Abstract

DISPOSITIVO PARA EL BOMBEO DE PEQUEÑAS CANTIDADES DE LIQUIDO DOTADO DE UN SISTEMA PARA SELECCIONAR EL RITMO DE BOMBEO. LA CAMARA DE BOMBEO ESTA CONSTITUIDA POR UN TUBO ELASTICO DEFORMABLE (19) AL QUE SE HAN ACOPLADO DOS VALVULAS (21,22) QUE IMPIDEN EL RETORNO DE FLUIDO. LAS SUCESIVAS COMPRENSIONES DE UNA UÑETA RIGIDA DESPLAZABLE (29) SOBRE EL TUBO DAN LUGAR A LA ACCION DE BOMBEO. LA UÑETA (29) DE ACCIONAMIENTO ES MOVIDA MEDIANTE UN SOLENOIDE, CUYO RITMO DE EXCITACION PUEDE ELEGIRSE A VOLUNTAD. UNA SEGUNDA UÑETA DESPLAZABLE (31) REGISTRA LAS SUCESIVAS ONDAS DE PRESION, DETECTANDOSE ASI CUALQUIER AVERIA, COMO UNA OBSTRUCCION O LA PRESENCIA DE UNA BURBUJA DE AIRE. EL APARATO POSEE UN CIRCUITO ELECTRICO O ACCIONAMIENTO Y CONTROL. EL DISPOSITIVO PUEDE EMPLEARSE EN LA INYECCION O EXTRACCION DE FLUIDO A ANIMALES POR MEDIO DE AGUJA HIPODERMICA.
