Abstract

Dispositivo de inyección de un solo uso que comprende: - una jeringa que incluye una aguja de inyección y que delimita una cámara llena de una dosis de líquido para inyectar, obturada por un émbolo solidario de uno de los extremos de un vástago de émbolo dotado de un impulsor en la zona donde está situado su extremo opuesto, - un cuerpo de jeringa solidario de la jeringa, - un estuche de protección, - unos medios de bloqueo relativo en translación practicados sobre el cuerpo de jeringa y el estuche de protección, para permitir un desplazamiento relativo de dicho estuche de protección y del conjunto jeringa/cuerpo de jeringa entre una posición de inyección, en la que la aguja de inyección está desenfundada, y una posición de protección después del uso, en la que dicha aguja de inyección está alojada en el interior del estuche de protección, - unos medios elásticos dispuestos entre el cuerpo de jeringa y el estuche de protección de manera que estén comprimidos en la posición de inyecciónde estos últimos, estando el dispositivo de inyección caracterizado por: - un anillo de cierre dotado de medios de apoyo de los dedos para la inyección del líquido, y de órganos de bloqueo en translación de dicho anillo aptos para mantenerlo en una posición en la que cierra los medios de bloqueo en translación del estuche de protección y del conjunto jeringa/cuerpo de jeringa, en la posición de inyección de estos últimos, en ausencia de esfuerzo ejercido sobre los medios de apoyo de los dedos y para un esfuerzo ejercido sobre estos últimos equivalente a la fuerza de reacción generada que conduce al deslizamiento del émbolo, y para permitir un desplazamiento axial de dicho anillo hacia una posición en la que libera dichos medios de bloqueo y permite el desplazamiento relativo del estuche de protección y del conjunto jeringa/cuerpo de jeringa hacia la posición de protección después del uso de estos últimos, gracias a la acción de los medios elásticos, para un esfuerzo ejercido sobre los medios de apoyo de los dedos superior a la fuerza de reacción generada para el deslizamiento del émbolo, y que se obtiene una vez llegado dicho émbolo al final del recorrido.
