Description

Technical Field

[0001] The utility model relates to the technical field of installing an ion exchange column on a radioactive drug synthesizer, in particular to an ion exchange column clamping device. Background Art

[0002] Radiopharmaceutical synthesizer is an instrument for synthesizing radionuclides and plays a vital role in the production process of preparing radionuclides.

[0003] Radiopharmaceutical synthesizers are usually composed of synthesizers, controllers, PCs, synthesis control software, temperature control systems, radioactive detectors, flow plates, various pipelines and valves. In the actual process of synthesizing nuclides, the ion exchange column needs to be fixed on the outer wall of the synthesizer by installation, usually fixed on the top wall, which is conducive to the ion exchange column for drug separation and purification, and improves the purity and efficiency of the drug. In the prior art, the ion exchange column is fixed by placing the ion exchange column on a clamping block, specifically, the clamping block is provided with a flat groove, the width of the flat groove is equal to the diameter of the ion exchange column, and it is found in the actual clamping process that the ion exchange column needs to be manually forced into the flat groove, and it also needs to be forcibly removed when removed, which requires the hand to exert a lot of strength, causing inconvenience in disassembly and assembly; when clamping multiple ion exchange columns for a long time, it is more laborious and causes damage to the hands.

[0004] The existing clamping block has the problem of causing damage to the hands due to the inability to assemble or disassemble it. Utility Model Content

[0005] In order to solve the technical problem that the clamping block cannot be disassembled and assembled and causes injuries to the hands, the utility model provides an ion exchange column clamping device, which can easily add the ion exchange column to the clamping block through a connecting seat clamping part, a clamping part and a slot.

[0006] In order to achieve the above object, the utility model is implemented through the following technical solutions:

[0007] An ion exchange column clamping device, comprising:

[0008] The connecting seat is fixed on the outer wall of the radiopharmaceutical synthesizer.

[0009] The clamping block is arranged on the connecting seat and is fixedly connected to the side wall of the connecting seat.

[0010] The clamping part is arranged on the clamping block and connected with the clamping block as a whole. A U-shaped groove is provided on the clamping part, and the column body of the ion exchange column is located in the U-shaped groove.

[0011] The slot is arranged on the clamping block, extends from the clamping block to the clamping portion, is plugged with the lower portion of the ion exchange column, and is used to clamp the ion exchange column together with the clamping portion to limit the ion exchange column in the clamping block.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] During installation, the column body of the ion exchange column can be clamped by the U-shaped groove, and the slot clamps the lower part of the ion exchange column, and then the ion exchange column is clamped in the clamp block, making it easier to clamp in. During disassembly, the ion exchange column can be taken out of the U-shaped groove and the slot. Avoid forcibly inserting and disassembling the ion exchange column, save time and effort, facilitate disassembly, and avoid injury to the hands.

[0014] More preferably, the clamping portion comprises:

[0015] The first clamping body is located at the upper part of the clamping part and is integrally connected with the clamping block, and the inner wall of the first clamping body is in contact with the side wall of the ion exchange column.

[0016] The second clamping body is located at the lower part of the clamping part, is integrally connected with the clamping block, and is parallel to the first clamping body. The slot is located between the first clamping body and the second clamping body.

[0017] The U-shaped groove is formed in the first clamping body and the second clamping body, and passes through the first clamping body to the second clamping body.

[0018] By adopting the above technical solution, the lower part of the ion exchange column is inserted into the slot, so that the lower part is clamped between the first clamp and the second clamp, and the column body is confined in the first clamp by the U-shaped groove, so that the ion exchange column can be easily clamped.

[0019] More preferably, the clamping block is further provided with:

[0020] The deformation groove is a through groove, which is set in the clamping block, spans across the two sides of the U-shaped groove, and passes through from the top surface of the first clamping body to the bottom surface of the second clamping body.

[0021] The contraction portion is fixed in the bending portion of the U-shaped groove and connected to the inner wall of the U-shaped groove, and is used for changing the width of the deformation groove by contraction.

