Abstract

UN DISPOSITIVO PARA MEDIR CONTINUAMENTE EL RITMO DE TRANSPIRACION LOCAL DE LA PIEL INCLUYE UN DETECTOR (1) UTILIZADO PARA APLICAR A LA PIEL HUMANA, EN UN PUNTO DE MEDICION, Y UN ELEMENTO (10) DE SUMINISTRO DE AIRE PARA SUMINISTRAR AIRE DESHUMECTADO AL DETECTOR (1). SE FORMA UNA PRIMERA CAMARA (3) ENTRE EL DETECTOR Y LA PIEL PARA MEZCLAR VAPOR DE AGUA TRASUDADO DE LA PIEL Y EL AIRE DESHUMECTADO SUMINISTRADO DEL ELEMENTO DE SUMINISTRO DE AIRE. SE FORMA UNA SEGUNDA CAMARA (6) DENTRO DEL DETECTOR (1) Y CONECTADA CON LA PRIMERA CAMARA (3) A TRAVES DE UN ORIFICIO (31) DE COMUNICACION. EL DISPOSITIVO INCLUYE ADEMAS UN DETECTOR DE HUMEDAD (4) EN LA SEGUNDA CAMARA. EL DETECTOR DE HUMEDAD (4) VARIA SU CAPACITANCIA CONFORME A LA HUMEDAD RELATIVA DE LA MEZCLA. SE SITUA UN ELEMENTO (5) DETECTOR DE TEMPERATURA EN LA SEGUNDA CAMARA PARA DETECTAR LA TEMPERATURA EN LA SEGUNDA CAMARA Y PARA DAR SALIDA A SEÑALES CORRESPONDIENTES A LA TEMPERATURA. UN ELEMENTO (7) DE SALIDA DEL DETECTOR DE HUMEDAD ESTA MONTADOSOBE EL DETECTOR (1) Y ESTA ELECTRICAMENTE CONECTADO AL DETECTOR DE HUMEDAD (4) PARA DAR SALIDA A UNA SEÑAL DE HUMEDAD. UN PROCESADOR (18) CALCULA EL RITMO DE TRASUDADO, QUE ES INDEPENDIENTE DE LA TEMPERATURA DE LA MEZCLA, BASANDOSE EN LAS SEÑALES DE HUMEDAD Y TEMPERATURA. SE PROPORCIONA UN ELEMENTO PARA GRABAR CONTINUAMENTE LOS DATOS DEL RITMO DE EXUDADO OBTENIDOS PROCEDENTES DEL PROCESADOR.
