Description

Technical Field

[0001] The utility model relates to the technical field of radiopharmaceuticals, in particular to a lead can used for transfer, transportation and protection of an automatic drug administration system for radiopharmaceuticals. Background Art

[0002] With the rapid development of nuclear medicine technology, radiopharmaceuticals are increasingly used in the diagnosis and treatment of diseases. These drugs contain radioactive isotopes that can target specific types of cells or tissues, thereby achieving accurate diagnosis and efficient treatment. However, due to their inherent radioactive properties, radiopharmaceuticals require radiation protection during handling, storage, and transportation to ensure the safety of workers and the public. In the past, the injection of radiopharmaceuticals mostly used the traditional manual injection method, with nurses manually packaging and injecting them, which complicated the workflow. With the largest number of examinations, the radiation dose received by nurses was large, especially to the hands, which could easily exceed 100mSv / year. In addition, the packaging of drugs was not accurate, affecting the quality of the examination report, and the probability of radiation contamination accidents was high.

[0003] The automatic radiopharmaceutical dosing system is used for fully automatic and precise packaging and injection of radiopharmaceuticals, which greatly reduces the radiation dose of operators; improves the accuracy of patient dosing, reduces drug consumption, and reduces medical costs and the probability of radioactive accidents.

[0004] However, during the use of the automatic drug delivery system, the radiation protection of the radioactive drugs during transportation is relatively weak, which can easily lead to excessive radiation doses for workers and the public. To this end, we propose a lead canister for the transfer and transportation protection of the automatic drug delivery system. Utility Model Content

Each inner tank body has a separate sealing cover, which can effectively isolate radioactive sources of different types or dose levels, and at the same time enhance the safety and sealing of the overall structure; a sealing door 105 is hingedly provided on the lower part of the outer surface of the outer tank body 1, which is used to seal the outer tank body 1 and the inner tank body 2 as a whole, adopting an inner and outer double tank structure, which greatly improves the radiation protection performance during the transfer and transportation of radioactive drugs and ensures the personal safety of workers and the public.

[0023] The preferred technical solution is that a card plate 106 corresponding to the sealing door 105 is rotatably provided on the upper portion of the outer surface of the outer tank body 1, and a card block is fixedly provided on the side surface of the sealing door 105. A card slot corresponding to the card block is opened on the card plate 106. After closing the sealing door 105, the card plate 106 is rotated so that it is stuck on the card block through the card slot, and the sealing door 105 can be closed to ensure that it will not be easily opened during the moving and transportation process, and the sealing door 105 can be opened conveniently and quickly when the inner tank body 2 needs to be taken out.

[0024] The sealing door 105 is hingedly arranged at the lower part of the outer tank body 1. After opening the sealing door 105, its free end can be placed on the ground so that the whole door is tilted to form a slope that facilitates the inner tank body 2 to enter the interior of the outer tank body 1, making it easier for the inner tank body 2 to be pushed into the outer tank body 1, making it more convenient to use.

[0025] In a preferred technical solution, an outer tank handle 103 is fixedly provided on the side of the outer tank body 1 away from the sealing door 105, making it easy for workers to pull the outer tank body 1 for transportation or connect it to an external drive vehicle. An inner tank handle 204 is provided on the side surface of the outermost inner tank body 2, which allows the inner tank body 2 to be easily pushed into or pulled out of the outer tank body 1.

[0026] According to a preferred technical solution, an annular sealing groove 207 is provided on the upper surface of the inner tank body 2, and a sealing gasket 208 matching the sealing groove 207 is fixedly provided on the inner surface of the sealing cover 205. When the sealing cover 205 is covered on the inner tank body 2, the sealing gasket 208 also enters the sealing groove 207 and is squeezed, which can greatly improve the sealing performance of the inner tank body 2 and reduce the possibility of radiation leakage.

[0027] A further preferred technical solution is that a fixing column 209 is fixedly provided on the upper surface of the inner tank body 2 away from the sealing cover 205, and a bar-shaped rotating block 210 is rotatably provided on the top of the fixing column 209. The inner surface of the sealing cover 205 is provided with a bar groove 211 corresponding to the rotating block 210, and the outer surface of the sealing cover 205 is provided with a circular groove 212 connected to the bar groove 211. When the sealing cover 205 is covered on the inner tank body 2, the rotating block 210 and the fixing column 209 are both inserted into the bar groove 211, and then the rotating block 210 enters the circular groove 212. At this time, the rotating block 210 is rotated to a state where it does not overlap with the bar groove 211, so that the sealing cover 205 can be fixed, thereby further improving the sealing of the inner tank body 2 and ensuring the overall stability of the lead can during transfer and transportation.

[0028] An optional technical solution is that a frame-shaped cooling rack 3 is placed in the inner tank body 2. The interior of the cooling rack 3 is hollow and filled with a cooling medium such as an ethylene glycol aqueous solution or water. A liquid injection port 301 is opened on the upper surface of the cooling rack 3, and a sealing plug is provided at the liquid injection port 301. When transporting radioactive drugs that need to be kept at low or high temperatures, the cooling rack 3 can be frozen or heated to a certain temperature in advance and then placed in the inner tank body 2. The drugs are then placed inside the cooling rack 3, and finally the inner tank body 2 is sealed by the sealing cover 205. This can ensure that the ambient temperature of the radioactive drugs is at an appropriate temperature during transfer and transportation, thereby ensuring that their quality is not affected.

[0029] A further optional technical solution is that the inner surface of the sealing cover 205 is provided with a sealing block 206 corresponding to the cooling rack 3. After the cooling rack 3 is placed in the inner tank body 2, there is a certain distance between its top surface and the top surface of the inner tank body 2. After the sealing cover 205 is closed, the sealing block 206 can fill the distance to further improve the sealing of the inner tank body 2, reduce heat exchange during transfer and transportation, and extend the insulation time of the medicine.

[0030] As an optional technical solution, a foot brake 102 is further provided on the outer wheel frame of the outer tank body 1 near the outer tank body handle 103, so that the outer tank body 1 can be parked conveniently.
