Abstract: A method for determining emptying of upper gastrointestinal tract includes the steps of: providing an upper gastrointestinal monitoring system including a detecting device, a transmission module, a signal processing device and a signal display; acquiring a time signal of RGB three primary colors of an upper gastrointestinal tract image with the detecting device; transmitting the time signal of RGB three primary colors by the transmission module to the signal processing device; calculating an intensity ratio of the time signal of RGB three primary color; evaluating the upper gastrointestinal emptying according to the intensity ratio of the time signal of RGB three primary color; and displaying the evaluation result on the signal display.

Abstract: A method for determining upper gastrointestinal bleeding course includes the steps of: providing an upper gastrointestinal bleeding monitoring system including a bleeding detecting device, a transmission module, a signal processing device and a signal display; acquiring a time signal of RGB three primary colors of an upper gastrointestinal tract image with the bleeding detecting device; transmitting the time signal of RGB three primary colors by the transmission module to the signal processing device; calculating an intensity ratio of the time signal of RGB three primary color; evaluating the upper gastrointestinal bleeding course according to the intensity ratio of the time signal of RGB three primary color; and displaying the evaluation result on the signal display.
