[0002] Non-invasive respiratory therapy is an important treatment for patients with early acute respiratory failure and chronic respiratory failure. Non-invasive respiratory therapy does not require tracheal intubation or incision. It only requires positive pressure mechanical ventilation connected through a nasal mask, face mask or laryngeal mask. It is currently widely used in the treatment of clinical respiratory diseases.

[0003] However, the existing masks have the following problems: the mask is generally not provided with a hole for inserting a gastric tube, and the non-invasive breathing mask needs to be pressed on the gastric tube and the gastric tube is inserted into the patient's face. On the one hand, this causes compression to the gastric tube, affecting the medium delivery of the gastric tube; on the other hand, the sealing of the mask is reduced, thereby reducing the effect of non-invasive breathing treatment.

The threaded groove on the connecting tube prevents the gastric tube from falling off, and it is also convenient to connect the gastric tube. The sealing ring arranged on the connecting tube can prevent the gastric tube from leaking the medium after connection, thereby ensuring the sealing of the gastric tube. By arranging a connecting tube and a connecting tube on the mask body, it is convenient to connect the gastric tube, and the sealing of the mask body is prevented from being reduced when the gastric tube is connected, thereby ensuring the treatment effect, and preventing the gastric tube from being squeezed and compressed, thereby ensuring the normal circulation of the medium in the gastric tube and ensuring the safety of the patient.

[0013] The beneficial effects of the utility model are:
