[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figure 1As shown in the figure, an embodiment of the present invention provides a collection component, which includes a collection member 10 and a mixing member 20. Among them, the collection member 10 is provided with a conduction structure, and the collection member 10 is used to collect samples. Specifically, the mixing member 20 has an independently arranged mixing cavity and a preservation liquid cavity 21. The mixing cavity is used to mix the sample and the preservation liquid, and the preservation liquid cavity 21 is used to store the preservation liquid. Among them, the collection member 10 has an avoidance position and a conduction position relative to the mixing member 20. When the collection member 10 is in the avoidance position, the preservation liquid cavity 21 is in a sealed state, and the preservation liquid will not spill out of the preservation liquid cavity 21; when the collection member 10 is in the conduction position, the conduction structure can conduct the preservation liquid cavity 21 and the mixing cavity, so as to conduct the preservation liquid in the preservation liquid cavity 21 into the mixing cavity. At this time, the sample can be mixed with the preservation liquid in the mixing cavity.

[0038] Specifically, the user can use the collection member 10 to collect fecal samples. During the process of collecting samples, the collection member 10 is in the avoidance position. At this time, the preservation liquid cavity 21 is in a sealed state, and the preservation liquid will not spill out of the preservation liquid cavity 21. The user will not come into contact with the preservation liquid, so the safety of using the device can be improved. After the user completes the collection of the sample using the collection member 10, by moving the collection member 10 to the conduction position, the conduction structure on the collection member 10 can conduct the preservation liquid cavity 21 and the mixing cavity at this time. The preservation liquid can directly enter the preservation liquid cavity 21 of the mixing member 20 from the preservation liquid cavity 21, and the problem of the preservation liquid spilling will not occur. With the above structure, only by moving the collection member 10 from the avoidance position to the conduction position, the process of loading the collection member 10 into the mixing member 20 and the combination of the preservation liquid and the sample can be completed at the same time, so that the collection steps can be simplified, and the collection efficiency can be improved.

[0039] Among them, the preservation liquid cavity 21 of the mixing member 20 can be integrally formed with the mixing member, or an independent component can be provided, and the preservation liquid cavity 21 is provided in the independent component. In this embodiment, the mixing member 20 has an independently arranged component, and the preservation liquid cavity 21 is provided in the component.

[0040] Applying the collection component provided in this embodiment, by making the mixing member 20 have an independently arranged mixing cavity and a preservation liquid cavity 21, after the sample is collected using the collection member 10, only by moving the collection member 10 to the conduction position, the conduction structure on the collection member 10 can conduct the preservation liquid cavity 21 and the mixing cavity, so that the preservation liquid in the preservation liquid cavity 21 can flow into the mixing cavity, so that the sample and the preservation liquid can be mixed in the mixing cavity. Through the above device, the staff does not need to inject the preservation liquid into the mixing member additionally, which can simplify the collection steps, and then improve the collection efficiency, and there is no risk of spilling during the inflow of the preservation liquid, ensuring the normal mixing of the sample.

[0041] In this embodiment, the mixing member 20 includes a mixing tube 22 and a preservation liquid tube 23 that are connected to each other. The preservation liquid tube 23 has a preservation liquid cavity 21, and the mixing tube 22 has a mixing cavity. Among them, the preservation liquid tube 23 can be arranged at one end of the mixing tube 22, or the preservation liquid tube 23 can be directly arranged inside the mixing tube 22. In this embodiment, the preservation liquid tube 23 is arranged inside the mixing tube 22. In this way, after the conduction structure on the collection member 10 conducts the preservation liquid cavity 21 and the mixing cavity, since the preservation liquid cavity 21 is located inside the mixing cavity, the preservation liquid can directly enter the mixing cavity, thereby solving the problem that the preservation liquid is easily spilled.

[0042] In other embodiments, by using an integrally formed method, a preservation liquid cavity 21 and a mixing cavity can be simultaneously arranged in the mixing tube 22. In this way, the preservation liquid tube 23 can be not separately arranged, thereby simplifying the structure of the device and reducing the processing cost.

[0043] As Figure 3 shown, the preservation liquid tube 23 is a double-layer tube wall structure. The preservation liquid tube 23 has an inner layer 231 and an outer layer 232 that are oppositely arranged, and there is a gap between the inner layer 231 and the outer layer 232, and the gap forms the preservation liquid cavity 21. Specifically, the collection member 10 can pass through the inner layer 231 and enter the mixing cavity of the mixing tube 22. With the above structure, the preservation liquid can be stored by the preservation liquid tube 23, and the preservation liquid tube 23 will not block the collection member 10. In this embodiment, the preservation liquid tube 23 is a ring-shaped columnar structure. In other embodiments, the preservation liquid tube 23 can be a semi-circular columnar, crescent columnar or other structures.

