Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a sterilization support device for a pre-filled syringe with a booster. Background Technology
[0002] After the pre-filled syringe (PFS) is filled with the medication, an injector and plunger need to be installed before the label is affixed. Traditional sterilization uses a plastic nest box to hold the bare syringe for high-pressure steam sterilization. The nest box has a groove that precisely matches the shape of the bare PFS. However, after adding the injector, the overall width and thickness of the pre-filled syringe flange increases, making it impossible to put it back into the original nest box. Directly stacking the syringes for sterilization can lead to problems such as deformation of the injector and plunger under pressure, label adhesion and detachment, uneven stress on the syringe barrel, and incomplete steam penetration leading to sterilization dead zones.
[0003] When the pre-filled syringe is fitted with a significantly enlarged booster and the rod is turned, the nest box designed for bare PFS cannot accommodate the PFS assembly with the booster. The protruding part of the booster cannot fit into the groove of the original nest box, causing the assembly to be unable to be inserted smoothly or not inserted at all. Utility Model Content
[0004] This invention provides a sterilization support device for a pre-filled syringe with a booster, which solves the problem that existing pre-filled syringes cannot be stably placed into the groove of the nest box after being equipped with a booster.
[0005] This utility model provides a sterilization carrier device for a pre-filled syringe with a booster, comprising:
[0006] Support components;
[0007] A fixing plate is disposed on the upper part of the support assembly. The fixing plate has a plurality of lateral opening channels spaced apart along its own length direction. The lateral opening channels form an opening on one side of the fixing plate. Both opposite sidewalls of the lateral opening channels are provided with gaps extending along the width direction of the fixing plate. The openings are used to allow the pre-filled syringe to enter the lateral opening channels, and the gaps are used to allow the booster to be engaged.
[0008] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, wherein each of the lateral opening channels has the same width and the same length, and the width of the lateral opening channel is 9-15 mm.
[0009] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, wherein each of the gaps has the same height, and the height of the gap is 4-8mm.
[0010] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, wherein the support assembly includes:
[0011] Two support plates are spaced apart, and the upper parts of the two support plates are connected to the two ends of the fixing plate one-to-one.
[0012] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, wherein the support plate and the fixing plate are both made of polycarbonate.
[0013] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, the sterilization support device further includes:
[0014] A limiting component is disposed on one side of the fixing plate, and the limiting component is used to limit the pre-filled syringe in the lateral opening channel.
[0015] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, wherein the limiting component includes:
[0016] Two fasteners are provided on the upper part of the two support plates in a one-to-one correspondence;
[0017] A limiting rod, the two ends of which are connected to the two fixing members one by one.
[0018] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, wherein the limiting rod is detachably connected to the fixing member.
[0019] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, wherein a first connecting part is provided on the upper edge of the support plate and a second connecting part is provided on the lower edge of the support plate; when multiple sterilization support devices are stacked together in the vertical direction, the first connecting part is used to connect with the second connecting part of the sterilization support device in the upper layer.
[0020] According to the present invention, a sterilization support device for a pre-filled syringe with a booster is provided, wherein one of the first connecting part and the second connecting part is a stacked protruding ridge, and the other of the first connecting part and the second connecting part is a stacked groove.
[0021] This invention provides a sterilization support device for pre-filled syringes with boosters. By providing multiple lateral opening channels spaced along the length of a fixed plate, and gaps in the sidewalls of these channels, the pre-filled syringe can enter the lateral opening channels through the openings, allowing the booster to engage within the gaps. This achieves stable fixation of the pre-filled syringe with booster on the sterilization support device, successfully solving the problem that traditional nesting boxes cannot accommodate pre-filled syringes with boosters.

[0034] The following is combined Figures 1-4 This invention describes the structural schematic diagram of a sterilization support device for a pre-filled syringe with a booster according to the present invention.
