Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental apparatus technology, and more specifically, to an apparatus for fixing dialysis samples. Background Technology
[0002] Dialysis bags are frequently used consumables in routine experiments involving dialysis fluid replacement and small molecule removal. The samples to be processed are placed in dialysis bags of different sizes, and the two ends are sealed with dialysis clamps or centrifuge tubes and placed in a container with dialysis fluid. However, during dialysis, the dialysis bags often float on the liquid, with their surfaces exposed to the air, affecting the dialysis effect. At the same time, the dialysis bags are also prone to falling off. Since a magnetic stirrer is needed to accelerate the dialysis process during dialysis experiments, adding a rotor poses a risk of the rotor hitting the dialysis bag, causing leakage and increasing the uncontrollable factors in the experiment.
[0003] In summary, how to provide an effective device for immobilizing dialysis samples is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a device for fixing dialysis samples, which can effectively fix the dialysis samples in the dialysis container, avoid the dialysis samples being exposed to the air, improve the dialysis effect, and reduce the risk of the rotor coming into contact with the dialysis bag.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An apparatus for immobilizing dialysis samples, comprising:
[0007] A base plate, the bottom of which is equipped with several supporting legs;
[0008] A partition, the partition being located above the base plate;
[0009] A connector is located between the base plate and the partition plate and is used to lock the base plate and the partition plate at a preset distance.
[0010] Furthermore, in this invention, both the base plate and the partition are circular structures, and there are at least two connecting members, which are evenly distributed along the axis of the base plate.
[0011] Furthermore, the connector can be detachably connected to both the base plate and the partition plate.
[0012] Furthermore, the preset distance between the base plate and the partition plate is adjustable.
[0013] Furthermore, the length of the connecting member is adjustable.
[0014] Furthermore, the connector is a cylindrical structure, and both the base plate and the partition plate are provided with threaded holes. The connector is detachably connected to the base plate and the partition plate through the threaded holes.
[0015] Furthermore, the connector includes several connecting posts, and the several connecting posts are detachably connected.
[0016] Furthermore, the surface of the connector (4) is marked with a scale.
[0017] Furthermore, the bottom plate and the partition plate are provided with a plurality of liquid passage holes.
[0018] Furthermore, the present invention provides a counterweight block installed on the base plate below the base plate.
[0019] Furthermore, this utility model also includes:
[0020] A clamping member is mounted on the base plate and is used to fix the base plate.
[0021] The device for fixing dialysis samples provided by this utility model involves connecting and fixing a base plate and a partition plate with connectors, and setting a preset distance between the base plate and the partition plate. The preset distance can be determined and fixed according to different dialysis sample sizes, thus enabling the base plate and partition plate to effectively fix different dialysis samples, which helps to improve the stability of dialysis sample fixation. During dialysis, the device is placed in the dialysis container, and the rotor is first placed at the bottom of the dialysis container. Several support legs on the base plate can create a certain gap between the base plate and the bottom of the dialysis container, which facilitates the rotation of the rotor. It can satisfy both static and dynamic dialysis. During dynamic dialysis, it can also be used in various types of stirrers and can be used for dialysis of multiple samples of different specifications.

[0028] 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.
[0029] The core of this invention is to provide a device for fixing dialysis samples, which can effectively fix the dialysis samples in the dialysis container, prevent the dialysis samples from being exposed to the air, improve the dialysis effect, and reduce the risk of the rotor coming into contact with the dialysis bag.
[0030] Please refer to Figures 1-3 A device for fixing dialysis samples includes a base plate 2, a partition plate 1, and a connector 4. Several support legs 3 are installed at the bottom of the base plate 2. The partition plate 1 is located above the base plate 2. The connector 4 is located between the base plate 2 and the partition plate 1 and is used to fix the preset distance between the base plate 2 and the partition plate 1.
[0031] It should be noted that in this embodiment of the present invention, the base plate 2 and the partition plate 1 can adopt any shape and structure, such as a disc shape, a rectangle, or a polygonal structure, and can also be customized according to the shape of the container used for dialysis.
[0032] In addition, the connector 4 in this embodiment of the present invention can adopt any structure, which only needs to connect the base plate 2 and the partition plate 1 and maintain a preset distance between the base plate 2 and the partition plate 1.
[0033] In addition, the base plate 2, partition plate 1 and connector 4 in this embodiment of the present invention can be made of any material, such as metal, nylon, PVC, etc.
[0034] Optionally, in some embodiments, in order to further reduce damage to the dialysis sample, the base plate 2, the partition 1, and the connector 4 are all made of nylon.
