State the attraction interface 73 that the outer tail end of suction tube 72 connection is provided for being connected with medical negative pressure suction pipe.By the attraction during use
Interface 73 connects with medical negative pressure suction.Under suction function, the class Ring like suction disc face 5 of the bionical bottom of cushion 4 of leech is adsorbed
In the throat wall mucomembranous surface that surround encloses outdoors, the bionical cushion 4 of leech of softness is set to deform and can be close to what surround sound enclosed outdoors
Throat wall mucous membrane, so as to which the inner space of cover body 3 be isolated with the free surrounding space of mouth and throat.It is described in order to reach this effect
The material hardness that the bionical cushion 4 of leech and class Ring like suction disc face 5 use is preferably smaller than the hardness of human body mucous membrane, including silica gel, solidifying
Glue etc..
When it is implemented, the class Ring like suction disc face 5 is preferably provided in 4 times category annular major axis of the bionical cushion of leech
Line position, the width in class Ring like suction disc face 5 are less than the width of the bionical class annular lower surface of cushion 4 of leech, and the bionical cushion 4 of leech
Class annular lower surface top layer of outside indwelling proper width in class Ring like suction disc face 5 is not configured to class Ring like suction disc face 5.This
Sample, class Ring like suction disc face 5 is attracted to the throat wall mucomembranous surface that surround encloses outdoors during actual use, and cushion venting cavity 41 is located at
Glottis front position, the bionical lower surface of cushion 4 of leech cushion top layer of outside indwelling in class Ring like suction disc face 5, which can be pulled, to be sticked
In the throat wall mucomembranous surface for the outer edge of class Ring like suction disc face 5 that surround encloses outdoors, good sealing function is played.
When it is implemented, class Ring like suction disc face 5 and human body bottleneck throat surface texture compactness are higher, the pressure of negative pressure is got over
Greatly, class Ring like suction disc face 5 is more soft, and the bionical cushion 4 of leech can be just that laryngeal mask cover body 3 provides more superior sealing.Specifically
During implementation, the hardness of the bionical material of 4 class Ring like suction disc face of cushion 5 of leech is preferably smaller than the hardness of human body mucous membrane, including silicon
Glue, gel etc..So, under negative-pressure adsorption, the deformation of class Ring like suction disc face 5 of the bionical cushion 4 of leech is adsorbed on throat wall, and
It is not that the deformation lifting of throat wall mucous membrane abuts in the surface of class Ring like suction disc face 5, avoids negative pressure from causing to damage to throat wall mucous membrane.
During actual fabrication, for the ease of the bionical cushion 4 of the leech is bonded with cover body 3, on the bionical cushion 4 of leech

Class ring-shaped depression groove is put, then the assembling of cellular annular circle body 50 that profile size matches is fixed in class ring-shaped depression groove.Institute
Suction tube 71 in setting in the inner ring connected in star outer ring edge of the bionical bottom of cushion 4 of leech is stated to connect with the sealing of outer suction tube 72,
Conducting path is provided for negative pressure.
As shown in Fig. 4, Fig. 6 and Fig. 7, the sealing of the bionical offer of cushion 4 of leech, the class when being used further to improve
The inner ring edge part of Ring like suction disc face 5 sets the inner ring diaphragm seal circle 51 of soft quality class annular.
In class Ring like suction disc face 5, inner ring edge part sets the meaning of the inner ring diaphragm seal circle 51 of soft quality class annular to be：Make
Used time, if there is gap in the inner edge edge of class Ring like suction disc face 5 and mucosa, because mechanical ventilation is positive airway pressure and class is annular
The inside of sucker face 5 is negative pressure, and the liquidity preference of gas is to be flowed out of laryngeal mask cover body 3 to the side of class Ring like suction disc face 5.Now
Under the effect of the pressure differential of ventilation malleation and the negative pressure of class Ring like suction disc face 5, the inner ring of the internal edge of class Ring like suction disc face 5 is arranged on
The deformation closure of diaphragm seal circle 51 at the gap opening that class Ring like suction disc face 5 and mucosa occur, make in the cover body 3 of laryngeal mask to
The gas leakage in class Ring like suction disc face 5 does not occur still to be just released from.The premise that certain inner ring diaphragm seal circle 51 works is laryngeal mask
The location-appropriate of patient's pharyngolaryngeal cavity, and laryngeal mask fixation is safe, this is to lift easily in current laryngeal mask technology.
The effect that the inner ring diaphragm seal circle 51 improves laryngeal mask airway sealing depends on：The thickness of inner ring diaphragm seal circle 51
Degree, the material softness degree of inner ring diaphragm seal circle 51, the width of inner ring diaphragm seal circle 51.Inner ring diaphragm seal 51 thickness of circle are thinner, material
Material is more soft, and width is wider to provide more superior sealing effectiveness.But inner ring diaphragm seal 51 thickness of circle are thinner, and material is more soft
Soft, width is wider, and the 51 easier curling of inner ring diaphragm seal circle, causes sealing property to decline during actual use.During specific manufacture
The parameters of inner ring diaphragm seal circle 51 can be adjusted according to actual experiment effect, the sealing effectiveness of inner ring diaphragm seal circle 51 is reached most
It is good.
