láser se restringe a un lugar particular debido a la absorción selectiva de un cromóforo en ese lugar concreto. Esto significa que mediante la elección de la longitud de onda y el tiempo de exposición sólo dañamos el objetivo elegido. On the other hand, the application of light on the skin can destroy the hair follicles in three different ways: thermal (by local heating), mechanical (by shock waves or violent cavitation) and chemical (by generation of toxic compounds), all of them They can be found in the literature and have been studied for hair removal. According to the studies reviewed, the most effective and least risky system is the photothermal effect, also called selective photothermolysis, a process by which the transfer of laser energy is restricted to a particular place due to the selective absorption of a chromophore in that place. concrete. This means that by choosing the wavelength and exposure time we only damage the chosen target.
Asimismo, hay que tener en cuenta que la eficacia de la depilación láser depende mucho del fenotipo de piel individual, el color concreto del pelo, tipo o textura del pelo, densidad, factores hormonales y localización anatómica, aunque parece demostrado que todos los sistemas láser reducen temporalmente el crecimiento del pelo de todos los tipos de color (excepto las canas), existiendo, sin embargo, una estrecha relación entre el color del pelo y el flujo luminoso usado en la permanencia de la depilación. Also, it should be borne in mind that the effectiveness of laser hair removal depends a lot on the individual skin phenotype, the specific color of the hair, type or texture of the hair, density, hormonal factors and anatomical location, although It seems that all laser systems temporarily reduce hair growth of all types of color (except gray hair), however, there is a close relationship between hair color and the luminous flux used in the permanent hair removal.
Actualmente, los láseres más frecuentemente usados para equipos portátiles de depilación láser son los láseres de semiconductor (diodos láser) de 500mW a 808nm con óptica de enfoque, ya que su longitud de onda permite una buena profundidad de penetración y absorción de la melanina del folículo, además, la actual tecnología permite disponer de diodos de gran potencia, lo que permite tener un área grande de salida del haz para acelerar el tratamiento, permite disponer de diodos láseres a diferentes longitudes de onda para cubrir un mayor rango de tipos de pelo y pieles, siendo un sistema muy compacto que tiene muy poco consumo energético. Currently, the most frequently used lasers for portable laser hair removal equipment are semiconductor lasers (laser diodes) from 500mW to 808nm with focusing optics, since their wavelength allows a good depth of penetration and absorption of follicle melanin In addition, the current technology allows to have diodes of great power, which allows to have a large area of output of the beam to accelerate the treatment, allows to have laser diodes at different wavelengths to cover a greater range of hair types and skins, being a very compact system that has very little energy consumption.

Según esta publicación, los componentes lipidíeos del sebo (contenido en el folículo y la cubierta del cabello) absorben muy bien estas longitudes de onda, produciendo calor y daño por conducción de este calor a la papila, donde los vasos sanguíneos y el tejido alrededor de la papila se coagulan, impidiendo así que el pelo vuelva a crecer. La dosis sugerida en esta patente es bastante pequeña para producir efectos duraderos además de que el pelo es poco conductor térmico, de forma que las pérdidas radiativas antes de que la luz llegue a la papila son grandes reduciendo la eficacia del aparato. - WO99 / 60937 25mW laser pulsed 0.1 s in near infrared (900-1300nm) with 1 cm penetration and transported through an optical fiber. According to this publication, the lipid components of the sebum (contained in the follicle and the hair cover) absorb these wavelengths very well, producing heat and damage by conduction of this heat to the papilla, where the blood vessels and the tissue around The papilla coagulate, preventing the hair from growing again. The dose suggested in this patent is quite small to produce lasting effects in addition to the fact that the hair is poorly conductive, so that the radiative losses before the light reaches the papillae are large, reducing the effectiveness of the apparatus.
