Referring to fig. 1, the present utility model provides an oropharyngeal airway.

The oropharyngeal airway comprises an airway body 100 and an air bag 200, wherein a gas channel for providing oxygen for a patient is arranged in the airway body 100, one end of the airway body 100 corresponding to the gas channel is used for being communicated with a respirator, and the other end is used for being inserted into the throat of the patient; the airbag 200 is provided to the vent pipe body 100, and the airbag 200 is switchable between an inflated state and a deflated state; the balloon 200 is in the inflated state to deploy the patient's larynx while the balloon 200 is positioned between the patient's tongue root and larynx.

Specifically, vent body 100 may be cylindrically configured, although other shapes are possible. The ventilator may be used to vent oxygen into the gas passages of the vent tube body 100 such that oxygen may enter the patient's mouth through the gas passages inside the vent tube body 100. The airbag 200 can be inflated in various ways, so that the airbag 200 can switch between an inflated state and a contracted state according to the needs of a patient. In the initial state, the air bag 200 is in a contracted state, and when the oropharyngeal airway is required to be used, the oropharyngeal airway in the contracted state is partially extended into the patient's mouth while the air bag 200 on the oropharyngeal airway is inflated, so that the air bag 200 can prop open the patient's throat. For example: in a non-general anesthesia state, the patient breathes spontaneously, the breathing frequency is very weak, suffocation caused by the suffocation of the tongue root easily occurs, at this time, the oropharynx breather pipe stretches into the mouth of the patient, the space between the tongue root and the throat is expanded through the air bag 200, and the suffocation can not occur due to the suffocation of the tongue root of the patient, so that the patient breathes better.

Referring to fig. 1, in the present embodiment, the airbag 200 is connected to an inflation tube 300, and the inflation tube 300 is used to inflate the airbag 200, so that the airbag 200 is switched back and forth between an inflated state and a deflated state. Specifically, the air tube 300 has a small tube, which may be connected to the inside of the air bag 200 through the vent tube main body 100, and the air tube 300 may be inflated to the inside of the air bag 200 through the connection with an external device to be in an inflated state, so as to prop open the throat of the patient, so that air more smoothly enters the lungs of the patient, and the patient breathes better. Of course, the gas may be stored in advance in the inflation tube 300, and the gas may be pushed by hand to flow into the air bag 200, and when the air bag 200 is in the inflated state, the sealant is sealed to make the gas stay in the air bag 200 all the time, and the air bag 200 keeps the inflated state to open the throat of the patient.

Referring to fig. 1, in the present embodiment, the inflation tube 300 is connected to an injector, and the injector is used for injecting gas into the inflation tube 300, so that the airbag 200 is in the inflated state. Of course, in other embodiments, other devices may be used to inject gas into bladder 200.

Referring to fig. 1, in this embodiment, the gas tube 300 is provided with a one-way valve, and the one-way valve is used to control the on/off of the gas channel inside the gas tube 300. Specifically, the one-way valve is that fluid can only flow along the inlet to the outlet, but the outlet cannot flow back, so that air can be prevented from flowing reversely, the air bag 200 can be kept in an inflated state all the time, and the service performance of the air bag 200 is improved. For example: when the air bag 200 is required to be inflated, the one-way valve can be opened, so that the air gradually flows into the air bag 200, and when the air bag 200 is full of the air, the one-way valve is closed, so that the air bag 200 is kept in an inflated state.

Referring to fig. 1, in this embodiment, an air inlet end 110 corresponding to the air passage and used for communicating with the respirator is provided at one end of the breather pipe body 100, the air inlet end is provided with an external connection port 400, and the air inlet end 110 is communicated with the respirator through the external connection port 400. It can be appreciated that the respirator directly transmits air to the air inlet end 110 of the air channel in the breather pipe main body 100 through the external connection interface 400, and the external connection interface 400 can be connected with a breathing ball, so that the external connection interface 400 can be conveniently connected.

Referring to fig. 1, in the present embodiment, the pipe diameter of the external connection interface 400 is 14 to 15 mm. For example: the external interface 400 may have a pipe diameter of 15 mm to fit the size of an existing respirator.

Referring to fig. 1, in this embodiment, an end of the vent pipe body 100 corresponding to the gas channel for being inserted into the throat of a patient is an air outlet end 120, and the air bag 200 is disposed on the peripheral wall of the vent pipe body 100 near the air outlet end 120. By arranging the air bag 200 close to the air outlet end 120, the oropharynx breather pipe is not too deep to be inserted into the throat of a patient when the patient uses the oropharynx breather pipe, so that the patient is prevented from being wounded.

Referring to fig. 1, in the present embodiment, the vent pipe body 100 has an insertion portion between the outlet end 120 of the gas channel and the airbag 200, and the length of the insertion portion is 2 to 3 mm. It will be appreciated that when the oropharyngeal airway is inserted into the patient's mouth, the front end of the oropharyngeal airway does not enter the glottis nor the lungs, but simply remains in the patient's throat to deliver oxygen, and the oropharyngeal airway is not invasive to the patient.

Referring to fig. 1, in the present embodiment, the surface of the airbag 200 is curved when the airbag 200 is in the inflated state. When the vent pipe main body 100 enters the mouth of a patient, the air bag 200 is inflated to expand the throat of the patient, the air bag 200 is arranged in a shape of an ellipsoid from the appearance, the air bag 200 contacted by the patient is free of sharp corners due to the arc-shaped surface of the air bag 200, the stress is reduced, and the treatment comfort of the patient is improved.

Referring to fig. 1, in the present embodiment, the airbag 200 is made of a soft material. In this manner, inflation of the balloon 200 is facilitated. Meanwhile, in the present embodiment, the airbag 200 may also be made of a transparent material.

The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
