Preferably, the partition plate is arranged in the nasal vertical cavity channel, and the nasal vertical cavity channel is divided into two parts which are respectively communicated with the nasal oxygen tube and the horizontal cavity channel on the outer side through the partition plate.
Preferably, the plate surface of the partition plate is perpendicular to the central axis of the horizontal cavity.
Preferably, the partition plate is arranged on the central axis of the nasal cavity.
Preferably, one end of the partition board close to the nasal cavity opening is arranged on the inner side of the nasal cavity opening.
Preferably, two nasal cavity vertical channels are respectively provided with a partition plate, and a horizontal channel between the two partition plates is provided with a vent hole.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses mainly increased two improvement measures on the basis of current design. Firstly, the center of the horizontal section of the nasal oxygen tube is added with a vent hole, and secondly, the vertical interval is added at the part of the nasal oxygen tube which is placed into the nasal cavity. The horizontal section of the nasal oxygen tube is divided into a section with a hole in the middle and a section without holes on two sides by two vertical intervals, and the vertical section (part of the circular nasal oxygen tube) of the nasal oxygen tube entering the nose is divided into semicircular air tubes on the inner side and the outer side; the utility model can be used for improving the air flow blocking feeling and the drying feeling when the user uses the nasal oxygen tube.
The utility model discloses the air vent has been increased. According to the clinical practice experience, the nasal oxygen tube wearer always feels the nasal obstruction feeling and the nasal cavity is dry. This design can be with originally airtight partly nasal oxygen pipe and air intercommunication, and the gas that the person of wearing passed in and out the nasal cavity when breathing more is close the air current that the nostril inhaled under the physiological state inhales.
The utility model discloses increase perpendicular interval. Without this spacing, the perforated section would be isolated from the non-perforated section. The oxygen in the nasal oxygen tube leaks into the air, and the sufficient oxygen can not enter the nasal cavity of the wearer, so that the oxygen supply purpose can not be achieved. Increase this perpendicular interval, can prevent effectively that oxygen from revealing, make oxygen get into the nasal cavity through the outside semicircle pipe of the perpendicular section of nasal oxygen pipe to make the air get into the nasal cavity through the inboard semicircle pipe of the perpendicular section of nasal oxygen pipe.
The utility model discloses well vertical separation is not with the outer mouthful parallel and level of nasal oxygen tube vertical section. The design can ensure the plasticity of the vertical section and reduce the resistance when wearing; at the same time, the resistance of the wearer to exhale is reduced.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings:
as shown in fig. 1, the technical solution adopted by the present invention is to provide a nasal oxygen tube closer to the physiological airflow of the nose, wherein two nasal-entering vertical channels 1 entering the nasal cavity are arranged on the nasal oxygen tube, a section of horizontal channel 2 is arranged between the two nasal-entering vertical channels 1, and the horizontal channel 2 is provided with an air vent 4; a partition plate 3 is arranged between the horizontal cavity channel 2 and the nasal cavity vertical channel 1. Nasal oxygen tubes on two sides of the horizontal cavity 2 are arranged as outer nasal oxygen tubes 5, and a partition plate 3 for separating the outer nasal oxygen tubes 5 from the horizontal cavity 2 is arranged between the outer nasal oxygen tubes 5 and the horizontal cavity 2. The partition plate 3 is arranged in the nasal vertical cavity channel 1, and the nasal vertical cavity channel 1 is divided into two parts which are respectively communicated with the nasal oxygen tube 5 and the horizontal cavity channel 2 through the partition plate 3. The plate surface of the partition plate 3 is vertical to the central axis of the horizontal cavity 2. The partition plate 3 is arranged on the central axis of the nasal cavity 1. One end of the partition plate 3 close to the opening of the nasal cavity 1 is arranged at the inner side of the opening of the nasal cavity 1.
