    摘要: A catheter device according to one aspect of the present invention includes: a tube to be inserted into a body; a light emitting unit, which is provided on a distal end side of the tube, and includes an infrared light emitting element configured to emit infrared light for verifying a position of the tube; a power supply line configured to supply electric power to the infrared light emitting element; and a conduction detection unit including a visible light emitting element configured to notify a conduction state between the power supply line and the infrared light emitting element by means of visible light. With the catheter device, operation of the light emitting unit can be visually checked before inserting the tube.
