When the syringe needle is inserted into the sub-bottle, the telescopic drive stops and the up-down drive starts, causing the upper limit assembly to move downward, which in turn drives the syringe piston handle downward, thereby injecting the radioactive liquid in the syringe into the sub-bottle. The telescopic drive then causes the upper and lower limit assemblies to move upward simultaneously, removing the syringe needle from the sub-bottle. The next sub-bottle can then be injected with radioactive liquid. This achieves automated sub-bottle dispensing of radioactive liquid without human intervention, effectively preventing radioactive contamination of the environment or human body.

[0044] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] The following combination Figures 1 to 7 The present invention describes the automatic radioactive liquid dispensing device and method.

[0046] As attached Figure 1 As shown, the automatic radioactive liquid packaging device includes a shell 1, a telescopic driving member, an upper and lower driving member 2, a telescopic sleeve 3, a connecting block 4, an upper limit assembly 5, a lower limit assembly 6, a bearing member 7 and a rotating driving member.

[0047] Specifically, the telescopic drive member is fixedly mounted within the housing 1. One end of the vertical drive member 2 is mounted on the telescopic drive member. The telescopic sleeve 3 is mounted on the upper surface of the housing 1. The other end of the vertical drive member 2 is connected to the inner wall of the telescopic sleeve 3. The telescopic shaft of the vertical drive member 2 passes through the telescopic sleeve 3 and is connected to one end of the connecting block 4. The upper limit assembly 5 is mounted on the other end of the connecting block 4. The lower limit assembly 6 is mounted on the telescopic sleeve 3 and is located below the upper limit assembly 5. The bearing 7 is mounted on the upper surface of the housing 1. The rotational drive member is mounted within the housing 1 and is connected to the bearing 7.

[0048] During use, the upper half of the shell 1 is installed in the shielding layer, and the upper surface of the shell 1 is located in the chamber, and then the radioactive liquid is packaged in the chamber. The barrel of the syringe is clamped with the lower limit assembly 6, and the barrel of the syringe is limited and fixed by the lower limit assembly 6, so that the barrel of the syringe remains stationary during the process of radioactive liquid packaging. The piston handle of the syringe is clamped with the upper limit assembly 5, and the piston handle of the syringe is limited and fixed by the upper limit assembly 5, so that the piston handle of the syringe moves with the up and down movement of the connecting block 4. Then, multiple sub-bottles for loading radioactive liquids are placed on the carrier 7, and the carrier 7 is driven to rotate by the rotating drive member, so that the sub-bottles are rotated to the bottom of the syringe.

[0049] The telescopic drive then drives the upper and lower drive members 2 to move up and down, causing the telescopic sleeve 3 and the lower stop assembly 6 mounted thereon to move up and down with it. The movement of the upper and lower drive members 2 also drives the connecting block 4 and the upper stop assembly 5 mounted thereon to move synchronously. The upper and lower drive members 2 drive the telescopic shaft up and down, which in turn drives the connecting block 4 up and down, and the upper stop assembly 5 also moves up and down with it. When dispensing radioactive liquid, the telescopic drive first causes the upper and lower stop assemblies 5 and 6 to move downward simultaneously, causing the syringe barrel and piston handle to move downward simultaneously. Once the syringe needle is inserted into the dispensing bottle, the telescopic drive stops, and the upper and lower drive members 2 begin operating, causing the upper stop assembly 5 to move downward, which in turn causes the syringe piston handle to move downward, thereby injecting the radioactive liquid in the syringe into the dispensing bottle. The telescopic drive then again causes the upper and lower stop assemblies 5 and 6 to move upward simultaneously, releasing the syringe needle from the dispensing bottle. The next dispensing bottle can then be injected with radioactive liquid. This enables automated packaging of radioactive liquids without human intervention, effectively preventing radioactive contamination of the environment or human body. Furthermore, electrical components such as the telescopic drive, vertical drive 2, and rotational drive are all mounted within the housing 1, while mechanical components are directly exposed to the chamber. This prevents reflective materials from damaging electronic components and increases the device's service life.

[0050] When the radioactive liquid in one of the sub-bottles needs to be transferred to another sub-bottle, the needle of the syringe is first inserted into one of the sub-bottles, and then the upper limit assembly 5 is driven upward by the upper and lower driving members 2, so that the piston handle of the syringe moves upward, and then the radioactive liquid in one of the sub-bottles is extracted into the syringe, and then the supporting member 7 is rotated to rotate the other sub-bottle under the syringe, and then the needle of the syringe is inserted into the other sub-bottle, and then the upper limit assembly 5 is moved downward to drive the syringe piston handle downward, and then the radioactive liquid in the syringe is injected into the other sub-bottle, thereby realizing the automatic transfer of the radioactive liquid.