[0035] Figure 1 This is a structural schematic diagram of the sterilization support device for a pre-filled syringe with a booster provided by this utility model. Figure 2 This is a schematic diagram of the sterilization support device for a pre-filled syringe with a booster, provided by this utility model, after removing the limiting rod. Figure 1 and Figure 2 As shown, the sterilization support device for a pre-filled syringe with a booster includes a support assembly 10 and a fixing plate 20. The fixing plate 20 is disposed on the upper part of the support assembly 10. The fixing plate 20 has a plurality of lateral opening channels 21 spaced apart along its own length direction. The lateral opening channels 21 form an opening on one side of the fixing plate 20. The two opposite sidewalls of the lateral opening channels 21 are provided with gaps 22 extending along the width direction of the fixing plate 20. The openings are used to allow the pre-filled syringe to enter the lateral opening channels 21, and the gaps 22 are used to allow the booster to be engaged.
[0036] This invention provides a sterilization support device for pre-filled syringes with boosters. By providing multiple lateral opening channels 21 spaced along the length of a fixed plate 20, and gaps 22 on the side walls of these channels 21, the pre-filled syringe can enter the lateral opening channels 21 through the openings, allowing the booster to engage within the gaps 22. This ensures the pre-filled syringe with booster is stably fixed on the sterilization support device, successfully solving the problem that traditional nesting boxes cannot accommodate pre-filled syringes with boosters. The multiple lateral opening channels 21 and gaps 22 form a sterilization medium flow channel, ensuring that the sterilization medium (steam, gas, radiation) can uniformly, fully, and without dead angles contact the product surface, achieving excellent sterilization results.
[0037] In one embodiment of this utility model, such as Figure 1As shown, each lateral opening channel 21 has the same width and length. The width of each lateral opening channel 21 is 9-15 mm, allowing the sterilization support device to accommodate pre-filled syringes of different specifications, thus enhancing the versatility of the sterilization support device. Preferably, the width of the lateral opening channel 21 is 12 mm. A 12 mm width lateral opening channel 21 not only meets the placement requirements of different models of pre-filled syringes but also ensures sufficient space within the lateral opening channel 21 for the flow of sterilization media, further improving the sterilization effect. Multiple lateral opening channels 21 divide the fixing plate 20 into multiple sections. The length of each lateral opening channel 21 is less than the width of the fixing plate 20, allowing multiple fixing plate units to be connected as a single unit on the other side of the fixing plate 20.
[0038] Preferably, the fixing plate 20 is provided with 10 lateral opening channels 21, each lateral opening channel 21 can hold 10 pre-filled syringes with boosters, and a sterilization carrier can hold 100 pre-filled syringes with boosters.
[0039] In one embodiment of this utility model, such as Figure 1 As shown, gaps 22 divide the fixing plate unit into upper and lower plates. The height of gap 22 is greater than the thickness of the booster's wing, ensuring that the booster can smoothly fit into the gap 22. Each gap 22 has the same height, ranging from 4-8 mm, to accommodate different booster models, enhancing the versatility of the sterilization support device. Preferably, the height of gap 22 is 6 mm. A 6 mm gap 22 not only meets the insertion requirements of different booster models but also ensures sufficient space within the gap 22 for the sterilization medium to flow, ensuring that the sterilization medium can uniformly and fully contact the surface of the pre-filled syringe, thereby achieving a good sterilization effect.
[0040] After the two wings of the booster are engaged in the corresponding gap 22, the pre-filled syringe with the booster is in an inverted loading position. The inverted loading ensures that the condensate generated during the high-pressure steam sterilization and cooling process can be discharged smoothly, effectively preventing the accumulation of condensate inside the syringe, thereby preventing bacterial growth and ensuring the sterile state of the pre-filled syringe after sterilization.
