Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical liquid production technology, and in particular to an integrated molybdenum-technetium generator. Background Technology

[0002] The molybdenum technetium generator is a device used to produce sterile, pyrogen-free 99mTc solutions. Due to its advantages of reusability, low cost, and ease of use, it is widely used in the medical field to provide better medical services to patients.

[0003] The generating column of a molybdenum-technetium generator is radioactive, so current molybdenum-technetium generators are equipped with an internal shield located inside the housing, with the generating column placed within the internal shield. Specifically, the internal shield has an inner cavity, and the generating column is located within the inner cavity. Because the eluent needs to be injected from outside the internal shield into its inner cavity to bring it into contact with the generating column, the generating column has a test tube-like structure. In practice, the eluent is injected into the generating column to bring it into contact with the generating column. Also, because the generated drug solution needs to be discharged from the inner cavity of the internal shield to the outside, the internal shield has an opening for a liquid conduit to pass through.

[0004] The opening obviously reduces the shielding effect of the internal shielding, so existing molybdenum technetium generators must be placed inside an external shielding during production. However, the external shielding is not originally provided by the molybdenum technetium generator and must be purchased by the user. This not only increases the operating cost of the molybdenum technetium generator, but also makes it inconvenient to use as the external shielding must be opened and closed every time the generator column is disassembled or assembled.

Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1:

[0050] Reference Figures 1-8 As shown, the integrated molybdenum technetium generator provided in this embodiment includes a housing, a lead shielding base 5, a generating column 6, a liquid inlet assembly 7, a liquid collection assembly 8, and a lead shielding block 9, wherein:

[0051] The lead shielding base 5 is installed in the outer shell. The lead shielding base 5 has a mounting hole 51 that penetrates one side of its surface. The generating column 6 (which is actually a test tube-like structure) is installed in the mounting hole 51. The liquid inlet assembly 7 and the liquid collection assembly 8 are both installed in the outer shell. The liquid inlet assembly 7 is used to inject the rinsing liquid into the mounting hole 51 and the generating column 6, so that the rinsing liquid sprays onto the generating column 6 in the mounting hole 51, thereby obtaining the desired drug solution. The liquid collection assembly 8 is used to extract the liquid from the generating column 6 so that the mounting hole 51 can be removed after the drug solution is generated. The lead shielding block 9 is installed in the outer shell and blocks the opening of the mounting hole 51.

[0052] In practical use, the rinsing solution is fed into the mounting hole 51 through the liquid inlet assembly 7, bringing it into contact with the generating column 6 to obtain the desired solution. The generated solution is then removed from the mounting hole 51 through the liquid collection assembly 8. The generating column 6 is placed in the mounting hole 51 of the lead shielding base 5, and the opening of the mounting hole 51 is sealed with a lead shielding block 9 to better provide radiation shielding. Therefore, the integrated molybdenum technetium generator provided by this utility model does not need to be placed in an external shielding body during use, resulting in a more compact structure. The generating column 6 can be disassembled and maintained simply by opening the outer shell, making it more convenient to use.

[0053] Optionally, the aforementioned outer casing includes a cylindrical body 1 and a cap 2. The top of the cylindrical body 1 forms a cylindrical opening. A lead shielding seat 5 is installed inside the cylindrical body 1. The aforementioned mounting hole 51 penetrates the top surface of the lead shielding seat 5. A mounting bracket is connected to the top of the lead shielding seat 5, and the mounting bracket is located in the cylindrical opening of the cylindrical body 1. The cap 2 is detachably connected to the mounting bracket via a connecting assembly, and the cap 2 seals the cylindrical opening of the cylindrical body 1 to facilitate the disassembly and assembly of the generating column 6. The liquid inlet assembly 7, the liquid collection assembly 8, and the lead shielding block 9 are all installed between the cap 2 and the mounting bracket. In this way, when the cap 2 is opened, the liquid inlet assembly 7, the liquid collection assembly 8, and the lead shielding block 9 can be easily disassembled, assembled, and maintained, resulting in a more compact structure. When the cap 2 is closed, the required liquid can be easily produced through the liquid inlet assembly 7 and the liquid collection assembly 8, while the lead shielding block 9 provides better radiation shielding. More preferably, a handle 4 is provided on the outer top wall of the cap 2.

