Specific embodiment
Such as in Fig. 1 ~ 4, a kind of quick device for building respiration channel again, including outer cylinder body 1 and center-pole 3, the one of center-pole 3
End is provided with point 301, and the lower end in such as Fig. 1, point 301 is used to be punctured, in preferred such as Fig. 7, using beveling
Point 301, puncture is better, and the other end is provided with shank 303, the upper end in such as Fig. 1, between point 301 and shank 303
The bar portion 305 of undergauge is provided with, as shown in Figure 4, point 301 is provided with collarette 302；
The bottom of outer cylinder body 1 is provided with multiple elasticity valves 101；
Center-pole 3 passes through the free end of outer cylinder body 1, elastic valve 101 to be located in collarette 302, due to the limitation of collarette 302, elasticity
Valve 101 can not open.
Device of the invention is suitable to：1. acute obstruction of upper respiratory tract.2. the laryngeal dyspnea such as serious water of diphtheria, larynx
Swell.3. Head And Face severe trauma.4. trachea cannula have taboo or the state of an illness it is urgent and when needing quick open airway.
Using the position for preceding needing first to determine ring first film, ring first film is located between thyroid cartilage and annular cartilage, front nothing
Hard to block tissue, only soft thyroid gland passes through, and tracheae is after ring first film.Ring first film is relatively thin, around without critical position,
Therefore respiration channel is built again generally to be punctured herein.If oneself find, can bow, then along Adam's apple most highlight to
Under lightly touch, have a depression just like soya bean size in about 2 ~ 3 centimeters, referred to herein as where ring first film location.When using, suffer from
Person's dorsal position, head layback, after partly sterilised patient with forefinger middle finger stationary ring cartilage both sides, by the point of apparatus of the present invention
301 are pierced into ring first film, have the sense that falls through due to being hollow tracheae after ring first film, therefore after puncture, and applying patient can think that resistance is dashed forward
So disappear.As shown in Figure 6, the shank 303 of center-pole 3 is pressed, point 301 moves ahead, the free end of elastic valve 101 is from collarette
Depart from 302 and open, center-pole 3 is exited from outer cylinder body 1, urgent respiration channel is set up.Later stage according to circumstances can be from outer barrel
Body 1 inserts tracheal catheter, is not required to carry out trachea puncture operation again.
In preferred scheme such as Fig. 1,2, the internal diameter of the external diameter less than outer cylinder body 1 of collarette 302, the free end of elastic valve 101
When in collarette 302, a structure for gradually undergauge is formed in the axial region of elastic valve 101.Thus structure, is easy to center-pole
3 exit.
In preferred scheme such as Fig. 1,2, spacing ring 2 is provided between the end face of shank 303 and outer cylinder body 1.Thus structure,
It is easy to limit the axial location of center-pole 3, it is to avoid when unused, the abjection from collarette 302 of elastic valve 101.
In preferred scheme such as Fig. 1,2, tearing notch 21 is provided with spacing ring 2, for quickly tearing, so as to remove spacing ring
2.The structure removed can also be easy to using other, for example, spacing ring 2 is the structure of spiral package, when using, package is pulled open i.e.
Desirable lower limit ring 2.Or using the structure of Half ring, the Half ring of two halves together with snapping connection, is used by hinge
When, opening buckle can quickly remove spacing ring 2.
In preferred scheme such as Fig. 1,2,6, the structure of described elastic valve 101 is：It is provided with many along the circumference of outer cylinder body 1
Individual elongated slot, forms the structure of elastic valve 101 between elongated slot, circular hole 102 is provided with the end of elongated slot, when the freedom of elastic valve 101
When holding unconstrained, elastic valve 101 opens.Elastic valve 101 during fabrication, using spring steel, sets the prestressing force of outer, in order to
Maintain respiration channel.
In preferred scheme, the internal diameter of the internal diameter more than outer cylinder body 1 of the elastic valve 101 for opening.Thus structure, is easy to center
The point 301 of bar 3 passes through.
In preferred scheme such as Fig. 1,4, at least one air inlet 306 is provided with point 301, gas is provided with center-pole 3
Road 307, air flue 307 is connected with air inlet 306；
Exhaust outlet 304 is provided with shank 303, exhaust outlet 304 is set to the structure of tone whistle.Thus structure, when being vented in puncture process
After mouth 304 enters into tracheae, gas is to discharge or enter from exhaust outlet 304, now produces birdie in the structure of tone whistle, so that
There is no the personnel of puncture experience to be able to know that to puncture successfully yet.
In another preferred scheme such as Fig. 1,2, slip stop collar 5 is socketed with outside outer cylinder body 1, slides stop collar 5 and be provided with
The collar 51 and expanding seam portion 52.By setting a plurality of position line for different age group on outer cylinder body 1, will slide
Stop collar 5 slides into the position of corresponding position line, so that paracentesis depth is limited, so as to also can without the personnel of systematic training
Use.Stop collar 5 is slided to be engaged with the structure of air flue 307, it is better.
In preferred scheme such as Fig. 5, it is provided with limiting card 308, outer cylinder body 1 in center-pole 3 and is provided with wedge portion 103, limiting card
Spring 4 is provided between 308 and wedge portion 103, wedge portion 103 is located at the lower section of limiting card 308, so that when elastic valve 101 from collarette 302
After deviating from and opening, center-pole 3 can quickly be deviate from.It is further preferred that being provided with breach in the position of collarette 302, it is easy to make
Wedge portion 103 passes through, to avoid the diameter of outer cylinder body 1 excessive.
In preferred scheme such as Fig. 3, described outer cylinder body 1 is socketed with slip using the structure of winding outside outer cylinder body 1
Stop collar 5.Stop collar 5 is slided herein except for limiting paracentesis depth, also individual effect is exactly the winding knot for constraining outer cylinder body 1
Structure.Slip stop collar 5 is removed, i.e., can easily remove outer cylinder body 1, for tracheal catheter of the part with expanding structure.
It is further preferred that being provided with tearing port on stop collar 5 is slided, it is easy to quickly remove slip stop collar 5, so that then removal volume
Around the outer cylinder body 1 of structure.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, mutual
On the premise of not conflicting, every technical characteristic that the present invention is recorded can be combined with each other.Protection scope of the present invention should be with right
It is required that the equivalents of technical characteristic are protection model in the technical scheme recorded, including the technical scheme of claim record
Enclose.Equivalent i.e. within this range is improved, also within protection scope of the present invention.