[0051] In an optional embodiment of the present invention, the upper and lower driving members 2, the telescopic driving member and the rotating driving member are, for example, cylinder driving members. However, it should be understood that the upper and lower driving members 2, the telescopic driving member and the rotating driving member can also be any other suitable driving members.

[0052] Wherein, the sub-bottle used in the present invention is for example a negative pressure bottle, so that the syringe can smoothly extract liquid from the sub-bottle or inject liquid into the sub-bottle. However, it should be understood that the sub-bottle can also be any other suitable container, for example a container with a vent.

[0053] In an optional embodiment of the present invention, the bottom of the sub-filling bottle is conical, so that the solution in the sub-filling bottle can be completely extracted by a syringe.

[0054] In an optional embodiment of the present invention, the needle of the syringe is, for example, an elastic needle, thereby making the syringe.

[0055] Further, as attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the upper limit assembly 5 includes an upper limit seat 51, an upper pressing block 52, and an upper deflector 53. One end of the upper limit seat 51 is connected to the connecting block 4, and the other end of the upper limit seat 51 is provided with an upper clamping groove 54. The upper limit seat 51 is also provided with a first through hole 55 that matches the upper clamping block 52. One end of the upper clamping block 52 is clamped into the first through hole 55, and the upper deflector 53 is connected to the other end of the upper clamping block 52. During use, the piston handle of the syringe is clamped into the upper clamping groove 54, and then an external force is applied to the upper deflector 53, causing the upper deflector 53 to rotate from one side to the other side, thereby driving the upper clamping block 52 to rotate. After the upper clamping block 52 rotates, it abuts against the piston handle of the syringe clamped in the clamping groove. The upper clamping block 52 presses and fixes the syringe piston handle in the clamping groove, thereby achieving the limit fixation of the syringe piston handle.

[0056] Among them, as attached Figure 2 and attached Figure 3 As shown, in an optional embodiment of the present invention, the upper pressing block 52 is shaped like a vertically cut cylinder, and the vertically cut cross section of the upper pressing block 52 is a rectangle. However, it should be understood that the upper pressing block 52 can also be any other suitable shape.

[0057] Among them, as attached Figure 2 As shown, the upper limit seat 51 is further provided with a rotation limit block 56, one end of which is located on one side of the upper pressing block 52, and the other end of which is located on the other side of the upper pressing block 52. The upper lever 53 is located above the rotation limit block 56. During use, the upper lever 53 is initially located at one end of the rotation limit block 56. At this time, the cut surface of the upper pressing block 52 faces downward, and there is a certain gap between the upper pressing block 52 and the piston stem of the syringe engaged in the upper clamping groove 54. The upper lever 53 is then rotated from one side of the rotation limit block 56 to the other side of the rotation limit block 56. As the upper pressing block 52 rotates, the upper pressing block 52 abuts against the piston stem of the syringe, thereby clamping and fixing the syringe piston stem. The rotation limit block 56 limits the rotation range of the upper lever 53, preventing the upper lever 53 from rotating arbitrarily and making it difficult to clamp and fix the syringe piston stem stably.

[0058] Among them, as attached Figure 2As shown, in an optional embodiment of the present invention, the rotation limit block 56 is a U-shaped limit block. However, it should be understood that the shape of the rotation limit block 56 can also be a limit block of any other suitable shape.

[0059] Among them, as attached Figure 2 and attached Figure 3 As shown, a groove 57 is provided at one end of the upper pressing block 52, and a second through-hole is further provided on the upper limit seat 51. A stopper 58 matching the groove 57 is provided in the second through-hole. The stopper 58 is located below one end of the upper pressing block 52 and engages with the groove 57. During use, one end of the upper pressing block 52 is inserted into the first through-hole 55, and then the stopper 58 is passed through the second through-hole and engages with the groove 57 of the upper pressing block 52. The stopper 58 thus limits the upper pressing block 52 and prevents it from falling out of the first through-hole 55.

[0060] Further, as attached Figure 1 , Attachment Figure 4 and attached Figure 5 As shown, the lower limit assembly 6 includes a lower limit seat 61, the lower half of which is provided with a lower clamping groove 62. A lower pressing block 63 is rotatably connected to the middle position of the lower limit seat 61. The lower pressing block 63 is located above the lower clamping groove 62 and is provided with a notch 64. During use, the notch 64 is first positioned above the lower clamping groove 62, and then the barrel of the syringe is clamped to the lower clamping groove 62. Then, an external force is applied by the lower clamping block 63, causing the lower clamping block 63 to rotate, causing the notch 64 to rotate as well, and the lower clamping block 63 to abut against the syringe barrel, thereby achieving a limited fixation of the syringe barrel.

