[0003] The production of radioactive drugs is usually carried out in an isolation system with radiation protection functions. The radioactive nuclide is transferred to a reactor to carry out an isotope labeling reaction with a chemical precursor to prepare a radioactive labeled compound, which is the active ingredient of the radioactive drug. The radioactive drug is also carried out in an isolation system with radiation protection functions during the synthesis, sub-packaging and packaging processes. The radioactive drug is filled in a system composed of a vial, a rubber stopper and an aluminum cap or other reaction containers, and then conveyed by a conveying mechanism. The above process needs to be carried out in a clean environment and is preferably realized efficiently and stably by using automated equipment.

[0004] The existing radioactive material conveying mechanism has a relatively complex structure and occupies a large amount of internal space of the isolation chamber, which in turn leads to an increase in the volume of the isolation chamber and the protection cost. In addition, driving components such as motors are arranged inside the isolation chamber and are easily affected by the radiation of the drug, which is not conducive to ensuring the reliability of the driving components.

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0029] Figures 1 to 5 An embodiment of the radioactive material conveying device of the present utility model is shown. The radioactive material conveying device of this embodiment includes an isolation chamber 1, a conveying component 2 located inside the isolation chamber 1, and a driving component 3 located below the isolation chamber 1. A support structure 4 is provided inside the isolation chamber 1, a guide rail assembly 5 is provided on the support structure 4, the conveying component 2 is arranged on the guide rail assembly 5, and the driving component 3 is connected to the conveying component 2. Among them, the conveying component 2 can be, for example, a conveying platform, a conveying disk, a conveying frame, etc.; the support structure 4 can be, for example, a support platform and / or a support cross beam, etc.

[0030] For the radioactive material conveying device of this embodiment, the driving component 3 is connected to the conveying component 2, which can drive the conveying component 2 to move inside the isolation chamber 1 or between different partitions of the isolation chamber 1 to realize the conveying of materials. The guide rail assembly 5 provides a guiding function for the conveying component 2 to ensure the movement accuracy of the conveying component 2 and avoid deviation. The support structure 4 can provide support for the guide rail assembly 5, etc., to ensure stability; since the driving component 3 is arranged below the isolation chamber 1, it can reduce the occupation of the space of the isolation chamber 1 and the pollution risk to the isolation chamber 1, and at the same time, it can also reduce the radiation impact on the driving component 3. The structure is reasonable and effective.

[0031] Further, in this embodiment, a rotating shaft 7 penetrates through the lower side of the isolation chamber 1. The driving component 3 is connected to the lower end of the rotating shaft 7. A plurality of sets of connecting rod assemblies 6 are arranged between the upper end of the rotating shaft 7 and the conveying component 2. The connecting rod assembly 6 includes two first connecting rods 61 that are cross-hinged, and the first connecting rods 61 of the plurality of sets of connecting rod assemblies 6 are sequentially hinged. During operation, the driving component 3 can drive the rotating shaft 7 to rotate. The rotating shaft 7 drives the plurality of sets of connecting rod assemblies 6 that are sequentially hinged at the head and tail to extend or retract, thereby driving the conveying component 2 to reciprocate. The power transmission is reliable, and the structure is simple and effective. When the connecting rod assembly 6 is in the retracted and folded state, it occupies less space. By adjusting the number of the connecting rod assemblies 6, the purpose of adjusting the stroke of the conveying component 2 can be achieved, and it is convenient and flexible to use.

[0032] Specifically refer to Figures 2 to 4 , furthermore, in this embodiment, a limit seat 41 is provided on the support structure 4. Limit connecting rods 62 are provided on the hinge shafts of the two first connecting rods 61 of the plurality of sets of connecting rod assemblies 6 (or the middle parts of the two first connecting rods 61 and the limit connecting rods 62 are hinged). First rolling members 63 are provided at both ends of the limit connecting rods 62, and the two first rolling members 63 are arranged on both sides of the limit seat 41. Through the cooperation of the first rolling members 63 and the limit seat 41, it is ensured that the plurality of sets of connecting rod assemblies 6 and the conveying component 2 can only extend and retract forward and backward and will not move left and right, further improving the stability of the conveying process. Moreover, the first rolling members 63 and the limit seat 41 are in rolling friction, with small frictional resistance and small wear.

[0033] Furthermore, in this embodiment, second rolling members 64 are also provided at both ends of the limit connecting rods 62, and the second rolling members 64 are in contact with the upper surface of the limit seat 41. The limit seat 41 can provide support for the second rolling members 64 and the connecting rod assembly 6 to prevent downward deformation under the action of gravity, which is beneficial to ensuring that the connecting rod assembly 6 and the conveying component 2 only extend and retract forward and backward and will not deviate downward, which is beneficial to ensuring the repeat positioning accuracy. Moreover, the second rolling members 64 and the limit seat 41 are in rolling friction, with small frictional resistance and small wear.

[0034] As a preferred embodiment, the first rolling members 63 and the second rolling members 64 can be rollers or rolling bearings.

[0035] Further, in this embodiment, a driving connecting rod 71 is fixedly connected to the upper end of the rotating shaft 7 and a driven connecting rod 72 is rotatably connected. The driving connecting rod 71 is hinged to one first connecting rod 61 of the connecting rod assembly 6, and the driven connecting rod 72 is hinged to the other first connecting rod 61 of the connecting rod assembly 6. When the rotating shaft 7 rotates, it drives the driving connecting rod 71 to swing, thereby driving the connecting rod assembly 6 to unfold or fold up, and the driven connecting rod 72 rotates passively. The structure is simple and reliable.

One of the second linkages 21 is hinged to one first linkage 61 of the linkage assembly 6, and the other second linkage 21 is hinged to the other first linkage 61 of the linkage assembly 6. This connection method enables the expansion or contraction of the linkage assembly 6 to be converted into the reciprocating movement of the conveying member 2, with a simple and reliable structure.

[0037] As a preferred embodiment, the driving member 3 is a motor and is horizontally arranged. The output shaft of the motor is connected with a right-angle speed reducer 31, and the output shaft of the right-angle speed reducer 31 is connected to the lower end of the rotating shaft 7. The horizontal arrangement of the motor can reduce the overall height of the device, and the right-angle speed reducer 31 can achieve the reversing connection between the horizontally arranged motor and the vertically arranged rotating shaft 7, while achieving the purpose of speed reduction and torque increase, with a reasonable and effective structure.

[0038] Further, in this embodiment, the guide rail assembly 5 includes a first guide rail 51 provided on the support structure 4, a second guide rail 52 slidably engaged with the first guide rail 51, and a third guide rail 53 slidably engaged with the second guide rail 52. The conveying member 2 is provided on the third guide rail 53. The cooperation of the first guide rail 51, the second guide rail 52, and the third guide rail 53 occupies less space inside the isolation chamber 1 in the contracted state and can provide a sufficient long stroke in the expanded state, ensuring the flexible conveying of materials, with a simple and effective structure.
