Abstract

An injection needle unit for use on a syringe by patient administrated injections, comprising a hub fitting on the syringe which hub carries a needle having a cross section diameter less than 0,320, the needle being made from a super elastic material defined as a material which can obtain recovered elongation of more than 2% without having permanent deformation in the material. The injection needle can be forced away from its original linear shape and the force by which it seeks to return to this linear shape is used for automatic insertion of the needle.
