Inflation-free laryngeal mask tracheal tube

Abstract

The invention discloses an inflation-free laryngeal mask tracheal tube. The inflation-free laryngeal mask tracheal tube includes a main tube base, a ventilation tube and a cover cap, wherein the ventilation tube can be bent and is connected with the main tube base, and the cover cap covers the periphery of the main tube base and is closely cooperated with the ventilation tube, the cover cap has an adsorption end face, a first through hole is formed in the adsorption end face, a second through hole is also formed in the cover cap, the periphery of the ventilation tube is sleeved with the second through hole and closely cooperated with the ventilation tube, the main tube base is located between the first through hole and the second through hole, the cover cap is made from elastic memory materials, when the cover cap stretches into the throat, the adsorption end face is completely adsorbed onto the airway and is not inserted in the esophagus, and the ventilation tube is in seal communication with the airway. The adsorption end face is arranged on the cover cap and adsorbed mutually with the airway after being smeared with mucus, so that the cover cap and the airway are in a seamless seal state, the sealing effect is good, the cover cap does not invade the inside of the esophagus, independent management of the airway and the esophagus is achieved, the laryngeal mask tracheal tube is suitable for the physiological structures of easterners, and risks of regurgitation and aspiration are avoided.

Description

technical field [0001] The invention relates to a respiratory device, in particular to an air-free laryngeal mask endotracheal tube. Background technique [0002] The laryngeal mask endotracheal tube is a supraglottic device that can quickly and accurately align with the airway after being inserted into the throat. The laryngeal mask endotracheal tube was successfully developed in the mid-1980s and used clinically. It was introduced in China in the 1990s. At present, the use of the laryngeal mask endotracheal tube has made great progress, and the scope of application is becoming wider and wider. Then the laryngeal mask endotracheal tube used There are also certain disadvantages: that is, the laryngeal mask endotracheal tube is designed according to the physiological structure of Westerners, which is not suitable for the physiological structure of Easterners. When used, the cap of the laryngeal mask endotracheal tube often invades the esophagus, which not only reduces the Th...
