Description

Technical Field

[0001] This application relates to the field of biochemical dialysis experiments, specifically to a dialysis clamp fixation device. Background Technology

[0002] Dialysis is a classic separation and purification technique based on the principles of molecular diffusion and selective permeability of semi-permeable membranes. Its core process involves placing a sample solution containing the substances to be separated into a dialysis bag made of a semi-permeable membrane material (such as regenerated cellulose or cellulose acetate), and immersing the dialysis bag in a dialysis solution (usually a buffer solution) with specific components and ionic strength. Because the semi-permeable membrane only allows small molecules and ions to pass through while retaining the target macromolecules, driven by a concentration gradient, small molecule impurities in the sample (such as salts, detergents, and inhibitors) diffuse into the dialysis solution, while the target macromolecules remain inside the bag, thus achieving the purpose of desalting, buffer replacement, or purification.

[0003] In routine laboratory procedures, dialysis bags containing samples are typically sealed and secured at both ends using dialysis clips. Currently, commercially available dialysis clips are mostly made of plastic or polymer, characterized by their lightweight, low cost, and ease of use. However, this lightweight characteristic presents a significant problem in practical applications: because the average density of the dialysis clip is much lower than that of the dialysate (usually an aqueous solution), after the dialysis apparatus is placed in the container, the dialysis clip easily carries one end of the dialysis bag or the entire bag and floats on the surface of the dialysate. This results in part of the dialysis bag and its sample not being completely submerged. In this area, the sample cannot form an effective liquid-liquid contact and mass exchange interface with the dialysate, severely affecting dialysis efficiency. Furthermore, excessively high local sample concentrations or environmental differences may even lead to the inactivation or denaturation of target macromolecules.

[0004] Furthermore, to accelerate the diffusion rate of molecules and ions during dialysis and shorten the time required to reach equilibrium, the dialysate is often magnetically stirred or other circulation devices are used during experiments. While this externally driven fluid movement increases efficiency, it also exacerbates the collisions and friction between dialysis bags. Prolonged or intense friction can easily cause tiny scratches or even ruptures on the surface of the dialysis bags, leading to sample leakage into the dialysate.

[0005] Therefore, there is an urgent need for an improved fixing device that can effectively solve the problems in the existing technology, such as the dialysis clamps easily floating, resulting in insufficient sample immersion, and the dialysis bags easily breaking due to friction during the stirring process. Utility Model Content

[0006] In view of the above problems, this application provides a dialysis clip fixing device, which overcomes or at least partially solves the problems of the dialysis clip easily floating, resulting in insufficient sample immersion, and the dialysis bag easily breaking due to friction during stirring.

[0007] This application provides a dialysis clip fixing device, including: a horizontal plate, at least two cantilever arms, at least two dialysis clip sleeves, an adjusting sleeve, and a first tightening bolt. When there are two cantilever arms, they are designated as a first cantilever arm and a second cantilever arm; when there are two dialysis clip sleeves, they are designated as a first dialysis clip sleeve and a second dialysis clip sleeve. The first ends of the first and second cantilever arms are fixed to the horizontal plate, and the second ends of the first and second cantilever arms are suspended in the air.

[0008] Both the first dialysis clip and the second dialysis clip include a first clip plate, a second clip plate, a third clip plate, and a fourth clip plate. The first clip plate, the second clip plate, the third clip plate, and the fourth clip plate enclose each other to form a receiving cavity. The fourth clip plate is disposed opposite to the first clip plate and has a notch.

[0009] Both ends of the first jacket plate are provided with adjusting sleeves, and the adjusting sleeves are provided with first through holes. The first end of the first jacket plate is suspended from the first cantilever through the first through hole, and the second end of the first jacket plate is suspended from the second cantilever through the first through hole.

[0010] The first jacket plate is provided with a first threaded hole. When the dialysis clip fixing device is in use, the dialysis clips that hold the two ends of the dialysis bag are the first dialysis clip and the second dialysis clip, respectively. The first dialysis clip and the second dialysis clip are inserted into the receiving cavity of the first dialysis clip sleeve and the receiving cavity of the second dialysis clip sleeve, respectively. The notch is used for the dialysis bag to pass through. The first tightening bolt passes through the first threaded hole and abuts against the dialysis clip, so that the dialysis clip is fixed between the first tightening bolt and the fourth jacket plate.

