Abstract

Un jeringa auto-retráctil que comprende un barril de jeringa (12) que tiene un émbolo hueco (13) ubicado deslizablemente en el mismo. La instalación de una aguja comprende una aguja y un núcleo de aguja (17), con una ranura en el extremo del barril (12) para sostener el núcleo de la aguja (17) y un resorte dispuesto sobre dicho núcleo de aguja (17) y que actúa entre el núcleo de la aguja (17) y el extremo del barril (12). El núcleo de aguja (17) tiene una ranura alrededor de su circunferencia en la cual se acopla un medio de bloqueo a fin de retener el núcleo de la aguja (17) en el extremo del barril de jeringa (12) durante su uso. El émbolo (13) al término de una inyección y cuando se oprime adicionalmente la autoretracción del núcleo de aguja (17) mediante el desalojo de dicho medio de bloqueo de dicha ranura para liberar el núcleo de aguja y el resorte se retraigan dentro del émbolo hueco (13) bajo la influencia del resorte.A self-retracting syringe comprising a syringe barrel (12) having a hollow plunger (13) slidably located therein. The installation of a needle comprises a needle and a needle core (17), with a groove at the end of the barrel (12) to hold the needle core (17) and a spring disposed on said needle core (17) and acting between the needle core (17) and the barrel end (12). The needle core (17) has a groove around its circumference in which a locking means is engaged in order to retain the needle core (17) at the end of the syringe barrel (12) during use. The piston (13) at the end of an injection and when the self-retraction of the needle core (17) is additionally depressed by evicting said locking means from said groove to release the needle core and the spring retract into the hollow plunger (13) under the influence of the spring.
