Detailed Implementation

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] See attached document Figure 1 -Appendix Figure 5 This utility model provides a drainage tube anti-pulling device, including

[0032] Mounting ring 1, which is a semi-open structure, and multiple mounting bolts 16 are embedded inside the mounting ring 1;

[0033] A fixing block 2 is fixedly connected to the front side of the mounting ring 1, and a positioning frame 3 is fixedly connected to the front side of the fixing block 2.

[0034] The drainage tube body 4 is located inside the positioning frame 3;

[0035] A buffer mechanism is located inside the positioning frame 3;

[0036] The buffer mechanism includes a wrapping tube 5, which is sleeved on the outside of the drainage tube body 4. Multiple pull ropes 6 are provided inside the wrapping tube 5. All pull ropes 6 are sleeved on the outside of the drainage tube body 4. The outer ends of the multiple pull ropes 6 extend to the outside of the wrapping tube 5. The inner ends of the multiple pull ropes 6 are fixedly connected to limit rings 20.

[0037] In this embodiment, the user passes the drainage tube body 4 through the wrapping tube 5, so that multiple pull ropes 6 are wrapped around the outside of the drainage tube body 4. When the medical staff accidentally pulls the drainage tube, the buffer mechanism pulls the drainage tube in the opposite direction to prevent the drainage tube from being stretched.

[0038] To achieve the purpose of buffering, the device adopts the following technical solution: The buffering mechanism also includes a movable plate 7, which is located inside the positioning frame 3. The movable plate 7 is fixedly connected to the outer ends of multiple pull ropes 6. A movable groove is opened on the rear side of the movable plate 7, and two movable blocks 8 are embedded in the movable groove. Both movable blocks 8 slide with the movable plate 7. A movable rod 9 is provided on the rear side of each of the two movable blocks 8. The two movable rods 9 are respectively connected to the two movable blocks 8 through hinges. The rear ends of the two movable rods 9 are connected to the inner side of the positioning frame 3. The movable rods 9 and the positioning frame 3 are connected through hinges. A positioning block 10 is fixedly connected to the inner side of each of the two movable rods 9. A first spring 11 is fixedly connected between the two positioning blocks 10. Horizontal plates 12 are fixedly connected to the front and rear sides of the wrapping tube 5. The two horizontal plates 12 are respectively attached to the inner walls of the front and rear sides of the positioning frame 3. A second spring 13 is fixedly connected to one side of the rear side of each of the two horizontal plates 12. The two second springs 13 are fixedly connected to the positioning frame 3.

[0039] When the drainage tube body 4 is pulled, the wrapping tube 5 moves outward. The movement of the wrapping tube 5 drives the horizontal plate 12 to move, which stretches the second spring 13. The elastic force of the second spring 13 exerts a reaction force on the wrapping tube 5. At the same time, the movement of the wrapping tube 5 also stretches multiple pull ropes 6. The stretching of the pull ropes 6 drives the movable plate 7 to move. The movement of the movable plate 7 drives the two movable rods 9 to rotate, which reduces the angle between the two movable rods 9. At this time, the two movable rods 9 squeeze the first spring 11, causing the first spring 11 to compress, thus achieving a better buffering effect. At this time, the tightening of the pull ropes 6 will stretch the drainage tube in the opposite direction, achieving an anti-stretching effect.

[0040] In order to achieve the purpose of limiting, the device adopts the following technical solution: the top of the two horizontal plates 12 are fixedly connected to the limiting blocks 14, the two limiting blocks 14 are embedded with the limiting rods 15, and one end of the two limiting rods 15 is fixedly connected to the inside of the positioning frame 3.

[0041] The design of the limiting block 14 and the limiting rod 15 allows the wrapping tube 5 to move stably left and right;

[0042] In order to achieve the purpose of limiting, the device adopts the following technical solution: the positioning frame 3 has a moving groove on both the front and rear sides, the two horizontal plates 12 are provided with round rods 17 on the outside, the two round rods 17 extend to the outside of the two moving grooves respectively, the outer ends of the two round rods 17 are fixedly sleeved with stop bars 18, and the positioning frame 3 has multiple alarm bells 19 on both the front and rear sides.

[0043] When the two guide tube bodies 4 are pulled, the horizontal plate 12 moves, which drives the round rod 17 and the stop bar 18 to move, thereby striking multiple alarm bells 19, causing multiple alarm bells 19 to sound and achieve the effect of alarm.

[0044] The usage process of this utility model is as follows: The user passes the drainage tube body 4 through the wrapping tube 5, causing multiple pull ropes 6 to wrap around the outside of the drainage tube body 4. When medical personnel accidentally pull the drainage tube, the buffer mechanism pulls back on the drainage tube to prevent stretching. When the drainage tube body 4 is pulled, the wrapping tube 5 moves outward, causing the horizontal plate 12 to move, thus stretching the second spring 13. The elastic force of the second spring 13 exerts a reaction force on the wrapping tube 5. Simultaneously, the movement of the wrapping tube 5 also stretches the multiple pull ropes 6, causing the movable plate 7 to move. The movement drives the two movable rods 9 to rotate, thereby reducing the angle between the two movable rods 9. At this time, the two movable rods 9 squeeze the first spring 11, causing the first spring 11 to compress, thus achieving a better buffering effect. At this time, the tightening of the pull rope 6 will stretch the drainage tube in the opposite direction, achieving an anti-stretching effect. The design of the limiting block 14 and the limiting rod 15 allows the wrapping tube 5 to move stably left and right. When the two drainage tube bodies 4 are pulled, the movement of the horizontal plate 12 will drive the round rod 17 and the stop rod 18 to move, thereby striking multiple alarm bells 19, causing multiple alarm bells 19 to sound and achieve an alarm effect.

[0045] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
