Description

Technical Field

[0001] This utility model relates to the field of beverage cooling technology, specifically a leak-proof sample preservation tube for infectious disease extraction. Background Technology

[0002] Sample collection and preservation tubes are made of high-quality medical-grade PP / PE / PET plastic materials, featuring a leak-proof design, excellent sealing, stable material, various sizes, and resistance to high temperatures and pressures. The conical bottom design allows for easy sample collection, retrieval, and placement. They are widely used for the storage and transportation of various biological reagents and liquid samples. They can be used with inactivated and non-inactivated virus preservation solutions, physiological saline, cell preservation solutions, and sample preservation solutions. Preservation tubes are containers used in laboratories to store and preserve biological samples, chemical reagents, and other substances. Preservation tubes are typically made of polypropylene, which has good sealing performance and chemical stability. Preservation tubes are available in different volumes and shapes.

[0003] However, it still has some drawbacks. For example, when using leak-proof infectious disease sample preservation tubes, the traditional sample preservation tubes use simple rubber piston seals, which makes the airtightness relatively poor. This can easily lead to the leakage of infectious disease samples, affecting the external environment. In addition, people need to extract the samples again, which is not conducive to people's use.

[0004] To address the aforementioned issues, this application proposes a leak-proof infectious disease extraction sample preservation tube. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof sample preservation tube for infectious disease extraction, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof infectious disease sample preservation tube, comprising a test tube, wherein a supporting device is movably sleeved on the lower outer surface of the test tube, the supporting device comprising a limiting base, an expansion pad, a fixing block, a rotating shaft, a support plate, and a base column, wherein the limiting base is movably sleeved on the lower outer surface of the test tube, the expansion pad is fixedly connected to the inner wall of the limiting base, the fixing block is fixedly connected to the lower outer surface of the limiting base, the rotating shaft is rotatably connected to one side of the outer surface of the fixing block, the support plate is fixedly connected to the outer wall of the rotating shaft, and the base column is fixedly connected to the lower outer surface of the limiting base.

[0007] Preferably, a top cover is movably mounted on the upper outer surface of the test tube, and a soft piston is fixedly connected to the lower outer surface of the top cover.

[0008] Preferably, the inner wall of the test tube is fixedly fitted with a sealing device.

[0009] Preferably, the sealing device includes a rubber soft ring, a telescopic spring shaft, a first arc-shaped piece, a magnetic piece, a second arc-shaped piece, and a sealing rubber column. The inner wall of the test tube is fixedly fitted with the rubber soft ring, and the inner wall of the rubber soft ring is fixedly installed with the telescopic spring shaft.

[0010] Preferably, one end of the telescopic spring shaft is movably sleeved with an arc-shaped piece, and a magnet is fixedly installed on one outer surface of the arc-shaped piece.

[0011] Preferably, a sealing rubber column is movably connected to the inner wall of the first arc-shaped piece, and a second arc-shaped piece is fixedly connected to the outer wall of the sealing rubber column.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a sealing device to vertically insert a rubber soft ring into the inner wall of a test tube. By inserting the sample extractor into the gap between the first arc-shaped piece and the sealing rubber column, the first and second arc-shaped pieces are separated and opened. When an infectious disease sample enters the test tube, the sample extractor is pulled out, and the telescopic spring shaft returns to its original position, bringing the sample together. Simultaneously, the magnetic pieces on both sides attract each other and close, improving the airtightness of the device and preventing the leakage of infectious disease samples, thus eliminating the potential risk of infectious disease sample leakage.

[0014] This invention uses a support device to vertically insert test tubes into the inner wall of the expansion pad of the limiting base. The support plate is pushed outward by the rotation axis of the inner wall of the fixed block until the base column is in contact with the table. The support plate assists the base column in supporting the test tubes, improving the stability of test tube storage. It also eliminates the need for test tube racks, reduces the storage space for test tube samples, optimizes the functionality of the equipment, and meets various user needs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a leak-proof infectious disease extraction sample preservation tube, including a test tube 1. A supporting device 3 is movably sleeved on the lower outer surface of the test tube 1. The supporting device 3 includes a limiting base 6, an expansion pad 7, a fixing block 8, a rotating shaft 9, a support plate 10, and a base column 11. The limiting base 6 is movably sleeved on the lower outer surface of the test tube 1. The expansion pad 7 is fixedly connected to the inner wall of the limiting base 6. The fixing block 8 is fixedly connected to the lower outer surface of the limiting base 6. The rotating shaft 9 is rotatably connected to one side of the outer surface of the fixing block 8. The support plate 10 is fixedly connected to the outer wall of the rotating shaft 9. The base column 11 is fixedly connected to the lower outer surface of the limiting base 6. The expansion pad 7 can wrap and fix the test tube 1, improving its storage stability.

[0022] In this embodiment, as Figure 1-2 As shown, a top cover 2 is movably installed on the upper outer surface of the test tube 1, and a soft piston 4 is fixedly connected to the lower outer surface of the top cover 2. A sealing device 5 is fixedly fitted on the inner wall of the test tube 1. The soft piston 4 can simply seal the test tube 1, which is convenient for people to store infectious disease samples.

[0023] In this embodiment, as Figure 4 As shown, the sealing device 5 includes a rubber soft ring 12, a telescopic spring shaft 13, a first arc-shaped piece 14, a magnetic piece 15, a second arc-shaped piece 16, and a sealing rubber column 17. The rubber soft ring 12 is fixedly sleeved on the inner wall of the test tube 1. The telescopic spring shaft 13 is fixedly installed on the inner wall of the rubber soft ring 12. One end of the telescopic spring shaft 13 is movably sleeved on the first arc-shaped piece 14. A magnetic piece 15 is fixedly installed on one outer surface of the first arc-shaped piece 14. The sealing rubber column 17 is movably connected to the inner wall of the first arc-shaped piece 14.

[0024] Working principle:

[0025] Before use, a leak-proof infectious disease sample preservation tube allows the operator to first remove the soft piston 4 from the test tube 1 (top cap 2). The infectious disease sample is then placed inside the test tube 1 for storage, facilitating subsequent research. The test tube 1 is vertically inserted into the inner wall of the expansion pad 7 of the limiting base 6 via the supporting device 3. The support plate 10 is pushed outwards by the rotating shaft 9 on the inner wall of the fixing block 8 until the base column 11 is flush with the tabletop. The support plate 10, with its side assisting the base column 11, enhances the stability of the test tube 1 and eliminates the need for a test tube rack, reducing the storage space required for the sample in the test tube 1. The space is optimized to improve the functionality of the equipment and meet various user needs. Through the sealing device 5, the rubber soft ring 12 is vertically inserted into the inner wall of the test tube 1. By inserting the sample extractor into the gap between the first arc-shaped piece 14 and the sealing rubber column 17, the first arc-shaped piece 14 and the second arc-shaped piece 16 are separated and opened. When the infectious disease sample enters the test tube 1, the sample extractor is pulled out, and the telescopic spring shaft 13 will return to its original position and gather it together. At the same time, the magnetic pieces 15 on both sides will attract each other and close, improving the airtightness of the equipment and preventing the leakage of infectious disease samples, thus solving the hidden danger of infectious disease sample leakage.