[0061] Among them, as attached Figure 4 As shown, the lower pressing block 63 includes a threaded post 631 and a lower lever 632. The lower limit seat 61 is provided with a threaded hole that matches the threaded post 631. One end of the lower lever 632 is connected to the threaded post 631. During use, an external force is applied to the lower lever 632 to rotate the threaded post 631. When the barrel of the syringe is locked in the lower locking groove 62, the threaded post 631 is rotated, causing the threaded post 631 to rotate and move downward, thereby allowing the threaded post 631 to compress and fix the syringe barrel.

[0062] Among them, as attached Figure 4 As shown, a limiting post 611 is provided on the upper surface of the lower limiting seat 61. When in use, when an external force is applied to the lower lever 632 to rotate the lower pressing block 63, the limiting post 611 can limit the lower lever 632, preventing the lower lever 632 from continuing to rotate and causing the lower pressing block 63 to separate from the lower limiting seat 61.

[0063] Among them, as attached Figure 1and attached Figure 5 As shown, the lower limit seat 61 is installed on the telescopic sleeve 3, and a plurality of first connection holes 612 are provided on the connection surface between the lower limit seat 61 and the telescopic sleeve 3. Second connection holes corresponding to the first connection holes 612 are provided on the connection surface between the telescopic sleeve 3 and the lower limit seat 61. During use, a fastener is inserted through the second connection hole and then into the first connection hole 612, thereby fixing the lower limit seat 61 and the telescopic sleeve 3 together. Since the fastener and the connection hole are both located at the connection between the lower limit seat 61 and the telescopic sleeve 3, neither the fastener nor the connection hole is exposed to the external environment, making the surface of the sub-packaging device smoother, effectively preventing radioactive substances from remaining on the connection holes or fasteners and being difficult to wipe and clean, and facilitating wiping of the sub-packaging device to avoid residual radioactive substances.

[0064] Among them, as attached Figure 1 and attached Figure 5 As shown, the lower limit seat 61 includes an upper plate 613 and a lower plate 614. The upper plate 613 is provided with a plurality of third connection holes, and the lower plate 614 is provided with fourth connection holes 615 corresponding to the third connection holes. A fastener is inserted through the fourth connection hole 615 and then into the third connection hole to securely connect the upper plate 613 and the lower plate 614 together. During use, the fastener is inserted upward from the fourth connection hole 615 of the lower plate 614 into the third connection hole to securely connect the upper plate 613 and the lower plate 614. The opening of the fourth connection hole 615 is downward, preventing radioactive material from being retained in the connection hole or the fastener.

[0065] In an optional embodiment of the present invention, the fastener is, for example, a screw. However, it should be understood that the fastener may also be any other suitable structural member.

[0066] Further, as attached Figure 1 and attached Figure 6 As shown, the automatic radioactive liquid dispensing device further includes a needle guide assembly 8, which is fixedly mounted on the upper surface of the housing 1 and is located below the lower limit assembly 6. During use, the syringe is mounted on the upper limit assembly 5 and the lower limit assembly 6. During the radioactive liquid dispensing process, the syringe needs to be continuously moved up and down so that the syringe needle can be continuously inserted into or removed from the dispensing bottle. The needle guide assembly 8 is used to guide the up and down movement of the needle and limit the needle. The syringe needle passes through the needle guide assembly 8 and is inserted into or removed from the dispensing bottle, preventing the syringe needle from being inserted crooked during the up and down movement, resulting in dispensing failure or bending of the syringe needle.

[0067] Among them, as attached Figure 6As shown, the needle guide assembly 8 includes a needle guide frame 81, one end of which is fixedly mounted on the upper surface of the housing 1, and the other end of the needle guide frame 81 is provided with a needle guide hole 82, which is located below the lower limit assembly 6. During use, the syringe needle passes through the needle guide hole 82 and is inserted into the sub-filling bottle to inject the radioactive liquid into the sub-filling bottle. The syringe then moves upward, causing the syringe needle to detach from the sub-filling bottle, but at this time the syringe needle is still in the needle guide hole 82. The syringe needle then moves downward along the needle guide hole 82 to operate on another sub-filling bottle. After all sub-filling bottles are operated or the radioactive liquid in the syringe is injected, the syringe moves upward, driving the syringe needle to completely detach from the needle guide hole 82, thereby achieving a guiding and limiting effect on the syringe needle and ensuring that the radioactive liquid dispensing operation can proceed smoothly.

[0068] Further, as attached Figure 1 As shown, the automatic radioactive liquid dispensing device further includes a tungsten sleeve 9, which is installed at the connection between the telescopic sleeve 3 and the housing 1. During use, the telescopic sleeve 3 is generally fixed to the housing 1 using fasteners such as screws. The tungsten sleeve 9 is provided at the connection between the telescopic sleeve 3 and the housing 1. The tungsten sleeve 9 can isolate the fasteners such as screws from the chamber, preventing them from being irradiated by radioactive substances and extending the service life of the device.