[0022] By adopting the above technical solution, when it is necessary to clamp an ion exchange column with a larger diameter, the opening of the first clamp and the opening of the second clamp need to be separated to both sides, and the contraction part is stretched by the first clamp and the second clamp. At this time, the width of the deformation groove becomes smaller and the opening of the U-shaped groove becomes larger. The body of the ion exchange column can be easily placed in the U-shaped groove, and the lower part of the ion exchange column enters the slot accordingly, thereby achieving the purpose of easily clamping an ion exchange column with a larger diameter.

[0023] More preferably, the contraction portion comprises:

[0024] The contraction groove is provided at the bending part of the U-shaped groove, and is respectively located on the first clamp body and the second clamp body, and its edge is connected to the inner wall of the U-shaped groove, and is used to change the width of the U-shaped groove by extension and contraction.

[0025] The shrinkage belt is arranged on the shrinkage groove, plugged with the shrinkage belt, and the side wall contacts the outer wall of the ion exchange column, and is used to change the width of the deformation groove by stretching and shrinking.

[0026] By adopting the above technical solution, after the shrinkage band is plugged into the shrinkage groove, the shrinkage groove changes within the width range of the deformation groove, so that the size of the U-shaped groove changes within a smaller range, thereby clamping an ion exchange column slightly larger than the conventional size. When the shrinkage band is removed, the shrinkage groove changes within a larger size range with the change of the first clamp and the second clamp, thereby clamping an ion exchange column of a larger size.

[0027] Further optimization is that a connecting strip is provided on the shrinkage groove, which is located in the deformation groove and has an edge connected to the deformation groove, so as to reduce or increase the width of the deformation groove through the deformation generated by the shrinkage groove.

[0028] By adopting the above technical solution, the U-shaped groove can be slightly changed by the connecting strip to clamp the ion exchange column slightly larger than the conventional size, and the shrinkage groove can be prevented from breaking at the deformation groove, thus having the characteristic of a firm structure.

[0029] Further optimization is that the cross section of the connecting strip is triangular.

[0030] The above technical solution is adopted to match the structure of the shrinkage groove, so that the shrinkage groove is well connected to the deformation groove.

[0031] Further optimization is that the shrink belt is respectively provided with:

[0032] A plurality of racks are evenly distributed on the contraction groove and plugged into the contraction groove.

[0033] The connecting belt is located between every two adjacent racks, and its edge portion is connected to the edge portion of the racks. The ion exchange column is located in the connecting belt.

[0034] By adopting the above technical solution, the contraction belt formed by the rack and the connecting belt forms a good matching connection with the contraction groove, ensuring that the contraction groove can expand and contract within the width range of the deformation groove.

[0035] Further optimization is that the materials of the connecting belt and the rack are both elastic materials.

[0036] The above technical solution is adopted to ensure that different degrees of expansion and contraction deformation occur.

[0037] Further optimization is that the slot and the deformation groove form a cross shape.

[0038] The above technical solution ensures that the lower part of the ion exchange column is smoothly inserted into the slot, while also ensuring that the U-shaped slot is within the range of the deformation slot.

[0039] Further optimization is as follows: the thickness of the first clamp is greater than the thickness of the second clamp.

[0040] By adopting the above technical solution, the purpose of clamping the lower part of the ion exchange column together with the second clamp, the first clamp and the slot is achieved while the first clamp clamps the body of the ion exchange column. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The following is combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 The utility model is further introduced in detail.

[0051] An ion exchange column clamping device, such as Figure 1 As shown, including:

[0052] The connecting seat 1 is fixed on the outer wall of the radiopharmaceutical synthesizer.

[0053] The clamping block 2 is arranged on the connecting seat 1 and is fixedly connected to the side wall of the connecting seat 1 .

[0054] The clamping portion 21 is disposed on the clamping block 2 and is integrally connected to the clamping block 2 . A U-shaped groove 213 is formed on the clamping portion 21 . The body of the ion exchange column 3 is located in the U-shaped groove 213 .

