Abstract
The utility model discloses it is a kind of can auxiliary fiber bronchoscope intubation nasopharyngeal air duct, belong to a kind of nasopharyngeal air duct, including lumen ontology, lumen ontology both ends are connected by self-styled keel.Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, it is easy to use, it is convenient for deviating from device from Bronchofiberscope when in use, so as to make tracheal catheter lead into tracheae through Bronchofiberscope, the intubation difficulty of tracheae is effectively reduced, super tube efficiency is improved, is worthy to be popularized.
Description
Technical field
The utility model relates to a kind of nasopharyngeal air duct, it is specifically a kind of can auxiliary fiber bronchoscope intubation nasopharynx it is logical
Air flue.
Background technique
Nasopharyngeal air duct is inserted from nose, its tail end can reach near vocal cords, can be used as in anesthesia
Interim air flue is commonly used.In general anesthesia, carrying out trachea cannula with branchofiberoscope (referred to as: Bronchofiberscope) is a Xiang Ji
This operation, but operate more demanding！In new hand Anesthetist or the patient of difficult airway, Bronchofiberscope intranasal is difficult to insert
Enter intratracheally, so just wanting to borrow nasopharyngeal air duct as a channel, Bronchofiberscope is guided to enter tracheae.
Appurtenance of the nasopharyngeal air duct as trachea cannula in clinical anesthesia, can be applied to anesthesia in, anesthesia induction when
Or after general anesthesia revival, since nasopharyngeal air duct tail end can reach near glottis mouth, therefore it can effectively release Upper respiratory tract obstruction
Caused expiratory dyspnea.Simultaneously it have the characteristics that easy to operate, position be fixed well, ventilatory effect it is good.Especially some
In the patient of difficult airway, it is pre-filled with nasopharyngeal air duct, mask ventilation difficulty can be obviously improved；And branchofiberoscope exists
It can be easier to enter air flue under nasopharyngeal air duct auxiliary, but since nasopharyngeal air duct internal diameter will be much smaller than tracheal catheter outer diameter,
So cannot carry out under branchofiberoscope auxiliary in nasopharyngeal air duct through nasal intubation.
Thus those skilled in the art propose it is a kind of can auxiliary fiber bronchoscope intubation nasopharyngeal air duct, to solve
The problem of being proposed in above-mentioned background.
Utility model content
The purpose of this utility model is to provide it is a kind of can auxiliary fiber bronchoscope intubation nasopharyngeal air duct, to solve
The problems mentioned above in the background art.
To achieve the above object, the utility model provides the following technical solutions:
It is a kind of can auxiliary fiber bronchoscope intubation nasopharyngeal air duct, including lumen ontology, lumen ontology both ends
It is connected by self-styled keel.
As a further solution of the present invention: the self-styled keel and lumen ontology are PVC material.
Times of the self-styled keel siding no more than lumen body thickness as a further solution of the present invention,.
As a further solution of the present invention, one end of the lumen ontology extend outward closure after formed it is convex
Edge.
The self-styled keel and lumen ontology one-time injection molding as a further solution of the present invention,.
Compared with prior art, the utility model has the beneficial effects that the utility model structure is simple, easy to use, In
Convenient for deviating from device from Bronchofiberscope when use, so as to make tracheal catheter lead into tracheae through Bronchofiberscope, it is effectively reduced
The intubation difficulty of tracheae improves super tube efficiency, is worthy to be popularized.
Detailed description of the invention
Fig. 1 be it is a kind of can auxiliary fiber bronchoscope intubation nasopharyngeal air duct cross section structure schematic diagram；
Fig. 2 be it is a kind of can auxiliary fiber bronchoscope intubation nasopharyngeal air duct middle section deployed configuration schematic diagram；
Fig. 3 be it is a kind of can the nasopharyngeal air duct of auxiliary fiber bronchoscope intubation use so that structural schematic diagram.
In figure: 1- lumen ontology, the self-styled keel of 2-, 3- flange.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Embodiment one: please referring to Fig. 1-3, it is a kind of can auxiliary fiber bronchoscope intubation nasopharyngeal air duct, including lumen
Ontology 1,1 both ends of lumen ontology are connected by self-styled keel 2, when lumen ontology 1 is closed after the self-styled keel 2 in both ends are closed i.e.
The nasopharyngeal air duct for forming tubulose, is in broadband shape in addition to end after expansion, self-styled structure while ensuring sealing effect of keel 2
It is smaller better.
The self-styled keel 2 and lumen ontology 1 are PVC material.
1 one ends of the lumen ontology extend outward closure after formed flange 3.
Embodiment two: the present embodiment and the difference of a upper embodiment are: self-styled 2 width of keel is not more than lumen sheet
2 times of 1 thickness of body, the self-styled keel 2 and 1 one-time injection molding of lumen ontology.Self-styled dragon is given in the present embodiment
The further size of bone 2 limits, and self-styled keel 2 is avoided to influence the normal use of nasopharyngeal air duct, and disposable injection molding also can
Effectively improve processing efficiency.
Operation instruction: first inserting the device into nasal cavity, then will be inserted into the Bronchofiberscope of tracheal catheter by device outer end,
The self-styled keel 2 of tear-off device connection later, device is taken out from Bronchofiberscope, finally handles tracheal catheter well.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
