Method of storing both new and used pen needles
An assembly for storing both new and used pen needles of an injection apparatus, comprising a plurality of storage units each configured to store a pen needle having a needle fixed to a hub, the plurality of storage units being hingedly connected, and each including a storage end, and a dispensing end having an anti-rotation structure, wherein the anti-rotation structure working in conjunction with the hub of the pen needle to prevent rotation of the pen needle when the pen needle is in a dispensing position.
1. An assembly for storing both new and used pen needles of an injection apparatus, comprising:
a plurality of storage units each configured to store a pen needle having a needle fixed to a hub, the plurality of storage units being hingedly connected, and each including:
a storage end; and
a dispensing end having an anti-rotation protrusion; and
a retaining member; and
a closure member comprising an engaging member disposed on each of the plurality of storage units; and
a web that provides a connection between each of the closure members and the corresponding storage unit; wherein
the retaining member of a selected storage unit engages the engaging member of the closure member disposed on an adjacent storage unit;
when the closure member is squeezed by a user, the web acts a pivot for the closure member to rotate with respect to the selected storage unit, the retaining member of the selected storage unit disengages the engaging member of the adjacent storage unit to provide access to the pen needle; and
the anti-rotation protrusion engages the hub of the pen needle to prevent rotation of the pen needle when the pen needle is in a dispensing position.
2. The assembly as recited in claim 1 , wherein the anti-rotation protrusion engages ribs of the hub when the pen needle is in the dispensing position to prevent the pen needle from rotating and permit a user to connect a pen injector to the hub via threading.
3. The assembly as recited in claim 1 , wherein the assembly does not include an inner shield or an outer cover.
4. The assembly as recited in claim 1 , wherein a first storage unit of the plurality of storage units is connected to a lid via a lid hinge.
5. The assembly as recited in claim 1 , wherein a hinge connects a storage unit to an adjacent storage unit of the plurality of storage units.
6. The assembly as recited in claim 1 , wherein a lid hinge and a hinge are disposed on one side of the assembly.
7. The assembly as recited in claim 1 , wherein a lid hinge and a hinge are alternately disposed on opposing sides of the assembly.
8. The assembly as recited in claim 1 , wherein a sterility cover covers an opening of one of the plurality of storage units.
