Description

Technical Field

[0001] This utility model relates to the field of stem cell reagent kit technology, specifically to an autologous cartilage tissue stem cell reagent kit that is easy to replace. Background Technology

[0002] A reagent kit is a box used to hold chemical reagents for detecting chemical components, drug residues, virus types, etc. It is generally used by hospitals and pharmaceutical companies. The purpose of reagent kits is to free laboratory personnel from the tedious process of reagent preparation and optimization. Therefore, reagent kits are usually equipped with corresponding instructions for use. Users can obtain satisfactory results by following the instructions with little or no optimization.

[0003] A search revealed Chinese patent CN216444096U, which discloses a rapid autologous stem cell separation kit, relating to the field of reagent kit technology. This rapid autologous stem cell separation kit includes a kit body and a lid. A first fixing frame and a second fixing frame are fixedly connected within the kit body. The first and second fixing frames have a first placement hole and a second placement hole, respectively. Reagents are placed in the second placement hole, a third placement hole, and the first placement hole. The lid is then closed to seal the kit body. When the lid is closed, a connecting drive device is activated, which in turn drives a threaded rod to rotate. This rotation of the threaded rod then pushes the second placement hole to move horizontally. As the fixing frame moves horizontally, it clamps and fixes the reagents, thus allowing for the clamping and fixing of various reagent types, making it more convenient to use and effectively improving the practicality of the kit.

[0004] However, the above design still has shortcomings. The test tubes are placed using a fixing bracket, but the fixing bracket is a fixed installation structure. When the fixing bracket breaks during use, it cannot be replaced, which makes it impossible to effectively place the test tubes and reduces the convenience of the kit.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an autologous cartilage tissue stem cell kit that is easy to replace, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an easily replaceable autologous cartilage tissue stem cell reagent kit, comprising a U-shaped plate, with support blocks fixedly connected to the four corners of the bottom of the U-shaped plate, multiple limiting grooves opened on both sides of the inner wall of the U-shaped plate, limiting sliders movably arranged inside the limiting grooves, pull blocks fixedly connected to the front end face of the limiting sliders, placement plates fixedly connected between two adjacent pull blocks, mounting cavities opened on the opposite sides of the two limiting sliders, limiting holes opened on the opposite sides of the two mounting cavities, limiting blocks movably arranged inside the limiting holes, moving plates fixedly connected to the opposite sides of the two limiting blocks, and second springs fixedly connected to the opposite sides of the two moving plates.

[0008] As a further embodiment of this utility model: the upper surface of the placement plate is provided with a plurality of placement holes, a sponge block is fixedly connected to the bottom of the placement hole, and a fixing plate is fixedly connected to the upper inside of the placement hole.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-4 An embodiment of this utility model provides: an easily replaceable autologous cartilage tissue stem cell kit, including a U-shaped plate 2, with support blocks 9 fixedly connected to the four corners of the bottom of the U-shaped plate 2, multiple limiting grooves 8 opened on both sides of the inner wall of the U-shaped plate 2, limiting sliders 3 movably arranged inside the limiting grooves 8, pull blocks 4 fixedly connected to the front end face of the limiting sliders 3, placement plates 7 fixedly connected between two adjacent pull blocks 4, installation cavities 23 opened on the side of the two limiting sliders 3 that are far apart from each other, limiting holes 27 opened on the side of the two installation cavities 23 that are far apart from each other, limiting blocks 26 movably arranged inside the limiting holes 27, moving plates 25 fixedly connected to the side of the two limiting blocks 26 that are close to each other, and second springs 24 fixedly connected to the side of the two moving plates 25 that are close to each other;

