Description

Technical Field

[0001] This utility model relates to the field of FDG isotope transportation technology, specifically to a protective lead container for FDG isotope transportation. Background Technology

[0002] FDG refers to fluorodeoxyglucose, and the isotope used in fluorodeoxyglucose is fluorine-18 (F18). 18 (F) Fluorine-18 was chosen as the isotope due to its superior physical properties. Its emitted positron energy is moderate (average approximately 250 keV), and its short range in tissues (average approximately 2.4 mm) is advantageous for obtaining high-resolution PET images. Its half-life of approximately 110 minutes is sufficient for radiolabeling, quality control, transportation, and clinical injection and imaging, without prolonged residence in the body, thus reducing the patient's radiation dose. Furthermore, fluorine-18 can be introduced into glucose molecules through nucleophilic or electrophilic substitution reactions, replacing the hydroxyl group (-OH) on the second carbon of glucose, forming... 18 F-FDG. FDG is structurally very similar to glucose and can be taken up by cells (especially hypermetabolic cells such as tumor cells) via glucose transporters (GLUTs). After entering the cell, FDG is phosphorylated to FDG-6-phosphate by hexokinase, but due to the presence of fluorine atoms, it cannot continue to participate in glycolysis and is therefore "retained" inside the cell. This "metabolic trapping" mechanism allows FDG to accumulate highly in hypermetabolic tissues (such as malignant tumors, the brain, and myocardium), facilitating the detection of lesions via PET imaging.

[0003] Applications of FDG include: Oncology: the most widespread application, used for early diagnosis, staging, treatment evaluation, and recurrence monitoring of tumors. Neuroscience: studying brain metabolism for the diagnosis of neurodegenerative diseases such as Alzheimer's disease. Cardiology: assessing myocardial viability (e.g., determining reversibility after myocardial infarction).

[0004] However, due to its radioactivity, radiation safety regulations must be followed during its transportation and use to protect operators, patients, and the environment. Therefore, a lead container with good protective performance for transporting FDG isotopes is needed to ensure adequate protection during transportation and before use, thus protecting operators. Utility Model Content

[0005] This invention provides a protective lead container for transporting FDG isotopes, which can ensure adequate protection during the transport of FDG isotopes and before use, protecting operators and solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a protective lead can for transporting FDG isotopes, comprising: a top cover, a lead can body, and locking connecting rings. The lead can body has an FDG isotope-containing cavity inside. The top cover and the lead can body are locked together by the locking connecting rings. Locking rings extending outwards a certain distance are provided on the lower edge of the top cover and the upper edge of the lead can body. The locking connecting rings are locked onto the two locking rings. A sealing ring is also placed between the top cover and the lead can body. This protective lead can for transporting FDG isotopes ensures adequate protection during transport and before use, protecting operators.

[0007] As an optional solution for the protective lead can for transporting FDG isotopes according to this utility model, the FDG isotope containing cavity includes a sealing part and a containing part. The sealing part is located above the containing part and is in the shape of an inverted frustum. The bottom of the upper cover is equipped with a sealing plug that matches the sealing part of the FDG isotope containing cavity. The shape and size of the sealing plug match the sealing part. This structure ensures that after the upper cover and the main body of the lead can are installed and connected, the container containing FDG isotopes is confined within the FDG isotope containing cavity, and it is not easy to shake during transportation.

[0008] As an optional solution for the protective lead can for transporting FDG isotopes according to this utility model, the locking connecting ring includes an open locking ring and a locking buckle connected to the opening of the locking ring. When the locking buckle is open, the diameter of the locking ring is relatively large, which makes it easier to operate. Furthermore, if the locking buckle is damaged, it is also easy to replace.

[0009] As an optional solution for the protective lead can for transporting FDG isotopes according to this utility model, the top of the cover is provided with a receiving groove, and a handle that can rotate 180° is connected to the inside of the receiving groove. After the handle is rotated to a certain angle, it can be completely placed in the receiving groove. The handle is designed to facilitate transportation. Setting the handle to be hidden facilitates the transportation and placement of multiple protective lead cans for transporting FDG isotopes.

[0010] As an optional solution for the protective lead can for transporting FDG isotopes according to this utility model, the bottom of the lead can body is provided with two fan-shaped placement platforms, and the sealing ring is made of silicone material.

[0011] This utility model has the following beneficial effects: The protective lead can for transporting FDG isotopes adopts a simple structural design, which realizes the protection of FDG isotopes during transportation and before use. It is convenient to transport, and multiple sealing guarantees are achieved. The structure is simple and easy to operate. Attached Figure Description

The top cover 1 and the locking ring 3 are also made of radiation-resistant metal material. An FDG isotope receiving cavity 21 is provided inside the lead can body 2. The FDG isotope receiving cavity 21 includes a sealing part and a receiving part. The sealing part is located above the receiving part and is shaped like an inverted frustum. A sealing plug 12 is provided at the bottom of the top cover 1 to match the sealing part of the FDG isotope receiving cavity 21. The shape and size of the sealing plug 12 match the sealing part. The container holding the FDG isotope is placed inside the FDG isotope receiving cavity 21. After assembly, the container holding the FDG isotope is confined inside the FDG isotope containing cavity 21. During transportation, it shakes. The locking ring 3 includes an open locking ring and a locking buckle connected to the opening of the locking ring. The upper cover 1 and the main lead container 2 are locked together by the locking ring 3. The lower edge of the upper cover 1 and the upper edge of the main lead container 2 are both provided with locking rings extending a certain distance outward. The locking ring 3 is locked onto the two locking rings. A sealing ring 4 is also placed between the upper cover 1 and the main lead container 2. The sealing ring 4 is made of silicone material. Multiple sealing protection is achieved through multiple sealing protection. The structure is simple and easy to operate.
