Description

Technical Field

[0001] The utility model relates to the technical field of feces sample processing, in particular to a feces sample collection and processing tube. Background Art

[0002] Fecal nucleic acid testing is a new testing item that has emerged in recent years. By detecting host free nucleic acid and intestinal microbial nucleic acid in feces, some pathological and physiological changes in the intestine can be understood, which can be used for the diagnosis of intestinal diseases (such as non-invasive early diagnosis of colorectal cancer) and treatment (such as fecal flora transplantation treatment). Correct sample collection and preparation is the first step in the detection work, and it is also a key step to ensure the accuracy of the test results. At present, feces collection in medical institutions mostly requires patients to use a disposable collection spoon to scrape the feces and put it into a collection box. After it is sent to the laboratory, the inspector picks the feces in the collection box, dilutes it, and then performs related operations such as host or intestinal microbial nucleic acid extraction.

[0003] For example, the patent number CN201711119197.0 disclosed a new type of stool collection processor on 2018-03-20, which belongs to the field of medical device technology. It includes a stool collection tube, a stool collector, a sample storage tube, a filter and a sample storage tube sealing cover. The lower end of the stool collector is provided with a sampling brush and a sampling tube to realize multi-point collection of solid or liquid stool samples; the stool collector and the stool collection tube are sealed to realize dilution, mixing, sealed storage and transportation of the sample; the stool collection tube, the filter and the sample storage tube are sealed to realize coarse filtration of the sample; the sample storage tube and the sample storage tube sealing cover are sealed to realize sealed storage and transportation of the sample. The new stool collection processor makes a series of work such as multi-point collection, dilution, storage and coarse filtration of stool samples compactly connected, and carried out in a closed and centralized manner, so that the sample collection process is standardized, the operation is convenient, and the work efficiency is improved. At the same time, the collected samples are quantitatively accurate, safe and pollution-free, and easy to store and transport.

[0004] During the sampling process of the above-mentioned processor, a dropper is needed to take out the sample from the storage tube. The dropper is easily stained with other contaminants during use, thereby contaminating the liquid and causing inaccurate test data. This is why the design is used. Utility Model Content

[0028] Example:

[0029] Reference Figure 1-Figure 8A stool sample collection and processing tube comprises a tube body 1 and a sealing cover 3 detachably connected to the tube body 1, an integrally formed nipple head 305 is arranged on the top of the sealing cover 3, an outer snap ring 303 and a sealing snap ring 302 are fixedly connected to the sealing cover 3, a groove 304 for snapping with a sub-plate 201 is provided on the outer snap ring 303, and an anti-slip pattern 301 is arranged on the outer wall of the sealing cover 3; a mounting ring 2 is embeddedly connected to the tube body 1, a filter screen 202 is fixedly connected to the bottom of the mounting ring 2, and the filter screen 202 is a nylon filter membrane.

[0030] Collect a fecal sample volume (100-500ul), add a treatment solution (1000-500ul), prepare a 1:10 fecal sample suspension, cover the lid, shake, let it stand, then invert and squeeze the nipple head 305. When adding the sample, the feces and the liquid are separated, and the liquid is clarified after passing through the nylon filter membrane. Four drops (about 200ul) can be directly dropped for sample verification and extraction, so there is no need to use a dropper or other tools for sampling, which can avoid contamination of the suspension and avoid contamination during sampling.

[0031] Reference Figure 3 A clamping ring 101 is fixedly connected to the top of the tube body 1, and a clamping groove 102 is opened on the clamping ring 101. The outer wall of the mounting ring 2 is attached to the inner wall of the tube body 1, and the bottom of the mounting ring 2 is fixedly connected to a sub-plate 201 that engages with the clamping groove 102.

[0032] After the sealing cover 3 is removed, the secondary plate 201 can be clamped by the thumb and index finger to facilitate the removal of the mounting ring 2 from the tube body 1 for adding samples or cleaning.

[0033] Reference Figure 2 The bottom of the tube body 1 is fixedly connected with a support plate 104, and the support plate 104 is integrally formed with the tube body 1. The support plate 104 increases the contact area with the desktop, thereby improving the stability of the tube body 1 standing on the desktop.

[0034] Reference Figure 1 , a scale line 103 is provided on the tube body 1 to facilitate observation of the amount of material added into the tube body 1 .

[0035] In summary, the processing tube discharges the required liquid for sample verification and extraction by squeezing the nipple head 305, thereby eliminating the need to use tools such as droppers to take samples, avoiding contamination of the suspension and contamination during sampling. The sub-plate 201 on the side wall of the mounting ring 2 makes it easy to remove the mounting ring 2 from the tube body 1, thereby facilitating the addition of samples into the tank body or cleaning the tank body, the mounting ring 2 and the filter screen 202.
