[0002] A blood type detection card is a small detection device used to quickly and simply detect an individual's blood type. It is usually a small card or test strip pre - set with specific reagents or markers that can undergo specific biochemical reactions with a blood sample, thereby judging the blood type information of the detected blood according to the reaction results. A microfluidic platform is an experimental platform based on microfluidic technology for precisely controlling the liquid flow, mixing, distribution, and detection reaction process in microfluids.

[0003] However, most traditional blood type detection cards based on microfluidic platforms need to be placed in a specific placement box for safe carrying. It is impossible to carry the blood type detection card alone safely, which increases the burden and inconvenience of carrying. Moreover, if the placement box is forgotten to be carried or accidentally lost, the blood type detection card may be damaged or lost due to the external environment.