[0035] In use, the base plate 2 and the partition plate 1 are connected and fixed by the connector 4, and a preset distance is set between the base plate 2 and the partition plate 1. The preset distance can be determined and fixed according to different dialysis sample sizes. Therefore, the base plate 2 and the partition plate 1 can effectively fix different dialysis samples, which is beneficial to improving the fixation stability of the dialysis samples. During dialysis, the device is placed in the dialysis container, and the rotor is placed at the bottom of the dialysis container first. Several support legs 3 on the base plate 2 can make a certain gap between the base plate 2 and the bottom of the dialysis container, which facilitates the rotation of the rotor. It can satisfy both static and dynamic dialysis. During dynamic dialysis, it can also be used in various types of stirrers and can be used for dialysis of multiple samples of different specifications. At the same time, it can avoid the rotor contacting the dialysis bag and tearing the dialysis bag, reducing sample loss and material waste, ensuring the consistency of the dialysis process of different batches of samples, and reducing batch-to-batch differences.
[0036] Please refer to Figures 1-3 In some embodiments, both the base plate 2 and the partition 1 are circular structures, and there are at least two connectors 4, which are evenly distributed along the axis of the base plate 2. That is to say, both the base plate 2 and the partition 1 are circular structures. Dialysis containers are mostly beakers, which is convenient for dialysis. At least two connectors 4 can also ensure the stability of the position of the partition 1 to the greatest extent and avoid overturning.
[0037] Optionally, in some embodiments, the diameter of the base plate 2 and the partition plate 1 is 12-15cm. Since the dialysis beakers are mostly 1L-3L beakers, and the diameter of a 1L-3L beaker is 12cm-16cm, the 12cm specification can be used universally. A gap of 1-2cm will be left on both sides, which will not affect the use.
[0038] Optionally, in some embodiments, the number of connectors 4 can be determined according to the specific structure of the connectors 4. For example, when the connectors 4 adopt a rope structure, at least two can be used, preferably at least three, which can better stabilize the partition 1.
[0039] Optionally, in some embodiments, the connector 4 can be detachably connected to the base plate 2 and the partition 1. That is, with the detachable connection, when it is necessary to change different dialysis samples, it is only necessary to detach the partition 1 from the connector 4 and the partition 1 can be removed. This makes it convenient for the user to change the dialysis sample, avoiding the need to remove the entire device for replacement, making it more convenient for the user and improving experimental efficiency.
[0040] In the above embodiments, the connector 4 can be detachably connected to the base plate 2 and the partition plate 1, which makes it convenient for users to clean the device after dialysis, so that the device can be reused and costs are reduced.
[0041] Optionally, in some embodiments, the connector 4 can be detachably connected to the base plate 2 and the partition plate 1 by means of snap-fit connection, damping connection, threaded connection, etc.
[0042] Optionally, in some embodiments, the preset distance between the base plate 2 and the partition 1 is adjustable. That is, by adjusting the preset distance between the base plate 2 and the partition 1, the use of different dialysis samples can be met, reducing the cost for users to prepare multiple sizes of fixing devices.
[0043] Optionally, in some embodiments, the preset distance between the base plate 2 and the partition 1 can be adjusted by the connector 4. For example, when the connector 4 adopts a rod-shaped structure, the partition 1 is provided with a connecting hole, and the connecting rod is inserted into the connecting hole. The preset distance between the base plate 2 and the partition 1 can be adjusted by sliding the partition 1 on the connecting rod. Therefore, in the above method, the connecting hole and the connecting rod adopt damped sliding, so that even if the partition 1 changes position, the preset distance between the base plate 2 and the partition 1 can be kept fixed.
[0044] In other embodiments, the partition 1 is provided with a magnet, and the connector 4 is a rod-shaped structure made of iron material. Therefore, when the partition 1 is moved, the position of the connector 4 and the partition 1 can be fixed by the magnet, which is more convenient and faster.
[0045] In other embodiments, the length of the connector 4 is adjustable, that is, the preset distance between the base plate 2 and the partition 1 is adjusted by adjusting the length of the connector 4.
[0046] Optionally, in some embodiments, the connector 4 adopts a telescopic rod structure, that is, the length of the connector 4 is adjusted by the telescopic rod structure.
[0047] In other embodiments, the connector 4 is a cylindrical structure, and threaded holes 6 are provided on both the base plate 2 and the partition plate 1. The connector 4 is detachably connected to the base plate 2 and the partition plate 1 through the threaded holes 6. That is to say, the connector 4 is detachably connected to the base plate 2 and the partition plate 1 through the threaded connection, which is more convenient and faster, and the connection method is more reliable.
[0048] In other embodiments, the connector 4 includes several connecting posts, and the several connecting posts are detachably connected. That is, by connecting the ends of the several connecting posts, i.e., adjusting the number of interconnected connecting posts, the purpose of adjusting the preset distance between the base plate 2 and the partition plate 1 can be achieved.
