Embodiment 1

[0040] like Figure 1-Figure 9 As shown, an anti-pull device for a medical drainage tube includes an anti-pull mechanism and a fixing belt 1 whose width can be folded and adjusted. The folded fixing belt 1 is fixed by double-sided adhesive or clips, and the anti-pull mechanism includes a sleeve The tapered snap ring 2 on the drainage tube 5 and the tapered snap ring 3 arranged on the fixing belt 1; the tapered snap ring 2 and the tapered snap ring 3 are both made of hard and elastic plastic materials, and the tapered snap ring 2 and the tapered snap ring 3 The ferrule 3 is provided with a through hole, the through hole penetrates 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 smaller than the outer diameter of the drainage tube 5, and the conical The ferrule 3 is provided with a linear fracture, which penetrates the side wall of the through hole along the axial direction of the ...

Embodiment 2

[0049] like image 3 As shown, on the basis of Embodiment 1, the inner side of the annular ring 21 is provided with an elastic buffer sheet 26 in this embodiment. The elastic buffer sheet 26 is made of a rubber material.

[0050] The provision of the elastic buffer sheet 26 can reduce the clamping deformation of the annular ring 21 to the drainage tube 5 , and also increase the frictional force between the annular ring 21 and the drainage tube 5 .

[0051] The remaining structures and working principles of Embodiment 2 are the same as those of Embodiment 1.

Embodiment 3

[0053] like Image 6 As shown, in this embodiment, on the basis of Embodiment 1, the anti-pulling mechanism further includes a pusher 6, which is arranged on the drainage tube 5 at a position close to the conical snap ring 2, and the pusher 6 is located on the edge of the annular ring 21. The side on which the spring clip 22 is provided. The pushing member 6 is an adhesive tape ring wound on the drainage tube 5 or a metal wire screwed on the drainage tube 5, and the adhesive tape ring is selected in this embodiment.

[0054] The pusher 6 increases the pushing force of the drainage tube 5 to the conical snap ring 2 to prevent the conical snap ring 2 from slipping due to various reasons, so that the purpose of the conical snap ring 2 being squeezed on the conical snap ring 3 cannot be achieved .

[0055] The rest of the structure and the working principle of Embodiment 3 are the same as those of Embodiment 1.

Abstract

The invention belongs to the technical field of medical devices, solves the technical problem in the prior art that the drainage tube is easily pulled and causes unplanned extubation, and provides a medical drainage tube anti-pulling device, comprising an anti-pull mechanism and a fixing belt, The width of the fixing belt is adjustable, and the anti-pulling mechanism includes a conical snap ring sleeved on the drainage tube and a conical ferrule set on the fixing belt; a through hole is provided on the tapered ferrule The through-hole passes through the conical ferrule along the axial direction of the conical ferrule, the through-hole is conical, and the diameter of the through-hole is not smaller than the outer diameter of the drainage tube; An opening is provided, the opening penetrates the side wall of the through hole along the axial direction of the tapered ferrule, and the opening is arranged away from the fixing band. Connection mechanism at the opening. The medical drainage tube anti-pulling device of the present invention has the advantages of preventing the drainage tube from being moved by external force, and being suitable for various types of drainage tubes.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical drainage tube anti-pull device. Background technique [0002] Surgical drainage is to guide pus, blood, and fluid accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection and affect wound healing. As a surgical drainage device, drainage tubes are widely used in catheterization, wounds, chest cavity, brain cavity, gastrointestinal tract, biliary tract drainage, etc. In daily use, the drainage tube is easy to be pulled, resulting in unplanned extubation. If the fixation of the drainage tube and the anti-pull measures are not set properly, once the wound is pulled out by external force, the wound will be infected in mild cases, and the patient's life will be endangered in severe cases. Common drainage tube fixing devices cannot be used for most drainage tubes. SUMMARY OF THE INVENTION [0003] The embodime...
