Description

Technical Field

[0001] The utility model relates to the technical field of medical testing instruments, and particularly relates to a fecal sample collection and storage sampling tube with a simple picking function. Background Art

[0002] Fecal collection is often used in medical clinical tests and intestinal flora analysis. The sampling devices of existing fecal sampling tubes are all rod-shaped or flat spoon-shaped. It is difficult to control the sampling amount when collecting samples, and it is difficult to collect effective and practically useful fecal samples for subjects with slightly loose stools.

[0003] In the existing related technologies, for example, the patent with the publication number CN216955403U proposes a fecal sample collection device. When sampling, hold the tube cap and rotate it to remove the tube cap together with the sampler from the tube body. Take an appropriate amount of fecal sample through the sampling part on the sampler, then put the sampler back into the mixing cavity of the tube body, add an appropriate amount of preservation solution (containing nucleic acid lysis solution) into the mixing cavity of the tube body, so that the spoon-shaped structure of the sampling part is immersed in the preservation solution, and reinstall the tube cap onto the opening of the tube body to seal the opening, which is convenient for sample preservation and transportation.

[0004] The above patent takes an appropriate amount of fecal sample through the sampling part on the sampler, and its sampling part is a device similar to a spoon. For some fecal samples with larger volume or stronger adhesiveness, there may be a situation of adhesion and difficulty in disconnection during sampling, and it is also not convenient to control the sampling amount. Therefore, the utility model provides a fecal sample collection and storage sampling tube with a simple picking function. Summary of the Utility Model
