Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a non-invasive ventilator mask. Background Art

[0002] A non-invasive ventilator mask is a device used for non-invasive positive pressure ventilation. It connects the patient to the ventilator through non-invasive connection methods such as oral and nasal masks, full-face masks, nasal masks, nasal pillows, and helmets to perform positive pressure assisted ventilation. Non-invasive ventilation treatment does not require tracheal intubation or incision. It only requires positive pressure mechanical ventilation connected through these masks and other methods. It is widely used in clinical practice and has become an important means of treating respiratory failure and heart failure.

[0003] During the use of the currently used non-invasive breathing masks, since each person's facial features are different, the commonly used non-invasive curved masks cannot fit the face of each patient well, and air leakage may occur during actual use, especially when the non-invasive oronasal masks are used on the faces of thin elderly people. Because the elderly have fewer facial muscles and tooth loss, even the smallest model still has air leakage. Therefore, the present application provides a non-invasive ventilator mask to meet the needs. Utility Model Content
