Though the two-tube laryngeal mask of prior art has the attraction function, the ability of its attraction is very limited, and is effective to the attraction of liquid, and solid and thickness object are not then had effect.
Summary of the invention
The purpose of this utility model is defective and the deficiency that overcomes prior art, a kind of new multi-functional laryngeal mask is provided, multi-functional laryngeal mask of the present utility model can prevent that gastric content from backflowing, mistake is inhaled, prevent that gas from entering gastric, prevent displacement, also having the effect that can gastric attracts simultaneously, is to guarantee under the patient safety situation better ventilation apparatus.
Multi-functional laryngeal mask of the present utility model improves at the defective that prior art exists, multi-functional laryngeal mask of the present utility model is on the basis of present two-tube laryngeal mask, esophageal catheter to prior art prolongs, establish the endotracheal tube of band air bag as esophageal catheter at the front end of two-tube laryngeal mask stomach tube suction catheter, this esophageal catheter adopts and the preparation of endotracheal tube identical materials, and its performance of this esophageal catheter and soft or hard degree are also similar in appearance to endotracheal tube.
Particularly, multi-functional laryngeal mask of the present utility model comprises aerating gasbag (3) and suction catheter (9), it is characterized in that, also comprises esophageal catheter (6) and joint (8); Establish air bag (7) on the described esophageal catheter (6), this air bag is by charge valve (1) inflation, and described aerating gasbag (3) connects charge valve (2), and described suction catheter (9) is established the connector (4) of esophageal catheter and the connector (5) of laryngeal mask; Described joint (8) is located on suction catheter (9) sidewall.
In this utility model, esophageal catheter (6) front end is established aerating gasbag (7) and charge valve (1), and described charge valve (1) is connected on the esophageal catheter (6) by connecting duct 1 (10), this charge valve (1) control aerating gasbag (7) inflation, venting; The length of described aerating gasbag (7) is identical with the length of 5-7 endotracheal tube, and the diameter of inflation back aerating gasbag (7) is 3-5cm.
In this utility model, charge valve (2) is connected on the aerating gasbag (3) by connecting duct 2 (11); Described suction catheter (9) is established the connector (4) of esophageal catheter and the connector (5) of laryngeal mask, establish joint (8) on the sidewall of suction catheter (9), this joint (8) connects anesthetic machine or respirator corrugated tubing, joint (8) and anesthetic machine or respirator corrugated tubing coupling.
In this utility model, set the esophageal catheter (6) that can inflate can insert during use in the esophagus, can guarantee that laryngeal mask can not move forward and backward and blocks glottis; The set aerating gasbag (7) of esophageal catheter (6) can prevent that laryngeal mask from moving up and down, and can prevent that gastric content from backflowing, mistake sucks lung, and prevents that gas from entering gastric, also has the function that gastric attracts simultaneously.This utility model can directly be ventilated in the conduit insertion patient trachea with front end when the patient of treatment difficult intubation, actively treats effectively.
Multi-functional laryngeal mask of the present utility model is through clinic trial, and the result shows, except the scope of application of general laryngeal mask, also is fit to full gastropathy people's relevant treatment; This Multifunction laryngeal mask is wider, safer than the prior art laryngeal mask scope of application, can get a desired effect, and clinical preferably use value is arranged.
For the ease of understanding, multi-functional laryngeal mask of the present utility model is described in detail below by the drawings and specific embodiments.It needs to be noted that specific embodiments and the drawings only are in order to illustrate, obviously those skilled in the art can illustrate according to this paper, and this utility model is carried out various corrections or change, and these corrections and changing also will be included within this utility model scope.
