Haier Biosciences comprehensively promotes the integration and innovation of IoT technology and low-temperature storage technology. Traditional storage devices are upgraded to IoT scenarios to meet the iterative needs of users such as clinical blood use, vaccination, and biobank applications, and build an IoT technology ecosystem. The blood network scenario program is based on the "Cloud Wing" Internet of Things blood cold storage box network device, which links blood collection, blood delivery and clinical blood use scenarios to achieve the full traceability of blood information from "blood donor" to "blood user". The vaccine network scenario plan is based on the "Haile Miao" vaccination box network device, linking the vaccination entrance and exit scenes, realizing the traceability of the last mile of vaccination, and the transparent and visible matching of the vaccine to ensure the safety of the vaccine. Vaccine Network has launched more than 500 vaccination sites across the country, and will build the country’s first fully-covered smart city vaccine network in Shenzhen, and enter 78 countries and regions including participating countries of the “Belt and Road”. 120,000 Internet of Things vaccination box-net devices have protected the health of 200 million children worldwide. The biological sample network scenario plan is based on the "cloud core" IoT ultra-low temperature storage box network device, which links sample collection, storage, and application scenarios to achieve cloud-network collaboration, accurate sample positioning, one-click access, and information traceability to promote samples Management change.
