"CÁPSULA PARA TESTE DE ACUIDADE VISUAL E MÉTODO VIRTUAL DE AFERIÇÃO, ARMAZENAMENTO DE DADOS E DIAGNOSE". "CAPSULATE FOR VISUAL ACUITY TEST AND VIRTUAL METHOD OF MEASUREMENT, DATA STORAGE AND DIAGNOSIS".
CAMPO TÉCNICO DA INVENÇÃO TECHNICAL FIELD OF THE INVENTION
[001] A presente patente de invenção trata de uma cápsula para teste de acuidade visual e método virtual de aferição, armazenamento de dados e diagnose onde, notadamente, dita cápsula é idealizada para ser instalada em consultórios, clínicas e correlates e apresenta características inovadoras que favorecem a associação com o método virtual para a prática do teste de acuidade visual de forma segura, ágil e com análise dos dados colhidos de forma remota, garantindo um resultado eficaz e que pode ser acessado em qualquer momento por meio de aparelhos móveis ou similares viabilizando, assim, o acompanhamento do histórico do paciente por diversos especialistas. [001] The present invention patent deals with a capsule for visual acuity testing and a virtual method of measurement, data storage and diagnosis where, notably, said capsule is designed to be installed in offices, clinics and the like and presents innovative features that favor the association with the virtual method for the practice of the visual acuity test in a safe, agile way and with analysis of the data collected remotely, guaranteeing an effective result that can be accessed at any time through mobile devices or similar enabling , thus, the follow-up of the patient's history by several specialists.
HISTÓRICO DA INVENÇÃO BACKGROUND OF THE INVENTION
[002] De uma forma geral, os testes de aferição de acuidade visual são idealizados para quantificar a acuidade de seres humanos de forma a detectar problemas de visão em pacientes de qualquer idade, bem como, pacientes que não se comunicam verbalmente ou cuja comunicação é realizada por linguagem de sinais, como por exemplo, os infantes em fase pré-verbal dos zero aos quatro anos de vida. [002] In general, visual acuity measurement tests are designed to quantify the acuity of human beings in order to detect vision problems in patients of any age, as well as patients who do not communicate verbally or whose communication is carried out by sign language, such as, for example, infants in the pre-verbal phase from zero to four years of age.
[003] Da mesma forma, dito teste de aferição de acuidade visual pode ser praticado em pacientes que sofreram lesões encefálicas tetraplegiantes e sem fala, contudo, apresentam a preservação da movimentação ocular ou, mesmo, em pacientes sem adequada fidedignidade de informação verbal como casos de demência e que podem ter, também, suas acuidades visuais comprovadas por este teste. [003] Likewise, said visual acuity measurement test can be performed in patients who have suffered quadriplegic brain injuries and without speech, however, have preserved eye movement or even in patients without adequate reliability of verbal information such as cases of dementia and who may also have their visual acuity confirmed by this test.
[004] A aferição da acuidade visual ocorre pelo princípio preferencial que seres humanos naturalmente preferem olhar para algo que exiba algum detalhe, ao invés de, focar para algo sem detalhe algum, ou seja, um ser humano diante de uma parede branca automaticamente focará seu olhar em qualquer detalhe desta parede que destoe de seu fundo branco, como por exemplo um ponto de coloração distinta. [004] The measurement of visual acuity occurs by the preferential principle that human beings naturally prefer to look at something that displays some detail, rather than focusing on something without any detail, that is, a human being in front of a white wall will automatically focus his look at any detail of this wall that differs from its white background, such as a distinct color spot.
[005] Dessarte, o teste de acuidade visual, também, conhecido como teste de 'Teller' é constituído por cartões retangulares provido de orifício central e onde um lado é ausente de ilustrações, enquanto o outro lado da mesma superfície, porém, em direção oposta é previsto um conjunto de listras verticais ou horizontais espaçados entre si. [005] Thus, the visual acuity test, also known as the 'Teller' test, consists of rectangular cards with a central hole and where one side is absent from illustrations, while on the other side of the same surface, however, in the opposite direction, a set of vertical or horizontal stripes spaced apart is provided.
