Abstract
A low-cost, disposable blood collector which may be collapsed into a low volume disposal package, whereby to maximize both safety and efficiency when discarding the blood collector after use. The blood collector comprises a hollow, collapsible blood collection tube holder for receiving an evacuated blood collection tube, a double-ended hypodermic needle cannula for making a veni puncture and drawing a sample of a patient's blood to a blood collection tube at the interior of the blood collection tube holder, and a collapsible needle cover which surrounds the distal end of the needle cannula. The blood collection tube holder is collapsible from an open, cylindrical configuration, at which to receive a blood collection tube therewithin, to a closed, generally planar configuration, with the blood collection tube removed therefrom. The needle cover is collapsible from an open, expanded configuration, at which the distal end of the needle cannula is exposed for making a veni puncture through the patient's skin, to a closed, generally planar configuration, at which to surround and shield the distal end of the cannula and thereby avoid an accidental needle strike.
