Description

Technical Field

[0001] This utility model applies to the field of sample testing equipment and provides a sample tube storage and transportation cup. Background Technology

[0002] In the field of medical experiments, PCR 8-tube bundles are widely used for sample storage and transportation. PCR 8-tube bundles typically consist of multiple independent tubes, capable of simultaneously holding different samples and performing experimental operations within them. Their design allows for effective sample separation and labeling, preventing cross-contamination. Furthermore, PCR 8-tube bundles are used in molecular biology experiments to store biological samples such as blood, tissues, and cells, playing a particularly important role in procedures such as nucleic acid extraction and PCR amplification.

[0003] In some cases, samples in 8-tube PCR kits need to be refrigerated and transported at low temperatures. This typically occurs when it is necessary to maintain the biological activity of the samples or prevent their degradation. For example, nucleic acid and cell samples are highly sensitive to temperature; excessively high temperatures can damage or degrade the samples. Therefore, samples are often placed in low-temperature environments, such as refrigerators or ice packs, during storage and transportation to ensure their stability and the accuracy of experimental results.

[0004] Currently, sample storage and transportation typically utilizes transport boxes. Due to their large size, these boxes are usually used to store multiple PCR 8-tube bundles and other experimental materials. While transport boxes offer ample storage space, their bulk makes it inconvenient for researchers to move and carry individual PCR 8-tube bundles between different departments when the number of samples is small, increasing their workload.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0027] PCR 8-tube strips are a special consumable used in molecular biology experiments. See appendix. Figure 3 and attached Figure 4PCR 8-tube bundles consist of eight interconnected tubes made of high-quality polypropylene, exhibiting excellent chemical stability and heat resistance. PCR 8-tube bundles are commonly used for DNA or RNA amplification and are suitable for various types of PCR experiments as well as for short-term storage of PCR products or other biological samples.

[0028] See Figure 1-6 The purpose of this utility model is to provide a sample connecting tube storage and transportation cup, including a cylindrical cup body 1, a cover 2 detachably connected to the top of the cup body 1, and a connecting tube fixing bracket 3 installed inside the cup body 1.

[0029] The cup body 1 has a thermos bottle structure. Specifically, its inner side wall has an insulation layer 12 for heat preservation. The insulation layer 12 is filled with insulation material or vacuum-treated to prevent heat exchange between the inside and outside of the cup body 1, thus keeping the inside of the cup body 1 warm. A pressure relief valve 201 is installed on the lid 2. The pressure relief valve 201 is existing technology. Its principle is that the valve disc is pressed against the valve seat by spring force. When the pressure inside the cup body 1 rises above the set value, the pressure acts on the valve disc, overcoming the spring force, causing the valve disc to lift upward, opening the valve, and releasing the excess pressure. Its specific structure will not be described in detail here.

[0030] The pipe fixing bracket 3 includes a first abutment part 31, a second abutment part 32, and a guide rail 33 installed between the two. A sampling pipe 4 is slidably connected to the guide rail 33, and the sampling pipe 4 is detachably connected to the guide rail 33. Specifically, the first abutment part 31 and the second abutment part 32 are the top and bottom structures of the pipe fixing bracket 3, respectively. The guide rail 33 is installed between the first abutment part 31 and the second abutment part 32. Two sets of guide rails 33 are symmetrically installed between the first abutment part 31 and the second abutment part 32, and each set of guide rails 33 includes two symmetrically arranged tracks, with a groove 331 on one side of each track that is close to the other. The sampling pipe 4 includes a top pipe ring 41 at the top, the outer edge of which can be inserted into the groove 331 to slide along it.

[0031] When using this device, two PCR8 tubes can be placed simultaneously. First, insert the individual tubes from one PCR8 tube into one set of guide rails 33. Then, invert and alternate the other set of PCR8 tubes with the first set, sliding them together until the second set of PCR8 tubes is inserted into the second set of guide rails 33, thus completing the installation of both sets of PCR8 tubes. Next, place a cooling substance into the container 1 to lower the temperature inside. Then, place the tube holder 3 inside the container 1, and finally close the lid to complete the storage of the PCR8 tubes.

[0032] Preferably, a support ring 13 is fixedly connected to the bottom of the cup body 1, and a receiving cavity 101 is provided between the support ring and the bottom of the cup body 1. When the connecting pipe fixing bracket 3 is installed inside the cup body 1, the bottom of the connecting pipe fixing bracket 3 will be supported by the support ring 13, thereby ensuring that a portion of space is always reserved at the bottom of the cup body 1 for placing cooling substances such as dry ice or ice packs.

[0033] Preferably, the top of the cup body 1 is provided with a first threaded portion 11, and the inner side of the lid body 2 is provided with a second threaded portion 21 that matches the first threaded portion 11. The lid body 2 and the cup body 1 are connected by the mating thread of the first threaded portion 11 and the second threaded portion 21.

[0034] Preferably, a partition net 321 is fixedly connected to the second abutment part 32. When the connecting pipe fixing bracket 3 is installed inside the cup body 1, the partition net 321 can block the refrigerant in the receiving cavity 101 to prevent the solid from rolling due to shaking during storage and transportation.

[0035] Preferably, the end of the first abutment 31 furthest from the guide rail 33 is fixedly connected to two symmetrical hinged parts 311. A handle 312 is hinged between the two hinged parts 311, and the handle 312 can rotate between the hinged parts 311. The operator can conveniently remove the connecting pipe fixing bracket 3 from the cup body 1 by pulling the handle 312.

[0036] Preferably, both the first abutment portion 31 and the second abutment portion 32 are provided with a flat bottom 301, specifically located on the side of the first abutment portion 31 and the second abutment portion 32 near the two guide rails 33. The design of the flat bottom 301 allows the tube fixing bracket 3 to be placed flat on the table and prevents it from rolling. At the same time, it allows the tube fixing bracket 3 to function as a PCR8 tube placement bracket, making it more convenient to use.

[0037] Preferably, an abutment ring 22 is fixedly connected to the inner top of the cover 2. When the cover 2 is installed on the cup body 1, it can abut downwards against the first abutment part 31 of the connecting tube fixing bracket 3. This makes the installation of the connecting tube fixing bracket 3 inside the cup body 1 more stable.

[0038] Preferably, a connecting part 34 is provided between the two sets of guide rails. Specifically, several connecting parts 34 may be provided between the two sets of guide rails. The connecting part 34 between the two sets of guide rails is used to make the structure of the connecting pipe fixing bracket 3 more stable.

[0039] In summary, during actual use, the operator first installs the two PCR8 tubes into the two sets of guide rails 33 of the tube holder 3 in a specific inverted and staggered manner. Then, a cooling substance, such as dry ice or an ice pack, is placed in the receiving cavity 101 at the bottom of the container 1. Next, the tube holder 3 containing the PCR8 tubes is placed inside the container 1. At this time, the bottom of the tube holder 3 is supported by the support ring 13, ensuring sufficient space at the bottom of the container 1 to hold the cooling substance, thereby ensuring the low-temperature preservation of the PCR8 tubes. The lid 2 with the pressure relief valve 201 is then placed on top, and the first threaded part 11 and the second threaded part 21 are engaged to achieve a threaded connection, ensuring the sealing of the container 1. After the lid 2 is installed, the abutment ring 22 at its inner top abuts downwards against the first abutment part 31 of the tube holder 3, further securing the tube holder 3 inside the container 1. If it is necessary to remove the PCR8 tubes, staff can easily remove the tube holder 3 from the cup body 1 by pulling the handle 312.

[0040] Furthermore, the mesh 321 on the tube holder 3 effectively prevents the cooling material from entering the internal space of the container 1, preventing solids from rolling due to shaking during storage and transportation. The flat bottom 301 of the tube holder 3 allows it to be placed stably on a table after removal, facilitating operation by staff. This device, through the combination of the insulation layer 12 and the cooling material in the container 1, provides a stable and low-temperature storage environment for the PCR8 tubes, effectively protecting the biological samples inside. Simultaneously, its unique tube holder 3 design not only facilitates the installation and removal of the PCR8 tubes but also improves the safety and convenience during storage and transportation.

[0041] Therefore, this device, through the thermal insulation design of the cup body 1 and the combined use of refrigerant, provides a stable and controllable low-temperature storage and transportation environment for PCR8 tubes. Simultaneously, the tube fixing bracket 3 structure not only facilitates the rapid installation and precise positioning of the PCR8 tubes, but also, through the cooperation of the guide rail 33 and the slide 331, ensures stable placement and convenient removal of the tubes, improving the efficiency of experimental operations. This device can be flexibly applied in various experimental scenarios, and is particularly suitable for the frequent handling and carrying of small quantities of PCR8 tubes between experimental departments, greatly reducing the workload of experimental personnel and improving the overall convenience and practicality of sample storage and transportation.

[0042] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
