Abstract

DISPOSITIVO PARA LA DETERMINACION DE NIVELES DE GAS EN LA SANGRE. CONSISTE EN UN SENSOR ELECTROQUIMICO ADAPTADO PARA SU EMPLEO SEPARADO O EN CONTACTO CON EL CUERPO, CARACTERIZADO PORQUE ESTA DOTADO DE UN REVESTIMIENTO (27) EN UNA SUPERFICIE QUE ESTA EN CONTACTO CON EL CUERPO, CON UNA MEMBRANA DE POLIURETANO HIDROFILICO LINEAL QUE TIENE, NORMALMENTE, UN ESPESOR DE 3 A 50 MICRAS, Y CON UN CONTENIDO EN AGUA CUANDO ESTA HIDRATADO DE 10 A UN 40, PREFERIBLEMENTE DE UN 20 A UN 30. LA MEMBRANA SE PUEDE APLICAR FACILMENTE POR REVESTIMIENTO POR INMERSION DE UNA SOLUCION DEL POLIURETANO HIDROFILICO EN UN DISOLVENTE QUE, NORMALMENTE, SERA UNO EN EL QUE NO SEA SOLUBLE EL CATETER (23), QUE PUEDE SER DE CUALQUIER MATERIAL ADECUADO, TAL COMO PVC O NYLON. DE APLICACION EN LA MEDIDA DE LA CONCENTRACION DE OXIGENO, DIOXIDO DE CARBONO O AMBOS, DISUELTOS EN LA SANGRE.
