SYSTEMS AND METHODS FOR PRE-FILLED MEDICAL DELIVERY ASSEMBLIES
A pre-filled medical delivery assembly comprising a blow-fill-seal (BFS) bottle with a collapsible reservoir, a neck portion, and a side flange, an administration assembly comprising a collar with a mounting socket with an interior seat into which the neck portion is axially inserted, a needle hub coupled to a double-ended needle comprising a piercing end within the mounting socket and an administration end. A needle shield covers the needle after use and includes a shield base, a shield element, and a hinge flexibly connecting the shield base and the shield. The shield base further comprises at least one circumferential notch that couples to at least one side flange of the BFS bottle.
1 . A pre-filled medical delivery assembly, comprising:
a blow-fill-seal (BFS) vial defining a collapsible reservoir, a neck portion, and at least one vial flange formed adjacent to the neck portion;
a mounting collar comprising (i) a first end comprising a mounting socket comprising an interior seat into which the neck portion of the BFS vial is inserted, (ii) a second end comprising a collar mating feature, and (iii) at least one axial slot extending axially from the first end and toward the second end;
a needle hub comprising at least one hub mating feature cooperatively mated with the collar mating feature;
a double-ended needle disposed through and coupled to the needle hub and comprising a piercing end housed within the needle hub and an administration end distal from the needle hub;
a cap removably attached to the needle hub and covering the administration end of the needle; and
a needle shield comprising a shield base coupled to the mounting collar, a shield element, and a hinge element flexibly connecting the shield base and the shield element, wherein the shield element comprises a retention element having a retention barb configured to capture the administration end of the double-ended needle within a retention space of the retention element, and wherein the shield base comprises at least one internal radial protrusion that engages with the at least one axial slot.
2 . The pre-filled medical delivery assembly of claim 1 , wherein the shield base comprises an annular element through which the mounting collar is inserted.
3 . The pre-filled medical delivery assembly of claim 1 , wherein the shield base further comprises at least one circumferential notch that couples to the at least one vial flange.
4 . The pre-filled medical delivery assembly of claim 1 , wherein the at least one vial flange is disposed within the at least one axial slot.
5 . The pre-filled medical delivery assembly of claim 1 , wherein the shield element of the needle shield further comprises a locating element disposed further from the administration end of the double-ended needle than the retention barb, the locating element having a pair of locating barbs configured to capture an intermediate portion of the double-ended needle.
6 . The pre-filled medical delivery assembly of claim 1 , wherein the shield base is retained between the at least one vial flange and the needle hub.
7 . The pre-filled medical delivery assembly of claim 1 , wherein the collar is integral with the needle hub.
8 . A medical administration assembly, comprising:
a collar having a first end defining a mounting socket comprising an interior seat operable to accept an exterior flange of a blow-fill-seal (BFS) vial that is axially mated, and a second end defining a hub socket comprising a collar mating feature;
a needle hub comprising at least one hub mating feature cooperatively mated with the collar mating feature, the needle hub being coupled to a double-ended needle disposed through the needle hub;
a needle shield comprising a shield base coupled to the collar, a shield element, and a hinge element flexibly connecting the shield base and the shield element, wherein the shield element comprises a retention element having retention barb configured to capture the administration end of the double-ended needle within a retention space of the retention element, and wherein the shield base further comprises at least one circumferential notch that couples to at least one vial flange of the BFS vial.
9 . The medical administration assembly of claim 8 , wherein the shield element is rotated about the hinge element and coupled with the administration end of the needle after the cap is removed.
10 . The medical administration assembly of claim 8 , further comprising a removable needle hub seal covering an opening of the mounting socket.
11 . The medical administration assembly of claim 8 , wherein the collar is integral with the needle hub.
