Description

Technical Field

[0001] The invention relates to the technical field of fecal parasite detection, and more particularly to a reusable parasite detection sampling and grinding device. Background Art

[0002] In clinical research and medical practice, fecal parasite testing is an important diagnostic tool used to identify and quantify parasite eggs and parasite bodies in feces. Traditional fecal parasite testing methods have many inconveniences, including complex operation, low efficiency, high cost, and difficult sample processing. These challenges limit the popularization and application of detection technology, especially in resource-limited settings.

[0003] Existing fecal parasite detection technologies usually involve cumbersome sample collection, processing and analysis steps. These steps are not only time-consuming, but also require professional technicians to operate, increasing the difficulty and cost of detection.

[0004] In addition, traditional sampling and grinding tools are often simple in design and lack effective sample isolation and egg floating mechanisms, which affects the accuracy and reliability of test results.

[0005] Therefore, how to simplify the collection, processing and analysis process of stool samples, improve the efficiency and accuracy of detection, and reduce the operating cost and difficulty is an urgent problem that technicians in this field need to solve. Summary of the invention

[0006] In view of this, the present invention provides a reusable parasite detection sampling and grinding device, aiming to solve the above-mentioned technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] A reusable parasite detection sampling and grinding device, comprising:

The grinding section is rotated to form a grinding gap between its outer wall and the inner wall of the collecting tube.

[0011] Through the above technical solution, the present invention proposes a sophisticatedly designed reusable parasite detection sampling and grinding tube, which aims to simplify the collection, processing and analysis process of fecal samples, improve the efficiency and accuracy of detection, and reduce the operating cost and difficulty.

[0015] Preferably, in the above-mentioned reusable parasite detection sampling and grinding device, the inner wall surface of the collection tube is a frosted surface. The frosted design can enhance the damping feeling at the upper opening of the collection tube and the sampling tube, ensuring a close fit between the two.

[0016] Preferably, in the above-mentioned reusable parasite detection sampling and grinding device, the sampling section includes a sampling rod fixed to the bottom surface of the cylinder, and the bottom end of the sampling rod has a sampling spoon, which greatly facilitates the sample collection process.

[0017] Preferably, in the above-mentioned reusable parasite detection sampling and grinding device, the top of the filtering section has a radially protruding gear, and the lower end face of the gear abuts against the top edge of the collecting tube, so that the operator can hold the gear to rotate the sampling tube.

[0018] Preferably, in the above-mentioned reusable parasite detection sampling and grinding device, the bottom end of the collection tube has a plurality of downwardly protruding support protrusions, and a cross-shaped card slot is formed between the plurality of support protrusions. The support protrusions can facilitate the placement of the collection tube, and the cross-shaped card slot can facilitate its placement and insertion.

[0019] Preferably, in the above-mentioned reusable parasite detection sampling and grinding device, it also includes a sealing cover that is snapped onto the top opening of the collection tube.

[0020] Preferably, in the above-mentioned reusable parasite detection sampling and grinding device, the side wall of the sealing cover has anti-skid bumps, which can facilitate opening of the sealing cover.
