ABSTRACT:
Safety multiple sample rear adapter assemblies utilizing one or two molded components are provided. The two component devices have a male connector and a rear blood tube holder each of which is provided with locking devices. In assembly, the male connector is either lockingly forced into the rear blood tube holder, or lockingly screwed into the rear blood tube holder such that the male connector locks permanently into place inside the rear blood tube holder and cannot be removed. After use of the safety multiple sample rear adapter assembly, the assembly can be disposed of without danger of needlesticks, as the rear needle is shielded by the rear blood tube holder. In the single component device, the rear blood tube holder is provided with a male luer on one end, a receiving cylinder on the other end for receiving a standard blood collection vacuum tube, and a dividing wall which acts as the closed end of the receiving cylinder and which supports a nose which extends into the receiving cylinder. The nose holds the rearwardly extending needle as well as providing a device over which a resilient self-sealing needle covering sleeve may be attached. Another aspect of the assembly is a pediatric adapter which is inserted into the rear blood tube holder and accommodates smaller diameter blood collection vacuum tubes.
