The application discloses a postoperative gastrointestinal
motility closed-loop
management system and belongs to the technical field of postoperative gastrointestinal
motility nursing, which comprises the following: a
wireless distributed sensing node attached to key acupoints on the
abdomen for collecting borborygmus, gastrointestinal slow wave, abdominal tension and IMU motion posture; an
edge computing control terminal running an adaptive multi-
modal fusion
algorithm, calculating a gastrointestinal
motility index MI(t) by dynamically updating weights through Kalman filtering or variational
Bayesian inference; a two-stage safety execution module containing
software logic fusing (stopping when the
algorithm judges an
abnormality) and hardware physical fusing (
MOSFET relay forced power-off); and a cloud monitoring platform supporting remote
visual monitoring, data tracing, OTA upgrading and adopting AES-256 hardware
encryption; the
system realizes a four-layer closed-loop architecture from sensing, decision-making, execution and monitoring. The application significantly shortens the postoperative
gastrointestinal function recovery time and reduces the incidence of complications through non-invasive multi-
modal monitoring and closed-loop feedback.
