Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0020] like Figures 1 to 6As shown, a collection tube with a filtering function in one embodiment of this utility model includes a placement box 1. Multiple opposing first placement slots 10 are provided on the top of the placement box 1. Each first placement slot 10 has a limiting structure inside. A tube body 5 is placed inside each first placement slot 10. A cap 6 is installed at the top of each tube body 5. Four locking slots are provided on the outside of each tube body 5. A sealing strip 11 is connected inside each locking slot. A locking strip 17 is engaged inside each locking slot, and each locking strip 17 contacts the sealing strip 11. Each set... Each of the clips 17 is connected to a filter screen 12, and each filter screen 12 is located inside the tube body 5. By setting the filter screen 12 connected by the clips 17 inside the tube body 5, the collected samples, such as feces and secretions containing large particulate impurities, can be directly filtered in situ, effectively intercepting solid impurities. The filter screen 12 is snapped into the slot on the outside of the tube body 5 by the clips 17, so as to achieve quick disassembly and assembly. When it is necessary to replace the filter screen 12 with a different pore size to adapt to the coarse filtration and fine filtration needs, or to clean or test the filter screen 12 separately, it is not necessary to replace the entire tube body 5, thus reducing the cost of use.

[0021] Each limiting structure includes a limiting groove 14 formed inside the first placement groove 10. Each limiting groove 14 is provided with a limiting block 13. Each set of limiting blocks 13 is in contact with the tube body 5. Each limiting groove 14 is connected with a spring 15 and a telescopic rod 16. Each spring 15 is sleeved on the outside of the telescopic rod 16. One end of each set of spring 15 and telescopic rod 16 is connected to the limiting block 13. The spring 15 in the limiting groove 14 cooperates with the telescopic rod 16 to push the limiting block 13 to automatically fit against the outer wall of the tube body 5.

[0022] The outer side of the placement box 1 has two mounting slots 3, and the inner wall of each mounting slot 3 has two slide rails 2. The inner side of the placement box 1 has two sliding grooves, and the two sliding grooves are slidably connected to a sliding plate 4. When it is necessary to change the classification label of the placement box 1, such as the sample type or collection batch label, the operator only needs to pull the placement box 1 out of the external device along the slide rail 2. The label can be easily replaced without disassembling the entire structure. After replacement, it can be pushed back and fixed along the slide rail 2. No additional tools are required, which improves the efficiency of label replacement.

[0023] Multiple opposing second placement slots 8 are provided above the slide plate 4. Each second placement slot 8 corresponds to the first placement slot 10. One end of each tube 5 passes through the second placement slot 8 and extends to the outside of the second placement slot 8. A protective sleeve 9 is installed inside each second placement slot 8. Each protective sleeve 9 is in contact with the tube 5. Multiple protective pads 7 are installed inside the placement box 1. The bottom end of each tube 5 is placed inside the protective pad 7. The flexible protective sleeve 9 inside the second placement slot 8 can prevent the tube 5 from directly rubbing against the hard inner wall of the placement slot, reduce scratches and wear on the outer wall of the tube 5 and extend its service life. At the same time, its flexible properties can enhance the clamping force on the tube 5. The auxiliary limiting structure further improves the stability of the tube 5. The protective pad 7 at the bottom of the tube 5 can buffer the impact when the tube 5 is put into the placement box 1 to prevent the tube 5 from falling and breaking at the bottom.

[0024] Working principle: First, the filter screen 12 is aligned with the four slots on the outside of the tube body 5 and secured by the edge clips 17, ensuring the filter screen 12 is stably placed inside the tube body 5. Simultaneously, the sealing strip 11 inside the slots makes tight contact with the clips 17, filling gaps and forming a seal to prevent subsequent samples from circling the filter screen 12, thus ensuring effective filtration. Next, the cap 6 at the top of the tube body 5 is opened, and the sample to be collected, such as feces or secretions containing large particles, is injected into the tube body 5. As the sample flows through the filter screen 12, its pores intercept solid impurities. To prevent interference from flocculent matter and other contaminants, only liquid samples that meet the testing requirements are allowed to enter the lower part of the tube 5. After collection, the cap 6 is placed on the tube to seal the opening and prevent sample evaporation, contamination, or leakage. Finally, the tube 5 is stored and fixed: the tube 5 containing the sample is placed in the first placement slot 10 of the placement box 1. The limiting structure inside the slot restricts the shaking of the tube 5 by contacting it. Multiple sets of first placement slots 10 can centrally store multiple tubes 5, avoiding loss or collision caused by scattered storage, and facilitating unified sample management and subsequent transportation and laboratory processing.
