[0030] Example

[0031] A labeling bottle for radioactive medicine comprises a bottle body 1, a sealing plug 5 is threadedly connected to the bottle mouth 4 at the top of the bottle body 1, the bottle body 1 has a accommodating cavity 18 for placing the radioactive medicine inside, the sealing plug 5 is made of elastic material and has an air inlet pipe 12 and a material guide pipe 3 at its bottom, the bottom end of the material guide pipe 3 extends to the bottom wall of the accommodating cavity 18 but does not touch it, the air pipe is at the upper end of the bottle body 1, and the sealing plug 5 is provided with an air inlet channel 9 and a material guide channel 6 respectively connected to the air inlet pipe 12 and the material guide pipe 3, the cross-section of the air inlet channel 9 and the material guide channel 6 is a cone shape with a larger upper end and a smaller lower end, and an aluminum foil sealing sheet 8 is fixed at the inlet of the air inlet channel 9 and the material guide channel 6 for sealing.

[0032] In this embodiment, Figure 1As shown, the air inlet pipe 12 and the material guide pipe 3 are directly arranged inside the bottle body 1, and the air inlet pipe 12 and the material guide pipe 3 are connected to the sealing plug 5 made of elastic material, and the sealing plug 5 is connected by threads. This connection method is convenient for disassembly and can ensure the sealing of the bottle body 1 to prevent leakage of radioactive drugs. The sealing plug 5 is made of elastic material, which enables it to better fit closely with the bottle mouth 4 to prevent gas or liquid leakage. Figure 2 and Figure 3 As shown, an air inlet channel 9 and a material guide channel 6 which are respectively connected to the air inlet pipe 12 and the material guide pipe 3 are opened inside the sealing plug 5. The inlet ends of the air inlet channel 9 and the material guide channel 6 are sealed with an aluminum foil seal 8 to prevent the internal radioactive agent from overflowing. The inlet ends of the air inlet channel 9 and the material guide channel 6 are fixed with an aluminum foil seal 8 for sealing. The aluminum foil seal 8 can effectively prevent external impurities from entering the channel, thereby ensuring the cleanliness of the inside of the channel and the purity of the agent. When it is necessary to use the radioactive medicine in the bottle 1, the external pipe is directly pierced through the aluminum foil seal 8. There are two external pipes 13, and the lower ends of the external pipes 13 can be set to be sharp, so that it is easier to pierce the aluminum foil seal 8. After piercing the aluminum foil seal 8, the two external pipes 13 are further inserted downward into the air inlet channel 9 and the material guide channel 6 respectively, so that the corresponding external pipes are connected with the air inlet pipe 12 and the material guide pipe 3, and the cross-section of the air inlet channel 9 and the material guide channel 6 is a cone shape with a large upper end and a small lower end. The further the external pipe 13 is inserted downward, the stronger the sealing between it and the air inlet channel 9 and the material guide channel 6. In this way, during use, air will not overflow from the sealing plug 5. After the air enters the accommodating cavity 18 through the air inlet pipe 12, the radioactive medicine inside is pressed out from the material guide pipe 3 to the outside for use. During use, no other hard objects are needed to pierce the sealing plug 5. The external pipe 13 can directly pierce the fragile aluminum foil seal 8. The use process is simple and quick, which improves work efficiency. At the same time, according to actual needs, a syringe connector 19 for matching with a syringe is also provided on the sealing plug 5. The syringe injects the required medicine into the bottle through the connector. The syringe connector 19 is an existing product.

[0033] Furthermore, the bottle body 1 has a filling cavity in its side wall, and the filling cavity is filled with a shielding layer 2 .

[0034] Furthermore, the material of the shielding layer 2 includes but is not limited to lead, iron and tungsten steel.

