Microbiome research: Fecal samples are used in microbiome research to understand the rationality of gut microbiota distribution and the presence of pathogenic bacteria. 5. Metabolomics research: Metabolites in fecal samples have the strongest correlation with the gut microbiome, contributing to understanding the role of the gut microbiota and metabolites in disease mechanisms and the discovery of biomarkers. 6. Parasite and Egg Detection: Fecal samples are used to examine for parasites, larvae, and eggs in the stool to diagnose parasitic infections. 7. Occult Blood Detection: Used to detect trace amounts of blood in stool, aiding in the diagnosis of gastrointestinal bleeding. 8. Advances in Automation Technology: Fecal sample analysis techniques are constantly evolving, and automated equipment can improve the efficiency and accuracy of fecal testing. 9. Quality Control and Proficiency Testing: Fecal samples are used in clinical laboratories for internal quality control and external quality assessment to ensure the accuracy and reliability of test results. In conclusion, fecal samples play a vital role in multiple fields, including medical diagnostics, disease research, and microbiome and metabolomics research.

[0003] When collecting stool samples, the patient's stool and urine must not be mixed. Clean, uncontaminated stool must be collected, and the sample should be extracted from the inside of the stool. Therefore, special collection devices are often required when collecting patient stool samples. Common stool sample collection devices in the prior art include: 1. The MGIEasy stool sample collection kit, which is suitable for the collection and preservation of stool samples and can preserve stool samples for 14 days at room temperature. 2. A stool collection kit, which includes a screw-cap plastic container, a wooden scraper, a patient tag, and a biohazard bag. The patient uses the scraper to transfer approximately 1-2 teaspoons of stool from areas with blood or mucus into the collection container.

[0004] This application provides a novel spiral-shaped fecal sample collection device that facilitates sample collection and transfer. Utility Model Content

[0005] This invention provides a novel spiral-shaped fecal sample collection device that facilitates sample collection and transfer.

[0006] To achieve this objective, the present invention provides the following technical solution:

[0007] This utility model provides a spiral-shaped fecal sample collection device, including an outer sleeve and a sampling component. The outer sleeve can be sleeved on the outside of the sampling component. The sampling component includes a spiral sampling part and a rod part. The outer sleeve is hollow inside, and the top surface of the outer sleeve is provided with a through hole that matches the rod part. The bottom surface of the outer sleeve is provided with a small hole through which the sampling part can pass.

[0008] In one state, the sampling part of the sampling component is placed inside the outer sleeve. In another state (in the use state), the rod body is rotated to rotate the spiral-shaped sampling part out of the small hole until the sampling part extends out of the outer sleeve.

[0009] Preferably, the rod body includes an upper cylindrical rod and a lower cylindrical rod. The outer diameter of the upper rod is smaller than the outer diameter of the lower rod. The diameter of the through hole on the top surface of the outer sleeve is larger than the outer diameter of the upper rod and smaller than the outer diameter of the lower rod. The lower rod is placed inside the outer sleeve.

[0010] In this invention, the rod body is designed as an upper rod and a lower rod with different diameters. This facilitates the positioning of the rod body and the outer sleeve, ensuring that the larger-diameter lower rod is always confined within the outer sleeve. This prevents the rod body from excessively retracting after use, which could lead to separation of the outer sleeve and the sampling assembly.

[0011] Preferably, it also includes a rotating ring, which is disposed at the top end of the rod body.

[0012] In this invention, the rotating ring facilitates the operator's rotation of the sampling component. Anti-slip textures can also be added to the rotating ring.

[0013] Preferably, the small hole on the bottom surface of the outer sleeve is semi-elliptical. The semi-elliptical small hole facilitates the rotation and passage of the spiral sampling section.

[0014] Preferably, it also includes a sealing ring, which is disposed at the connection between the outer sleeve and the rod portion of the sampling assembly.

[0015] In this embodiment, the sealing ring increases the stability of the entire sampling device.