- US6168589 Reivindica el uso de cualquier fuente coherente de luz (láser) entre 694 y 900 nm para depilación, con un sistema de tratamiento de dos o más pulsos largos (2-30 ms) de alta potencia (10-40 J/cm2) separados por un periodo de 10-30 ms y un tamaño de spot mayor o igual que 10mm. La luz generada por el láser es transportada hasta la superficie de la piel vía fibra óptica, lo que modifica el perfil de irradiancia de la zona tratada. Esta patente propone un aparato que debe ser manipulado por un operario/a, sin ningún tipo de sensor de contacto y con diferentes opciones de funcionamiento que deben ser ajustables dependiendo del tipo de piel/pelo del paciente, lo que dificulta su entendimiento y su extrapolación para un uso en el hogar. - US6168589 Claims the use of any coherent source of light (laser) between 694 and 900 nm for hair removal, with a treatment system of two or more long pulses (2-30 ms) of high power (10-40 J / cm 2 ) separated by a period of 10-30 ms and a spot size greater than or equal to 10mm. The light generated by the laser is transported to the surface of the skin via fiber optics, which modifies the irradiance profile of the treated area. This patent proposes an apparatus that must be manipulated by an operator, without any contact sensor and with different operating options that must be adjustable depending on the type of skin / hair of the patient, which makes it difficult to understand and extrapolate For home use.
- WO01/45795 Utiliza un mínimo de 5 fuentes láser enfocadas sobre un mismo punto, que es conducido a través de un cilindro difusor hasta la superficie de la piel. La patente reclama que este método no resulta dañino de ninguna manera para la superficie de la piel, pero lo que no indica es que difícilmente puede aprovecharse las cualidades de penetración y concentración de energía de la luz láser haciéndola pasar a través de un difusor y rompiendo su coherencia espacial. Este proceso implica además el uso de láseres más potentes, con el consiguiente encarecimiento del producto final. - WO01 / 45795 It uses a minimum of 5 laser sources focused on the same point, which is conducted through a diffuser cylinder to the surface of the skin. The patent claims that this method is not harmful in any way to the surface of the skin, but what it does not indicate is that it is difficult to take advantage of the penetration and energy concentration qualities of the laser light by passing it through a diffuser and breaking Its spatial coherence. This process also implies the use of more powerful lasers, with the consequent increase in the price of the final product.
- WO02/09631 1 Sistema de protección para la aplicación de luz láseres para depilación, basado en un sistema mecánico alargador-replegador, mediante el cual es difícil que el cabezal aplicador se ponga en marcha si no es intencionalmente. También incluye una propuesta de secuencia pre-programada para el tratamiento depilatorio láseres, muy amplio y ambiguo para que comprenda todos los láseres, tamaños de pulso y periodos posibles. El diseño del sistema de seguridad es complejo y costoso a la hora de implementarlo en producción en serie, y no abarca sistemas portátiles, sino únicamente a la zona aplicadora (un tubo difusor que reduce la potencia final del láser) que no es el láser en sí. - WO02 / 09631 1 Protection system for the application of laser light for hair removal, based on a mechanical extension-refolding system, whereby it is difficult for the applicator head to start if it is not intentionally. It also includes a proposal for a pre-programmed sequence for laser hair removal treatment, very broad and ambiguous for you to understand all lasers, pulse sizes and possible periods. The design of the security system is complex and expensive when implementing it in series production, and does not cover portable systems, but only to the applicator zone (a diffuser tube that reduces the final power of the laser) that is not the laser in yes.
US6632218 Sistema que contiene un láser de alexandrita con una fibra óptica que lleva la luz láser generada hacia la superficie de la piel con la apertura de la fibra óptica. Utiliza pulsos mayores de 1 ms para el tratamiento, fluencias de 10-50 J/cm2, así como una solución tópica para marcar los puntos a tratar sobre la epidermis y para evitar reflexiones dañinas en la misma. El sistema propuesto es bastante aparatoso, poco portable y definitivamente ha de ser manejado por un profesional. No tiene ningún sistema de control de seguridad y utiliza un láser de alexandrita que es uno de los sistemas menos eficientes para esta aplicación. US6632218 System containing a alexandrite laser with an optical fiber that carries the laser light generated towards the surface of the skin with the opening of the optical fiber. It uses pulses greater than 1 ms for the treatment, fluences of 10-50 J / cm2, as well as a topical solution to mark the points to be treated on the epidermis and to avoid harmful reflections on it. The proposed system is quite cumbersome, not very portable and must definitely be handled by a professional. It has no safety control system and uses a alexandrite laser that is one of the least efficient systems for this application.

