Description

Technical Field

[0001] This utility model relates to the field of isothermal amplification detection technology, specifically to a centrifuge tube adapted for color-based specific identification. Background Technology

[0002] Currently, with the advancement of technology, specific identification after isothermal amplification has become a routine method used by technicians. The most common method is identification by fluorescence, because fluorescence only requires a simple centrifuge tube with a body and a cap, which avoids opening the cap and aerosol contamination. However, the use of fluorescence requires specialized fluorescence detection equipment. To address this, those skilled in the art have developed various color recognition methods that allow identification by simply observing the color inside the centrifuge tube, without the need for fluorescence detection equipment. However, these color recognition methods require opening the cap after amplification and adding the reaction substrate, often in two separate additions, which can easily lead to contamination.

[0003] Based on this, those skilled in the art urgently need to develop a new type of centrifuge tube that can be adapted to color recognition methods and has a simple structure suitable for mass production. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects existing in the prior art, thereby providing a centrifuge tube adapted for specific identification based on color.

[0005] A centrifuge tube adapted for color-based specific identification includes a first cap, a first tube body, a second tube body, and a third tube body arranged sequentially from top to bottom; and a second cap is also fitted onto the outer wall of the second tube body.

[0006] The first cover and the first tube are connected;

[0007] The first cover and the second tube are threaded together so that the sidewalls of the first tube and the second tube are slidably connected when the first cover and the second tube are threaded together.

[0008] The second cover is threadedly connected to the third tube.

[0009] Two discharge ports are opened at different heights on the side wall of the first tube, which are connected to the two cavities inside the first tube.

[0010] The height of each discharge port is adapted to the height of the third tube and the threaded connection height of the first cover and the second tube.

[0011] Preferably, the second tube has a double-ended opening structure and is divided into a fixed section and an extension section from top to bottom;

[0012] The outer wall of the fixed section is provided with external threads that are compatible with the internal threads provided on the inner wall of the first cover.

[0013] The extension section and the fixed section are fixedly connected to the top of the second cover.

[0014] Preferably, the length of the extension of the second tube is adapted to the length of the third tube.

[0015] Preferably, the interior of the first tube includes: a first cavity, a partition, a second cavity, and a first solid portion;

[0016] The first solid part, with a sloping top surface, is fixed to the bottom surface inside the first tube.

[0017] Inside the first tube:

[0018] The inner walls of the first cavity are formed by the inner walls of one side of the J-shaped separator and the one side of the first tube.

[0019] The wall of the second cavity is formed by the other side of the J-shaped partition entity, the top surface of the first entity, and the inner wall of the other side of the first tube.

[0020] Preferably, the first cover and the first tube are threaded together.

[0021] Preferably, the top of the first cover has a sample feeding through hole; the top of the first tube is fixedly connected to the wall of the sample feeding through hole.

[0024] The first discharge port and the first cavity are connected in a continuous manner;

[0025] The second discharge port is connected to the second cavity.

[0026] Preferably, a graduated scale is provided on the wall of the third tube.

[0027] The technical solution of this utility model has the following advantages:

[0028] This utility model device is simple and easy to operate, with low overall cost and easy production without special precision requirements. It does not require opening the cap when adding reaction substrates, and there is no risk of leakage after use. It is fully compatible with color recognition methods and does not require fluorescence detection equipment.

[0041] The first cover 1 and the first tube 2 are connected;

[0042] The first cover 1 and the first tube 2 are connected;

[0043] The first cover 1 and the second tube 3 are threaded together so that the sidewalls of the first tube 2 and the second tube 3 are slidably connected when the first cover 1 and the second tube 3 are threaded together.

[0044] The second cover 5 is threadedly connected to the third tube 4;

[0045] Two discharge ports are opened at different heights on the side wall of the first tube 2, which are connected to the two cavities inside the first tube 2.

[0046] The height of each discharge port is adapted to the height of the third tube 3 and the threaded connection height of the first cover 1 and the second tube 3.

[0047] Specifically:

[0048] The second tube 3 has a double-ended opening structure and is divided into a fixed section and an extension section from top to bottom;

[0049] The outer wall of the fixed section is provided with external threads that are compatible with the internal threads provided on the inner wall of the first cover 1;

[0050] The extension section and the fixed section are fixedly connected to the top of the second cover 5.

[0051] The length of the extension of the second tube 3 is adapted to the length of the third tube 4 and the liquid filling height.

[0052] The inner wall of the second cover 5 has an internal thread that matches the external thread at the top of the third tube 4.

[0053] In this embodiment, the first tube 2 includes: a first cavity 22, a partition, a second cavity 23, and a first solid portion 21;

[0054] The first solid part 21, with a sloping top surface, is fixed to the bottom surface inside the first tube 2;

[0055] Inside the first tube 2:

[0056] The inner walls of one side of the J-shaped separator and one side of the first tube 2 form the cavity wall of the first cavity 22;

[0057] The other side of the J-shaped partition entity, the top surface of the first entity 21, and the inner wall of the other side of the first tube 2 form the cavity wall of the second cavity 23.

[0058] In this embodiment, the two discharge ports are: the first discharge port 24 and the second discharge port 25.

[0059] The height of the first discharge port 24 is greater than the height of the second discharge port 25;

[0060] The first discharge port 24 and the first cavity 22 are connected through each other;

[0061] The second discharge port 25 and the second cavity 23 are connected through each other.

[0062] In this embodiment, the first cover 1 and the first tube 2 are threaded together.

[0064] The height of the first tube body 2>the height of the second tube body 3;

[0065] In practical applications:

[0066] Preparation:
