Description

CAPACETE DE LED COM TRANSPORTADOR DE LUZ DO DIODO PARA O COURO  LED HELMET WITH LEATHER DIODE CONVERTER FOR LEATHER
CABELUDO HAIRY
CAMPO DE APLICAÇÃO APPLICATION FIELD
[001] O presente pedido de patente se refere a um capacete dotado internamente com estruturas transportadoras de luz (light transporters) garantindo a entrega eficaz da luz do diodo direto ao couro cabeludo e proporcionando eficiência na entrega da exposição radiante diretamente no folículo capilar e, consequentemente, no tratamento capilar. Os díodos emissores de luz (LED) são estruturados em formato de espículas transmissoras de luz.  The present application relates to a helmet internally provided with light transporters ensuring the effective delivery of light from the diode directly to the scalp and providing efficiency in the delivery of radiant exposure directly into the hair follicle and, consequently, in hair treatment. The light emitting diodes (LEDs) are structured in the shape of light transmitting spicules.
[002] Assim, a presente invenção trata de um capacete com espículas que podem ser revestidas tanto por um material metálico quanto resinado.  Thus, the present invention relates to a helmet with spikes which can be coated by both a metallic and a resinstock.
[003] O material da espícula é considerado um ótimo transmissor de luz e, neste caso, transportará a luz do diodo até o couro cabeludo transpondo estruturas como os cabelos. A espícula não deixa que a luz escape lateralmente direcionando o transporte da luz do diodo diretamente ao couro cabeludo.  The spike material is considered a good light transmitter and in this case will carry the light from the diode to the scalp transposing structures such as the hair. The spike does not allow the light to escape laterally by directing the transport of diode light directly to the scalp.
[004] Estruturas como o cabelo podem absorver a luz com comprimentos de onda na faixa do espectro eletromagnético na região da luz visível e/ou infravermelho e fazer com que a energia do dispositivo que chega no couro cabeludo, mais especificamente no folículo capilar, seja menor do que o necessário para ocorrer efetivamente o fenómeno de fotobiomodulação.  Structures such as hair can absorb light with wavelengths in the range of the electromagnetic spectrum in the region of visible and / or infrared light and cause the energy of the device arriving in the scalp, more specifically in the hair follicle, to be smaller than necessary to effectively produce the photobiomodulation phenomenon.
ESTADO DA TÉCNICA STATE OF THE TECHNIQUE
[005] Atualmente, é possível encontrar no mercado alguns dispositivos voltados a implementação de tais características no couro cabeludo. No entanto, nenhum dos dispositivos citados nas instituições defensoras de patentes é semelhante ao capacete de LED com transportador de luz do diodo ao couro cabeludo.  [005] Currently, it is possible to find in the market some devices aimed at the implementation of such characteristics in the scalp. However, none of the devices cited in the patent defending institutions is similar to the LED light-carrying diode-to-scalp light helmet.
[006] Dentre os documentos encontrados no Estado da Técnica podemos citar o US7722656B1, publicado em 25/05/2010 que descreve um dispositivo e método para estimulação de crescimento de cabelo (Device and Method for Stimulating Hair Growth) que compreende uma ou mais fontes de diodo laser em que cada uma delas está operando em baixa voltagem (menos que 1.000 mW) no espectro do infravermelho de 2.500 nm até cerca de 10.000 nm e potência com cerca de 500 mW. Este dispositivo apresenta díodos arranjados em espaçamentos fixos em torno do couro cabeludo que se movem seguindo ciclos periódicos dentro de um certo período de tempo. Trata-se de um método de aplicação rotacional seguindo um padrão de dispersão do diodo em certas áreas pelo menos uma vez durante o ciclo periódico. A despeito da versatilidade de tratamentos que podem ser realizados por este equipamento, o mesmo não apresenta contato da fonte de luz até o couro cabeludo o que acaba por não garantir a dose efetiva do dispositivo até o folículo capilar já que outras estruturas poderão absorver parte da energia do emissor de luz. Além do mais, é feito de laser e os ciclos periódicos não garantem atingir toda a região do couro cabeludo como no caso das cinco regiões mais afetadas pela alopecia. Among the documents found in the Prior Art, we can cite US7722656B1, published on 05/25/2010 which describes a device and method for hair growth stimulation (Device and Method for Stimulating Hair Growth) comprising one or more sources (less than 1,000 mW) in the infrared spectrum from 2500 nm to about 10,000 nm and power of about 500 mW. This device features diodes arranged at fixed spacings around the scalp that move following periodic cycles within a certain period of time. It is a rotational application method following a pattern of dispersion of the diode in certain areas at least once during the periodic cycle. Despite the versatility of treatments that can be performed by this equipment, it does not present contact of the light source to the scalp which ends up not guaranteeing the effective dose of the device to the hair follicle since other structures can absorb part of the energy of the light emitter. Moreover, it is made of laser and the periodic cycles do not guarantee to reach the entire region of the scalp as in the case of the five regions most affected by alopecia.