[0016] Preferably, it also includes a plurality of soft baffles, which are respectively disposed around the small holes on the bottom surface of the outer sleeve.

[0017] In this embodiment, the soft baffle does not affect the passage of the sampling section. On the other hand, when the sampling section retracts after collecting feces, the soft baffle can easily scrape off the fecal sample on the sampling section, thereby ensuring that a sufficient amount of sample is collected.

[0018] Preferably, the spiral sampling section and the rod section are detachably connected.

[0019] Preferably, the upper rod and the lower rod are an integral structure.

[0020] Preferably, the outer sleeve is cylindrical.

[0021] Preferably, the outer sleeve is made of transparent plastic.

[0022] The usage method of the spiral-shaped fecal sample collection device of this invention is briefly summarized as follows:

[0023] S1. When not in use, the spiral sampling section and the lower rod are placed inside the outer sleeve.

[0024] S2. When needed, the operator rotates the rotating ring, and the sampling component rotates together with the rotating ring. At this time, the sampling part rotates out from the small hole of the outer sleeve.

[0025] S3. Continue until the entire sampling section is exposed. At this point, the upper rod is placed inside the outer sleeve.

[0026] S4. Insert the sampling part into the feces and rotate it several times to fill the internal thread gap of the spiral sampling part with feces.

[0027] S5. After sampling, place the sampling part into the sample collection tube and rotate the rotating ring in the opposite direction. At this time, the sampling part retracts into the outer sleeve. Since there is only one small hole on the bottom surface of the outer sleeve for the sampling part to pass through, the other parts of the bottom surface of the outer sleeve can prevent feces from entering the outer sleeve. At the same time as the sampling part is retracted, the fecal sample is released into the sample collection tube, completing the sample sampling.

[0028] Compared with existing technologies, the beneficial effects and significant advancements of this invention are as follows: The spiral-shaped fecal sample collection device of this invention uses a spiral-shaped sampling section to facilitate the acquisition of a sufficient amount of fecal sample. When the sample is transferred to the sample collection tube, the outer sleeve and the sampling section cooperate to scrape the fecal sample from the sampling section into the sample collection tube. The spiral-shaped fecal sample collection device of this invention has a reasonable overall design and is easy to use. It is a brand-new fecal sample collection device that facilitates the collection and transfer of samples. Attached Figure Description

[0043] The technical solution of this utility model will now be described in detail with reference to specific embodiments.

[0044] Example 1

[0045] like Figure 1 As shown, a spiral-shaped fecal sample collection device includes an outer sleeve 1 and a sampling component 2, wherein the outer sleeve 1 can be sleeved on the outside of the sampling component 2.

[0046] like Figure 2 As shown, the sampling assembly 2 includes a spiral sampling section 2.1 and a rod section. The rod section includes an upper cylindrical rod 2.3 and a lower cylindrical rod 2.2. The outer diameter of the upper rod 2.3 is smaller than the outer diameter of the lower rod 2.2. The diameter of the through hole on the top surface of the outer sleeve 1 is larger than the outer diameter of the upper rod 2.3 and smaller than the outer diameter of the lower rod 2.2. The lower rod 2.2 is placed inside the outer sleeve 1. The outer sleeve 1 is hollow inside, and the top surface of the outer sleeve 1 has a through hole that matches the rod section. Figure 3 As shown, the bottom surface of the outer sleeve 1 is provided with a small hole 1.1 through which the spiral sampling part 2.1 can pass.

[0047] like Figure 1 and 2 As shown, the spiral-shaped fecal sample collection device of this embodiment also includes a rotating ring 3, which is disposed at the top end of the rod body. In this embodiment, the operator can rotate the spiral-shaped sampling part 2.1 out of the outer sleeve 1 by rotating the rotating ring 3.

[0048] like Figure 3 As shown, in the spiral-shaped fecal sample collection device of this embodiment, the small hole 1.1 on the bottom surface of the outer sleeve 1 is semi-elliptical.

