With reference to specific accompanying drawing, the invention will be further described.
As shown in Figures 1 and 2, the bionical breather laryngeal mask of a kind of leech, including the breathing for being connected with breathing pipeline Interface 1 and breathing sealing joint connection laryngeal mask snorkel 2, with laryngeal mask snorkel 2 sealing connect be used for holding in bottleneck throat Glottis is horizontal and cover covers the laryngeal mask cover body 3 enclosed outdoors in surround and top and the sealed connection of cover body cover mouth is used for when in use and ring The bionical cushion 4 of leech of the peripheral throat wall mucous membrane of glottis class annular in sealing contact.
Wherein, the apokoinou construction that interface 1, laryngeal mask snorkel 2 and laryngeal mask cover body 3 are current all laryngeal masks, all larynxs are breathed The bottom of cover cover body 3 is respectively provided with the class annular sealing member for sealing.The seal of some bottoms of laryngeal mask cover body 3 is arranged to Annular air-pocket with gas tube, other are arranged to annular gasket.The seal of laryngeal mask and laryngeal mask cover body 3 are inserted into trouble during use The oropharynx cavum laryngis bottom of person, the housing outer surface of the cover body 3 of similar upside down funnel shape is held in glottis offside after location-appropriate On throat wall mucous membrane, the bell mouth shape opening portion of funnel-form cover body 3 is set to be put around cover in patient's glottis periphery.Now, seal Cover is covered on the throat wall mucous membrane enclosed outdoors in patient's surround.So, the hollow space of the funnel structure of cover body 3 shrouds patient's whole sound Door, the housing of cover body 3 strut the bottleneck throat soft tissue of glottis offside, and annular seal sticks bottleneck throat of the contact around glottis Soft tissue provides sealing for the cover body 3 of laryngeal mask.Laryngeal mask is decided by that can the seal of annular provide for laryngeal mask using success or failure Enough sealings.
In the present invention, the annular sealing member is the bionical cushion 4 of leech of class annular, similarly, by the leech during use The bionical cushion 4 of leech and cover body 3 of bionical breather laryngeal mask head end insert the oropharynx cavum laryngis bottom of patient, after location-appropriate it is similar fall The housing outer surface for putting funnelform cover body 3 is held on the throat wall mucous membrane of glottis offside, makes the horn mouth of funnel-form cover body 3 Put around cover in patient's glottis periphery shape opening portion.Now, the bionical cushion 4 of leech covers the throat wall for building and being enclosed outdoors in patient's surround On mucous membrane.Now, the hollow space of the funnel structure of cover body 3 shrouds patient's whole glottis, and the housing of cover body 3 struts glottis offside Bottleneck throat soft tissue, the bionical cushion 4 of leech stick contact and provided substantially for the cover body 3 of laryngeal mask around the bottleneck throat soft tissue of glottis Sealing.
It is the sealing that laryngeal mask provides for the further increase bionical cushion 4 of leech, the bionical bottom of cushion 4 of leech is set Profile is bonded the throat wall for being used to enclose outdoors with human body surround when in use substantially with the throat wall surface structure that surround encloses outdoors Mucous membrane class Ring like suction disc face 5 in sealing contact.The class annular that profile is bonded substantially with the throat wall surface structure that surround encloses outdoors Sucker face 5 provides the sealing on basis when can be bonded for the bionical cushion 4 of leech with bottleneck throat mucous membrane.
As shown in figure 3, the class Ring like suction disc face 5 connects with the outer suction tube 72 being arranged on the bionical cushion 4 of leech, institute 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 Portion may be configured as smooth cover body adhesive surface, and the corresponding bottom of cover body 3 should also be arranged to smooth adhesive surface.Certainly, bonding The preferred embodiment that to be the bionical cushion 4 of leech be tightly connected with cover body 3, buckle can also be used, inlayed, the mode such as ultrasonic curing, As long as the bionical cushion 4 of leech can be reached to be tightly connected with cover body 3.
As shown in Figure 4 and Figure 5, the class Ring like suction disc face 5 includes setting being arranged on the bionical bottom of cushion 4 of class annular leech The cellular annular circle body 50 of the solid netted class sponge structure on surface.
