Title:	Needle mounting system and a method for mounting a needle assembly
Abstract:	A needle mounting system and methods for mounting a needle assembly on a needle mount are disclosed. The needle mounting system includes a needle hub having protrusions extending radially inward. A needle mount has a plurality of slots to receive the protrusions. The slots have a first portion that defines a passageway substantially parallel to a longitudinal axis of the needle mount and a second portion substantially perpendicular to the axis. The needle hub and mount provide a method wherein a needle assembly may be mounted on an injection device without completely rotating the needle hub relative to the needle mount.

Patent Claims:	1. 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. 2. The needle mount according to claim 1, wherein the angle between the first portion and the second portion is 90 degrees or less. 3. The needle mount according to claim 1, wherein the first portion of the groove is widest at the top end of the needle mount defining an entrance. 4. The needle mount according to claim 1, wherein the protrusions of the needle hub, when present, comprise a circular surface. 5. The needle mount according to claim 1, further comprising structure for determining whether the needle hub is securely mounted on the needle mount. 6. The needle mount according to claim 1, wherein the needle mount is on an adapter top that is secured to an ampoule, or an injection device.