[0011] The dialysis clip fixing device provided in this embodiment can be fully immersed in the dialysis fluid. The first tightening bolt passes through the first threaded hole and abuts against the dialysis clip, fixing the dialysis clip between the first tightening bolt and the fourth clip plate. In this way, neither the first nor the second dialysis clip, which holds both ends of the dialysis bag, is prone to floating, and the dialysis bag and its sample are completely submerged in the dialysis fluid. Furthermore, when there are two dialysis clip sleeves, the first and second dialysis clip sleeves together fix one dialysis bag. Similarly, when there are four dialysis clip sleeves (first, second, third, and fourth), the first and second dialysis clip sleeves together fix one dialysis bag, and the third and fourth dialysis clip sleeves together fix another dialysis bag. The two dialysis bags do not interfere with each other spatially and will not be damaged due to friction. Therefore, the dialysis clip fixing device provided in this embodiment can improve the reliability, safety, and efficiency of the dialysis process.

[0012] In one alternative embodiment, the device further includes a second tightening bolt, and the adjusting sleeve is provided with a second threaded hole. The second tightening bolt passes through the second threaded hole and abuts against the second cantilever to fix the adjusting sleeve to the second cantilever.

[0013] In this way, the dialysis clip sleeve can be fixed at different positions on the cantilever by adjusting the second tightening bolt, thereby adjusting the gap between the first dialysis clip sleeve and the second dialysis clip sleeve so that the adjusted gap can adapt to dialysis bags of different lengths.

[0014] In one alternative embodiment, the device also includes a handle that is fixed to the crossbar.

[0015] The dialysis clamp fixing device can be easily pulled up by the handle.

[0016] In one alternative embodiment, the device further includes a telescopic longitudinal support and a base, the telescopic longitudinal support being connected to the cross plate and the base.

[0017] By adjusting the retractable longitudinal support, the handle can be made higher than the surface of the dialysate, further ensuring that the sample in the dialysis bag can be completely immersed in the dialysate.

[0018] In one alternative configuration, the base is provided with a second through hole.

[0019] By providing a second through-hole, the stir bar can be used to drive the fluid movement near the dialysis bag.

[0020] In an alternative embodiment, the device further includes a counterweight disposed on the base.

[0021] By adding counterweights, the weight of the device can be increased, further ensuring that the sample in the dialysis bag can be completely immersed in the dialysis fluid.

[0022] In one alternative embodiment, the device further includes a clamp, wherein the first ends of the first and second cantilever arms are fixed to the cross plate by the clamp.

[0023] In one alternative, the clamp is connected to the horizontal plate, the clamp is provided with a threaded hole, and the first ends of the first cantilever and the second cantilever are provided with threads, the threads and the threaded hole are engaged to fix the first cantilever and the second cantilever to the horizontal plate by the clamp.

[0024] In one alternative approach, when there are multiple cantilever arms and dialysis clips, two adjacent cantilever arms form a pair, and multiple dialysis clips are either suspended on a pair of cantilever arms or dispersedly suspended on multiple pairs.

[0039] Figure 1 This is a schematic diagram of the structure of a dialysis clip fixing device provided in some embodiments of this application. Figure 2 This is a partial structural schematic diagram of a dialysis clip fixing device provided in some embodiments of this application. Figure 3 This is a schematic diagram of the structure of a dialysis clip fixing device in use, provided for some embodiments of this application. Figure 4 This is a schematic diagram illustrating the structure of a dialysis clip sleeve and an adjusting sleeve in a dialysis clip fixing device provided for some embodiments of this application. (Reference) Figure 1 , Figure 2 , Figure 3 and Figure 4 A dialysis clip fixing device includes: a horizontal plate 01, at least two cantilever arms, at least two dialysis clip sleeves, an adjusting sleeve 02, and a first tightening bolt 03. When there are two cantilever arms, they are designated as a first cantilever arm 04 and a second cantilever arm 05; when there are two dialysis clip sleeves, they are designated as a first dialysis clip sleeve 06 and a second dialysis clip sleeve 07. The first ends of the first cantilever arm 04 and the second cantilever arm 05 are vertically fixed to the horizontal plate 01, and the second ends of the first cantilever arm 04 and the second cantilever arm 05 are suspended in the air.

[0040] The first dialysis clip 06 and the second dialysis clip 07 both include a first clip plate 08, a second clip plate 09, a third clip plate 10 and a fourth clip plate 11. The first clip plate 08, the second clip plate 09, the third clip plate 10 and the fourth clip plate 11 surround each other to form a receiving cavity 12. The second clip plate 09 and the third clip plate 10 are arranged opposite each other, and the fourth clip plate 11 is arranged opposite to the first clip plate 08. The fourth clip plate 11 is provided with a notch 13.

[0041] Both ends of the first jacket plate 08 are provided with adjustment sleeves 02, and the adjustment sleeves 02 are provided with first through holes. The first end of the first jacket plate 08 is suspended from the first cantilever 04 through the first through hole, and the second end of the first jacket plate 08 is suspended from the second cantilever 05 through the first through hole, so that the first dialysis clip 06 and the second dialysis clip 07 are suspended from the first cantilever 04 and the second cantilever 05.

[0042] The first jacket plate 08 is provided with a first threaded hole, for reference. Figure 3 When the dialysis clip fixing device is in use, the dialysis clips that hold the two ends of the dialysis bag 14 are the first dialysis clip 15 and the second dialysis clip 16, respectively. The first dialysis clip 15 and the second dialysis clip 16 are slid into the receiving cavity 12 of the first dialysis clip sleeve 06 and the receiving cavity 12 of the second dialysis clip sleeve 07 from the side, respectively. The notch 13 is used for the dialysis bag 14 to pass through. The first tightening bolt 03 passes through the first threaded hole 0 and abuts against the dialysis clip, so that the dialysis clip is fixed between the first tightening bolt 03 and the fourth sleeve plate 11.

[0043] For example, Figure 3 The diagram shows the structure when there are 9 dialysis clips, and 4 of them are designated as the first dialysis clip sleeve 06, the second dialysis clip sleeve 07, the third dialysis clip sleeve 17, and the fourth dialysis clip sleeve 18. Figure 3 The diagram illustrates the situation where the third dialysis clip sleeve 17 and the fourth dialysis clip sleeve 18 fix the first dialysis clip 15 and the second dialysis clip 16.

[0044] In practical applications, if there are multiple dialysis bags 14, one dialysis bag 14 can be secured to every two dialysis clips. For example, Figure 3The nine dialysis clamps can secure four dialysis bags 14, and the dialysis bags 14 will not interfere with each other spatially. If the dialysis bag 14 is long, to prevent the dialysis bag 14 from contacting the bottom of the container 19 and causing damage, the first dialysis clamp sleeve 06 and the fourth dialysis clamp sleeve 18 can also be used to secure the first dialysis clamp 15 and the second dialysis clamp 16.

[0045] In some embodiments, when there are multiple cantilever arms and dialysis clips, two adjacent cantilever arms form a pair, and multiple dialysis clips are either suspended from a pair of cantilever arms or distributed across multiple pairs. For example... Figure 2 The diagram illustrates a configuration with four cantilever arms, designated as cantilever 04, cantilever 05, cantilever 20, and cantilever 21. The diagram shows multiple dialysis clips suspended from a pair of cantilever arms, cantilever 04 and cantilever 05. In practical use, if there are many dialysis bags 14, the multiple dialysis clips can be dispersed and suspended from cantilever 04, cantilever 05, cantilever 20, and cantilever 21.

[0046] When using the dialysis clip fixing device provided in this embodiment, the entire device can be completely immersed in the dialysis fluid 22. The first tightening bolt 03 passes through the first threaded hole and abuts against the dialysis clip, which can fix the dialysis clip between the first tightening bolt 03 and the fourth clip plate 11, and can be compatible with dialysis clips of different sizes. In this way, the first dialysis clip 15 and the second dialysis clip 16 holding both ends of the dialysis bag 14 are not easy to float, and the sample in the dialysis bag 14 can be completely immersed in the dialysis fluid 22. Moreover, when there are two dialysis clip sleeves, the first dialysis clip sleeve 06 and the second dialysis clip sleeve 07 are used to fix one dialysis bag 14 together. By analogy, when there are four dialysis clip sleeves, namely the first dialysis clip sleeve 06, the second dialysis clip sleeve 07, the third dialysis clip sleeve 17, and the fourth dialysis clip sleeve 18, the first dialysis clip sleeve 06 and the second dialysis clip sleeve 07 together secure one dialysis bag 14, and the third dialysis clip sleeve 17 and the fourth dialysis clip sleeve 18 together secure another dialysis bag 14. The two dialysis bags 14 will not interfere with each other spatially and will not be damaged due to friction. Therefore, the dialysis clip fixing device provided in this embodiment can improve the reliability, safety, and efficiency of the dialysis process.

