Description
This case is the Application No. 201510884151.2 using the applying date as 2015-12-04, and entitled " one kind is without laryngoscope
Tracheal inserting device " the divisional application that is carried out for female case of patent of invention.
Technical field
The present invention relates to medical devices technical field, independently exhaled on specifically a kind of trachea cannula, glottis
Inhale and can positive airway pressure device, and alternative laryngeal mask function and the ventilation managing device of tracheal catheter.
Background technology
1st, trachea cannula and difficult airway processing：
Up to the present, when patient needs trachea cannula, medical worker is frequently necessary in patient's deep sedation and whole body
In the state of anesthesia, and muscle relaxant is needed to use to complete intubation task.If selection is intubated when patient regains consciousness,
Bronchoscope and its high technology of operator, patient's downern and psychological preparation and cooperation are needed, and is taken.
Either using clinical widely used curved formula laryngoscope blade or straight laryngoscope blade at present, all easily patient airway is caused to damage.When
Patient's difficulty in opening mouth, obesity, tracheae and glottis deformation are run into, or provokes epiglottis portion with laryngoscope and is still difficult to appear glottis, or
In the patient of respiratory tract wound, its bottleneck throat is filled with blood and secretion, direct-view epiglottis and glottis is become highly difficult or basic
It is impossible.Despite the doctor by years of training, still result in trachea cannula and be strayed into esophagus or can not be intubated.
There are many devices to help routine or difficult tracheal intubation at present.Wide variety of is a kind of laryngoscope for carrying screen
Device, these devices depend on and see epiglottis and glottis indirectly.It is but complete using these devices for above-mentioned difficulties case
It is still extremely difficult even possible into intubation task.
The another kind of device generally used is according to United States Patent (USP)：5,303,697；6,079,409 and Chinese patent：
CN1859939A, doctor of medicine's cloth reyn (DR.BRAIN) describe " intubating laryngeal mask airway device with fiber optic assembly ",
Trade mark registration name：fastrack.This device in Clinical practice for many years.Early production in them is the side of " blindmate "
Formula, without seeing epiglottis and glottis.Recent product adds fibre optic viewing device, can provide a user external video
Observation.But this product has significant portion to be made up of metal material, and near-end directly forms 90 ° of a camber with distal end, such as
Fruit disease people difficulty in opening mouth or without using enough muscle relaxants, it may be difficult to throat is inserted by patient's mouth, and easily
Damage the soft tissue of bottleneck throat.Even if being placed into the throat of patient, as described in fastrack operation instructions, still having can
It can cause to push down epiglottis, close glottis, or even can obstructing airway ventilation.Fastrack is U.S. Patent number 5,303,697；6,
079,409 direct products.
Although DR.BRAIN is described in United States Patent (USP) 7,218,071B2 and corresponding Chinese patent CN1859939B
Add fibre optic viewing device on the basis of " intubating laryngeal mask airway device ", but it is above-mentioned the problem of still have.Separately
Outside, its epiglottis elevator bar needs just push away in a very close position and appropriate angle, epiglottis elevator bar with epiglottis
Dynamic epiglottis is upward, appears glottis, and then tracheal catheter inserts.This is obviously unapproachable in many cases, and it is also
A special tracheal catheter is needed, it is more expensive compared with commonly used tracheal catheter.
Other video Intubaction devices, such as glidescope, Karl ' storz (karr An Tuosi) electronics trachea cannula
Mirror, or Airtraq.It is required for the angle for first provoking epiglottis and its bending using metal or hard plastics laryngoscope all close
90 degree or more than 90 degree, therefore easily damage bottleneck throat tissue.
It is intubated by branchofiberoscope (abbreviation Bronchofiberscope) for difficult airway, has been considered as standard for a long time, its
Also the difficult airway processing of children is included, but it also has wretched insufficiency.A representative scientific articles are sent out for 2013
Table is shown in journal of Anesthetology Clinical Pamacology (clinical anesthesia pharmacology magazine), with fibre
Branch mirror intubation first time success rate is only 20%.It is 73.3% such as by laryngeal mask Bronchofiberscope first time success rate, then tries the again
Secondary, third time even more times, adds up success rate 90%, and is grown in alone light mirror intubation group, intubation time, 40%
Children reduce blood oxygen saturation (oxygen desaturation).
An another piece is published in famous magazine " management of breathing " (Respiratory care) for 2014, is one by U.S.
One University Medical College anesthesia portion of state integrates the summary article of the fibre scope intubation in North America.Author explicitly point out " it is important that
It should be noted that fibre scope is intubated the case in neck injury, its success rate and clinical effectiveness are not better than other intubation techniques ".
And the investigation that they are made shows that " during 500 U.S. anesthesia academicians write in reply, 78% member uses fibre scope " is " many
Member recognizes that they with the technology of fibre scope are also limited ".It should be noted that these member doctors, have excessive tight
Lattice are trained and abundant clinical experience.