[0044] In this embodiment, the preservation liquid cavity 21 has a first end and a second end that are oppositely arranged. Among them, the first end of the preservation liquid cavity 21 is arranged close to the collection member 10, and the first end of the preservation liquid cavity 21 is a closed structure, and the preservation liquid will not spill out from the first end of the preservation liquid cavity 21. And, the second end of the preservation liquid cavity 21 is an open structure, and the preservation liquid cavity 21 can be conducted with the mixing cavity through the open structure. Since the second end of the preservation liquid cavity 21 is arranged towards the inside of the mixing tube 22, it is convenient for the preservation liquid to flow from the preservation liquid cavity 21 into the mixing cavity.

[0045] Among them, the mixing member 20 further includes a plugging assembly 24. The plugging assembly 24 is arranged at the open structure of the preservation liquid cavity 21, and the plugging assembly 24 is used to seal the preservation liquid cavity 21. Specifically, the plugging assembly 24 has a plugging state and an open state. When the collection member 10 moves from the avoidance position to the conduction position, the conduction structure cooperates with the plugging assembly 24 to switch the plugging assembly 24 from the plugging state to the open state. At this time, the preservation liquid cavity 21 is conducted with the mixing cavity. Among them, the plugging assembly 24 includes a sealing member, a valve, etc., as long as the plugging assembly 24 can plug the open structure and switch from the plugging state to the open state.

[0046] In this embodiment, the plugging assembly 24 includes a seal 241 and a connecting member 242. Among them, both the seal 241 and the connecting member 242 are provided at the second end of the preservation liquid chamber 21. The seal 241 seals the opening structure through the connecting member 242. The shape of the seal 241 matches the opening structure of the preservation liquid chamber 21. The connecting member 242 has a first plugging position and a first opening position which are oppositely arranged. When the collecting member 10 is in the avoidance position, the connecting member 242 is in the first plugging position. At this time, the preservation liquid chamber 21 is plugged by the seal 241 into a closed structure. Specifically, the conduction structure is used to drive the connecting member 242 to move from the first plugging position to the first opening position. When the collecting member 10 moves to the conduction position, the connecting member 242 is in the first opening position. At this time, the preservation liquid chamber 21 communicates with the mixing chamber.

[0047] Specifically, the connecting member 242 is clamped on the inner layer 231, and the seal 241 is an annular structure. By connecting the outer edge of the seal 241 to the end face of the outer layer 232 and connecting the inner edge of the seal 241 to the end face of the inner layer 231 through the connecting member 242, the seal 241 can be fixed at the second end of the preservation liquid chamber 21, and the preservation liquid chamber 21 is plugged by the seal 241. In this embodiment, the seal 241 includes a sealing film. A clamping boss is provided on the inner wall of the inner layer 231. During the process of assembling the connecting member 242 into the inner layer 231, the clamping boss can limit the displacement of the connecting member 242. When the connecting member 242 is assembled in place and abuts against the clamping boss, that is, the connecting member 242 is in the first plugging position, the end of the connecting member 242 is flush with the end face of the second end of the preservation liquid chamber 21. At this time, fixing the sealing film at the second end of the preservation liquid chamber 21 can complete the plugging of the preservation liquid chamber 21. When the conduction structure drives the connecting member 242 to move from the first plugging position to the first opening position, the connecting member 242 is in the first opening position. At this time, the preservation liquid chamber 21 communicates with the mixing chamber. Among them, the seal 241 includes a transparent film or a film of other materials. The sealing method can be selected as heat sealing or other methods according to the production process and usage requirements.

[0048] In this embodiment, the mixing tube 22 includes a first section and a second section connected to each other. The first section of the mixing tube 22 is disposed close to the collection member 10. The cross-sectional dimension of the first section of the mixing tube 22 is larger than that of the second section of the mixing tube 22. The preservation liquid tube 23 is located within the first section of the mixing tube 22. With the above structure, the first section of the mixing tube 22 can be used to accommodate the preservation liquid tube 23, which can reduce the volume of the device. Moreover, after the preservation liquid tube 23 is assembled into the first section of the mixing tube 22, the end of the preservation liquid tube 23 will abut against the second section of the mixing tube 22. The second section of the mixing tube 22 can be used to limit the preservation liquid tube 23 to fix the preservation liquid tube 23 and prevent the preservation liquid tube 23 from entering the mixing tube 22 excessively. Furthermore, by making the cross-sectional dimension of the first section of the mixing tube 22 larger than that of the second section of the mixing tube 22, on the one hand, it is convenient for the collection member 10 with the fecal sample to extend into the mixing tube 22, avoiding the fecal sample from touching the tube opening or the user's hand and improving the user's collection experience; on the other hand, it is for placing the preservation liquid tube.

