摘要

Injection needle (1) for puncture of a layer, especially a portal needle for puncture of the human skin with a needle shaft (2) having a hollow channel in the direction of the longitudinal axis (L), a needle head (4) connected to the needle shaft and a closed needle tip (S) at the end of the needle head. There is an open side needle opening (6) in the needle shaft and/or head perpendicular to the longitudinal axis (L). The distal end of the needle shaft is bent towards (sic) the proximal part of the needle shaft, so that the bent distal end after skin puncture is behind (sic) the skin.
