Abstract
Description
Technical Field
[0001] This utility model relates to the field of purification device technology, specifically a purification device for the production of biological antibodies. Background Technology
[0002] Antibodies are protective proteins produced by the body in response to antigen stimulation. They are large, Y-shaped proteins secreted by plasma cells and used by the immune system to identify and neutralize foreign substances such as bacteria and viruses. They are found only in the blood and other bodily fluids of vertebrates, and on the cell membrane surface of their B cells. Antibodies recognize a unique characteristic of a specific foreign substance; this foreign target is called an antigen. During the production of biological antibodies, impurities are filtered out to purify them.
[0003] Chinese utility model CN218665851U discloses a novel purification device for protein antibodies, which designs a structure to restrict the purification tubes. The principle is that an adjustment component is set on a disc. When purification tubes of different specifications are placed on the disc, a matching insert ring is inserted into the mounting base. The insert ring is engaged by a locking block and a locking slot. After the purification tube is inserted, the insert ring can restrict the shaking of the purification tube.
[0004] However, existing devices are cumbersome to use, the slots are small and difficult to operate, and a suitable connecting ring is required, making them inconvenient to use. Therefore, a purification tube clamping mechanism was designed to address the above-mentioned problems and facilitate operation. Summary of the Invention

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0031] Antibodies are protective proteins produced by the body in response to antigen stimulation. They are large, Y-shaped proteins secreted by plasma cells and used by the immune system to identify and neutralize foreign substances such as bacteria and viruses. They are found only in the blood and other bodily fluids of vertebrates, and on the cell membrane surface of their B cells. Antibodies recognize a unique characteristic of a specific foreign substance; this foreign target is called an antigen. During the production of biological antibodies, impurities are filtered out to purify them.
[0032] In related technologies, an adjustment component is set on the disc. When purification tubes of different specifications are placed on the disc, a matching insert ring is inserted into the mounting base. The insert ring engages with a locking block and a locking slot, and then the purification tube is inserted. The insert ring can limit the shaking of the purification tube. However, the existing device is relatively cumbersome to use. The locking slot is small and difficult to operate. In addition, it is necessary to find a suitable insert ring for connection, which is not convenient to use.
[0033] To address some of the problems in related technologies, this application provides a purification device for biological antibody production. When it is necessary to clamp the purification tube 14, the purification tube 14 is first inserted into the horizontal plate 13. Then, by rotating the threaded rod 25, and because the threaded rod 25 is threadedly connected to the horizontal plate 13 and the ring 24 is restricted from rotating due to being fitted onto the outer wall of the tube 21, the horizontal plate 13 moves downwards while the threaded rod 25 rotates, pushing the ring 24 downwards. This causes the ring 24 to squeeze the clamping block 23, which rotates inside the tank 22 and clamps the purification tube 14 on one side, maintaining stability.
[0034] This application is described below with reference to the accompanying drawings and specific embodiments:
[0035] Combination Figures 1-4 This application provides a purification device for biological antibody production, comprising: a housing 11 with a filter box 12 disposed inside; a horizontal plate 13 disposed inside the housing 11; a purification tube 14 inserted into a through groove of the horizontal plate 13, with its top end connected to a flexible tube at the bottom of the filter box 12; a clamping assembly 2 disposed on the horizontal plate 13, the clamping assembly 2 comprising: a tube body 21 sleeved on the outer wall of the purification tube 14, with its top end connected to the horizontal plate 13; a groove 22 formed on the outer wall of the tube body 21; a clamping block 23 disposed inside the groove 22, with its top end rotatably connected to the inner wall of the groove 22; a ring body 24 sleeved on the outer wall of the tube body 21; and a threaded rod 25, the bottom end of which penetrates the horizontal plate 13 and is rotatably connected to the ring body 24 and threadedly connected to the horizontal plate 13.
[0036] Specifically, the purpose of filter box 12 is to separate the culture supernatant from cells and cell debris. Purification tube 14, also called a purification column, operates primarily based on ion exchange and adsorption mechanisms. The purification column is filled with ion exchange resins, which have specific chemical groups that can exchange ions with those in the water. Specifically, cations (such as Na+) are transferred to the resin, while H+ ions from the resin enter the water, thus achieving ion replacement. Similarly, anions (such as Cl-) are replaced by OH- ions from the resin, generating H2O. This ion exchange process allows the purification column to effectively remove ions from the water, thereby achieving purification.
[0037] When it is necessary to clamp the purification tube 14 during use, first insert the purification tube 14 into the horizontal plate 13. Then, by rotating the threaded rod 25, because the threaded rod 25 is threadedly connected to the horizontal plate 13 and the ring 24 is restricted from rotating due to being fitted on the outer wall of the tube body 21, the horizontal plate 13 moves downwards while the threaded rod 25 rotates, pushing the ring 24 downwards. This causes the ring 24 to squeeze the clamping block 23, which rotates inside the tank 22 and clamps the purification tube 14 on one side, keeping it stable.
[0038] In some embodiments, the clamping assembly 2 further includes a knob 26 disposed on the top of the threaded rod 25.
[0039] When in use, the design of the knob 26 makes it easy to grip and control the rotation of the threaded rod 25. At the same time, the grooves on the surface of the knob 26 can increase friction and prevent slippage.
[0040] In some embodiments, the clamping assembly 2 further includes: the bottom end of the upright 27 passes through the horizontal plate 13 and is connected to the ring 24.
[0041] When in use, the design of the upright 27 can stabilize the ring 24 and allow it to move downwards steadily.
[0042] In some embodiments, the clamping assembly 2 further includes a stop 28 disposed on the top of the upright 27.
[0043] The design of the stop 28 during use ensures that it will not detach from the clamp 23 when the ring 24 moves downward.
[0044] In some embodiments, the clamping assembly 2 further includes an arc-shaped plate 29 disposed on the outer side wall of the clamping block 23.
[0045] When in use, the arc-shaped plate 29 is designed to fit better against the outer wall of the purification tube 14, thereby better clamping the purification tube 14.
[0046] In some embodiments, a support assembly 3 is provided at the bottom of the housing 11. The support assembly 3 includes: an internally threaded tube 31 rotatably disposed on the inner side wall of the bottom of the housing 11; a second threaded rod 32 disposed inside the internally threaded tube 31 and threadedly connected to the internally threaded tube 31; a rectangular rod 33 disposed inside the second threaded rod 32 and with its bottom end passing through the second threaded rod 32 and connected to the housing 11; and a top plate 34 disposed on the top of the second threaded rod 34.
[0047] When the top of the purification tube 14 cannot reach the hose at the bottom of the filter box 12 during use, the internal threaded tube 31 can be rotated. While rotating, it is threadedly connected to the second threaded rod 32. The second threaded rod 32 is restricted from rotating by the rectangular rod 33. Therefore, when the internal threaded tube 31 rotates, it can push the top plate 34 to move upward to support the purification tube 14.
[0048] In some embodiments, the support assembly 3 further includes a baffle 35 disposed on the top of the rectangular rod 33.
[0049] The design of the baffle 35 during use ensures that the threaded rod 32 will not detach from the internal threaded tube 31 when it rises.
[0050] In some embodiments, the support assembly 3 further includes: multiple levers 36, all disposed on the outer side wall of the internally threaded tube 31.
[0051] When in use, the lever 36 is designed to facilitate the rotation of the internally threaded tube 31.
[0052] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," and "some examples" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.
[0053] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.
