Abstract

CINTA DE ELETRODOS PARA TOMOGRAFIA POR IMPEDáNCIA ELéTRICA. Cinta de eletrodos para tomografia por impedância elétrica, compreendendo uma pluralidade de subconjuntos de eletrodo (20, 20') para injeção e captação de sinais elétricos no paciente, cada subconjunto compreendendo três elementos básicos, formados a partir de uma lâminaeletricamente condutora, a saber, uma zona de contato (22, 52) fixada à pele do paciente e acompanhando sua movimentação, eletricamente ligada por meios condutores flexíveis (24, 53) a uma área terminal (27, 54), sendo esta última afixada a uma ilha de contato (12) provida numa tira de suporte (10) flexível e longitudinalmente indeformável, estando associados, a cada ilha de contato, meios de conexão com os cabos que interfaceiam eletricamente a dita cinta com o aparato de monitoração. Os elementos condutores que formam os ditos subconjuntos utilizam como base comum um material isolante, deformável e poroso, podendo este ser um têxtil não tecido ("non-woven fabric") ou uma espuma de borracha ou material sintético poroso. Devido à deformabilidade do material de base, as zonas de contato acompanham a movimentação da pele do paciente reduzindo o seu desconforto, ao mesmo tempo que as áreas terminais permanecem em posições fixas e conhecidas coincidentes com as ditas ilhas de contato, propiciando a reconstituição precisa da imagem tomográfica. A porosidade do material de base apresenta a vantagem adicional de permitir a respiração da pele do paciente, evitando sua oclusão e o acúmulo de suor.ELECTRICAL IMPEDANCE TOMOGRAPHY BELT. Electrically impeded tomography electrode strap comprising a plurality of electrode subsets (20, 20 ') for injecting and capturing electrical signals in the patient, each subset comprising three basic elements formed from an electrically conductive lamina, namely, a contact zone (22, 52) attached to the patient's skin and accompanying its movement electrically connected by flexible conductive means (24, 53) to a terminal area (27, 54), the latter being affixed to a contact island ( 12) provided with a flexible and longitudinally undeformable support strip (10), with means of connection to each contact island for connecting the cables electrically interfacing said strap with the monitoring apparatus. The conductive elements forming said subassemblies use as a common base a deformable and porous insulating material, which may be a non-woven fabric or a rubber foam or porous synthetic material. Due to the deformability of the base material, the contact zones accompany the movement of the patient's skin reducing its discomfort, while the terminal areas remain in fixed and known positions coincident with said contact islands, providing the accurate reconstitution of the skin. tomographic image. The porosity of the base material has the additional advantage of allowing the patient's skin to breathe, avoiding occlusion and accumulation of sweat.
