Sample storage drip hopper

technical field

The utility model relates to the technical field of biological detection equipment, in particular to a drip hopper for sample storage used in a disposable feces centrifugal collector.

Background technique

Fecal testing is of great significance for the early screening of many diseases. By testing hemoglobin in feces, it is possible to screen patients for gastrointestinal bleeding. Therefore, fecal testing has become a routine item in many medical units to detect diseases.

A traditional stool collector has only two parts - a test tube and a sealing cap, where the test tube holds the sample. When testing, the sample is poured from the mouth of the test tube, which has the defect of inconvenient operation. Another example is the "disposable feces centrifugal collector" disclosed in the CN 201621336000.X patent document (authorized publication number is CN206208562U), and its main structure is: comprising a test tube, a filter and a drip bucket, and the test tube is connected to the filter through the filter.
