Abstract

UN PACIENTE INTRODUCE UN DEDO (12) EN UN CAPUCHON QUE CONTIENE UN MANGUITO INFLABLE (13) Y UNA PELICULA PIEZOELECTRICA (11) EN CONTACTO CON EL DEDO PARA PROPORCIONAR SEÑALES DE IMPULSO. EL REBORDE INFLABLE (13) SE INFLA A UNA PRESION CORRESPONDIENTE A UNA PRESION PREDETERMINADA DENTRO DE UNA RELACION SIGNIFICATIVAMENTE SUPERIOR A LA PRESION DIASTOLICA DEL PACIENTE Y A LA MITAD DE LA PRESION DIASTOLICA SUSTANCIALMENTE. LA SEÑAL DE IMPULSO SE ACOPLA A UN ORDENADOR (15). EL ORDENADOR (15) VISUALIZA O IMPRIME LAS SEÑALES REPRESENTATIVAS DE LA AMPLITUD Y VELOCIDAD DE LA SEÑAL DE IMPULSO Y SU DERIVADO E INTEGRAL.
