Detection device and method based on photoelectric detection

Abstract

The invention relates to a detection device and method based on photoelectric detection. The device is characterized in that a to-be-tested paper placing box is fixed at the rear part of a closestooland is positioned below a water tank; a to-be-tested paper box and a to-be-tested paper conveying channel are located in the to-be-tested paper placing box, the to-be-tested paper conveying channel islocated in front of the to-be-tested paper box, the front end of the to-be-tested paper box comprises a first baffle, and the front end of the to-be-tested paper conveying channel comprises a secondbaffle; a sample capturing groove is positioned above a test position and is used for placing a detection tissue; a light source module is fixed to the first side edge of the closestool and located below a closestool ring; an optical detection module is fixed on the second side edge of the closestool and is positioned below the closestool ring; and a microprocessor is also used for determining theconcentration of a to-be-detected component in excrement according to the detection data of the optical detection module. According to the device and method, the detection convenience can be improved, and the detection progress is accelerated.

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...