[0069] Further, as attached Figure 1 As shown, the housing 1 includes a housing 11 and a cover plate 12. The housing 11 is provided with a cavity, and the cover plate 12 is detachably connected to the upper end of the housing 11. During use, the telescopic drive member, the upper and lower drive member 2, the telescopic sleeve 3, the bearing member 7, and the rotation drive member are all mounted on the cover plate 12. By removing the cover plate 12 from the housing 11, the cover plate 12 and various components thereon can be removed one by one, facilitating quick replacement.

[0070] Among them, as attached Figure 1 As shown, the cover plate 12 is provided with a plurality of connecting members 13, and the upper end of the housing 11 is provided with a fifth connecting hole that matches the connecting members 13. During use, the cover plate 12 is fixedly connected to the housing 11 by inserting the connecting members 13 into the fifth connecting hole, and the cover plate 12 is separated from the housing 11 by pulling the connecting members 13 out of the fifth connecting hole, thereby achieving the purpose of quick replacement.

[0071] In an optional embodiment of the present invention, the connecting member 13 is, for example, a hand screw. However, it should be understood that the connecting member 13 may also be any other suitable connecting structural member.

[0072] On the other hand, as attached Figure 7 As shown, the present invention also provides a method for automatically dispensing radioactive liquid, comprising:

[0073] S1. Number the sub-bottles in ascending order of volume, add up the volumes of all sub-bottles to get the total volume, and then compare the total volume with the maximum capacity of the syringe;

[0074] S2. When the total volume is less than the maximum capacity, the syringe draws out radioactive liquid that is consistent with the total volume and then injects it into each sub-bottle in turn;

[0075] S3. When the total volume is greater than the maximum capacity, determine the volume of the largest sub-bottle, add the volume of the first sub-bottle, the second sub-bottle, the third sub-bottle, and so on. If the total volume exceeds the maximum capacity, draw a standard volume of radioactive solution and inject it into the first to (n-1)th sub-bottles and the largest sub-bottle, where the standard volume is the total volume minus the volume of the nth sub-bottle.

[0076] S4. Renumber the remaining sub-bottles in ascending order of volume, and then repeat step S3 until the injection of the radioactive solution in all sub-bottles is completed.

[0077] When in use, first determine whether the syringe can inject the radioactive solution into all the sub-bottles at one time. If it can, then directly inject the radioactive solution into all the sub-bottles, and the radioactive solution sub-packaging process is completed.

[0078] If not, first add the volume of the largest sub-bottle to the volume of the first sub-bottle, and determine whether the added volume exceeds the maximum capacity. If it exceeds, the syringe first draws out a volume of radioactive solution consistent with the volume of the largest sub-bottle, and injects the radioactive liquid into the largest sub-bottle.

[0079] If the sum of the volume of the largest sub-bottle and the volume of the first sub-bottle does not exceed the maximum capacity, the volume of the second sub-bottle is added, and a determination is made as to whether the sum exceeds the maximum capacity. If so, a volume of radioactive solution equal to the sum of the volume of the largest sub-bottle and the volume of the first sub-bottle is drawn into the syringe, and the radioactive solution is injected into the largest sub-bottle and the first sub-bottle. If not, the volume of the third sub-bottle is added, and the sum is compared with the maximum capacity, and so on, until the sum exceeds the maximum capacity.

[0080] When the combined volume of the largest sub-bottle and the first sub-bottle exceeds the maximum capacity, the radioactive liquid is first injected into the largest sub-bottle. The second-largest sub-bottle is then found among the remaining sub-bottles. The volume of the second-largest sub-bottle is then compared with the volume of the first sub-bottle to determine whether the combined volume exceeds the maximum capacity. If so, the syringe extracts radioactive liquid equal to the volume of the second-largest sub-bottle and injects it into the second-largest sub-bottle. If not, the combined volume of the second-largest sub-bottle and the first sub-bottle is added to the volume of the second sub-bottle, and then a determination is made as to whether the combined volume exceeds the maximum capacity. This process continues until all sub-bottles have been injected with radioactive liquid. This allows for planning the optimal injection solution before injecting the radioactive solution into the sub-bottles, enabling rapid radioactive solution dispensing.

[0081] For example, if a group of six vials are dispensed, and the equivalent volumes of the six vials are 1.8mL, 3mL, 5mL, 6mL, 7.3mL, and 4mL, respectively, the 1.8mL and 7.3mL vials will be injected with radioactive solution first, followed by the 3mL and 6mL vials, and finally the 4mL and 5mL vials. This allows for rapid dispensing of radioactive solutions.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