The cellular annular circle body 50 connects with the outer suction tube 72 being arranged on the bionical cushion 4 of leech, by being arranged on The attraction interface 73 of the outer tail end of suction tube 72 can connect with the Medical negative pressure seal of tube.Certainly, the interior outside of cellular annular circle body 50 Edge should set sealing ring, and sealing ring is avoided that gas leakage after attracting interface 73 to be connected with the Medical negative pressure seal of tube, makes honeycomb The cellular space deformation under suction function of annular body 50 is reduced, and the sunken contraction of cellular annular circle body 50 is close to surround door The throat wall mucomembranous surface of periphery, plays preferable sealing function.
The cellular annular circle body 50 is preferably provided at the midline position of 4 times category annular major axis of the bionical cushion of leech, honeybee The width of nest annular body 50 is less than the width of the bionical class annular lower surface of cushion 4 of leech, and under the bionical class annular of cushion 4 of leech Surface outside indwelling proper width in cellular annular circle body 50.So, cellular annular circle body 50 is adsorbed during actual use In the throat wall mucomembranous surface that surround encloses outdoors, cushion venting cavity 41 is located at glottis front position, and the bionical lower surface of cushion 4 of leech exists The cushion top layer of outside indwelling, which can be pulled, in cellular annular circle body 50 sticks in the cellular annular circle body 50 that surround encloses outdoors Outer peripheral throat wall mucomembranous surface, plays good sealing function.
When it is implemented, the more soft material of the cellular annular circle body 50, cellular space is finer and closely woven, provides during use Sealing property it is better.The prompting of value is:During actual fabrication, it can be stayed in advance along annular major axis in the bionical bottom of 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 The class annular major axis parallel arranged of the bionical cushion 4 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 4 annular soft pad venting cavity 41 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 41 of the bionical cushion of leech 4 often to enclose class Ring like suction disc mouth 61 Sealing effectiveness is erected, laryngeal mask cover body 3 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 breather laryngeal 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. 7, the sucker mouth 6 includes strip sucker mouth 63, leech of each strip sucker mouth 63 in class annular Bionical 4 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 4 of leech.
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.
As shown in figure 8, in order to further improve sealing when laryngeal mask cover body 3 is ventilated, the bionical interior edge of cushion 4 of leech Major axis sets the air bag 8 of class annular, is filled with the gas of appropriate pressure to the air bag 8 of class annular, utilizes the degree of deformation of of air bag 8 itself Make cover body 3 higher with patient face portion laminating degree when in use.Meanwhile to reduce the bionical cushion 4 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 low to be not easy height, the compliance of air bag 8 is higher when pressure is relatively low, and the bottleneck throat that surround encloses outdoors that is fitted in that can be closer glues On film.
As shown in Fig. 2 gastral cavity relief pipe 9, the gastral cavity relief pipe 9 are set through the leech bionical breather laryngeal mask major axis Opening is located at the bionical head end end of cushion 4 of leech, and main body is embedded in cover body 3 and breather pipe 2, and outlet is arranged on the tail of breather pipe 2 End.
The gastral cavity relief pipe 9 is isolated with the bionical breather laryngeal mask venting cavity of the leech, in use, positioned at bionical in leech The opening of gastral cavity relief pipe 9 of the head end of cushion 4 is positioned at esophageal aperture, when stomach cavity pressure is higher, gastral cavity content(Liquid Or gas)It can be discharged via gastral cavity relief pipe 9.If necessary can the outlet of the configured gastral cavity relief pipe 9 in the tail end of breather pipe 2 put Enter to depressurize stomach tube.The gastral cavity relief pipe 9 is isolated with the bionical breather laryngeal mask venting cavity of the leech.
The opening of gastral cavity relief pipe 9 is preferably provided to porous engraved structure, gastral cavity decompression during normal use The opening of pipe 9 is located at the minimum position of human body oropharynx cavum laryngis gap, and intraoral liquid can be entered by porous engraved structure Row is more thoroughly removed, can solve to use at present laryngeal mask can not the puzzlement cleared up of counterpart luminal sectetion, reduction laryngeal mask Secretion sucks the risk of air flue by mistake during extraction.
Operation terminates, and patient awoke and autonomous respiration recover after improving, and are open through the gastral cavity relief pipe 9 to patient oral cavity Interior liquid carries out attraction cleaning, the medical negative pressure suction for attracting interface 73 to connect is withdrawn, the negative pressure in class Ring like suction disc face 5 disappears Lose, class Ring like suction disc face 5 disappears to the absorption affinity of throat wall mucous membrane, you can easily extract the bionical breather laryngeal mask of the leech, tie Beam operates.
