hypodermic needle with a protrusion.

摘要

Hypodermic needle (2) to be introduced between the skin (17) and the tissue adjacent to the skin. To separate the skin from the tissue, cartilage or bone (18) below the skin and to prevent the tip (6) of the needle (2) to pierce the tissue below the skin it is proposed to provide the extremity of the needle with a protrusion (4). To prevent damage to the living being in which the needle (2) is introduced the transition of the protrusion (4) to the needle (2) is smooth in all directions. The protrusion (4) is provided on that side of the needle (2) which will be adjacent to the tissue, cartilage or bone (18) of the living being. <IMAGE>
