Abstract
A needle assembly for use with an injection device including a pair of housing members slidably coupled with one another. A needle is structurally attached to one of the housing members such that it is positioned within the two housing members. A first membrane is disposed on an opening of one housing member and a second membrane is disposed on an opening of the other housing member such that the needle is concealed from the view and access of a user thereof. The needle assembly may be contracted by sliding one housing member relative to the other causing the needle to penetrate one of the membranes and administer an injection into or below the skin of the user. Additionally, one or more locking mechanisms may be incorporated to prevent inadvertent needle sticks.
