As shown in Fig. 3, Fig. 5 and Fig. 6, the sealing of the bionical offer of cushion 3 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 gap occurs in the facial skin at the inner edge edge of class Ring like suction disc face 5 and collar extension nose periphery, because mechanical ventilation is malleation
Ventilation and the inside of class Ring like suction disc face 5 be negative pressure, the liquidity preference of gas is interior to class Ring like suction disc face 5 from the cover body 2 of mask
Flow side.Now under the effect of the pressure differential of ventilation malleation and the negative pressure of class Ring like suction disc face 5, class Ring like suction disc face 5 is arranged on
The seam that facial skin of the deformation of inner ring diaphragm seal circle 51 closure at inner ring edge in class Ring like suction disc face 5 and collar extension nose periphery occurs
Gap opening, the gas leakage in the cover body 2 of mask to class Ring like suction disc face 5 is set not occur still to be just released from.Certain inner ring diaphragm seal
The premises that work of circle 51 are that mask is buckled and covers on patient's mouth and nose periphery, and mask is fixed safe, and this is to lift easily.
The effect that the inner ring diaphragm seal circle 51 improves mask ventilation 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 3 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 occurs in the facial skin of the outer rim edge of class Ring like suction disc face 5 and collar extension nose periphery, because of the pressure of oropharynx cavum laryngis
Power is equal to atmospheric pressure, and the inside of class Ring like suction disc face 5 is negative pressure, and the liquidity preference of gas is to be inhaled out of oropharynx cavum laryngis to class annular
Flow the side of card 5.Now under the effect of the pressure differential of atmospheric pressure and the negative pressure of class Ring like suction disc face 5, class Ring like suction disc is arranged on
Facial skin of the deformation of outer ring diaphragm seal circle 52 closure of the external margin of face 5 in class Ring like suction disc face 5 and collar extension nose periphery occurs
Gap opening at, make the gas leakage in oropharynx cavum laryngis to class Ring like suction disc face 5 not occur still not just being released from.
The sealing of substantially ventilation of gas leakage of the gas of oropharynx cavum laryngis to class Ring like suction disc face 5 to mask has no dry
Disturb, but gas leakage reveals the negative pressure in class Ring like suction disc face 5, makes the facial skin in class Ring like suction disc face 5 and collar extension nose periphery
Surface sticks degree decline, and then declines class Ring like suction disc face 5 and the sealing of mask cover body 2, gas leakage is caused mask
Ventilation failure Probability increase.
As shown in Figures 5 and 6, the class Ring like suction disc face 5 is also arranged on the bionical bottom of cushion 3 of leech including some depressions
The sucker mouth 6 on top layer, each sucker mouth 6 form class annular around the cushion venting cavity 31 of the bionical class annular hollow of cushion 3 of leech and inhaled
Card 5.Each sucker mouth 6 is by the interior suction tube 71 that is arranged in the bionical cushion 3 of leech and is arranged on the bionical cushion 3 of leech
Interface 73 is attracted to connect.
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 3 of leech
71 connections, interior suction tube 71 go out the attraction interface 73 that the bionical tail end of cushion 3 of leech is connected to connect with negative-pressure suction pipe.It is actual
In use, after the bionical Ventilation mask position of the leech is suitable and fixes, interface 73 is attracted to connect vacuum suction.Make in negative pressure
Some sucker mouths 6 are attracted to the facial skin surface of collar extension nose periphery under, and then the class Ring like suction disc face 5 is tightly inhaled
Be attached to collar extension nose periphery facial skin surface, for ventilation when mask cover body 2 enough sealings are provided.
As shown in figure 5, 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
The class annular major axis parallel arranged of the bionical cushion 3 of leech, is mutually isolated.
Two circle class Ring like suction disc mouths 61 are provided with this diagram, class Ring like suction disc mouth 61 is often enclosed and surrounds the bionical cushion of leech
3 annular soft pad venting cavity 31, that is, it is arranged on the position of class Ring like suction disc face 5.Each parallel arranged of class Ring like suction disc mouth 61, mutually
Between it is completely isolated.When in use, it is only to the annular soft pad venting cavity 31 of the bionical cushion of leech 3 often to enclose class Ring like suction disc mouth 61
Sealing effectiveness is erected, mask cover body 2 when the class Ring like suction disc face 5 of the formation of class ring sucker mouth 61 of multi-turn adds actual use
Air-tightness during ventilation.The width of the class Ring like suction disc mouth 61 set during specific implementation is preferred in 5mm or so, number it is more more more
It is good.But limited by the width of class Ring like suction disc face 5, the bionical Ventilation mask class Ring like suction disc face 5 of leech of especially ting model is wide
Degree is smaller, and class Ring like suction disc 61 numbers of mouth are not consistent.
As shown in fig. 6, the sucker mouth 6 includes strip sucker mouth 63, leech of each strip sucker mouth 63 in class annular
Bionical 3 annular top layer of cushion is staggered parallel, is mutually isolated.Each major axis connecting line of strip sucker mouth 63 is around class annular
The class annular hollow portion of the bionical cushion 3 of leech.
In this set, the structure of the similar Fig. 5 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. 5 of two circles class Ring like suction disc mouth 61 in this figure.It is of course possible to set
The structure of more multiple class Ring like suction disc mouth 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 skin quilt
Attract drawing stress excessive, cause facial skin congested red and swollen.The depth of sucker mouth 6 is smaller, and facial skin stress deformation is smaller, damage
Evil is smaller.But the depth of sucker mouth 6 is too small, sealing may decline.During actual implementation, the material of the bionical cushion 3 of leech should be enough
Softness, reduced when on the one hand can reach use and facial skin is damaged, on the other hand can increase air-tightness during ventilation.
As shown in fig. 7, in order to further improve sealing when mask cover body 2 is ventilated, the bionical interior edge of cushion 3 of leech
Major axis sets the air bag 8 of class annular.The gas of appropriate pressure is filled with to the air bag 8 of class annular, utilizes the degree of deformation of of air bag 8 itself
Make cover body 2 higher with patient face portion laminating degree when in use.Meanwhile to reduce the bionical cushion 3 of leech right for the setting of air bag 8
The higher materials demand amount of pliability, reduce manufacturing cost.For the ease of use, can communicated air bags 8 be provided for filling air bag 8
The inflation inlet or gas tube of gas, for it is specifically used when adjust air bag 8 in gas pressure.But on the whole, the pressure of air bag 8
Easily it is low be not easy height, the compliance of air bag 8 is higher when pressure is relatively low, can be closer be fitted in collar extension nose periphery facial skin
