Abstract

The utility model relates to a double-channel plastic laryngeal mask comprising an air guiding tube embedded with a helix linear on tube wall and a remote inflatable cover of egg shape. The inflatable cover is communicated with the air guiding tube. The inflatable cover is composed of an air cell base, a hollow cylinder air cell, and a backpack connected with it. The inflatable cover is also designed with a gullet tube in parallel with the air guiding tube. One end of the gullet tube pulls through the backpack and forms the gullet tube outlet at the top of the air cell. The middle of the air guiding tube and the gullet tube is designed with a dismantling bite rim. The air cell is connected with the inflatable tube, the inflation indication cell, and the single-way valve. Its advantages are: the addition of the gullet channel on the base of the laryngeal mask function, it can not only ensure the establishment of artificial air channel, but also meet the need of gastric juice excretion and nutrient supplementation. The laryngeal mask can be positioned into patient throat conveniently. With the small stimulation, the utility model can not only be used for normal operating patients, but also apply to patients with the difficulty of inserting windpipe or those in cardiopulmonary resuscitation rescue as the urgent air channel processing device.