[007] Quanto ao documento ES2522165T3, publicado em 13/11/2014, trata-se de um dispositivo portátil de fototerapia para tratamento do couro cabeludo permitindo " hands-fred' durante a aplicação. O dispositivo apresenta um suporte para cabeça com matriz de fontes de luz, molas para adequar o dispositivo em diversos formatos de cabeça e um controlador. Este dispositivo diz ser de fácil utilização, apresenta programações de tratamento específicos variando para homem ou mulher com cerca de 20 a 25 minutos de duração e promete cobrir áreas específicas do couro cabeludo. Porém, como no caso anterior, o mesmo não apresenta contato da fonte de luz até o couro cabeludo o que acaba por não garantir a exposição radiante efetiva do dispositivo já que estruturas como o cabelo, absorverá parte da energia do emissor de luz e ainda apresenta cerca de no máximo 30 emissores de luz o que é considerada uma quantidade sem capacidade de haver homogeneidade durante o processo de irradiação da área tratada e também atingir as cinco regiões mais afetadas pela alopecia.  As regards document ES2522165T3, published 11/13/2014, it is a portable phototherapy device for treating the scalp allowing "hands-fred" during the application. The device features a head support with light sources, springs to fit the device into a variety of head shapes and a controller.This device claims to be easy to use, has specific treatment schedules ranging for men or women ranging from about 20 to 25 minutes in length and promises to cover specific areas However, as in the previous case, it does not present contact of the light source to the scalp which ends up not guaranteeing the effective radiant exposure of the device since structures such as the hair, will absorb part of the energy of the emitter light and still presents about 30 light emitters, which is considered an amount that can not be homogeneous during the irr process treatment and also reach the five regions most affected by alopecia.
[008] Outro dispositivo, o JP2006116088A, publicado em 11/05/2006, consiste em ser um aparato de laser capaz de irradiar na superfície da pele. Se diz ser de simples configuração e apresenta a capacidade de proporcionar diferentes tipos de contato por distanciar ou aproximar as lentes do laser e, através disso, controlar a exposição radiante no tecido em um menor tempo de uso. Por ser composto por laser e lentes, este dispositivo tende a apresentar um custo elevado e não é possível irradiar homogeneamente todo o couro cabeludo de maneira a tratar as 5 regiões mais afetadas pela alopecia.  Another device, JP2006116088A, issued 05/05/2006, is to be a laser apparatus capable of irradiating on the surface of the skin. It is said to be simple in configuration and has the ability to provide different types of contact by distancing or approaching the lenses of the laser and thereby controlling the radiant exposure in the tissue in a shorter time of use. Because it consists of laser and lenses, this device tends to present a high cost and it is not possible to irradiate homogeneously throughout the scalp in order to treat the 5 regions most affected by alopecia.
[009] Já o documento KR20080025989A publicado em 24/03/2008 faz referência a um equipamento para crescimento de cabelo com infravermelho formado por um corpo principal em forma de capacete, uma capa de silicone, vários díodos alocados nesta capa de silicone com comprimento de onda entre 650~890 nm em projeções simulando os pontos de acupuntura, uma fonte de alimentação, um controlador com painel de exibição em LCD e um interruptor. Como o dispositivo anterior, também não irradia homogeneamente todo o couro cabeludo de maneira a tratar as 5 regiões mais afetadas pela alopecia. Além de não mencionar o tempo de aplicação e não proporcionar eficácia no transporte da luz diretamente no folículo capilar. Vale ressaltar ainda que o silicone tem tendência de amarelar conforme o tempo de utilização, o que acaba por bloquear parte da luz a ser irradiada. Already the document KR20080025989A published on 03/24/2008 refers to an equipment for hair growth with infrared formed by a main body in the form of a helmet, a cover of silicone, several diodes allocated in this layer of silicone with length of between 650 ~ 890 nm in projections simulating the acupuncture points, a power supply, a controller with LCD display panel and a switch. Like the previous device, it also does not radiate homogenously throughout the scalp in order to treat the 5 regions most affected by alopecia. In addition to not mentioning the application time and not providing efficacy in the transport of light directly into the hair follicle. It is worth mentioning that the silicone tends to yellow according to the time of use, which ends up blocking part of the light to be irradiated.
