Supraglottic device capable of positive pressure ventilation and non-invasive tube intubation

Abstract

The invention discloses a supraglottic device capable of positive pressure ventilation and non-invasive tube intubation, wherein the supraglottic device comprises a ventilation pipeline, a drainage pipeline system, a pressure regulating plate and an air bag. The pressure regulating plate can make the device inserted in an appropriate position to adapt to personal difference, and adjusts the heightof a distal opening of the ventilation pipeline elevated by air inflation of the air bag so as to make the air flow of the ventilation pipeline directly align to a glottis. Meanwhile, a central sulcus in a downstream section of a suppression plate coincides with a central sulcus in the bottom wall of a distal section of the ventilation pipeline so as to guide a bougic to enter the glottis. The left part and the right part of the air bag after inflation form a closed state with surrounding tissues and elevate a tongue root together with the top wall of the distal section of the ventilation pipeline; at the same time, the middle part of the air bag after inflation elevates the opening of the distal end of the ventilation pipeline. A pressure regulating plate included angle adapts to the distance between the glottic opening and the pharynx and larynx wall of different individuals. The drainage pipeline system also comprises an esophageal drainage pipe which can drain the upper part of the esophagus and a pharyngeal drainage pipe that can drain the pharynx. An expansion part of the esophageal drainage pipe can form a closed state with the upper esophageal opening.

Description

technical field [0001] The invention relates to the technical field of medical devices, and relates to a supraglottic device capable of positive pressure ventilation and non-invasive intubation. And the invention provides a way for diagnosing and treating vocal cord and tracheal diseases near the glottis. Background technique [0002] For a long time, when a patient needs positive pressure ventilation, it is necessary to insert a tracheal tube, and then use a ventilator or artificial positive pressure ventilation to push various required medical gases into the lungs for ventilation. The endotracheal tube is made of relatively hard plastic. Once it touches the lining of the trachea, it may cause bronchospasm, infection, or damage to the lining of the trachea, causing tracheal stenosis. It may also cause damage to the vocal cords and glottis. Therefore, the air bag at the far end of the anesthesia endotracheal catheter in small infants is easy to damage the delicate inner muc...
