Abstract
A needle shielding device in which, after use, a needle is confined in a chamber having a first hole through which the needle can enter the chamber. The needle is drawn into the chamber through the hole. The chamber is made up of telescopic members. The needle strikes the rear wall of the chamber causing the telescopic members to telescope apart. Once in the chamber, the needle will not readily escape through the first hole.
