ABSTRACT:
A needle holder for use with a double ended blood collection needle having a first sharpened end and a second sharpened end and a hub intermediate the first and second ends of the needle, and an evacuated blood collection tube stoppered at one end by a rubber-like stopper. The needle holder includes a rotatable sleeve mounted on the needle hub holding end of the needle holder. The sleeve has an end wall adjacent the end wall of the needle holder, the end wall of the sleeve defining an oval aperture therethrough. The end wall of the needle holder defines a recess for receiving the needle hub so as to prevent rotation of the needle hub with respect to the needle holder. As the sleeve is rotated with respect to the needle holder, portions of the end wall of the sleeve adjacent the oval aperture are caused to overlie portions of the needle hub, thereby preventing axial displacement of the needle with respect to the needle holder. This action is reversible by further rotation of the sleeve, or preferably, by reverse rotation of the sleeve back to its original orientation, thereby releasing the needle hub. One benefit is that a used needle can be disengaged from the needle holder without one's hand approaching the used end of the needle, thereby reducing the risk of sticking oneself with a contaminated needle.
