Abstract
A combined system of a concealed closed tracheoscope and an artificial airway breathing circuit includes an artificial airway breathing tubing and a tracheoscope. The artificial airway breathing tubing includes an inhalation circuit and an exhalation circuit that are connected through a connecting tube. The tracheoscope includes a handle portion and an insertion portion connected to the handle portion. The tracheoscope handle portion wraps around a section of the exhalation circuit. The tracheoscope insertion portion is hidden in the extendable breathing circuit, which extends and retracts to make the tracheoscope insertion portion advance or retreat in a closed condition. The tracheoscope handle function assembly cleverly wraps around the surface of the breathing circuit tubing, organically combining the functions of the tracheoscope handle and the breathing circuit. Meanwhile, the tube interface can be cleaned to keep the tracheoscope clean and unobstructed, such that the service life of the tracheoscope can be extended.
