In the course of processing, the processing mold of existing inflated type laryngeal mask and on-inflatable formula laryngeal mask is separate, and the versatility between two products is poor, and processing cost is high.
Summary of the invention
Based on this, the invention reside in the defective that overcomes prior art, a kind of laryngeal mask is provided, structure of the present invention can be used for inflated type laryngeal mask and on-inflatable formula laryngeal mask simultaneously, and highly versatile has reduced processing cost.
Its technical scheme is as follows:
A kind of laryngeal mask, comprise cover body and the flexible glue enclosure, the cover of cover body is provided with main blow vent, the both sides of cover body are provided with flank, first end at cover body is respectively equipped with main passage, air-filled pore, the first porus excretorius and the first negative pressure hole, the second end at cover body is respectively equipped with the second porus excretorius and the second negative pressure hole, and the first porus excretorius, the first negative pressure hole communicate with the second porus excretorius and the second negative pressure hole respectively, and main passage communicates with main blow vent; The flexible glue enclosure is enclosed within on the cover body, and the main blow vent of cover body, first end, the second end expose.
The below describes further technical scheme:
Described flank extends to first end, the second extreme direction simultaneously, and bonding with the described flexible glue enclosure, and forms inflatable chamber between cover body and the flexible glue enclosure, and described air-filled pore communicates with this inflatable chamber.
Dorsal part at described cover body is provided with aileron, and aileron is relative with described flank, and described inflatable chamber is between aileron and flank.
Be provided with excretory duct and negative tube in the axis of described cover body, described the first negative pressure hole, the second negative pressure hole communicate by negative tube, and described the first porus excretorius, the second porus excretorius communicate by excretory duct.
The below describes advantage or the principle of aforementioned techniques scheme:
1, this laryngeal mask has inflated type and two kinds of structures of on-inflatable formula, in use, cover body is packed in the flexible glue enclosure, if flank and the flexible glue enclosure of cover body is bonding, namely form inflatable chamber in the both sides of cover body, the laryngeal mask of this moment is the inflated type laryngeal mask, if the flank of cover body is not bonding with the flexible glue enclosure, then be on-inflatable formula laryngeal mask this moment.Adopt the laryngeal mask of this structure, highly versatile, processing cost is low.
2, the dorsal part at described cover body is provided with aileron, and flank is relative with aileron and form the outline supporting construction of cover body.
3, the cover body of this laryngeal mask and the flexible glue enclosure are colloidal silica, and its profile meets principle of human engineering, reduce the damage to human body.

The specific embodiment
The below is elaborated to embodiments of the invention:
Extremely shown in Figure 6 such as Fig. 1, a kind of laryngeal mask, comprise cover body 10 and the flexible glue enclosure 20, the cover of cover body 10 is provided with main blow vent 11, the both sides of cover body 10 are provided with flank 12, are respectively equipped with main passage, air-filled pore, the first porus excretorius and the first negative pressure hole at the first end 13 of cover body 10, are respectively equipped with the second porus excretorius and the second negative pressure hole at the second end 14 of cover body 10, the first porus excretorius, the first negative pressure hole communicate with the second porus excretorius and the second negative pressure hole respectively, and main passage communicates with main blow vent 11; The flexible glue enclosure 20 is enclosed within on the cover body 10, and the main blow vent 11 of cover body 10, first end 13, the second end 14 expose.
Wherein, described flank 12 extends to first end 13, the second end 14 directions simultaneously, and bonding with the described flexible glue enclosure 20, and forms inflatable chamber between cover body 10 and the flexible glue enclosure 20, and described air-filled pore communicates with this inflatable chamber.
Dorsal part at described cover body 10 is provided with aileron 15, and aileron 15 is relative with described flank 12, and described inflatable chamber is between aileron 15 and flank 12.
Be provided with excretory duct 16 and negative tube in the axis of described cover body 10, described the first negative pressure hole, the second negative pressure hole communicate by negative tube, and described the first porus excretorius, the second porus excretorius communicate by excretory duct 16.
