Description

Technical Field

[0001] The utility model relates to the technical field of breathing masks, in particular to a non-invasive ventilation mask that is convenient for patients with indwelling gastric tubes to use. Background Art

[0002] The edge of an ordinary mask in contact with the face is smooth, which is better for patients without a gastric tube. However, for patients with an indwelling nasogastric tube or nasointestinal tube, when using an ordinary mask to administer pressurized oxygen, due to its flat contact surface, a triangle is formed where it contacts the gastric tube, i.e., the two sides of the gastric tube, the skin and the mask. This triangle makes it impossible to achieve a seal, and ultimately leads to a large amount of air leakage, which greatly reduces the effectiveness of non-invasive respiratory ventilation and often leads to the failure of non-invasive mechanical ventilation, and then has to be switched to endotracheal intubation and invasive mechanical ventilation. For some patients who could have been treated with non-invasive mechanical ventilation, invasive mechanical ventilation will undoubtedly increase the patient's pain, increase medical expenses, and even affect their prognosis. For this reason, we propose a non-invasive ventilation mask that is convenient for patients with indwelling gastric tubes. Utility Model Content

The adapting convex pad is integrally formed with the wearing mask pad itself.

[0005] Preferably, the internal space of the adapting convex pad forms a three-quarter circular hollow cavity. When the external trachea is inserted into the interior of the adapting convex pad, the inner side of the adapting convex pad is located outside the trachea in a fitted and wrapped state.

[0006] Preferably, the mask pad itself has a deformable property and is filled with gas.

[0008] Preferably, the front and rear inner sides of the adapting convex pad are both connected with inner pressure pads, and the inner pressure pads are hollow pads with a three-quarter circular area;

[0009] Furthermore, when an external trachea is inserted into the interior of the adapting convex pad, the inner pressure pad inside the adapting convex pad is located on the periphery of the trachea in a squeeze-fitting and sealing state.