[0054] Optionally, the mounting bracket includes a ring 10 and a plate 11. One end of the ring 10 is bonded to the top of the lead shielding seat 5 or bolted to the side wall at the opening of the cylinder 1. The mounting hole 51 of the lead shielding seat 5 is located inside the ring 10. The plate 11 is bonded to or bolted to the other end of the ring 10 and seals the other end of the ring 10. Alternatively, the plate 11 can be connected to the side wall at the opening of the cylinder 1 by a positioning pin. The plate 11, the ring 10, and the lead shielding seat 5 are connected to form a whole housed inside the cylinder 1. The cylinder cover 2 is detachably connected to the plate 11 by a connecting assembly, and the cylinder cover 2 is stacked on the plate 11. The outer diameter of the cylinder cover 2 is larger than that of the plate 11, and the plate 11 is located at the center of the bottom surface of the cylinder cover 2. An installation cavity is provided between the plate 11 and the cylinder cover 2. The lead shielding block 9 is installed in the installation cavity, and the lower part of the lead shielding block 9 penetrates through the plate 11 and the ring 10, and then overlaps on the top surface of the lead shielding seat 5 and seals the opening of the installation hole 51 on the lead shielding seat 5.

[0055] With the aforementioned connecting components, it is convenient for the user to disassemble and assemble the cylinder cover 2. After opening the cylinder cover 2, the aforementioned mounting bracket and lead shielding block 9 are exposed first. After removing the lead shielding block 9, the mounting hole 51 of the aforementioned lead shielding seat 5 is exposed, thereby facilitating the disassembly and assembly of the generating column 6. In this embodiment, the generating column 6 is a gel-type molybdenum technetium generating column 6 or a fission-type molybdenum technetium generating column 6. Because it is easy to disassemble and assemble, it can be quickly replaced according to the usage situation.

[0056] The aforementioned mounting cavity serves as the chamber for installing the lead shielding block 9. This chamber is located between the cylinder cover 2 and the mounting bracket. Specifically, a first groove 21 is provided at the center of the bottom surface of the cylinder cover 2, and a second groove 111 is provided at the center of the top surface of the plate 11. The second groove 111 corresponds to and is joined with the first groove 21 to form the aforementioned mounting cavity. A through hole 112 penetrating the bottom surface of the plate 11 is also provided at the bottom of the second groove 111. The upper part of the lead shielding block 9 is installed in the aforementioned mounting cavity, while the lower part of the lead shielding block 9 passes through the aforementioned through hole 112 and the inner hole of the aforementioned ring 10.

[0057] When the cap 2 is connected to the plate 11, the lead shielding block 9 can be firmly clamped in the above-mentioned mounting cavity, making the structure more compact and reasonable, and easier to assemble and disassemble.

[0058] Optionally, the connecting assembly includes a latch 12, which has a column and a locking block at one end of the column. A connecting hole 113 is provided on the plate 11, the column is connected in the connecting hole 113, the locking block is located above the plate 11, and a latch hole 22 is provided on the bottom surface of the cylinder cover 2. The locking block is engaged in the latch hole 22, thereby connecting the cylinder cover 2 to the plate 11. Specifically, the number of latches 12 installed on the plate 11 is multiple (e.g., 3), and the multiple latches 12 are evenly distributed around the through hole 112 on the plate 11. Correspondingly, the number of latch holes 22 on the cylinder cover 2 is also multiple, and the multiple latch holes 22 correspond one-to-one with the multiple latches 12, thereby connecting the cylinder cover 2 more securely and tightly to the cylinder opening.

[0059] The aforementioned buckle hole 22 includes an insertion port 221 and an arc-shaped buckle groove 222 located on the side of the insertion port 221. The arc-shaped buckle groove 222 penetrates the bottom surface of the aforementioned cylindrical cover 2, and the longitudinal section of the arc-shaped buckle groove 222 is "T"-shaped. In use, the locking block is inserted into the buckle hole 22 through the insertion port 221, and then the cylindrical cover 2 is rotated, so that the locking block enters the aforementioned arc-shaped buckle groove 222, thereby making the locking block fastened in the buckle hole 22. When it is necessary to remove the cylindrical cover 2, the cylindrical cover 2 is reversed, so that the locking block is moved out of the buckle hole 22 and into the aforementioned insertion port 221. The operation is simple and convenient.

