[0023] Please see Figure 1-4 This utility model provides an embodiment of a nasogastric tube fixing device to prevent detachment, comprising a tube clamp 1, a tube body 2 movably disposed inside the tube clamp 1, a connecting strap 7 fixed to the top of the tube clamp 1, a connecting block 11 fixed to the front end of the connecting strap 7, a first elastic band 5 fixed to the right side of the connecting block 11, and a fixing buckle 6 fixed to one end of the first elastic band 5, a second elastic band 9 fixed to the left side of the connecting block 11, and a hole 10 disposed inside the second elastic band 9, and a fixing buckle 6 disposed at the rear end of the connecting strap 7. The adhesive tape 12 has a release film 13 at its rear end. Several holes 10 are provided, and the holes 10 are evenly distributed inside the second elastic bandage 9. The evenly distributed holes 10 make it easy to tie the first elastic bandage 5 and the second elastic bandage 9 to the head of patients of different sizes. The size of the release film 13 is equal to the size of the adhesive tape 12. The release film 13 and the adhesive tape 12 are compatible and provide comprehensive dust protection for the adhesive tape 12 when it is not in use.
[0024] Specifically, such as Figure 1 and Figure 3 As shown, after the adhesive tape 12 is attached to the patient's face, the first elastic band 5 and the second elastic band 9 are pulled to wrap around from one side of the patient's head to the back of the head. Then, the fixing buckle 6 inside the first elastic band 5 is fastened to the hole 10 at a suitable position on one end of the surface of the second elastic band 9, so that the first elastic band 5 and the second elastic band 9 bind the adhesive tape 12, increasing its stability on the patient's face.
[0025] The front end of the fixing tape 12 is fixed with a buckle body 8, and the top of the inside of the connecting strap 7 is provided with a connecting hole 17. The buckle body 8 and the connecting hole 17 are matched and form a snap-fit structure, which makes it convenient to replace the fixing tape 12 and reuse the fixing device.
[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, after the adhesive tape 12 is removed from the patient's face after one use, the buckle 8 can be pried off to separate it from the connecting hole 17 inside the connecting strap 7. Then, a new adhesive tape 12 can be taken and its top buckle 8 can be fastened together with the connecting hole 17 inside the connecting strap 7, thereby installing the new adhesive tape 12 for use.
[0027] A threaded rod 14 is movably provided on the right side inside the pipe clamp 1, and a rotating block 4 is installed on one side of the threaded rod 14. A clamping block 3 is movably provided on the other side of the threaded rod 14. A guide groove 15 is provided at the front end of the clamping block 3. A guide block 16 is movably provided inside the guide groove 15, and one end of the guide block 16 is fixed to one end of the clamping block 3. The cross-section of the guide groove 15 is larger than the cross-section of the guide block 16. A sliding structure is formed between the guide groove 15 and the guide block 16. An internal thread is movably provided on one side inside the pipe clamp 1. A threaded connection is formed between the pipe clamp 1 and the threaded rod 14. The clamping block 3 is pushed to move stably to one side to clamp the pipe body 2.
[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, after the pipe body 2 is inserted into the pipe clamp 1, the rotating block 4 causes the threaded rod 14 to rotate. Through the sliding of the guide block 16 inside the guide groove 15, the clamping block 3 moves to one side and fits against the outer wall of the pipe body 2 to lock the pipe body 2, so that the pipe body 2 is installed inside the pipe clamp 1.
[0029] Working principle: When using this utility model, the end of the tube 2 is inserted into the corresponding position inside the patient's nasal cavity. Then, the fixing device is removed, and the tube 2 is clamped into the tube clamp 1. The rotating block 4 is rotated so that the threaded rod 14 rotates and pushes the clamping block 3 to one side to fit against the outer wall of the tube 2 through the sliding of the guide block 16 in the guide groove 15, thus locking the tube 2. After the tube 2 is installed inside the tube clamp 1, the release film 13 is peeled off to open the fixing tape 12 and stick it to the patient's face to limit and fix the tube 2. After fixing, the first elastic band 5 and the second elastic band 9 are pulled so that they are wrapped around the back of the patient's head from one side. Then, the fixing buckle 6 inside the first elastic band 5 is fastened to the hole 10 at a suitable position on one end of the second elastic band 9, so that the first elastic band 5 and the second elastic band 9 limit and reinforce the fixing tape 12, making the fixing device more stable in fixing the nasogastric tube.
