[0023] An anti-bending drain pipe includes: a lower fixing layer 1;

[0024] An anti-bending structure 2 is fixedly connected to the upper end of the lower fixing layer 1. A card slot 3 is opened at the upper end of the anti-bending structure 2. A drain pipe body 4 is clamped inside the card slot 3. A sleeve 5 is fixedly connected inside the anti-bending structure 2. A sliding rod 6 is slidably connected inside the sleeve 5. A limiting piece 7 is fixedly connected to the rear end of the sliding rod 6. A spring 8 is arranged inside the sleeve 5. The spring 8 is located between one side of the inner wall of the sleeve 5 and the limiting piece 7. A limiting block 9 for limiting the drain pipe body 4 is fixedly connected to the front end of the sliding rod 6. The arrangement of the limiting block 9 is beneficial to the drain pipe body 4 fitting inside the card slot 3.

[0025] A limiting groove 10 is opened at the upper end of the anti-bending structure 2. The limiting groove 10 communicates with the card slot 3.

[0026] A rubber pad 11 is fixedly connected to the inner wall of the limiting groove 10. A clamping block 12 is fixedly connected to the peripheral side surface of the drain pipe body 4. The arrangement of the rubber pad 11 is beneficial to clamping the clamping block 12 tightly.

[0027] Two groups of first magic tapes 13 are fixedly connected to the upper end of the lower fixing layer 1. The first magic tapes 13 are loop surfaces.

[0028] At the upper end of the lower fixing layer 1, there is an upper fixing layer 15. At the bottom of the upper fixing layer 15, there is a hook surface that matches the first magic tape 13 and the second magic tape 14. The setting of the upper fixing layer 15 is beneficial to protecting the drainage tube body 4. When the device is in use, a medical adhesive can be used to paste the lower fixing layer 1 on the skin.

[0029] The working principle of an anti-bending drainage tube provided by the present utility model is as follows:

[0030] First step: When in use, paste the lower fixing layer 1 on the human body, and insert the drainage tube body 4 into the inside of the card slot 3. The limiting block 9 presses the drainage tube body 4 against the inner wall of the card slot 3. When the outlet end of the drainage tube body 4 is pulled, the drainage tube body 4 will squeeze the limiting block 9. At this time, the limiting block 9 drives the sliding rod 6 to slide into the inside of the sleeve 5. At this time, the drainage tube body 4 can be loosened to resist the external pulling force. When the pulling of the drainage tube body 4 stops, the elastic force of the spring 8 makes the limiting block 9 reset. At this time, the drainage tube body 4 returns to the position where it fits with the card slot 3.

[0031] Second step: By inserting the clamping block 12 into the limiting slot 10, the clamping of the rubber pad 11 and the increased friction can prevent the clamping block 12 from falling off from the inside of the limiting slot 10. At this time, through the cooperation of the clamping block 12 and the limiting slot 10, one end of the drainage tube body 4 can be fixed, thereby preventing the inlet of the drainage tube body 4 from loosening.

[0032] Compared with the related technology, an anti-bending drainage tube provided by the present utility model has the following beneficial effects:

[0033] Paste the lower fixing layer 1 on the human body, insert the drainage tube body 4 into the inside of the card slot 3. The limiting block 9 presses the drainage tube body 4 against the inner wall of the card slot 3. When the outlet end of the drainage tube body 4 is pulled, the drainage tube body 4 will squeeze the limiting block 9. At this time, the limiting block 9 drives the sliding rod 6 to slide into the inside of the sleeve 5. At this time, the drainage tube body 4 can be loosened to resist the external pulling force. When the pulling of the drainage tube body 4 stops, the elastic force of the spring 8 makes the limiting block 9 reset. At this time, the drainage tube body 4 returns to the position where it fits with the card slot 3. Through this mechanism, the external pulling force can be resisted, the inlet of the drainage tube body 4 will not be loosened, and the normal drainage of the drainage tube body 4 will not be affected. By inserting the clamping block 12 into the limiting slot 10, the clamping of the rubber pad 11 and the increased friction can prevent the clamping block 12 from falling off from the inside of the limiting slot 10. At this time, through the cooperation of the clamping block 12 and the limiting slot 10, one end of the drainage tube body 4 can be fixed, thereby preventing the inlet of the drainage tube body 4 from loosening. Through this mechanism, the stability of the drainage tube body 4 can be further improved.

[0034] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