[010] Quanto ao transportador de luz, foram encontrados dispositivos como no caso do US12456750 publicado em 23/12/2010 e que descreve um transportador de luz visível composto por suportes para outros dispositivos como no caso de lâmpadas iluminadoras de estrada. Tal dispositivo é composto por resina que permite que a luz seja atenuada e transmitida. Este dispositivo não é aplicado à medicina além de ser composto por resina e, portanto, não se faz semelhante ao n//ght transportei' descrito neste documento. As to the light conveyor, devices have been found as in the case of US12456750 published on 12/23/2010 and which describes a visible light conveyor composed of supports for other devices as in the case of road lighting lamps. Such a device is composed of resin that allows the light to be attenuated and transmitted. This device is not applied to medicine besides being composed of resin, and therefore does not similar to ght transported n // 'described herein.
[011] Também podemos citar o GB 222.963, publicado em 13/10/1924 e que descreve um equipamento para o tratamento dos cabelos que compreende uma caixa apresentando uma abertura para a inserção da cabeça do usuário. Dentro da caixa do equipamento é previsto um gerador de ozônio por descarga elétrica de alta tensão e lâmpadas coloridas para o tratamento do cabelo (azul e vermelha). O equipamento compreende uma caixa retangular com a parte frontal inferior recortada. Os cabelos são jogados sobre uma parede inclinada. Uma bobina de indução, dentro de uma caixa, é ligada a eletrodos que se projetam para dentro da caixa. São previstos filamentos aquecidos eletricamente, lâmpadas vermelha e azul, cada uma delas sendo ligada através de uma chave independente, uma ventoinha, uma porta e um termómetro. A despeito da versatilidade de tratamentos que podem ser realizados por este equipamento, o mesmo apresenta uma grande dimensão, o que o torna incompatível com o uso doméstico.  We may also cite GB 222,963, issued 10/13/1924 and which describes a hair treatment apparatus which comprises a carton having an aperture for insertion of the user's head. Inside the box of the equipment is provided an ozone generator by electric discharge of high tension and colored lamps for the treatment of the hair (blue and red). The equipment comprises a rectangular box with the lower front cut out. The hairs are thrown over a slanted wall. An induction coil within a housing is attached to electrodes that project into the housing. Electrically heated filaments, red and blue lamps are provided, each of which is connected via an independent switch, a fan, a door and a thermometer. Despite the versatility of treatments that can be performed by this equipment, it has a large dimension, which makes it incompatible with domestic use.
[012] Dentro do escopo de se empregar um objeto de menor dimensão, e, portanto, passível de ser facilmente adquirido e utilizado pelo usuário, o estado da arte prevê, tal como descrito no documento CN1398650, publicado em 26/02/2003, uma escova de cabelos dotada de LEDs vermelhos para promover a melhora da circulação sanguínea, o crescimento dos cabelos e diminuir a coceira. No mesmo sentido, o PI 0704946-3 descreve uma escova de LED para tratamento de fototerapia no cabelo. Este tem por objetivo uma escova com díodos emissores de luz para tratamento de fototerapia no cabelo, tal como calvície, perda de cor e hidratação, com vistas a melhorar o bem-estar de vida e saúde dos indivíduos. O aparelho é composto de um módulo com 10 centímetros de largura, por 20 centímetros de comprimento, por 5 centímetros de altura. No módulo extremo da aplicação existe uma pequena escova, onde estão localizados 10 LEDs nas cores vermelha, com tamanho de onda de 650 nm, e azuis, com tamanho de onda de 405 nm. O aparelho ainda apresenta um botão para acionamento, e alimentação feita por baterias internas de lítio. O usuário deve ligar o aparelho e escovar ou pentear o cabelo, percorrendo todo o couro cabeludo. O tratamento de cada sessão é definido pela própria pessoa, sendo recomendado o uso por pelo menos 15 minutos diários. Tal dispositivo depende da habilidade motora e não garante eficácia na entrega homogénea da exposição irradiante efetiva para proporcionar fotobiomodulação diretamente no folículo capilar. Within the scope of employing an object of smaller size, and therefore easily obtainable and used by the user, the state of the art provides, as described in CN1398650, published on 02/26/2003, a hairbrush with red LEDs to promote improved blood circulation, hair growth and less itching. In the same sense, PI 0704946-3 discloses an LED brush for treatment of hair phototherapy. The purpose of this is to use a light-emitting diode brush for hair phototherapy treatment, such as baldness, loss of color and hydration, with a view to improve the well-being of life and health of individuals. The apparatus is composed of a module 10 centimeters wide, 20 centimeters long, and 5 centimeters high. In the extreme module of the application there is a small brush, where are located 10 LEDs in the red colors, with wavelength of 650 nm, and blue, with wavelength of 405 nm. The device also features a power button, and power from internal lithium batteries. The user should turn on the appliance and brush or comb the hair, scouring the entire scalp. The treatment of each session is defined by the person himself, and the use is recommended for at least 15 minutes daily. Such a device depends on the motor ability and does not guarantee effectiveness in the homogeneous delivery of the effective irradiating exposure to provide photobiomodulation directly in the hair follicle.
