Abstract

SE EXPONE UNA AGUJA HIPODERMICA (10) PRESENTANDO UNA GEOMETRIA DE PUNTA CON BISELES MULTIPLES (20). EN UNA REALIZACION DE LA INVENCION, LA PUNTA CON BISELES MULTIPLES (20) PRESENTA UN BISEL PRINCIPAL (30), UN PAR DE BISELES EXTREMOS (34A, 34B) Y UN PAR DE BISELES MEDIOS (32A, 32B), CADA UNO INTERMEDIA EL BISEL PRINCIPAL (30) Y UNO DE LOS RESPECTIVOS BISELES EXTREMOS. LOS BISELES PRINCIPAL (30) Y MEDIOS (32A, 32B) ESTAN PROVISTOS DE ANGULOS DE INCLINACION, MEDIDOS ENTRE EL EJE CENTRAL Y UN PLANO DE REFERENCIA, QUE SON SUSTANCIALMENTE IDENTICOS. LOS BISELES EXTREMOS (34A, 34B) ESTAN FORMADOS CON UN ANGULO DE INCLINACION RESPECTO AL EJE CENTRAL, QUE NO ES IGUAL AL ANGULO DE INCLINACION CON EL QUE ESTAN FORMADOS LOS BISELES PRINCIPAL (30) Y MEDIOS (32A, 32B). LA GEOMETRIA DE PUNTA RESULTANTE DE CINCO BISELES, CONTRIBUYE A UNA SUPERFICIE BISELADA MAS CONTINUA, LIBRE DE INTERCEPTACIONES O TRANSICIONES ABRUPTAS ENTRE LAS SUPERFICIES BISELADAS RESPECTIVAS, REDUCIENDO LA FUERZA REQUERIDA PARA EMPUJAR LA PUNTA DE LA AGUJA A TRAVES DE LA PIEL, CARNE, U OTRO MATERIAL.
