Point protection and method for use at hypodermic puncture needles characterised by that the point protector's active protection function is effected by a thin walled tube that externally or internally is closely fitted to the puncture needle (1) so that a supporting, evenly distributed normal pressure on the thin walled tube arises which substantially increases its capacity to sustain the forces that after accomplished tissue penetration may be expected to affect the protector, without embarrassing deformation, and by that prevent accidental scratch, chafe and/or stab injuries caused by the sharp needle point inclusive tissue damages at punctured tissue for instance at the inside punctured blood vessels, the so-called endothelium.