As it was previously stated, other intubation technique devices also have numerous deficiencies.Therefore the present invention seeks to make up these deficiencies,
Routine tracheal intubation and difficult tracheal intubation are easier, is had higher success rate, it is smaller or lossless to patient's bottleneck throat tissue damage
Wound.
2, the use of laryngeal mask：
Laryngeal mask since by the doctor of medicine, more years of British physician DR.BRAIN30 through invention since (United States Patent (USP) 4,509,514
On April 9th, 1985), by global anesthesia EMT's extensive utilization, it is considered to be anaesthetized boundary in past more than 20 years
Most great invention.But it still has the shortcomings that its own fixation.He cannot be used for the full patient of stomach first.Although at present
There is the laryngeal mask added with gastric juice drainage, but gastric content suction tracheae still happens occasionally.Secondly its top is being put into patient's mouth
During may be folded, or the inflatable cover such as improper use of its near-end, can top pressure epiglottis, cause glottis to block.Also
Due to its sealing property deficiency, it is impossible to be used in positive airway pressure.Although it can also see that some cases are reported once in a while, for selectivity
The positive airway pressure of patient, but can only also use less than conventional positive airway pressure, and can only the short time use.
Other numerous similar laryngeal mask or glottis epithelium healing devices, Chinese patent CN102427842B；CN101842129B；
CN103432670B；CN1956746B；102727978B；CN101208125B；CN103037927B and United States Patent (USP) 8,
778,248, all different degrees of has disadvantages mentioned above.
The invention is intended to overcome these shortcomings.Create a kind of new glottis epithelium healing device.
3rd, positive airway pressure：
For a long time, either perform an operation, or CICU, when sick human or animal needs positive airway pressure, all need
Tracheal catheter is inserted, then various anaesthetic gases are pushed into lung and led to by lung ventilator or artificial positive pressure ventilation
Gas, and tracheal catheter is made up of harder plastics, once touching tracheae, sensitive liner mucous membrane will result in damage.

This arrangement to accompany of the position relationship of glottis, breather line 1 and Bronchofiberscope pipe is one of features of the present invention.
Breather line 1 is close to Bronchofiberscope pipe and manufactures one, but two tube chambers and is not communicated with, and Bronchofiberscope pipe is one similar
Square tube chamber, its internal diameter and cross section are less than breather line.It, to distal end, is close to since the near-end beginning of pipe-line system
The upper right outer wall of breather line 1, little by little slightly walks downwards, is located at when reaching the distal end of breather line 1 in the outer wall of the right
Portion.
Gas-bag system：
It is close to gas-bag system outside the tube wall of the distal end of pipe-line system, gas-bag system includes a horizontal air bag 4 and indulged
To air bag 6, the airbag chamber of the two is not communicated with, and is not also communicated with the tube chamber of pipe-line system.By respective inflation tubule (i.e.
First gas tube 50 and the second gas tube 70) can be respectively to respective airbag aeration and deflation.
(i.e. the first air pressure indicates the He of folliculus 51 to all each own air pressure instruction folliculus of the inflation tubule near-end of two difference
Second air pressure indicates folliculus 71) and connected therewith one inflation check valve, this inflates the gas that check valve can prevent from being filled with
Body spills air bag automatically.Only in firmly outwards pumping, this valve can be just opened, extracts the gas in air bag out.
Longitudinal air bag 6 is close to the outside of pipe-line system distal end lower wall, consistent with pipe-line system trend, therefore claims longitudinal gas
Capsule, the first half of longitudinal air bag 6 is located at below pipe-line system distal end, wedge shaped, and inflation tubule (the second gas tube 70) is direct
It is connected with it, so being inflated first, therefore the first air bag 61 or air bag #1 can be claimed, the latter half of of longitudinal air bag 6 is located at pipeline system
Below the distal end of system, it is connected in outer convex, and by the narrow middle part (i.e. narrow 60) of longitudinal air bag 6, itself is also
Without the inflation tubule being joined directly together, only after the inflation of the first air bag 61 reaches certain intrinsic pressure, air-flow passes through middle part
Narrow, the latter half of of longitudinal air bag 6 could be flowed to, therefore have certain delay, therefore claim the second air bag 62 or air bag #2.It is vertical
To air bag 6 in inflation, the first air bag 61 is inflated first, then the second air bag of gas flow 62, and this temporal order makes
The miscellaneous part function of obtaining main part of the invention is done in an orderly way.
Longitudinal air bag 6 can lift the end of pipe-line system after inflating, allow the first epiglottis to elect piece 3 indirectly and lean on itself
Elastic force stretches and the distal openings in extending aeration pipe road 1, so as to elect epiglottis.
