Two symmetrically distributed limit top protrusions 41 are integrally formed at the top of the inner wall of the fixing frame 2. A through slot 201 is formed in the fixing frame 2 between the two limit top protrusions 41. The size of the through slot 201 is larger than the size of the limit bottom protrusion 4, facilitating the limit bottom protrusion 4 on the bottom cover 3 to pass through the through slot 201 and be placed below the two limit top protrusions 41, in the middle of the fixing frame 2; the inner diameter size of the fixing frame 2 is larger than the outer diameter size of the bottom cover 3; the bottom cover 3 is movably clamped in the fixing frame 2, and the limit bottom protrusion 4 is movably clamped in the middle of the inner side of the fixing frame 2. The upper surface of the limit bottom protrusion 4 contacts the lower surface of the limit top protrusion 41. The limit bottom protrusion 4 is limited by the limit top protrusion 41, so that the bottom cover 3 is limited by the fixing frame 2, and further the bottom of the tee pipe body 1 is limited and fixed by the fixing frame 2, improving the stability of the tee pipe body 1;

[0021] A limit rubber ring 5 is fixedly clamped at the bottom of the inner wall of the fixing frame 2. A plurality of friction protrusions 51 are integrally formed on the inner side of the limit rubber ring 5. The bottom of the bottom cover 3 is movably clamped in the limit rubber ring 5. The outer wall of the bottom cover 3 contacts the friction protrusions 51. When the limit top protrusion 41 limits the limit bottom protrusion 4, the bottom of the bottom cover 3 is movably clamped in the limit rubber ring 5. The outer wall of the bottom cover 3 contacts the friction protrusions 51. The outer wall of the bottom cover 3 is frictionally engaged by the friction protrusions 51 to reduce the self-rotation of the bottom cover 3;

[0022] At the bottom of the outer wall of the fixed frame 2, a first connecting band 6 is fixedly connected. On one side of the bottom of the outer wall of the fixed frame 2 away from the first connecting band 6, a second connecting band 61 is fixedly connected. On the lower surface of the end of the first connecting band 6 away from the fixed frame 2, a magic mother sticker 7 is fixedly connected. On the upper surface of the end of the second connecting band 61 away from the fixed frame 2, a magic son sticker 71 that is used in cooperation with the magic mother sticker 7 is fixedly connected; the magic mother sticker 7 and the magic son sticker 71 can be adhesively connected to each other. By providing the first connecting band 6 and the second connecting band 61 and using the magic mother sticker 7 and the magic son sticker 71 in cooperation, when in use, the fixed frame 2 is placed on the patient's arm, the first connecting band 6 and the second connecting band 61 are wound around the patient's arm, so that the magic mother sticker 7 and the magic son sticker 71 are adhesively connected to each other, and the fixed frame 2 and the patient's arm are fixed through the first connecting band 6 and the second connecting band 61, thereby fixing the tee tube body 1 on the patient's arm, preventing the tee tube body 1 from causing pressure sores to the patient, facilitating the reuse of finding the tee tube body 1 again, and preventing the tee tube body 1 from falling off.

[0023] A protective rubber ring 8 is provided on the lower surface of the fixed frame 2; the protective rubber ring 8 is made of medical-grade silicone material; a clamping ring 81 is integrally formed on the upper surface of the protective rubber ring 8, and a clamping groove 82 corresponding to the clamping ring 81 is formed on the lower surface of the fixed frame 2, and the clamping ring 81 is fixedly clamped in the clamping groove 82. When the fixed frame 2 is placed on the patient's arm, the protective rubber ring 8 made of medical-grade silicone material contacts the surface of the patient's arm, providing contact protection for the surface of the patient's arm and improving the comfort of the patient wearing the fixed frame 2.

[0024] Working principle: When in use, the fixed frame 2 is placed on the patient's arm, and the protective rubber ring 8 made of medical-grade silicone material contacts the surface of the patient's arm, providing contact protection for the surface of the patient's arm. Subsequently, the first connecting band 6 and the second connecting band 61 are wound around the patient's arm, so that the magic mother sticker 7 and the magic son sticker 71 are adhesively connected to each other, and the fixed frame 2 and the patient's arm are fixed through the first connecting band 6 and the second connecting band 61;

[0025] Subsequently, hold the tee tube body 1 with the bottom cover 3 and movably clamp the bottom cover 3 in the fixed frame 2. At this time, the limiting bottom convex 4 is placed below the two limiting top convexes 41 through the through groove 201 and is placed in the middle of the fixed frame 2. Manually rotate the tee tube body 1 and the bottom cover 3, and the limiting bottom convex 4 rotates in the middle of the inner side of the fixed frame 2, so that the upper surface of the limiting bottom convex 4 contacts the lower surface of the limiting top convex 41, and the limiting bottom convex 4 is limited by the limiting top convex 41, thereby limiting the bottom cover 3 through the fixed frame 2, and further limiting and fixing the bottom of the tee tube body 1 through the fixed frame 2, fixing the tee tube body 1 on the patient's arm, preventing the tee tube body 1 from causing pressure sores to the patient, facilitating the reuse of finding the tee tube body 1 again, and preventing the tee tube body 1 from falling off;

[0026] When the limiting top convex 41 limits the limiting bottom convex 4, the bottom of the bottom cover 3 is movably clamped in the limiting rubber ring 5, and the outer wall of the bottom cover 3 contacts the friction convex 51, and the outer wall of the bottom cover 3 is rubbed by the friction convex 51 to reduce the self-rotation of the bottom cover 3.
