Embodiment 1
[0040] Such as Figure 1-Figure 9 As shown, a medical drainage tube anti-pull device includes an anti-pull mechanism and a fixed belt 1 with a foldable and adjustable width. The folded fixed belt 1 is fixed by double-sided adhesive or clips. The anti-pull mechanism includes a socket The tapered snap ring 2 on the drainage tube 5 and the tapered ferrule 3 arranged on the fixing band 1; the tapered snap ring 2 and the tapered ferrule 3 are all made of hard plastic material with elasticity. A through hole is provided on the ferrule 3, and the through hole penetrates through the conical ferrule 3 along the axial direction of the conical ferrule 3. The through hole is conical, and the diameter of the through hole is not less than the outer diameter of the drainage tube 5. The ferrule 3 is provided with a straight line fracture, the straight line fracture runs through the side wall of the through hole along the axial direction of the tapered ferrule 3, and the straight line fracture...
Embodiment 2
[0049] Such as image 3 As shown, this embodiment is based on the first embodiment, and the inner surface of the annular ring 21 is provided with an elastic buffer piece 26 . The elastic buffer sheet 26 is made of rubber material.
[0050] The arrangement of the elastic buffer sheet 26 can reduce the clamping deformation of the annular ring 21 on the drainage tube 5 and also increase the friction between the annular ring 21 and the drainage tube 5 .
[0051] The rest of the structure and working principle of embodiment 2 are the same as embodiment 1.
Embodiment 3
[0053] Such as Figure 6 As shown, in this embodiment, on the basis of Embodiment 1, the anti-pull mechanism also includes a pusher 6, which is arranged on the drainage tube 5 close to the tapered snap ring 2, and the pusher 6 is located at the end of the annular ring 21. One side of the elastic clip 22 is set. The pusher 6 is an adhesive tape loop wound on the drainage tube 5 or a wire screwed on the drainage tube 5, and the adhesive tape loop is selected in this embodiment.
[0054] The pusher 6 increases the driving force of the drainage tube 5 on the tapered snap ring 2 to prevent the tapered snap ring 2 from slipping due to various reasons, so that the purpose of the tapered snap ring 2 being squeezed on the tapered ferrule 3 cannot be realized .
[0055] The rest of the structure and working principle of Embodiment 3 are the same as Embodiment 1.
