Problems solved by technology

[0003] Currently, gastroscopes / bronchoscopes / esophagoscopes currently available in the market vary in size. For example, the diameter of an esophagoscope is 17mm, and the length of the hard tube end exceeds 40mm. Similar to the above-mentioned laryngeal masks for diagnosis and treatment, the scope of use is limited: On the one hand: painless The size of the lumen of the gastroscope is too small, so that the gastroscope, bronchofiberscope or esophagoscope cannot enter the lumen; As a result, the gastroscope or bronchoscope or esophagoscope is stuck in the lumen and cannot move
Inserting with force may cause damage to the laryngeal mask
At the same time, in emergency situations such as first aid, switching to a different size or choosing the wrong size of the laryngeal mask will cause serious consequences such as missing the best treatment time

Abstract

The invention discloses a laryngeal mask capable of dilating and used for endoscope diagnosis and treatment, and relates to the technical field of medical instruments. The laryngeal mask comprises a mask bag and an air passage catheter, the mask bag is fixedly connected to the air passage catheter, the air passage catheter comprises an aerating air passage, an endoscope channel and an air fillingtube channel, an aerating inlet, an endoscope inlet and an air filling tube inlet are located in the end, away from the mask bag, of the air passage catheter, the mask bag comprises a basic body and an air bag connected to the basic body, the air bag surrounds the edge of the basic body in an annular shape, the air filling tube inlet is connected to the air bag, the endoscope outlet is connected to the lower surface of the basic body and points to the front side of the basic body, a dilating opening which extends from the endoscope inlet to an endoscope outlet is formed in the back face of theendoscope channel, and the air bag becomes smaller easily and gradually from the rear side of the basic body to the front side. The laryngeal mask can effectively dilate and deform so that an endoscope can be inserted.
