TECHNICAL FIELD

[0001] The utility model is suitable for sample detection technical field, provide a kind of sample storage and transport cup. BACKGROUND

[0002] In the field of medical experiments, PCR 8-way tubes are widely used for sample storage and transportation. PCR 8-way tubes are usually composed of multiple independent small tubes, which can simultaneously contain different samples and perform experimental operations therein. The design structure enables effective separation and identification of samples, avoiding cross-contamination. In addition, PCR 8-way tubes are used to store biological samples such as blood, tissue, and cells in molecular biology experiments, particularly in operations such as nucleic acid extraction and PCR amplification.

[0003] In some cases, samples in PCR 8-way tubes need to be refrigerated and transported in a low-temperature environment. This usually occurs when it is necessary to maintain the biological activity of the samples or prevent the degradation of the samples. For example, nucleic acid samples and cell samples are very sensitive to temperature, and excessive temperature can cause damage or failure of the samples. Therefore, during storage and transportation, samples are often placed in a low-temperature environment, such as a refrigeration box or an ice bag, to ensure their stability and the accuracy of experimental results.

[0004] Currently, sample storage and transportation usually use storage and transport boxes. Due to the large volume of storage and transport boxes, they are usually used to store multiple PCR 8-way tubes and other experimental materials. Although storage and transport boxes can provide a large storage space, due to their large size, when the number of samples is not large, independent PCR 8-way tubes are often inconvenient for experimental personnel to carry and carry between different experimental departments, increasing the workload of experimental personnel. INVENTION CONTENTS

[0025] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0026] PCR8 manifold is a special consumable for molecular biology experiments. Referring to the attached Figure 4 PCR8 manifold is composed of eight connected small tubes, and the body is made of high-quality polypropylene material, which has good chemical stability and heat resistance. PCR8 manifold is commonly used for DNA or RNA amplification, suitable for various types of PCR experiments and for short-term storage of PCR products or other biological samples.

[0027] See Figures 1-7 The purpose of this utility model is to provide a sample storage and transportation cup, including a cylindrical sample bottle 1, a cup lid 2 detachably connected to the top of the sample bottle 1, and a sample cage 3 installed at the bottom of the cup lid 2.

[0028] Specifically, sample vial 1 is a thermos flask, with insulation layers inside its side walls and bottom. These layers are filled with insulating material or vacuum-sealed to prevent heat exchange between the inside and outside of sample vial 1, thus keeping the inside of sample vial 1 warm. The lid 2 is equipped with a pressure relief screw cap 21 and an explosion-proof valve 22.

[0029] Specifically, a gas outlet is fixedly connected to the top of sample bottle 1, and a detachable pressure relief cap 21 is threaded onto the gas outlet. Both the gas outlet and the pressure relief cap 21 have mating threads, which are notched threads. When the pressure relief cap 21 is tightened, a sealed space is formed between the cap and the gas outlet, preventing gas from easily escaping. When the cap is loosened, the inner bottom of the cap separates from the top of the gas outlet, allowing pressurized airflow to overflow from the notched thread between the cap and the outlet, thus equalizing the pressure inside and outside the bottle. The explosion-proof valve 22 is existing technology. Its principle is that a spring force presses the valve disc against the valve seat. When the pressure inside the bottle rises above a set value, the pressure acts on the valve disc, overcoming the spring force and causing the valve disc to lift upwards, opening the valve and releasing excess pressure. Its specific structure will not be described in detail here.

[0030] The sample cage 3 is detachably connected to the bottom of the cup lid 2. The sample cage 3 is a cylindrical metal cage with a mounting groove 33. A sample connecting tube 4 is snapped onto the sample cage 3. The sample connecting tube 4 includes snap-fit ​​parts 41 installed at both ends along its length. Specifically, the snap-fit ​​part 41 is an annular structure located at both ends of the sample connecting tube 4 (PCR8 connecting tube) with a through hole in the middle. Both ends of the mounting groove 33 along its length are provided with elastic hooks 331 that cooperate with the snap-fit ​​parts 41. The elastic hooks 331 can pass through the snap-fit ​​parts 41, thereby achieving snap-fit ​​with the sample connecting tube 4.

