Generally, the most effective way to treat obstructive sleep apnea syndrome is to use a continuous positive airway pressure (CPAP), which means that the patient wears a device connected to a pump during sleep. For the breathing mask, the pump is controlled by a host that can adjust the airflow pressure to continuously push air into the airway to generate a continuous positive-pressure airflow to keep the patient's airway that would otherwise collapse during sleep unobstructed.

However, in order to maintain the above-mentioned positive pressure state, the breathing mask must fit tightly around the patient's mouth and nose to avoid air leakage and insufficient air pressure. However, if the breathing mask fits too much pressure around the mouth and nose, it will cause discomfort , so currently there is a breathing mask 9 as shown in Figure 1, which uses the design that the pressure is distributed by the forehead and around the mouth and nose to reduce the patient's discomfort. It includes a body unit 91, an air supply tube 92, and a connecting piece 93. A forehead support pad 94 and a headband 95. The body unit 91 is provided with a buffer pad 911 covering the patient's mouth and nose, and an opening 912 is formed on the opposite side to connect the air supply tube 92, and the air supply tube 92 is connected to a pump (not shown) to provide continuous positive pressure airflow.

Then tighten and fix with Velcro 952 respectively, so that the body unit 91 can be tightly covered around the mouth and nose, and at the same time, the forehead support pad 94 is pressed against the patient's forehead, so that the forehead can be used to share the pressure and reduce the pressure around the mouth and nose burden.

However, because there are many differences in the facial shape of the patient, and the above-mentioned connector 93 cannot be adjusted and changed, it often happens that the buffer pad 911 and the forehead support pad 94 cannot be fitted to the mouth and nose and the forehead at the same time, so that the pressure cannot be adjusted. Spread the burden. In addition, the above-mentioned headband 95 must pass through the upper fixing groove 941 and the lower fixing groove 913 to be fixed. Such a slotting action is not easy to complete quickly, especially when the patient sleeps until midnight and goes to the toilet. If you put it on, you will have to turn on the light, which is not only troublesome, but also may completely eliminate drowsiness, so it still needs to be improved.