Exposición de medidas experimentales realizadas con 62 usuarios en las que se establece una correlación entre tipo de piel según la escala Fitzpatrick y la dosis del láser. Patente técnica donde se reivindica el método de aplicación más que un producto en concreto.

US2005/0256514 Propone el uso de al menos 5 paquetes (de duración 0-5 a 10 ms) de pulsos (de ns de tamaño) en la administración de la dosis (2 a 60 J/cm2), en lugar de depositar la dosis total en un solo pulso para evitar daños en la piel. US2005 / 0256514 Proposes the use of at least 5 packages (of duration 0-5 to 10 ms) of pulses (of size ns) in the administration of the dose (2 to 60 J / cm 2 ), instead of depositing the Total dose in a single pulse to avoid skin damage.
PCT/ES2007/800142 Patente del primer diseño del Shinepil conteniendo un único láser de diodo de 808nm y un LED azul, sin sistema de seguridad que haga el aparato de clase I ni posibilidad de depilación de vello más claro. PCT / ES2007 / 800142 Patent of the first design of the Shinepil containing a single 808nm diode laser and a blue LED, without safety system that makes the class I device or possibility of lighter hair removal.
WO2007/034161 Esta es la patente del depilador conocido como Riolaser y que se comercializa también con otras marcas. Este sistema se orienta al sector doméstico, y contiene un sensor de seguridad que lo clasifica cono clase I, sin embargo no es portátil, ya que contiene una mesa de control y un cabezal (tipo teléfono) que lleva el aplicador. WO2007 / 034161 This is the patent of the epilator known as Riolaser and is also marketed under other brands. This system is oriented to domestic sector, and contains a safety sensor that classifies it as a class I cone, however it is not portable, since it contains a control table and a head (telephone type) that the applicator carries.
US7250045 Patente donde se propone un aparato ligero (<1 kg) sin cable y el uso de un difusor óptico a la salida del haz, para evitar la posibilidad de que el láser produzca daño ocular, así como la inclusión de un sensor de contacto. Por la variación de la potencia de un láser de diodo frente al uso (desgaste de la batería), la potencia disminuye muy rápido y, por tanto, la portabilidad de equipos basados en alimentación por baterías no es realista. Por otro lado, y como hemos visto anteriormente, colocar un difusor óptico a la salida de un haz láser reduce su potencia, su focalización y destruye su coherencia espacial, lo que reduce su distancia de penetración en el tejido. US7250045 Patent which proposes a light device (<1 kg) without cable and the use of an optical diffuser at the beam exit, to avoid the possibility of the laser causing eye damage, as well as the inclusion of a contact sensor. Due to the variation of the power of a diode laser against use (battery wear), the power decreases very fast and, therefore, the portability of equipment based on battery power is not realistic. On the other hand, and as we have seen before, placing an optical diffuser at the exit of a laser beam reduces its power, its focus and destroys its spatial coherence, which reduces its distance of penetration into the tissue.
US7329252 Propone un sistema con láser de semiconductor emitiendo en alguna longitud de onda entre 600 y 1600nm con potencias entre 5 y 1500 mW, que incluye un sistema que puede expulsar aire (refrigeación) o absorberlo (acercando la zona a tratar al punto de emisión láser). US7329252 Proposes a semiconductor laser system emitting at some wavelength between 600 and 1600nm with powers between 5 and 1500 mW, which includes a system that can expel air (cooling) or absorb it (bringing the area to be treated closer to the laser emission point ).
Se constata, pues, que coexisten en el mercado múltiples tipos de aparatos y dispositivos para la depilación por láser, los cuales, sin embargo, en la mayoría de los casos consisten en complejos y costosos equipos encaminados a un uso profesional debiendo ser manejados por personal experimentado o, en el caso de alguno que sea de carácter portátil, teniendo un rango de aplicación muy limitado que restringe en gran medida el abanico de público al que puede estar dirigido, que además no presentan una óptima eficacia en los resultados obtenidos. Therefore, it is found that multiple types of devices and devices for laser hair removal coexist in the market, which, however, in most cases consist of complex and expensive equipment for professional use and must be handled by personnel experienced or, in the case of one that is portable in nature, having a very limited range of application that greatly restricts the range of audiences to which it may be directed, which also does not have an optimum efficiency in the results obtained.