[0049] Among them, the collection member 10 includes a main body 11, a solid collection part 12, and a suction / discharge member 13. Among them, the main body 11 has a holding end and a collection end disposed opposite to each other. The conduction structure is provided on the main body 11, and a collection hole is provided at the collection end. By disposing the solid collection part 12 at the collection end, the solid collection part 12 can be used to collect solid samples. By disposing the suction / discharge member 13 at the holding end and connecting the suction / discharge member 13 to the collection hole, the suction / discharge member 13 can suck or discharge liquid samples through the collection hole. With the above structure, the collection member 10 is suitable for both quantitatively collecting solid feces and quantitatively collecting liquid feces, which can improve the collection efficiency and meet the fecal collection requirements. By adjusting the sizes of the solid collection part 12 and the suction / discharge member 13, quantitative sampling can be achieved. In this embodiment, the suction / discharge member 13 includes a silica gel suction head. Specifically, the silica gel suction head is a cavity structure with a hollow interior. The volume of the hollow cavity can be determined or adjusted according to the volume of the sample to be collected, and the solid collection part 12 is used to achieve quantitative collection of the sample.

[0050] Among them, the quantitative collection member can be the above-mentioned integrated dry-wet dual-purpose collection member, or can be designed as two collection members with dry-wet separation. The size of the silica gel head can be adjusted according to the reagent demand, and scale marks or printing can be made on the main body as required.

[0051] In the prior art, the Bristol Stool Scale is a medical classification method for feces, which classifies feces into 7 categories according to their morphology, namely: Type 1: Separate hard lumps (difficult to pass); Type 2: Sausage-shaped, but with a bumpy surface; Type 3: Sausage-shaped, but with cracks on the surface; Type 4: Like a sausage or a snake, and the surface is very smooth; Type 5: Soft lumps with smooth edges (easy to pass); Type 6: Coarse-edged, fluffy lumps, pasty feces; Type 7: Watery, without solid lumps (completely liquid).

[0052] In this embodiment, there is a hollow structure with a certain aperture in the center of the main body 11 for collecting the seventh type of watery feces. The solid collection part 12 is a wheel-shaped fan blade structure in the clockwise direction on all four sides. The edge of the fan blade structure is relatively thin. The height of the solid collection part 12 and the width of the fan blades can achieve the quantification of the fecal sample. Among them, there are parallel small holes on two opposite wheel-shaped fan blade structures, and these small holes are supplemented with homogenization operations. In this embodiment, there is a 2-mm through hole in the center of the main body 11.

[0053] Moreover, the design that the outer periphery of the fan blade is relatively thin or sharp plays an important role in whether the collection piece can collect the fecal sample. The opening direction, angle, number of fan blades, fan blade opening, shape, aperture, number of holes on the fan blade, height of the fan blade, etc. can all be adjusted accordingly according to the actual sampling requirements.

[0054] If samples of types 1-6 are collected, after the samples fill the gaps of the solid collection part 12, the quantitative collection of the samples is completed; if samples of type 7 are collected, by squeezing the silicone head with a certain space at the top, the samples can enter the hollow structure of the main body 11 through the solid collection part 12 due to the pressure difference, realizing the quantitative collection of the watery samples.

[0055] Specifically, a conduction piece 111 is arranged on the side wall of the main body 11. The extending direction of the conduction piece 111 is the same as the axial direction of the main body 11, and the conduction piece 111 forms a conduction structure. By arranging the conduction piece 111 on the side wall of the main body 11, when the collection piece 10 is inserted into the mixing tube 22, when the collection piece 10 moves to the conduction position, the conduction piece 111 will abut against the connecting piece 242 and drive the connecting piece 242 to move to the first open position, so that the preservation liquid cavity 21 is communicated with the mixing cavity.

[0056] In this embodiment, a plurality of conduction pieces 111 are arranged on the side wall of the main body 11, and the plurality of conduction pieces 111 are arranged at intervals along the circumferential direction of the main body 11. Moreover, the end of the conduction piece 111 away from the suction and discharge part 13 is an arc structure, which is convenient for the conduction piece 111 to drive the connecting piece 242 to move. In this embodiment, four conduction pieces 111 are arranged on the side wall of the main body 11.

