Embodiment Construction

[0069] Hereinafter, a stool sample testing device according to an embodiment of the present invention will be described in detail with reference to the drawings. The stool sample inspection device according to the present embodiment is characterized in that it includes stool collection confirmation means for detecting a sample that has not been collected.

[0070] The sample to be tested in the present invention includes a buffer-containing solution for suspending stool, and more preferably includes a stool sample.

[0071] The stool sample inspection device of the present invention can be used to detect an uncollected stool sample that does not substantially contain a stool sample. "No feces collection" in the present invention means that feces are not substantially contained in the stool collection container. "Substantially not containing feces" in the sample refers to a state in which, as described later, feces equal to or less than the sample amount showing an absorbance ...

Abstract

A stool specimen examining device is characterized by being provided with an intake unit for a sample comprising a stool suspension, a stool collection confirmation unit which detects an uncollected stool specimen on the basis of the light absorbency of the stool suspension measured at a first wavelength, and a sample measuring unit which performs a measurement on the basis of the light absorbencymeasured at a second wavelength. Examination accuracy can be improved by detecting the uncollected stool specimen in a stool specimen examination.

Description

technical field [0001] The invention relates to a technology for examining stool samples. Background technique [0002] Feces as one of biological samples is one of important samples from which information in the digestive tract can be obtained. Most of the feces are water, and the rest are the dead bodies of intestinal wall cells, intestinal bacteria, and food residues. Useful information related to diseases of the digestive system can be obtained through feces, which is helpful for the diagnosis of diseases. [0003] Colorectal cancer, which has been increasing in recent years, has a small amount of blood attached to the surface of the stool when the stool passes through the large intestine in the early stage without symptoms. This tiny amount of blood cannot be identified with the naked eye, so it is called fecal occult blood. Fecal occult blood testing is a test for detecting colorectal polyps and early-stage colorectal cancer through the detection of fecal occult blo...
