Fig. 2 is a schematic structural view of the lead can of fig. 1, wherein the lead can contains a drug. Fig. 3 is a schematic cross-sectional view of the lead can of fig. 2, wherein the lead can accommodates a vial therein. Some embodiments of the present invention provide a radiopharmaceutical transport container, as shown in fig. 1-3, a radiopharmaceutical transport container 100 comprising: a medicine bottle 10, a lead can 20, a liquid absorbing sponge 30, a metal sealing can 40, a buffer protection layer 50 and a corrugated case 60.
The vial 10 is for containing a radiopharmaceutical, such as lutetium 177 Lu]Oxoargitide injection is suitable for treating unresectable or metastatic adult, progressive, highly differentiated (G1 and G2) and somatostatin receptor positive gastrointestinal and pancreatic neuroendocrine tumors (GEP-NETs). Lutetium [ lutetium ] 177 Lu]The clinical research on the risk of disease progression of the oxooctreotide injection is reduced by 79 percent compared with the traditional therapy.
177 Lu has obvious advantages in the field of tumor treatment due to its excellent radiation physical properties. It has the following advantages when being used for clinical diagnosis and treatment:
（1） 177 lu's beta ray has better energy deposition in small volume tumors, while it does not emit high-energy beta rays (76% beta decay (E) β (max) = 0.497 MeV)) to the surroundingsHealthy tissue causes high side effects;
(2) Low energy gamma rays (E) with beta ray emission γ =113 keV (6.6%), 208 keV (11%)) for SPECT imaging, which is extremely advantageous in the new generation of radiopharmaceutical development strategies currently oriented to "precision medicine", "personalized medicine", and "integrated therapy".
(3) In solution, lu exists in the +3 oxidation state and readily forms a coordination reaction with N, O, and thus can be linked to a wide variety of supports via bifunctional ligands. Meanwhile, lu has no other stable valence state, oxidation-reduction reaction is difficult to occur in the solution, the Lu can stably exist in +3 valence state in various chemical environments, the Lu labeled drug with high purity and stable chemical property can be obtained, and the Lu labeled drug can be effectively prevented from being metabolized in vivo in the research process 177 Lu is off-target, causing side effects to other tissues.
（4） 177 Lu has a suitable half-life (6.64 days) and facilitates cumbersome procedures for radiolabeling, purification, quality control and transportation.
177 Lu toxicity is grouped as toxic radionuclides. The half-life period is about 6.64 days, and due to the decay characteristics, the decayed beta rays have the characteristics of low energy, short range and no radioactive aerosol, and can meet the relevant requirements in the radioactive product safety transportation regulations on radiation protection only by making radioactive shielding.
The medicine bottle 10 is, for example, a penicillin bottle, which is, for example, an injection bottle made of borosilicate glass, and includes a medicine bottle body and a rubber plug matched with the medicine bottle body, wherein the rubber plug is buckled on the medicine bottle body to seal the radiopharmaceutical in the containing medicine bottle body.
The lead can 20 is used for accommodating the medicine bottle 10, and is used for isolating radiation of the radioactive medicine to avoid radiation leakage and pollution.
Imbibition sponge 30 is used for the parcel lead can 20 takes place the damage in order to absorb the liquid that leaks, even lead can and the medicine bottle of holding take place, the liquid radiopharmaceutical that flows out the lead can also can be adsorbed by the imbibition sponge, avoids liquid to leak, accords with air transport's requirement. The liquid absorption sponge 30 comprises a sponge body 31 and a sponge cover body 32, a first groove part 311 is arranged on the sponge body 31, a second groove part is arranged on the sponge cover body 32, when the sponge cover body 32 is buckled on the sponge body, the first groove part 311 and the second groove part are aligned and spliced, and the first groove part 311 and the second groove part are spliced to form a groove part for accommodating the lead can 20. The shape and dimensions of the groove are matched to the shape and dimensions of the lead can and substantially fits the lead can 20, for example the lead can 20 is cylindrical, also referred to as a cylindrical groove. For example, the size of the groove is equal to or slightly smaller than that of the lead can, so that the lead can 20 can be tightly wrapped by the liquid absorbing sponge 30 when being put into the groove of the liquid absorbing sponge 30, and the lead can 20 is prevented from shaking in the groove of the liquid absorbing sponge 30. Imbibition sponge 30 has still played the effect of firm lead can, and the elasticity performance of imbibition sponge 30 can also provide the cushioning effect in addition, prevents that lead can 20 from taking place the damage.
A metal sealed can 40 houses the lead can wrapped with the wicking sponge. The metal sealed can is made of an anti-corrosion material such as tin plate, and has good sealing and anti-corrosion characteristics and low price. Even if the lead can and the medicine bottle contained therein are damaged, the metal sealing can 40 can seal the liquid absorbing sponge absorbed with the radioactive liquid medicine to prevent contamination and leakage. In some embodiments, the shape and size of the interior space of the metal canister 40 matches the shape and size of the liquid-absorbing sponge 30. For example, as shown in fig. 1, the liquid-absorbing sponge 30 has a cylindrical shape, and the inner space of the metal can 40 also has a cylindrical shape. The size of the liquid absorption sponge 30 is, for example, equal to or slightly larger than the size of the inner space of the metal sealing can 40, so that when the liquid absorption sponge 30 wrapped with the lead can 20 is accommodated in the metal sealing can 40, the liquid absorption sponge 30 wrapped with the lead can 20 can be prevented from shaking in the metal sealing can 40, and the lead can and the medicine bottle therein can be stabilized.
