[0020] As shown in the attached figure, the present invention includes a connector 1, a nasal plug 2, and a pair of nasal cannulas 3 connecting the connector 1 and the nasal plug 2. The two ends of the nasal plug 2 are respectively provided with fixing plates 4, and a silicone patch 5 is provided at the bottom of the fixing plate 4.

[0021] Connector 1 is a universal connector used to connect to the output tube of the oxygen inhalation device. Both the fixing plate 4 and the silicone patch 5 are rectangular structures. The area of ​​the silicone patch 5 is larger than that of the fixing plate 4. When in use, the silicone patch 5 extends out of the fixing plate 4 on all sides and is attached to the upper part of the cheeks on both sides of the nose to fix the position of the nasal plug 2 and prevent the nasal plug 2 from loosening and falling off due to the baby's shaking.

[0022] The fixing plate 4 is 2mm thick and has good flexibility. The silicone patch 5 is a high-transparency and high-tear-resistance silicone sheet with a thickness of 1mm, which can perfectly fit the shape of the face.

[0023] Furthermore, the nasal plug plug 2 is provided with nasal cannula connection parts 6 at both ends, and one end of the nasal cannula 3 is provided with a plug 7 that cooperates with the nasal cannula connection parts 6.