Se puede afirmar, pues, que por parte del solicitante no se ha encontrado ningún otro aparato depilador láser portátil de uso polivalente ni que presente unas características técnicas, estructurales y constitutivas semejantes a las que presenta el aquí preconizado, estando los detalles caracterizado res que lo distinguen adecuadamente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva. EXPLICACIÓN DE LA INVENCIÓN It can be affirmed, therefore, that no other portable laser hair removal device for multipurpose use has been found on the part of the applicant, nor that it has technical, structural and constitutive characteristics similar to those presented here, with the details characterized as being distinguish properly set out in the final claims that accompany the present specification. EXPLANATION OF THE INVENTION
Así, el aparato depilador láser portátil de uso polivalente que la presente invención propone se configura como una destacable novedad dentro de su campo de aplicación, ya que, a tenor de su implementación y de forma taxativa, se alcanzan satisfactoriamente los objetivos de aportar al estado de la técnica un aparato portátil mejorado, de manejo sencillo apto para cualquier usuario, de bajo coste económico para ser accesible a todo tipo de público y apto para todo tipo de usuarios, independientemente del color de vello que tengan, el cual, además, proporciona un elevado nivel de efectividad en cuanto a los resultados en la depilación obtenida y, a la vez, se configura como totalmente seguro en uso. Thus, the versatile portable laser hair removal device that the present invention proposes is configured as a remarkable novelty within its field of application, since, in accordance with its implementation and in a restrictive manner, the objectives of contributing to the state are satisfactorily achieved of the technique an improved portable device, of simple handling suitable for any user, of low economic cost to be accessible to all types of public and suitable for all types of users, regardless of the hair color they have, which, in addition, provides a high level of effectiveness in terms of the results in the hair removal obtained and, at the same time, is configured as totally safe in use.
Para todo ello, y de manera concreta lo que la invención preconiza, pues, es un aparato depilador láser que, conformado a partir de una carcasa envolvente de configuración ergonómica apta para albergar en su interior todos los elementos funcionales del mismo con suficientes garantías de protección, comprende un sistema de iluminación de luz coherente láser que consiste en la iluminación directa de uno, dos o tres diodos láser, uno para piel y vello claro, otro para piel oliva y vello oscuro y un último para piel negra y vello oscuro de potencia media en rojo e infrarrojo cercano, respectivamente a través de una lente óptica de material acrílico y recubrimiento anti-reflejante que enfoca el láser en la apertura de salida del instrumento para su correcta aplicación. For all this, and specifically what the invention advocates, then, is a laser hair removal device that, formed from an enveloping shell of ergonomic configuration suitable to house inside all the functional elements thereof with sufficient protection guarantees , includes a coherent laser light lighting system consisting of the direct illumination of one, two or three laser diodes, one for skin and light hair, another for olive skin and dark hair and one for black skin and dark hair power medium in red and near infrared, respectively through an optical lens of acrylic material and anti-reflective coating that focuses the laser on the opening of the instrument for its correct application.
Es importante señalar que en el aparato propuesto no existen ventanas de protección más allá de la lente que va colocada muy cerca del láser, sólo una cúpula de posicionamiento transparente y con la longitud adecuada para facilitar la aplicación del láser sobre el vello a remover. It is important to note that in the proposed apparatus there are no protection windows beyond the lens that is placed very close to the laser, only a transparent positioning dome and with the appropriate length to facilitate the application of the laser on the hair to be removed.
El hecho de utilizar óptica con recubrimientos anti-reflejante, reduce al máximo las pérdidas por absorción, reflexión y dispersión en las superficies, y posibilita que los diodos láser estén más alejados del cuero cabelludo, aprovechando esta circunstancia para adaptar el tamaño de salida del haz a una potencia inferior. Dado que el uso de luz láser monocromática en el rango de 650 a 900 nm es el modo más efectivo de depilación permanente que se conoce el aparato preconizado contempla el uso de láseres de diodo (LD), que son fabricados con una buena cantidad de diferentes longitudes de onda de salida y son fácilmente controlables con precisión electrónica para emitir la dosis concreta requerida en cada caso. De esta manera, el equipo de depilación puede fabricarse con diferentes longitudes de onda de salida sin más que escoger otro diodo láser con diferente longitud de onda pero iguales condiciones electrónicas. The fact of using optics with anti-reflective coatings, minimizes losses by absorption, reflection and dispersion on the surfaces, and allows laser diodes to be further away from the scalp, taking advantage of this circumstance to adapt the output size of the beam at a lower power. Since the use of monochromatic laser light in the range of 650 to 900 nm is the most effective way of permanent hair removal known to the recommended apparatus contemplates the use of diode (LD) lasers, which are manufactured with a good amount of different Output wavelengths and are easily controllable with electronic precision to emit the specific dose required in each case. In this way, the hair removal equipment can be manufactured with different output wavelengths without choosing another laser diode with a different wavelength but with the same electronic conditions.
