Cup-shaped airway capable of being sealed to aditus laryngis peripheral tissue

Abstract

The invention provides a medical intubation type, non-inflatable and cup-shaped airway attached to the aditus laryngis. The shape of a cup is matched with the anatomical structure of the periphery of the aditus laryngis, and the cup is closely attached to the peripheral tissue through a sealing ring. An epiglottis support is arranged at the part, corresponding to the epiglottis, in the aditus laryngis cup; a tongue root seat is arranged in the position, corresponding to the tongue root, of a main airway; a C-shaped stomach tube groove is formed in the outer side wall of the main airway, and when used, a stomach tube is separated from the main airway as required. The cup is made of a soft artificial rubber material on the basis that the cup is better matched with the anatomical structure of the periphery of the aditus laryngis, the sealing ring is additionally arranged, better airway sealing performance is realized, and soft tissue surrounding the aditus laryngis cannot be pressed or damaged.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a cup-type ventilator at the mouth of the throat used in ventilation therapy. . Background technique [0002] During anesthesia and first aid, the patient loses spontaneous breathing, and artificial ventilation is required for the patient. In the current known technology, artificial ventilation is mainly completed by two kinds of airway products: the lower airway (tube) at the throat and the upper airway at the throat. [0003] Existing upper throat airway can be divided into two types: inflatable bag type and non-inflatable bag type two kinds of throat upper airway. The non-inflatable airway can be further divided into soft rubber type and hard rubber type supralaryngoscopic airway. [0004] The sublaryngoscopic airway is called the stable airway because the ventilation method is to insert the endotracheal tube into the main trachea located under the laryngeal openin...

AI Technical Summary

Problems solved by technology

Poor airtightness can lead to airway "leakage" during ventilation, which directly affects the effect of ventilation therapy. Severe air leakage will cause ineffective ventilation and bring huge risks to patients;

[0006] 2. During the use of the existing upper airway at the throat, if the "epiglottis turns back" under the action of the ventilation airflow during ventilation, the phenomenon of epiglottis blocking the airway will occur, affecting the smoothness of the airway and even airway obstruction ;

[0007] 3. Under general anesthesia, the tongue body becomes abnormally soft and "paralyzed" towards the root of the tongue, which will affect the physical stability of the airway during use;

[0009] To sum up: the existing upper laryngeal airway has the problem of ventilation airtightness; the inflatable upper laryngeal airway compresses the surrounding tissue nerves to cause postoperative sore throat and other complications; hard plastic upper laryngeal ventilation The problem of damage to the pharynx and buccal caused by insertion; the risk of airway obstruction caused by epiglottis reflexion during ventilation; stability problems during use; the problem of the third-generation upper airway exiting the throat and retaining the gastric tube