[0055] The slot 22 is provided on the clamping block 2 , extends from the clamping block 2 to the clamping portion 21 , and is plugged into the lower portion of the ion exchange column 3 , so as to clamp the ion exchange column 3 together with the clamping portion 21 to limit the ion exchange column 3 in the clamping block 2 .

[0056] During installation, the body of the ion exchange column 3 can be clamped by the U-shaped groove 213, and the slot 22 can clamp the lower part of the ion exchange column 3, so that the ion exchange column 3 can be clamped in the clamping block 2 more easily. During disassembly, the ion exchange column 3 can be taken out from the U-shaped groove 213 and the slot 22. It is avoided that the ion exchange column 3 is forced to be inserted and disassembled, which saves time and effort, facilitates disassembly, and avoids injury to the hands.

[0057] Specifically, Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the clamping portion 21 includes:

[0058] The first clamping body 211 is located at the upper part of the clamping portion 21 and is integrally connected to the clamping block 2 , and the inner wall thereof is in contact with the side wall of the ion exchange column 3 .

[0059] The second clamping body 212 is located at the lower part of the clamping portion 21 , is integrally connected to the clamping block 2 , and is parallel to the first clamping body 211 . The slot 22 is located between the first clamping body 211 and the second clamping body 212 .

[0060] The U-shaped groove 213 is formed in the first clamping body 211 and the second clamping body 212 , and passes through the first clamping body 211 to the second clamping body 212 .

[0061] The lower part of the ion exchange column 3 is inserted into the slot 22 so that the lower part is clamped between the first clamp 211 and the second clamp 212 . The column body is confined in the first clamp 211 by the U-shaped groove 213 , so that the ion exchange column 3 can be easily clamped.

[0062] Specifically, Figure 1 , Figure 2 as well as Figure 3 As shown, in this embodiment, the clamp block 2 is also provided with:

[0063] The deformation groove 24 is a through groove, which is formed in the clamping block 2 , spanning across two sides of the U-shaped groove 213 , and passing through from the top surface of the first clamping body 211 to the bottom surface of the second clamping body 212 .

[0064] The contraction portion 23 is fixedly disposed in the bending portion of the U-shaped groove 213 and connected to the inner wall of the U-shaped groove 213 , and is used to change the width of the deformation groove 24 by contraction.

[0065] When it is necessary to clamp an ion exchange column 3 with a larger diameter, the opening of the first clamp 211 and the opening of the second clamp 212 need to be separated to both sides, and the contraction portion 23 is stretched by the first clamp 211 and the second clamp 212. At this time, the width of the deformation groove 24 becomes smaller, and the opening of the U-shaped groove 213 becomes larger, so that the body of the ion exchange column 3 can be easily placed in the U-shaped groove 213, and the lower part of the ion exchange column 3 enters the slot 22 accordingly, so as to achieve the purpose of easily clamping the ion exchange column 3 with a larger diameter.

[0066] Specifically, Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, in this embodiment, the contraction portion 23 includes:

[0067] The contraction groove 231 is provided at the bending part of the U-shaped groove 213 and is respectively located on the first clamp body 211 and the second clamp body 212 . Its edge is connected to the inner wall of the U-shaped groove 213 and is used to change the width of the U-shaped groove 213 by extension and contraction.

[0068] The shrinkage band 232 is disposed on the shrinkage groove 231 , and is plugged into the shrinkage band 232 , with the side wall in contact with the outer wall of the ion exchange column 3 , so as to change the width of the deformation groove 24 by stretching and shrinking.

[0069] After the shrink band 232 is plugged into the shrink groove 231, the shrink groove 231 changes within the width of the deformation groove 24, so that the size of the U-shaped groove 213 changes within a smaller range, thereby clamping an ion exchange column 3 slightly larger than the conventional size. When the shrink band 232 is removed, the shrink groove 231 changes within a larger size range along with the changes of the first clamp 211 and the second clamp 212, thereby clamping an ion exchange column 3 of a larger size.

