Zusammenfassung:A one piece molded vacuum tube holder is fitted with a one piece molded needle hub assembly. A needle protection device is further rotatably mounted to the neck of the one piece vacuum tube holder. One portion of a locking mechanism is provided at the neck of the one piece vacuum tube holder and a second portion of the locking mechanism is provided at the needle hub of the needle hub assembly, so that when the needle hub assembly is press fit to the vacuum tube holder, the two portions of the locking mechanism will coact to fixedly retain the needle hub assembly within the vacuum tube holder. The one piece vacuum tube holder is configured to have an elongate needle cover integrally extending from its neck. A tamper evident notched joint is provided at the junction where the needle cover is connected to the neck. When used, a user applies a predetermined torque to the needle cover, relative to the rest of the vacuum tube holder, to separate the needle cover from the neck of the holder to thereby expose the one end of the double-ended needlle extending from the needle hub. After use, the contaminated needle is covered by the needle safety housing, with integral hooks in the housing fixedly grasping the contaminated needle to prevent it from being further exposed. The opening of the vacuum tube holder through which a conventional vacuum tube is inserted may be sealed for sterilization and transport of the device. A finger grasp mechanism, which may be in the shape of a wing nut, may be coupled to the needle cover to enhance the separation of the needle cover from the neck of the holder. L'invention concerne un support de tube à vide moulé monobloc adapté à un ensemble pavillon d'aiguille moulé monobloc, un dispositif de protection d'aiguille étant monté rotatif sur le col du support de tube à vide monobloc. Un mécanisme de blocage a une partie sur le col du support de tube à vide monobloc et une deuxième partie sur le pavillon de l'ensemble pavillon d'aiguille, de sorte que quand ce dernier est ajusté serré sur le support de tube à vide, les deux parties du mécanisme de blocage coopère pour maintenir l'ensemble pavillon d'aiguille à l'intérieur du support de tube à vide. Ce support de tube à vide monobloc est conçu pour avoir un protecteur d'aiguille allongé s'étendant dans le prolongement du col. Un assemblage à cran inviolable se trouve à la jonction entre le protecteur d'aiguille et le col. A l'usage, l'utilisateur applique un couple déterminé sur le prote
