Wherein, breathe the apokoinou construction that interface 1, laryngeal mask snorkel 2 and laryngeal mask cover body 3 is current all laryngeal masks, all laryngeal mask cover body 3 bottoms all arrange the class annular sealing member for sealing.The seal of some laryngeal mask cover body 3 bottoms is set to the annular air-pocket being with gas tube, and other are set to annular gasket.Bottom the oropharynx cavum laryngis of during use, the seal of laryngeal mask and laryngeal mask cover body 3 being inserted patient, after location-appropriate, the housing outer surface of the cover body 3 of similar upside down funnel shape holds on the throat wall mucosa of glottis offside, makes the bell mouth shape peristome of funnel-form cover body 3 put at patient's glottis peripheral around cover.Now, on the throat wall mucosa that seal cover cap encloses outdoors at patient's surround.Like this, the hollow space of cover body 3 funnel structure shrouds the whole glottis of patient, and the housing of cover body 3 struts the bottleneck throat soft tissue of glottis offside, and the seal of annular sticks contact ring provides sealing around the cover body 3 that the bottleneck throat soft tissue of glottis is laryngeal mask.The use success or failure of laryngeal mask are decided by that can the seal of annular provide enough sealings for laryngeal mask.
In the present invention, described annular sealing member is the bionical cushion 4 of Hirudo of class annular, in like manner, during use, bionical for the Hirudo of bionical for described Hirudo breather laryngeal mask head end cushion 4 and cover body 3 are inserted bottom the oropharynx cavum laryngis of patient, after location-appropriate, the housing outer surface of the cover body 3 of similar upside down funnel shape holds on the throat wall mucosa of glottis offside, makes the bell mouth shape peristome of funnel-form cover body 3 put at patient's glottis peripheral around cover.Now, on the throat wall mucosa that Hirudo bionical cushion 4 cover cap encloses outdoors at patient's surround.Now, the hollow space of cover body 3 funnel structure shrouds the whole glottis of patient, and the housing of cover body 3 struts the bottleneck throat soft tissue of glottis offside, and the bionical cushion of Hirudo 4 sticks contact ring and provides basic sealing around the cover body 3 that the bottleneck throat soft tissue of glottis is laryngeal mask.
For increasing the sealing that the bionical cushion 4 of Hirudo provides for laryngeal mask further, described Hirudo bionical cushion 4 bottom arranges profile and substantially fits in use for sealing with the throat wall mucosa that human body surround encloses outdoors the class Ring like suction disc face 5 contacted with the throat wall surface structure that surround encloses outdoors.The class Ring like suction disc face 5 that the throat wall surface structure that profile and surround enclose outdoors is fitted substantially can for providing the sealing on basis when the bionical cushion 4 of Hirudo is fitted with bottleneck throat mucosa.
As shown in Figure 3, described class Ring like suction disc face 5 is communicated with the outer suction catheter 72 be arranged on the bionical cushion of Hirudo 4, and described outer suction catheter 72 tail end is communicated with the attraction interface 73 arranging and be used for being connected with medical negative pressure suction pipe.During use, described attraction interface 73 is communicated with medical negative pressure suction.Under suction function, the class Ring like suction disc face 5 of Hirudo bionical cushion 4 bottom is attracted to the throat wall mucomembranous surface that surround encloses outdoors, the bionical cushion 4 of soft Hirudo is out of shape and the throat wall mucosa that surround sound encloses outdoors can be close to, thus the free surrounding space of cover body 3 inner space and mouth and throat is isolated.In order to reach this effect, the material hardness that the bionical cushion 4 of described Hirudo and class Ring like suction disc face 5 use preferably is less than the hardness of human body mucosa, comprises silica gel, gel etc.
During concrete enforcement, described class Ring like suction disc face 5 is preferably arranged on the midline position of the bionical cushion of Hirudo 4 times category annular major axis, the width in class Ring like suction disc face 5 is less than the width of Hirudo bionical cushion 4 class annular lower surface, and the top layer of the equal indwelling proper width in Hirudo bionical cushion 4 class annular lower surface outside in class Ring like suction disc face 5 is not set to class Ring like suction disc face 5.Like this, during actual use, class Ring like suction disc face 5 is attracted to the throat wall mucomembranous surface that surround encloses outdoors, cushion venting cavity 41 is positioned at glottis front position, the cushion top layer of Hirudo bionical cushion 4 lower surface outside indwelling in class Ring like suction disc face 5 can be pulled the throat wall mucomembranous surface sticking on class Ring like suction disc face 5 outer edge that surround encloses outdoors, plays good sealing function.
