The use of laryngeal masks has been greatly advanced at present, and the scope of application is becoming wider and wider. The laryngeal mask is applied to general anesthesia operation and is used for establishing a safe airway. In the anesthetic operation using the laryngeal mask, some patients need to insert an endoscope such as a bronchofiberscope into the airway and the lung for observation or auxiliary operation, so that the bronchofiberscope needs to be smoothly inserted into the laryngeal mask; the common double-channel bronchofiberscope laryngeal mask comprises a cavity for passing a gastric tube and a cavity for inserting a bronchofiberscope; when using ordinary binary channels bronchofiberscope laryngeal mask in the operation in-process, often appear that the bronchofiberscope can't aim at the glottis, lead to the bronchofiberscope can not fine get into the air flue, and ordinary single channel laryngeal mask can not effectually prevent to flow back, mistake inhale, and need be equipped with the bite-block when using, increase medical personnel's work load.
The Chinese patent document with the publication number of CN204951869U discloses a laryngeal mask for painless gastroscopy diagnosis and treatment, which comprises a mask bag and an airway catheter, wherein the mask bag is fixedly connected with the airway catheter, the airway catheter forms a ventilation airway, a gastroscope or bronchofiberscope channel and an inflation tube channel, and two ports of the ventilation airway are a ventilation inlet and a ventilation outlet respectively; the two ports of the gastroscope or the bronchofiberscope channel are respectively a gastroscope or a bronchofiberscope channel inlet and a gastroscope or a bronchofiberscope channel outlet; the two ports of the inflation tube channel are respectively an inflation inlet and an inflation outlet, and the inflation outlet is communicated with the cover bag; one end of the airway catheter with the gastroscope or bronchofiberscope channel outlet is fixedly connected with the cover bag, the front end of the cover bag is provided with a notch, the gastroscope or bronchofiberscope channel outlet is arranged at the notch of the cover bag, and the gastroscope or bronchofiberscope channel outlet is contracted in the front end face of the cover bag for a certain interval.
The laryngeal mask is easy to cause that the bronchoscope is not easy to align with the glottis in the using process, so that the bronchoscope cannot well enter the airway.
The Chinese patent literature with the publication number of CN105561454 discloses a drainage type bronchofiberscope laryngeal mask, which comprises a main pipe, a bronchofiberscope channel cavity, a ventilation cavity, an inflation cavity and a drainage cavity are arranged in the main pipe, one end of the inflation cavity, which is positioned at the outer side, is connected with an inflation joint, a first sealing bag and a second sealing bag are arranged at different positions outside the main pipe, and the first sealing bag and the second sealing bag are communicated with the inflation cavity.

In order to make the structure inside the cover bag simpler and more stable, one groove wall of the guide groove is also used as the wall of the stomach tube channel, and at the moment, the part of the stomach tube channel in the cover bag and the inner bottom surface of the cover bag are of an integrated structure.
In order to enable a larger space to be arranged in the cover bag, and simultaneously avoid backflow and aspiration, the side wall of the cover bag gradually closes up upwards along the edge of the bottom of the cover bag to form an air guide hole of the cover bag; the thickness of the side wall of the cover bag gradually decreases towards the direction of the air vent, and the bottom and the side wall of the cover bag form a liquid storage cavity.
The traditional cover bag adopts a side wall air bag structure generally, and can be more attached to pharyngeal cavity tissues during positive pressure ventilation, so that reinforcement sealing is realized. The clinical sealing effect is achieved, and high pressure is required, so that the throat pain of a patient after operation is often caused; when the inflation pressure is low, gas leakage often occurs, so that ventilation failure or aspiration occurs in the mouth water flow air inlet channel.
In the invention, the side wall with a solid structure is preferably adopted, the self-sealing design is adopted, and the thickness of the side wall at the position close to the bottom of the cover bag is thicker and is 4-8 mm; the thickness of the air guide hole is thinner and is 0.5-3 mm.
The side wall of the solid structure is adopted, so that the volume formed by surrounding between the inner bottom surface and the side wall of the mask bag is greatly increased, the inner bottom surface and the side wall of the front end part of the mask bag form a main liquid storage cavity vertically downwards in the use process of the laryngeal mask, and once backflow occurs and liquid flows into the air guide hole on the front surface of the mask bag, the liquid storage cavity can be used for storing the backflow liquid so as to prevent the backflow liquid from flowing into the air passage.
Normally, the inflation-free cover bag structure can well solve the reflux problem by being matched with the liquid storage cavity. Because various emergency conditions can occur in the medical operation, the back of the cover bag is also provided with a special anti-reflux channel in order to further enhance the anti-reflux effect. Even if other measures for preventing backflow are invalid, the backflow prevention channel can enable backflow liquid to be discharged out of the body through the oral cavity rapidly.
In order to further improve the practicability of the laryngeal mask, the laryngeal mask can be suitable for more devices, and the inner diameter of the air guide pipeline is 5-18 mm.
The cover bag is made of silica gel material with excellent elasticity and is soft. The front end of the cover bag is designed into an arc which is more in line with the physiological structure of the human body, so that the esophagus can be better closed, and reflux is prevented.
Compared with the prior art, the invention has the following beneficial effects:
1. According to the invention, the guide groove with a certain length is arranged in the inner cavity of the mask bag aiming at the function of the laryngeal mask requiring the bronchofiberscope, and the guide groove is used as a bronchofiberscope channel, so that the glottis can be accurately found by the bronchofiberscope and can be smoothly inserted when the bronchofiberscope is used.
2. The cover bag is an inflation-free cover bag, adopts the side wall with a solid structure, has the thick lower end and the thin upper end, and when in use, the thin bag part at the upper end of the side wall is tightly attached to the periphery of the throat to achieve the self-sealing function; meanwhile, compared with the air bag structure, the side wall of the solid structure greatly increases the volume of the inner cavity of the cover bag to form a liquid storage cavity, once backflow occurs and liquid flows into the air guide hole on the front surface of the cover bag, the liquid storage cavity can be used for storing the backflow liquid so as to prevent the backflow liquid from flowing into the air passage.
