[0022] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] See also Figures 1 to 4 The oxygen inhalation nasal catheter in the utility model comprises an airway tube 10, two nasal tubes 11 arranged side by side in the middle section of the airway tube 10, and oxygen supply branches 12 arranged at opposite ends of the airway tube 10, the oxygen supply branches 12 are connected to the nasal tubes 11, a fixing ring 21 is sleeved on the airway tube 10, the fixing ring 21 is between the two nasal tubes 11, a movable connecting seat 22 is fixed on the fixing ring 21, a connecting rod 23 is rotatably connected to the movable connecting seat 22, and a nose support structure 24 is provided at the end of the connecting rod 23.

[0027] The nose support structure 24 is mounted on the bridge of the patient's nose to help fix the airway tube 10. This is more stable than the prior art method of simply relying on the nasal plug tube 11 for fixation, and can effectively reduce the displacement or fall-off of the nasal cannula caused by the patient's activities or unconscious movements. Secondly, the connecting rod 23 can be rotated and adjusted relative to the movable connecting seat 22, so that the nose support structure 24 can adjust the fixed position according to the height of the nose bridge of different patients, thereby ensuring that the nose support structure 24 can be stably mounted on the bridge of the nose without being affected by the difference in the height of the nose bridge.

[0028] like Figure 2 and Figure 3As shown, the nose pad structure 24 includes a main frame 241, a connecting arm 242 and a nose pad 243. The main frame 241 is fixed to one end of the connecting rod 23, the connecting arms 242 are symmetrically arranged on both sides of the main frame 241, and the nose pad 243 is connected to the end of the connecting arm 242. In actual application, after the nasal plug tube 11 on the airway tube 10 is inserted into the patient's nasal cavity, the connecting rod 23 can be rotated until the nose pad 243 is mounted on both sides of the patient's nose bridge, thereby helping to fix the airway tube 10, so as to make up for the defect of the existing solution that the nasal plug tube 11 is simply fixed and easily loosened.

[0029] Furthermore, in this embodiment, the connecting arm 242 is an elastic arm, which can be made of plastic. It can be understood that the elastic characteristics of the elastic arm can apply appropriate close force when the two nose pads 243 are mounted on both sides of the nose bridge, thereby improving the fixing effect of the two nose pads 243 on the nose bridge, and it is less likely to fall off than directly mounting on the nose bridge.

[0030] For further information, see Figure 3 The fitting surface of the nose pad 243 is provided with a flexible pad 244. The flexible pad 244 can be made of soft silicone, and its main purpose is to increase the friction between the nose pad 243 and the skin, ensuring that the nose pad 243 can fit the bridge of the nose firmly. Secondly, the flexible pad 244 can also be used for buffering to reduce the pressure exerted by the nose pad 243 on the bridge of the nose, avoiding discomfort caused by long-term wearing.

[0031] See also Figure 2 The movable connection seat 22 includes a bracket 221 disposed on the fixing ring 21, and a rotating shaft 222 rotatably connected to the bracket 221. One end of the connecting rod 23 is fixedly connected to the rotating shaft 222, and the other end is fixedly connected to the main frame 241. It can be understood that the connecting rod 23 can rotate with the rotation of the rotating shaft 222, so as to adjust the fixed position of the nose support structure 24 according to the nose bridge height of different patients.

[0032] Furthermore, the connecting rod 23 is a curved shape adapted to the contour of the nose. It can be understood that the design follows the curve of the human nose, so that the nose pad 243 can fit the bridge of the nose more naturally, reducing the discomfort caused by shape mismatch, and this design helps to improve the comfort and stability of wearing.

[0033] like Figure 1 As shown, the two oxygen supply branches 12 are connected to an oxygen supply main pipe 14 through a catheter joint 13. The oxygen supply main pipe 14 is used to connect to an oxygen source to supply oxygen to the two oxygen supply branches 12 respectively.

[0034] See also Figure 1 and Figure 4The oxygen inhalation nasal catheter further includes a constricting member 31, the constricting member 31 having two side-by-side through-holes 32, and the oxygen supply branch tube 12 is passed through the through-holes 32. It can be understood that the constricting member 31 can slide along the oxygen supply branch tube 12, and according to different sliding distances, different degrees of constriction of the two oxygen supply branch tubes 12 can be achieved.

[0035] In actual application, when wearing an oxygen inhalation nasal cannula, the two oxygen supply branches 12 can be respectively passed behind the patient's ears and hung on the patient's ears, and then the constricting member 31 is slid until the constricting member 31 rests against the patient's chin. At this time, the infusion branch is fixed on the patient's facial contour.

[0036] For further information, see Figure 1 The two oxygen supply branches 12 are respectively connected with a tie 40. The tie 40 is used to tie the patient's head back position after the oxygen supply branch 12 is fixed, so as to further stabilize the fixing effect of the oxygen inhalation nasal catheter.

[0037] In summary, the oxygen nasal cannula in the above-mentioned embodiment of the utility model is mounted on the bridge of the patient's nose through the nose support structure 24, thereby helping to fix the airway tube 10. Compared with the prior art method of simply relying on the nasal plug tube 11 for fixation, it is more stable and can effectively reduce the displacement or fall-off of the nasal cannula caused by the patient's activities or unconscious movements. Secondly, the connecting rod 23 can be rotated and adjusted relative to the movable connecting seat 22, so that the nose support structure 24 can adjust the fixed position according to the height of the bridge of the nose of different patients, thereby ensuring that the nose support structure 24 can be stably mounted on the bridge of the nose without being affected by the difference in the height of the bridge of the nose.
