Abstract

The invention discloses a double-airbag laryngeal mask airway for gastrointestinal endoscopy. The airway comprises a balloon, and the bottom of the balloon is communicated with a connecting pipe; thebottom of the connecting pipe is communicated with a mask bag which is provided with a breathing hole; a breather pipe is arranged at the bottom of the mask bag and penetrates through the mask bag tobe communicated with the breathing hole; the bottom of the breather pipe sleeves a mechanical end joint; an air passing pipe and an endoscope access pipe are arranged on the two sides of the breatherpipe respectively; a first passage with one end communicated with the outside is arranged in the balloon; a second passage communicated with the first passage is arranged in the connecting pipe; a guiding pipe communicated with the second passage is arranged in the mask bag; a first tract communicated with the guiding pipe is formed in the breather pipe, and the other end of the first tract is communicated with the endoscope access pipe.

Description

technical field [0001] The invention belongs to the field of medical equipment; in particular, it relates to a double-airbag laryngeal mask airway for gastroenteroscopy. Background technique [0002] Laryngeal mask airway, LMA, referred to as laryngeal mask, is composed of a ventilation catheter and a round inflatable air mask at the far end. It is implanted in the pharynx and injects an appropriate amount of air into the air mask to seal the larynx. , for ventilation. The laryngeal mask is beneficial to maintain the airway unobstructed, and does not require a special position. The operation is simple and quick, which can buy time and save the patient's life. [0003] The laryngeal mask is a medical device used for surgical anesthesia, rescue of critically ill patients, or other patients with assisted breathing to establish artificial airway ventilation, especially for patients with sudden cardiac arrest and difficulty in intubation. The areas of anesthesia, difficult airw...
