An elderly man with weak sputum after a cerebral infarction also experienced the convenience of an airway clearance system at home. He suffered from severe pneumonia due to cerebral infarction, which resulted in immobility of his lower body and long-term bed rest. Before using the noninvasive sputum suction device of the airway clearance system, he needed to use the regular sputum suction device frequently and with poor results.

However, after using the QIjiA-Airway Clearance System noninvasive sputum aspirator (parameters +2.7, -4), he was able to smoothly expel large amounts of yellow sputum and his blood oxygen saturation increased from 91% to 95%. This change not only led to a significant improvement in his physical condition, but also made his home care much easier and more effective.

As an innovative medical device, the QIjiA-Airway Clearance System noninvasive sputum suction machine is gradually becoming an important tool for smooth sputum discharge in patients with severe diseases and neurological diseases. Through the above cases and data support, we can see the important role played by the sputum generator in improving the respiratory status of patients and improving the quality of life. In the future, with the continuous progress and innovation of medical technology, it is believed that the expectorating machine will bring Gospel and hope to more patients.
