Description

Technical Field

[0001] The utility model relates to the technical field of ventilation treatment equipment, in particular to a continuous positive pressure ventilation mask. Background Art

[0002] Ventilation therapy equipment is an important medical device in modern medicine. It is mainly used for the treatment of various respiratory diseases or sleep breathing disorders with continuous positive airway pressure ventilation, which can assist in the treatment of sleep apnea. In ventilation therapy, in order to provide therapeutic gas to the user, it is usually necessary to wear a mask on the user's head. The existing ventilation masks currently have facial silicone pads that do not fit the position of the human face. During the oxygen supply process of the ventilator, oxygen is easily leaked from the bridge of the nose and the cheeks. The connection between the frame of the ventilation mask and the facial silicone pad is not tight, which is also prone to air leakage, thereby reducing the amount of oxygen inhaled by the user and endangering the user's health. In addition, the existing ventilation masks are worn for a long time and are prone to pressure sores on the face, causing discomfort to the wearer. Therefore, a continuous positive airway pressure mask is needed. Utility Model Content