During concrete enforcement, class Ring like suction disc face 5 is higher with human body bottleneck throat surface texture laminating degree, and the pressure of negative pressure is larger, and class Ring like suction disc face 5 is more soft, and the bionical cushion of Hirudo 4 just can provide more superior sealing for laryngeal mask cover body 3.During concrete enforcement, the hardness of described Hirudo bionical cushion 4 class Ring like suction disc face 5 material is preferably less than the hardness of human body mucosa, comprises silica gel, gel etc.Like this, under negative-pressure adsorption, class Ring like suction disc face 5 distortion of the bionical cushion 4 of Hirudo is adsorbed on throat wall, instead of throat wall mucosa distortion lift abuts in surface, class Ring like suction disc face 5, avoids negative pressure to cause damage to throat wall mucosa.
During actual fabrication, for the ease of being bonded with cover body 3 by bionical for described Hirudo cushion 4, described Hirudo bionical cushion 4 top can be set to smooth cover body adhesive surface, and corresponding cover body 3 bottom also should be set to smooth adhesive surface.Certainly, bonding is the optimal way that is tightly connected with cover body 3 of the bionical cushion 4 of Hirudo just, can also adopt buckle, inlay, the mode such as ultrasonic curing, is tightly connected with cover body 3 as long as can reach the bionical cushion 4 of Hirudo.
As shown in Figure 4 and Figure 5, described class Ring like suction disc face 5 comprises the cellular annular circle body 50 of setting the solid netted class sponge structure being arranged on class annular Hirudo bionical cushion 4 lower surface.
Described cellular annular circle body 50 is communicated with the outer suction catheter 72 be arranged on the bionical cushion of Hirudo 4, can be communicated with by the attraction interface 73 being arranged on outer suction catheter 72 tail end with the Medical negative pressure seal of tube.Certainly, the outer edge of cellular annular circle body 50 should arrange sealing ring, after attraction interface 73 is communicated with the Medical negative pressure seal of tube, sealing ring can be avoided leaking gas and occur, cellular annular circle body 50 cellular space distortion under suction function is reduced, the throat wall mucomembranous surface making the sunken contraction of cellular annular circle body 50 be close to surround to enclose outdoors, plays preferably sealing function.
Described cellular annular circle body 50 is preferably arranged on the midline position of the bionical cushion of Hirudo 4 times category annular major axis, the width of cellular annular circle body 50 is less than the width of Hirudo bionical cushion 4 class annular lower surface, and Hirudo bionical cushion 4 class annular lower surface outside all indwelling proper width in cellular annular circle body 50.Like this, during actual use, cellular annular circle body 50 is attracted to the throat wall mucomembranous surface that surround encloses outdoors, cushion venting cavity 41 is positioned at glottis front position, the cushion top layer of Hirudo bionical cushion 4 lower surface outside indwelling in cellular annular circle body 50 can be pulled the throat wall mucomembranous surface sticking on cellular annular circle body 50 outer edge that surround encloses outdoors, plays good sealing function.
During concrete enforcement, the more soft material of described cellular annular circle body 50, cellular space is finer and closely woven, and the sealing property provided during use is better.The prompting of value: during actual fabrication, at Hirudo bionical cushion 4 bottom annularly major axis indwelling class in advance ring-shaped depression groove, then can be mounted with the cellular annular circle body 50 that profile size is mated in class ring-shaped depression groove.Arrange interior suction catheter 71 in the edge, interior annular groove outer ring of described Hirudo bionical cushion 4 bottom to seal with outer suction catheter 72 and be communicated with, for negative pressure provides conducting path.
As shown in Fig. 4, Fig. 6 and Fig. 7, be the sealing that Hirudo bionical cushion 4 when improving use further provides, described class Ring like suction disc face 5 inner ring edge part arranges the inner ring diaphragm seal circle 51 of soft quality class annular.
