Description

Technical Field

[0001] This utility model relates to the field of vial protection technology, specifically a vial mouth protection structure. Background Technology

[0002] Due to their excellent sealing properties, chemical stability, and ease of aseptic operation, vials are widely used for the packaging and storage of high-value or perishable reagents such as biological reagents, standards, lyophilized powders, enzyme solutions, and antibodies. In actual use, many reagents are packaged in multiple doses, meaning that once opened, they need to be used multiple times and cannot be used up at once.

[0003] Insulin injection is a multi-dose formulation, with a single clinical dosage far lower than the packaging specifications. It must be used in multiple doses within the expiration date. In current practice, after removing the aluminum cap of the vial, a disposable infusion patch is often used to cover the puncture site to maintain the sterility of the rubber stopper. However, since multiple punctures are required to retrieve the medication, the infusion patch needs to be repeatedly peeled off and put on, which can easily lead to residual adhesive residue on the surface of the rubber stopper. This not only affects the field of vision and puncture positioning, but may also cause particulate contamination due to the detachment of the adhesive. At the same time, repeated peeling and putting on the patch destroys the sealed environment, significantly increasing the risk of microbial invasion and drug contamination, violating the principles of aseptic operation and posing a potential threat to patient medication safety. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a bottle mouth protection structure that can effectively protect the bottle mouth part.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vial neck protection structure includes a mounting ring with a bottle placement groove at its center. A fixing block is fixedly mounted on the mounting ring, a rotating plate is rotatably mounted on the fixing block, and a cover plate is fixedly mounted on the rotating plate. The mounting ring is provided with a clamping assembly and a driving assembly. An operating protrusion is fixedly mounted on the rotating plate, and a connecting piece is fixedly mounted on the operating protrusion. A limit hole is formed on the connecting piece. The mounting ring is fixedly mounted with a connecting block, and a locking assembly adapted to the limit hole is provided inside the connecting block.

[0007] Preferably, the clamping assembly includes a moving block and a rotating ring. There are multiple moving blocks, which are circumferentially and equidistantly slidably mounted on the mounting ring. The rotating ring is rotatably mounted inside the mounting ring. The rotating ring has a spiral groove on the side facing the moving block, and the moving block has a forward and backward groove on the side facing the rotating ring. The forward and backward groove is adapted to the spiral groove.

[0008] Preferably, sliders are fixedly installed on both sides of the plurality of movable blocks, and the mounting ring has a groove at the corresponding position for the sliders to slide.

[0009] Preferably, a buffer pad is embedded in the side of each of the plurality of movable blocks facing the center of the mounting ring.

[0010] Preferably, the drive assembly includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly mounted on the upper side of the rotating ring, and the second bevel gear is rotatably mounted inside the mounting ring. The first bevel gear and the second bevel gear are meshed. A connecting rod is fixedly mounted at the center of the second bevel gear, and an operating rotary block is fixedly mounted through the mounting ring via the connecting rod.

[0011] Preferably, the locking assembly includes a limiting rod, which is slidably mounted on the connecting block. A sliding piece is fixedly mounted on the limiting rod, and the sliding piece is slidably mounted inside the connecting block. A return spring is mounted on the sliding piece, and the other end of the return spring is mounted on the inner wall of the connecting block. One end of the limiting rod protrudes from the connecting block and is adapted to a limiting hole, while the other end of the limiting rod passes through the connecting block and is fixedly mounted with a toggle piece.

[0012] Preferably, a sealing gasket is embedded in the cover plate at the center position on the side facing the mounting ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model achieves effective sealing of the bottle stopper through the synergistic effect of the cover plate and the sealing gasket. When the cover plate is closed, the sealing gasket on its inner side is tightly attached to the surface of the stopper. The elastic deformation of the sealing gasket fills the tiny gap between the two contact surfaces, which significantly improves the sealing performance and effectively prevents external air, moisture and dust and other pollutants from entering the bottle, thereby providing a good storage environment for the medicine in the bottle and prolonging the stability of the medicine.

