7- DESCRIÇÃO DA PATENTE  7- DESCRIPTION OF PATENT
A Patente Modelo de Utilidade para "APERFEIÇOAMENTO EM DISPOSITIVO DE VEDAÇÃO PARA SOQUETE A VÁCUO" (1) constitui-se de um anel regulável para vedação (3) que tem a função de selar os soquetes (4) criando uma maior área de contato entre os mesmos; uma interface protética (2) que é utilizada para proteger a perna do contato direto com o soquete (4); um soquete (4) que é a parte rígida de uma prótese (local onde a perna entra e se encaixa); uma válvula de expulsão de ar (5) que está localizada e conectada no soquete rígido (4) e tem a função de expulsar o ar automaticamente (não deixa o ar entrar, só sair). The Utility Model Patent for "IMPROVEMENT IN VACUUM SOCKET SEALING DEVICE" (1) is an adjustable sealing ring (3) which has the function of sealing the sockets (4) creating a larger contact area between the same; a prosthetic interface (2) that is used to protect the leg from direct contact with the socket (4); a socket (4) which is the rigid part of a prosthesis (where the leg enters and fits); an air exhaust valve (5) which is located and connected to the rigid socket (4) and has the function of automatically expelling the air (it does not let air in, only out).
O anel para vedação (3), do soquete a vácuo (4), é flexível e é colocado diretamente no membro residual ou sobre a interface protética (2), que reveste o membro residual, com a função de selar os soquetes (4) de próteses de membros inferiores (1) criando um ambiente hermeticamente selado, isso possibilita que os membros residuais possam adaptar-se as próteses (1) usando uma vedação regulável e mais proximal possível e como consequência disso criando uma maior área de contato com o soquete (4) oferecendo grande segurança ao amputado; o anel (3) pré-moldado é oferecido em vários diâmetros diferentes para que seja selecionado de acordo com o diâmetro correio do coto de cada paciente; possui formato uniforme, sem emendas ou junções; é feito de material flexível, para permitir a boa adequação aos mais variados formatos de cotos, e claro, ao desenho interno dos soquetes os quais o anel (3) selará.  The sealing ring (3) of the vacuum socket (4) is flexible and is placed directly on the residual limb or on the prosthetic interface (2), which covers the residual limb, with the function of sealing the sockets (4). of lower limb prostheses (1) creating a hermetically sealed environment, this allows the residual limbs to be able to fit the prostheses (1) using as adjustable and proximal a seal as possible and as a consequence creating a larger contact area with the socket (4) offering great safety to the amputees; The preformed ring (3) is offered in several different diameters to be selected according to the mail diameter of each patient's stump; It is uniform in shape, without splicing or joining It is made of flexible material to allow it to fit the most varied stump formats and, of course, the internal design of the sockets to which the ring (3) will seal.
Modo de uso: o paciente coloca o anel de vedação (3) sobre o membro, usando ou não uma interface protética (2), flexível, de característica lisa, sem ranhuras ou desenhos, e para que o novo sistema funcione se faz necessário o soquete rígido (4) transtibial ou transfemural, uma válvula de expulsão de ar (5) conectada na posição distai desse mesmo soquete (4) e o anel de vedação (3) circundando o coto ou a interface protética (2) do paciente; a vedação hermética provocada pelo anel (3) no momento de introdução do coto no soquete rígido (4) faz com que a válvula (5) expulse o ar continuamente até a completa introdução do coto no soquete (4); o anel de vedação (3) criará selo hermético no soquete (4) e com ausência de ar provocado pela ação da válvula (5), esse conjunto de fatores propiciará um ambiente de vácuo no soquete (4), oferecendo maior área de contato e grande segurança para fixação da prótese (1); a adesão do anel de vedação (3) ao coto ou a interface protética (2) é feita apenas por contato, sem qualquer adição de cola ou adesivos, ao estabelecer o diâmetro certo para o paciente, o anel (3) irá adequar-se a circunferência do coto aderindo por contato ao mesmo, permitindo, por exemplo, que seja posicionado em regiões mais proximais ou distais do coto, o que representa uma grande vantagem especialmente para cotos curtos, pois eles não podem ser movidos para cima ou para baixo. Directions for use: The patient places the sealing ring (3) over the limb, whether or not using a smooth, flexible prosthetic interface (2) without grooves or designs, and for the new system to work, it is necessary to rigid socket (4) transtibial or transfemural, an air release valve (5) connected in the distal position of that socket (4) and the sealing ring (3) surrounding the patient's stump or prosthetic interface (2); the hermetic seal caused by the ring (3) at the moment of insertion of the stump into the rigid socket (4) causes the valve (5) to continuously expel air until the complete insertion of the stump into the socket (4); the sealing ring (3) will create airtight seal in the socket (4) and with no air caused by valve action (5), this set of factors will provide a vacuum environment in the socket (4), providing greater contact area and great safety for prosthesis fixation (1); the sealing ring (3) adheres to the stump or the prosthetic interface (2) is made by contact only, without any addition of glue or adhesives, when setting the right diameter for the patient, the ring (3) will fit the circumference of the stump by contacting it, for example allowing it to be positioned in more proximal or distal to the stump, which is a great advantage especially for short stumps as they cannot be moved up or down.
Em resumo, primeiramente define-se o tamanho do anel (3) de acordo com a circunferência do membro com a interface protéticá (2); depois, posiciona-se o anel de vedação (3) o mais proximal possível, aumentando a sucção e a força de alavanca do coto empurrando o membro até o final do soquete (4) e deixando o ar escapar pela válvula de expulsão (5). Para retirar a prótese, basta acionar a válvula de expulsão (5).  In summary, the size of the ring (3) is first defined according to the circumference of the limb with the prosthetic interface (2); the sealing ring (3) is then positioned as close as possible, increasing suction and stump leverage by pushing the member to the end of the socket (4) and letting air escape through the exhaust valve (5) . To remove the prosthesis, simply actuate the expulsion valve (5).
