Abstract
Mejoras en jeringuillas de un solo uso. Cuenta con un cuerpo tubular (1) que aloja un émbolo (2) una aguja (8), desplazables mediante un vástago (16). Incluye medios para retener la aguja fuera del cuerpo (1), y medios para liberar la aguja ubicándose en el interior del cuerpo (1) tras aplicar la inyección. Incluye medios de obturación estanca (31"'', 32"'' y 33"'') del extremo proximal del cuerpo (1) y medios de posicionado y guiado (52 y 53) de la aguja al actuar el émbolo (2). Incluye medios (28) para introducción estanca del vástago (16) produciéndose el vacío en el cuerpo (1) al desplazar la aguja al exterior, que al ser retenida se aspira automáticamente el líquido. Cuenta con medios (31"'',32"'' y 33"'') de fijación del vástago en cualquier posición para absorber la cantidad requerida de líquido. Los medios de posicionado y de guiado de la aguja (52, 53) constituyen medios que impiden que la aguja salga al exterior tras producirse la absorción del émbolo-aguja al interior del cuerpo. El cuerpo (1) puede incluir la vacuna de origen.