[0015] (2) This utility model is equipped with an adjustable clamping component and a reliable locking structure, which has good adaptability and stability of use. By rotating the operating block to drive the bevel gear transmission system, the rotating ring is driven to rotate, thereby controlling the three moving blocks to move synchronously radially under the guide of the slide groove. It can adapt to vials of different diameters and achieve uniform and centered clamping force to avoid tilting or breakage of the vials. At the same time, after the cover is closed, it can be automatically fixed by the locking component to prevent accidental opening. The overall structure is easy to operate and firmly clamps, which improves the convenience of use. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1 to 6 A vial neck protection structure includes an installation ring 1 with a bottle placement groove at its center. A fixing block 2 is fixedly installed on the installation ring 1, and a rotating plate 3 is rotatably installed on the fixing block 2. A cover plate 4 is fixedly installed on the rotating plate 3. The vial neck is aligned with the bottle placement groove of the installation ring 1 and placed in, so that the upper surface of the vial is exposed above the upper surface of the rotating plate 3. The rotating plate 3 rotates around the fixing block 2, causing the cover plate 4 to cover the rubber stopper of the vial neck. The direct contact between the cover plate 4 and the rubber stopper achieves a seal, preventing external contaminants from entering the vial.

[0025] The mounting ring 1 is equipped with a clamping component and a driving component, which facilitates the clamping of vials of different diameters, so that the entire device can be stably installed on the vials.

[0026] An operating protrusion 5 is fixedly installed on the cover plate 4, a connecting piece 6 is fixedly installed on the operating protrusion 5, a limit hole 20 is opened on the connecting piece 6, and a connecting block 11 is fixedly installed on the mounting ring 1. A locking component adapted to the limit hole 20 is provided inside the connecting block 11.

[0027] When rotating the cover plate 4, force can be applied by gripping the operating protrusion 5 to make rotation easier. After the cover plate 4 is closed, the limiting hole 20 on the connecting piece 6 aligns with the locking component in the connecting block 11. The locking component automatically or manually engages with the limiting hole 20 to fix the cover plate 4 and prevent it from being opened accidentally.

[0028] like Figure 3 , Figure 4 as well as Figure 5 As shown, the clamping assembly includes a movable block 7 and a rotating ring 16. There are multiple movable blocks 7, which are circumferentially and equidistantly slidably mounted on the mounting ring 1. The rotating ring 16 is rotatably mounted inside the mounting ring 1. A spiral groove 19 is provided on the side of the rotating ring 16 facing the movable block 7, and a forward / backward groove 15 is provided on the side of the movable block 7 facing the rotating ring 16. The forward / backward groove 15 is adapted to the spiral groove 19.

[0029] When the rotating ring 16 rotates within the mounting ring 1, the spiral groove 19 on its side interacts with the infeed groove 15 on the moving block 7. Since the trajectory of the spiral groove 19 is curved, it pushes or pulls the moving block 7 through the infeed groove 15, causing multiple moving blocks 7 to slide synchronously along the radial direction of the mounting ring 1. This allows for the uniform application of clamping force from multiple directions, ensuring clamping stability and centering, and preventing the bottle from tilting or being damaged due to uneven force. Furthermore, the moving blocks 7 can achieve synchronous radial movement through the drive of the rotating ring 16, clamping or releasing the bottle mouth for different diameter vials. Since the cooperation mechanism between the spiral groove 19 and the infeed groove 15 is prior art, it will not be described in detail here.

[0030] like Figure 1 As shown, sliders 8 are fixedly installed on both sides of multiple movable blocks 7, and the mounting ring 1 has a groove 9 at the corresponding position for the sliders 8 to slide.

