[0002] Nuclear medicine is an emerging discipline that uses nuclear technology to diagnose, treat and study diseases. It is the product of the combination of modern science and technology such as nuclear technology, electronic technology, computer technology, chemistry and biology with medicine. Nuclear medicine can be divided into two categories, namely clinical nuclear medicine and basic nuclear medicine or experimental nuclear medicine. In the nuclear medicine department of a hospital, when medical staff perform radionuclide treatment operations, some radioactive medical waste with radiation is inevitably generated. These radioactive wastes must be stored in special containers.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0028] like Figures 1 to 7As shown, the automated treatment and storage system for nuclear medicine waste in this embodiment comprises a base plate 1, and radiation-proof shells 2 are symmetrically and slidably installed at the front and rear parts of the base plate 1. The radiation-proof shells 2 are made of lead material, which is an excellent radiation-proof material. It can effectively prevent radiation and has a protective effect on general radiation, and can even reduce radiation to zero. Lead can absorb radiation generated by nuclear reactions and reduce the harm of radiation to the human body. A delivery port 4 is arranged on the upper end of one radiation-proof shell 2, and the delivery port 4 is used to deliver waste generated by nuclear medicine. An installation groove 5 is arranged at one end of another radiation-proof shell 2 in front of the delivery port 4, and a sliding installation is arranged inside the installation groove 5. There is a baffle 6, which can slide out from the inside of the installation groove 5, so that the baffle 6 can block the delivery port 4 to prevent the radiation generated by the nuclear medical waste from leaking through the delivery port 4. The material of the baffle 6 is the same as that of the radiation protection shell 2, and both can isolate and protect the radiation generated by the nuclear medical waste. A driving component is installed at the lower end of the baffle 6, and the driving component is used to move the driving baffle 6 to facilitate the baffle 6 to be in a suitable position. A sensing plate 8 is installed at the upper end of the radiation protection shell 2 on one side of the delivery port 4. The sensing plate 8 is used to intelligently control the driving component. By shielding the top of the sensing plate 8, the sensing plate 8 can control the driving component Start to drive the baffle 6 to open the delivery port 4. The induction plate 8 works based on the principle of capacitive sensors. The induction plate 8 works based on the change of capacitance. When an object approaches, the capacitance value of the sensor will change, thereby realizing contactless opening of the baffle 6 to avoid contact between the staff and the device. A placement box 9 is installed on the upper end of the bottom plate 1. The placement box 9 can store nuclear medical waste. A delivery tube 10 is installed on the upper end of the placement box 9. The delivery tube 10 is located directly below the delivery port 4. The nuclear medical waste dropped through the delivery port 4 can enter the placement box 9 through the delivery tube 10. The inside of the placement box 9 A support plate 11 is installed, and an extrusion assembly is installed above the support plate 11. A rotating limit plate 13 is rotatably connected inside the placement box 9 on one side of the support plate 11. The rotating limit plate 13 is initially in a vertical upward state. The rotating limit plate 13 cooperates with the extrusion assembly to compress the nuclear medical waste, so as to reduce the overall volume of the nuclear medical waste. A collecting box 14 is placed below the rotating limit plate 13. The collecting box 14 is used to place the compressed nuclear medical waste. A liquid storage box 15 is placed on one side of the collecting box 14. The liquid storage box 15 is used to store liquid in the nuclear medical waste, thereby realizing the solid-liquid separation and storage of the nuclear medical waste.

[0029] Specifically, sliding grooves 16 are arranged at both ends of the bottom plate 1, and a sliding plate 17 is installed at one end inside the radiation protection shell 2. The sliding plate 17 is slidably installed inside the sliding groove 16. The two radiation protection shells 2 are assembled by sliding combination, which can isolate and protect the placement box 9. When the radiation protection shell 2 slides, the sliding plate 17 slides inside the sliding groove 16, which guides the movement of the radiation protection shell 2.

