Description

Technical Field

[0001] This utility model relates to the field of sample detection pretreatment technology, and in particular to a rapid detection pretreatment kit for trace samples. Background Technology

[0002] In the field of trace sample detection, the extremely small sample volume often makes effective pretreatment and detection difficult. Traditional sample pretreatment methods are often cumbersome and prone to sample damage or contamination, thus affecting the accuracy and efficiency of detection. Furthermore, the storage and transportation of trace samples present a significant challenge, requiring assurance of sample integrity and stability during storage and transport.

[0003] Chinese Patent CN216192267U discloses a sample processing structure suitable for card holders. This invention divides the sample chamber into a sample addition chamber and a sample processing chamber connected by a siphon bend, and provides an air extraction channel at the top of the sample processing chamber. Due to the siphon effect, the sample initially remains in the siphon bend and does not automatically enter the sample processing chamber. At the start of the test, air is extracted from the siphon bend into the sample processing chamber, effectively preventing the sample from seeping into other reaction chambers before the test begins, thus avoiding interference with subsequent testing steps and inaccurate results.

[0004] However, in the process of sample storage and preprocessing, the lack of effective fixation and convenient operation methods leads to problems such as sample damage and low preprocessing efficiency. In view of this, a rapid detection preprocessing kit for trace samples is provided. Summary of the Invention

[0009] Furthermore, two mounting plates are fixedly installed on the partition and the inner wall of the box near the placement area. Each mounting plate has an elongated groove. Connecting plates are fixedly connected to both sides of the placement plate. The connecting plates are inserted into the elongated grooves. A baffle for limiting the position of the connecting plates is slidably installed through the elongated grooves in the mounting plates.

[0010] Furthermore, a circular tube is fixedly connected to the bottom of the sealing cap. The outer diameter of the circular tube is smaller than the inner diameter of the liquid inlet. Several slots are arranged in a ring array at the lower end of the circular tube.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figures 1-8 As shown, the purpose of this embodiment is to provide a rapid detection pretreatment box for trace samples, including a box body 1. A partition 11 is fixedly installed inside the box body 1, dividing the box body 1 into a placement area 12 and a processing area 13. Two placement plates 2 are inserted into the placement area 12. Several slots 21 are opened on the placement plates 2, and several sample tubes 3 are inserted into the slots 21. Limiting plates 26 for fixing the sample tubes 3 are symmetrically slidably arranged on both sides of the placement plates 2 near each slot 21. A processing box 4 is provided in the processing area 13. A liquid inlet is opened on the processing box 4, and a sealing cap 5 is inserted into the liquid inlet. Fixing plates 6 for fixing the processing box 4 are hinged to both the partition 11 and the side wall of the inner wall of the box body 1 near the processing area 13.

[0031] A flexible layer is provided at the lower end of the slot 21. When the sample tube 3 is fully inserted into the slot 21, the flexible layer can effectively cushion and protect the lower end of the sample tube 3, preventing damage or scratches caused by hard impact. The placement plate 2 has symmetrically formed grooves 25 on both sides near each slot 21. The limiting plate 26 is slidably installed in the groove 25, and several springs 27 are provided in the groove 25. One end of each spring 27 is fixedly connected to the inner wall of the groove 25, and the other end of each spring 27 is connected to the limiting plate 26. The side walls are fixedly connected, so under the elastic force of the spring 27, the two limiting plates 26 can tightly clamp the sample tube 3, preventing the sample tube 3 from shaking and being damaged in the slot 21 when a sample tube 3 smaller than the diameter of the slot 21 is inserted; and in order to prevent the limiting plate 26 from detaching from the slide groove 25, protrusions are fixedly connected to both sides of the limiting plate 26, and the placement plate 2 is provided with limiting grooves that match the protrusions. The protrusions slide in them, so that the limiting plate 26 can be effectively constrained and guided when sliding.

[0032] The limiting plate 26 is arc-shaped, which fits more closely to the outer wall of the sample tube 3. Several elastic layers 261 are fixedly connected to the side wall of the limiting plate 26 near the slot 21. The elastic layers 261 are made of silicone or rubber and are used to buffer the clamping force to prevent the limiting plate 26 from clamping the sample tube 3 and causing wear or even damage to its surface. In order to facilitate users to clearly understand the type of trace reagent in each sample tube 3, a slot 23 is provided on the placement plate 2 in front of each slot 21. A label plate 24 is attached in the slot 23. Users can clearly mark the type of reagent, number and other key information in each sample tube 3 on the label plate 24.

[0033] Two mounting plates 15 are fixedly installed on the inner walls of the partition 11 and the box body 1 near the placement area 12. Each mounting plate 15 has a long groove 151. Connecting plates 22 are fixedly connected to both sides of the placement plate 2. The connecting plates 22 are inserted into the long grooves 151. A baffle 152 for limiting the position of the connecting plate 22 is slidably installed through the long grooves 151 in the mounting plate 15. A baffle groove is provided on the mounting plate 15, and the baffle 152 slides in the baffle groove. When installing the placement plate 2, the baffle 152 is slid upward to make room for the insertion of the connecting plate 22. Then, the connecting plate 22 is inserted into the long groove 151 until it is inserted into the end of the long groove 151. At this time, the baffle 152 is released, and it slides down along the baffle groove under the action of gravity to block the outlet of the long groove 151, so as to prevent the connecting plate 22 from slipping off the mounting plate 15 and causing the placement plate 2 and the sample tubes 3 on it to fall off. The cross section of the placement plate 2 is a rhombus with an inclined setting, that is, the upper surface of the placement plate 2 is inclined, so that the user can easily view the information on the label plate 24 and smoothly take out the required sample tubes 3. The mounting plate 15 is also a rhombus plate with an inclined setting.

[0034] A circular tube 51 is fixedly connected to the bottom of the sealing cap 5. The outer diameter of the circular tube 51 is smaller than the inner diameter of the liquid inlet. Several slots 511 are arranged in a ring at the lower end of the circular tube 51. Several stirring blades 512 are fixedly connected in a ring on the outer wall of the lower end of the circular tube 51. Each stirring blade 512 is located between two adjacent slots 511, and the length of the stirring blade 512 is less than the distance between the outer wall of the circular tube 51 and the inner wall of the liquid inlet, so as not to affect the insertion of the sealing cap 5 into the liquid inlet. In use, the sample tube 3 is taken out and the trace reagent inside is poured into the processing box 4 through the liquid inlet. Then the sealing cap 5 is inserted into the liquid inlet. The sealing cap 5 can be rotated as needed. At this time, the stirring blades 512 at the lower end of the circular tube 51 will rotate in the reagent, effectively stirring and mixing the reagent, thereby promoting the detection efficiency. At the same time, the setting of the slots 511 ensures the smooth flow of the reagent during the stirring process and avoids the resistance caused by stirring.

[0035] A fixed frame 14 is fixedly installed in the processing area 13, and the processing box 4 is inserted into the fixed frame 14 to prevent the processing box 4 from detaching from the processing area 13 in the horizontal direction. The partition 11 and the inner wall of the box body 1 are provided with interconnected grooves 16 and square grooves 17 on the side wall near the processing area 13.

[0036] A fixing shaft 61 is provided through one end of the fixing plate 6. One end of the fixing plate 6 is rotatably mounted on the fixing shaft 61, and both ends of the fixing shaft 61 are fixedly mounted on both ends of the groove 16. Nuts 62 are also threaded onto the fixing shaft 61. In the initial state, the fixing plate 6 is completely set in the square groove 17. The processing box 4 is inserted into the fixing frame 14. Then, the fixing plate 6 is rotated so that one end of it rotates around the fixing shaft 61 until the fixing plate 6 is in contact with the upper surface of the processing box 4. Then, the nut 62 is tightened, and one side of the fixing plate 6 is gradually pushed towards one side wall of the groove 16, thereby achieving a stable fixation of the fixing plate 6. After both sides of the fixing plate 6 are fixed in accordance with the above steps, the processing box 4 is effectively fixed in the processing area 13. Even in the vertical direction, it can prevent the processing box 4 from accidentally falling off during the transport of the box body 1.

[0037] In practical use, the sample tubes 3 containing trace amounts of reagent are inserted one by one into the slots 21 on the placement plate 2. The limiting plate 26, under the elastic force of the spring 27, tightly clamps the sample tubes 3. A label plate 24 corresponding to the sample tube 3 is inserted into the slot 21. The box 1 is opened, and the baffle 152 on the mounting plate 15 is slid upwards to make room for the insertion of the connecting plate 22. The connecting plates 22 on both sides of the placement plate 2 are inserted into the long grooves 151 of the mounting plate 15 until they are fully inserted into the end of the long groove 151. The baffle 152 is then released, allowing it to slide downwards along the baffle groove under gravity, thereby blocking the outlet of the long groove 151. Place the fixed plate 2, insert the processing box 4 into the fixed frame 14, rotate the fixed plate 6 so that one end of it rotates around the fixed shaft 61 until the fixed plate 6 is in contact with the upper surface of the processing box 4, tighten the nut 62, and gradually push one side of the fixed plate 6 towards the side wall of the groove 16 to achieve a stable fixation of the fixed plate 6; take out the required sample tube 3 from the placement plate 2, pour the trace reagent in the sample tube 3 into the processing box 4 through the liquid inlet, insert the sealing cap 5 into the liquid inlet, and rotate the sealing cap 5 as needed. Use the stirring blade 512 at the lower end of the round tube 51 to rotate in the reagent to effectively stir and mix the reagent, and complete the pretreatment of the reagent in the processing box 4.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