[0057] To seal the collection component, the collection piece 10 further includes a collection head cover 14, and the collection head cover 14 is detachably connected to one end of the mixing piece 20. Moreover, an avoidance hole is provided on the collection head cover 14, and a part of the suction and discharge piece 13 passes through the avoidance hole. Specifically, the collection head cover 14 can be connected to the mixing tube 22 through a threaded structure. When the collection piece 10 is inserted into the mixing tube 22 and the conduction structure conducts the preservation liquid chamber 21 and the mixing chamber, the collection head cover 14 can be connected to the mixing tube 22 to make the mixing chamber of the mixing tube 22 form a closed structure. At this time, the mixing tube 22 can be shaken to mix the sample and the preservation liquid. Specifically, the silica gel suction head is connected to the body 11, and the silica gel suction head is nested with the collection head cover 14. Moreover, the collection head cover 14 can be assembled with the mixing tube 22 to realize the sealing of the mixing tube 22 and the handheld part of the collection piece 10.

[0058] As Figure 7 shown, the solid collection part 12 includes a plurality of convex walls 121. The plurality of convex walls 121 are arranged at intervals along the circumferential direction of the collection end. A sample collection area is formed between two adjacent convex walls 121. The number of convex walls 121 can be set according to actual needs. For example, it is composed of 3, 5, 8, or 10 convex walls 121, etc., and the space of the collection area can be set to the required size according to needs. When using the collection piece to collect solid feces, the fecal sample can be gathered in the sample collection area. When the sample collection area of the solid collection part 12 is filled with solid feces, the quantitative collection of the sample is completed. In this embodiment, the solid collection part 12 includes four convex walls 121, and the four convex walls 121 are arranged at equal intervals along the circumferential direction of the collection end. By setting the height of the solid collection part 12 and the width of the convex walls 121, the quantitative collection of fecal samples can be realized.

[0059] To facilitate the mixing of fecal samples and preservation liquid, through holes 121a are provided on the surface of at least one convex wall 121, and the through holes 121a communicate with the sample collection area. By providing the through holes 121a on the surface of the convex walls 121, when it is necessary to mix the fecal sample and the preservation liquid, the preservation liquid can wash the convex walls 121 through the through holes 121a, preventing the fecal sample from sticking to the convex walls 121 and being difficult to fall off. Through this structure, the homogenization operation of fecal samples and preservation liquid can be facilitated. Specifically, due to the small size of the collection piece and the narrow structure of the convex walls 121, in order to increase the aperture as much as possible to allow liquid and samples to pass through the aperture, the through holes 121a are considered to be designed as rectangular small holes, or the through holes 121a can be designed as round holes or other hole shapes according to specific usage situations. The through holes 121a can be provided on the spaced convex walls 121 or on all the convex walls 121. In this embodiment, the through holes 121a are provided on two of the four convex walls 121 arranged at intervals, and three rectangular small holes are arranged at intervals along the length direction of each convex wall 121.

[0060] Among them, the convex wall 121 has a relatively arranged free end 121b and a connecting end 121c. The connecting end 121c of the convex wall 121 is connected to the side wall of the collection end. By setting the thickness of the free end 121b to be less than that of the connecting end 121c, on the one hand, when using the collection piece to collect solid feces, it is convenient to insert the solid collection part 12 into the solid feces; on the other hand, when rotating the collection piece, the resistance received by the convex wall 121 can be reduced, which is convenient for sample collection.

[0061] Specifically, the convex wall 121 bends in a direction away from the main body 11, and the bending directions of each convex wall 121 are the same. For example, they can all bend clockwise, all bend counterclockwise, or other bending situations. In this embodiment, the convex wall 121 forms a wheel-shaped fan blade structure in the clockwise direction. Among them, the opening direction, angle, quantity of the convex wall 121, the shape, aperture, quantity of the holes on the convex wall 121, the height of the convex wall 121, etc. can all be adjusted accordingly according to the actual sampling requirements.

[0062] And, in order to seal the other end of the mixing piece 20, the mixing piece 20 further includes a mixing tube cover 26, and the mixing tube cover 26 is threadedly connected to the other end of the mixing tube 22 opposite to the collection head cover 14.

[0063] Among them, the mixing piece 20 further includes a mixing bead 27. The mixing bead 27 is movably arranged in the mixing tube 22, and the mixing bead 27 can be used to assist in mixing the sample and the preservation liquid. In this embodiment, the mixing bead 27 includes a steel bead and a glass bead. Specifically, the mixing bead 27 is a stainless steel bead with a diameter of 5-7 mm.

[0064] Specifically, after the collection piece 10 and the mixing piece 20 are combined into a set, they can be placed and sent to the user separately. The collection component is mainly used for mixing and preserving the sample.

