Accompanying drawing explanation
Fig. 1 is the front view of the oropharyngeal airway of a kind of embodiment of this utility model；
Fig. 2 is the side view of the oropharyngeal airway of a kind of embodiment of this utility model；
Fig. 3 is the top view of the oropharyngeal airway of a kind of embodiment of this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1～3 show schematically show the oropharyngeal airway according to a kind of embodiment of the present utility model.As schemed
Showing, including bite-block 1 and the orophynged airway 2 that is connected with bite-block 1, bite-block 1 is provided with sputum suction hole 3 and oxygen supply hole 4, sputum suction hole 3
For external suction pump, oxygen supply hole 4 extends along orophynged airway 2 for external respirator, sputum suction hole 3 and oxygen supply hole 4, is formed
Running through suction sputum passage 5 and the oxygen supply passage 6 of bite-block 1 and orophynged airway 2, bite-block 1 is additionally provided with gastroscope access apertures 7.
During this oropharyngeal airway of Clinical practice, it is pharyngeal that orophynged airway 2 stretches into patient, utilizes its flexibility so that enter
Enter narcose patient's root of the tongue and leave pharynx rear wall, release airway obstruction, so that gastroscope can be by the gastroscope on bite-block 1
Access apertures 7 enters smoothly and checks in the patient, and meanwhile, patient teeth bites bite-block 1, it is to avoid dental articulation causes oral cavity soft
Tissue injury and orophynged airway 2 and the flat of gastroscope conduit close, it addition, this oropharyngeal airway be additionally provided with run through oropharynx lead to
The suction sputum passage 5 of airway 2 and bite-block 1 and oxygen supply passage 6, therefore, in use, it is possible to according to patient's practical situation and
Shi Jinhang oxygen supply and suction sputum operation.Bite-block 1, orophynged airway 2 and gastroscope are passed through by oropharyngeal airway of the present utility model
Hole 7 combines, it is to avoid patient is when carrying out gastroscopy, because of the respiratory tract obstruction situation such as glossoptosis or respiration inhibition
And cause gastroscope cannot enter stomach from patient oral cavity, it is ensured that the ease for operation of gastroscopy, additionally, suction sputum passage 5
Setting with oxygen supply passage 6 can give patient's oxygen supply and suction sputum in time, it is to avoid patient occurs anoxia during clinical examination, stops up
The situations such as breath occur.
The outward flange of bite-block 1 is provided with groove 8, is engaged for patient, and the outer edge surface of bite-block 1 is smooth.Using should
During oropharyngeal airway, patient really bites at the outer peripheral groove of bite-block 18, owing to the bite-block 1 diameter in groove 8 both sides is equal
More than the diameter at bite-block 1 groove 8, therefore, when patient bites at the groove 8 of bite-block 1, bite-block 1 is near orophynged airway 2
Side can be stuck in the upper jaw and the lower jaw of patient, prevent in checking process, patient spues bite-block 1, and bite-block 1 is led away from oropharynx ventilation
The side of pipe 2 can be stuck in lip, prevents in checking process, and patient gulps down bite-block 1 by mistake, and therefore the design of groove 8 breaches biography
The bite-block design of system, significantly ensure that the fairness of clinical examination, at utmost reduces patient and gulp down the risk of bite-block by mistake, strengthen
The serviceability of this utility model.It addition, the outer edge surface of bite-block 1 is smooth so that the oral cavity of patient will not be made by bite-block 1
Become damage, improve its safe application performance.
Bite-block 1 is in ellipticity.Bite-block 1 is designed to ellipticity, meets the oval shape of people on the whole, ensure painless stomach
While spectroscopy is smoothed out, greatly reduce sense of discomfort when patient bites bite-block 1.
Orophynged airway 2 and oxygen supply passage 6, suction sputum passage 5, bite-block 1 are one-body molded.When orophynged airway 2, oxygen supply
If passage 6, suction sputum passage 5 and the one-body molded design of bite-block 1, on the one hand, when avoiding the use of this utility model, oropharynx leads to
Airway 2 departs from bite-block 1, or oxygen supply passage 6 and suction sputum passage 5 send the situations such as skew and occur, and affect the suitable of clinical examination
Profit is carried out, and improves ease of use and the safety of this oropharyngeal airway, on the other hand, reduces production cost, Yi Jijia
Work difficulty.
Bite-block 1 connects flexible fixing band 9 away from the side of orophynged airway 2, for bite-block 1 is fixed on patient's head
Portion.After patient bites bite-block 1, by elastic reducing-fixing band 9 bite-block 1 is fixed on patients head, thus avoid bite-block 1 and with
The orophynged airway 2 being connected offset, and avoid gastroscope access apertures 7 to be subjected to displacement, be further ensured that clinical examination
It is smoothed out.
Bite-block 1 uses flexible glue to make.Flexible glue has certain flexibility, if using flexible glue to make bite-block 1 so that patient
When biting bite-block 1, tooth will not be caused damage by bite-block 1, and improves the comfort level of patient；It addition, flexible glue has stable
Chemical property and physical and mechanical properties, be difficult to aging, safety coefficient is high, and service life is long, is especially suitable for making bite-block 1.
Orophynged airway 2 uses medical plastic to make.Medical plastic light weight and firm, safe and sanitary index is high and
There is certain elasticity, if using medical plastic to make orophynged airway 2, be conducive to improving making of orophynged airway 2
By wholesomeness and robustness so that patient can relieved use.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into this practicality
Novel protection domain.
