The invention provides an intelligent infusion monitoring method and
system based on multi-
sensor fusion, and relates to the technical field of intelligent infusion monitoring. The method comprises the following steps: acquiring infusion process data through a visual sensor, a weight sensor and an
infrared sensor; aligning the
time sequence labels and synchronously generating a fusion
data stream; extracting a liquid level height characteristic, a
weight change rate and a real-time dripping speed value, and carrying out dynamic weighting calculation; acquiring infusion doctor's advice data of a
hospital information system, and extracting a preset dripping speed range and a total liquid amount; calculating the residual
infusion time based on the weighted data and the total liquid amount correlation; when the weighted real-time dripping speed value deviates from a preset range, the weighted
weight change rate is not matched with the liquid level height trend or the dripping speed pulse
signal is lost, an early warning instruction is generated; and the remaining time and the early warning state are visually displayed at the nurse
station terminal. Through multi-
source data fusion and
cross validation, the problems of incomplete monitoring,
time sequence dislocation and early warning
lag are solved, and infusion safety and
management efficiency are improved.