[006] Para a prática do supracitado teste, o médico examinador se posiciona em frente ao paciente segurando o cartão a uma distância que segundo as regras deste teste pode variar de 84, 55 ou 38 cm dos olhos do paciente. A face do cartão ausente de ilustrações fica voltada para o médico e, a face provida de ilustrações, fica voltada para o paciente. Como o detalhe está localizado apenas em uma das metades da face do cartão voltada para o paciente, caso ele perceba a existência deste detalhe o médico atestará este fato observando através do orifício do cartão, se o paciente olhou para o detalhe ou não. [006] For the practice of the aforementioned test, the examining physician positions himself in front of the patient holding the card at a distance that according to the rules of this test can vary from 84, 55 or 38 cm from the patient's eyes. The side of the card without illustrations is facing the doctor and the side with illustrations is facing the patient. As the detail is located only on one of the halves of the face of the card facing the patient, if he notices the existence of this detail, the doctor will attest to this fact by looking through the hole in the card, whether the patient looked at the detail or not.
[007] Assim, caso o paciente tenha enxergado o detalhe do primeiro cartão, passa-se para o segundo cartão e, assim, sucessivamente conforme a observação para o lado que contém detalhes. No momento em que o paciente não mais olhar para o detalhe, anota- se que sua acuidade visual é correspondente ao último cartão no qual ele foi capaz de perceber o detalhamento. [007] Thus, if the patient has seen the detail on the first card, they move on to the second card and, so on, successively according to the observation for the side that contains details. When the patient no longer looks at the detail, it is noted that his visual acuity corresponds to the last card in which he was able to perceive the detail.
[008] Apesar do teste ter eficácia comprovada muitos fatores podem influenciar no diagnóstico como, por exemplo, influências visuais que permitem o desvio da atenção do paciente, instabilidade com a manipulação dos cartões, iluminação inapropriada e outros fatores que interferem na prática do teste. [008] Although the test has proven effectiveness, many factors can influence the diagnosis, such as visual influences that allow the patient to divert attention, instability when handling the cards, inappropriate lighting and other factors that interfere with the practice of the test.
[009] O requerente, atuante na área e preocupado em oferecer melhores condições para a execução dos testes visuais, é depositante do documento de n^. BRIO.2019.012081-9 que trata de cabine para teste de quantificação da acuidade visual compreendida por estrutura modular compondo um ambiente isolado para o paciente realizar o teste de acuidade, aplicado por meio da leitura de cartões de 'Teller' acomodados em área de visualização prevista na porção central da parede móvel deslizante através de rodízios em trilhos instalados no pavimento e teto sustentado por perfis. [009] The applicant, active in the area and concerned with offering better conditions for the execution of visual tests, is the depositor of document n^. BRIO.2019.012081-9 dealing with a cabin for the quantification of visual acuity test comprised of a modular structure comprising an isolated environment for the patient to perform the acuity test, applied by reading 'Teller' cards accommodated in the preview area in the central portion of the movable wall sliding through casters on rails installed on the floor and roof supported by profiles.
