A kind of trachea cannula
Technical field
The utility model relates to medical instruments field more particularly to a kind of trachea cannulas.
Background technique
Trachea cannula is used to be patient ventilating, after existing trachea cannula is inserted into patient's trachea from throat, then with frenulum system
Then firmly trachea cannula ties up to frenulum on patient's neck, by the scale on trachea cannula, medical staff can be accurately held
The depth of trachea cannula insertion.But this fixed form has the following problems: first is that trachea cannula outer wall is smooth, frenulum is not allowed
It easily fastens, is easy to appear trachea cannula shifting phenomena;Second is that needing to unlock, rushing again when needing to adjust trachea cannula insertion depth
Tie-down frenulum is washed, it is troublesome in poeration.
Utility model content
The utility model is intended to provide trachea cannula, and casing is arranged on trachea cannula, anti-by being arranged in sleeve outer wall
Cunning portion, position of the mobile casing on trachea cannula are fixed not firm enough to solve existing trachea cannula, adjust depth not side
Just the problem of.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows: a kind of trachea cannula, including intubation is originally
Body is intubated on ontology and is set with casing, internal surface of sleeve pipe and intubation body outer wall clearance fit, if the intubation body outer wall is equipped with
Dry along intubation ontology, axially equally distributed protrusion, internal surface of sleeve pipe are equipped with several grooves being axially distributed along casing, groove
It is adapted with protrusion, the spacing of the upward adjacent grooves of quill is equal with the intubation spacing of the upward adjacent protrusion of body shaft, intubation
For raised quantity on ontology axial direction more than the number of recesses in casing axis direction, sleeve outer wall is equipped with anti-slip part.
At least two protrusions are evenly distributed on the same circumference of the intubation body outer wall, on the same circumference of internal surface of sleeve pipe
At least two grooves are evenly distributed with, the same circumference fovea superior slot number of internal surface of sleeve pipe and the same circumference of intubation body outer wall are convex
It is identical to play quantity.
The protrusion is spherical shape.
The anti-slip part is anti-skid chequer or annular groove or frosted.
The distributed areas of the protrusion are 40-60mm in the upward length of intubation body shaft, and described sleeve pipe axial length is
30mm。
The proximal end of the distributed areas of the protrusion is at the 190-210mm scale of intubation ontology.
The intubation body proximal end outer wall is equipped with air bag, and intubation body distal end is equipped with gas tube, is intubated this body sidewall and is equipped with
Filling channel, the both ends of filling channel are respectively communicated with air bag, gas tube.
The utility model is not only able to prevent trachea cannula from shifting, and also has and medical staff is facilitated to adjust trachea cannula insertion
The effect of patient's trachea depth.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is intubation ontology part and casing cross-sectional view;
Fig. 3 is that the utility model uses schematic diagram.
In figure: 1- is intubated ontology, 2- casing, 3- protrusion, 4- groove, 5- anti-slip part, 6- frenulum.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
" proximal end " described herein is close to one end of heart, and " distal end " is one end far from heart.
As shown in Figure 1 and Figure 2, a kind of trachea cannula, including intubation ontology 1, the 1 proximal end outer wall of intubation ontology are equipped with gas
Capsule, intubation 1 distal end of ontology are equipped with gas tube, and intubation 1 side wall of ontology is equipped with filling channel, and the both ends of filling channel are respectively communicated with gas
Capsule, gas tube;The proximal end of the intubation ontology 1 is intubation ontology 1 close to one end of heart, and 1 distal end of intubation ontology is slotting
The one end of tube body 1 far from heart.
Casing 2,2 inner wall of casing and intubation 1 outer wall clearance fit of ontology, the intubation ontology 1 are set on intubation ontology 1
Outer wall is equipped with several along intubation ontology 1 axial equally distributed raised 3, and 2 inner wall of casing is equipped with several along axial point of casing 2
The groove 4 of cloth, groove 4 are adapted with protrusion 3, and the spacing and intubation ontology 1 of the axial upper adjacent grooves 4 of casing 2 are axial adjacent
The spacing of protrusion 3 is equal, is intubated 4 quantity of groove that 3 quantity of protrusion on 1 axial direction of ontology is more than on 2 axis direction of casing,
2 outer wall of casing is equipped with anti-slip part 5.
Raised 3 there are two being uniformly distributed on the same circumference of intubation 1 outer wall of ontology, on the same circumference of 2 inner wall of casing
Groove 4 there are two being uniformly distributed.
Described raised 3 be spherical shape.
The anti-slip part 5 is anti-skid chequer or annular groove or frosted.
Length of raised 3 distributed areas in intubation 1 axial direction of ontology is 40-60mm, the preferred 40mm of this example, institute
Stating 2 axial length of casing is 30mm.
At the 190-210mm scale of intubation ontology 1, the present embodiment is preferred for the proximal end of raised 3 distributed areas
At 210mm scale.
In use, as shown in figure 3, making groove 4 be interlocked with protrusion 3, according to patient on intubation ontology 1 for 2 sets of casing
Actual needs, position of the adjustment casing 2 on intubation ontology 1, then tied up in the anti-slip part 5 on 2 outer wall of casing with frenulum 6 so that
Casing 2 is fixed with patient's neck, and then guarantees that the position of intubation ontology 1 is fixed.
Certainly, the utility model can also have other various embodiments, without departing substantially from the spirit of the present invention and its essence
In the case of, those skilled in the art can make various corresponding changes and modifications, but these phases according to the utility model
The change and modification answered all should belong to the protection scope of the utility model the attached claims.
