The upper end wall 8 of the holding cylinder 13 is communicated with a liquid outlet nozzle 1.

[0051] Specifically, the present utility model provides a disposable feces pretreatment sampler, which includes a dilution cup 3 and a holding cylinder 13. The dilution cup 3 includes a diaphragm 4. A closed pre-filled dilution liquid chamber 6 is formed between the bottom of the dilution cup 3 and the diaphragm 4 for accommodating dilution liquid in the formed pre-filled dilution liquid chamber 6. A transition zone 16 is formed between the cup mouth of the dilution cup and the diaphragm for providing a puncture space for the spike-shaped sampling end. The holding cylinder 13 includes a filter partition 12 and a sampling rod 9. A filter chamber 14 is formed between the upper surface of the filter partition 12 and the upper end wall 8. The lower surface of the filter partition 12 is fixedly connected to one end of the sampling rod 9, so that the sampling rod 9 can be fixed in the holding cylinder 13. The other end of the sampling rod 9 is fixedly connected to a spike-shaped sampling end 7. The spike-shaped sampling end 7 passes through the mouth of the holding cylinder. The dilution cup 3 can be made of a soft material, and the diaphragm 4 is a polyethylene film that is easily pierced by a spike, so that the spike-shaped sampling end 7 can pass through the transition zone to pierce the diaphragm 4. The mouth of the holding cylinder 13 is detachably connected to the cup mouth of the dilution cup 3. The upper end wall 8 of the holding cylinder 13 is communicated with a liquid outlet nozzle 1, so that the liquid in the holding cylinder 13 can flow out from the liquid outlet nozzle 1.

[0052] In a possible implementation manner, an internal thread 2 is provided on the cup mouth of the dilution cup, and an external thread 10 is provided on the outer edge of the mouth of the holding cylinder 13, and the internal thread 2 is threadedly connected to the external thread 10.

[0053] Specifically, in the present utility model, through the threaded connection between the internal thread 2 and the external thread 10, the dilution cup 3 and the holding cylinder 13 can be threadedly connected, so that the spike-shaped sampling end 7 can pierce the diaphragm 4, so that in the case of inverting the dilution cup 3 and the holding cylinder 13, the liquid in the pre-filled dilution liquid chamber 6 can flow out from the diaphragm 4.

[0054] In a possible implementation, the spiked sampling end 7 includes a fixing disk 7-1 and a number of fecal sample segmentation pieces 7-2. Each of the fecal sample segmentation pieces 7-2 has a right trapezoidal structure. Each of the fecal sample segmentation pieces 7-2 includes a fixing edge and a fitting edge that are perpendicular to each other. Each of the fecal sample segmentation pieces 7-2 is fixed to the fixing disk 7-1 through its corresponding fixing edge. Two adjacent fecal sample segmentation pieces 7-2 are attached to each other through their corresponding fitting edges. The beveled edges of each of the fecal sample segmentation pieces 7-2 enclose to form a spiked sampling end portion.

[0055] Specifically, in the present utility model, the spiked sampling end 7 is inserted into the feces to be sampled and quickly taken out, so that a certain amount of fecal samples are stably adhered in the sample groove 7-4 between any two adjacent fecal sample segmentation pieces 7-2 on the spiked sampling end 7. Then, as the spiked sampling end 7 enters the pre-filled dilution liquid chamber 6, the fecal samples are brought into the pre-filled dilution liquid chamber 6.

[0056] In a possible implementation, each of the fecal sample segmentation pieces 7-2 is perpendicular to the fixing disk 7-2.

[0057] Specifically, in the present utility model, since each of the fecal sample segmentation pieces 7-2 is perpendicular to the fixing disk 7-2, six fecal sample segmentation pieces 7-2 can form a spiked sampling end 7, which can then pierce the diaphragm 4.

[0058] In a possible implementation, the number of the fecal sample segmentation pieces 7-2 is six. Any two adjacent fecal sample segmentation pieces 7-2 are attached to each other through their corresponding fitting edges to form a 60° angle.

