Description

Technical Field

[0001] The utility model belongs to the technical field of sample collection structures, and particularly relates to a fecal sample collection structure for fecal detection. Background Technique

[0002] At present, the only bacteriological pathogen that is definitely closely related to the occurrence of gastric cancer and is listed as a class I carcinogen, Helicobacter pylori (Hp) infection has always been a key object for early screening and intervention. Helicobacter pylori is a pathogenic bacterium related to a variety of major chronic diseases, is contagious, and can cause a variety of gastrointestinal and extra-gastrointestinal diseases including Helicobacter pylori gastritis, peptic ulcer, gastric MALT lymphoma, primary immune thrombocytopenia, etc. After being infected with Helicobacter pylori, it is difficult to heal on its own, bringing a heavy disease burden to patients. If not treated, it often shows a state of lifelong infection, and in severe cases, it can cause gastric cancer.

[0003] Patent CN220079064U discloses a quantitative collection and preservation tube for fecal samples with a novel and easily absorbable preservation solution, which can quantitatively collect fecal samples and contains a filtering device. However, its quantitative sampler is not convenient for manual sampling. Secondly, the structure of its filtering device cannot penetrate the sampler for filtering. Thirdly, it uses two 304 stainless steel mixing balls with a diameter of 5.6 mm - 11.1 mm for oscillating, mixing, and homogenizing. For a large sample size, the homogenizing strength is insufficient, and it is difficult to obtain a homogeneous solution fully and quickly, thus effectively protecting the detected substances.

[0004] Patent CN115791275A discloses a fecal collection and preservation device with a quantitative sampling function and a filtering function, including a sample collection device and a sample preservation device. It has a certain quantitative function and filtering function, but it can only collect samples of about 1 g, and at the same time, it does not have a relevant homogenizing function.

[0005] Patent CN220104515U discloses a quantitative fecal sampling device. The sample volume collected quantitatively is very small, not suitable for large-sample gene detection, and at the same time, it does not have a homogenizing function.

[0006] Patent CN108414263A discloses an integrated fecal sample collection device and method. Its preservation solution is in the storage area, and the sample collection is by a spiral collection rod, which is difficult to achieve for large samples. At the same time, the solution after filtration is not easy to absorb, and it does not have a homogenizing function.

[0007] Patent CN217483891U discloses a fecal specimen collection and preservation tube suitable for multiple uses, which is convenient for patients to manually pick up the hard collection tube and preservation tube. A patient can pick up the whole device with one hand, but it cannot quantitatively collect fecal samples, and there is no corresponding preservation and homogenizing device, which will cause the degradation of the detected substances in the sample, thus having an adverse impact on downstream detection.

[0008] Patent CN211179133U discloses a fecal sample quantitative collection device, including a sampling device and a preservation device. Although it can quantitatively sample, it lacks a preservation liquid device and a homogenization device, which is not conducive to the stable preservation of samples for detection purposes.

[0009] The prior art has defects: 1. Conventional fecal sampling devices cannot quantitatively or flexibly quantitatively collect; 2. There is no corresponding preservation method for fecal samples after collection; 3. The collected fecal samples cannot be efficiently homogenized and preserved with the preservation liquid; 4. There is no corresponding filtration sedimentation, inhibitor adsorption device, and purification liquid discharge or suction device for the homogenized fecal samples. Summary of the Utility Model
