technical field

The utility model relates to the field of medical equipment, in particular to an oral sputum collecting device under the condition of non-invasive breathing support.

Background technique

In the current field of non-invasive respiratory support technology for critically ill breathing, it mainly relies on non-invasive respiratory support ventilation under the oronasal mask. This ventilation method is effective for patients with mild respiratory failure. Establish a channel between the trachea and prevent air leakage, so as to ensure the smooth progress of positive pressure ventilation. However, during the whole cycle of inhalation and exhalation of the patient, the ventilator circuit, the oronasal mask, the patient's oral cavity, nasal cavity and pharynx are all affected. There is a high positive pressure, so that the mucus in the patient's alveoli, small airways and trachea cannot be smoothly discharged through the pharynx and mouth during the patient's expiratory phase, resulting in the accumulation of sputum in the trachea and lungs. The formation of phlegm plugs can cause airway blockage, leading to complications such as suffocation and infection. Clinically, it mainly relies on guiding cough and suction tube to suck sputum through the oropharynx, but the effect is very unsatisfactory.
