Built-in endotracheal tube and laryngeal mask combined ventilation device for general anesthesia

Abstract

The invention discloses a combined air breather both of a built-in tracheal catheter and a laryngeal mask combined air breather for general anesthesia, which is characterized by comprising a laryngeal mask catheter and the a built-in tracheal catheter, wherein the built-in tracheal catheter is built-in in the laryngeal mask catheter, and a sealed pulling device is arranged between the built-in tracheal catheter and the laryngeal mask catheter; the air bags of the a laryngeal mask are respectively arranged at one end of the laryngeal mask catheter, and the built-in tracheal catheter is provided with an air bag of the a tracheal catheter; and the air bags of the laryngeal mask and the air bag of the tracheal catheter; are respectively communicated with an inflation valve of the laryngeal mask and an inflation valve of the tracheal catheter. According to the invention, a way of combining the built-in tracheal catheter and the laryngeal mask is adopted to solve the problems that the laryngeal mask is displaced when the patients are in the different positions or the position is changed in the surgery; and a way of installing and changing a cannula at any time under the proper condition is adopted to reduce ventilation obstacle and prevent airway hypersensitive reaction, haemodynamic fluctuation and resulting complications caused by the cannula of the tracheal catheter in the process of general anesthesia tube drawing. The combined air breather both of the built-in tracheal catheter and the laryngeal mask combined air breather for the general anesthesia provided by the invention is simple in structure, convenient to operate and obvious in using effect.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a built-in tracheal tube laryngeal mask combined ventilation device for general anesthesia. Background technique [0002] When performing general anesthesia surgery, it is necessary to provide assisted breathing for the patient to maintain the hemodynamic stability of the patient under general anesthesia. However, the current endotracheal tube and laryngeal mask breathing device are independent auxiliary breathing devices, and it is very inconvenient to replace each other. , and when switching the breathing mode, it is often easy to cause a series of complications caused by early extubation of the anesthesia and hypersensitivity of the airway. In addition, the old-style laryngeal mask is easy to shift and cause air leakage due to the different positions or changes of the patient's position during the operation, which makes the operation unpredictable and unfavorable.
