Abstract

Una jeringa hipodérmica o sacamuestras médica tiene una aguja (115) hueca que es automáticamente retráctil después de usarse. Una pieza moldeada de cuerpo de una sola pieza (101) tiene una cámara principal para un émbolo (105) o envases sacamuestras o cartucho de drogas, una cámara (111) delantera para alojar un resorte (133) a fin de empujar un portaagujas (117), y formaciones de enganches internas (141) para retener el portaagujas (117) con el resorte (133) comprimido en la cámara delantera hasta la retracción automática cuando se liberan las formaciones de enganche (141) mediante el movimiento del extremo de émbolo.
