Abstract:

BACKGROUND: Blood and blood products are different from general drugs, they need different storage temperatures for preservation of biological activity when they are in in vitro environment. In order to ensure safe, effective and reliable quality, blood cold chain is necessary to avoid a fact that too high or low temperature influences the quality of blood or blood products.
OBJECTIVE: Based on the existing problems of present domestic blood cold chain management, this paper proposed an application of distributed wireless multi-point temperature measuring system.
METHODS: The system used the technology of 1-wire digital sensor, wireless communication and single-chip microcomputer in the management. It can intelligently identify the abnormal temperature fluctuation and alarm. The PC monitoring software was designed by using Visual C# 2008, which can monitor many slave systems simultaneously.
RESULTS AND CONCLUSION: Repeated experiments show that the system operates stably and has good reliability.
