Abstract: Various implementations include an insufflation system for use with an endoscope. The insufflation system includes a housing, a CO2 system, a water system, a foot pedal, a control system, an aromatic dispersion system, an audio system, and a water tubing valve. Various implementations also include a more visible foot pedal, which is useful in difficult-to-see environments. In some implementations, a water tubing valve couples conduits from two water containers to the endoscope. In a first position, water flows only from a first water container. In a second position, water flows only from a second water container. The water tubing valve prevents water-flow from both of the first water container and the second water container to happen simultaneously. The water tubing valve allows for an operator to quickly switch a source of the water, thereby facilitating continuation of a procedure in a case that the first water container is fully depleted.
