A detection device and method based on photoelectric detection

Abstract

The invention relates to a detection device and method based on photoelectric detection. In the device, the paper box to be tested is fixed at the rear of the toilet and is located under the water tank; the paper box to be tested and the transmission channel for the paper to be tested are located in the paper box to be tested, and the paper transmission channel to be tested is located in front of the paper box to be tested. The front end of the test paper box includes a first baffle, and the front end of the paper transmission channel to be tested includes a second baffle; the sample capture slot is located above the test position, and the sample capture slot is used to place detection paper towels; the light source module is fixed on the first toilet. side, and located below the toilet seat; the light detection module is fixed on the second side of the toilet, and located below the toilet seat; the microprocessor is also used to determine the concentration of the component to be measured in the feces according to the detection data of the light detection module. The invention can improve the convenience of detection and speed up the progress of detection.

Description

technical field [0001] The invention relates to the field of excrement detection, in particular to a detection device and method based on photoelectric detection. Background technique [0002] Urine testing and stool testing are routine tests in modern clinical medicine, providing a basis for the diagnosis of certain diseases such as chronic kidney disease, diabetes, blood diseases, liver and gallbladder diseases, epidemic hemorrhagic fever, and colorectal cancer. Clinically, urine testing or stool testing is performed by dry chemical method. The test strip has multiple detection color blocks, which correspond to multiple detection indicators, such as protein in urine, pH, occult blood, urine specific gravity, microalbumin, creatinine Wait. The stool detection test paper is coated with a layer of tetramethylbenzidine chromogenic dye and a peroxide film, which will react with the hemoglobin in the stool to develop color. [0003] Dry chemical analysis technology refers to a...