Los diodos láser escogidos tienen una buena relación calidad/economía de precio, sin embargo, emiten según una gran divergencia de haz. Esta última característica hace que la salida de cada haz láser sea elíptica, por lo que se contempla el uso de lentes para concentrar el haz en un área más conveniente. The chosen laser diodes have a good price / quality ratio, however, they emit according to a large beam divergence. This last feature makes the output of each laser beam elliptical, so the use of lenses to concentrate the beam in a more convenient area is contemplated.
En concreto, los citados diodos, preferentemente, serán: Specifically, said diodes, preferably, will be:
- para piel oliva y vello oscuro, de 500mw de potencia y 808nm de longitud de onda, con lente colimadora de focal 18mm y diámetro efectivo 4.37mm., tal como AlGaAs de Roithner Lasertechnik, - for olive skin and dark hair, of 500mw of power and 808nm of wavelength, with collimating lens of focal 18mm and effective diameter 4.37mm., such as AlGaAs of Roithner Lasertechnik,
- para piel clara y vello claro, de 50mw de potencia y 685nm de longitud de onda, con lente colimadora de focal 18mm y diámetro efectivo 4.37mm., tal como InGaAIP de Roithner Lasertechnik. - for light skin and light hair, 50mw of power and 685nm of wavelength, with 18mm focal collimator lens and 4.37mm effective diameter, such as Roithner Lasertechnik's InGaAIP.
- y para piel negra y vello oscuro, de 500mW de potencia y 1064nm de longitud de onda, con lente colimadora de focal 18mm y diámetro efectivo 4.37mm, tal como AlGaAs de Roithner Lasertechnik. - and for black skin and dark hair, of 500mW of power and 1064nm of wavelength, with collimator lens of focal 18mm and effective diameter 4.37mm, such as AlGaAs of Roithner Lasertechnik.
Lógicamente, dado que se incluyen uno, dos o tres láseres de diodo a tres diferentes longitudes de onda para tres tipos de piel/pelo diferentes, con diferentes potencias y aperturas, cada uno deberá ir pulsado con diferente periodo (tiempo entre pulsos) y diferente tamaño de pulso. Como ejemplo, en el caso del equipo con dos salidas, los dos láseres están situados a una distancia de 36,76mm de la apertura (elíptica de ejes mayor y menor 4mm y 3mm, respectivamente) y cada láser está separado de la vertical 95 (185 entre los dos láseres). A esta distancia, y dada la salida elíptica del láser, conviene utilizar la citada lente colimadora para láser de focal 18mm y diámetro efectivo 4.37mm que se ha apuntado anteriormente. Logically, since one, two or three diode lasers at three different wavelengths are included for three different skin / hair types, with different powers and openings, each one must be pressed with different period (time between pulses) and different pulse size As an example, in the case of the device with two outputs, the two lasers are located at a distance of 36.76mm from the opening (elliptic of major and minor axes 4mm and 3mm, respectively) and each laser is separated from the vertical 9 5 (18 5 between the two lasers). At this distance, and given the elliptical output of the laser, it is convenient to use the aforementioned collimator lens for 18mm focal laser and effective diameter 4.37mm that has been pointed out above.