[013] Uma outra solução similar é descrita no PI 0802844-3, o qual compreende uma chapinha ou uma escova de LED e ultrassom para tratamento de fototerapia e ultrassônica do cabelo, como hidratação, perda de cor e amaciante, com vistas a melhorar o bem-estar de vida e saúde dos indivíduos. O aparelho é composto de um módulo com 20 centímetros de largura, por 10 cm de comprimento, e um cabo de 10 centímetros de comprimento, por 5 centímetros de altura. No módulo de aplicação existe duas pequenas chapas, onde de um lado estão localizados 20 LEDs, nas cores vermelha e azul, de alto brilho com tamanho de onda de 630 nm e 405 nm respectivamente. Na outra extremidade, está posicionada a placa de ultrassom, que estimulam as moléculas de água e estimulam os fios de cabelo.  Another similar solution is described in PI 0802844-3, which comprises a flat and ultrasonic LED or hairbrush or brush for the treatment of phototherapy and ultrasonic hair, such as moisturizing, color loss and softener, with a view to improving the well-being of life and health of individuals. The apparatus is composed of a module 20 centimeters wide, 10 centimeters long, and a cable 10 centimeters long, 5 centimeters high. In the application module there are two small plates, where on one side are located 20 red and blue high brightness LEDs with a wavelength of 630 nm and 405 nm respectively. At the other end, the ultrasound plate is positioned, which stimulate water molecules and stimulate hair strands.
[014] Uma outra solução, a qual elimina a necessidade de uma "manipulação" por parte do usuário, está voltada ao emprego de chapéus e bonés, os quais são colocados na cabeça do usuário e retirados ao final do tratamento. Neste sentido, o documento JP 8092810, publicado em 09/04/1996, descreve um boné destinado a crianças para gerar efeito de contorno através de uma câmera interna de tecido refletora da luz vermelha. Neste não é feita qualquer citação a propriedades capilares.  [014] Another solution, which eliminates the need for "manipulation" by the user, is to use hats and caps, which are placed on the user's head and removed at the end of treatment. In this regard, JP 8092810, published 04/04/1996, describes a cap intended for children to generate contour effect through an inner camera of red light reflecting fabric. In this no citation is made to capillary properties.
[015] Por fim, são também descritas na arte três outras soluções bastante similares e que aludem ao emprego de bonés em tratamentos capilares. Destes está o documento JP 2002 129424, publicado em 09/05/2002, que se refere a um chapéu destinado a promover a revitalização das raízes fracas em virtude do uso constante de chapéus e bonés; o chapéu é de cor vermelha e permite a passagem dos raios IV, além de ser indicado para o tratamento de alopecia areata o que não se tem garantia de casos comprovados quanto a eficácia de cura, pois a alopecia areata é uma doença autoimune. Já o documento JP 2006 037318, publicado em 09/02/2006, se refere a um chapéu que permite apenas a passagem de raios de luz no espectro do vermelho; neste, os raios alcançam o couro cabeludo e ativam as raízes, estimulando o crescimento capilar. Por fim, o documento WO 2008/069154, publicado em 26/06/2008, descreve um chapéu que permite a penetração dos raios de luz vermelhos e próximos ao IV, e que é destinado a promover o crescimento de cabelo e reduzir os males de origem vascular cerebral. [015] Finally, there are also described in the art three other very similar solutions which allude to the use of caps in capillary treatments. Of these, JP 2002 129424, published 09/05/2002, refers to a hat intended to promote the revitalization of weak roots by virtue of the constant use of hats and caps; the hat is red and allows the passage of the IV rays, besides being indicated for the treatment of alopecia areata which is not has guaranteed cases of cure effectiveness, since alopecia areata is an autoimmune disease. JP 2006 037318, published 09/02/2006, refers to a hat that allows only the passage of light rays in the red spectrum; in this, the rays reach the scalp and activate the roots, stimulating the capillary growth. Finally, WO 2008/069154, published 06/26/2008, describes a hat that allows penetration of the red and near-infrared light rays, and which is intended to promote hair growth and reduce the ills of cerebral vascular origin.