[0060] To prevent the cylinder cover 2 from automatically reversing, the connecting assembly in this embodiment also includes a positioning buckle 13. The positioning buckle 13 has a positioning post and a handle, with the handle located at one end of the positioning post. The cylinder cover 2 has a first positioning hole 23, and the plate 11 has a second positioning hole 115. The positioning post is inserted into the first positioning hole 23 and the second positioning hole 115 to position the cylinder cover 2 in place on the plate 11. The handle is located above the cylinder cover 2. It is easy to understand that the positioning buckle 13 is actually a positioning and locking component. Only when the cylinder cover 2 is rotated to the correct position (i.e., the locking block enters the arc-shaped buckle groove 222) can the positioning buckle 13 be simultaneously inserted into the first positioning hole 23 and the second positioning hole 115. After insertion, the cylinder cover 2 is restricted, preventing it from rotating. The handle facilitates the installation and removal of the positioning buckle 13.

[0061] If the cap 2 needs to be removed, first pull out the positioning buckle 13, and then reverse the cap 2. Since the cap 2 needs to be rotated to be installed and removed from the plate 11, in order to rotate the cap 2 more flexibly, in this embodiment, a ball bearing 3 is rotatably installed on the bottom surface of the cap 2. The ball bearing 3 protrudes from the bottom surface of the cap 2 and overlaps the top surface of the plate 11, thereby avoiding direct contact between the bottom surface of the cap 2 and the top surface of the plate 11. This reduces the friction when the cap 2 rotates, making it easier to rotate the cap 2.

[0062] Optionally, both the liquid inlet assembly 7 and the liquid collection assembly 8 include a needle 14, a guide tube 15, and a bottle body 16, wherein:

[0063] The needle 14 has a mounting part 141 and a needle part 142. The mounting part 141 is connected to the plate 11. The cap 2 has a through hole 24, and the needle part 142 is inserted into the through hole 24. The guide tube 15 is connected to the bottom end of the mounting part 141 and communicates with the needle part 142. A tube-laying groove 52 is provided on the top surface of the lead shielding base 5. The tube-laying groove 52 is located to the side of the opening of the mounting hole 51 and communicates with the mounting hole 51. The guide tube 15 is laid in the tube-laying groove 52 and extends into the mounting hole 51 (actually, it extends into the generating column 6). The bottle mouth of the bottle body 16 is sealed by a rubber sealing member (e.g., a rubber plate). The bottle body 16 is inserted upside down into the through hole 24, and the needle part 142 pierces the rubber sealing member and then communicates with the interior of the bottle body 16. Optionally, a solenoid valve can be installed on the guide tube 15 to control its on / off state.

[0064] Of course, the bottle 16 of the liquid inlet assembly 7 can be a conventional bottle containing rinsing liquid. Under the action of gravity, the rinsing liquid can automatically flow down into the guide tube 15 of the liquid inlet assembly 7 and drip into the mounting hole 51. Alternatively, the bottle 16 of the liquid inlet assembly 7 can be made soft. When in use, the user can squeeze the bottle 16 of the liquid inlet assembly 7 to squeeze the rinsing liquid, causing the rinsing liquid to spray into the mounting hole 51 and generate the spray column 6.

[0065] The bottle body 16 of the liquid collection assembly 8 is a negative pressure bottle, and the guide tube 15 of the liquid collection assembly 8 also extends to the lower part of the generating column 6 in the mounting hole 51, using the negative pressure of the negative pressure bottle to draw out the liquid generated in the generating column 6.

[0066] Alternatively, the aforementioned liquid inlet assembly 7 may also include a liquid delivery pump, which, along with the guide pipe 15, delivers the rinsing liquid into the generating column 6 within the mounting hole 51. The aforementioned liquid collection assembly 8 may also include a water pump, which, along with the corresponding guide pipe 15, extracts the liquid generated within the mounting hole 51.

[0067] In order to ensure that the mounting part 141 is stably connected to the plate 11, in this embodiment, a notch 116 is provided in the plate 11. The notch 116 is located on the side of the second groove 111 and communicates with the second groove 111. Moreover, the notch 116 penetrates the upper and lower surfaces of the plate 11. A snap 1411 is provided on the outer wall of the mounting part 141, and a snap strip 114 is provided on the side wall of the notch 116. The mounting part 141 is inserted into the notch 116, and the snap strip 114 is engaged with the snap 1411.

[0068] To protect the needle 14 when the bottle 16 is not installed in the through hole 24, a protective cap is also attached to the cap 2 in this embodiment. When no bottle is installed in the through hole 24, the protective cap seals the through hole 24. When it is necessary to install the bottle into the through hole 24, the protective cap is opened. The protective cap can be attached to the top opening of the through hole 24 by snap-fit, or it can be glued to the top surface of the cap 2 and seal the through hole 24.