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, during use, when the placement plate 7 needs to be replaced, the limiting block 26 can be pressed to move it away from the limiting hole 27 and closer to the mounting cavity 23. When the limiting block 26 moves to the appropriate position, the pull block 4 is pulled outwards. The pull block 4 moves and causes the limiting slider 3 to slide in the limiting groove 8 until the limiting slider 3 disengages from the limiting groove 8, thus completing the disassembly of the placement plate 7. Similarly, when the placement plate 7 needs to be installed, the limiting block 26 is pressed again, and then the limiting sliders 3 on both sides of the placement plate 7 are slid into the limiting groove 8. The sliding of the limiting slider 3 causes the limiting block 26 to move. When the limiting block 26 moves... When the spring moves to the opposite side of the limiting hole 27, the second spring 24 is no longer subjected to external force and will drive the limiting block 26 to insert into the limiting hole 27, thereby completing the fixing of the limiting slider 3 and the installation of the placement plate 7. By making it easier to disassemble and assemble the placement plate 7, it is easier to place the test tube 12, thereby improving the convenience of the reagent kit. This solves the problem that when the test tube 12 is placed by the fixing bracket, but the fixing bracket is a fixed installation structure, if the fixing bracket breaks during use, it cannot be replaced, which makes it impossible to effectively place the test tube 12 and reduces the convenience of the reagent kit.

[0028] The upper surface of the placement plate 7 has multiple placement holes 15. A sponge block 16 is fixedly connected to the bottom of the placement hole 15. A fixing plate 14 is fixedly connected to the upper part of the placement hole 15. A fixing hole 13 is opened through the surface of the fixing plate 14. A test tube 12 is movably arranged inside the fixing hole 13. A limiting groove 19 is opened on the right side of the placement hole 15. A first spring 22 is fixedly connected to the bottom of the limiting groove 19. A connecting plate 21 is fixedly connected to the top of the first spring 22. A limiting rod 20 is fixedly connected to the top of the connecting plate 21. A limiting plate 18 is fixedly connected to the top of the limiting rod 20. A pull ring 17 is fixedly connected to the top of the limiting plate 18. A storage box 1 is fixedly connected to the top of the U-shaped plate 2. A movable door 6 is rotatably arranged on the front end of the storage box 1. Handles 5 are fixedly connected to both sides of the top of the storage box 1. The interior of the storage box 1 is divided into multiple placement cavities 10 by a partition plate. A placement box 11 is movably placed inside the placement cavity 10.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when placing the test tube 12, first move the pull ring 17 upwards. The movement of the pull ring 17 drives the limiting plate 18 to move. After the limiting plate 18 moves to a suitable height, place the test tube 12 into the fixing hole 13. Then slowly move the pull ring 17 downwards until the limiting plate 18 contacts the top of the test tube 12. At this time, the elasticity of the first spring 22 can be used to generate a downward squeezing force on the test tube 12. With the help of the sponge block 16, the two ends of the test tube 12 can be limited and protected, thereby improving the safety of the test tube 12 during placement.

[0030] Among them, the storage box 1, the movable door 6, the placement cavity 10 and the placement box 11 can be used to classify and place other instruments of the user, so as to make it easier for the user to use them.

[0031] Working principle: In this application, when the placement plate 7 needs to be replaced, the limiting block 26 can be pressed to move it away from the limiting hole 27 and closer to the mounting cavity 23. When the limiting block 26 moves to the appropriate position, the pull block 4 is pulled outward. The pull block 4 moves and causes the limiting slider 3 to slide in the limiting groove 8 until the limiting slider 3 disengages from the limiting groove 8, thus completing the disassembly of the placement plate 7. Similarly, when the placement plate 7 needs to be installed, the limiting block 26 is pressed again, and then the limiting sliders 3 on both sides of the placement plate 7 slide into the limiting groove 8. The sliding of the limiting sliders 3 causes the limiting block 26 to move. When the limiting block 26 moves to the opposite side of the limiting hole 27, the second spring 24 is no longer subjected to external force and will cause the limiting block 26 to insert. The test tube 12 is placed into the limiting hole 27, thereby fixing the limiting slider 3 and installing the placement plate 7. The placement plate 7 is easy to disassemble and assemble, making it easier to place the test tube 12, thus improving the convenience of the reagent kit. Secondly, when placing the test tube 12, first move the pull ring 17 upward. The movement of the pull ring 17 drives the limiting plate 18 to move. When the limiting plate 18 moves to a suitable height, place the test tube 12 into the fixing hole 13. Then slowly move the pull ring 17 downward until the limiting plate 18 contacts the top of the test tube 12. At this time, the elasticity of the first spring 22 can be used to generate a downward squeezing force on the test tube 12. With the help of the sponge block 16, the two ends of the test tube 12 can be limited and protected, thereby improving the safety of the test tube 12 during placement.