El aparato de depilación basado en luz láser preconizado se ha diseñado para que exista una fuerte absorción por la melanina y una penetración profunda en los tejidos, por lo que se configura como un sistema susceptible de producir lesiones en la retina. Debido a ese riesgo de lesión ocular, se contempla la utilización de un sensor de contacto que evita el encendido de los diodos láser en posiciones que no sean las del tratamiento, haciendo con ello que el instrumento pase a ser clasificado como de Clase I según la norma de calidad UNE-EN-60825- 1 , es decir, seguro en todas las condiciones razonablemente previsibles, lo que permite considerar el instrumento como de uso habitual en el hogar. The hair removal device based on recommended laser light has been designed so that there is a strong absorption by melanin and a deep penetration into the tissues, so it is configured as a system capable of causing retinal lesions. Due to this risk of ocular injury, the use of a contact sensor that prevents the ignition of the laser diodes in positions other than those of the treatment is contemplated, thereby making the instrument become classified as Class I according to the quality standard UNE-EN-60825-1, that is, safe in all reasonably foreseeable conditions, which allows the instrument to be considered as usual for use in the home.
Este sistema no altera las especificaciones de la iluminación láser (coherencia espacial y temporal, apertura, potencia), sino sólo el momento en que se aplica, a diferencia de la opción alternativa utilizada en otros aparatos conocidos en el mercado, y que consiste en la colocación de un difusor delante de la salida del haz láser que hace que se rompa la coherencia espacial del láser y se elimine su peligrosidad. This system does not alter the specifications of the laser lighting (spatial and temporal coherence, aperture, power), but only the moment in which it is applied, unlike the alternative option used in other devices known in the market, and which consists of the Placing a diffuser in front of the laser beam outlet that causes the spatial coherence of the laser to be broken and its danger eliminated.
Dicho sistema, sin embargo, presenta el inconveniente de que modifica la coherencia espacial de haz láser, de forma que reduce su penetración en los tejidos, siendo necesario entonces aumentar la potencia base del láser (aumentando el costo del sistema), modifica también la apertura del haz láser haciéndolo de mayor diámetro, de forma que también se reduce la dosis efectiva sobre los tejidos, siendo necesario utilizar un láser de mayor potencia, y modifica la potencia de salida del haz, puesto que al ser un elemento refractivo, la luz tiene que pasar a través del difusor, el cual siempre absorbe y refleja parte de la luz incidente. Said system, however, has the disadvantage that it modifies the spatial coherence of the laser beam, so that it reduces its penetration into the tissues, then it is necessary to increase the base power of the laser (increasing the cost of the system), it also modifies the aperture of the laser beam making it of greater diameter, so that the effective dose on the tissues is also reduced, being necessary to use a laser of greater power, and modifies the output power of the beam, since being a refractive element, the light has to pass through the diffuser, which always absorbs and reflects part of the incident light.
Siguiendo con la invención, hay que destacar que el aparato cuenta con un sistema de accionamiento a base de botones de contacto o "touch controí' (TC), en lugar de botones mecánicos o de membrana de uso más convencional, el cual, como es sabido, se basa en el fenómeno físico de la variación de la carga de un condensador por efecto de la carga eléctrica del cuerpo humano. Following the invention, it should be noted that the device has with a drive system based on contact buttons or "touch control" (TC), instead of mechanical or membrane buttons of more conventional use, which, as is known, is based on the physical phenomenon of the variation of the charge of a capacitor due to the electric charge of the human body.
Debe señalarse que la configuración estructural del aparato influye en la forma de trabajar del TC ya que indica en la sensibilidad con la que el dispositivo tendrá que trabajar. El electrodo es el elemento electrónico del sistema que más depende del diseño del instrumento. It should be noted that the structural configuration of the device influences the way the CT works as it indicates the sensitivity with which the device will have to work. The electrode is the electronic element of the system that most depends on the design of the instrument.
Así, el tamaño del electrodo del TC debe guardar una proporción media definida por su dimensión más pequeña de 4 a 1 respecto de la distancia del mismo al punto de contacto del dedo con la superficie del aparato, pudiendo tomar multitud de formas (plano circular, plano rectangular, tipo muelle...). Thus, the size of the CT electrode must keep an average proportion defined by its smallest dimension of 4 to 1 with respect to the distance of the same to the point of contact of the finger with the surface of the device, being able to take many forms (circular plane rectangular plane, spring type ...).
