Problems solved by technology

When the handheld urine analyzer detects the tested paper, the test paper is placed on the transmission device, and then transported to the optical path detection device. When the test paper is placed, the position of the test paper may not be accurate. The test paper is soaked with The color block of urine may not be aligned with the optical path detection device, or the light is only irradiated to the edge of the color block, which will cause errors in the detection results

Description

Technical field [0001] The invention relates to a liquid analysis device, in particular to a handheld urine analyzer, which belongs to the field of medical equipment. Background technique [0002] Urine analyzer is a common medical analysis instrument, commonly used in hospitals and various medical institutions. The basic working principle of the urine analyzer is to use light to irradiate a urine test strip that has been dipped in the urine. The light intensity of the reflected light of the wet and chemically reacted test strip, thereby obtaining the analysis result. [0003] For test strips dedicated to urine analyzers, the test strips are generally divided into 8, 10, and 11 items according to the number of test strips, and detect protein (PRO), glucose (GLU), PH, and ketones in urine respectively. Body (KET), bilirubin (BIL), urobilinogen (UGB), occult blood (BLD), nitrite (NIT), white blood cells (LEU), specific gravity (SG) and vitamin C (Vc) and other components. The measu...
