XUZHOU LIHUA ELECTRONIC TECHNOLOGY DEVELOPMENT CO., LIMITED  is a specialized manufacturer of microcirculation instruments. We have inherited and innovated the traditional products of the former Xuzhou Optical Instrument Factory, which produced China's first microcirculation microscope and won the Leipzig Gold Award at an international fair. We are also the formulator of the GB standard for microcirculation microscopes that is still in use today.
On our new journey, we have absorbed advanced foreign technologies, overcome technical barriers, and successfully localized the Sidestream Dark Field (SDF) microcirculation microscope (sublingual microcirculation | sublingual microcirculation imaging | sublingual microcirculation imaging system | microcirculation microscope | SDF sidestream dark field microscope | SDF parallax dark field). We have also tackled major defects in foreign counterparts, solving issues such as uncontrollable pressure, significant image drift, and operator fatigue.
In our efforts to improve SDF instruments, we have obtained 2 Chinese invention patents, 1 US patent, 1 European patent, and 7 utility model patents, as well as 1 software copyright. We have also won third prizes at the China Medical Technology Innovation Competition in 2020 and 2024.
Importantly, we have proposed a new sepsis pathogenesis theory and identified its broad clinical applications. We have established a threshold index for high-speed blood flow and implemented the relevant algorithm in our software, enhancing the instrument's auxiliary diagnostic role in critical - care and emergency settings.
From 2024 to 2025, we achieved breakthroughs in software algorithms, using optimized algorithms to enable the ultra - early and early detection of septic infections and post - surgery infections, thereby reducing infection - related mortality. Our vision is to lower the global sepsis mortality rate to below 5% and safeguard against post - major - surgery infection deaths.
