Abstract

La presente invención se refiere un conjunto de jeringa hipodérmica que comprende: un barril alargado que tiene un extremo próximo abierto, una cámara para retener fluido y una porción de punta que se extiende desde un extremo distante del barril, que tiene un pasaje a través de la misma que se comunica con la cámara; una cánula de aguja que tiene un extremo distante que se extiende hacia afuera desde la porción de punta, que incluye un paso a través de la misma en comunicación de fluído con el pasaje; un conjunto de cubierta que incluye un forro de aguja elástico que tiene un extremo próximo abierto, un extremo distante cerrado, una pared lateral que define un receptáculo dentro de la misma, estando el forro de aguja elástico colocado dentro de una cubierta de aguja rígida alargada, que tiene un extremo próximo abierto, un extremo distante cerrado y una pared lateral entre los mismos; un medio para mantener el forro dentro de la cubierta de manera que el forro no pueda retirarse de la cubierta durante el uso normal del conjunto de jeringa, incluyendo el forro un medio sellador de cánula en el extremo distante del receptáculo, para proporcionar un sello hermético al fluido entre el paso y el ambiente del conjunto de jeringa; estando el conjunto de cubierta o protección de aguja colocado con el extremo de la cánula acoplando el medio sellante de cánula y el extremo próximo del forro acoplando en forma retirable la porción de punta, para mantener el conjunto de cubierta en el barril mientras que se sella simultáneamente el paso de la cánula, a fin de que en el forro rodee la porción completa de la cánula que se extiende hacia afuera desde la porción de punta; estando la cubierta y el forro estructurados de manera que la cubierta no pueda amasarse manualmente o separarse manualmente del forro, mientras que el forro se coloca apropiadamente sellando la cánula y acoplando la porción de punta del barril; y siendo el conjunto de cubierta de aguja fácilmente acoplable y retirable en y desde el barril y utilizando la cánula fuerza manual aplicada a la cubierta.
