Description

Technical Field

[0001] This invention belongs to the field of reagent kit technology, and in particular relates to a cell identification reagent kit that can prevent cross-contamination. Background Technology

[0002] A reagent kit is a box used to hold chemical reagents for detecting chemical components, drug residues, virus types, etc. In the process of cell identification, reagent kits are needed to store reagents containing cell samples in a unified manner to facilitate transportation and storage.

[0003] Chinese utility model patent CN223356225U discloses a cell identification kit that prevents cross-contamination. The kit uses a frame to group and store reagent tubes. Inside the frame is a storage space, and within that space are individual reagent storage units. Each reagent tube can be stored separately in its own unit. To retrieve or place a reagent tube, the frame is simply pulled out of the kit, and the corresponding storage unit is opened individually. This process avoids contact with reagent tubes in other storage units, thus preventing cross-contamination between cell samples and ensuring smooth and accurate cell identification.

[0004] Research revealed that the aforementioned devices use a pull-and-rotate mechanism for loading and unloading test tubes, lacking a locking function. This makes them prone to accidental slippage and opening, failing to meet the practical needs for safe storage of reagent tubes. Furthermore, retrieving a specific test tube requires pulling out the entire corresponding rack, which is inconvenient. Therefore, there is an urgent need to improve existing cell identification kits and provide a cell identification kit that prevents cross-contamination. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a cell identification kit that is reasonably designed, simple in structure, allows for individual storage of each test tube, prevents cross-contamination, and offers higher storage safety, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cell identification kit that prevents cross-contamination, comprising:

[0008] A storage box, wherein several storage cavities are evenly distributed inside the storage box, and each storage cavity is provided with a storage tube, and a support spring is provided between the bottom of the storage tube and the inner bottom surface of the storage cavity;

[0009] A limiting groove is formed on the inner wall of the receiving cavity, and a limiting block is fixed on the outer wall of the storage tube. The limiting block is engaged and slidably positioned in the corresponding limiting groove.

[0010] In a preferred embodiment, a vertical hole is provided inside the bottom end of the storage tube, and a positioning element is provided inside the vertical hole. The rotation range of the storage tube is 0-90°.

[0011] In a preferred embodiment, the positioning element includes a first positioning element and a second positioning element. The bottom end of the first positioning element is fixed to the inner bottom surface of the storage cavity, and the top end of the first positioning element extends into the vertical hole. The second positioning element is fixedly disposed on the inner wall of the vertical hole.

[0012] In a preferred embodiment, the first positioning member is movably connected to the storage tube, the first positioning member is a half-cylinder structure, and the second positioning member is a quarter-cylinder structure.

[0013] In a preferred embodiment, the upper end of the storage tube has an inner cavity, and limit baffles are attached to the inner walls at both ends of the inner cavity. The limit baffles are made of elastic rubber.

[0014] In a preferred embodiment, a circular groove is provided inside the top end of the storage tube, and a protrusion is provided in the middle of the circular groove.

[0015] In a preferred embodiment, the limiting groove includes a long vertical section, a short vertical section, and an arc-shaped horizontal section. The long vertical section and the short vertical section are located at the left and right ends of the arc-shaped horizontal section, respectively, and the three sections are connected.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the solution of this utility model:

[0018] This device arranges several relatively independent and non-interconnected storage cavities evenly inside the storage box, allowing multiple storage tubes to be embedded into each cavity in an orderly manner. This not only enables the independent storage of reagent tubes, effectively avoiding contact interference and cross-contamination risks between different reagent tubes and ensuring the stability of reagent storage, but also simplifies the process of taking out and putting in reagent tubes. No additional sorting or arrangement is required, significantly improving the ease of operation and greatly increasing the efficiency of reagent storage and retrieval.

[0019] The combination of the first and second positioning components limits the rotation adjustment range of the storage tube. By manually pressing the storage tube lightly, the outer wall limiting block moves down along the short vertical section to the arc-shaped horizontal section. Then, the storage tube can be manually rotated 90° counterclockwise, causing the limiting block to slide to the bottom of the long vertical section. After releasing the pressure, the elasticity of the support spring can push the storage tube to rise smoothly along the long vertical section, enabling rapid access to the reagent tube in the inner cavity. Similarly, the reverse operation allows the storage tube to retract stably and be hidden inside the storage cavity. This not only simplifies the process of retrieving and placing the reagent tube but also provides all-round protection for the reagent tube, avoiding collision damage during storage and operation, and ensuring the storage safety of the reagent tube.

