Abstract

UNA CUBIERTA DE SEGURIDAD QUE RETIENE DE FORMA SEGURA Y FIABLE LA PUNTA DE UNA CANULA EN UNA CAMARA INTERIOR DENTRO DE LA CUBIERTA DE SEGURIDAD. LA CUBIERTA CONSTA DE UN CUERPO ALARGADO CON UNA CAMARA INTERIOR Y UN CANAL AXIAL QUE SE EXTIENDE EN TODA LA LONGITUD DEL CUERPO, A TRAVES DE LA CAMARA INTERIOR, Y DENTRO DEL CUAL SE DESLIZA LA CANULA PARA ALOJARLA. EN LA CAMARA INTERIOR SE COLOCAN ELEMENTOS DE DESPLAZAMIENTO, CADA UNO DE LOS CUALES TIENE UN ORIFICIO POR EL QUE SE PASA LA CANULA Y QUE SE DESPLAZAN CUANDO SE RETRAE LA PUNTA DE LA CANULA, EVITANDO EL AVANCE DE LA PUNTA DE LA CANULA MENCIONADA. EN UNA PRIMERA INCORPORACION, LOS ELEMENTOS DE DESPLAZAMIENTO SON ANILLOS. EN UNA SEGUNDA INCORPORACION, LOS ELEMENTOS SON ESFERAS RIGIDAS CON ORIFICIOS QUE LAS ATRAVIESAN. EN UNA TERCERA INCORPORACION, LOS ELEMENTOS DE DESPLAZAMIENTO SON UN PAR DE ELEMENTOS CONICOS, UNO DE LOS CUALES ESTA DESPLAZADO POR UN MUELLE Y CADA UNO DE LOS CUALES INCLUYE UN ORIFICIO DESFASADO. EN TODAS LAS INCORPORACIONES, ES PREFERIBLE QUE LA CANULA INCLUYA UN REBORDE GRUESO ADYACENTE A LA PUNTA MENCIONADA Y QUE LA CUBIERTA DE SEGURIDAD INCLUYA UNA SECCION ANULAR CORRESPONDIENTE EN SU PARTE POSTERIOR. EL ORIFICIO QUE SE EXTIENDE A TRAVES DE LA PORCION POSTERIOR TIENE UN DIAMETRO MENOR QUE EL REBORDE GRUESO DE LA CANULA, LO QUE IMPIDE QUE LA PUNTA DE LA CANULA SE RETRAIGA DE LA CUBIERTA DE SEGURIDAD.
