At present, the laryngeal masks on the market are all inserted through the mouth. Some patients with small mouth opening, trismus, and oral deformities cannot be inserted smoothly. Displacement, patients are not easy to tolerate, prone to irritability, breathlessness, and even laryngospasm. Most laryngeal masks cannot effectively isolate the respiratory tract from the digestive tract, and are prone to flatulence or aspiration.

Utility model content:

In view of the above problems, the technical problem to be solved by the utility model is to provide a laryngeal mask for transnasal and esophageal occlusion.

The utility model relates to a nasal and esophageal blocking laryngeal mask, which comprises a tube body, an anesthesia machine interface, a throat balloon inflation port, an esophageal balloon inflation port, a laryngeal mask vent, a throat inflation balloon, an indicator line, Guide tube, esophageal balloon, spiral steel wire, one end of the tube body is provided with an anesthesia machine interface, the anesthesia machine interface is connected with the breathing circuit of the anesthesia machine, and the two sides of one end of the tube body are respectively connected with the throat balloon inflation port and the esophagus balloon inflation port The other end of the tube body is provided with a laryngeal mask vent, and the laryngeal mask vent is connected with the tube body, one side of the laryngeal mask vent is provided with a laryngeal inflatable balloon, and the outer wall of the tube body is provided with an indicator line , the two ends of the indicator line are respectively connected to the anesthesia machine interface and the middle of the laryngeal mask vent, the other end of the tube is connected to the top of the guide tube, and is connected to the esophageal balloon through the guide tube, and the tube is provided with a spiral steel wire.

Preferably, the tube body is made of silica gel or soft plastic material, which can reduce the damage caused by nasal cavity insertion.

Preferably, the indicator line is convenient for people to adjust the direction of the laryngeal mask in time, so as to better ensure the patency of the airway.

Preferably, the guide tube is convenient for people to insert into the esophagus smoothly.

As a preference, the spiral steel wire has a supporting function to ensure the smoothness of the tube body and avoid the compression of tissues, organs and balloons after inflation.

Beneficial effects of the utility model: it uses a single-chamber ventilation tube to be inserted from the nasal cavity, which is more smooth and convenient, and is especially suitable for patients with shallow general anesthesia, small mouth opening, trismus or oral deformity. The tube body is formed, and the spiral steel wire is set in the tube body, which not only has good patient tolerance after insertion, but also is not easy to shift and is easy to fix. By setting the esophageal air bag and the laryngeal air bag, the digestive tract can be effectively isolated and sealed. to avoid flatulence and reflux.
