Description

Technical Field

[0001] This utility model relates to the field of reaction tube technology, specifically a reaction tube with protective function. Background Technology

[0002] Freeze-dried microspheres refer to small, uniformly shaped solid spheres formed by rapidly freezing reagents or drug solutions into liquid nitrogen using a specialized precision micro-pump at extremely low temperatures for a very short time. These microspheres are then collected and stored in a small freeze-drying device. Freeze-dried microspheres are often added using reaction tubes, which are laboratory consumables used in bacterial culture and identification processes. These tubes are products that utilize the typical biochemical reaction characteristics of bacteria on these consumables to identify bacterial genera.

[0003] Currently, lyophilized microspheres are often stored inside reaction tubes, with a sealing cap separating the inside and outside of the tube to protect them from contamination and improve the accuracy of laboratory bacterial culture data.

[0004] Because the freeze-dried microspheres in this type of storage reaction tube are small in diameter, light, and have extremely low water content, they are prone to static electricity and thus adhere to the sealing cap. When the cap is opened, the freeze-dried microspheres are easily lost along with the cap. Utility Model Content

[0005] Therefore, it is necessary to provide a reaction tube with protective function to address the problems of lyophilized microspheres being lost with the cap and difficulties in sample addition in the existing technology.

[0006] To achieve the objective, this utility model adopts the following technical solution:

[0007] The present invention discloses a reaction tube with a protective function, comprising a tube body and a tube cap:

[0008] The tube body and the tube cap are limited by a fixing component. The tube body has one or more freeze-dried microspheres and an obstruction ball inside. The sum of the diameters of the freeze-dried microspheres and the obstruction ball is larger than the inner diameter of the tube body. The obstruction ball is located between the tube cap and the freeze-dried microspheres.

[0009] Furthermore, the fixing component includes an elastic block, which is installed on the inner wall of the tube cap, and a slot is opened on the side of the tube body, with each slot cooperating with the elastic block.

[0010] Furthermore, multiple elastic blocks are provided, and the cross-section of each elastic block adopts a hemispherical structure. The shape of the elastic block is adapted to the shape and number of the slots.

[0011] Furthermore, the fixing component includes a locking block and a lever, the side of the lever is rotatably connected to the tube cap, the end of the lever is connected to the locking block, and a locking groove is formed on the side of the tube body, the locking groove engaging with the locking block.

[0012] Furthermore, a torque spring is provided at the rotatable connection between the lever and the cap.

[0013] Furthermore, receiving compartments are provided on both sides of the inner wall of the tube cover, and the locking block can be stored in the receiving compartments.

[0014] Furthermore, the side of the tube cap has two grooves, which are symmetrically distributed and have a rectangular cross-section.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] This invention features a structural design in which an obstruction ball is placed above the lyophilized microspheres. The obstruction ball is positioned between the lyophilized microspheres and the cap, preventing the lyophilized microspheres from sticking to the cap due to static electricity, which would cause the lyophilized microspheres to be lost when the cap is opened. At the same time, the gravity of the obstruction ball presses down on the lyophilized microspheres, preventing the lyophilized microspheres from being suspended by static electricity and thus preventing the sample liquid from failing to submerge the lyophilized microspheres.

[0017] This invention involves adding the sample through the gap between the obstruction ball and the tube body. The sample liquid falls into the bottom of the tube from the gap. During the sample addition process, the obstruction block blocks the sample addition needle, preventing the sample addition needle from directly contacting the lyophilized microspheres and thus preventing the loss of the lyophilized microspheres.

[0018] This utility model features a structure with an elastic block on the inner wall of the tube cap. During installation, the elastic block is inserted into the slot to fix the tube cap and tube body, preventing accidental opening of the tube cap and loss of the freeze-dried microspheres inside. During disassembly, the tube cap is flattened by squeezing its two sides, causing the elastic block to bulge outward and disengage from the slot, thus separating the tube cap and tube body.

[0019] This utility model uses a lever and a locking block structure design. A torque spring applies a force into the locking block to fix the tube body and the tube cap together. The lever is rotated to bring the locking block out of the locking block, thereby separating the tube cap and the tube body. Attached Figure Description

[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0028] Example 1

[0029] This embodiment describes a reaction tube with protective functions, such as... Figure 1 As shown, it includes a tube body 1 and a tube cap 2. The tube body 1 and the tube cap 2 are limited by a fixing component, forming a sealed space to prevent external air from entering the tube body 1 and contaminating the sample inside the tube body 1. Two grooves 9 are opened on the side of the tube cap 2. The two grooves 9 are symmetrically arranged to facilitate the gripping of the instrument handle.

