Description

Technical Field

[0001] The utility model relates to the technical field of nucleic acid detection equipment, and in particular to an integrated nucleic acid detection card box and nucleic acid detection equipment. Background Art

[0002] Currently, most tests for molecular diagnosis, morphology, immunology, etc. are carried out in professional laboratories. The traditional detection process generally includes the following steps: first, nucleic acid amplification is performed in large and medium-sized detection equipment; then the amplified nucleic acid is manually transferred to the electrophoresis detection equipment for electrophoresis detection; finally, the electrophoresis detection results are manually transferred to a dedicated fluorescence analyzer for result analysis.

[0003] After searching, announcement number CN218290922U discloses an integrated nucleic acid detection card box and nucleic acid detection equipment, which relates to the technical field of nucleic acid detection equipment, including a nucleic acid detection card box body and a waste liquid bin, a waste liquid box, a second pipe, a first pipe, a first sealing rubber, and a sealing mechanism. The utility model sets a sealing mechanism and an auxiliary mechanism. When the waste liquid box is fully installed inside the waste liquid bin, the fixation between the rotating shaft and the connecting seat is released by the auxiliary mechanism, and the torsion spring drives the cover plate to rotate through the rotating shaft, so that the cover plate is pressed against the outer wall of the first pipe, and the waste liquid box is pulled out of the waste liquid bin. When the first pipe is separated from the second pipe, the torsion spring drives the cover plate to reset through the rotating shaft, so that the cover plate rotates to one end of the second pipe, so that the second sealing rubber is inserted into the second pipe, and the rotating shaft and the connecting seat are fixed by the auxiliary mechanism, so as to facilitate the staff to directly put the waste liquid into the waste liquid bin. The function of transferring the waste liquid inside the liquid box to a designated location for treatment makes it convenient for the staff to operate; its defect is that when the waste liquid box in this scheme is connected to the waste liquid bin, the waste liquid box is limited only by the outer side of the waste liquid box fitting with the inner side of the waste liquid bin. When the main body of the nucleic acid detection card box is tilted, the waste liquid box is easy to slide out from the inside of the waste liquid bin, affecting the collection of the waste liquid. Therefore, it is particularly important to improve the existing detection card box and design a new integrated nucleic acid detection card box and nucleic acid detection equipment to solve the above-mentioned technical defects and improve the practicability of the overall detection card box.

[0031] The limiting component 5 is used to increase the stability of the connection between the waste liquid box 4 and the waste liquid bin 3;

[0032] Furthermore, the limiting assembly 5 is composed of a fixed frame 8, a limiting rod 9, a moving block 10, an arc groove 11, a rotating rod 12, a sliding block 13 and a connecting rod 14. The fixed frame 8 is located inside the waste liquid bin 3 and outside the waste liquid box 4. Two groups of limiting rods 9 are both located inside the fixed frame 8 and close to one end of the waste liquid box 4. The moving block 10 is slidably connected to the inside of the fixed frame 8 and is located between the two groups of limiting rods 9. Multiple groups of arc grooves 11 are all opened on the outside of the fixed frame 8. Two groups of rotating rods 12 are rotatably connected to one end of the moving block 10 away from the limiting rod 9. The sliding block 13 is rotatably connected to one end of the rotating rod 12 away from the moving block 10. The connecting rod 14 is located inside the two groups of sliding blocks 13. When the waste liquid box 4 is connected to the waste liquid bin 3, the limiting assembly 5 can increase the stability of the connection between the waste liquid box 4 and the waste liquid bin 3. When the card box body 1 is tilted, the waste liquid box 4 is prevented from slipping from the inside of the waste liquid bin 3, affecting the collection of waste liquid.

[0033] Among them, a guide groove 15 is opened on the outer side of the arc groove 11, and the limit rod 9 extends to the arc groove 11 and the guide groove 15.

When the moving block 10 is displaced, the protrusion can be displaced through the groove, driving the limiting rod 9 to be displaced.

[0035] Furthermore, the sliding block 13 and the connecting rod 14 are slidably connected. Compression springs 17 are provided at both ends of the connecting rod 14 and on the outside of the two groups of sliding blocks 13.

[0037] The closing component 7 is used to close the connecting pipe 6;

[0038] Furthermore, the closing component 7 is composed of a rotating disk 19, a driving rod 20, an engaging groove 21, a closing plate 22 and an engaging strip 23. The rotating disk 19 is rotatably connected to the top of the connecting tube 6, the driving rod 20 is rotatably connected to the top of the connecting tube 6 and is located on the outside of the rotating disk 19, the engaging groove 21 is opened at the end of the driving rod 20 away from the rotating disk 19, the closing plate 22 is fixedly connected to the bottom of the rotating disk 19 and is located inside the connecting tube 6, the engaging strip 23 is fixedly connected to the inside of the waste liquid bin 3 and close to one end of the driving rod 20. When the waste liquid box 4 is moved out from the inner position of the waste liquid bin 3, the connecting tube 6 can be closed and sealed by the closing component 7, so that the waste liquid in the waste liquid box 4 can be transferred to the designated position for treatment, which is convenient for the staff to operate.

[0039] Furthermore, a driving groove 24 is opened at one end of the driving rod 20 close to the rotating disk 19, and the rotating disk 19 extends to the inside of the driving groove 24 and is fixedly connected with a fixing rod 25, and the rotating disk 19 is connected to the driving groove 24 through the fixing rod 25, and the meshing groove 21 and the meshing bar 23 are meshingly connected. When the waste liquid box 4 moves out of the interior of the waste liquid bin 3, the connecting tube 6 is driven to move, so that the driving rod 20 can be moved. The meshing connection between the meshing groove 21 and the meshing bar 23 enables the driving rod 20 to rotate through the meshing bar 23, and cooperates with the fixing rod 25 extending to the inside of the driving groove 24 to drive the rotating disk 19 to rotate, so that the closing plate 22 can rotate, and the interior of the connecting tube 6 is closed and sealed.

[0040] When the hopper 10 is in a state of being moved, the hopper 10 is moved in a direction of rotation to move the hopper 10 in a direction of rotation, so that the hopper 10 can move freely, and the hopper 10 can move freely. When the waste liquid box 4 needs to be taken out from the interior of the waste liquid bin 3, the waste liquid box 4 is slightly displaced, the limiting rod 9 is squeezed, and the sliding block 13 is driven to displace by the compression spring 17, so that the rotating rod 12 can be displaced, and the moving block 10 is driven to be displaced, and the moving block 10 is reset so that the limiting rod 9 can be opened and closed, thereby the waste liquid box 4 can be moved out of the interior of the waste liquid bin 3. When the waste liquid box 4 is moved out of the interior of the waste liquid bin 3, the connecting tube 6 is driven to be displaced, so that the driving rod 20 can be displaced, and the meshing groove 21 is meshed with the meshing strip 23. The driving rod 20 can be rotated through the meshing strip 23, and the fixed rod 25 extending to the inside of the driving groove 24 drives the rotating disk 19 to rotate, so that the closing plate 22 can rotate, and the interior of the connecting tube 6 is closed and sealed. Compared with the existing detection cartridge, the utility model can improve the overall practicality of the detection cartridge through design.