[0041] The sterilization support device for pre-filled syringes with boosters provided by this utility model features multiple lateral opening channels 21 spaced along the length of a fixed plate 20, with gaps 22 on the sidewalls of these channels. This allows the pre-filled syringe to enter the lateral opening channel 21 through the openings, while the booster is securely engaged within the gaps 22. This achieves stable fixation of the pre-filled syringe with booster on the sterilization support device, successfully solving the problem that traditional nesting boxes cannot accommodate PFS (Pre-filled Freeform) components with boosters. It also avoids the problem of unstable placement or inability to fit the nesting box due to the increased size of the booster, thereby improving the feasibility and reliability of sterilization.
[0042] Multiple lateral openings 21 and gaps 22 together form a highly efficient sterilization medium flow channel. This design not only ensures that the sterilization medium (such as steam, gas, radiation, etc.) can uniformly and fully penetrate and contact all surfaces of the pre-filled syringe, but also effectively eliminates sterilization dead zones. By optimizing the flow path of the sterilization medium, the uniformity and thoroughness of the sterilization effect are significantly improved, ensuring the stability of sterilization quality.
[0043] In one embodiment of this utility model, such as Figure 1 As shown, the support assembly 10 includes two support plates 11. The two support plates 11 are identical in size and shape, and are spaced apart. The two support plates 11 are vertically and parallel, and their upper parts are connected to the two ends of the fixed plate 20 respectively. The support of the support plates 11 keeps the fixed plate 20 at a predetermined height, forming a fixed-height interlayer gap below the fixed plate 20, allowing the syringe to suspend in the air. The bottom of the plunger is not subjected to force, and the only point of force is the booster.
[0044] In one embodiment of this utility model, both the support plate 11 and the fixing plate 20 are made of polycarbonate. The polycarbonate support plate 11 and fixing plate 20 have advantages such as high transparency, good mechanical strength, good heat resistance, dimensional stability, non-toxicity, and safety and environmental friendliness. The polycarbonate support plate 11 and fixing plate 20 can withstand multiple sterilization cycles, have a long service life, and effectively reduce costs.
[0045] In one embodiment of this utility model, such as Figure 1 As shown, the sterilization support device also includes a limiting component 30, which is disposed on one side of the fixed plate 20. The limiting component 30 is used to limit the pre-filled syringe within the lateral opening channel 21. By providing the limiting component 30 on one side of the fixed plate 20, the limiting component 30 can ensure that the pre-filled syringe maintains a stable position during the sterilization process, preventing the syringe from shifting or slipping due to equipment vibration or improper operation, thereby ensuring the smooth progress of the sterilization process.
[0046] In one embodiment of this utility model, such as Figure 1 As shown, the limiting assembly 30 includes two fixing members 31 and a limiting rod 32. The two fixing members 31 are correspondingly disposed on the upper part of the two support plates 11, and are at the same height. The fixing members 31 are used to fix the limiting rod 32. The limiting rod 32 is horizontally disposed, at the same height as the opening, and its two ends are connected to the two fixing members 31 respectively. A single limiting rod 32 can limit the pre-filled syringes in all lateral opening channels 21, greatly reducing the number of limiting mechanisms and lowering the complexity and manufacturing cost of the sterilization support device. Using the limiting rod 32 also facilitates quick installation and removal of pre-filled syringes by operators, improving work efficiency. Simultaneously, it reduces potential failure points caused by multiple limiting mechanisms, improves the reliability and stability of the sterilization support device, reduces maintenance workload and time, and further enhances the overall efficiency and safety of the sterilization process.
[0047] In one embodiment of this utility model, the limiting rod 32 is detachably connected to the fixing member 31. Specifically, both ends of the limiting rod 32 are provided with through holes or bayonets, with the through holes fitting onto the fixing member 31 or the bayonets engaging with the fixing member 31. The detachable connection between the limiting rod 32 and the fixing member 31 makes the installation and disassembly of the limiting rod 32 extremely convenient. Operators can quickly complete the assembly or disassembly of the limiting rod 32 without using complex tools or performing cumbersome procedures, greatly improving production efficiency.
