A device for capping and uncapping a hypodermic needle includes a body portion having an opening therein through which the cap of a hypodermic needle may be inserted and removed. The body portion has a base that can be attached to a surface by an adhesive layer or by hook and loop fasteners. The body portion includes a conical helix having screw threads that engage the end of the cap upon rotation of the cap therein. Because the cap is mechanically secured by the helix, the needle can be removed or inserted into the cap while the cap is retained in place. The body portion is made of an inexpensive, resilient foam material.
