Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to an airway clearing device for critical care respiratory support. Background Art
[0002] In the critical care department, the most common medical treatment is respiratory management and respiratory support for patients with acute respiratory insufficiency and other various acute and critical patients. Airway patency is usually reflected by the flow of respiratory gases. The gas flow is proportional to the airway diameter. The larger the airway diameter, the smoother the flow. Conversely, if the airway is spasmodic, narrowed or blocked, the airway diameter becomes smaller and the gas flow slows down. However, the ventilators currently used must ensure that the airway is unobstructed to work effectively.
[0003] When rescuing patients with respiratory failure, not every doctor will perform endotracheal intubation. Therefore, an easy-to-operate airway clearance device is needed to provide emergency mechanical ventilation for patients with respiratory failure. The device must have both the operability of an oropharyngeal airway and the reliability of artificial ventilation of an endotracheal intubation. The existing oropharyngeal airway structure is relatively simple and cannot be adjusted according to the length and shortness of the patient's oral activity. It is easy to fall off or be swallowed by the patient, posing a hidden danger to the patient's safety. Emergency ventilation with a mask alone often cannot effectively open the airway. For this reason, we combined the advantages of a mask and an oropharyngeal airway and proposed an airway clearance device for critical care respiratory support to solve the above problems.
