The connection portion 40 can be correspondingly connected to the connection assembly 3 to install the flexible contact member 4 in the annular opening 20. The connection assembly 3 includes an inflation adjustment member 30. An inflation interface 12 connected to the inflation adjustment member 30 is arranged on the mask body 1. The inflation adjustment member 30 accepts inflation or deflation from the inflation interface 12 and has an inflation state and a deflation state. In the inflation state, a part of the flexible contact member 4 extends out of the annular opening 20 to form an annular contact portion in contact with the patient's face. In the deflation state, the flexible contact member 4 is completely collected into the annular opening 20.

[0028] Specifically, an air supply connection mechanism 10 and a wearable member are provided on the mask body 1. The air supply connection mechanism 10 is connected to an oxygen delivery device to deliver oxygen into the mask body 1. The wearable member is used to wear the mask body 1 on the patient's face. This is the prior art and will not be elaborated. The side of the mask body 1 that is worn on the patient's face is the contact surface, and the shape of this contact surface is consistent with the shape of the patient's face, similar to a ring shape. For the convenience of description, it is called the annular contact surface 11. An annular pad 2 is provided on the annular contact surface 11. The shape of the annular pad 2 is consistent with the shape of the annular contact surface 11. The annular pad 2 is detachably installed on the annular contact surface 11. The annular pad 2 has elasticity. At the same time, an annular opening 20 is provided on the annular pad 2. The annular openings 20 are arranged in sequence along the circumference of the annular pad 2. A flexible contact member 4 is detachably provided in the annular opening 20.

The connecting component 3 includes an inflation adjusting part 30. During use, the inflation adjusting part 30 can be inflated or deflated. When the inflation adjusting part 30 is in the inflated state, the flexible contact part 4 extends out of the circular opening 20 to contact the patient's face. When the inflation adjusting part 30 is in the deflated state, the flexible contact part 4 is collected into the circular opening 20. In this way, when the patient wears the mask body 1 for a long time, the inflation adjusting part 30 can be inflated or deflated as needed, so that the parts of the patient's face in contact with the mask body 1 are sequentially changed, which can effectively prevent a certain part of the patient's face from being squeezed for a long time to cause pressure sores.
