Abstract
Description
Technical Field
[0001] This application relates to the field of tobacco detection technology, specifically to a portable testing kit for RPA-LFD test strips. Background Technology
[0002] In recent years, many "tobacco-like products," such as "tea cigarettes," have appeared on the market. Tea cigarettes are a type of "tobacco-like product" that does not contain plant-based tobacco. Testing is required to determine whether "tobacco-like products" on the market contain plant-based tobacco.
[0003] Because plant-derived tobacco possesses unique gene sequences, nucleic acid testing can be used to detect whether "tobacco-like products" contain plant-derived tobacco. Research has shown that recombinase polymerase amplification (RPA) technology combined with horizontal flow detection (LFD) strips allows for a simple detection process with visual interpretation of the results. This enables on-site testing of "tobacco-like products," offering advantages such as speed, convenience, efficiency, and high specificity.
[0004] However, the testing process requires carrying multiple testing components, such as centrifuges and test kits, which is inconvenient to carry, increases the complexity of travel, and affects testing efficiency. Utility Model Content

Similarly, depending on the context, the phrases "if determination" or "if monitoring (the stated condition or event)" can be interpreted as "when determination," "in response to determination," "when monitoring (the stated condition or event)," or "in response to monitoring (the stated condition or event)."
[0028] It should be noted that the directional terms such as "upper," "lower," "left," and "right" used in the description of the embodiments of this utility model are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model. In addition, in the context, it should also be understood that when it is mentioned that an element is formed "upper" or "lower" of another element, it can not only be formed directly "upper" or "lower" of the other element, but also indirectly "upper" or "lower" of the other element through an intermediate element.
[0029] Typically, the detection of whether "tobacco-like products" contain plant-derived tobacco is based on recombinase polymerase amplification (RPA) technology combined with lateral flow test strips (LFD). This process requires carrying multiple testing components, such as centrifuges and test kits, which is inconvenient to carry, increases the complexity of travel, and affects testing efficiency.
[0030] In this regard, refer to Figure 1 and Figure 2 This utility model provides a portable testing kit 100 for RPA-LFD test strips, which is based on recombinase polymerase amplification (RPA) technology combined with a lateral flow dipstick (LFD), abbreviated as RPA-LFD.
[0031] The testing chamber 100 includes a lower chamber 11, an upper chamber 12, a centrifuge 13, and multiple testing components (not shown in the figure).
[0032] An electrical connector 14 is provided on the side wall of the lower housing 11. The electrical connector 14 can be a USB interface or a Type-C interface.
[0033] A storage battery 15 is installed inside the lower housing 11. The storage battery 15 is connected to the electrical connector 14 for charging and power supply.
[0034] The upper housing 12 is located on top of the lower housing 11. The upper housing 12 can be detachably installed on top of the lower housing 11. Sealing components such as sealing rings can be provided between the upper housing 12 and the lower housing 11.
[0035] The upper housing 12 includes a shell 121 and a cover 122. The cover 122 is rotatably connected to the shell 121 and is used to open or close the shell 121. Multiple storage boxes 16 are provided inside the shell 121. The shell 121 has a top opening. The cover 122 can be connected to one side edge of the shell 121 via a rotating shaft. The cover 122 opens or closes the top opening of the shell 121 by flipping it over.
[0036] Centrifuge 13 is housed within housing 121 for connection to electrical connector 14. Centrifuge 13 can be a small centrifuge for centrifuging samples to be tested.
[0037] Multiple detection components are housed within the storage box 16. These components may include rapid test strips, rapid test kits, grinding rods, heating packs, pipettes, scissors, and beakers.
[0038] The storage box 16 can be made of a soft material to prevent wear and tear on the detection components inside.
[0039] When in use, the cover 122 can be opened to remove the component to be tested from the storage box 16. When the centrifuge 13 needs to be used, it can be electrically connected to the battery 15. With the cover 122 closed, operations can be performed on the cover 122.
[0040] By designing the testing box 100, the centrifuge 13 and multiple testing components are placed inside the testing box 100, and different testing components are stored in multiple storage boxes 16, which can improve portability, make testing more convenient, and improve testing efficiency.
