DETAILED DESCRIPTION
[0065] Generally, and applicable to all exemplary embodiments of the present invention, the syringe 2 comprises a barrel 2.1 and a neck 2.2 which has a smaller diameter than the barrel 2.1. A needle 3 is mounted to the neck 2.2 and a rigid needle shield (RNS) 4 is removably arranged on the needle 3. When coupled to the needle 3, a portion of the RNS may cover a portion of the neck 2.2, leaving a circumferential gap between the barrel 2.1 and the RNS 4. The RNS 4 has a diameter substantially equal to the diameter of the barrel 2.1.
[0066]
[0067] As shown in
[0068] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by sliding the syringe 2 in the distal direction D into the syringe carrier 2. When the RNS 4 abuts the shoulder sections 1.4, additional axial force may be applied to cause the arms 1.3 to deflect radially. When the RNS 4 has bypassed the shoulder sections 1.4, the sections 1.1.1 may return to the non-deflected position, and the shoulder sections 1.4 may engage the circumferential gap between the barrel 2.1 and the RNS 4 and prevent the syringe 2 from moving in the distal direction D relative to the syringe carrier 1.
[0069] In an exemplary embodiment, the proximal end 1.5 of the body 1.1 may be arranged to receive a finger flange 2.3 of the syringe 2.
[0070] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0071] In an exemplary embodiment, viewing windows 5 may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. In an exemplary embodiment, the windows 5 are formed when cut-outs in the arms 1.3 are substantially contiguous when the arms 1.3 are in the non-deflected position (as shown in
[0072]
[0073] As shown in
[0074] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by sliding the syringe 2 in the distal direction D into the syringe carrier 2. When the RNS 4 abuts proximal ends of the sections 1.1.1, the sections 1.1.1 may deflect radially. When the RNS 4 has bypassed the proximal ends of the section 1.1.1, the sections 1.1.1 may return to the non-deflected position. When the RNS 4 abuts the shoulder sections 1.4, the arms 1.3 may deflect until the RNS 4 bypasses the shoulder sections 1.4. Then, the arms 1.3 may return to the non-deflected position, and the shoulder sections 1.4 and the collar 1.2 may engage the circumferential gap between the barrel 2.1 and the RNS 4 and prevent the syringe 2 from moving in the distal direction D relative to the syringe carrier 1.
[0075] In an exemplary embodiment, the proximal end 1.5 of the body 1.1 may be arranged to receive a finger flange 2.3 of the syringe 2. The proximal end 1.5 may also include a retainer element 1.7 which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.
[0076] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0077] In an exemplary embodiment, viewing windows 5 may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. In an exemplary embodiment, the windows 5 are formed when cut-outs in the sections 1.1.1 are substantially contiguous when the sections 1.1.1 are in the non-deflected position (as shown in
[0078]
[0079] As shown in
[0080] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by opening the sections 1.1.1 about the hinge and placing the syringe 2 in the syringe carrier 2. When the sections 1.1.1 are closed, the pins 1.11 engage the holes 1.10, and the proximal shoulder sections 1.4 form circular shoulders adapted to proximally abut a finger flange 2.3 on the syringe 2 and the distal shoulder section s1.4 to distally engage the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is prevented from moving axially relative to the syringe carrier 1.
[0081] In an exemplary embodiment, the proximal end 1.5 may include a retainer element 1.7 which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.
[0082] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0083] In an exemplary embodiment, viewing windows 5 may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. In an exemplary embodiment, the windows 5 are formed when cut-outs in the sections 1.1.1 are substantially contiguous when the sections 1.1.1 are in the closed position. A projection 1.6 may be formed around each cut-out, and when the sections 1.1.1 are in the non-deflected position, the projections 1.6 may form an outline for the window 5.
[0084]
[0085] As shown in
[0086] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by opening the door 1.12 and sliding the syringe 2 into the syringe carrier 1. When the circumferential gap between the barrel 2.1 and the RNS 4 engages the shoulder section 1.4 on the body 1.1, the door 1.12 may be closed to engage the gap and prevent the syringe 2 from moving axially relative to the syringe carrier 1.
[0087] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0088] In an exemplary embodiment, viewing windows (not shown) may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2. In an exemplary embodiment, the windows are formed as cut-outs.
[0089]
[0090] As shown in
[0091] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by opening the sections 1.1.1 and placing the syringe 2 in the syringe carrier 2. When the sections 1.1.1 are closed, the eyes 1.14 engage the hooks 1.13 and the shoulder sections 1.4 engage the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is prevented from moving axially relative to the syringe carrier 1.
[0092] In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.
[0093] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0094] In an exemplary embodiment, viewing windows may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2.