Respecto al funcionamiento del instrumento, hay que decir que es muy sencillo, conteniendo sólo dos posiciones pulsadoras, aunque el sensor de contacto actúa como un tercer pulsador (automático del láser) cuando detecta que el instrumento está posicionado sobre piel/cuero cabelludo. Regarding the operation of the instrument, it must be said that it is very simple, containing only two push-button positions, although the contact sensor acts as a third push-button (automatic laser) when it detects that the instrument is positioned on skin / scalp.
Dependiendo del número de láseres que incluya el equipo según su modelo, pueden darse diversas opciones de funcionamiento, como por ejemplo las siguientes: Depending on the number of lasers included in the equipment according to your model, various operating options may occur, such as the following:
- Un láser: encendido del láser, apagado del láser. - A laser: laser on, laser off.
- Dos láseres: en todas las combinaciones que permitan los de tipo (a) 685nm, (b) 808nm y (c) 1064nm. - Two lasers: in all combinations that allow type (a) 685nm, (b) 808nm and (c) 1064nm.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN A la vista de las mencionadas figuras, y de acuerdo con la numeración adoptada, se puede observar en ellas un ejemplo de realización preferente de la invención, la cual comprende las partes y elementos que se indican y describen en detalle a continuación. PREFERRED EMBODIMENT OF THE INVENTION In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.
Así, tal como se observa en dichas figuras, el aparato de ejemplo correspondiente al modelo con dos láseres(1 ) en cuestión está conformado a partir de una carcasa (2) de configuración ergonomica, aproximadamente alargada, cuya parte delantera se prolonga en un cabezal (1 1 ) cubierto por una cúpula transparente (3), dotada de un orificio (4) en su parte inferior, y en cuyo interior alberga un sistema de iluminación de láser constituido por dos diodos (5, 6) láser, de diferentes longitudes de onda, potencia y apertura, cada uno pulsado con diferente periodo (tiempo entre pulsos) y diferente tamaño de pulso, que están optimizados uno para vello oscuro (5) y otro para vello claro (6) de potencia media en rojo e infrarrojo, respectivamente, a través de una lente óptica (7) de material acrílico y recubrimiento anti-reflejante que enfoca el láser en el orificio (4) del extremo inferior del cabezal (1 1 ). Thus, as seen in said figures, the example apparatus corresponding to the model with two lasers (1) in question is formed from a casing (2) of ergonomic configuration, approximately elongated, whose front part is extended in a head (1 1) covered by a transparent dome (3), equipped with a hole (4) in its lower part, and inside which houses a laser lighting system consisting of two laser diodes (5, 6), of different lengths wave, power and opening, each pulsed with different period (time between pulses) and different pulse size, which are optimized one for dark hair (5) and another for light hair (6) of medium power in red and infrared, respectively, through an optical lens (7) of acrylic material and anti-reflective coating that focuses the laser in the hole (4) of the lower end of the head (1 1).
En este ejemplo concreto, los citados diodos, preferentemente, serán: In this specific example, said diodes, preferably, will be:
- para vello oscuro (5), un diodo de 500mw de potencia y 808nm de longitud de onda, con lente (7) colimadora de focal 18mm y diámetro efectivo 4.37mm. - for dark hair (5), a diode of 500mw of power and 808nm of wavelength, with lens (7) collimator of focal 18mm and effective diameter 4.37mm.
- y para vello claro (6), de 50mw de potencia y 685nm de longitud de onda, con lente (7) colimadora de focal 18mm y diámetro efectivo 4.37mm.. - and for light hair (6), of 50mw of power and 685nm of wavelength, with lens (7) collimator of focal 18mm and effective diameter 4.37mm ..
Además, tal como se aprecia en la figura 4, los dos láseres, es decir, el conjunto de diodos (5,6) y correspondientes lentes (7), están situados a una distancia (d) de 36,76mm de la apertura u orificio (4) y cada láser está separado del eje vertical (8) 95, existiendo una distancia entre ambos de 185. A esta distancia, y dada la salida elíptica del láser, conviene utilizar una lente (7) colimadora para láser de focal 18mm y diámetro efectivo 4.37mm apuntada anteriormente. El aparato, en orden a evitar una eventual lesión ocular, incorpora un sensor resistivo de contacto (9) que evita el encendido de los diodos láser (5,6) en posiciones que no sean las del tratamiento, para lo cual está calibrado para que detecte piel siendo capaz de diferenciarla de otros materiales, siendo, preferentemente un sensor de diseño específico para que sea lo más pequeño y económico posible. In addition, as shown in Figure 4, the two lasers, that is, the set of diodes (5.6) and corresponding lenses (7), are located at a distance (d) of 36.76mm from the aperture u hole (4) and each laser is separated from the vertical axis (8) 9 5 , there being a distance between them of 18 5 . At this distance, and given the elliptical output of the laser, it is convenient to use a collimator lens (7) for 18mm focal laser and effective diameter 4.37mm noted above. The device, in order to avoid an eventual eye injury, incorporates a resistive contact sensor (9) that prevents the ignition of the laser diodes (5,6) in positions other than those of the treatment, for which it is calibrated so that detect skin being able to differentiate it from other materials, being preferably a sensor of specific design to be as small and economical as possible.
