Abstract: A new disposable needlecap holder for safe, one-handed recapping of hypodermic syringe needles is disclosed. The needlecap holder is a generally rectangular solid having a back face with an adhesive surface so that the solid can be attached to a horizontal or vertical surface, such as a table, cart or wall. A front face on the solid has an opening for a bore that extends through the solid toward the back face. The bore is sized to hold a needlecap. A bullseye ring surrounds the bore opening. The back face is at an acute angle to the front face. To use, the back face is attached to a flat surface and a needlecap inserted into the bore. Using the bullseye ring as a guide, a healthcare worker inserts a needle into the held needlecap until it snaps into place. The needlecap holder can be made of any lightweight disposable plastic material.