[016] A despeito das soluções supra efetivamente serem portáteis e de fácil uso, todas estas apresentam um problema em comum, qual seja, a falta de controle sobre o tempo de exposição do couro cabeludo ao tratamento proposto ou até mesmo de não disponibilizar a entrega de luz do dispositivo até o couro cabeludo. Além de que nos casos que faltam controle de tempo, torna-se bastante complicado realizar o tratamento, já que estes dispositivos devem se deslocar por toda a cabeça do usuário. Assim, uma área pode resultar muito mais irradiada que outra, o que leva a resultados inconsistentes. Ademais, é discutível que um usuário passe 15 minutos seguidos penteando os seus cabelos, dia após dia, por mais leve que seja o dispositivo.  Although the above solutions are effectively portable and easy to use, all of them present a common problem, namely lack of control over the exposure time of the scalp to the proposed treatment or even of not making the delivery available from the device to the scalp. Besides that in cases that lack time control, it becomes quite complicated to perform the treatment, since these devices must move throughout the user's head. Thus, one area may be much more radiated than another, which leads to inconsistent results. In addition, it is debatable that a user spend 15 minutes in a row combing his hair, day after day, however light the device.
OBJETIVOS DA INVENÇÃO OBJECTS OF THE INVENTION
[017] Com o intuito de eliminar as possíveis 'barreiras da luz', como o cabelo, e garantir que toda energia do diodo atinja efetivamente o folículo capilar, é necessário que a luz seja transportada até a superfície de contato do couro cabeludo e, assim, garantir que a exposição radiante proporcione a fotobiomodulação necessária ao estímulo do folículo. O cabelo é composto por melanina, e a melanina é um tipo de cromóforo que absorve a luz nos comprimentos de onda na faixa do espectro eletromagnético na região da luz visível e/ou infravermelho. Sendo assim, é interessante aplicar a luz do diodo diretamente no couro cabeludo para ter ação direta sobre o folículo e evitar absorção pela melanina do cabelo.  In order to eliminate possible 'light barriers' such as hair and ensure that all diode energy effectively reaches the hair follicle, it is necessary that the light is transported to the contact surface of the scalp and, thus ensuring that radiant exposure provides the necessary photobiomodulation to stimulate the follicle. Hair is composed of melanin, and melanin is a type of chromophore that absorbs light at the wavelengths in the electromagnetic spectrum range in the visible and / or infrared light region. Therefore, it is interesting to apply light from the diode directly to the scalp to have direct action on the follicle and prevent absorption by the hair melanin.
[018] Conforme os resumos acima, os processos mencionados não possuem similaridade com o objeto do presente pedido de patente de "CAPACETE DE LED COM TRANSPORTADOR DE LUZ DO DIODO PARA O COURO CABELUDO", motivo pelo qual consideramos que não há impedimentos de ordem técnica nem legal para a obtenção do privilegio solicitado. O objeto da presente patente soluciona problemas de manuseio por parte dos usuários permitindo eficácia na entrega da luz do LED até o couro cabeludo atingindo tanto as 5 regiões mais afetadas pela alopecia e queda capilar quanto no caso de pessoas com bastante cabelo, principalmente, mulheres que estão em fase inicial de alopecia ou queda de cabelo - já que, nestes casos, apenas coloca-se o capacete ajustando-o na cabeça para entregar a luz direto no couro cabeludo da paciente e nada mais. As espículas se ajustam na cabeça por serem retráteis e ainda contribuem por serem capazes de entregar a luz direto no couro cabeludo, pois agem como selecionador dos fios de cabelo, retirando os mesmos e atingindo o folículo capilar com a exposição radiante necessária para a fotobiomodulação e, consequentemente para o tratamento capilar acelerando o crescimento e tornando os cabelos mais fortes e saudáveis. [018] According to the above summaries, the mentioned processes do not have similarity with the object of the present patent application of "LED HELMET WITH CARRIER OF DIODE TO CABELUDE LEATHER", reason why we consider that there are no technical impediments nor legal to obtain the requested privilege. The object of the present patent solves handling problems by users allowing efficiency in the delivery of light from the LED to the scalp reaching both the 5 regions most affected by hair loss and capillary as in the case of people with a lot of hair, mainly women who are in the early stage of alopecia or hair loss - since, in these cases, only the helmet is fitted, adjusting it on the head to deliver the light directly on the hair's scalp patient and nothing more. The spicules fit in the head because they are retractile and still contribute by being able to deliver the light directly to the scalp, as they act as a picker of the hair strands, removing them and reaching the capillary follicle with the radiant exposure necessary for the photobiomodulation and , consequently for the hair treatment accelerating the growth and making the hair stronger and healthier.

