1. A medical tube position confirmation system for confirming the position of a medical tube that is used to supply nutrients to the interior of a living body of a patient while an end portion thereof is inserted into the stomach, the system comprising:
a light guide that is configured to guide light entering through an incident end portion so that the light exits through an exit end portion, and is configured to be insertable into the medical tube so that the exit end portion is disposed in the stomach;
a light source that is optically connected to the incident end portion of the light guide and emits light containing wavelengths that pass through a living body;
an imaging unit for capturing an image of the living body on the basis of at least the light that exits through the exit end portion of the light guide and passes through the living body, wherein the imaging unit is disposed outside of the living body; and
a control unit that controls intensity of light emitted by the light source,
wherein the control unit controls the intensity of the light emitted by the light source within an intensity range that equals or exceeds a first intensity specific to the patient and is lower than a second intensity specific to the patient.