Finalmente, el aparato cuenta con un sistema de accionamiento a base de botones de contacto (10) tipo "touch control", y que comprende un electrodo un chip de detección una lógica de interpretación, resistencias, condensadores y cableado, siendo el electrodo de una dimensión más pequeña de 4 a 1 respecto de la distancia del mismo al botón de contacto (10) en la superficie del aparato, botón que puede tomar multitud de formas (plano circular, plano rectangular, tipo muelle...). Finally, the device has an actuation system based on contact buttons (10) type "touch control", and which comprises an electrode a detection chip an interpretation logic, resistors, capacitors and wiring, the electrode being a Smaller dimension of 4 to 1 with respect to the distance of the same from the contact button (10) on the surface of the device, a button that can take many forms (circular plane, rectangular plane, spring type ...).
Tal como se ha señalado en párrafos anteriores, el funcionamiento de este ejemplo de aparato correspondiente al modelo con dos láseres es muy sencillo comprendiendo dos posiciones pulsadoras, con correspondientes botones de contacto, uno para el diodo de vello oscuro (10a) y otro para el de vello claro (10b) y un lanzador de disparo (10c), actuando el sensor de contacto (9) como un tercer pulsador automático del láser cuando detecta que el instrumento está posicionado sobre piel/cuero cabelludo. As indicated in previous paragraphs, the operation of this example of an apparatus corresponding to the model with two lasers is very simple comprising two push-button positions, with corresponding contact buttons, one for the dark hair diode (10a) and another for the with light hair (10b) and a shot launcher (10c), the contact sensor (9) acting as a third automatic laser button when it detects that the instrument is positioned on skin / scalp.
Así, Al pulsar el botón de contacto de vello oscuro (10a), el diodo de vello oscuro (5) de 808nm se conecta pero no se enciende. Thus, when the dark hair contact button (10a) is pressed, the dark hair diode (5) of 808nm is connected but does not light.
Al posicionar el cabezal (1 1 ) sobre la zona a tratar, el sensor de contacto (9) detecta la piel/cuero cabelludo y el láser se prepara para emitir.  By positioning the head (1 1) on the area to be treated, the contact sensor (9) detects the skin / scalp and the laser prepares to emit.
Al pulsar el botón de contacto del lanzador de disparo (10c) el láser seleccionado comienza a emitir. When the contact button of the firing launcher (10c) is pressed, the selected laser starts to emit.
Al pulsar el botón de contacto de vello claro (10b), el diodo de vello claro (6) de 685nm se conecta pero no se enciende. Y al posicionar el cabezal (1 1 ) sobre la zona a tratar, el sensor de contacto (9) detecta la piel/cuero cabelludo y el láser se prepara para emitir. When the light hair contact button (10b) is pressed, the light hair diode (6) of 685nm is connected but does not light. And by positioning the head (1 1) on the area to be treated, the contact sensor (9) detects the skin / scalp and the Laser prepares to emit.
Al pulsar el botón de contacto del lanzador de disparo (10c) el láser seleccionado comienza a emitir. When the contact button of the firing launcher (10c) is pressed, the selected laser starts to emit.
Así pues, los láseres sólo se ponen en funcionamiento cuando el aparato está encendido, el sensor de contacto detecta que el instrumento está posicionado sobre piel o cuero cabelludo y se presiona el lanzador. Thus, lasers are only put into operation when the device is on, the contact sensor detects that the instrument is positioned on skin or scalp and the launcher is pressed.