Similarly, it is the sealing that the bionical cushion 4 of leech provides when further raising uses, outside the class Ring like suction disc face 5
Enclose the outer ring diaphragm seal circle 52 that edge part sets soft quality class annular.
The outer ring edge part of class Ring like suction disc face 5 sets the meaning of the outer ring diaphragm seal circle 52 of soft quality class annular to be：
In use, when if gap occur in the outer rim edge of class Ring like suction disc face 5 and mucosa, because the pressure of oropharynx cavum laryngis is equal to air
Pressure, and the inside of class Ring like suction disc face 5 is negative pressure, the liquidity preference of gas is to the side of class Ring like suction disc face 5 out of oropharynx cavum laryngis
Flowing.Now under the effect of the pressure differential of atmospheric pressure and the negative pressure of class Ring like suction disc face 5, the external edge of class Ring like suction disc face 5 is arranged on
The deformation of outer ring diaphragm seal circle 52 closure of edge makes oropharynx larynx at the gap opening that class Ring like suction disc face 5 and mucosa occur
Gas leakage of the intracavitary to class Ring like suction disc face 5 does not occur still to be just released from.Similarly, what intraoral secretion and alimentary canal backflowed disappears
Change liquid to be also just blocked before class Ring like suction disc face 5 is flowed into.
The sealing of substantially ventilation of gas leakage of the gas of oropharynx cavum laryngis to class Ring like suction disc face 5 to laryngeal mask has no dry
Disturb, but gas leakage reveals the negative pressure in class Ring like suction disc face 5, glues the throat wall that class Ring like suction disc face 5 is enclosed outdoors with surround
Film surface sticks degree decline, and then declines class Ring like suction disc face 5 and the sealing of laryngeal mask cover body 3, gas leakage is caused larynx
Cover ventilation failure Probability increase.
But gap opening of the mouth intracavity liquid through class Ring like suction disc face 5 and mucosa enters class Ring like suction disc face 5, and passes through
Interior suction tube 71, outer suction tube 72 and the attraction discharge of interface 73 are beneficial, therefore are contemplated that in actual fabrication.Imitated in leech
The hole pipeline that the head end end indwelling size of raw cushion 4 is appropriate communicates with suction tube 71, outer suction tube 72 and attraction interface 73.
But the hole pipeline of institute's indwelling can not be too big, the sealing to laryngeal mask is avoided to produce harmful effect.
As shown in FIG. 6 and 7, the class Ring like suction disc face 5 is also arranged on the bionical bottom of cushion 4 of leech including some depressions
The sucker mouth 6 on top layer, each sucker mouth 6 form class annular around the cushion venting cavity 41 of the bionical class annular hollow of cushion 4 of leech and inhaled
Card 5.Each sucker mouth 6 is by the interior suction tube 71 that is arranged in the bionical cushion 4 of leech and is arranged on the bionical cushion 4 of leech
Outer suction tube 72 connects.
Interior suction tube of some sucker mouths 6 that the class Ring like suction disc face 5 is set with being arranged in the bionical cushion 4 of leech
71 connections, interior suction tube 71 go out the bionical tail end of cushion 4 of leech and connect outer suction tube 72, and the outer tail end of suction tube 72 is provided for and born
Press the attraction interface 73 of suction tube connection.During actual use, when the bionical breather laryngeal mask of the leech is inserted in patient's oropharynx cavum laryngis
After completion positions and fixes, interface 73 is attracted to connect vacuum suction.Some sucker mouths 6 are attracted to surround door under suction function
Bottleneck throat mucomembranous surface, and then the class Ring like suction disc face 5 is tightly adsorbed the bottleneck throat mucomembranous surface in surround door, be logical
Laryngeal mask cover body 3 during gas provides enough sealings.
As shown in fig. 6, the sucker mouth 6 includes class Ring like suction disc mouth 61, all kinds of Ring like suction disc mouths 61 and the water of class annular

In this set, the structure of the similar Fig. 6 of the interrupted formation of multiple strip sucker mouths 63 class Ring like suction disc mouth 61.
Simply in the specific implementation, influence from each other reduces the strip sucker mouth 63 of intermittent intervals, and sealing is more during use
Reliably.Multiple strip sucker mouths 63 form the structure of the similar Fig. 6 of two circles class Ring like suction disc mouth 61 in this figure.It is of course possible to set
More multiple class Ring like suction disc mouth structure is put, air-tightness is stronger.
Each depth of sucker mouth 6 is preferably smaller than 1cm, and the purpose of the depth of control sucker mouth 6 is to avoid facial area mucous membrane quilt
Attract drawing stress excessive, cause mucous hyperemia red and swollen.The depth of sucker mouth 6 is smaller, and mucous membrane stress deformation is smaller, and infringement is smaller.
But the depth of sucker mouth 6 is too small, sealing may decline.During actual implementation, the material of the bionical cushion 4 of leech should be sufficiently flexible, and one
Aspect is reduced when can reach use to mucosal injury, on the other hand can increase air-tightness during ventilation.