Horizontal air bag 4 is compared with longitudinal air bag 6, and its capacity is larger, but pressure is relatively low.The wall of horizontal air bag 4 is relatively thin, easily
Expansion is inflated, is also easily compressed by dissection protuberance, so it adapts to local normal anatomy and variation, so as to it and week
The mucous membrane for enclosing bottleneck throat creates good sealing while excessive pressure will not be caused to the mucous membrane of bottleneck throat.
For horizontal air bag 4 when positioned at the top of pipe-line system, tube chamber becomes very thin, and elects piece 3 positioned at the first epiglottis
Underface.As the first airbag aeration raises the distal end of pipe-line system, the first epiglottis elects piece and raised therewith, finally by pars oralis pharyngis
Antetheca stops, therefore when the first epiglottis election piece 3 bears the stop pressure of pars oralis pharyngis antetheca, can be pressed down against, partly or completely
Entirely close its tube chamber.Allow in the case the left side of horizontal air bag 4 and right part can not mutual traffic, and formed
Similar to two independent air bags, therefore the tubule (i.e. the first gas tube 50) of a horizontal airbag aeration of the present invention,
When close to horizontal air bag 4, it will be divided into two, the smaller inflation tubule of two to be divided into two piece will be respectively coupled to horizontal gas
The left part and right part of capsule 4, so when the middle part of horizontal air bag 4 is closed by compression, still can be to transverse direction by the first gas tube 50
Left part and the right part inflation of air bag 4.Because the first gas tube 50 is divided into two, the gas being filled with flows into a left side for horizontal air bag 4
Portion or right part, the interior pressure depending on the air bag of which side are smaller.This mechanism makes horizontal air bag 4 seem there is a kind of self-control
Horizontal cell parts at left and right sides of making are suitable for normal bottleneck throat and variation dissection and may thus to a certain extent
It is leftward or rightward to elapse the opening of breather line 1, so as to more accurately correspond to glottis opening, makes intubation and ventilation more easy.
But in alternative example, two air bags can be able to and be an air bag, it is only necessary to an inflation tubule and an air pressure
Indicate folliculus.The mode of appearance of the air bag of this two-in-one as the outward appearance of former two air bags, also can by the function performed by it
Equally, therefore former horizontal air bag can be described as the lateral part of air bag.Accordingly, former longitudinal air bag is referred to as the longitudinal component of air bag.
And uniquely inflating tubule can be connected with the lateral part of air bag or longitudinal component and inwardly inflate.See Fig. 7 b.It is possible thereby to
Simplify manufacturing process.Accordingly, in the application present invention and operation, air bag only needs inflation once.
Basal part：
Basal part is substantially by relatively thin plastic sheet, from closely to remote, it constitutes the bottom of liquid storage cylinder 10, and it first
Both sides be tipping up constituting two side and the top blind flange of liquid storage cylinder, therefore liquid storage cylinder has compressibility, can be with surrounding
Organize the formation of closing.Then it is connected as a single entity with upright crozier 9, is then tightly connected with the bottom of the first air bag again, finally becomes
Narrow thickening into a similar narrow sheet, referred to as substrate attaches body 8, positioned at the lower left of pipe-line system, and and pipe-line system
Outer wall it is molten be integrated, such substrate attach body 8 just become a kind of method that basal part is connected to pipe-line system.
The front end of the evagination arc of basal part is the opening (i.e. inlet 100) of liquid storage cylinder 10.In the preferred embodiment, its
The neighbouring constituent material that is open is softer compared with the material of other parts liquid storage cavity wall, can be varied from pressure and topography.
There is an inside projection at the middle part that substrate attaches body 8, behind the first air bag 61 of longitudinal air bag 6, by
This causes the narrow 60 between the first air bag 61 and the second air bag 62, and this narrow is intended to postpone the inflation of the second air bag 62
Time and limitation air-flow flow to the speed of the second air bag 62 from the first air bag 61.But in alternative example, this inside reality
Projection, it can be removed.So as to which the attached body of substrate would not cause the narrow between the first air bag and the second air bag, so as to letter
Change manufacturing process.
The upright crozier 9 and its crook 90 of basal part, are made up of flexible silica gel, silicon rubber or plastics.
Before apparatus of the present invention are pushed into bottleneck throat, the first epiglottis at the top of pipe-line system can be suppressed and elect piece 3, filled in the present invention
Put and be pushed into after bottleneck throat, and the first air bag 61 is filled with air, upright crozier 9 and its crook 90 " will discharge "
One epiglottis elects piece 3, so as to praise epiglottis.
