[0002] Radioactive drugs refer to radionuclide preparations or their labeled compounds used for clinical diagnosis or treatment. The difference between radioactive drugs and other drugs is that radioactive drugs contain radionuclides that can emit rays. Therefore, a transfer box with radiation protection is required during the transportation of radioactive drugs. The existing radiation protection transfer boxes have too simple structures and poor protection performance for medicine bottles, so improvement is needed.

[0003] Chinese Patent with the authorization announcement number CN217706824U discloses a radioactive drug transfer box. After installing the rotating shaft on the connecting rod in this transfer box, the rotation of the connecting rod will not cause direct friction to the box body, reducing the wear of the box body. And the bottom of the protection plate is lower than the bottom of the box body, serving the purpose of support to avoid the direct contact between the box body and the placement point, reducing the risk of being scratched or even punctured by hard objects.

[0004] However, this device still has deficiencies: this transfer box lacks the function of anti-collision protection for the medicine inside the box body and lacks the function of maintaining the temperature environment for storing medicine bottles. Summary of the Utility Model

[0026] As Figures 1 - 6As shown in the figure, a radioactive drug transfer box proposed by the present utility model includes a storage box 1, a cover plate 4, a pressure detection component, and a circulating temperature control component. A radiation shielding can 2 is arranged in the storage box 1, and a flexible protective pad A3 for placing medicine bottles is arranged in the radiation shielding can 2. A placement groove 301 for placing medicine bottles is arranged in the flexible protective pad A3, and the medicine bottle is in interference fit with the placement groove 301. The cover plate 4 is connected to the storage box 1. The cover plate 4 is connected to a lifting drive component 7, and the lifting drive component 7 is drivingly connected to a radiation shielding cover 8. The radiation shielding cover 8 is connected to a flexible protective pad B9. Both the radiation shielding cover 8 and the flexible protective pad B9 slide on the inner wall of the radiation shielding can 2. Among them, the lifting drive member 7 includes, but is not limited to, a scissor support and a hydraulic cylinder. An accommodation groove with an opening facing the radiation shielding can 2 is arranged on the radiation shielding cover 8. The top end of the scissor support is connected to the upper wall of the accommodation groove, and the bottom end of the scissor support is connected to the radiation shielding cover 8. The scissor support is drivingly connected to the scissor support. The storage box 1 is connected with a handle. Radiation warning signs are arranged on both the storage box 1 and the cover plate 4. The storage box 1 is rotatably connected to the cover plate 4, and a locking component 6 connecting the storage box 1 to the cover plate 4 is arranged on the storage box 1. The locking component 6 includes a buckle, a lock hook, and a lock. The lock hook is connected to the cover plate 4, and the buckle is connected to the storage box 1. The buckle cooperates with the lock hook, and the lock connects the buckle and the lock hook. The pressure detection component is connected to the radiation shielding cover 8 to control the lifting drive component 7 to stop operating after the pressure detection component detects that the medicine bottle is tightly wrapped. The pressure detection component includes a pressure sensor 10, a control component, and an energy storage component 19. The pressure sensor 10 is connected to the side of the radiation shielding cover 8 away from the cover plate 4 and is electrically connected to the control component. Both the pressure sensor 10 and the control component are electrically connected to the energy storage component 19. The energy storage component 19 is arranged in the storage box 1. The circulating temperature control component is in circulating communication with the inner cavity of the housing of the storage box 1, and maintains the environmental temperature for storing the medicine by circulating and introducing constant temperature water into the inner cavity. The circulating temperature control component includes a serpentine tube 16, a constant temperature water tank 17, and a circulation pump 18. Both the constant temperature water tank 17 and the circulation pump 18 are located in the storage box 1. The main body of the serpentine tube 16 is located in the inner cavity of the housing of the storage box 1 and is evenly distributed in a ring shape in the inner cavity. The two ends of the serpentine tube 16 are respectively communicated with the output end of the constant temperature water tank 17 and the circulation pump 18, and the input end of the circulation pump 18 is communicated with the inside of the constant temperature water tank 17. A temperature adjustment module is arranged in the constant temperature water tank. The temperature adjustment module is electrically connected to both the control component and the energy storage component 19. The circulation pump 18 is electrically connected to both the control component and the energy storage component 19.