[0028] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0029] like Figure 1-5 As shown, the cell identification kit of this invention, which prevents cross-contamination, comprises:

[0030] Storage box 1, the interior of storage box 1 has several storage cavities 3 evenly distributed, each storage cavity 3 is provided with a storage tube 2, and a support spring 5 is provided between the bottom of the storage tube 2 and the inner bottom surface of the storage cavity 3;

[0031] The limiting groove 4 is formed on the inner wall of the storage cavity 3, and the limiting block 9 is fixed on the outer wall of the storage tube 2. The limiting block 9 is engaged and slidably located in the corresponding limiting groove 4.

[0032] Based on the above structure, a vertical hole 6 is provided inside the bottom end of the storage tube 2, and a positioning component is provided inside the vertical hole 6. The rotation range of the storage tube 2 is 0-90°.

[0033] Based on the above structure, the positioning component includes a first positioning component 7 and a second positioning component 8. The bottom end of the first positioning component 7 is fixed to the inner bottom surface of the storage cavity 3, and the top end of the first positioning component 7 extends into the vertical hole 6. The second positioning component 8 is fixed on the inner wall of the vertical hole 6.

[0034] Based on the above structure, the first positioning element 7 is movably connected to the storage tube 2. The first positioning element 7 is a half-cylinder structure, and the second positioning element 8 is a quarter-cylinder structure.

[0035] In this embodiment, by using the first positioning member 7 with a half-cylinder structure and the second positioning member 8 with a quarter-cylinder structure, the rotation adjustment range of the storage tube 2 can be limited to between 0-90°.

[0036] Based on the above structure, an inner cavity 10 is provided inside the upper end of the storage tube 2. Limiting baffles 11 are attached to the inner walls at both ends of the inner cavity 10. The limiting baffles 11 are made of elastic rubber.

[0037] In this embodiment, the limiting baffle 11 made of elastic rubber material can limit the reagent tube stored in the inner cavity 10 and prevent it from falling off.

[0038] Based on the above structure, a circular groove 12 is provided inside the top of the storage tube 2, and a protrusion 13 is provided in the middle of the circular groove 12.

[0039] In this embodiment, the circular groove 12 and the protrusion 13 in the middle facilitate manual control of the rotation and adjustment of the storage tube 2.

[0040] Based on the above structure, the limiting groove 4 includes a long vertical section, a short vertical section and an arc-shaped horizontal section. The long vertical section and the short vertical section are located at the left and right ends of the arc-shaped horizontal section, respectively, and the three are connected.

[0041] In this embodiment, the opening of the limiting groove 4 facilitates the restriction of the rotation and lifting of the storage tube 2.

[0042] The working principle of this utility model is as follows:

[0043] In use, first install the reagent tube into the inner cavity 10 inside the upper end of the corresponding storage tube 2. The rubber limiting baffles 11 attached to the inner walls at both ends of the inner cavity 10 can restrain the reagent tube and prevent it from falling off. Then, manually press down on the storage tube 2 so that the limiting block 9 on its outer wall moves from the long vertical section of the limiting groove 4 to the arc-shaped horizontal section. Then, manually pinch the protrusion 13 in the circular groove 12 to control the storage tube 2 to maintain its current height position and rotate it 90° clockwise so that the limiting block 9 on the outer wall of the storage tube 2 moves to the other end of the arc-shaped horizontal section. Then release the pressure. At this time, under the action of the support spring 5, the storage tube 2 can be slightly raised so that the limiting block 9 is stably engaged in the short vertical section of the limiting groove 4, thus achieving the positioning of the storage tube 2. The storage tube 2 can be stably retracted and hidden inside the storage cavity 3. This not only makes the reagent tube loading and unloading process convenient, but also provides all-round protection for the reagent tube, avoiding collision damage during storage and operation, and ensuring the storage safety of the reagent tube.

[0044] The storage box 1 has several relatively independent and non-interconnected storage cavities 3 evenly distributed inside, which facilitates the orderly arrangement and installation of multiple storage tubes 2. This not only realizes the independent storage of reagent tubes, effectively avoiding the risk of contact interference and cross-contamination between different reagent tubes and ensuring the stability of reagent storage, but also simplifies the process of taking out and putting in reagent tubes. No additional sorting or arrangement is required, which significantly improves the convenience of operation and greatly improves the efficiency of reagent storage and retrieval.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
