Problems solved by technology

The disadvantage is that this fastening method is cumbersome to operate, the connection is not stable, and it is easy to cause damage to the patient's facial skin or hair
[0004] Although the existing drainage laryngeal mask is easy to insert, it cannot perform endotracheal intubation through the laryngeal mask to complete the interchange between the endotracheal intubation and the laryngeal mask. Drainage of the esophagus

Abstract

The invention discloses a novel laryngeal mask. The novel laryngeal mask comprises an air bag, a breathing tube, a double-channel joint, an inflating tube, an indication air bag and a one-way valve, wherein an air inlet end of the breathing tube comprises a trachea channel and an esophagus drainage channel which are independent from each other; the trachea channel is divided into a trachea main channel and a trachea branch channel which are connected with each other; an epiglottis lifting table is arranged in front of the trachea main channel; and a wedge-shaped groove is formed in front of the epiglottis lifting table. The novel laryngeal mask is reasonable in design, meets clinical requirements and can be smoothly pressed in the throat of a patient; contents in the esophagus and the stomach of a patient can be drained; breathing of the patient in a surgery is guaranteed; using safety is improved; and tracheal intubation can be carried out through the laryngeal mask.

Description

Technical field [0001] The present invention relates to the technical field of tracheal intubation, in particular to a new type of laryngeal mask. Background technique [0002] In the existing laryngeal mask patents, the laryngeal mask includes parallel tracheal channels, esophageal drainage channels, and connecting arms. The connecting arms are in a vertical relationship with the tracheal channels and esophageal drainage channels, that is, the laryngeal mask connecting arm is located below the joint. After entering the human body, the fixed wings of the laryngeal mask are tightly fixed to the upper lip. During a long-term operation, the upper lip of the patient is easily damaged and ruptured due to the compression of the fixed wings. [0003] CN101203261A discloses a laryngeal mask airway device, which is provided with a baffle; after a few turns of gauze from the back of the patient's head, it is fastened by the baffle; or the patient's facial skin and the baffle are glued and fi...
