Non grinded needle tip-geometry for an injection needle
The present invention relates to an injection needle (1) for injecting or retracting fluid through the skin of a mammal body and more particularly to non-grinded needle tip-geometry for an injection needle (1) for a reduced penetration force and reduced bleeding. The injection needle (1) comprises o...

| description | The present invention relates to an injection needle (1) for injecting or retracting fluid through the skin of a mammal body and more particularly to non-grinded needle tip-geometry for an injection needle (1) for a reduced penetration force and reduced bleeding. The injection needle (1) comprises of a needle shaft (8) having a centrally located bore disposed along a longitudinal axis (12) connected to a hub (9) by connecting means. The sharpened distal end (11) of the needle shaft (8) has an exit port (13) and two bevels (16,17) surrounding the exit port (13). The bevels (16,17) converge into a tip at the distal end to form a cutting edge (18) and at the proximal end into a heel (19). The bevels (16,17), cutting edge (18) and heel (19) together form the piercing edge that is sharp and continuous without any grinding transitions. |