[0048] In one embodiment of this utility model, such as Figure 1 As shown, a first connecting portion 12 is provided on the upper edge of the support plate 11, and a second connecting portion 13 is provided on the lower edge of the support plate 11. When multiple sterilization carriers are stacked sequentially in the vertical direction, the first connecting portion 12 is used to connect with the second connecting portion 13 of the upper layer sterilization carrier. The first connecting portion 12 and the second connecting portion 13 effectively improve the stability of the sterilization carriers during the stacking process, allowing multiple sterilization carriers to be tightly and securely connected together. This prevents the stacked devices from shifting or tipping over due to vibration or external forces during sterilization, thus ensuring the smooth progress of the sterilization process. Furthermore, this stacking design results in a small space occupation after the sterilization carriers are stacked, making full use of the limited space inside the sterilization cabinet and significantly improving the utilization rate of the sterilization cabinet.
[0049] In one embodiment of this utility model, such as Figure 3 and Figure 4As shown, the first connecting part 12 is a stacking protrusion extending along the length of the support plate 11, and the second connecting part 13 is a stacking groove extending along the length of the support plate 11. The cross-sectional dimensions and shape of the stacking groove are adapted to the cross-sectional dimensions and shape of the stacking protrusion. When multiple sterilization carriers are stacked together in the vertical direction, the stacking protrusion engages with the stacking groove, thus connecting adjacent sterilization carriers.
[0050] The following is combined with Figures 1 to 4 A specific embodiment of this utility model is described, such as... Figures 1 to 4 As shown, this embodiment uses a common 2.25mL glass PFS with a booster as an example. Both the support plate 11 and the fixing plate 20 are made of medical-grade polycarbonate. The sterilization support device is 450mm long, 250mm wide, and 150mm high. The upper and lower plates are both 2mm thick, and the gap between them is 6mm. The width of the lateral opening channel 21 is 12mm, slightly larger than the diameter of the pre-filled syringe. The diameter of the 2.25mL pre-filled syringe is 11mm, and the distance between two adjacent lateral opening channels 21 is 3cm.
[0051] The limiting assembly 30 includes two fixing members 31 and a limiting rod 32. The two fixing members 31 are correspondingly disposed on the upper part of the two support plates 11, and the two fixing members 31 are at the same height. The fixing members 31 are used to fix the limiting rod 32. The limiting rod 32 is horizontally disposed, and the limiting rod 32 is at the same height as the opening. The length of the limiting rod 32 is 450mm. Both ends of the limiting rod 32 are provided with a locking slot, which is engaged with the fixing member 31.
[0052] Instructions for use of sterilization carrier devices for pre-filled syringes with boosters:
[0053] 1. With the needle end of the pre-filled syringe with the push rod and booster installed facing upward, slide it into the lateral opening channel 21 through the opening. Insert the two wings of the booster into the corresponding gaps 22. Each lateral opening channel 21 can hold 10 syringes, and each sterilization carrier can hold 100 syringes.
[0054] 2. After the syringe is installed in place, lock the two ends of the limiting rod 32 into the fixing part 31.
[0055] 3. Place the needle with the tip facing upwards into the sterilizer for sterilization. Stack multiple sterilization carriers together in the vertical direction. The number of sterilization carriers should be determined according to the height of the sterilizer.
[0056] 4. Place the stacked sterilization carriers into a sterilization trolley or tray and send them into a sterilization cabinet (such as a high-pressure steam sterilizer) for final sterilization. The sterilization medium (saturated steam) can flow freely through the gaps between the layers.
[0057] After sterilization, the device is cooled and then transferred to a clean environment (such as RABS).
[0058] At subsequent packaging stations (such as paper-plastic bags, blister boxes, etc.), the limiting rod 32 can be removed, and the PFS component in the sterilization carrier device can be directly taken out and placed into the final packaging. The empty device can be recycled, cleaned, sterilized, and reused.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
