Abstract
The several embodiments include a hypodermic needle with a hollow member positioned over a portion of the needle, thus covering that portion of the needle. Prior to and during use, the hollow member is held away from the piercing end of the needle to allow it to be used in the normal manner. After the needle has become contaminated, a simple action by the user places the hollow member in a position covering the piercing end of the needle, and the hollow member is supported in this position against rearward pressure. The hollow member is similarly kept from sliding off the end of the needle.
