Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4 The improved high-flow fixing belt shown in the figure comprises two first nasal oxygen tubes 8 and a delivery block 1 and two second nasal oxygen tubes 4 arranged on one side of the delivery block 1, the two first nasal oxygen tubes 8 are ordinary nasal oxygen tubes, and the second nasal oxygen tube 4 is a high-flow nasal oxygen tube dedicated to a transnasal high-flow machine. Both sides of one side of the surface of the delivery block 1 are fixedly connected with fixing blocks 5, and one side of the two fixing blocks 5 is provided with fixing components 10 for fixing the two first nasal oxygen tubes 8 to the two fixing blocks 5. The tube walls of the two first nasal oxygen tubes 8 are jointly provided with a fastening component 11 for adjusting the use length of the two first nasal oxygen tubes 8 so that the second nasal oxygen tube 4 is tightly fitted to the patient's nasal cavity. By using the first nasal oxygen tubes 8 instead of the traditional fixing belt to fix the transnasal high-flow machine, the weight of the pipe borne by the patient is reduced, and pressure damage to the patient's skin is avoided when the transnasal high-flow machine is used for a long time. At the same time, the manufacturing method is simple and the manufacturing cost is low, so that the practicality of the utility model is high.

[0022] like Figure 2 and Figure 3 As shown, the fixing component 10 includes a mounting block 1001, which is used to fix the first nasal oxygen tube 8. One end of the mounting block 1001 is fixedly connected to one end of the first nasal oxygen tube 8, and the other end of the fixing component 10 is fixedly connected to a plug-in rod 1002. The top of the plug-in rod 1002 is fixedly connected to a limiting block 1003. The limiting block 1003 cooperates with the fixing hole 6 so that the first nasal oxygen tube 8 can be connected to the fixing block 5, and can achieve the effect of easy installation. The limiting block 1003 and the plug-in rod 1002 are jointly provided with a functional groove 1004.

[0023] like Figure 2and Figure 4 As shown, the fastening assembly 11 includes a fastening block 1101 and two fastening holes 1102 opened on the top surface of the fastening block 1101. The inner walls of the two fastening holes 1102 are respectively slidably connected to the tube walls of the two first nasal oxygen tubes 8. The limit block 1003 is semicircular in shape. The diameter of the limit block 1003 is larger than the plug-in rod 1002. The limit block 1003 and the plug-in rod 1002 are both made of rubber.

[0024] like Figure 1 and Figure 2 As shown, the ends of the two first nasal oxygen tubes 8 are fixedly connected with limiting balls 9, which can prevent the two first nasal oxygen tubes 8 from being separated from the fastening block 1101. The diameters of the two limiting balls 9 are larger than the two fastening holes 1102. Soft pads 7 are sleeved on the tube walls of the two first nasal oxygen tubes 8. The two soft pads 7 can separate the two first nasal oxygen tubes 8 from the patient's skin during use to prevent the two first nasal oxygen tubes 8 from causing damage to the patient's skin. The inner walls of the two soft pads 7 are slidably connected to the tube walls of the two first nasal oxygen tubes 8, respectively.

[0026] Working principle of the utility model: when the improved high-flow fixing belt is used, the connector 3 is first connected to the nasal high-flow machine, and then the two limit blocks 1003 are inserted into the two fixing holes 6, so that the two first nasal oxygen tubes 8 are fixed to the two fixing blocks 5, and then the two second nasal oxygen tubes 4 are respectively inserted into the two nostrils of the patient, and then the first nasal oxygen tube 8 is placed above the patient's ears, and then it bypasses the back of the two ears and extends to the lower jaw, and the two soft pads 7 are moved on the tube walls of the two first nasal oxygen tubes 8. Move to the contact position between the two first nasal oxygen tubes 8 and the two ears to prevent the two first nasal oxygen tubes 8 from rubbing against the two ears and causing damage. Then, after the position adjustment of the second nasal oxygen tube 4 and the first nasal oxygen tube 8 is completed, pull the ends of the two first nasal oxygen tubes 8 at the same time and push the fastening block 1101 upward at the same time, and then fix the second nasal oxygen tube 4 to the patient tightly and then tie a knot at the ends of the two first nasal oxygen tubes 8, thereby limiting the downward movement of the fastening block 1101, thereby completing the fixation between the second nasal oxygen tube 4 and the patient.
