Abstract

The invention discloses an accurate-positioned double-tube laryngeal mask, which comprises a cuff, an airway tube, an inflation tube and an indicating balloon, wherein the front end of the cuff is provided with a drainage hole, and the cuff is also connected with an independent drainage tube. The front end of the drainage tube is connected with the drainage hole, and the periphery of the drainage hole is provided with a LED (Light-Emitting Diode) lamp along the circumference of the drainage hole. As the independent drainage tube is arranged, the accurate-positioned double-tube laryngeal mask can carry out manual suction and negative pressure suction for stomach contents. The LED lamp arranged at the front end of the cuff plays an indication role and helps a doctor accurately insert into the laryngo-pharynx part of a patient, the condition of poor air seal due to operation errors is prevented, and the air seal of the laryngo-pharynx part is enhanced.

Description

technical field [0001] The invention discloses a double-pipe laryngeal mask capable of accurate positioning, which belongs to the field of medical instruments. Background technique [0002] At present, the LMA laryngeal mask in the hospital is mainly used for artificial ventilation during surgical general anesthesia, first aid and resuscitation; during general anesthesia, the doctor inserts the laryngeal mask into the throat of the patient through the mouth to establish an artificial airway. During the operation of the patient, the effective airway is maintained to ensure a safe and smooth operation process; among them, the LMA-ProSeal gastric tube drainage type laryngeal mask is the third generation laryngeal mask, and the laryngeal mask has double tubes, one tube can be ventilated, and the other tube can be inserted gastric tube drainage. [0003] Its disadvantages are: when the laryngeal mask is inserted into the patient's pharynx, the doctor's precise operation is requi...
