Technical Field
[0001] This invention belongs to the field of reagent kit technology, specifically relating to a human gene diagnostic reagent kit with a moisture-proof structure. Background Technology
[0002] Human gene diagnostic kits are a set of specialized testing tools based on gene detection technology, used for rapid and accurate analysis of human gene information. They typically contain core components such as gene extraction reagents, amplification reagents, probes, and reactive enzymes. Some kits also include specialized detection chips or reaction plates. Through standardized procedures, specific gene fragments are extracted, amplified, and analyzed from human samples (such as blood, saliva, and tissues). Finally, instruments are used to read information such as gene sequences, mutation sites, or expression levels.
[0003] The core function of these kits is to simplify the complex genetic testing process into standardized steps, which can be widely used in various scenarios: such as genetic disease screening (e.g., prenatal diagnosis of thalassemia and Down syndrome), tumor-related gene testing (to determine cancer driver gene mutations and the suitability of targeted drugs), identification of infectious disease pathogen genes (e.g., virus typing and drug resistance gene testing), and personalized medication guidance (to predict drug metabolism efficiency through gene polymorphism).
[0004] Existing reagent kits may have trace amounts of moisture remaining during assembly and sterilization. If not thoroughly dried, long-term storage can lead to reagent deterioration. Furthermore, in humid regions or during the rainy season, even if the reagent kit is unopened, the interior may still become damp after the outer packaging has been exposed to moisture.

[0025] 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.
[0026] Please see Figures 1-7 The present invention provides the following technical solution: a reagent kit with a moisture-proof structure, comprising a reagent kit body 1, a drying rack 2 fitted onto the inner wall surface of the reagent kit body 1, a first placement groove 3 opened on both sides of the top surface of the drying rack 2, a first limiting block 4 inserted into the surface of the first placement groove 3, the surface of the first limiting block 4 connected to both sides of the first drying plate 5, the surface of the first drying plate 5 fitted onto the inner wall of the first placement groove 3, a second placement groove 6 opened on both sides of the top surface of the drying rack 2, a second limiting block 7 inserted into the surface of the second placement groove 6, the surface of the second limiting block 7 connected to the second drying plate 8, the surface of the second drying plate 8 fitted onto the inner wall of the second placement groove 6, slots 9 symmetrically opened on the top surface of the drying rack 2, insert rods 10 fitted into the surface of the slots 9, the top surface of the insert rods 10 connected to the bottom of the top frame 11, a rectangular groove opened on the top surface of the top frame 11 fitted into and connected to the top drying plate 12, the top surface of the top drying plate 12 abutting against the bottom of the baffle 13, one side of the baffle 13 being rotatably connected to the top of the top frame 11 by a rotating shaft 14.
[0027] Preferably, the first placement groove 3 and the second placement groove 6 are both rectangular grooves with "T"-shaped groove structures on both sides, and their shape and size are adapted to the first limiting block 4, the first drying plate 5, the second limiting block 7, and the second drying plate 8.
[0028] In practical use, the first limiting block 4 and the second limiting block 7 connected on both sides of the first drying plate 5 and the second drying plate 8 are conveniently fixed to the first placement slot 3 and the second placement slot 6 on the top of the drying rack 2, thereby adsorbing and collecting water vapor in the reagent kit body 1.
[0029] Preferably, two sets of insert rods 10 are symmetrically distributed at the bottom of the top frame 11, and the shape and size of the insert rods 10 are adapted to the slots 9.
[0030] In practical use, the silicone insert 10 is snapped into the slot 9, thereby fixing the top frame 11 at the top of the slot 9. This allows the top drying plate 12 on the top frame 11 to absorb and collect the surrounding moisture, thus providing moisture protection for the reagent tubes placed on the reagent rack 20.
[0031] Preferably, the top surface of the top frame 11 is connected to the limiting rod 15, the surface of the limiting rod 15 is engaged with the groove surface on one side of the baffle 13, the bottom surface of the top frame 11 abuts against the sealing cover 16, and the inner wall surface of the sealing cover 16 is provided with a limiting groove 17.
[0032] In practical use, when the top drying plate 12 becomes damp and discolored and needs to be replaced, pull the baffle 13 in the opposite direction to the groove on the surface of the baffle 13, so that it rotates through the rotating shaft 14 connected on one side, thereby disengaging it from the rubber limiting rod 15, and thus replacing the top drying plate 12 placed on the top frame 11.
[0033] Preferably, the limiting groove 17 is engaged with the protrusion on the surface of the reagent chamber 18, the inner wall surface of the reagent chamber 18 is fitted with a foam pad 19, and the surface of the reagent chamber 18 is connected to the surface of the reagent rack 20.
[0034] In practical use, pull up the sealing cap 16 that is engaged with the limiting groove 17 to expose the opening end of the reagent chamber 18 at the bottom and the foam pad 19. Place the reagent bottle containing the sample into the foam pad 19. The foam pad 19 is made of moisture-proof foam material, which can reduce the external air circulation.
[0035] Preferably, a slot 21 is formed longitudinally on the surface of the reagent rack 20, the surface of the slot 21 is engaged with the surface of the dovetail block 22, and the bottom surface of the dovetail block 22 is connected to the bottom of the inner wall of the reagent kit body 1.
[0036] In practical use, the reagent rack 20 can be fixed to the dovetail block 22 by engaging with the slots 21 on both sides of the surface.
[0037] Preferably, the slot 21 is a trapezoidal through slot with symmetrical circular grooves on its surface, and the shape and size of the circular grooves are adapted to the circular rubber block at the upper end of the dovetail block 22.
[0038] In practical use, the circular rubber protrusions on the surface of the dovetail block 22 facilitate the engagement and fixation of the connection between the two when it is inserted into the slot 21, thereby fixing the position of the reagent holder 20 in the reagent kit body 1.
[0039] Working principle: After placing the human gene diagnostic test sample in the reagent kit body 1, the sample is stored in a dedicated reagent bottle. Then, the top cover of the reagent kit body 1 is opened, and the top frame 11 is lifted upward by pulling the grooves on both sides, causing the bottom-connected insert 10 to disengage from the interlocking slot 9. This removes the top frame 11 placed on top of the opening of the reagent kit body 1, exposing the reagent holder 20 and sealing cap 16 at the bottom. The sealing cap 16, which is engaged with the limiting groove 17, is pulled upward, exposing the opening of the bottom reagent chamber 18 and the foam pad 19. The reagent bottle containing the sample is placed inside the foam pad 19, which is made of moisture-proof foam material to reduce external air circulation. Meanwhile, the reagent rack 20 is made of high-density plastic board, which can be used to separate the reagent bottles by using the multiple sets of reagent chambers 18 connected to it, so as to avoid the reagent bottles being damaged by collision during transportation. Then, the above operation is repeated to snap the sealing cap 16 onto the protrusion on the surface of the reagent chamber 18, so that the rubber gasket on the inner wall of the sealing cap 16 abuts against the top of the reagent bottle. At the same time, the reagent rack 20 can be snapped and fixed on the dovetail block 22 by the slots 21 opened on both sides of the surface to fix the position of the reagent rack 20.
[0040] Furthermore, the first drying plate 5 and the second drying plate 8, which are inserted into the mesh drying rack 2, are made of silica gel with a non-woven fabric covering their surface. The first drying plate 5 and the second drying plate 8 contain silica gel desiccant (color-changing type) – blue when anhydrous and pink after absorbing moisture. This not only absorbs internal moisture but also provides a visual indication of whether the reagent tubes have become damp. This allows for easy observation of whether the first drying plate 5 and the second drying plate 8 need to be replaced during repeated transfers of reagent tubes into the reagent chamber 18, preventing any impact on the moisture absorption and protection effect. After placing the reagent bottle, the insert rod 10 can be re-inserted into the slot 9 to cover the opening of the reagent kit body 1, preventing moisture from eroding the bottom reagent chamber 18 from the top opening. The reagent tubes inside, and the top drying plate 12 is also made of silica gel desiccant. When it becomes damp and discolored and needs to be replaced, pull the baffle 13 in the opposite direction to the groove on the surface of the baffle 13, so that it can be rotated by the rotating shaft 14 connected on one side, thereby disengaging it from the rubber limiting rod 15, so that the top drying plate 12 placed on the top frame 11 can be replaced. The inner wall of the drying rack 2 and the groove at the bottom of the top frame 11 are provided with a mesh structure, which facilitates the adsorption and collection of water vapor on the surface of the reagent rack 20 by the first drying plate 5, the second drying plate 8 and the top drying plate 12. The surface of the reagent kit body 1 is covered with a layer of aluminum foil film, which uses the water impermeability of aluminum foil to block the penetration of external moisture.