[010] Outro documento depositado pelo memo requerente de n^. PCT/BR2020/050100 apresenta aperfeiçoamentos na cabine modular formada por estrutura confeccionada em madeira, 'drywall', PVC ou outro tipo de material, a qual é provida de área de visualização de cartões prevista na porção central da parede móvel deslizante, sendo que defronte a parede móvel e coplanar a parede posterior da cabine modular é instalado um assento para acomodação do paciente e possível acompanhante; dita cabine modular compõe um ambiente controlável e inclui regulagens que configuram um ambiente controlado para a aplicabilidade dos testes como teste de acuidade visual preferencial de 'Teller', teste cromático e contraste, bem como, o teste para a avaliação de fotossensibilidade e avaliação de possíveis alterações oculares. [010] Another document deposited by the same applicant of n^. PCT/BR2020/050100 presents improvements in the modular cabin formed by a structure made of wood, 'drywall', PVC or another type of material, which is provided with an area for viewing cards provided for in the central portion of the movable wall sliding, with a seat in front of the movable wall and coplanar with the posterior wall of the modular cabin to accommodate the patient and a possible companion; said modular cabin composes a controllable environment and includes adjustments that configure a controlled environment for the applicability of tests such as the 'Teller' preferential visual acuity test, chromatic and contrast test, as well as the test for the evaluation of photosensitivity and evaluation of possible eye changes.
ANÁLISE DO ESTADO DA TÉCNICA ANALYSIS OF THE STATE OF THE TECHNIQUE
[011] Em pesquisa realizada em bancos de dados especializados foram encontrados documentos referentes à cabine/cápsula para teste de acuidade visual e método, tal como, apresentado no documento de n^. US5910834 que trata de método e aparelho para usar a realidade virtual para apresentar um estímulo de teste de uma primeira cor sobreposta em um fundo de uma segunda cor, para testar e quantificar informações visuais do olho, das vias visuais e do cérebro. A configuração do arnês permite que o paciente observe um campo de visão no qual os estímulos de teste sequenciados são apresentados por um dispositivo de excitação comandado por um computador. Feedback sensorial interativo para o paciente permite a apresentação orientada por computador e modulação do teste para medir estímulos com precisão como visuais desempenho em campo, acuidade e de cores. O uso do sistema permite ao paciente uma liberdade de movimento sem precedentes da cabeça e do corpo, minimizando ou mesmo eliminando o estresse e a fadiga comuns aos sistemas convencionais de teste de campo visual de realidade não virtual. [011] In research carried out in specialized databases, documents were found referring to the cabin/capsule for visual acuity test and method, such as presented in document n^. US5910834 which deals with method and apparatus for using virtual reality to present a test stimulus of a first color superimposed on a background of a second color, to test and quantify visual information from the eye, visual pathways and brain. The headgear configuration allows the patient to observe a field of view in which sequenced test stimuli are presented by a computer driven excitation device. Interactive sensory feedback to the patient enables computer-guided presentation and test modulation to accurately measure stimuli such as visual field performance, acuity, and color. Use of the system allows the patient unprecedented freedom of movement of the head and body, minimizing or even eliminating the stress and fatigue common to conventional non-virtual reality visual field testing systems.
[012] O documento de n^. US2019125179 revela um sistema para replicar um teste de acuidade visual padronizado, compreendendo um visualizador binocular conectado a um smartphone. Um visualizador binocular compreende um alojamento formado por um par de tubos tendo espaços vazios permitindo a visualização através de um par de tubos de lente com comunicação visual com uma segunda lente, uma primeira lente, uma abertura e uma tampa frontal. Os sistemas ópticos usam uma combinação engenhosa de superfícies de lente frontal e traseira, demagnificação e outros sistemas para replicar fielmente as linhas de visão percebidas por um usuário de um teste tradicional. O sistema também permite a incorporação de outros testes conduzidos com ambos os olhos, incluindo sensibilidade de cor e contraste, além disso, ao colocar uma lente sintonizável deformável entre a segunda lente e o olho, o dispositivo serve como um refratômetro oftálmico, permitindo uma estimativa de refração equivalente esférica para cada olho. [012] Document No. US2019125179 discloses a system for replicating a standardized visual acuity test, comprising a binocular viewer connected to a smartphone. A binocular viewer comprises a housing formed by a pair of tubes having voids allowing viewing through a pair of lens tubes visually communicating with a second lens, a first lens, an aperture and a front cover. The optical systems use an ingenious combination of front and rear lens surfaces, demagnification and other systems to faithfully replicate the lines of sight perceived by a test user traditional. The system also allows the incorporation of other tests conducted with both eyes, including color and contrast sensitivity, in addition, by placing a deformable tunable lens between the second lens and the eye, the device serves as an ophthalmic refractometer, allowing an estimate of spherical equivalent refraction for each eye.