[0030] Furthermore, a fixing plate 18 is installed in the middle of the lower end of the base plate 1, and connecting plates 19 are respectively installed at the lower ends of the two radiation protection shells 2 in front and rear of the fixing plate 18, and electric telescopic rods 20 are respectively installed between the front and rear end surfaces of the fixing plate 18 and the two connecting plates 19. By controlling the two electric telescopic rods 20 to extend, the two electric telescopic rods 20 drive the two radiation protection shells 2 to move toward each other through the connecting plate 19, so that the two ends of the placement box 9 are exposed to the outside, which is convenient for the post-processing of the solid nuclear medical waste inside the collection box 14 and the nuclear medical liquid inside the liquid storage box 15, and convenient for use.

[0031] Furthermore, the driving assembly includes a driving motor 701, a driving gear 702 and a fixed rack 703. The fixed rack 703 is installed at the lower end of the baffle 6, and the driving motor 701 is installed at the top of the radiation protection shell 2 on one side of the fixed rack 703. The driving gear 702 is installed at the output end of the driving motor 701, and the driving gear 702 and the fixed rack 703 are meshed. When the baffle 6 needs to be moved to open the delivery port 4, the driving motor 701 is controlled to rotate, and the driving motor 701 drives the driving gear 702 to rotate. The driving gear 702 rolls on the fixed rack 703 to realize the movement of the fixed rack 703, and the baffle 6 is driven to move to the inside of the mounting groove 5 through the fixed rack 703 to realize the opening of the delivery port 4. The driving motor 701 is connected to a forward and reverse circuit, and the driving motor 701 can drive the driving gear 702 to rotate forward and reverse.

[0032] Furthermore, the extrusion assembly includes an electric telescopic rod 1201, a push plate 1202 and a guide block 1203. The electric telescopic rod 1201 is installed at one end of the placement box 9 above the support plate 11, and the push plate 1202 is installed at the output end of the electric telescopic rod 1201. A guide block 1203 is installed between the front and rear ends of the placement box 9 on one side of the push plate 1202. An inclined surface 21 is arranged above one end of the guide block 1203. One end of the guide block 1203 contacts one end of the push plate 1202. The nuclear medical waste dropped through the delivery tube 10 drops to the push plate 1202 through the inclined surface 21 on the guide block 1203. Above the support plate 11 on one side, the electric telescopic rod 1201 is extended to drive the push plate 1202 to push the nuclear medical waste on the support plate 11. The push plate 1202 and the rotating limit plate 13 squeeze the nuclear medical waste to effectively reduce the volume of the nuclear medical waste. After squeezing the nuclear medical waste, the rotating limit plate 13 rotates to a vertical downward state. As the electric telescopic rod 1201 continues to push, the compressed nuclear medical waste can be pushed off the support plate 11 and fall into the collection box 14. Then the rotating limit plate 13 rotates back to an upward vertical state to complete the automatic processing of the nuclear medical waste.

[0033] Furthermore, a driving motor 22 is installed at the front end of the placement box 9 in front of the rotating limit plate 13. The output end of the driving motor 22 is located inside the placement box 9 and a rotating shaft 23 is installed. The rotating limit plate 13 is rotatably installed on the surface of the rotating shaft 23. When the driving motor 22 rotates, the rotating limit plate 13 is driven to rotate by the rotating shaft 23, so that the rotating limit plate 13 can be converted from a vertical upward state or a vertical downward state. The driving motor 22 is connected to a forward and reverse circuit. The driving motor 22 can drive the rotating limit plate 13 to rotate forward and reverse. The driving motor 22 has an automatic locking function. Therefore, when the driving motor 22 is not driven, the rotating limit plate 13 will not rotate accidentally, and the rotation angle of the rotating limit plate 13 is 180° each time.

