The invention relates to a dual-channel joint tracheal tube respiration system which is characterized by comprising a tracheal tube, a breathing filter, an L-shaped joint, a Y-shaped joint and an anaesthesia machine connecting tube, wherein the tracheal tube comprises a guide tube, a patient insertion end, an airbag, a gas tube and an inflation valve; the airbag is arranged on the patient insertion end; the gas tube is communicated with an inflation chamber of the guide tube; the tracheal tube is communicated with the L-shaped joint through the guide tube; the L-shaped joint is connected withthe Y-shaped joint; the Y-shaped joint is connected with the anaesthesia machine connecting tube; the guide tube joint and the L-shaped joint are at least provided with two chambers; and the Y-shapedjoint is of a detachable structure in which at least two chambers are formed. The dual-channel joint tracheal tube respiration system has the advantages of eliminating a mechanical dead space, effectively relieving respiratory depression caused by anesthetics, improving respiratory functions of the patients, correcting acid-base imbalance of the body of the patients and further greatly improving the vital signs. The respiration system particularly has significances in aspects such as elimination of the mechanical dead space of infants and critical patients or during prolonged operations, ICU management and the like.