[0031] In use, this device allows for the filling of sample vial 1 with a cooling substance such as dry ice to maintain a low temperature. Simultaneously, the experimenter uses the specially designed sample connecting tube 4 to hold the experimental material, which is then installed on the sample cage 3. The sample cage 3 is then integrated with the lid 2, and the sample cage 3 is inserted into the sample vial 1. After installation, a gap exists between the bottom of the sample cage 3 and the inner bottom of the sample vial 1, allowing for the containment of solid substances such as dry ice. Finally, the lid 2 is installed on the sample vial 1. At this point, the temperature inside the sample vial 1 is maintained at a low temperature due to the cooling substance such as dry ice. Furthermore, the thermal insulation layer ensures that the device can store and transport samples at low temperatures for a certain period. During the process, the dry ice evaporates and absorbs heat, causing the internal gas to expand. At this point, the pressure is released by using the pressure relief screw cap 21 grams to make the device easier to open.

[0032] Preferably, the top of the sample bottle 1 is provided with a second threaded portion 101, and the inner side wall of the cup lid 2 is provided with a fourth threaded portion 201 that mates with the second threaded portion 101. The cup lid 2 and the sample bottle 1 are connected by the mating thread of the fourth threaded portion 201 and the second threaded portion 101.

[0033] Preferably, the sample cage 3 has a first threaded portion 301 at one end near the cup lid 2, and a connecting ring 23 is fixedly connected to the inner top of the cup lid 2. The inner sidewall of the connecting ring 23 has a third threaded portion 231 that matches the first threaded portion 301. The sample cage 3 and the cup lid 2 are threadedly connected through the cooperation of the first threaded portion 301 and the third threaded portion 231. This allows the sample cage 3 to be detachable from the cup lid 2, facilitating subsequent cleaning.

[0034] Preferably, the sample cage 3 has a perforated grid 34 on its side. The perforated grid 34 can enhance the permeability of the sample cage 3, enabling it to cool down more quickly.

[0035] Preferably, the top and bottom of the sample cage 3 are respectively provided with a first mesh portion 31 and a second mesh portion 32. The first mesh portion 31 and the second mesh portion 32 can further enhance the permeability of the sample cage 3, enabling faster cooling.

[0036] In summary, in practical use, the experimenter first installs the PCR8 tubes onto the sample cage 3, securing them together via the engagement of the snap-fit ​​part 41 and the elastic hook 331. Then, by rotating, the sample cage 3 is integrated with the lid 2. Next, the sample cage 3 is inserted into the sample vial 1, and the lid 2 is rotated to integrate with the sample vial 1. At this point, under the action of refrigerants such as dry ice, the temperature inside the sample vial 1 is maintained at a low temperature. Simultaneously, with the assistance of the thermal insulation jacket, the device can ensure low-temperature storage and transportation of samples for a certain period. During storage and transportation, the evaporation of some ice absorbs heat, causing internal gas expansion. The explosion-proof valve 22 automatically releases excess pressure when it becomes too high, ensuring safe use. Before removing the PCR8 tubes, the pressure relief cap 21 can be loosened to release internal pressure, making the device easier to open.

[0037] Therefore, this device solves the problem of inconvenient handling caused by the large size of the storage and transportation box through its compact cup design. The cylindrical sample vial 1 is small in size, making it convenient for researchers to carry individual PCR 8-tube bundles between different experimental departments when the number of samples is small, significantly reducing workload. Meanwhile, the thermal insulation design of the sample vial 1 maintains a low internal temperature environment, the explosion-proof valve 22 ensures pressure safety, and the pressure relief cap 21 facilitates opening the device. The special structure of the sample cage 3 facilitates the installation and fixation of the sample bundles 4, achieving efficient and safe low-temperature storage and transportation of biological samples in the PCR 8-tube bundles 4, meeting the special storage and transportation environment requirements of PCR 8-tube samples in medical experiments.

[0038] 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.