[0030] like Figure 2 As shown, tube 1 contains one or more lyophilized microspheres 3. Because the lyophilized microspheres 3 are injected into liquid nitrogen through a professional precision micro-pump, they are rapidly frozen into small, uniformly shaped solid spheres at extremely short and low temperatures. They are then collected and stored in a small lyophilization device. Therefore, the lyophilized microspheres 3 are dry and have extremely low water content, making them prone to static electricity. Due to their small diameter and light weight, the lyophilized microspheres 3 are easily affected by static electricity. When the static electricity is high, the lyophilized microspheres 3 will adhere to the inside of the tube cap 2. When the tube cap 2 is opened, the lyophilized microspheres 3 are easily lost along with the cap. When the static electricity is low, the lyophilized microspheres 3 will float in the container, making it difficult to add samples. If the sample tip touches the lyophilized microspheres 3, the lyophilized microspheres 3 will be lost.

[0031] To avoid the above phenomenon, a barrier ball 4 is provided inside the tube body 1. The barrier ball 4 is located between the tube cap 2 and the freeze-dried microsphere 3. The sum of the diameters of the freeze-dried microsphere 3 and the barrier ball 4 is larger than the inner diameter of the tube body 1, so the freeze-dried microsphere 3 cannot be moved out from the gap between the barrier ball 4 and the tube body 1.

[0032] This embodiment describes a reaction tube with a protective function. During use, the barrier ball 4 presses down on the lyophilized microspheres 3, blocking the path between the lyophilized microspheres 3 and the tube cap 2, preventing the lyophilized microspheres 3 from sticking to the tube cap 2. At the same time, the barrier ball 4 uses gravity to press the lyophilized microspheres 3 to the bottom of the tube body 1, preventing the lyophilized microspheres 3 from suspending due to electrostatics, thus facilitating sample addition by the sample dispensing needle. The barrier ball 4 also prevents the sample dispensing needle from touching the lyophilized microspheres 3, thus preventing loss.

[0033] Example 2

[0034] like Figure 2 As shown, the fixing component includes two elastic blocks 10, each of which is installed on the inner wall of the tube cap 2. A slot 5 is opened on the side of the tube body 1, and each slot 5 is connected to the elastic block 10. The cross-section of the slot 5 is rectangular. The shape and number of the elastic blocks 10 and the slot 5 are adapted to each other. The tube cap 2 and the tube body 1 are fixed together by the elastic blocks 10 being locked in the slot 5, thereby improving the stability of the tube cap 2 and preventing the tube cap 2 from being accidentally opened, which would cause the freeze-dried microspheres 3 inside the tube body 1 to be lost.

[0035] This embodiment describes a reaction tube with a protective function. During installation, the elastic block 10 is inside the clip 5, which can seal the reaction tube. During disassembly, the tube cover 2 is pressed from both sides where the elastic block 10 is not present, causing it to deform so that the two sides where the elastic block 10 is located bulge out, and the reaction tube can be opened at the position where the elastic block 10 is located.

[0036] Example 3

[0037] This embodiment introduces a reaction tube with a protective function, which has a basically the same structure as the reaction tube with a protective function introduced in Embodiment 2, the difference being: Figure 3-5 As shown, the fixing component includes a locking block 6, a lever 7, and a torque spring 8. The end of the lever 7 is connected to the locking block 6. The torque spring 8 is located at the rotatable connection between the lever 7 and the tube cap 2. The side of the tube body 1 has a locking groove 5, and each locking groove 5 is connected to the locking block 6. The side of the lever 7 is rotatably connected to the tube cap 2. The locking block 6 is inserted into the locking groove 5 to fix the tube body 1 and the tube cap 2, preventing accidental contact that could cause the tube body 1 and the tube cap 2 to separate, resulting in the loss of the freeze-dried microspheres 3 inside the reaction tube. The inside of the tube cap 2 has a receiving chamber, into which the locking block 6 can be stored. The receiving chamber provides space for the locking block 6 to detach from the locking groove 5. When locking the tube body 1 and the tube cap 2, the elastic force of the torque spring 8 fixes the locking block 6 in the locking groove 5. When separating the tube body 1 and the tube cap 2, pressing the lever 7 can separate the locking block 6 from the locking groove 5, thus separating the tube body 1 and the tube cap 2. Compared with embodiment two, it does not require deformation of the tube cap 2 and will not cause damage to the tube cap 2.

[0038] This embodiment describes a reaction tube with a protective function. During installation, the locking block 6 is locked in the locking groove 5 to seal the reaction tube. During disassembly, pressing the lever 7 separates the locking block 6 from the locking groove 5 to open the reaction tube.
