Abstract

La presente invención se refiere a una jeringa que comprende un cilindro hueco que tiene un extremo distante esencialmente cerrado y un extremo próximo abierto, y una aguja retráctil que se extiende a través del extremo distante que se comunica con el interior del cilindro, estando la jeringa caracterizado por: un pistón movible axial y reciprocablemente a través del cilindro para acoplar la aguja en el extremo distante del cilindro, y para volver a colocar la aguja desde el extremo distante hasta una posición relativamente próxima dentro del cilindro, el pistón tiene un medio para inclinar o ladear la aguja con relación al eje longitudinal del cilindro, cuando la aguja es acoplada por el pistón y movida hacia la posición relativamente próxima dentro del cilindro.
