A system for use with evacuated, rubber stoppered sample tubes and double-ended needles facilitates blood collecting operations and prevents accidental punctures from contaminated needles after use. The tube is held in a tubular cartridge with a sliding control for to and fro controlled motion. A holder engages the mid portion of the needle and the cartridge and the sliding control slides the tube onto the needle after blood vessel puncture and slides it off the needle after collection. A finger control releases the needle while avoiding exposure to the point. A refined receptacle in a phebotomy tray holds used needles and dumps them in controlled fashion without overturning the tray. |
