Technical Field

[0001] The utility model relates to the technical field of breathing masks. Specifically, the utility model relates to improving the structure of an elbow pipe assembly, so that the elbow pipe of the breathing mask can rotate in multiple directions, and thus the breathing mask can be adjusted better according to the use scenario. Background Art

[0002] A breathing mask is the main device for assisting patients with dyspnea in positive pressure ventilation, and is also often used by doctors in clinical operations or treatments to assist patients in breathing or to enable patients to inhale drugs that need to be inhaled through breathing. It is a very important medical auxiliary device.