[0095]
[0096] As shown in
[0097] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by pressing the barrel 2.1 against the clamps 1.15, 1.16, causing the clamps 1.15, 1.16 to deflect and widen the longitudinal slot in the body 1.1. When the barrel 2.1 bypasses the clamps 1.15, 1.16, the clamps 1.15, 1.16 return to their non-deflected position and retain the syringe 2 in the syringe carrier 1. The shoulder sections 1.4 engage the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is prevented from moving axially relative to the syringe carrier 1.
[0098] In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.
[0099] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0100] In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2.
[0101]
[0102] As shown in
[0103] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by sliding the syringe 2 through the collar 1.2 in the distal direction D. When the RNS 4 abuts the shoulder sections 1.4, the body 1.1 may radially deflect (e.g., rotate) about the groove hinges 1.17. When the RNS 4 bypasses the shoulder sections 1.4, the body 1.1 may return to its non-deflected position and retain the syringe 2 in the syringe carrier 1. The shoulder sections 1.4 engage the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is prevented from moving axially relative to the syringe carrier 1.
[0104] In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.
[0105] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0106] In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2.
[0107]
[0108] As shown in
[0109] The syringe 2, with RNS 4 attached to the needle 3 and the circlip 8 attached to the syringe 2, may be loaded into the syringe carrier 1 by sliding the syringe 2 into the syringe carrier 1 in the distal direction D. In a non-deflected position, an outer diameter of the circlip 8 may be substantially equal to a diameter of the body 1.1. Thus, when the syringe 2 with the circlip 8 is inserted into the syringe carrier 1, the circlip 8 may deflect radially until the circlip 8 reaches the annular groove 1.19. The circlip 8 may then expand to the non-deflected position and retain the syringe 2 in an axial position relative to the syringe carrier 1. That is, the circlip 8 may engage the annular groove 1.19 and the circumferential gap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 is prevented from moving axially relative to the syringe carrier 1.
[0110] In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.
[0111] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0112] In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2.
[0113]
[0114] As shown in
[0115] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by sliding the syringe 2 into the syringe carrier 1 in the distal direction D. When the circumferential gap between the barrel 2.1 and the RNS 4 is aligned with the annular groove 1.19, the circlip 8 may be coupled to the body 1.1 and engage the apertures 1.20. By extending inwardly through the apertures, the circlip 8 may be coupled to the outside of the body 1.1 but engage the circumferential gap between the barrel 2.1 and the RNS 4. The engagement between the circlip 8 and the apertures 1.20 prevents the circlip 8 from translating relative to the body 1.1, and the engagement between the circlip 8 and the circumferential gap prevents the syringe 2 from moving axially relative to the syringe carrier 1.
[0116] In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.
[0117] In an exemplary embodiment, the shoulder sections 1.4 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0118] In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2.
[0119]
[0120] As shown in
[0121] The syringe 2, with RNS 4 attached to the needle 3, may be loaded into the syringe carrier 1 by inserting the tool 9 into the enlarged portion 1.21 of the syringe carrier 1. The tool 9 may be a cylinder having an open end adapted to receive the RNS 4. The tool 9 may have a third diameter substantially equal to the second diameter. As the tool 9 is inserted into the enlarged portion 1.21, the tool 9 engages and deflects the resilient barbs 1.22. When the barbs 1.22 are deflected, the RNS 4 can pass the barbs 1.22 in the distal direction D and extend from a distal opening of the body 1.1. When a finger flange 2.3 of the syringe 2 abuts a proximal end of the body 1.1, the tool 9 may be removed and the barbs 1.22 may engage the circumferential gap between the barrel 2.1 and the RNS 4 to prevent the syringe 2 from moving axially relative to the syringe carrier 1.
[0122] In an exemplary embodiment, the proximal end may include a retainer element which is adapted to provide an abutment surface to prevent the syringe 2 from disengaging the syringe carrier 1 in the proximal direction D.
[0123] In an exemplary embodiment, the barbs 1.22 may include proximally-facing contoured surfaces to accommodate a proximal portion of the neck 2.2 of the syringe 2 and distally-facing planar surfaces to abut the RNS 4.
[0124] In an exemplary embodiment, a viewing window may be arranged in the body 1.1 for allowing visual access to the barrel 2.1 of the syringe 2 when the syringe 2 is in the syringe carrier 2.
[0125] It is apparent to those skilled in the art that the number of deflectable arms 1.3, shoulder sections 1.4, clips 8 may be varied without departing from the spirit and scope of the invention. Likewise, all the illustrated embodiments may be implemented with or without viewing windows 5, projections 1.6, restraining features retainer elements 1.7 and clips. Different kinds of clips may likewise be applied.
[0126] Those of skill in the art will understand that modifications (additions and/or removals) of various components of the apparatuses, methods and/or systems and embodiments described herein may be made without departing from the full scope and spirit of the present invention, which encompass such modifications and any and all equivalents thereof.
