Abstract
A conical depression for guiding a hypodermic needle into a desired location and having a hole at the center for limiting the maximum needle diameter that can be used to access that location. The diameter of the hole prevents access by needles having a diameter greater than the diameter of the hole. The conical depression has a smooth surface and an angle such that needles that are inserted into the conical depression misaligned with the hole will be guided to the hole without damaging the tip of the hypodermic needle.