The meaning arranging the inner ring diaphragm seal circle 51 of soft quality class annular at class Ring like suction disc face 5 inner ring edge part is: during use, if when there is gap in edge, inner edge, class Ring like suction disc face 5 and pharyngolaryngeal mucosa, because mechanical ventilation is positive airway pressure, inside, class Ring like suction disc face 5 is negative pressure, and the liquidity preference of gas is flow to side, class Ring like suction disc face 5 in the cover body 3 of laryngeal mask.Now under the pressure differential effect of ventilate malleation and class Ring like suction disc face 5 negative pressure, the inner ring diaphragm seal circle 51 being arranged on class Ring like suction disc face 5 internal edge is out of shape the gap opening place that shutoff occurs with pharyngolaryngeal mucosa in class Ring like suction disc face 5, make in the cover body 3 of laryngeal mask to the gas leakage in class Ring like suction disc face 5 still generation just removed.The prerequisite that certain inner ring diaphragm seal circle 51 works is the location-appropriate of laryngeal mask patient pharyngolaryngeal cavity, and laryngeal mask is fixed safe, and this is lift easily in current laryngeal mask technology.
The effect that described inner ring diaphragm seal circle 51 improves laryngeal mask airway sealing depends on: the thickness of inner ring diaphragm seal circle 51, the material softness degree of inner ring diaphragm seal circle 51, the width of inner ring diaphragm seal circle 51.Inner ring diaphragm seal circle 51 thickness is thinner, more soft material, and width is wider can provide more superior sealing effectiveness.But inner ring diaphragm seal circle 51 thickness is thinner, more soft material, and width is wider, during actual use, inner ring diaphragm seal circle 51 is more curling, causes sealing property to decline.The parameters of inner ring diaphragm seal circle 51 can be regulated during concrete manufacture according to actual experiment effect, make inner ring diaphragm seal circle 51 sealing effectiveness reach best.
In like manner, be the sealing that Hirudo bionical cushion 4 when improving use further provides, outer ring, described class Ring like suction disc face 5 edge part arranges the outer ring diaphragm seal circle 52 of soft quality class annular.
The meaning that outer ring, described class Ring like suction disc face 5 edge part arranges the outer ring diaphragm seal circle 52 of soft quality class annular is: during use, if when there is gap in outer rim edge, class Ring like suction disc face 5 and pharyngolaryngeal mucosa, because the pressure of oropharynx cavum laryngis equals atmospheric pressure, and inside, class Ring like suction disc face 5 is negative pressure, the liquidity preference of gas is flow to side, class Ring like suction disc face 5 in oropharynx cavum laryngis.Now under the pressure differential effect of atmospheric pressure and class Ring like suction disc face 5 negative pressure, the outer ring diaphragm seal circle 52 being arranged on class Ring like suction disc face 5 external margin is out of shape the gap opening place that shutoff occurs with pharyngolaryngeal mucosa in class Ring like suction disc face 5, make in oropharynx cavum laryngis to the gas leakage in class Ring like suction disc face 5 still generation just removed.In like manner, the Digestive system that intraoral secretions and digestive tract backflow also just gets clogged before inflow class Ring like suction disc face 5.
The gas of oropharynx cavum laryngis is noiseless to the sealing of the ventilation of laryngeal mask to the gas leakage in class Ring like suction disc face 5 in essence, but gas leakage makes the negative pressure in class Ring like suction disc face 5 reveal, the degree that sticks of the throat wall mucomembranous surface that class Ring like suction disc face 5 and surround are enclosed outdoors declines, and then class Ring like suction disc face 5 is declined with the sealing of laryngeal mask cover body 3, make gas leakage cause laryngeal mask airway failure Probability to increase.
But mouth intracavity liquid enters class Ring like suction disc face 5 through class Ring like suction disc face 5 and the gap opening of pharyngolaryngeal mucosa, and be useful through interior suction catheter 71, outer suction catheter 72 and the discharge of attraction interface 73, therefore can consider when actual fabrication.At the suitable hole pipeline of the head end end indwelling size of the bionical cushion of Hirudo 4 with suction catheter 71, outer suction catheter 72 with attract interface 73 to communicate.But the hole pipeline of institute's indwelling can not be too large, avoid producing harmful effect to the sealing of laryngeal mask.