[0059] Specifically, in the present utility model, by setting the number of the fecal sample segmentation pieces 7-2 to six, and any two adjacent fecal sample segmentation pieces 7-2 are attached to each other through their corresponding fitting edges to form a 60° angle, the six fecal sample segmentation pieces 7-2 can be circumferentially distributed to form a concentrated spiked tip, which can concentrate on piercing the diaphragm 4.

[0060] In a possible implementation, a limiting outer edge 11 is provided at the upper end of the external thread 10 of the holding cylinder 13. An annular inner edge 5 is provided on the inner wall of the dilution cup 3. The outer contour of the diaphragm 4 is heat-sealed on the annular inner edge 5.

[0061] Specifically, in the present utility model, an external thread 10 is provided at the lower end of the holding cylinder 13, and an internal thread 2 is provided at the upper end of the dilution cup 3. A limiting outer edge 11 is provided on the upper part of the external thread 10 of the holding cylinder 13. When the external thread 10 of the holding cylinder 13 is in threaded engagement with the internal thread 2 of the dilution cup 3, the spike-shaped sampling end 7 extends downward into the dilution cup 3. When the external thread 10 of the holding cylinder 13 is fully tightened with the internal thread 2 of the dilution cup 3, the spike-shaped sampling end 7 pierces the diaphragm 4. The annular inner edge 5 can limit the screwing degree of the internal thread 2 and the external thread 10, limit the position of the internal thread 2, and thus limit the piercing position of the spike-shaped sampling end 7.

[0062] In a possible implementation manner, a detachable sealing cap 15 is provided on the liquid outlet nozzle 16.

[0063] Specifically, in the present utility model, by providing a detachable sealing cap 15 on the liquid outlet nozzle 16, the liquid in the pre-filled dilution liquid chamber 6 can be sealed by the sealing cap.

[0064] Working principle:

[0065] When leaving the factory and during sales, it is recommended to pack the dilution cup 3 and the holding cylinder 13 separately, as Figure 1 and Figure 2 shown; during use, the dilution cup 3 is placed vertically on the tabletop. The medical staff holds the holding cylinder 13 by hand, inserts the spike-shaped sampling end 7 into the feces to be sampled and quickly takes it out. At this time, a certain amount of fecal samples are stably adhered in the sample slots 7-4 between any two adjacent fecal sample dividing pieces 7-2 on the spike-shaped sampling end 7; then the spike-shaped sampling end 7 with the sample taken is extended downward into the dilution cup 3, as Figure 3 , and the external thread 10 of the holding cylinder 13 is in threaded engagement with the internal thread 2 of the dilution cup 3. At this time, a transition chamber 16 is formed between the diaphragm 4 and the filter partition 12. When the external thread 10 of the holding cylinder 13 is fully tightened with the internal thread 2 of the dilution cup 3, as Figure 4 shown, the spike-shaped sampling end 7 tears and pierces the diaphragm 4 in a rotational stirring form;

[0066] Then the combined structure composed of the dilution cup 3 and the holding cylinder 13 is turned upside down, as Figure 5 , the dilution liquid in the pre-filled dilution liquid chamber 6 flows downward through the centrally damaged diaphragm 4 into the transition chamber 16. During the process that the dilution liquid in the dilution liquid chamber 6 flows downward through the centrally damaged diaphragm 4 into the transition chamber 16, the spike-shaped sampling end 7 is washed and wetted. Then, by shaking, the samples on the spike-shaped sampling end 7 are fully dispersed in the dilution liquid. Subsequently, the dilution liquid with the samples dispersed in the transition chamber 16 flows downward through the filter holes on the filter partition 12 to filter the residue under the action of gravity and then continues to flow into the filtered chamber 14, so that there are no large particle soluble residues in the dilution liquid in the filtered chamber 14;

[0067] Then remove the liquid outlet nozzle 16, and finally squeeze the soft dilution cup 3 to make the uniform dilution liquid in the filtered bin 14 drop on the test paper, such as the occult blood test paper or the Helicobacter pylori test paper. After waiting for a certain period of time, finally interpret the result. The whole process is convenient and fast, with a comprehensive sampling and dilution process, and it avoids a large amount of insoluble residues in the stool sample from dropping on the test paper.
