Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a tracheal intubation. Background Art

[0002] Tracheal intubation is often used during general anesthesia surgery, cardiopulmonary resuscitation, and the rescue of critically ill patients with respiratory dysfunction. It is mainly used to assist the patient's breathing, relieve airway obstruction, and aspirate airway secretions. When a patient needs general anesthesia surgery, or suddenly stops breathing, cannot breathe on their own, or has airway compression or excessive airway secretions that cannot be cleared on their own, resulting in airway obstruction, they may experience symptoms such as difficulty breathing, shortness of breath, cyanosis of the lips, dizziness, and fatigue. Timely tracheal intubation is necessary to assist breathing and relieve hypoxia.
