Description

Respiratory Therapy Mask

technical field

The present invention relates to a mask, especially a respiratory treatment mask, which can be connected to a breathing tube of a breathing device, and can make the breathing tube perform universal rotation, so that no matter where the patient is relative to the breathing device, the breathing tube can Turn to the proper direction to avoid excessive bending of the breathing tube, resulting in unsmooth gas supply, or even causing mask air leakage due to pulling.
