The colloidal gold immune layer analyzer is an important medical auxiliary clinical diagnostic equipment. It tests the strength of the CT line through reflectance spectroscopy. It is mainly used in hospitals to detect serum, plasma, blood, and urine samples in vitro. It can also be used to detect biochemical cards. Pesticide residues, water quality problems, clinical diseases, animal diseases and other harmful residues made of gold standard cards and liquid titration modules. In the early stage of design, the designer has undergone sufficient market research, combined with design needs, aesthetic needs, emotional needs, and aesthetic needs to determine the design direction, from appearance design, structural design, material selection, color matching, process processing, man-machine operation, etc. Design innovation in many aspects. In terms of appearance design, the shape is novel and unique, the size is small, the details are paid attention to, and the surface process is exquisite; the color is mainly warm, with white and black, blue and black, gold and black matching each other, giving people optimistic and sunny visual effects; Pay attention to man-machine processing, fully consider the use needs of medical staff, improve the simplicity of use and the safety of operation; high-definition display design, the measured data can be clearly seen. The switch is located at the bottom of the display screen, which is very eye-catching, simple to operate, and fast and accurate to measure. The left chassis of the colloidal gold immune layer analyzer has a charging socket, which can be used not only with electricity but also with batteries, which is very convenient. The product function adopts the combination of colloidal gold immune layer technology and photoelectric quantitative detection technology, mainly composed of main control processor, optical detection system, signal processing unit, capacitive touch screen, network module, micro printer, memory, other communication interface and shell composition, supporting special kit, timely detection, assist in clinical diagnosis of brain tissue damage, stroke, heart failure, renal damage, acute and chronic kidney disease, early detection and early treatment of diseases such as cardiorenal syndrome.
