Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially a novel excrement sample collection device. BACKGROUND

[0002] Excrement sample collection is to detect and analyze various components in excrement, commonly used in disease diagnosis, intestinal health research, environmental monitoring, food safety and other fields. Excrement sample can provide important information about digestive system health, intestinal microbial community, pathogen infection, etc. The collection process must strictly follow standard operating procedures to ensure the representativeness, reliability of the sample and accuracy of the analysis results. When processing excrement samples, various different devices are often used to collect, filter and detect and analyze them. However, the collection and filtration of excrement residues are cumbersome, and excrement residues can easily block the instrument or cause non-specific adsorption of the reaction liquid, affecting the accuracy of the detection. Due to the particularity of excrement samples, if the excrement residues in the excrement samples cannot be quickly and effectively processed, it will bring discomfort to the physiological and psychological of the operator.

[0003] In the traditional technology, the structure of the collection and filtration device is often improved to achieve more convenient and rapid processing of excrement samples.
