Excrement detection device and excrement detection method

Abstract

The invention relates to an excrement detection device and an excrement detection method. The excrement detection device comprises a sampling detection assembly; the sampling detection assembly comprises a sampling pipe, a pipe cover assembled on the sampling pipe, a test paper bin arranged on the side wall of the sampling pipe, a piston arranged in the sampling pipe and a screw connected with thepiston; the lower end part of the screw protrudes downwards out of the bottom wall of the sampling pipe; a nut is assembled at the lower end part of the screw; a liquid through hole for communicatingthe test paper bin with the sampling pipe is formed on the side wall of the sampling pipe; a pipe cavity of the sampling pipe is divided into an upper cavity and a lower cavity by the piston; by rotating the nut, the screw and the piston can be driven to reciprocate in an up-and-down direction together; when the piston is positioned at a lower end point of the reciprocation motion, the liquid through hole is communicated with the upper cavity; and when the piston is positioned at an upper end point of the reciprocation motion, the liquid through hole is separated from the upper cavity by thepiston. The excrement detection device and the excrement detection method have the advantages of convenience for operation, controllable operation process, high automation degree and capacity of continuously storing mixed liquid after detection.

Description

technical field [0001] The invention relates to medical equipment, in particular to a stool detection device and a stool detection method. Background technique [0002] The pathogens, occult blood, and tumor exfoliation in the stool sample are detected by biochemical test strips, and the diagnosis of the disease can be realized according to the detected indicators. The operation process mainly includes: 1. Collecting fecal samples with a sampling stick; 2. Transferring the fecal samples into a test tube filled with buffer solution, and homogenizing by stirring, shaking, etc. to form a sample liquid; 3. Using a straw to absorb 4. After waiting for a certain period of time, read the result. [0003] Fecal analysis in the prior art is mainly done manually, which is not only inefficient, but also heavily dependent on professionals, which is less convenient and likely to delay the timing of diagnosis; in addition, the special properties of feces are also likely to make operators...

AI Technical Summary

Problems solved by technology

However, the feces detection device in the prior art has the following problems: the operation is complicated, and it is difficult to control the volume of the sample liquid that reacts with the test paper, thereby affecting the consistency of the detection results; Due to the poor sealing performance, the sample liquid in the sampling tube is easily polluted or leaked, and the sample liquid in the sampling tube cannot be preserved for next use; the degree of automation is low, and operators are still required to homogenize, remove barriers and interpret results wait for operation