[013] O documento de n^. CN205903239 revela um teste de acuidade visual e instrutor baseado em realidade virtual, incluindo: aparelho montado na cabeça, com dispositivo de processamento de imagem de conexão de aparelho montado em cabeça, com equipamento de controle inteligente de conexão de aparelho montado em cabeça e instalação de processamento de imagem e com equipamento de controle inteligente de comunicação de conexão de equipamento anti-ofuscamento e tontura.

[014] Os documentos supracitados, apesar de pertencerem ao mesmo campo de aplicação diferenciam-se do presente invento em questão, como se verá adiante, garantindo, assim, que o mesmo atenda, plenamente, aos requisitos legais de patenteabilidade. [014] The aforementioned documents, despite belonging to the same field of application, differ from the present invention in question, as will be seen below, thus ensuring that it fully meets the legal requirements of patentability.
OBJETIVOS DA INVENÇÃO OBJECTIVES OF THE INVENTION
[015] Nesse sentido é objetivo da presente invenção apresentar uma cápsula para teste de acuidade visual e método virtual de aferição, armazenamento de dados e diagnose cuja associação entre ambos permite a prática do teste de acuidade visual de forma segura e ágil, e como o teste é realizado a partir de parâmetros pré-programados e a análise dos dados colhidos é realizada de forma remota, garante-se um resultado eficaz passível de ser acessado pelo(s) profissiona l(is) a qualquer momento, por meio de aparelhos móveis ou similares, viabilizando, assim, o acompanhamento do histórico do paciente por diversos especialistas. [015] In this sense, the objective of the present invention is to present a capsule for visual acuity testing and a virtual method of measurement, data storage and diagnosis whose association between both allows the practice of visual acuity testing in a safe and agile way, and how the The test is carried out based on pre-programmed parameters and the analysis of the collected data is carried out remotely, guaranteeing an effective result that can be accessed by the professional(s) at any time, through mobile devices or similar, thus enabling the follow-up of the patient's history by several specialists.
[016] Este objetivo é possível de ser alcançado devido a um método operacional aplicado na cápsula compreender um programa de computador embarcado que viabiliza o processamento de dados e a troca dos optotipos de forma virtual e remota, visando a aplicação dos testes, optotipos que são apresentados num monitor, precisamente uma 'Smart TV' instalada na porção interna da cápsula e acionada remotamente mediante um aplicativo móvel, mais conhecido por "APP", desenvolvido para estas finalidades e instalado em aparelho móvel do tipo ‘smartphone’ ou equivalente. [016] This objective is possible to be achieved due to an operational method applied in the capsule comprising an embedded computer program that enables data processing and the exchange of optotypes virtually and remotely, aiming at the application of tests, optotypes that are displayed on a monitor, precisely a 'Smart TV' installed inside the capsule and activated remotely through a mobile application, better known as "APP", developed for these purposes and installed on a mobile device of the 'smartphone' type or equivalent.
[017] Outro objetivo desta invenção reside no fato da apresentação dos optotipos na 'Smart TV', para a prática do teste, viabilizar a estabilidade durante a leitura do cartão pelo paciente permitindo, assim, a ausência de qualquer tipo de influência ou distração na prática do teste e, consequentemente, a obtenção de um resultado mais eficaz. [017] Another objective of this invention lies in the fact that the presentation of the optotypes on the 'Smart TV', for the practice of the test, enables stability during the reading of the card by the patient, thus allowing the absence of any kind of influence or distraction in the practice of the test and, consequently, obtaining a more effective result.
