Patent ID: 8579869

Claim:
A needle mount comprising two separate coupling mechanisms comprising a first coupling mechanism and a second coupling mechanism, the needle mount comprising: a cylindrical outer wall having a top end and threads disposed on the cylindrical outer wall, the first coupling mechanism comprising a plurality of grooves disposed in a cylindrical outer wall beginning at the top end of the cylindrical outer wall and defining a passageway that is generally parallel to a cylindrical axis of the cylindrical outer wall, and wherein at least one groove of the needle mount comprises a first portion and a second portion oriented at an angle to the first portion, wherein the first portion and second portion do not form a part of the second coupling mechanism, and wherein at least one protrusion(s) of a needle hub, when present, interact with at least one groove(s) to form a bayonet coupling, the second coupling mechanism comprising threads disposed on the cylindrical outer wall, suitable for threadedly connecting and matingly fitting a conventional threaded needle assembly to the needle mount, the needle mount thereby allowing either a threaded needle hub to be mounted or dismounted onto the needle mount via a second coupling mechanism, or a bayonet needle hub to be mounted or dismounted onto the needle mount via the first coupling mechanism.