[0049] like Figure 1 and 2 As shown, the spiral-shaped fecal sample collection device of this embodiment also includes a sealing ring 4, which is disposed at the connection between the outer sleeve 1 and the rod part of the sampling component 2.

[0050] In this embodiment, the spiral sampling part 2.1 and the rod, the upper rod body part 2.3 and the lower rod body part 2.2 are an integral structure.

[0051] In this embodiment, the outer sleeve 1 is a cylinder. Furthermore, the outer sleeve 1 is made of transparent plastic.

[0052] The usage method of the spiral-shaped fecal sample collection device in this embodiment is briefly summarized as follows:

[0053] Step 1: When not in use, the spiral sampling section 2.1 and the lower rod 2.2 are both placed inside the outer sleeve;

[0054] Step 2: When needed, the operator rotates the rotating ring 3, and the sampling component 2 rotates together with the rotating ring 3. At this time, the sampling part 2.1 rotates out from the small hole 1.1 of the outer sleeve 1.

[0055] Step 3: Continue until the sampling section 2.1 is fully exposed. At this point, the upper rod 2.3 is placed inside the outer sleeve 1.

[0056] Step 4: Insert the sampling part 2.1 into the feces. You can rotate it a few times to fill the screw thread gap inside the spiral-shaped sampling part 2.1 with feces.

[0057] Step 5: After sampling, place the sampling part 2.1 into the sample collection tube and rotate the rotating ring 3 in the opposite direction. At this time, the sampling part 2.1 retracts into the outer sleeve 1. Since there is only one small hole 1.1 on the bottom surface of the outer sleeve 1 that allows the sampling part 2.1 to pass through, the other parts of the bottom surface of the outer sleeve 1 can prevent feces from entering the outer sleeve 1. At the same time as the sampling part 2.1 retracts, the fecal sample is released into the sample collection tube, completing the sample sampling.

[0058] Example 2

[0059] The spiral-shaped fecal sample collection device in this embodiment has a structure that is basically the same as that in Embodiment 1, with at least the following differences.

[0060] like Figure 4 As shown, in this embodiment, the spiral-shaped fecal sample collection device also includes multiple soft baffles 5, which are respectively disposed around the small holes 1.1 on the bottom surface of the outer sleeve 1. The soft baffles 5 are triangular.

[0061] In this embodiment, the spiral-shaped sampling section 2.1 and the rod section are detachably connected. The connection can be made detachably via the spiral.

[0062] The usage method of the spiral-shaped fecal sample collection device in this embodiment is briefly summarized as follows:

[0063] Step 1: When not in use, the spiral sampling section 2.1 and the lower rod 2.2 are both placed inside the outer sleeve;

[0064] Step 2: When needed, the operator rotates the rotating ring 3, and the sampling component 2 rotates together with the rotating ring 3. At this time, the sampling part 2.1 rotates out from the small hole 1.1 of the outer sleeve 1.

[0065] Step 3: Continue until the sampling section 2.1 is fully exposed. At this point, the upper rod 2.3 is placed inside the outer sleeve 1.

[0066] Step 4: Insert the sampling part 2.1 into the feces. You can rotate it a few times to fill the screw thread gap inside the spiral-shaped sampling part 2.1 with feces.

[0067] Step 5: After sampling, place the sampling part 2.1 into the sample collection tube and rotate the rotating ring 3 in the opposite direction. At this time, the sampling part 2.1 retracts into the outer sleeve 1. Since the bottom surface of the outer sleeve 1 has only one small hole 1.1 through which the sampling part 2.1 can pass, and soft baffles 5 are provided around the small hole 1.1, the other parts of the bottom surface of the outer sleeve 1 and the soft baffles 5 can prevent feces from entering the outer sleeve 1. At the same time as the sampling part 2.1 is retracted, the fecal sample is released into the sample collection tube, completing the sample sampling.
