NON GRINDED NEEDLE TIP-GEOMETRY FOR AN INJECTION NEEDLE |
摘要 |
<p>The present invention relates to an injection needle for injecting or retracting fluid through the skin of a mammal body and more particularly to non-grinded needle tip-geometry for an in- jection needle for a reduced penetration force and reduced bleeding. The injection needle comprises of a needle shaft having a centrally located bore disposed along a longitudinal axis connected to a hub by connecting means. The sharpened distal end of the needle shaft has an exit port and two bevels surrounding the exit port. The bevels converge into a tip at the distal end to form a cutting edge and at the proximal end into a heel. The bevels, cutting edge and heel together form the piercing edge that is sharp and continuous without any grinding transitions.</p> |
