Fish mouth type laryngeal mask trachea duct capable of performing rinsing with three cavities

Abstract

The invention discloses a fish mouth type laryngeal mask trachea duct capable of performing rinsing with three cavities. The fish mouth type laryngeal mask trachea duct capable of performing rinsing with three cavities comprises a hood body, wherein a respiration chamber which communicates with a respiratory tract and a digestion chamber which communicates with a digestive tract are arranged in the hood body; the digestion chamber is provided with a digestion opening through which the digestion chamber communicates with the digestive tract; the periphery wall of the digestion chamber is gradually contracted from one end away from the digestion opening to the digestion opening; a plurality of protrusions are arranged at the edges of the digestion opening, and can be mutually closed becauseof surrounding extruding pressure in the process that the fish mouth type laryngeal mask trachea duct capable of performing rinsing with three cavities is inserted into the throat part, so that the digestion opening is contracted. Through the adoption of the technical scheme of the fish mouth type laryngeal mask trachea duct capable of performing rinsing with three cavities disclosed by the invention, an opening corresponding to the digestive tract can be quickly and accurately aligned to the digestive tract to be inserted, and the operation time is shortened.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a three-chamber flushable fish mouth type laryngeal mask airway catheter. Background technique [0002] The laryngeal mask is an artificial airway device that allows the patient to maintain spontaneous breathing and implement positive pressure ventilation during surgery. During use, the laryngeal mask needs to be inserted into the patient's body through the throat. Since the details of the throat cannot be seen during the operation, the operator needs to rely on hand feeling and experience to insert, making it difficult to align the opening of the end of the laryngeal mask corresponding to the digestive tract. , the respiratory tract and digestive tract cannot be effectively isolated, and the insertion position needs to be adjusted repeatedly, which prolongs the operation time and increases the risk of treatment. Contents of the invention [0003] The main purpose of t...