[0041] In some embodiments, the plurality of storage boxes 16 and the housing 121 can be separate structures, with a gap C between the centrifuge 13 and at least one storage box 16; the inner wall of the cover 122 is provided with a limiting member 123, which is located in the gap C when the cover 122 closes the housing 121, and is interference-fitted with the centrifuge 13 and the storage box 16. When the limiting member 123 is interference-fitted with the centrifuge 13 and the storage box 16, the centrifuge 13 abuts against the inner wall of the housing 121, and the plurality of storage boxes 16 can also press against each other, with some storage boxes 16 abutting against the inner wall of the housing 121, that is, there is no movable gap between the storage box 16 and the centrifuge 13, between the plurality of storage boxes 16, and between the storage box 16 and the housing 121.
[0042] Multiple storage boxes 16 are separate from the housing 121, facilitating adjustment of their position within the housing 121 and easy removal. When the cover 122 closes the housing 121, the limiting member 123 is located in a gap C between the centrifuge 13 and at least one storage box 16, and is interference-fitted with both the centrifuge 13 and the storage box 16. This improves the stability of the centrifuge 13 and the storage box 16 during transport and reduces the risk of collision damage.
[0043] In some embodiments, the limiting member 123 is an air cushion.
[0044] The limiting component 123 is an air cushion with a certain amount of compression, which can play a good role in shock absorption and cushioning, further improving the stability of the centrifuge 13 and the storage box 16 during the carrying process.
[0045] In some embodiments, multiple detection components include rapid test strips, rapid test kits, grinding rods, heating packs, pipettes, scissors, and beakers; multiple storage boxes 16 include a rapid test strip storage box 161, a rapid test kit storage box 162, a grinding rod storage box 163, a heating pack storage box 164, a pipette storage box 164, a scissors storage box 166, and a beaker storage box 167. The rapid test strip storage box 161 and the heating pack storage box 164 are arranged along the length direction of the housing 11, and the centrifuge 13 and the rapid test strip storage box 161 and the heating pack storage box 164 are arranged along the width direction of the housing 11. The limiting member 123 is located between the rapid test strip storage box 161, the heating pack storage box 164, and the centrifuge 13.
[0046] The limiting member 123 is located between the rapid test strip storage box 161, the heating pack storage box 164 and the centrifuge 13, and can separate the rapid test strip storage box 161, the heating pack storage box 164 and the centrifuge 13, thereby reducing the risk of liquid contamination of the rapid test strips in the rapid test strip storage box 161 and the heating pack in the heating pack storage box 164 by the centrifuge 13.
[0047] In some embodiments, the outer surface of the rapid test strip storage box 161 is provided with a waterproof layer 1611.
[0048] By providing a waterproof layer 1611 on the outer surface of the rapid test strip storage box 161, the rapid test strip storage box 161 can be waterproofed and moisture-proof, reducing the risk of rapid test strip failure inside the rapid test strip storage box 161.
[0049] In some embodiments, the inner surface of the rapid test kit storage box 161 is provided with absorbent cotton 1612.
[0050] The rapid test kit storage box 161 has absorbent cotton 1612 on its inner surface. Even if moisture or liquid enters the rapid test kit storage box 161, the absorbent cotton 1612 can absorb the moisture, further reducing the risk of rapid test strips in the rapid test strip storage box 161 becoming ineffective.
[0051] In some embodiments, an illumination lamp 30 is provided on the inner sidewall of the cover 122, and the illumination lamp 30 is electrically connected to the battery 15.
[0052] The lighting 30 allows for operation even in dark environments, enhancing convenience.
[0053] In some embodiments, the top surface of the cover 12 is a plane.
[0054] The top surface of the cover 12 is flat and can be used as an operating table for easy operation.
[0055] In some embodiments, the cover 12 may also be provided with an observation window for easy observation.
[0056] It should be noted that the communication system provided in this embodiment corresponds to the technical solutions that can be used to execute the various method embodiments. Its implementation principle and technical effects are similar to those of the methods, and will not be repeated here.
[0057] The above description is merely a preferred embodiment of this utility model. Those skilled in the art should understand that the scope of disclosure involved in this utility model is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalent features without departing from the above-described concept.
