| 1. A gas supply system comprising:
a first gas supply unit configured to supply a first gas into a body;
a second gas supply unit configured to supply a second gas into the body;
a selection unit configured to send an instruction to select any one of the first gas and the second gas; and
a controller electrically connected to the first gas supply unit, the second gas supply unit, and the selection unit and operative
to control at least one of the first gas supply unit and the second gas supply unit to selectively insufflate any one of the
first gas and the second gas into the body based on the instruction sent from the selection unit, the controller operable
to control the insufflation such that any one of the first gas and the second gas is provided to at least one cavity in the
body to cause the cavity to distend for treatment or diagnosis in the at least one cavity,
wherein the second gas supply unit comprises:
a gas-supply source for the second gas;
a delivery member coupled to the gas-supply source and configured to deliver the second gas into the body, part of the delivery
member serving as a gas delivery channel of an observation device, part of the observation device being inserted into the
body to observe an interior of the body; and
an illumination light source operable to output illumination light, wherein the second gas supply unit serves as an illumination
light supply unit to supply the illumination light outputted from the light source through the delivery member into the observation
device, and wherein the illumination light source comprises:
a lamp for outputting the illumination light; and
a light source controller,
wherein the gas-supply source is installed in the illumination light source, and the light source controller is configured
to control an amount of the second gas to be supplied from the gas-supply source, and to control an operating state of the
lamp.
