The patented technology includes a connecting plate with an air vent on the inner bottom wall and a silicone strip with a placement hole at one end. An air storage bag for storing gas is fixedly connected to one end of the connecting plate. A metal strip for shaping is inserted into the inner wall of the placement hole so that one end of the metal strip is inserted into the inner wall of the placement hole to fix the shape of the silicone strip. The medical oxygen supply tube for clinical use in internal medicine, through the combination of the air vent, the connecting plate and the air storage bag, when the patient or medical staff touches the storage box, the air storage bag can play a certain buffering role on the storage box, so as to prevent one end of the rubber plug from being inserted into the deep nasal cavity of the patient and poking the patient's nasal mucosa, so that the patient feels pain at the injured part of the nasal mucosa when breathing, and produces irritability to affect the patient's further acceptance of treatment, thereby effectively improving the practicality of the device.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing medical oxygen tubes are unable to store the oxygen tube body, resulting in a failure to obtain a good storage environment when the oxygen tube body needs to be recycled, and the existing medical oxygen tubes are unable to be limited and fixed during the use of the oxygen tubes, resulting in the oxygen tubes being affected by external forces and falling off during use, causing unnecessary harm to the patient.

As the circular block 8 moves outward, the circular block 8 is subjected to the tension and drives the surface of the plug rod 11 to gradually break away from the inner diameter of the plug hole 12. At this time, the rotating rod 3 will not be bound by the plug rod 11 and can rotate. As the staff turns the rotating handle 5, the surface of the rotating rod 3 rotates inside the box body 1, and the oxygen delivery tube body 15 is wound and tightened.

The surface of the rotating rod 3 is provided with a hole 12, and the inner diameter of the hole 12 is slidably connected to the surface of the plug rod 11. The staff pulls the pull tab 10 outward to make the surface of the circular block 8 slide outward on the inner cavity surface of the sleeve 6, and at the same time drives the surface of the plug rod 11 to gradually break away from the inner diameter of the hole 12. Through the arrangement of the plug rod 11, the hole 12 and other structures, it is convenient for the staff to fix and limit the rotating rod 3. The surface of the rear end of the limiting shell 2 is fixedly connected with a tension spring 13, and the rear end of the tension spring 13 is connected to the The surface of the front end of the circular block 8 is fixedly connected, and the inner diameter of the tension spring 13 is slidably connected to the surface of the insertion rod 11. The staff pulls the pull tab 10 outward, so that the circular block 8 drives the tension spring 13 to move outward and stretch and store force at the same time. When the staff needs to make the surface of the insertion rod 11 continue to be inserted into the inner diameter of the hole 12, the staff releases the tension on the pull tab 10, so that the tension spring 13 releases the stored force and pulls the surface of the circular block 8 to slide inward on the inner cavity surface of the sleeve 6, while driving the surface of the insertion rod 11 to continue to be inserted into the inner diameter of the hole 12. Through the setting of the tension spring 13, the surface of the insertion rod 11 can be continuously inserted into the inner diameter of the hole 12, preventing the insertion rod 11 from being disengaged due to external force The inner diameter of the socket 12 affects the limiting of the rotating rod 3. The surface of the rotating rod 3 is fixedly connected with a fixed disc 14. There are two fixed discs 14 and they are evenly distributed on the surface of the rotating rod 3. The surface of the rotating rod 3 is wrapped with an oxygen supply tube body 15. The surface of the oxygen supply tube body 15 is slidably connected to the interior of the front end of the box body 1. The staff rotates the rotating handle 5 to make the rotating handle 5 drive the surface of the rotating rod 3 to rotate inside the box body 1, so that the oxygen supply tube body 15 is wrapped around the surface of the rotating rod 3. Through the arrangement of the fixed disc 14 and the oxygen supply tube body 15, it is convenient for the staff to collect and fix the oxygen supply tube body 15, which is convenient for the staff to use next time and reduces the labor of the staff.

The setting of the return spring 25 makes it easy for the staff to limit and fix the nasal tube 19.

[0028] According to the working principle of the utility model, when the staff needs to recover and fix the oxygen delivery tube body 15, the staff pulls the pull tab 10 outward, so that the pull tab 10 drives the rotating block 9 to move outward, and at the same time drives the surface of the circular block 8 to slide outward on the inner cavity surface of the opening groove 7. As the circular block 8 moves outward, the circular block 8 is subjected to the tension and drives the surface of the plug rod 11 to gradually break away from the inner diameter of the plug hole 12. At this time, the rotating rod 3 will not be bound by the plug rod 11 and can rotate. As the staff turns the rotating handle 5, the surface of the rotating rod 3 rotates inside the box body 1, and the oxygen delivery tube body 15 is wound and tightened.
