Abstract: An upper gastrointestinal bleeding monitoring system includes a detection device and a signal processing device to determine bleeding condition of an upper gastrointestinal tract by using relation of time and intensity ratios of RGB three primary colors. The detecting device is placed to the upper gastrointestinal tract of a patient via his/her mouth or nasal passage and then stay the upper gastrointestinal tract for several days for detection of bleeding. The signal processing device may receive and display signal from the detection device to help medical professionals check if bleeding occurs in an upper gastrointestinal tract. Moreover, a procedure of determination of bleeding in an upper gastrointestinal tract with the upper gastrointestinal bleeding monitoring system is described.

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.
