[0026] Referring to Figures 1-5 as shown, the present utility model provides a technical solution: a rotary high-flow nasal oxygen tube, including a catheter body 12.
[0027] The following specifically describes its overall specific settings and functions.
[0028] In this implementation: One end of the side wall of the catheter body 12 is connected to a sleeve 5, the other end of the catheter body 12 is connected to a second rotary joint 11, the other end of the sleeve 5 is connected to a catheter connector 2, the other end of the catheter connector 2 is connected to a first rotary joint 1, a nasal cannula bracket 10 is fixedly installed at the port of the second rotary joint 11, a nasal cannula body 8 is fixedly installed on the side of the nasal cannula bracket 10, two silicone nasal plugs 14 are communicated with the surface of the nasal cannula body 8, two elastic band buckles 9 are detachably installed on the surface of the nasal cannula body 8, an elastic band 7 is detachably installed between the two elastic band buckles 9, a hose clamp 6 is sleeved on the side wall of the catheter body 12, a white rope 3 is installed on the side wall of the catheter structure, an alligator clip 4 is sleeved on the outside of the white rope 3, a hanging rope 13 is installed on the side wall of the catheter connector 2, and a plastic film 15 is sleeved on the surface of the silicone nasal plug 14. The comfortable and well-tolerated silicone nasal plugs 14 contribute to patient compliance; the setting of the first rotary structure and the second rotary joint 11 facilitates connection and disconnection; the wide elastic and detachable elastic band 7 is easy to adjust and provides a firm fit, increasing the comfort of the patient; the adjustable hose clamp 6 can reduce resistance and, in cooperation with the hanging rope 13 and the alligator clip 4, provides additional support. Before using the high-flow nasal oxygen tube, putting the plastic film 15 on the surface of the silicone nasal plug 14 can cover the end position of the silicone nasal plug 14.
[0029] Specifically, a ventilation net 16 is fixedly installed at the upper port of the plastic film 15. By setting the ventilation net 16, it is convenient to block nasal mucus without affecting ventilation. A reserved groove 17 is opened on the outside of the silicone nasal plug 14, and a folding sleeve 18 is slidably sleeved on the inner wall of the reserved groove 17. The folding sleeve 18 is a telescopic structure, and the folding sleeve 18 is fixedly connected to the bottom wall of the reserved groove 17. The setting of the folding sleeve 18 facilitates the pressing and fixing of the plastic film 15. A support ring 19 is fixedly installed at the upper port of the folding sleeve 18. The support ring 19 will be pressed against the inside of the reserved groove 17 under the elastic force of the folding sleeve 18, so as to fix the plastic film 15. A plurality of convex strips 20 are fixedly connected to the upper end of the support ring 19, and the cross section of the convex strip 20 is a triangular structure. By setting the convex strips 20, the friction force for pressing the port position of the plastic film 15 is increased, thereby improving the stability of pressing the port position of the plastic film 15. A plurality of air holes 21 are evenly opened on the surface of the support ring 19. The setting of the air holes 21 facilitates the discharge of the air inside the folding sleeve 18 during the compression of the folding sleeve 18, reducing the resistance to pressing the folding sleeve 18.
[0030] The working principle is that the comfortable and well-tolerated silicone nasal plug 14 helps with patient compliance; the setting of the first rotating structure and the second rotating joint 11 facilitates connection and disconnection; the wide elastic and detachable elastic band 7 is easy to adjust and provides a firm fit, increasing the patient's comfort; the adjustable tube clamp 6 can reduce resistance and, when used in conjunction with the lanyard 13 and the alligator clip 4, provides additional support. Before using the high-flow nasal oxygen tube, putting the plastic film 15 on the surface of the silicone nasal plug 14 can cover the end position of the silicone nasal plug 14. By setting the breathable net 16, it is convenient to block nasal mucus without affecting ventilation, avoiding the blockage of the silicone nasal plug 14. After putting the plastic film 15 on the surface of the silicone nasal plug 14, tuck the plastic at the side position of the end of the silicone nasal plug 14 between the inside of the support ring 19 and the reserved groove 17. The support ring 19 will be pressed against the inside of the reserved groove 17 under the elastic force of the folding sleeve 18, thereby realizing the fixation of the plastic film 15. By setting the convex strip 20, the friction for pressing the port position of the plastic film 15 is increased, thus improving the stability of pressing the port position of the plastic film 15. The setting of the air hole 21 facilitates the discharge of the air inside the folding sleeve 18 during the compression of the folding sleeve 18, reducing the resistance to pressing the folding sleeve 18. When the plastic film 15 needs to be replaced, the staff only needs to compress the folding sleeve 18 to loosen the lower port position of the plastic film 15, facilitating the replacement of the plastic film 15. By setting the above structures, it is convenient to regularly replace the plastic film 15 on the silicone nasal plug 14, convenient for protecting the silicone nasal plug 14, and reducing the situation of the silicone nasal plug 14 being stained, improving the usage effect of the silicone nasal plug 14.