Esophagus drainage tube：
Another mechanism that basal part is connected with pipe-line system is esophagus drainage tube 11, and esophagus drainage tube 11 is from closely to remote, opening
Begin to walk in the underface of the lower right, i.e. Bronchofiberscope pipe of pipe-line system, be tightly affixed inseparable, but both tube chambers not phase
It is logical.Then separate with pipe-line system in pipe-line system distal end, be then connected with the right side of basal part, the right side with upright crozier 9
Side is tightly adjacent, inseparable, is finally opened on the liquid storage cylinder 10 of basal part distal end, and esophagus drainage tube 11 also may be provided in the left side,
It also should be within concept of the present invention.
The distal openings of esophagus drainage tube 11 can be drained in liquid storage cylinder 10 in liquid storage cylinder 10 by vitro Adsorption device
Thing is in external in liquid storage body and some little particle stomaches, and esophagus drainage tube 11 is close to together in the near-end and middle-end of pipe-line system
OK, another mechanism that pipe-line system is connected with basal part is thus provided.And liquid storage cylinder is made up of relatively thin plastic sheet
Moreover compressibility, and liquid storage cylinder is located at the distal end of esophagus drainage tube, is sealed so liquid storage cylinder can be formed with esophageal tissue around
Close, prevent esophageal content reflux, while when pressing ventilation, this closing can prevent barotropic gas from entering esophagus.
Intubation guiding probe：
Intubation guiding probe 15, although its main part not with the present invention is connected, it is the independence of the present invention
Part, it is about about 2-3 times than whole pipe-line system.Its near-end is in the shape of slight curvature, the sickle shaped of its distal end
Bending is the innovative design of the present invention, hereinafter referred to as probe.
The form of probe distal end and the material of making are the importances of the present invention.Its barred body can be bent, and be a kind of phase
Solid plastic materials are made, hardness 40-55A.Its distal end by a kind of softer and be rich in flexible material and be made, and
And surface unusual light, it can be made up of the material of specific relatively low coefficient of friction, the similar things of PTFE can be also coated on its surface
Matter, change direction so easily being slided when meeting obstructions, and the tissue of surrounding will not be made to have damage, therefore can be successfully
" searching " and into glottis.
The sickleshaped of probe end can be divided into first end section 150 and second end section 151, first end section 150 and rod
The angle of body can be in the angle between 125-155 °, and the angle of second end section 151 and first end section 150 can be in 110-150 °
Between angle.This falculate end, by being made with good elastic and more soft material.In preferable example
In, second end section 151 is in slightly bent arc, and the end of second end section 151 is rounded, and surface can coat coefficient of friction very little
Material, make its surface unusual light.These features can be such that the sickle shaped end of probe is slided from the big direction small to resistance of resistance
It is dynamic.And sickle -shaped bending can help to guide tracheal catheter 16 to avoid tracheal catheter 16 from stopping hanging over the vocal cords of glottis by glottis
Upper even damage vocal cords.
Application Example
First, intubation guiding probe 15 is coated medical aseptic lubricant and is inserted into tracheal catheter 16, and its is falculate remote
The opening through the distal end of tracheal catheter 16 is held, then pulls out the standard 15mm interfaces of the near-end of tracheal catheter 16, then tracheae is led
The outer wall of pipe 16 coats medical aseptic lubricant, is then inserted into the breather line 1 of the present invention, until the second epiglottis elects piece
Before 13 position.Gas is fully drawn out in gas-bag system.First epiglottis elects piece 3 and bent downwards, positioned at the straight of basal part
Under the compacting of the crook 90 of vertical crozier 9.Again by the distal portions of apparatus of the present invention main part, particularly in basal part
Backside on medical aseptic lubricant.
Two fingers of operator, just as routine tracheal intubation.The separated sick human or animal's of " scissors " formula
Upper tooth and lower tooth.The distal end of apparatus of the present invention is put into the mouth of patient or animal by the other hand, then operator with one or
Two fingers, which are pushed down, makes its back curve to oral cavity in the middle part of apparatus of the present invention, and pushes down on apparatus of the present invention simultaneously along tongue
Root back curve radian enters the bottleneck throat of sick human or animal, when the opening of the liquid storage cylinder 10 of basal part end is located at esophagus near-end
When opening or its adjacent domain, the hand of operator will feel resistance, and now operator just stops promoting.In addition, operator is also
The sounding mark of apparatus of the present invention be can refer to estimate the depth of its insertion.
Now, operator can be inflated to the first air bag 61, and the first air bag 61 is filled with air, volumetric expansion, by pipe-line system
End be lifted up (if orthostatic position, it will be to lift forward).The first epiglottis at the top of pipe-line system pushes away therewith
Piece 3 is lifted, the pressure of the crook 90 of the upright crozier 9 of basal part will be departed from, and the elasticity of itself can be leaned on to stretch and stretch out
The distal openings of breather line 1, so as to which epiglottis be lifted, exposure glottis, the second air bag 62 then can be also inflated, in pipeline system
One pad is formed on the bottom of system distal end.This pad about in pars oralis pharyngis, is understood pipe-line system as longitudinal air bag gradually expands