[0027] In this embodiment, the lock is opened, and then the buckle is opened and the cover plate 4 is lifted. The staff places the radioactive agent into the placement groove 301 in the flexible protective pad A3. The medicine bottle has an interference fit with the inner wall of the placement groove 301. Through the surrounding protection of the flexible protective pad A, the shaking of the medicine bottle is avoided. Then the cover 4 is closed, and the hydraulic cylinder is started. The hydraulic cylinder drives the scissor-type bracket, and the scissor-type bracket presses down the radiation shielding cover 8 to move it towards the radiation shielding tank 2. After the radiation shielding cover 8 enters the radiation shielding tank 2, the flexible protective pad B9 contacts the flexible protective pad A3, and the two are mutually extruded until the flexible protective pad B9 abuts against the medicine bottle. At this time, the pressure sensor 10 detects that the pressure signal reaches a certain value, and the control component controls the hydraulic cylinder to stop working. At this time, the medicine bottle is protected by the enclosure of the flexible protective pad A3 and the flexible protective pad B9. When the storage box 1 falls or collides with other objects, the medicine bottle will not be damaged, thereby effectively avoiding the spillage of radioactive drugs. After the medicine bottle is clamped, the circulation pump 18 is started, and at the same time, the temperature adjustment module in the constant temperature water tank 17 is started. The circulation pump 18 circulates and extracts the constant temperature water in the constant temperature water tank 17 and injects it into the serpentine tube 16. The temperature is conducted to the inner wall of the storage box 1 through the serpentine tube 16 to keep the temperature in the inner chamber 101 of the storage box 1 constant and avoid the deterioration of the medicine due to temperature changes.

[0028] Embodiment 2

[0029] As Figure 4 and Figure 5 shown, a radioactive drug transfer box proposed by the present utility model, compared with Embodiment 1, a through hole 801 is provided on the radiation shielding cover 8. A radiation shielding tube 11 is provided in the through hole 801. An air flow channel 111 with a middle channel smaller than the two side openings is provided in the radiation shielding tube 11. Mounting plates 12 are provided on the inner sides of the two side openings of the radiation shielding tube 11. The two side mounting plates 12 are connected to the same sliding rod 13. The sliding rod 13 is slidably connected to the radiation shielding piston 14. The radiation shielding piston 14 is located in the middle channel and is slidably connected to its inner wall. Two springs 15 are sleeved on the sliding rod 13. The mutually remote ends of the two springs 15 are respectively abutted against the corresponding side mounting plates 12, and the mutually close ends of the two springs 15 are respectively abutted against the corresponding sides of the radiation shielding piston 14.

[0030] In this embodiment, after the radiation shielding cover 8 is snapped into the radiation shielding can 2, due to the close cooperation between the two, the air in the closed space of the can body will block the downward pressure of the radiation shielding cover 8. At this time, the air is compressed and the pressure increases. The compressed air pushes the radiation shielding piston 14 upward to make it slide upward to open the channel, and the air in the closed space of the can body surges upward to reduce the pressure difference inside and outside the can. When the radiation shielding cover 8 is pressed downward until the flexible protection pad B cooperates with the flexible protection pad A3 to clamp the medicine bottle, the radiation shielding cover 8 stops moving, and the gas in the can no longer pushes the radiation shielding piston 14. The radiation shielding piston 14 returns to the middle channel to prevent rays from overflowing through the channel. When the radiation shielding cover 8 is pulled upward, the radiation shielding piston 14 will move downward to open the air flow channel and will not hinder the upward movement of the radiation shielding cover 8. The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge of those skilled in the art to which the present invention pertains.