As shown in FIG. 6 and 7, described class Ring like suction disc face 5 also comprises the sucker mouth 6 that some depressions are arranged on top layer, Hirudo bionical cushion 4 bottom, and each sucker mouth 6 forms class Ring like suction disc face 5 around the cushion venting cavity 41 of Hirudo bionical cushion 4 class annular hollow.Each sucker mouth 6 is communicated with the outer suction catheter 72 be arranged on the bionical cushion of Hirudo 4 by being arranged on suction catheter 71 in the bionical cushion of Hirudo 4.
Some sucker mouths 6 that described class Ring like suction disc face 5 is arranged all are communicated with the interior suction catheter 71 be arranged in the bionical cushion of Hirudo 4, interior suction catheter 71 goes out Hirudo bionical cushion 4 tail end and connects outer suction catheter 72, and outer suction catheter 72 tail end arranges the attraction interface 73 being used for being connected with negative-pressure suction pipe.Actual when using, insert in patient's oropharynx cavum laryngis to complete when the bionical breather laryngeal mask of described Hirudo and locate and after fixing, attraction interface 73 connects vacuum suction.Under suction function, some sucker mouths 6 are attracted to the bottleneck throat mucomembranous surface of surround door, and then make described class Ring like suction disc face 5 tightly be adsorbed on the bottleneck throat mucomembranous surface of surround door, for the laryngeal mask cover body 3 during ventilation provides enough sealings.
As shown in Figure 6, described sucker mouth 6 comprises class Ring like suction disc mouth 61, and all kinds of Ring like suction disc mouth 61 and the class annular major axis parallel arranged of the bionical cushion 4 of Hirudo of class annular, isolate mutually.

As shown in Figure 7, described sucker mouth 6 comprises rectangular sucker mouth 63, and each strip sucker mouth 63 is parallel on the annular top layer of the bionical cushion of the Hirudo of class annular 4 to be staggered, and isolates mutually.Each strip sucker mouth 63 major axis connecting line is around the class annular hollow portion of the bionical cushion 4 of Hirudo of class annular.
In this set, the structure of the class Ring like suction disc mouth 61 of similar Fig. 6 of formation that multiple strip sucker mouth 63 is interrupted.Just the strip sucker mouth 63 of intermittent intervals in the specific implementation, and the impact mutually reduces, and during use, sealing is more reliable.In this figure, multiple strip sucker mouth 63 forms the structure of the class Ring like suction disc mouth 61 of the similar Fig. 6 of two circles.Certainly can arrange more multiple class Ring like suction disc mouth structure, air-tightness is stronger.
Described each sucker mouth 6 degree of depth is preferably less than 1cm, and the object controlling sucker mouth 6 degree of depth is that to avoid facial area mucosa to be attracted tractive stressed excessive, causes mucous hyperemia red and swollen.Sucker mouth 6 degree of depth is less, and mucosa stress deformation is less, damages less.But sucker mouth 6 degree of depth is too small, sealing may decline.During actual enforcement, the material of the bionical cushion 4 of Hirudo should be enough soft, reduces mucosal injury, can increase air-tightness when ventilating on the other hand when can reach use on the one hand.
As shown in Figure 8, in order to improve sealing when laryngeal mask cover body 3 is ventilated further, the air bag 8 of class annular is set along major axis in the bionical cushion 4 of described Hirudo, air bag 8 to class annular is filled with the gas of suitable pressure, utilizes the degree of deformation of air bag 8 itself to make cover body 3 degree of fitting with patient face portion in use higher.Meanwhile, the setting of air bag 8 decreases the higher materials demand amount of the bionical cushion of Hirudo 4 pairs of pliabilitys, reduces manufacturing cost.For the ease of using, the inflation inlet or gas tube that are used for air bag 8 inflation can being set communicated air bags 8, during for specifically using, regulating the pressure of gas in air bag 8.But on the whole, the pressure of air bag 8 is easily low not easily high, and when pressure is lower, the compliance of air bag 8 is higher, can be closer be fitted on bottleneck throat mucosa that surround encloses outdoors.
As shown in Figure 2, run through the bionical breather laryngeal mask major axis of described Hirudo and arrange gastral cavity relief pipe 9, described gastral cavity relief pipe 9 opening is positioned at Hirudo bionical cushion 4 head end end, and main body is embedded in cover body 3 and breather 2, and outlet is arranged on breather 2 tail end.
