Described Novel multifunctional laryngeal mask, it is characterised in that four-way connection is divided into outer lumen and interior tube chamber, in wherein, tube chamber is irregular ellipse, interior tube chamber lacuna entirety is increased, thus reducing aeration resistance, lumen diameter can hold common tracheal intubation, makes to intubate resistance less.
Described Novel multifunctional laryngeal mask, it is characterised in that fixing stomach tube chamber is positioned at side wing type fixed handle side, overall through laryngeal mask.
Described Novel multifunctional laryngeal mask, it is characterised in that stomach tube lock chamber arrival end has one projecting in side wing type fixed handle plane, when fixing laryngeal mask, it is possible to be effectively prevented the fixing stomach tube chamber of adhesive tape blocking, simultaneously facilitate assignment test.
Described Novel multifunctional laryngeal mask, it is characterised in that breather entirety is in slightly larger than 95 �� of bendings, and pipe shaft is flat ellipse so that laryngeal mask is easy to, through its inner chamber circulation of qi promoting cannula, also comply with the physiological structure of human oral cavity, pharyngeal cavity.
Described Novel multifunctional laryngeal mask, it is characterized in that the middle part of breather remote outlet bottom surface and left side are that wedge raises shape, make endotracheal tube lift 30 degree of angles from direction, center after this outlet to advance, it is simple to it accurately enters glottis, and its outlet shapes fades to circle.
Described Novel multifunctional laryngeal mask, it is characterised in that breather Distal Right has a drain lacuna, in anti-" D " shape.
Described Novel multifunctional laryngeal mask, it is characterised in that drain lacuna is through in the same plane with the cover end.
Described Novel multifunctional laryngeal mask, it is characterized in that a bridge being integrally formed with drain lacuna above the right side of breather remote outlet bottom surface, it is connected with venting tube outlet, not only improve the secretions absorbing cover bottom, more play the effect of epiglottis fence, when epiglottis cover outlet, this drainage lumens serves the effect preventing airflow obstruction.
Described Novel multifunctional laryngeal mask, it is characterized in that the channel distal end outlet of fixing stomach tube chamber is beyond cover capsule far-end 1��2mm, and the port of export is inclined plane shape so that stomach tube can enter esophagus accurately and rapidly, it is easy to tip and inserts esophagus upper end, and reduce the most advanced and sophisticated damage to tissue.
Patent of the present invention compared with prior art has simple in construction, easy to use, can well make laryngeal mask combine with tracheal intubation, stomach tube.

Detailed description of the invention
Novel multifunctional laryngeal mask, including cover capsule 1, breather 2, joint 3, gas tube 4, pilot balloon 5, check valve 6, fixing stomach tube chamber 7, it is characterized in that joint 3 is made up of four-way connection 3-1 and side wing type fixed handle 3-2 two parts, side wing type fixed handle 3-2 is positioned at four-way connection 3-1 both sides, by side wing type fixed handle 3-2, laryngeal mask is fixed on corners of the mouth both sides, thus avoid the upper lower lip of compressing when fixing in the past, joint 3 entirety is connected with breather 2, four-way connection 3-1 is divided into outer lumen 3-1-1 and interior tube chamber 3-1-2, wherein interior tube chamber 3-1-2 is irregular ellipse, interior tube chamber 3-1-2 lacuna entirety is increased, thus reducing aeration resistance, lumen diameter can hold common tracheal intubation, fixing stomach tube chamber 7 is positioned at side wing type fixed handle 3-2 side, overall through laryngeal mask, breather 2 is overall in 90 �� of bendings, pipe shaft is flat ellipse, laryngeal mask is made more to meet the physiological structure of human body oropharynx and throat, resistance during insertion reduces, convenient, fast, on the left of breather 2 remote outlet, place raises shape in wedge 2-1, guide effect is formed when tracheal intubation, make tracheal intubation quick, accurately enter air flue, breather 2 Distal Right has a drain lacuna 2-2, in half " C " shape, drain lacuna 2-2 is through in the same plane with the cover end, a bridge 8 is integrally formed with drain lacuna 2-2 above the right side of breather 2 remote outlet bottom surface, it is connected with breather 2 outlet, not only improve the secretions absorbing cover bottom, more play the effect of epiglottis fence, when epiglottis cover outlet, drain lacuna 2-2 serves the effect preventing airflow obstruction, fixing stomach tube chamber 7 channel distal end is beyond cover capsule 1 far-end 1��2mm, and the port of export is inclined plane shape, make the stomach tube can be accurate, it is rapidly introduced into esophagus.
Time clinical specifically used, insertion end is inserted patient airway place, run through gas tube 4 to inflate, cover capsule 1 is made to open by breather 2, during prolonged operations, it is trapped in drain lacuna 2-2 owing to having juice inside air flue and esophagus, at this moment suction catheter can be passed through by its sucking-off, thus prevent internal inflammations and the generation inhaled by mistake, insert tracheal intubation also by breather 2 and maintain ventilation, art can be passed through stomach tube lock chamber 7 and insert stomach tube or drainage tube drains gastric juice stomach function regulating and backflows thing, thus avoiding the thing entrance air flue that backflows, it is prevented that flatulence.