[0031] When the movable block 7 slides, the sliders 8 on both sides are embedded in the grooves 9 of the mounting ring 1 and slide along the grooves. The grooves 9 guide and limit the sliders 8, preventing the movable block 7 from shifting or shaking during the sliding process, ensuring that the multiple movable blocks 7 are always circumferentially distributed, and stably achieving the clamping action on the bottle mouth.

[0032] like Figure 2 As shown, buffer pads 14 are embedded in the side of the multiple movable blocks 7 facing the center of the mounting ring 1.

[0033] When the movable block 7 clamps the vial, the buffer pad 14 comes into direct contact with the vial body. Its material has a certain degree of elasticity, which can buffer the clamping force and prevent the movable block 7 from rigidly contacting the vial body, thus avoiding wear or breakage of the vial body. At the same time, it increases the friction between the movable block 7 and the vial body, thereby improving the stability of the clamping.

[0034] like Figure 3 , Figure 4 As shown, the drive assembly includes a first bevel gear 17 and a second bevel gear 18. The first bevel gear 17 is fixedly mounted on the upper side of the rotating ring 16, and the second bevel gear 18 is rotatably mounted inside the mounting ring 1. The first bevel gear 17 and the second bevel gear 18 are meshed. A connecting rod 12 is fixedly mounted at the center of the second bevel gear 18. The connecting rod 12 passes through the mounting ring 1 and a rotating block 13 is fixedly mounted thereon.

[0035] It is worth noting that the rotation design of the connecting rod 12 has a certain resistance (which can be achieved through bearing damping, friction plates or interference fit). When the rotating block 13 stops rotating, the resistance can prevent the connecting rod 12 from rotating due to vibration or external force, thereby locking the position of the rotating ring 16, avoiding the moving block 7 from being accidentally loosened, and ensuring the stable clamping state of the clamping assembly on the vial.

[0036] When the clamping assembly needs to be adjusted, the operating block 13 is rotated by hand, which drives the second bevel gear 18 to rotate through the connecting rod 12. Since the first bevel gear 17 and the second bevel gear 18 are meshed, the second bevel gear 18 will drive the first bevel gear 17 to rotate, which in turn drives the rotating ring 16 to rotate within the mounting ring 1, ultimately achieving the sliding adjustment of the moving block 7.

[0037] like Figure 5 , Figure 6 As shown, the locking assembly includes a limiting rod 21, which is slidably mounted on the connecting block 11. A sliding piece 22 is fixedly mounted on the limiting rod 21 and is slidably mounted inside the connecting block 11. A return spring 23 is mounted on the sliding piece 22, and the other end of the return spring 23 is mounted on the inner wall of the connecting block 11. One end of the limiting rod 21 protrudes from the connecting block 11 and is adapted to the limiting hole 20. The other end of the limiting rod 21 passes through the connecting block 11 and is fixedly mounted with a toggle piece 24.

[0038] When the cover plate 4 is locked, the return spring 23 pushes the sliding piece 22, causing one end of the limiting rod 21 to be inserted into the limiting hole 20 of the connecting piece 6, thus completing the locking. When it is necessary to open the cover plate 4, the actuating piece 24 is moved outward, which causes the limiting rod 21 and the sliding piece 22 to stretch the return spring 23, causing the limiting rod 21 to be pulled out of the limiting hole 20. After the lock is released, the cover plate 4 can be rotated. After the actuating piece 24 is released, the return spring 23 automatically resets, causing the limiting rod 21 to return to its initial position.

[0039] like Figure 2As shown, a sealing gasket 10 is inlaid and installed at the center position of the cover plate 4 facing the mounting ring 1.

[0040] When the cover plate 4 is placed on the rubber stopper of the vial, the sealing gasket 10 fits tightly against the surface of the rubber stopper. The elastic deformation of the sealing gasket 10 fills the tiny gaps in the contact surface, further enhancing the sealing effect and effectively preventing air, moisture and dust from entering the vial, thus extending the shelf life of the medicine inside the vial.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