[0047] In some embodiments, the device further includes a second tightening bolt 23, and the adjusting sleeve 02 is provided with a second threaded hole. The second tightening bolt 23 passes through the second threaded hole and abuts against the second cantilever 05, so that the adjusting sleeve 02 is fixed to the second cantilever 05. For example... Figure 2The diagram shows that the adjusting sleeve 02 above the second cantilever 05 has a second threaded hole, and the second tightening bolt 23 passes through the second threaded hole and abuts against the second cantilever 05. In practical applications, the adjusting sleeve 02 above the first cantilever 04 can also have a second threaded hole, and the second tightening bolt 23 passes through the second threaded hole and abuts against the first cantilever 04, so that the dialysis clamp sleeve can be more stably fixed to the first cantilever 04 and the second cantilever 05.

[0048] Thus, by adjusting the second tightening bolt 23, the dialysis clip sleeves can be fixed at different positions on the cantilever, thereby adjusting the distance between the first dialysis clip sleeve 06 and the second dialysis clip sleeve 07 to accommodate dialysis bags 14 of different lengths. Simultaneously, increasing the distance between the second dialysis clip sleeve 07 and the third dialysis clip sleeve 17 by adjusting the second tightening bolt 23 further ensures that no friction occurs between adjacent dialysis bags 14. Decreasing the distance between the second dialysis clip sleeve 07 and the third dialysis clip sleeve 17 by adjusting the second tightening bolt 23 allows for the installation of more dialysis clip sleeves on the first cantilever 04 and the second cantilever 05, thereby enabling the device to secure more dialysis bags 14.

[0049] In some embodiments, the device further includes a handle 24, which is fixed to the horizontal plate 01.

[0050] The handle 24 makes it easy to pull up the dialysis clamp fixing device.

[0051] In some embodiments, the device further includes a telescopic longitudinal support and a base 26, which are connected to the horizontal plate 01 and the base 26.

[0052] For example, the telescopic longitudinal support may include an inner rod 251, an outer rod 252, and a third fastening bolt 253. The inner rod 251 is placed inside the outer rod 252. Both the inner rod 251 and the outer rod 252 are provided with multiple threaded holes 254. The inner rod 251 is connected to the cross plate 01, and the outer rod 252 is connected to the base 26. In use, the inner rod 251 can move within the outer rod 252 in a direction closer to / away from the base to shorten / extend the telescopic longitudinal support. After moving to the appropriate position, one of the threaded holes 254 on the inner rod 251 and one of the threaded holes 254 on the outer rod 252 are aligned and tightened with the third fastening bolt 253. The appropriate position means that the handle 24 can be exposed in the dialysis fluid 22 to facilitate pulling up the dialysis clamp fixing device from the dialysis fluid 22, and the sample in the dialysis bag 14 can be completely immersed in the dialysis fluid 22 without the dialysis bag 14 contacting the base 26. The retractable longitudinal support can control the depth of the dialysis bag 14 immersed in the dialysate 22 and the space between it and the bottom of the container 19, mitigating the influence of temperature and other factors on the sample dialysis process. The entire device can be completely removed from the dialysate 22 via the handle 24 for easy replacement of the dialysate 22.

[0053] Figure 5 This is a schematic diagram of a base structure provided in some embodiments of this application. The base 26 may be provided with a second through hole 261. By providing the second through hole 261, the stir bar 27 can drive the fluid movement near the dialysis bag 14 through the second through hole 261. It is worth noting that this application does not limit the number and shape of the second through holes 261. There may be multiple second through holes 261, and the second through holes 261 may be any one or more of the following: circular, triangular, square, etc. The base 26 may also be a frame structure.

[0054] In some embodiments, the device may further include a counterweight 28 disposed on the base 26.

[0055] By setting a counterweight 28, the weight of the device can be increased, further ensuring that the sample in the dialysis bag 14 can be completely immersed in the dialysis fluid 22.

[0056] In some embodiments, the device may further include a clamp 29, with the first ends of the first cantilever 04 and the second cantilever 05 fixed to the horizontal plate 01 by the clamp 29.

[0057] For example, clamp 29 is connected to horizontal plate 01. Clamp 29 is provided with threaded holes. The first ends of the first cantilever 04 and the second cantilever 05 are provided with threads. The threads and threaded holes are matched so that the first cantilever 04 and the second cantilever 05 are fixed to the horizontal plate 01 by clamp 29.

For example, in the claims, any of the claimed embodiments can be used in any combination.

[0059] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
