Description

Technical Field

[0001] This utility model belongs to the field of injectable drug testing technology, specifically relating to a tooling for testing visible foreign matter in small-volume injectables. Background Technology

[0002] Injectable drugs undergo rigorous visual inspection during production to eliminate substandard products containing visible foreign matter, ensuring medication safety. Currently, the industry commonly uses manual visual inspection, where operators hold only a small number of ampoules (usually 3-5) at a time, gently rotating them repeatedly with their wrists at the inspection station to suspend and move potential visible foreign matter within the solution for visual inspection. Because the number of injections inspected per batch is small, overall efficiency is low, and the high-intensity repetitive operation easily leads to operator fatigue, increasing the risk of missed inspections and affecting the stability of quality control and production efficiency. Therefore, there is an urgent need for inspection fixtures adapted to the characteristics of small-volume injectable drug visual inspection, to increase the number of ampoules inspected per batch, reduce operator workload, and minimize the risk of missed inspections. Utility Model Content

[0003] This invention addresses the shortcomings of the prior art by providing a tooling for inspecting visible foreign matter in small-volume injectables. By increasing the number of samples that can be inspected at one time, it improves inspection efficiency, reduces the labor intensity of operators, and minimizes the risk of missed inspections due to operator fatigue.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A tooling for inspecting visible foreign matter in small-volume injectables includes a top plate and a bottom plate arranged in parallel. A background plate is connected between the top plate and the bottom plate. The bottom of the top plate is provided with a light source and a suspension bracket for suspending ampoules. The suspension bracket includes a hanger and a crossbeam. The crossbeam is rotatably connected to the hanger. The crossbeam is a hollow structure with openings at both ends, and its bottom is provided with a groove that matches the neck of the ampoule. The crossbeam is provided with a fixing component for clamping the ampoule.

[0005] Preferably, the base plate is provided with a support component for supporting the operator's wrist.

[0006] Preferably, the support assembly includes a support column, a support plate, and an elastic pad. The lower end of the support column is connected to the base plate, and the upper end is connected to the support plate. The elastic pad is disposed at the top of the support plate.

[0007] Preferably, the base plate is provided with a support seat, and the support column is threadedly connected to the support seat.

[0008] Preferably, the fixing component includes multiple sets of through slots spaced apart along the length of the beam and T-shaped inserts that mate with the slots.

[0009] Preferably, the inner wall of the slot is provided with an elastic washer.

[0010] Preferably, the hanger includes a hanger rod and two support rods, with the two support rods symmetrically connected to the lower ends of the hanger rod on both sides.

[0011] Preferably, the top of the crossbeam is provided with two sleeves, which are respectively fitted onto two support rods, and the support rods are threadedly connected to the hanger rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves the purpose of light inspection by suspending multiple ampoules sequentially below a crossbeam, gently moving the crossbeam to agitate the liquid in the ampoules, and using a light source to observe potential foreign objects in the liquid. Because the number of injections inspected per light inspection is significantly increased, the efficiency of light inspection is effectively improved, and the frequency and intensity of wrist rotation are greatly reduced, decreasing the risk of missed detection and ensuring the stability of drug quality. At the same time, the support component supports the operator's wrist, further alleviating hand fatigue and reducing labor intensity. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figure 1 As shown, a fixture for inspecting visible foreign matter in small-volume injectables includes a top plate 1 and a bottom plate 2 arranged parallel to each other. A background plate 3 connects the top and bottom plates and is located behind the top plate. A light source 4 and a suspension bracket for suspending ampoules are located at the bottom of the top plate. The light source is an LED lamp, located in front of the suspension bracket, and electrically connected to an external power source to provide light for the lamp inspection of the injectables. The suspension bracket includes a hanger and a crossbeam 5, which are rotatably connected to the hanger. The hanger includes a hanging rod 14 and two support rods 15, which are symmetrically connected to the lower ends of the hanging rod. Two sleeves 16 are located at the top of the crossbeam and are respectively fitted onto the two support rods. By manually moving the crossbeam forward or backward, it can be swung back and forth, causing the liquid in the ampoule to shake, facilitating observation. The support rods and hanging rods are threaded together, facilitating the disassembly and assembly of the crossbeam and the hanger, and simplifying maintenance.

[0019] like Figure 1 and Figure 3 As shown, the crossbeam is a hollow structure with openings at both ends, and its bottom has a slot 6 that matches the neck of the ampoule. Operators can arrange batches of small-volume injection solutions (ampoules) sequentially in the slot. Utilizing the structural feature that the outer diameter of the ampoule's neck is smaller than its upper head, the ampoule is suspended from the lower end of the crossbeam. The crossbeam is equipped with a fixing component for clamping the ampoules, which prevents the placed ampoules from slipping off the end of the crossbeam. Combined with... Figure 2As shown, the fixing assembly includes multiple sets of through slots 11 spaced along the length of the crossbeam, and T-shaped inserts 12 that mate with the slots. The appropriate slot is selected based on the number of ampoules. When the T-shaped insert is inserted into the corresponding slot, the ampoule is simply positioned. An elastic washer 13 is provided on the inner wall of the slot to increase the friction between the T-shaped insert and the slot, preventing the T-shaped insert from falling out. The operator only needs to use their hand to swing the crossbeam forward from the rear side to achieve the same purpose as traditional wrist rotation for suspending and moving potentially visible foreign objects in the medication. Visual inspection can then be performed using a light source. Because the number of injections that can be inspected in a single light inspection is significantly increased, the efficiency of light inspection is effectively improved, and the frequency and intensity of wrist rotation are greatly reduced, reducing the risk of missed inspections and ensuring the stability of drug quality.

[0020] like Figure 1 As shown, to further alleviate operator hand fatigue, the base plate is equipped with a support assembly for supporting the operator's wrists. The support assembly includes a support column 7, a support plate 8, and an elastic pad 9. The lower end of the support column is connected to the base plate, and the upper end is connected to the support plate. The elastic pad is located at the top of the support plate. The base plate is equipped with a support seat 10, and the support column and the support seat are threaded together. This facilitates disassembly, assembly, and maintenance.

[0021] The method of using this utility model is as follows: like Figure 1 As shown, when inspecting small-volume injectable solutions for visible foreign matter, the operator first arranges multiple ampoules 17 tightly on the crossbeam 5. Utilizing the neck structure of the ampoules 17, they are suspended on the crossbeam 5. Based on the number and position of the ampoules 17, two T-shaped inserts 12 are inserted into the corresponding slots 11 on both sides to achieve simple positioning of the ampoules 17, preventing them from sliding significantly along the length of the crossbeam 5. Then, the operator presses their wrist against the elastic pad 9 and gently moves the crossbeam 5 from back to front, causing the liquid inside the ampoules 17 to slosh. Using a light source, the operator observes whether there are any foreign objects in the liquid.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
