Common symptoms of rhinitis include nasal obstruction, nasal itching, nasal discharge and sneeze, which are accompanied by complications such as hyposmia, throat itching, headache and the like, and severe cases can cause sphagitis, tracheitis, otitis media and asthma. Allergic rhinitis is accompanied by itching eyes, red, swelling and pain of nasal wings and nasal tips, etc.
Pharyngitis is nonspecific inflammation of pharynx, is a common name for inflammation caused by infection of pharynx by various microorganisms, and can exist alone, be concurrent with rhinitis, tonsillitis and laryngitis, or be a precursor symptom of some diseases. The clinic can be divided into acute pharyngitis and chronic pharyngitis. Typical symptoms include pharyngeal discomfort, pain, itching or dryness, burning sensation, smoking sensation, foreign body sensation, pharyngalgia, nausea, irritating cough, expectoration of secretions, severe cases with aversion to cold, high fever, headache, general discomfort, inappetence, dysphagia, dyspnea, and accompanying back and limb soreness, ear pain, tongue root lymphoid tissue inflammation, ear distress, tinnitus, and re-hearing.

Detailed Description
In order to provide an implementation scheme for reducing adverse effects of nasal exhaled air on treatment and equipment, the embodiments of the present application provide a nasal breathing device and rhinitis treatment apparatus, and the following description of the preferred embodiments of the present application with reference to the accompanying drawings is to be understood that the preferred embodiments described herein are merely for illustration and explanation of the present application, and are not intended to limit the present application. And embodiments and features of embodiments in this application may be combined with each other without conflict.
Embodiments of the present application provide a nasal breathing apparatus, as shown in fig. 1-3, comprising: a gas delivery channel 1 and two double-layer cylinders 2 arranged side by side, wherein the tail ends of the double-layer cylinders 2 are used for aligning nostrils in use;
the double-layered cylinder 2 includes an outer cylinder 21 and an inner cylinder 22, the inner cylinder 22 being located inside the outer cylinder 21;
a nasal cavity air inlet channel 3 formed between the wall of the outer cylinder 21 and the wall of the inner cylinder 22 is communicated with the air inlet channel 1, the air inlet channel 1 is used for being connected with an air pipe of an external device, and air generated by the external device sequentially enters the nasal cavity through the air pipe, the air inlet channel 1 and the nasal cavity air inlet channel 3;
the base 221 and the tip 222 of the inner cylinder 22 are both open, and the gas exhaled from the nasal cavity is discharged out of the nasal breathing device through the nasal exhalation passageways 4 formed by the inner cylinder 22.
The above-mentioned nose breathing apparatus that this embodiment provided adopts the design of double-deck drum, has set up the nasal cavity air inlet channel that is used for specially to the nostril gas transmission to and be used for the nasal cavity breathing channel of the exhalant gas of discharge nasal cavity specially, through the design of this binary channels, can more effectual exhaust nasal cavity exhalant gas, reduce the exhalant gas that gets into gas transmission channel, also reduced the pollution of exhalant gas to gas transmission channel and external device, thereby reduced the gas that the nasal cavity exhales to the bad influence that treatment and equipment produced.
In the nasal breathing apparatus, an annular space is formed between the wall of the outer cylinder 21 and the wall of the inner cylinder 22, and is communicated with the gas delivery passage 1, as the nasal cavity gas inlet passage 3, the passage space formed by the inner cylinder 22 is used as the nasal cavity gas outlet passage 4, and both the base end 221 and the tip end 222 of the inner cylinder 22 are opened, that is, both ends are opened, and the nasal cavity gas inlet passage 3 and the nasal cavity gas outlet passage 4 are different passages. In the process of using the nasal breathing device, the tail ends of the two double-layer cylinders 2 are aligned to nostrils, gas (hot steam, atomized steam and the like) generated by an external device enters the gas transmission channel 1 through the channel inlet 5 of the gas transmission channel 1, and enters the nasal cavity in a spiral flow state in the nasal cavity air inlet channel 3 of the annular space after passing through the gas transmission channel 1, and as the two ends of the nasal cavity air outlet channel 4 are opened, the gas exhaled by the nasal cavity can be discharged out of the nasal breathing device through the nasal cavity air outlet channel 4 formed by the inner cylinder 22, and the gas exhaled by the nasal cavity basically does not enter the gas transmission channel through the nasal cavity air inlet channel and does not enter the external device (such as a treatment host), so bacteria and viruses carried by the gas exhaled by the nasal cavity can be effectively reduced, and the accumulation and breeding in each channel of the treatment host can be effectively reduced, and the treatment effect can be further improved.
In one embodiment of the present application, further, the gas delivery channel 1 may be a slope channel, and its slope range may be 30% -75%, and by adopting the design of the slope channel, the gas may be guided to more smoothly enter the outlet of the gas delivery channel 1 and enter the nasal cavity air inlet channel 3.
In one embodiment of the present application, further, the base end 211 of the outer cylinder 21 is tapered toward the tip end 212, and the diameter ratio of the base end 211 and the tip end 212 of the outer cylinder 21 is 3:2.
In one embodiment of the present application, further, the base end 221 of the inner cylinder 22 is tapered toward the tip end 222, and the diameter ratio of the base end 221 and the tip end 222 of the inner cylinder 22 is 3:2.
The diameters of the outer cylinder 21 and the inner cylinder 22 are gradually reduced from the base end to the tail end, so that the gas can form certain pressure after entering the nasal cavity air inlet channel 3, and the gas can enter the deep part of the nasal cavity more easily, thereby exerting better treatment effect.
In one embodiment of the present application, further, the length of outer cylinder 21 exceeds the length of inner cylinder 22 by 10% -20%. Since the inner cylinder 22 and the outer cylinder 21 are coaxial and the tip 222 of the inner cylinder 22 is shorter than the tip 212 of the outer cylinder 21, even when the gas in the annular nasal cavity intake passage 3 stops being generated for some reason, it can be returned into the inner cylinder 22 from the opening of the tip 222 of the inner cylinder 22 and discharged to the outside from the opening of the base end 221 of the inner cylinder 22 after reaching the tip 212 of the outer cylinder 21. That is, even when the injection of the gas is stopped, the gas itself continues to flow, thereby preventing accumulation in the nasal cavity intake passage 3, and the gas continues to flow, avoiding rising to a higher temperature, and also preventing a large amount of gas from being blown out at one time.
In one embodiment of the present application, further, the diameter ratio of the same vertical cross section of the outer cylinder 21 and the inner cylinder 22 may be 2:5.
The embodiment of the application also provides a rhinitis therapeutic apparatus, which comprises: any of the nasal breathing devices described above.
