1. A mounting system for mounting two different needle arrangements, the mounting system comprising:

  • a generally cylindrical shaped body having a distal end;

    a first coupling mechanism and a second coupling mechanism, wherein the first coupling mechanism and the second coupling mechanism are separate and at the same end segment,the first coupling mechanism comprising a plurality of grooves disposed in a cylindrical outer wall on the generally cylindrically shaped body and defining a passageway that is generally parallel to a cylindrical axis of the generally cylindrical body, and wherein at least one groove of the first coupling mechanism 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 protrusions of a needle hub when present interact with the grooves to form a bayonet coupling, andthe second coupling mechanism comprising male threads disposed on the distal end suitable for threadedly connecting and matingly fitting a threaded needle assembly to the needle mount,thereby allowing either a threaded needle hub to be mounted or dismounted onto the needle mount via the second coupling mechanism, or a bayonet needle hub to be mounted or dismounted onto the needle mount via the first coupling mechanism.