DESCRIÇÃO DETALHADA DA INVENÇÃO DETAILED DESCRIPTION OF THE INVENTION
[023] O capacete de LED com transportador de luz é um dispositivo no qual utiliza o princípio da terapia com luz de baixa intensidade (Low Levei Light Therapy - LLL T ou fotobiomodulação). Este dispositivo oferece um tratamento seguro e eficaz. Os efeitos podem ser notados em poucas aplicações, pois atua diretamente no estímulo da microcirculaçao local proporcionando vários benefícios: auxilia em processos inflamatórios, contribui com a redução de edema e redução da dor, acelera o processo de cicatrização de feridas, ajuda na reparação tecidual e acelera o crescimento capilar.  [023] The light-carrying LED helmet is a device in which it uses the principle of Low Levei Light Therapy (LLL T or photobiomodulation). This device offers safe and effective treatment. The effects can be noticed in a few applications, as it acts directly on local microcirculation stimulus providing several benefits: it aids in inflammatory processes, contributes to the reduction of edema and reduction of pain, accelerates the wound healing process, helps in tissue repair and accelerates hair growth.
[024] O objeto da presente invenção soluciona problemas de manuseio por parte dos usuários permitindo eficácia na entrega da luz do LED até o couro cabeludo atingindo tanto as 5 regiões mais afetadas pela alopecia e queda capilar quanto no caso de pessoas com bastante cabelo, principalmente, mulheres que estão em fase inicial de alopecia ou queda de cabelo - já que, nestes casos, apenas coloca-se o capacete de LED ajustando na cabeça para entregar a luz direto no couro cabeludo da paciente e nada mais. As espículas se ajustam na cabeça por serem retráteis, e ainda contribuem por serem capazes de entregar a luz direto no couro cabeludo, pois agem como selecionador dos fios de cabelo, retirando os mesmos e atingindo o folículo capilar com a exposição radiante necessária para o efeito da fotobiomodulação e, consequentemente, para o tratamento capilar.  The object of the present invention solves handling problems by the users allowing effective delivery of light from the LED to the scalp reaching both the 5 regions most affected by alopecia and hair loss as in the case of people with a lot of hair mainly , women who are in the early stage of alopecia or hair loss - since in these cases, just put the LED helmet fitting on the head to deliver light straight into the patient's scalp and nothing else. The spicules fit on the head because they are retractable, and still contribute by being able to deliver the light directly on the scalp, as they act as a picker of the hair strands, removing them and reaching the hair follicle with the radiant exposure required for the effect of photobiomodulation and, consequently, for capillary treatment.
[025] Em geral, os comprimentos de onda na faixa do espectro eletromagnético na região da luz visível e/ou infravermelho apresentam interação a nível celular estimulando ações de analgesias, anti-inflamatórias e cicatrizantes. A luz na região do vermelho e/ou infravermelho do espectro eletromagnético tem ação direta na mitocôndria, mais especificamente agindo no complexo IV da cadeia respiratória (o citocromo c oxidase) liberando NO (óxido nítrico) na corrente sanguínea (considerado ótimo vasodilatador) estimulando produção de Adenosina trifosfato - ATP (energia para a célula) e Espécies Reativas ao Oxigénio - ROS (um dos principais sinalizadores para a transcrição genética e fatores de crescimento da célula). [025] In general, the wavelengths in the range of the electromagnetic spectrum in the region of visible and / or infrared light show interaction at the cellular level stimulating analgesia, anti-inflammatory and cicatrizing actions. Light in the red and / or infrared region of the spectrum (cytochrome c oxidase), releasing NO (nitric oxide) into the bloodstream (considered an excellent vasodilator) stimulating the production of adenosine triphosphate (ATP) (energy for the cell) and Oxygen Reactive Species - ROS (a major marker for gene transcription and cell growth factors).
