Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a rapid detection kit for measles virus infection. Background Art

[0002] Measles is one of the most common acute respiratory infectious diseases in children. It is highly contagious and prone to epidemics in densely populated areas without universal vaccination, with an epidemic occurring about every 2 to 3 years. Clinically, symptoms such as fever, upper respiratory tract inflammation, and conjunctivitis may occur, and the main features are red maculopapular rashes on the skin, measles mucosal spots on the buccal mucosa, and residual pigmentation with bran-like desquamation after the rash subsides. In recent years, the World Health Organization Foundation for Innovative Diagnostics has confirmed the advantages of colloidal carbon as a signal label for immunochromatography. The visible light card reader scans the grayscale value of the colloidal carbon, and the concentration of the analyte can be quantified by the analysis software. Colloidal carbon has been widely used as a signal label at home and abroad to detect a variety of antigens.

[0003] The existing rapid measles virus infection test kit extract and test strip are matched. When in use, the extract may spill on the ground, and it is necessary to re-open a new one for use, which will cause a certain degree of waste. In addition, when in use, there are many people around, and the virus in the air will fly to the drip port, which may affect the accuracy of subsequent test results. Utility Model Content