[0035] Specifically, Figure 1As shown, a filling cavity is designed inside the side wall of the bottle body 1, and a shielding layer 2 is filled in the filling cavity. Its main function is to block or weaken the radiation generated by the radioactive drug, thereby protecting the safety of the user and the surrounding environment. This design is particularly suitable for occasions where radioactive drugs need to be stored or transported for a long time, and can effectively reduce the risk of radiation leakage. Lead, iron and tungsten steel are all common radiation shielding materials. These materials have high density and good absorption capacity, and can effectively absorb and block the radiation generated by radioactive drugs. Using these materials as the shielding layer 2 can greatly improve the radiation protection performance of the marking bottle. "Including but not limited to" lead, iron and tungsten steel, the material of the shielding layer 2 is not limited to these three. In practical applications, the most suitable shielding material can be selected according to factors such as specific radiation sources, radiation intensity and usage scenarios. This design flexibility provides a broader space for the application of marking bottles. In summary, by setting a filling cavity in the side wall of the bottle body 1 and filling the shielding layer 2, and selecting a variety of suitable shielding materials, the safety of the marking bottle of this radioactive drug has been greatly improved. This design not only takes into account the characteristics of the radioactive drug, but also fully considers the safety needs of the user and the surrounding environment. It is a very practical and safe design solution.

[0036] Furthermore, the sealing plug 5 is T-shaped, and its material includes but is not limited to rubber and silicone.

[0037] Specifically, the design of the T-shaped sealing plug 5 can ensure a close fit with the bottle mouth 4, providing a better sealing effect, and the T-shaped structure can be more stably fixed on the bottle mouth 4 to prevent leakage of the medicine or entry of foreign impurities. The rubber material has good elasticity and sealing performance, which can effectively prevent the leakage of radioactive medicines. At the same time, the rubber material also has a certain aging resistance, which can ensure that the sealing plug 5 can still maintain its good sealing effect during long-term use. The silicone material also has excellent elasticity and sealing performance, and it also has good high temperature resistance, which makes the silicone sealing plug 5 still stable in a high temperature environment, ensuring the safe storage and transportation of medicines. In addition, silicone also has the characteristics of non-toxicity, odorlessness, and good insulation performance, so that it is also widely used in medical, food and other fields. In summary, the T-shaped design and the selection of rubber and silicone materials make this sealing plug 5 have excellent sealing performance and safety performance in the labeling bottle of radioactive medicines, which can meet the needs of long-term storage and transportation. At the same time, these materials also have good durability and stability, which can ensure that the sealing plug 5 always maintains its good performance during use.

[0038] Furthermore, the edge of the bottle mouth 4 of the bottle body 1 is integrally formed with a folded edge 11 extending outward. Specifically, the design of the folded edge 11 makes the edge of the bottle mouth 4 more solid and less prone to deformation. This design of enhancing structural stability helps to ensure a more stable connection between the bottle body 1 and the sealing plug 5, reducing the risk of loosening or leakage caused by external impact or vibration. The folded edge 11 is also for matching the T-shaped sealing plug 5.

[0039] like Figure 4 As shown, further, a locking ring 10 for tightening the sealing plug 5 is sleeved on the outside of the sealing plug 5 , and the middle of the locking ring 10 is a hollow area 16 , and the aluminum foil sealing sheet 8 is located in the hollow area 16 .

[0040] Specifically, the design of the locking ring 10 enables the sealing plug 5 to fit more closely on the bottle mouth 4, thereby enhancing the overall sealing effect, which is crucial to preventing the leakage of radioactive drugs and ensuring the safety of the labeled bottles during storage and transportation. The hollow area 16 in the middle of the locking ring 10 is cleverly designed, which makes the position of the aluminum foil seal 8 clear at a glance. When the aluminum foil seal 8 needs to be destroyed to use or check the channel, the user can directly operate through the hollow area 16 without removing the locking ring 10 or the sealing plug 5, which greatly improves the convenience of operation. The use of the locking ring 10 and the sealing plug 5 not only enhances the sealing effect, but also improves the stability of the entire bottle mouth 4 structure. Even in the case of external impact or vibration, the sealing plug 5 can maintain a stable position and is not easy to loosen or fall off. The safety of the marked bottle is further improved through the dual protection of the locking ring 10 and the aluminum foil seal 8. The aluminum foil seal 8 can effectively prevent external impurities from entering the channel, while the locking ring 10 ensures the stability of the sealing plug 5. The two work together to provide a strong guarantee for the safe storage and transportation of radioactive drugs.

[0041] Furthermore, the locking ring 10 is C-shaped, with an opening on the right side. The cross section of the locking ring 10 is U-shaped, and the sealing plug 5 and the folded edge 11 are embedded in the U-shaped cavity.

