For the simulation of upper and lower gastrointestinal hemorrhage, according to the idea of Hochberger, a perfusion system can be used to simulate arterial spurting bleedings in hollow gastrointestinal organs. This is achieved by perforating the organ wall externally with tubing connected to an artificial blood circuit. Cherry-red food colorant with the addition of 0.1% methylene blue is used as artificial blood. Varices can be simulated by submucosal injection of stained saline externally with a 23-gauge needle.
