## 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.

## Claims

### Claim 1

An insufflation system, the system comprising:
a housing defining an inlet CO2 port and an outlet CO2 port;
a CO2 conduit disposed within the housing that couples the inlet CO2 port and the outlet CO2 port;
an endoscope water pump coupled to the housing;
a foot pedal coupled to a control system, the control system being electrically coupled to the endoscope water pump and the housing, and the foot pedal being compressible, wherein compression of the foot pedal causes generation of an electrical signal that causes the endoscope water pump to turn on or off, and the foot pedal has an outer surface that is at least partially illuminated;
a valve configured for selecting a water container from two or more water containers for providing water to an endoscope; and
an aromatic dispersion system, wherein the housing defines an aromatic outlet being coupled with the aromatic dispersion system, the aromatic dispersion system comprising an aroma source receptacle and an evaporative diffuser for diffusing an aroma source in the aroma source receptacle, wherein the diffused aroma source flows through the aromatic outlet to an environment outside of the housing.

### Claim 2 (depends on 1)

The insufflation system of claim 1, wherein at least one of the two or more water containers is coupled to the housing.

### Claim 3 (depends on 1)

The insufflation system of claim 1, the system further comprising:
a CO2 valve in fluid communication with the outlet CO2 port; and
at least one circuit board disposed within the housing, the at least one circuit board being electrically coupled to the CO2 valve and the endoscope water pump to control a flow rate of CO2 through the CO2 valve and water flow through the endoscope water pump.

### Claim 4 (depends on 1)

The insufflation system of claim 1, wherein at least a portion of the aromatic dispersion system is disposable within the housing.