[0042] Specifically, the locking ring 10 is C-shaped and has an opening on the right side. This design allows the locking ring 10 to be easily sleeved on the outside of the sealing plug 5 and fine-tuned through the opening to adapt to sealing plugs 5 or bottle mouths 4 of different sizes. The presence of the opening not only facilitates the installation and removal of the locking ring 10, but also makes the locking ring 10 have a certain degree of elasticity, which can better adapt to the shape and size of the bottle mouth 4 and ensure the tight fit of the sealing plug 5. Figure 6As shown, the cross section of the locking ring 10 is U-shaped. The U-shaped cavity provides enough space for the sealing plug 5 and the folded edge 11 so that they can be fully embedded therein. When the locking ring 10 is pressed, the two sides of the U shape will tightly clamp the sealing plug 5 and the folded edge 11 to form a solid barrier, effectively preventing the leakage of radioactive drugs. Through the combination of the C-shaped design and the U-shaped cross section, the locking ring 10 can fit tightly on the bottle mouth 4 and the sealing plug 5 to form a reliable sealing structure. This design not only improves the sealing performance between the sealing plug 5 and the bottle mouth 4, but also enhances the structural stability of the entire marking bottle, so that the marking bottle can better resist external impact and vibration during transportation and use. The design of the C-shaped opening makes it easier to install and remove the locking ring 10. The user can easily put the locking ring 10 on the sealing plug 5 and adjust the size of the opening to adapt to different installation requirements. This design reduces the difficulties that may occur during the installation process and improves the convenience of operation.

[0043] Furthermore, a fixing plate 15 is provided at the open end on the right side of the locking ring 10, a threaded hole is provided on the side of the fixing plate 15, a locking bolt 14 is threadedly connected to the threaded hole, and the locking bolt 14 is screwed to change the locking degree of the locking ring 10 on the sealing plug 5.

[0044] Specifically, a fixing plate 15 is provided at the open end on the right side of the locking ring 10, and a threaded hole is provided on the side of the fixing plate 15, providing a stable installation foundation for the locking bolt 14. This design enables the locking bolt 14 to be firmly fixed on the fixing plate 15, thereby ensuring that the locking ring 10 can work stably when the locking bolt 14 is screwed. The locking bolt 14 is threadedly connected in the threaded hole, and its function is to adjust the locking degree of the locking ring 10 on the sealing plug 5. By screwing the locking bolt 14, the user can accurately control the tightness of the locking ring 10 as needed, thereby ensuring that the sealing performance between the sealing plug 5 and the bottle mouth 4 reaches the best state. This design makes the locking of the sealing plug 5 by the locking ring 10 more accurate and reliable. By fine-tuning the locking bolt 14, the small gap caused by manufacturing error or improper installation can be eliminated, and the sealing performance between the sealing plug 5 and the bottle mouth 4 can be further improved, which is crucial to prevent the leakage of radioactive drugs and ensure the safety and reliability of the labeled bottle. At the same time, the sealing plug 5 can be squeezed when the locking bolt 14 is screwed. The sealing plug 5 is made of rubber. In this way, squeezing the sealing plug 5 can make the air intake channel 9 and the material guide channel 6 more tightly wrapped around the external pipeline 13, and the sealing performance is also stronger.

[0045] Furthermore, a protective cover 7 is provided in the hollow area 16. Specifically, Figure 5As shown, the protective cover 7 can be directly bonded to the top surface of the guide plug 5, and the upper ends of the air inlet channel 9 and the material guide channel 6 can be sunken, so that the aluminum foil seal 8 will not contact the bottom surface of the protective cover 7, and the integrity of the aluminum foil seal 8 will not be affected when the protective cover 7 is torn off. At the same time, in order to facilitate the tearing off of the protective cover 7, a tear strip 17 can be set on the side of the protective cover 7. The main function of the protective cover 7 is to protect the aluminum foil seal 8 located in the hollow area 16 to prevent it from being physically damaged or contaminated by the outside during transportation, storage or use. The integrity of the aluminum foil seal 8 is a key sealing component and is crucial to ensure the safe closure of the channel. By covering the aluminum foil seal 8, the protective cover 7 can also prevent users or operators from accidentally touching or damaging the aluminum foil seal 8 when it is not needed, thereby ensuring the safety of the labeled bottle during normal use.

[0046] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
