AI Technical Summary

⚠Technical Problem

Existing blood routine testing instruments are large, expensive, and complex in structure, making them difficult to carry. Furthermore, problems in the testing process can affect testing efficiency and accuracy.

⚗Method used

Design a microfluidic chip that integrates a first detection system, a second detection system, and a third detection system. Employ an integrated and miniaturized microfluidic chip with independent detection systems and drive channels. It is suitable for optical detection, impedance detection, and impedance counting of blood samples. The driver drives the liquid to move within the detection system through the drive channels.

🎯Benefits of technology

It achieves miniaturization, portability and low cost of microfluidic chips. Samples can be directly discarded after testing to reduce the risk of contamination. The independent detection system avoids interference, reduces the impact on detection efficiency, and enables accurate quantification, reducing sample and reagent waste.
