The stomach tube drainage cavity and the laryngeal aspiration cavity are respectively positioned at two sides of the ventilation cavity; the back of the cover body is provided with a liquid storage guide groove at the back of the cover body, and the liquid storage guide groove at the back of the cover body is communicated with the throat suction cavity.

Wherein, the bottom bag of the cover body is made of elastomer material.

And an inlet of the liquid storage guide groove at the back of the cover body is arranged below the liquid storage guide groove at the back of the cover body.

And the secretion or blood at the throat part can be collected to the inlet of the liquid storage guide groove at the back of the cover body through the liquid storage guide groove at the back of the cover body, and finally is sucked and discharged out of the body through the throat suction cavity.

Wherein, the cover body ventilation extension groove extends to the bottom of the front end of the cover body. Prevent the blockage of the vent hole caused by the enlargement or the narrowing of the throat part of partial patients.

The cross section of the ventilation extension groove of the cover body is wide in front and narrow in back, and is approximately in a U-shaped groove shape.

Wherein, the front end of the cover body is provided with a through hole which is communicated with the gastric tube drainage cavity.

Wherein, a stomach tube can be inserted into the stomach tube drainage cavity.

The wall thickness of the bag at the bottom of the cover body adopts gradual change design, so that the bottom of the cover body is adaptive to the periphery of the air passage opening to achieve the effect of sealing the air passage.

Wherein, the machine end connector and the airway tube are assembled and connected into a whole, and the machine end connector can be connected with a breathing machine to meet the normal operation ventilation.

Compared with the prior art, the utility model discloses an outstanding effect lies in:

adopt the utility model discloses a multichannel abnormal shape laryngeal mask endotracheal tube, normal operation ventilation process accessible drainage chamber is said and is inserted the stomach tube and get into the esophagus and carry out the esophagus drainage, and the throat attracts the chamber to say and can insert at any time and attract the pipe and carry out the attraction of substances such as throat position secretion or blood. The utility model discloses increased cover body back stock solution guiding groove and can store partial throat position secretion or blood earlier, the guiding groove that link up completely at the back simultaneously can collect throat position secretion or blood to the export that the throat portion attracted the chamber way, attracts to get rid of through attracting the chamber and gets rid of extracorporeally, reduces gathering of throat position secretion or blood as far as to reach and prevent that the operation process from flowing backward and inhale the air flue by patient's mistake and produce the risk, the security is higher.

The following description and specific examples will further explain the multi-channel abnormal laryngeal mask endotracheal tube of the present invention.