[026] Este dispositivo apresenta emissores de luz alocados em espículas transmissoras que atingem diretamente o couro cabeludo e são capazes de englobar as cinco regiões mais afetadas pela Alopécia Androgenética por estarem distribuídos homogeneamente na parte interna do capacete de LED, ou seja, consegue atingir a região do vértice, região frontal, região central e as laterais. As fontes de LED apresentam baixa potência e comprimentos de onda na faixa do espectro eletromagnético na região da luz visível e/ou infravermelho.  [026] This device has light emitted from transmitting spicules that directly reach the scalp and are able to encompass the five regions most affected by Androgenetic Alopecia because they are homogeneously distributed in the inner part of the LED helmet, that is, it can reach the apex region, frontal region, central region and lateral regions. LED sources have low power and wavelengths in the range of the electromagnetic spectrum in the region of visible and / or infrared light.
[027] O princípio de funcionamento do capacete de LED com transportador de luz do diodo para o couro cabeludo consiste em poder transportar a luz homogeneamente em toda área a ser tratada com o mínimo possível de perda de luz (seja perdas através de absorção por outras estruturas ou através da perda por fenómenos físicos como reflexão, refração e espalhamento) o que torna uma entrega mais eficiente garantindo o sucesso e confiabilidade do tratamento.  [027] The operating principle of the LED helmet with light diode transporter for the scalp is to be able to carry the light homogeneously in every area to be treated with the least possible loss of light (be it losses through absorption by other structures or through the loss of physical phenomena such as reflection, refraction and scattering), which makes a delivery more efficient, guaranteeing the success and reliability of the treatment.
[028] Pensando em evitar que estruturas externas absorvam parte da energia necessária ao estímulo capilar, como o material da espícula é considerado um ótimo transmissor de luz devido tanto à maior difusão de luz e transparência quanto alta durabilidade e garantia contra amarelado, neste capacete de LED os transmissores de luz do diodo para o couro cabeludo são espículas retráteis para poder encaixar em toda a superfície do couro cabeludo e, assim, proporcionar um tratamento não invasivo e eficiente mesmo no caso de pessoas com bastante cabelo e que estejam tendo problemas capilares. [028] Thinking of avoiding that external structures absorb part of the energy necessary to the capillary stimulus, as the material of the spike is considered a great light transmitter due to the greater diffusion of light and transparency as well as high durability and guarantee against yellow, in this helmet of LED light transmitters from the diode to the scalp are retractable spikes to be able to fit across the surface of the scalp and thus provide a non-invasive and efficient treatment even in the case of people with enough hair and who are having hair problems.
[029] No caso da espícula revestida com material metálico, este último reveste a espícula lateralmente, pois o metal servirá para não deixar que a luz escape lateralmente pela espícula auxiliando e direcionando o transporte da luz do diodo diretamente ao couro cabeludo.  [029] In the case of the metal-coated spike, the latter coats the spike laterally, as the metal will not let the light escape laterally through the spike assisting and directing the transport of light from the diode directly to the scalp.
[030] Para os transmissores de luz que apresentam material resinado, a resina faz o papel de não deixar escapar a luz pelas laterais da espícula aumentando ainda mais a eficiência da entrega de luz diretamente no folículo capilar já que o material da espícula é estruturado de uma maneira que direciona o feixe de luz de maneira angulada. É por isso que, neste caso, não há a necessidade de uma estrutura envolvendo a espícula para barrar a luz lateral, pois o presente transportador de luz apresenta um ângulo de emissão de luz na faixa de 10° a 80°, preferencialmente 25° a 60°, e mais preferencialmente 30°. Além disso, a resina utilizada é uma resina biocompatível para encapsulamento da espícula. [030] For light transmitters with resinous material, the resin plays the role of not letting light escape through the sides of the spike, further increasing the efficiency of light delivery directly into the hair follicle since the spike material is structured a way that angularly directs the beam of light. This is why, in this case, there is no of a structure surrounding the spatter to bar side light, as the present light conveyor has a light emitting angle in the range of 10 ° to 80 °, preferably 25 ° to 60 °, and most preferably 30 °. In addition, the resin used is a biocompatible resin for encapsulating the spike.