[0049] In other embodiments, two connecting posts may be used. Specifically, one connecting post is hollow, and the other connecting post is threaded together with it. By screwing, the overlap length of the two connecting posts can be changed, thereby adjusting the preset distance between the base plate 2 and the partition plate 1.
[0050] In other embodiments, the connector 4 can be a rope structure, that is, the base plate 2 and the partition 1 can be fixedly connected by a nylon rope, which is less expensive and allows for quick and easy adjustment of the distance between the base plate 2 and the partition 1.
[0051] In the above embodiment, in order to make it easier to adjust the distance between the base plate 2 and the partition 1, one end of the connector 4 is fixedly connected to the base plate 2, and the partition 1 is provided with a connection hole. The rope passes through the connection hole and is knotted to realize the connection between the base plate 2 and the partition 1.
[0052] In the above embodiment, the connector 4 is provided with a rope buckle. When it is necessary to adjust the distance between the base plate 2 and the partition 1, the position of the rope buckle can be adjusted by pressing and moving the rope buckle, thereby achieving the purpose of adjusting the distance between the base plate 2 and the partition 1.
[0053] Optionally, in some embodiments, the surface of the connector is marked with graduations to facilitate precise height adjustment by the user.
[0054] Please refer to Figures 1-3 In some embodiments, both the base plate 2 and the partition plate 1 are provided with a number of liquid passage holes 5, which facilitates the rapid entry and exit of the dialysis fluid when it is replaced.
[0055] Optionally, in some embodiments, the diameter of the liquid passage 5 is less than 1 cm.
[0056] Optionally, in some embodiments, a counterweight is provided below the base plate 2 and mounted on the base plate 2. Adding the counterweight can increase the overall weight of the device and ensure that the device can remain stable inside the dialysis container.
[0057] Optionally, in some embodiments, in order to further improve the stability of the device inside the dialysis container, the base plate 2 is provided with a clamping member. Specifically, the clamping member adopts a structure with elastic deformation function. Through its deformation function, when the base plate 2 enters the dialysis container, the elastic member deforms and presses against the dialysis beaker, thereby fixing the device.
[0058] In other embodiments, a suction cup may be mounted on the base plate, which contacts the dialysis container to secure the device.
[0059] Optionally, in some embodiments, the clamping element is made of rubber or silicone and is installed on the peripheral wall of the base plate 2. The rubber or silicone greatly improves the stability of the device through its strong friction.
[0060] Optionally, in some embodiments, a clamping mechanism is also included for clamping the open end of the dialysis bag. The clamping mechanism includes a pair of adjustable clamping plates, the inner sides of which are covered with anti-slip pads (such as silicone or rubber) to increase friction and prevent the dialysis bag sample from slipping out.
[0061] In the above embodiments, the clamping mechanism is installed on the partition plate. The clamping mechanism is opened and closed by a spring or a threaded knob. The user can adjust the clamping force according to the thickness of the dialysis bag to ensure that the clamping is firm and does not damage the dialysis bag.
[0062] Optionally, in some embodiments, auxiliary lateral support rods are also included. The lateral support rods can be deployed as needed to increase the lateral stability of the device. Specifically, the lateral support rods are mounted on the connectors, and the number of lateral support rods can be adjusted according to different usage requirements.
[0063] In the above embodiments, for larger dialysis bags, the side support rods in the auxiliary support structure are deployed to limit and fix the dialysis bag, thereby ensuring the stability of the dialysis bag during the dialysis process.
[0064] In other words, the key point of this utility model embodiment is that: the base plate 2 and the partition plate 1 are connected and fixed by the connector 4, and a preset distance is set between the base plate 2 and the partition plate 1. The preset distance can be determined and fixed according to different dialysis sample sizes. Therefore, the base plate 2 and the partition plate 1 can effectively fix different dialysis samples, which is beneficial to improving the fixation stability of the dialysis samples. During dialysis, the device is placed in the dialysis container, and the rotor is placed at the bottom of the dialysis container first. Several support legs 3 on the base plate 2 can make a certain gap between the base plate 2 and the bottom of the dialysis container, which facilitates the rotation of the rotor. At the same time, it can meet the requirements of static and dynamic dialysis. During dynamic dialysis, it can also be used in various types of stirrers and can be used for dialysis of multiple samples of different specifications. At the same time, it can avoid the rotor contacting the dialysis bag and tearing the dialysis bag, reducing sample loss and material waste, ensuring the consistency of the dialysis process of different batches of samples, and reducing batch-to-batch differences.
[0065] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0066] The present invention provides a detailed description of a device for fixing dialysis samples.

The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the present invention.
