[0023] The existing mask breathing system includes a pressure support device (such as a ventilator), a ventilation pipeline, and a breathing mask. The pressure support device delivers breathable gas into the breathing mask through the ventilation pipeline, thereby providing respiratory treatment for the wearer of the mask.

[0024] The breathing mask is generally composed of a cushion assembly, a headband assembly, an elbow, and a frame assembly with a support bar. The cushion assembly includes a face contact unit and a support unit adjacent to the face unit, forming a cavity that can accommodate the nose or nose and mouth of the wearer. The frame assembly is connected to the cushion and the elbow, and the headband device is connected to the support bar to fix the mask device to the face of the wearer, forming a sealed cavity. When the pressure support device is ventilated, the face contact unit of the cushion is blown towards the face of the mask wearer by the pressure in the mask cavity, and the support unit connected to the face contact unit provides a support force. The headband assembly is fixed to form a good seal between the face of the patient and the mask, thereby ensuring the stability of the pressure in the cavity. The headband assembly can be a soft and adjustable strap that fixes the mask to the face of the wearer. The other end of the elbow is rotatably connected to the frame assembly, and the other end of the elbow is connected to the ventilation pipeline that delivers breathable gas.

[0025] The support bar is a semi-rigid structure with a certain bending deformation effect, which can provide stability and support for the mask during the wearing of the mask by the user, so as to reduce the restraint and compression of the face during the stretching process of the headband traction. In order to reduce the compression and scratching of the face by the support bar, a flexible buffer pad is provided between the support bar and the face of the user to buffer and protect the cheeks of the user.
