The invention relates to the technical field of health management systems, in particular to a TIPS postoperative patient home
nutrition system based on an LEARNS mode, and the
system comprises a
vein monitoring module, a
trend analysis module, a state evaluation module, an intervention suggestion module and a
nutrition adjustment module. According to the method, the
portal vein blood flow velocity and the daily
salt intake of the patient after the TIPS operation are continuously collected, the pre-intervention mean value is set as a
base line, the daily
salt intake deviation proportion is quantified, trend
correlation analysis is conducted in combination with the
blood flow velocity difference value, and the related mode of the
blood flow change and the
salt intake deviation is revealed; whether the
rehabilitation process is abnormal or not is comprehensively judged according to the trend change and a
recovery rate threshold value, the diet compliance degree is evaluated in combination with a set salt intake compliance interval, multi-dimensional
cross validation of physiological indexes and diet behaviors is achieved, the accuracy and real-time performance of evaluation are improved, targeted
intervention measures are matched according to different state combinations, and the evaluation accuracy is improved. Behaviors are guided or medication is adjusted in advance, the
rehabilitation risk is reduced, and the
home management effect is improved.
