Description

Excrement sample treatment collector

Technical Field

The invention relates to the technical field of biological detection equipment, in particular to an instrument for processing and collecting a fecal sample.

Background

The traditional excrement collector only comprises two parts, namely a test tube and a sealing cover, wherein a collecting spoon is arranged in the sealing cover, and the upper end of the sealing cover can be opened. When the sample collecting device is used, the collected substance is placed into a test tube to be diluted, the upper end of the sealing cover is opened, and a sample to be detected is dripped onto the detection strip. Often, impurities in the test tube are not filtered, thereby affecting the detection result.

In order to solve the above technical problems, a fecal sample treatment and sampling device is improved and designed, for example, a fecal tester disclosed in the patent document CN 201711348914.7, which has the following main structure: the inspection group comprises an acquisition container, an acquisition chamber is arranged in the acquisition container, a joint cover and a stool taking piece are arranged at the top end cover of the acquisition chamber, a filter screen and a through hole are arranged at the position close to the bottom of the acquisition chamber, the inspection container is arranged in the inspection container, a funnel, a gasket and an outlet are arranged at the bottom of the inspection chamber, an extruding device and a bottom cover are arranged outside the outlet, and therefore the inspection group flows out or blocks a solution to be inspected through the extruding device, convenience is improved, sanitation is improved, and the funnel and the gasket enable fine substances in a fixed-volume inspection body to be prevented from being mixed with a supernatant during extrusion, and the concentration of the fine substances in the inspection body to be observed is prevented from being diluted during extrusion. However, the stool tester has the following defects: 1. the bottom through hole of the collection group is pre-plugged by adopting a diaphragm and a tail cover, and then the tail cover is screwed off and the diaphragm is removed, so that the collection of a sample is realized by sleeving the collection group with a detection container; during collection operation, the through hole is subjected to sleeving detection container operation after the diaphragm is removed, the risk that sample liquid drops leak to stain operators exists at the through hole, and residual liquid flows out at the through hole when the detection container is withdrawn, so that the sensory discomfort of the operators is easily caused; 2. the excrement taking part is short, so that the operation is inconvenient.
