Abstract

Translated fromPortuguese

"PROCESSO E DISPOSITIVO PARA DETERMINAR A CONCENTRAçãO DE UMA SUBSTâNCIA EM UM LìQUIDO CORPóREO". Para medir a concentração de uma substância no fluido corpóreo, tal como o nível de glicose no sangue ou tecido, um eletrodo de tira (18) e um eletrodo anular (19) são dispostos no espécime. O eletrodo anular (19) está em contato elétrico direto com o espécime, enquanto que o eletrodo de tira (18) está eletricamente isolado do mesmo. O eletrodo de tira (18) é disposto paralelo a um braço ou a uma perna para se obter um comprimento de interação grande. Os eletrodos (18, 19) formam um capacitor em um circuito ressonante. Uma tensão modulada na faixa de MHZ próxima da freq³ência de ressonância ou nessa freq³ência é aplicada aos eletrodos, sendo medida a resposta do fluido corpóreo. Este desenho permite uma medição de alta precisão."PROCESS AND DEVICE FOR DETERMINING CONCENTRATION OF A SUBSTANCE IN A BODY LIQUID". To measure the concentration of a substance in body fluid, such as the level of glucose in the blood or tissue, a strip electrode (18) and an annular electrode (19) are arranged on the specimen. The annular electrode (19) is in direct electrical contact with the specimen, while the strip electrode (18) is electrically isolated from it. The strip electrode 18 is arranged parallel to an arm or leg to obtain a large interaction length. The electrodes (18, 19) form a capacitor in a resonant circuit. A modulated voltage in the MHZ range near or at the resonant frequency is applied to the electrodes and the body fluid response is measured. This design allows for high precision measurement.