[0034] Furthermore, a plurality of seepage holes 24 are arranged through the upper end of the support plate 11 on one side of the push plate 1202. When the nuclear medical waste is compressed, the liquid in the nuclear medical waste falls through the seepage holes 24 to achieve the separation of solid and liquid nuclear medical waste. A guide plate 25 is installed at the lower end of the support plate 11 below the seepage holes 24. One end of the guide plate 25 extends to the inside of the liquid storage box 15. The setting of the guide plate 25 is convenient for guiding the liquid nuclear medical waste and discharging the liquid nuclear medical waste into the liquid storage box 15. Notches 26 are arranged at both ends of the placement box 9 below the support plate 11. The setting of the notch 26 makes it convenient to take the collection box 14 and the liquid storage box 15 out of the placement box 9 through the notch 26, so as to facilitate the later treatment of the nuclear medical waste inside the liquid storage box 15 and the collection box 14.

[0035] Furthermore, four metal support columns 27 are installed in a rectangular array at the lower end of the bottom plate 1, and a base 28 is placed under the bottom plate 1. A placement hole 29 is arranged on the upper end of the base 28 below the metal support column 27, and an electromagnet 30 is installed at the bottom end of each placement hole 29. By placing the metal support column 27 into the placement hole 29 and energizing the electromagnet 30, the electromagnet 30 attracts the metal support column 27 to fix the metal support column 27. A power module 31 is installed inside the base 28. The power module 31 is used to power each electrical appliance, and the power module 31 can power the electrical components on the radiation protection shell 2 and the placement box 9 through cables. A number of moving wheels 32 are installed at the lower end of the base 28. The setting of the moving wheels 32 makes it easy to push the base 28, so that the use position of the placement box 9 on the base 28 can be changed according to actual use requirements, which is convenient for use.

[0036] The method of using this embodiment is as follows: first, the metal support column 27 under the bottom plate 1 is placed into the placement hole 29 on the base 28, and the electromagnet 30 is energized, so that the electromagnet 30 can attract the metal support column 27 to realize the combination of the bottom plate 1 and the base 28, and then the base 28 can be moved to a suitable position by pushing. When placing nuclear medical waste, the staff only needs to cover the top of the induction plate 8, and the induction plate 8 controls the driving motor 1 701 to rotate, and the driving motor 1 701 drives the driving gear 702 to rotate. The driving gear 702 rotates, and the fixed rack 703 drives the baffle 6 to move to the inside of the installation slot 5, so that the delivery port 4 is opened. The nuclear medical waste passes through the delivery port 4 and the delivery tube 10 into the placement box 9, and falls on the support plate 11 on one side of the push plate 1202. After the specified time is reached, the driving motor 1 701 drives the baffle 6 to move in the opposite direction, so that the baffle 6 blocks the delivery port 4 again, and then the electric telescopic rod 2 1201 drives the push plate 1202 to move, and the push plate 1202 The vertically upward rotating limit plate 13 can squeeze the nuclear medical waste, effectively reducing the volume of the nuclear medical waste. At the same time, the liquid in the nuclear medical waste falls onto the guide plate 25 through the seepage hole 24, and enters the liquid storage box 15 through the guide plate 25. Then, the driving motor 22 drives the rotating limit plate 13 to rotate through the rotating shaft 23, so that the rotating limit plate 13 is in a vertical downward state. With the continuous movement of the push plate 1202, the compressed nuclear medical waste can be pushed into the collection box 14, completing a nuclear medical waste collection. The push plate 1202 returns to its original position, and the rotating limit plate 13 is in a vertical upward state again. With the compression of nuclear medical waste for many times, when the liquid storage box 15 and the collection box 14 need to be cleaned, the electric telescopic rod 20 is controlled to extend, and the electric telescopic rod 20 drives the two radiation protection shells 2 to move toward each other through the connecting plate 19, so that the two ends of the placement box 9 are exposed to the outside, and the collection box 14 and the liquid storage box 15 can be taken out through the notch 26, and the nuclear medical waste inside the collection box 14 and the liquid storage box 15 can be processed.
