Abstract
Una aguja hipodérmica que incluye una geometría de punta multibiselada se presenta. En una modalidad, la punta multibiselada incluye un bisel primario, un par de biseles de punta y un par de biseles medios cada uno intermedio con el bisel primario y uno respectivo de los biseles de punta. Los biseles primarios y los medios son proporcionados en ángulos de inclinacion, medios entre el eje central y un plano de referencia que son substancialmente igual. Las puntas biseladas se forman en un ángulo de inclinacion respecto del eje central el cual no es igual al ángulo de inclinacion en el que los biseles primarios y medianos se forman. La geometría de cinco puntos biselados resultante contribuye a una cara de bisel más continua libre de intersecciones o transiciones abruptas entre las caras biseladas respectivas, disminuyendo las fuerzas de penetracion requerida para penetrar la punta de la aguja a través de la piel, carne u otro material.