The buffer protection layer 50 is configured to wrap the metal sealing can 40 and plays a role of buffering, and is made of, for example, a pearl foam material. The buffer protection layer 50 includes a protection layer body 51 and a protection layer cover 52, wherein the protection layer body 51 is provided with a third slot 511, for example, a non-through slot, the protection layer cover 52 is provided with a fourth slot 521, for example, a non-through slot, when the protection layer cover 52 is fastened on the protection layer body 51, the third slot 511 and the fourth slot 521 are aligned and spliced, and the two are spliced to form an accommodating slot for accommodating the metal sealing can 40. The receiving groove portion is matched in shape and size to the metal can 40, and substantially fittingly receives the metal can 40. For example, the metal can 40 is cylindrical, and the receiving groove is also called a cylindrical groove. For example, the size of the receiving groove is equal to or slightly smaller than that of the metal sealing can 40, so that the metal sealing can 40 can be tightly wrapped by the buffer protection layer 50 when being placed in the receiving groove of the buffer protection layer 50, and the metal sealing can 40 is prevented from shaking in the receiving groove of the buffer protection layer 50. The buffer protection layer 50 also plays a role in stabilizing the lead can, and the elastic performance of the buffer protection layer 50 can also provide a buffer effect to prevent the metal seal can 40 from being damaged.
The corrugated box 60 is configured to accommodate the metal sealed can 40 wrapped by the buffer protective layer 50. The corrugated case 60, which is used as the outermost package of the transport container 100, has the advantages of light weight, good cushioning property, low price, easy recycling, etc. In some embodiments, the shape and size of the interior space of the corrugated box 60 matches the shape and size of the cushioning protective layer 50. As shown in fig. 1, the buffer protection layer 50 is, for example, square, and the interior space of the corrugated box 60 is also square. The size of the buffer protection layer 50 is, for example, equal to or slightly larger than the size of the inner space of the corrugated case 60, so that when the buffer protection layer 50 wrapped with the metal seal can 40 is accommodated in the corrugated case 60, the buffer protection layer 50 wrapped with the metal seal can 40 can be prevented from shaking in the corrugated case 60, and the metal seal can 40 can be stabilized. In some embodiments, the corrugated box 60 has a square shape, for example, with a side length of 25cm, for example, to facilitate loading and carrying.
In some embodiments, the surface of the lead can 20 after receiving the vial 10 is heat sealed such that the outer surface of the lead can 20 is wrapped by a thermoplastic sealing film. The process of dispensing a radiopharmaceutical into a vial and housing the vial in a lead can is typically performed in a radiation-resistant environment, such as a radiation-resistant box, where the outer surface of the lead can inevitably contaminates the vial with a small amount of radioactive contaminants. In order to avoid causing harm to operators in the subsequent transportation operation process, a thermoplastic sealing film is formed on the outer surface of the lead can by adopting a thermal plastic packaging process to the lead can containing the medicine bottle taken out from the radioactive environment, and the lead can 20 is hermetically wrapped to isolate radioactive contamination on the outer surface of the lead can.
In addition, adopt the thermoplastic seal membrane including lead tank 20, can make the lead tank body and the lead tank lid of lead tank seal together for both are difficult for separating, guarantee the leakproofness of lead tank in the transportation.
In the embodiment, the corrugated paper box, the liquid absorbing sponge and the like are adopted to be matched with the lead can and the medicine bottle to form the disposable transport container, so that the cost is reduced under the condition of meeting the radioactivity protection requirement and the air transportation requirement. The transportation container has small volume, thereby being beneficial to the safety of loading; the weight is light, thus being beneficial to air transportation; the packaging mode is simple, and the stable and reliable packaging quality can be ensured; the disposable transport packaging material avoids the unsafe factor of reuse caused by the damage of the reusable transport package in the use process.
In some embodiments, the protective thickness of the lead can is determined in the following manner.

represents the absorption dose rate;
H=Ḋ·Q=2.54mSv/h，
wherein H represents an equivalent dose; the radiation weight factor Q =1.
If the dosage of the outer surface of the transport container is controlled to be 0.005mSv/h, the weakening multiple K =2.54/0.005=508, the radiation energy conservation is calculated according to 0.25MeV, the semivalence layer thickness of 0.88mm of 0.25MeV lead is calculated, lg2 (508) is 8.9887, and the thickness of the lead shielding layer is obtained by multiplying the semivalence layer thickness by 0.88 mm. At the same time, the lead can is then packaged in a secondary shipping package such that the shipping container is 10cm from the lead can, the dose rate at the surface of the bale will be well below 0.005mSv/h.
According to the above calculation, maximum 177 Lu activity is 250mCi, lead can thickness is designed to be 9mm, redundancy is increased, the lead can is placed in the center of the corrugated case, and the distance between the surface of the lead can and the surface of the transport container is 10cm (the distance between the surface of the transport container and the center of the radioactive source is 12.5 cm). The surface dose rate of the transport container was 0.16. Mu. Sv/h, calculated using Rad Pro calcelletor radiation protection calculation software. Is far lower than the regulation that H is more than 0.005mSv/H and less than or equal to 0.5mSv/H in the safety transportation regulation of radioactive products.
