Description

technical field [0001] The invention relates to the technical field of vital sign monitoring, in particular to a novel optical fiber interference type vital sign monitoring device and method. Background technique [0002] Most of the vital sign monitors currently on the market are invasive or wearable, and these detection solutions may have a certain impact on people's normal rest. In addition, in order to avoid cross-infection, traditional ECG monitoring basically uses disposable electrodes, which are difficult to recycle. [0003] In the monitoring of vital signs in special environments, such as nuclear magnetic resonance environments, traditional electronic monitoring may be helpless against strong electromagnetic interference. [0004] In summary, traditional vital signs monitoring products have the following deficiencies: [0005] First: Intrusive or wearable monitoring; [0006] Second: It cannot cope with the monitoring in the environment of strong electromagnetic ...
