Abstract: A device for removing and disposing of blood sampling needles with a minumum of manipulation and without manual contact with any contaminated part. An electrical motor operates a cog wheel to unscrew the needle from the vacuum container sleeve to drop into a closed disposal receptacle. The motor is initiated by depression of a starting switch by the sleeve. The cog wheel is recessed for unimpeded insertion of the needle and sleeve for needle removal. A cycle control circuit assures that the wheel stops in the proper position with the recess adjacent the needle insertion site.
