1. A medical tube for delivering a respiratory gas to a subject, wherein the medical tube is in fluid connection with a user interface and a respiratory device, the medical tube comprises:
a tubular body for delivering the respiratory gas from the respiratory device to the user interface;
a first rib helically extending along the outer surface of the tubular body, in which the first rib comprises:
at least one wire disposed within the first rib and is configured to heat the respiratory gas within the tubular body, and/or to detect the temperature, humidity, flow rate or pressure of the respiratory gas;
a membrane encapsulating the first rib thereby generating a helical space along the outer surface of the tubular body; wherein the helical space serves as an aeration channel allowing the exhaled gas of the subject to pass through, and the respiratory gas delivered from respiratory device does not pass through the helical space; wherein the helical space is configured to monitor the temperature, pressure, flow rate or humidity of the exhaled gas of the subject; and
a joint tube disposed at one of the free ends or the outer surface of the tubular body, wherein the joint tube is in fluid connection with the helical space.