[031] Quanto ao material utilizado para a fabricação do capacete terapêutico, estudos foram feitos e dentre os polímeros de engenharia, fibras sintéticas ou plástico injetado como o Acrilonitrila Butadieno Estireno (ABS) oferecem ótimas propriedades físicas, químicas e de fácil processabilidade. São materiais que apresentam excelentes combinações de propriedades, principalmente, no caso de alta resistência ao impacto e ao amarelamento dependendo da formulação. Tratam-se de materiais comercialmente interessantes para vários campos de aplicação como nas indústrias automobilísticas, eletrodomésticos, itens de segurança e estéticos devido a boa interação interfacial permitindo diversos tipos de pintura e metalização.  [031] As for the material used to manufacture the thermal helmet, studies have been made of engineering polymers, synthetic fibers or injected plastic such as Acrylonitrile Butadiene Styrene (ABS) that offer excellent physical, chemical and processability properties. They are materials that have excellent combinations of properties, especially in case of high impact resistance and yellowing depending on the formulation. These are commercially interesting materials for various fields of application such as automotive, home appliances, safety and aesthetic items due to good interfacial interaction allowing various types of painting and metallization.
[032] Desta forma, objeto do presente pedido de patente, o capacete de LED (1) com transportador de luz (6) do diodo para o couro cabeludo, compreende um aro (3) para alocar as espículas metálicas (5) ou resinadas (9) que agem como transmissores de luz do diodo para o couro cabeludo. Mais especificamente, dito aro (3) possui cerca de 190 a 230 furos para alocar as espículas (4).  Accordingly, the subject of the present application, the LED helmet (1) with light conveyor (6) of the diode for the scalp, comprises a ring (3) for allocating the metal (5) or resinous spicules (9) which act as light transmitters from the diode to the scalp. More specifically, said ring (3) has about 190 to 230 holes for allocating the spikes (4).
[033] A espícula (4) é coberta por material metalizado (5) ou resinado (9) que forma o transportador de luz (6) na qual são retráteis devido a espuma flexível (7) e na qual preenche o espaço entre o aro (3) e o casco (8) do capacete de LED e se comporta como amortecedor natural das espículas (4) tornando-as retráteis e capaz de encaixar em diversos formatos de cabeça.  The spike (4) is covered by metallised (5) or resins (9) forming the light conveyor (6) in which they are retractable due to the flexible foam (7) and in which it fills the space between the rim (3) and the helmet (8) of the LED helmet and behaves as a natural shock absorber of the spikes (4) making them retractable and able to fit into various head shapes.
[034] Adicionalmente, o capacete de LED (1) compreende, externamente, um casco (8) que envolve a espuma flexível (7), garantindo ao dispositivo boa resistência ao impacto e proporciona ótimo aspecto visual. Dito casco (8) compreende ainda, na lateral do capacete de LED, o botão que liga/desliga o dispositivo (2). O capacete de LED pode apresentar um cabo ligado a um transformador de tensão 110~220VCA 9~12VCD, ser alimentado via rede elétrica e/ou bateria a ser fixada na parte interior do capacete possivelmente podendo ser entre o casco e o aro. Additionally, the LED helmet 1 externally comprises a hull 8 surrounding the flexible foam 7, ensuring the device good impact resistance and provides great visual appearance. Said hull 8 further comprises, on the side of the LED helmet, the button which switches the device on / off (2). The LED helmet can present a cable connected to a voltage transformer 110 ~ 220VAC 9 ~ 12VDC, be powered via mains and / or battery to be fixed on the inside of the helmet possibly being able to be between the hull and the rim.
[035] A fototerapia tem como princípio, induzir os processos fotobiológicos nas células. A luz monocromática de baixa intensidade, quando apresenta específicos comprimentos de onda, age nos cromóforos gerando respostas celulares específicas e tem sido utilizada para auxiliar no tratamento de diversos problemas de saúde, por exemplo, estimular o crescimento dos cabelos no caso de calvície, perda de cor e hidratação dos fios, melhorar a aparência e aspecto do couro cabeludo como no caso de auxiliar o tratamento de dermatite seborreica (caspa), com vistas a melhorar o bem- estar de vida e saúde dos indivíduos. [035] Phototherapy has the principle of inducing photobiological processes in cells. Low-intensity monochromatic light, when present at specific wavelengths, acts on chromophores to generate specific cellular responses and has been used to aid in the treatment for example, to stimulate hair growth in the case of baldness, loss of color and hydration of the hair, improve the appearance and appearance of the scalp as in the case of assisting the treatment of seborrheic dermatitis (dandruff), with improving the well-being of life and health of individuals.
