Abstract: Multi-parameters patient monitors are widely used in hospitals as medical device products, which have important clinical value. It expounds the core technologies of a miniature wearable multi-parameters patient monitor, and looks forward to its application prospects. In addition to traditional applications, when combined with a networked health service platforms, its applications will be greatly expanded in the context of big data and artificial intelligence technologies. The laboratory prototype of this product has been completed and has achieved the anticipative design goal.
