Description

Technical Field

[0001] This utility model belongs to the field of biomedical technology, and in particular relates to a multi-function combined detection card. Background Technology

[0002] The multi-test card is a highly efficient and convenient in vitro diagnostic tool, primarily used for reproductive health testing and drug abuse screening. It includes simultaneous testing of sex hormone levels, semi-quantitative HCG detection, LH peak detection, and drug testing. It can simultaneously detect multiple sex hormone indicators and can also semi-quantitatively measure human chorionic gonadotropin (HCG) and luteinizing hormone (LH) levels to help predict early pregnancy and ovulation cycles. It can also simultaneously detect multiple common abused drugs. Utilizing immunochromatography, the card provides results within 1-10 minutes using a urine sample. It is widely used in clinical laboratories, health check centers, and drug rehabilitation facilities, providing reliable preliminary test results for hormone level monitoring, early pregnancy diagnosis, ovulation prediction, and drug abuse screening.

[0003] Traditional test strips have the following problems: the observation window is assembled from the outside of the product, which causes shadows to be reflected on the test strip when observing the test results, and there are also step-like shadows around the observation window, affecting the interpretation of the results; after the product is soaked in urine and the test strip is picked up and placed flat on the table, urine sample will accumulate at the sample-dipping end, causing two situations: first, excess urine will overflow the test strip and contaminate areas outside the detection area; second, a large amount of urine will flow upwards quickly, causing membrane flushing and affecting the test results.

[0004] Therefore, a multi-factor combined detection card needs to be designed to solve the above problems. Utility Model Content