[0070] Specifically, Figure 4 and Figure 6 As shown, in this embodiment, a connecting strip 2311 is provided on the contraction groove 231, which is located in the deformation groove 24, and its edge is connected to the deformation groove 24, and is used to reduce or increase the width of the deformation groove 24 through the deformation generated by itself. The connecting strip 2311 not only makes the U-shaped groove 213 slightly changed to clamp the ion exchange column 3 slightly larger than the conventional size, but also makes the contraction groove 231 not easy to break at the deformation groove 24, and has the characteristics of a strong structure. The material of the connecting strip 2311 is selected from either rubber or silicone, so that the connecting strip 2311 has a certain flexibility and can shrink, deform or recover in the deformation groove 24.

[0071] Specifically, Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, in this embodiment, the cross section of the connecting strip 2311 is triangular, which matches the structure of the shrinkage groove 231 and connects the shrinkage groove 231 well at the deformation groove 24 .

[0072] Specifically, Figure 5 , Figure 6 as well as Figure 7 As shown, in this embodiment, the shrink belt 232 is respectively provided with:

[0073] A plurality of racks 2321 are evenly distributed on the contraction groove 231 and plugged into the contraction groove 231 .

[0074] The connecting belt 2322 is located between every two adjacent racks 2321 , and its edge is connected to the edge of the rack 2321 . The ion exchange column 3 is located in the connecting belt.

[0075] The contraction belt 232 formed by the rack 2321 and the connection belt 2322 forms a good matching connection with the contraction groove 231 , ensuring that the contraction groove 231 can expand and contract within the width range of the deformation groove 24 .

[0076] Specifically, Figure 5 , Figure 6 as well as Figure 7 As shown, in this embodiment, the materials of the connecting belt 2322 and the rack 2321 are both elastic materials, preferably rubber materials, to ensure different degrees of expansion and contraction deformation.

[0077] Specifically, Figure 8 As shown, in this embodiment, the slot 22 and the deformation slot 24 form a cross shape, which ensures that the lower part of the ion exchange column 3 is smoothly inserted into the slot 22, while also ensuring that the U-shaped slot 213 is within the range of the deformation slot 24.

[0078] Specifically, Figure 1 As shown, in this embodiment, the thickness of the first clamp 211 is greater than the thickness of the second clamp 212, so that the first clamp 211 clamps the body of the ion exchange column 3 while the second clamp 212, the first clamp 211 and the slot 22 clamp the lower part of the ion exchange column 3 together.

[0079] Please combine Figure 1-Figure 8 The process of clamping ion exchange columns 3 of different diameters in this embodiment is described as follows:

[0080] Hold the body of the ion exchange column 3 and align it with the U-shaped groove 213. Insert the lower part of the ion exchange column 3 into the slot 22, and the body enters the clamping groove. If the body diameter of the ion exchange column 3 is the same as the width of the U-shaped groove 213, the outer wall of the body contacts the inner wall of the U-shaped groove 213, so that the ion exchange column 3 is clamped in the clamping block 2, and the ion exchange column 3 of standard diameter size is clamped and fixed. Figure 3 As shown, the deformation groove 24 divides the clamping part 21 into a first clamping body 211 and a second clamping body 212. When the ion exchange column 3 with a diameter larger than the width of the U-shaped groove 213 is clamped, the first clamping body 211 and the second clamping body 212 are opened by hand to narrow the deformation groove 24, and at the same time, the shrinkage groove 231 is opened to both sides to increase the width of the U-shaped groove 213, and then the column body is placed in the U-shaped groove 213, and the lower part of the ion exchange column 3 is inserted into the slot 22, and the first clamping body 211 and the second clamping body 212 are released, and the column body is clamped in the clamping block 2, so that the ion exchange column 3 with a larger diameter can be clamped.

[0081] In summary, the above installation process is simple and easy to operate, and the ion exchange column 3 is easy to install and fix, which has the characteristics of saving time and effort and avoiding injuries to the hands. The U-shaped groove 213 can clamp ion exchange columns 3 of various diameters and sizes, and has strong practicality and a wide range of applications.

[0082] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
