the lower end of the fecal collector is provided with a solid sampling brush and a sampling tube, so that the solid or liquid fecal sample can be collected at multiple points; the excrement collector and the excrement collecting pipe are combined through the sealing threads, so that the samples can be diluted and uniformly mixed, stored in a sealing manner and transported; the fecal collecting pipe, the filter and the sample storage pipe are combined through sealing threads, so that coarse filtration of a sample can be realized; the sample storage tube and the sample storage tube sealing cover are combined through the sealing threads, so that the sealed storage and transportation of the sample can be realized. This novel excrement and urine collection processor makes excrement and urine sample multiple spot gather, dilutes preserve and a series of work such as coarse filtration compact link up, airtight concentrated for sample collection flow is standardized, and the simple operation has promoted work efficiency, and the sample ration of gathering simultaneously is accurate, safe pollution-free, easily preserves and transportation. The invention can provide convenience for downstream fecal nucleic acid extraction, intestinal flora separation and the like.
The above is only a preferred embodiment of the present invention and is not intended to limit the present invention in any way. According to the technical essence of the invention, all technical schemes under the concept of the invention belong to the protection scope of the invention, and in particular, any modification, equivalent replacement, improvement and the like of the above examples are regarded as the protection scope of the invention without departing from the principle of the invention.