[0065] As Figure 2 shown, another embodiment of the present invention provides a collection device, which includes a collection component and a filtering component 30. Among them, the collection component is the collection component provided above, and the filtering component 30 is detachably connected to the collection component. The filtering component 30 is used to filter the mixed liquid of the sample and the preservation liquid. By setting the collection device separately into the collection component and the filtering component 30, the user can use the collection component to collect the sample, and the tester can use the filtering component 30 to filter the mixed liquid of the sample and the preservation liquid collected by the user. Specifically, the filtering component 30 can be used to filter food residues or other large particle residues in the sample, improving the efficiency of subsequent sample pretreatment and detection.

[0066] As Figures 4 to 6As shown in the figure, the filtering component 30 includes a filtering tube 31 and a filtering net 32. Among them, the filtering tube 31 has a first end and a second end which are oppositely arranged. The first end of the filtering tube 31 is detachably connected to the mixing tube 22 of the sampling component. The filtering net 32 is arranged inside the filtering tube 31. When the mixed liquid flows through the filtering net 32, the filtering net 32 can filter the mixed liquid, and the filtering aperture of the filtering net 32 is about 1 mm. In this embodiment, the filtering net 32 and the filtering tube 31 are of an integrally formed structure, which can ensure the use stability of the device. In other embodiments, the filtering net 32 can be set as an independent component.

[0067] By providing the filtering component 30, particles in the feces larger than the filtering diameter can be filtered by the filtering component 30. After the sample is filtered by this structure to remove large particle residues, on the one hand, the preservation effect of the sample in the preservation liquid can be improved to a certain extent. On the other hand, it can avoid large particles blocking the pipette tip during subsequent detection sampling, which affects the sampling of the pipette or pipetting instrument.

[0068] In order to seal the sampling component, the mixing member 20 of the sampling component further includes a protective plug 25. The protective plug 25 is clamped inside the mixing tube 22 and is arranged close to the outlet of the mixing tube 22. When the user finishes sampling with the sampling member 10, since the outlet of the mixing tube 22 is provided with the protective plug 25 and the inlet of the mixing tube 22 is provided with the sampling head cover 14, the mixing tube 22 can form a sealed structure, and the mixed liquid will not leak from the sampling component. Specifically, the protective plug 25 has a second blocking position and a second opening position which are oppositely arranged. When the protective plug 25 is located at the second blocking position, the protective plug 25 blocks the outlet of the mixing tube 22. By providing a boss 33 inside the filtering tube 31 and making the boss 33 correspond to the protective plug 25, since the relative position between the filtering tube 31 and the mixing tube 22 is adjustable, by adjusting the relative position between the filtering tube 31 and the mixing tube 22, the boss 33 can be used to drive the protective plug 25 to move. When the protective plug 25 moves from the second blocking position to the second opening position, the mixing tube 22 is communicated with the filtering tube 31. Moreover, by providing the protective plug 25, during the process of connecting the filtering tube by the tester, the mixing tube can be replaced in the vertical direction without liquid leakage.

[0069] Specifically, when the protective plug 25 is pushed into the mixing tube, due to the existence of the boss 33, even if a centrifugal force is applied subsequently to accelerate the sample filtration, it will not cause the protective plug to block the lower pipe or the filter net, thus blocking the sample from flowing into the filtering tube.

[0070] Among them, a push-pull structure can be provided between the filter tube 31 and the mixing tube 22, and the relative position between the filter tube 31 and the mixing tube 22 can be adjusted by using the push-pull structure, or the filter tube 31 and the mixing tube 22 can be threadedly connected, and the relative position between the filter tube 31 and the mixing tube 22 can be adjusted by rotating the filter tube 31 relative to the mixing tube 22. In this embodiment, the filter tube 31 and the mixing tube 22 are threadedly connected.

[0071] In order to facilitate the collection of the filtered liquid, the collection device further includes a collection tube 40, which is detachably connected to the filter assembly 30, and is used to collect the liquid filtered by the filter assembly 30. The collection tube 40 is detachably connected to the second end of the filter tube 31. Specifically, the collection tube 40 is threadedly connected to the second end of the filter tube 31.

[0072] Among them, a one-dimensional code or a two-dimensional code can be printed on the bottom and side of the filter tube 31 and / or the collection tube 40 for sample information tracking and recording. As needed, the tube cover of the collection tube 40 can be a hexagonal groove, and the tube bottom can be hexagonal or hexagonal card pattern, so that the structure of the cover and the tube bottom can be fixed by the corresponding opening instrument and realize the automatic opening of the instrument. The tube bottom is conical, which is convenient for biological sample processing and use.

[0073] The method of using the device provided in this embodiment is as follows:
