Abstract
Abstract A safety multiple sample luer adapter assembly is provided having a male connector and a rear blood tube holder each of which is provided with cooperative locking and anti-rotational devices. The locking device of the male connector is a ramp which terminates in a shoulder which in turn terminates in a groove, while the locking device of the rear blood tube holder is a ramp terminating in a seat. The anti-rotational device of the male connector comprises protrusions on the middle portion of the male connector, while the anti-rotational device of the rear blood tube holder comprises notches in a front cylindrical portion of the rear blood tube holder. In assembly, the male connector is aligned with its protrusions engaging the notches of the blood tube holder, and the ramp and shoulder of the male connector are forced past the ramp of the rear blood tube holder until the end of the shoulder of the male connector engages the seat of the rear blood tube holder. In this manner the male connector cannot be removed from and cannot rotate in the rear blood tube holder. After use of the safety multiple sample luer adapter assembly, the assembly can be disposed of without danger of needlesticks, as the rear needle is shielded by the rear blood tube holder.
