Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The utility model provides a nasopharynx breather pipe for anesthesia, which comprises a breather pipeline 100 and a gas blocking device 200. The airway tube 100 is insertable into a human nasal cavity from a human nostril, and when the airway tube 100 is inserted into the human nasal cavity from the human nostril, the air inlet 210 of the airway tube 100 is capable of receiving air into the airway tube, and the air outlet 220 of the airway tube 100 is capable of directing air into the human nasal cavity and the human pharynx. The gas blocking device 200 is arranged on the path of the ventilation pipeline 100 through which the gas passes, and can reduce the flow speed of the gas, and can prolong the stay time of the gas in the nasal cavity of the human body. After the air is introduced into the nasal cavity of the human body through the air outlet 220 of the ventilation pipeline 100, the air blocking device 200 can realize that the air stays in the nasal cavity of the human body for a long time, the nasal mucosa can humidify the air staying in the nasal cavity and the humidification is sufficient, and when the air continues to flow downwards, respiratory tracts below the nose such as the pharynx, the throat and the like can keep moist. Meanwhile, the wet exhaled air can stay in the nasal cavity for a long time and then is discharged out of the human body, the humidifying effect of the nasal cavity on the inhaled air is further increased, the humidifying effect on the respiratory tracts such as the pharynx and the throat is better, and discomfort caused by dryness of the pharynx and the throat when an anesthesia patient uses the nasopharynx breather pipe is avoided. The air outlet 220 of the ventilation pipe 100 comprises an end air outlet 221 and an upstream radial through opening 222, the ventilation pipe 100 is further provided with a downstream radial through opening 230, and the upstream radial through opening 222 and the downstream radial through opening 230 penetrate through the pipe wall of the ventilation pipe 100 along the radial direction of the ventilation pipe 100. When the ventilation tube 100 is inserted into the human nasal cavity from the human nostril, the end air outlet 221 is communicated with the human pharynx, and the air flowing out of the upstream radial port 222 can enter the human nasal cavity. The gas blocking device 200 is located within the vent conduit 100 between the upstream radial port 222 and the downstream radial port 230. When the air enters the human nasal cavity through the air inlet 210, the air is blocked by the air blocking device 200, enters the human nasal cavity through the upstream radial port 222, then returns to the ventilation pipeline 100 from the human nasal cavity through the downstream radial port 230, and enters the human pharynx through the end air outlet 221. When the nasopharynx breather pipe is used for anesthesia and ventilation, gas needs to stay in the nasal cavity of a human body, the effect that the gas staying in the nasal cavity is humidified by the nasal mucosa is improved, the moistening of the pharynx, the throat and the like is further ensured, and the comfort level of a patient is improved.

As an alternative embodiment, the gas blocking device 200 is a plate-shaped structure, which can achieve better blocking of gas, avoid part of gas from directly entering the human body only through the ventilation duct 100, achieve long-time retention of inhaled gas in the nasal cavity, and make the nasal cavity more obvious in humidifying the inhaled gas.

As an alternative embodiment, the thickness of the gas barrier 200 is smaller than the wall thickness of the vent conduit 100, preferably made of a flexible film material. The smaller thickness of the gas barrier device 200 also achieves the same gas barrier effect and also facilitates the poking-off of the gas barrier device 200 as required. If the narcotized patient needs to suck the sputum, the corresponding sputum suction operation can be completed only by directly poking the gas blocking device 200 and inserting the sputum suction pipe.

As an alternative embodiment, the diameters of the upstream radial through opening 222 and the downstream radial through opening 230 are greater than the radius of the breather conduit 100 and less than the diameter of the breather conduit 100. When the diameters of the upstream radial port 222 and the downstream radial port 230 are larger, most of the tube wall of the ventilation tube 100 is of a hollow structure, so that the strength of the ventilation tube 100 is reduced, and the nasopharynx ventilation tube for anesthesia is inconvenient to insert into the nasal cavity of a patient; when the diameters of the upstream radial port 222 and the downstream radial port 230 are small, the nasopharyngeal airway for anesthesia causes gas flow obstruction, which is inconvenient for the patient to breathe.

As an alternative embodiment, the outside of the ventilation duct 100 is provided with a scale 240 and marked starting from 10CM, the scale counting the length starting from the air inlet 210. The nasopharynx breather pipe for anesthesia with the breather pipe 100 with different diameters (such as 0.5-2.5CM) and different lengths (such as 12-20CM) can be produced according to the needs, the scales are convenient for replacing the nasopharynx breather pipe for anesthesia according to the needs, and the application range of the nasopharynx breather pipe for anesthesia is improved. The depth of the nasal cavity of a human body is generally more than 10CM, and the mark from 10CM is satisfactory.

As an optional embodiment, the airway tube 100 is a three-layer woven catheter structure from inside to outside, and the inner airway tube layer 250 and the outer airway tube layer 270 are made of medical silica gel, so that comfort of human body experience can be guaranteed. The vent pipe intermediate layer 260 is braided wire, the braided wire is made of 304 stainless steel, the braided wire can enhance the overall strength of the vent pipe 100, and the effect that the vent pipe 100 is blocked and gas passes through is prevented from being influenced due to extrusion of external force.

As an alternative embodiment, the wall thickness of the end outlet 221 of the vent conduit 100 is greater than the wall thickness of the inlet 210 of the vent conduit 100. At the position of the ventilation pipeline 100 without the upstream radial through hole 222 and the downstream radial through hole 230, the wall thickness of the ventilation pipeline 100 is thickened, so that the wall thickness of the end air outlet 221 is larger than that of the air inlet 210, and unsmooth breathing caused by the fact that the pharynx presses and extrudes the ventilation pipeline 100 is avoided.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
