Description

Technical Field

[0001] This utility model relates to the field of vial technology, specifically to a puncture-proof protective device for vials. Background Technology

[0002] A vial, also known as a borosilicate glass or soda-lime glass molded injection vial, is a small bottle sealed with a rubber stopper and an aluminum-plastic composite cap. It is a common packaging bottle for injectable vaccines, biological agents, and powder injections. Early penicillin was often contained in these vials, hence the name "vials." The neck is narrower, and the width is uniform below the neck. The mouth is slightly wider than the neck and slightly narrower than the body. It is generally used for packaging vaccines, biological agents, powder injections, and lyophilized drugs.

[0003] When medical staff use vials to prepare medications, they need to pry open the aluminum-plastic combination cap on the bottle opening to expose the rubber stopper inside. This step usually requires the cooperation of both hands and requires proper axial control during operation to prevent slippage due to deviation, thereby ensuring the accuracy and safety of the operation.

[0018] This utility model provides the following technical solution: Example 1 Combination Figures 1 to 4A puncture-proof protective device for vials includes a protective sleeve 1, a vial 4, and an elastic rubber ring 5. There are two protective sleeves 1. The protective sleeve 1 is disposed on the surface of the vial 4. An anti-slip sleeve 2 is fixedly connected to the surface of the protective sleeve 1. An elastic rubber ring 5 is fixedly connected to the upper end of the inner wall of the protective sleeve 1. A connecting mechanism 3 is provided on the two protective sleeves 1. A protective mechanism 6 is provided on the protective sleeve 1. The protective mechanism 6 includes a clamping component 61 and a fixing component 62, with the fixing component 62 disposed on the clamping component 61; The clamping assembly 61 includes a spring 613, which is fixedly connected to the upper and lower ends of the inner wall of the protective sleeve 1. A clamping ring 611 is fixedly connected to the other side of the spring 613. A connecting rod 612 is fixedly connected to the side of the clamping ring 611 near the inner wall of the protective sleeve 1. A frustum 614 is fixedly connected to the other side of the connecting rod 612. The fixing component 62 includes a socket slot 625, in which connecting rods 612 are densely arranged. Limiting seats 622 are fixedly connected to the center of the front and rear sides of the protective sleeve 1. Electric push rods 623 are fixedly connected to the top and bottom of the limiting seats 622. A moving ring 621 is also fixedly connected to the other side of the electric push rod 623. Inserting rods 624 are densely fixedly connected to the outside of the moving ring 621. The protective sleeve 1 has a through hole groove inside, and the surface of the connecting rod 612 is inserted through the through hole groove inside the protective sleeve 1. The frustum 614 is set on the outside of the protective sleeve 1, and the outer diameter of the frustum 614 is larger than the diameter of the through hole groove inside the protective sleeve 1. The top and bottom of the insertion slot 625 are set as openings, and the surface of the insertion rod 624 is inserted into the insertion slot 625. There are four moving rings 621, which are arranged in pairs. Two moving rings 621 are set on the top and bottom of the anti-slip sleeve 2.

[0019] Furthermore, the insert plate 37 is inserted into the slot 36, and the locking block 34 is locked into the slot 35, so that the two protective sleeves 1 can be combined and installed. The protective sleeve 1 is made of puncture-resistant high-strength material, such as special engineering plastic or metal alloy, which can tightly wrap the vial 4. The vial 4 is inserted into the protective sleeve 1 from top to bottom. At the same time, the elastic rubber ring 5, with its high elasticity, makes the vial 4 automatically tighten after insertion to prevent it from falling out.

[0020] Example 2 See Figure 1-6Furthermore, based on Embodiment 1, the connecting mechanism 3 further includes a connecting seat 31, which is fixedly connected to the front and rear surfaces of the protective sleeve 1. A slot 36 is provided inside the connecting seat 31, and the left and right sides of the slot 36 are set as openings. An insert plate 37 is inserted into the slot 36, and a slot 35 is provided inside the left and right sides of the insert plate 37. A hinge plate 32 is fixedly connected to the upper outer side of the two connecting seats 31. A locking plate 33 is hinged to the other side of the hinge plate 32. A locking block 34 is fixedly connected to the side of the locking plate 33 near the insert plate 37. The openings of the slots 35 on the left and right sides are correspondingly opened, and the surface of the locking block 34 and the inside of the slot 35 are engaged.

[0021] Furthermore, the rebound force of the spring 613 drives the clamping ring 611 to clamp and fix the vial 4. At the same time, the connecting rod 612 is stretched, and the electric push rod 623 drives the moving ring 621 to move. The moving ring 621 drives the insertion rod 624 to be inserted into the insertion slot 625, which can limit and fix the position of the clamping ring 611. It can be adjusted according to the size of the vial 4 and firmly fixed.

[0022] In actual operation, when this device is used and the vial 4 needs to be used, the two protective sleeves 1 can be assembled by inserting the insert plate 37 into the slot 36, and then rotating the locking plate 33 on the hinge plate 32 side again, so that the locking plate 33 can drive the locking block 34 to engage in the slot 35, and the two protective sleeves 1 can be combined and installed. The protective sleeve 1 is made of puncture-resistant high-strength material, such as special engineering plastic or metal alloy, which can tightly wrap the vial 4. The vial 4 is inserted into the protective sleeve 1 from top to bottom. At the same time, the elastic rubber ring 5, with its high elasticity, makes the vial 4 automatically tighten after insertion to prevent it from falling out. Once the protective sleeve 1 is placed on the surface of the vial 4, the clamping ring 611 can be driven by the rebound force of the spring 613 to clamp and fix the vial 4. At the same time, the connecting rod 612 is stretched, and the moving ring 621 is moved by the operation of the electric push rod 623. The moving ring 621 drives the insertion rod 624 to be inserted into the insertion slot 625, which can limit and fix the position of the clamping ring 611. It can be adjusted according to the size of the vial 4 and is firmly fixed. The surface of the anti-slip sleeve 2 has anti-slip texture for easy gripping. At the same time, a warning label area can be set as needed to facilitate the labeling of important information about the medicine.
