Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, the present invention provides a nasal cannula fixator, including an oxygen hose 1, a gas collecting tube 2, and an insertion tube 3. The oxygen hose 1 is located on the right side of the gas collecting tube 2, and the insertion tube 3 is located at the top of the gas collecting tube 2. Both the oxygen hose 1 and the insertion tube 3 are connected to the gas collecting tube 2. A positioning frame 4 is provided on the outside of the gas collecting tube 2. Elastic straps 5 are fixedly installed on the left and right sides of the bottom of the positioning frame 4. The other end of the elastic straps 5 is fixedly connected to a positioning component 6. An adjustment mechanism 7 is snapped into the surface of the gas collecting tube 2.

[0020] refer to Figure 3 The positioning component 6 includes a clamp 61, and a positioning protrusion 62 is fixedly connected to the front side of the inner wall of the clamp 61. The clamp 61 is made of stainless steel, and the positioning protrusion 62 is made of rubber.

[0021] As a technical optimization of this utility model, by setting the positioning component 6, after pulling the elastic bandage 5 to wrap around the patient's ear once, the elastic bandage 5 can be positioned by pressing the clip 61. At the same time, by pressing the positioning protrusion 62 into the concha cavity, the positioning effect of the clip 61 can be improved.

[0022] refer to Figure 2The adjustment mechanism 7 includes a positioning clamp 71, a fixing plate 72 is fixedly connected to the bottom of the surface of the positioning clamp 71, and a screw 73 is movably connected to the bottom of the fixing plate 72 through a shaft pin. The other end of the screw 73 passes through the positioning frame 4 and extends to the bottom of the positioning frame 4. The screw 73 is threadedly connected to the positioning frame 4. The positioning clamp 71 is made of PP material.

[0023] As a technical optimization of this utility model, by setting an adjustment mechanism 7, the PP material positioning clip 71 facilitates the user to position the air collection tube 2. By rotating the screw 73, the fixing plate 72 can be moved upward. The upward movement of the fixing plate 72 can move the positioning clip 71 and the air collection tube 2 inside it upward, thereby facilitating the user to insert the intubation tube 3 into the patient's nasal cavity.

[0024] refer to Figure 1 and Figure 2 The positioning frame 4 has a first through groove 8 on its front side, and the fixing plate 72 is fixedly connected to the front side of the connecting plate 9. The left and right sides of the connecting plate 9 are slidably connected to the left and right sides of the inner wall of the first through groove 8.

[0025] As a technical optimization of this utility model, by setting a first through groove 8 and a connecting plate 9, the vertical movement of the fixing plate 72 can drive the connecting plate 9 to move vertically inside the first through groove 8. At this time, the first through groove 8 can limit the movement of the connecting plate 9 and the fixing plate 72, thereby improving the stability of the movement of the fixing plate 72.

[0026] refer to Figure 1 Two limiting rings 10 are fixedly connected to the surface of the gas collecting pipe 2. The left and right sides of the positioning frame 4 are provided with second through grooves 11, and the inner wall of the second through grooves 11 is movably connected to the surface of the gas collecting pipe 2.

[0027] As a technical optimization of this utility model, by setting a limiting ring 10 and a second through groove 11, the two limiting rings 10 are located inside and on the right side of the positioning frame 4 respectively and fit into the positioning frame 4, thereby limiting the gas collecting pipe 2 and improving the stability of the gas collecting pipe 2 moving up and down.

[0028] refer to Figure 1 and Figure 2 An indicator plate 12 is fixedly connected to the front side of the connecting plate 9, a scale groove 13 is provided on the left side of the front side of the positioning frame 4, and a protective pad 14 is fixedly connected to the rear side of the positioning frame 4.

[0029] As a technical optimization of this utility model, by setting an indicator plate 12, a scale groove 13 and a protective pad 14, the up and down movement of the connecting plate 9 can drive the indicator plate 12 to move up and down. The scale groove 13 makes it easy for the user to control the depth of the insertion tube 3 into the patient's nasal cavity. The rear side of the positioning frame 4 is arc-shaped, and the protective pad 14 can prevent the positioning frame 4 from having hard friction with the patient's philtrum.

[0030] The working principle and usage process of this utility model are as follows: In use, first rotate the screw 73 to move the fixing plate 72 upward. The upward movement of the fixing plate 72 can move the positioning clip 71 and the gas collecting tube 2 inside it upward, so that the user can adjust the depth of the intubation tube 3 into the patient's nasal cavity as needed. Then, move the positioning frame 4 upward from the front of the patient's mouth to insert the intubation tube 3 into the patient's nasal cavity and make the back of the protective pad 14 fit against the patient's philtrum. Next, pull the two elastic straps 5 to wrap around the patient's ears one by one. Then, the elastic straps 5 can be positioned by pressing the clip 61. At the same time, the positioning effect of the clip 61 can be improved by pressing the positioning protrusion 62 into the concha cavity. Finally, oxygen can be delivered to the patient by connecting the oxygen hose 1 to the external oxygen supply device. The effect is good and it is convenient for the user to install and adjust the gas collecting tube 2.

[0031] In summary, this nasal cannula fixator, by setting a positioning frame 4 and an elastic band 5, allows the positioning frame 4 to limit the air collection tube 2 and the intubation tube 3. By pulling the elastic band 5 and making it wrap around the patient's ear, the positioning frame 4 can be positioned. This solves the problem that existing devices usually require the use of adhesive tape for auxiliary positioning during use. However, the adhesive tape is usually pasted on the skin of the patient's nose and nasal wings, and needs to be torn off when removing the device, which can cause discomfort or pain to the patient. In addition, the nose and nasal wings have a lot of oil secretion, which can easily reduce the positioning effect of the adhesive tape on the device, resulting in poor performance.
