Description

Technical Field

[0001] This utility model relates to a sample preservation tube. Background Technology

[0002] Sample preservation tubes play a crucial role in nucleic acid testing. They provide a stable and suitable storage environment for collected swab samples, ensuring that the viral nucleic acid components in the samples are not degraded or denatured by external factors such as temperature, humidity, and microbial contamination before transportation and testing, thus guaranteeing the accuracy and reliability of the test results. Furthermore, sample preservation tubes prevent cross-contamination of samples during processing, ensuring the safety of testing personnel. Therefore, sample preservation tubes are an indispensable component of the nucleic acid testing process, and their quality directly affects the effectiveness and safety of the entire testing procedure.

[0003] Sample tubes are typically standalone devices for sample collection, usually with screw-on caps. They come in volumes ranging from 1 mL to 10 mL and various diameters. Sample preservation solution can be pre-filled inside the tubes. During sample collection, after collecting the sample with a swab, open the cap, insert the swab, and then tighten the cap. Once the sample is transported to the laboratory, the cap needs to be opened again, and the sample removed using a pipette for subsequent procedures such as nucleic acid extraction.

[0004] These sample tubes are suitable for manual operation. When used in automated testing systems, they require an automatic capping mechanism. Automatic capping mechanisms are often complex and costly, and are not suitable for small point-of-care testing (POCT) devices.

[0005] Therefore, a sample preservation tube is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the existing defects and provide a sample preservation tube that is easy to operate and suitable for automated operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sample preservation tube, comprising a tube body and a tube cap; an isolation component is provided in the middle of the tube cap; the upper end of the tube cap is used to connect to a sampling device, and the lower end is used to connect to the upper port of the tube body, thereby achieving the sealing of the tube body.

[0008] Preferably, the isolation component includes a sealing membrane connected to the inner middle of the tube cap, which, when connected to the upper port of the tube body, seals the tube body.

[0009] Preferably, the upper end of the outer wall of the pipe body is provided with an external thread, and the lower end of the pipe cap is provided with a first internal thread. The external thread and the first internal thread are adapted to achieve the connection between the pipe body and the pipe cap.

[0010] Preferably, the upper end of the inner wall of the tube cap is provided with a second internal thread for connecting the sampling device.

[0011] Preferably, the tube body is made of polypropylene.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: This sample preservation tube, with its double-screw cap and puncture-resistant membrane design, can be docked with the cartridge in a point-of-care testing device after sample collection. A pipette from the cartridge can directly puncture the tube cap to transfer the sample, thus completing sample processing and testing within the fully enclosed cartridge. This greatly simplifies sample transfer procedures in the laboratory and avoids the risks of sample leakage and contamination. It is easy to operate. Compared with ordinary sample preservation tubes, it is no different in general applications and is compatible with ordinary sample preservation tubes. It is suitable for automated operation. This sample preservation tube matches the matching automated point-of-care testing (POCT) cartridge, eliminating the need for manual sample transfer. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-3 As shown, a sample preservation tube includes a tube body 1 and a tube cap 2; an isolation component is provided in the middle of the tube cap 2; the upper end of the tube cap 2 is used to connect to a sampling device, and the lower end is used to connect to the upper port of the tube body 1, thereby achieving the sealing of the tube body 1.

[0017] Specifically, the isolation component includes a sealing membrane 3, which is connected to the inner middle of the tube cap 2. When the tube cap 2 is connected to the upper port of the tube body 1, it achieves the sealing of the tube body 1. The sealing membrane 3 can be punctured by a sharp object such as a pipette tip.

[0018] Specifically, an external thread 4 is provided on the upper end of the outer side wall of the pipe body 1, and a first internal thread 5 is provided on the lower end of the pipe cap 2. The external thread 4 and the first internal thread 5 are matched to achieve the connection between the pipe body 1 and the pipe cap 2. A good seal is formed at the spiral.

[0019] Specifically, a second internal thread 6 is formed on the upper inner wall of the tube cap 2 for connecting to the sampling device. It can be matched with the protruding tube-like interface screw of the card box of the point-of-care testing device or other automated sampling equipment, and a good seal is formed between the upper end of the tube cap and the interface after tightening. The helical directions of the first internal thread 5 and the second internal thread 6 are mirror images of each other, so that the direction of tightening the tube body to the tube cap is the same as the direction of tightening the tube cap to the interface.

[0020] Specifically, tube 1 is made of polypropylene. Other materials can also be used.

[0021] This sample preservation tube, with its dual-screw cap and puncture-resistant membrane design, can be docked with the cartridge in point-of-care testing (POCT) devices after sample collection. The pipette in the cartridge can directly puncture the tube cap to transfer the sample, thus completing sample processing and testing within the fully enclosed cartridge. This greatly simplifies sample transfer procedures in the laboratory and avoids the risks of sample leakage and contamination. It is easy to operate. Compared to ordinary sample preservation tubes, it is no different in general applications and is compatible with ordinary sample preservation tubes. It is suitable for automated operations. This sample preservation tube is matched with the corresponding automated point-of-care testing (POCT) cartridge, eliminating the need for manual sample transfer.
