Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of negative pressure drainage, in particular to an anti-clogging drainage tube. Background Art
[0002] Negative pressure drainage technology is now relatively common. It can drain wounds, remove excess exudate, and provide a relatively moist environment for damaged tissue healing. It can also reduce periwound edema, stimulate granulation tissue proliferation, and accelerate the healing process. However, due to the patient's position, the drainage tube can sometimes bend or flatten during exudate drainage, leading to blockage and rendering negative pressure therapy ineffective. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an anti-clogging drainage tube which can prevent pipeline blockage and maintain effective negative pressure treatment.
[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0005] The invention discloses an anti-blocking drainage tube, comprising a tube body. The tube body is provided with an anti-blocking portion formed on its wall along a circumferential direction for always keeping the inner cavity of the tube body unobstructed when the tube body is squeezed or folded.
[0006] As a further improvement of the above technical solution:
[0007] The anti-blocking parts are formed on the inner side wall of the tube wall, and the anti-blocking parts are arranged at intervals along the circumferential direction of the inner side wall.
[0008] The anti-blocking part includes anti-extrusion teeth and anti-folding teeth. The outer contours of the anti-extrusion teeth and the anti-folding teeth are set to conical surfaces. The anti-extrusion teeth are arranged at intervals along the circumferential direction of the inner wall of the tube wall and cover the entire inner wall. The anti-extrusion teeth conflict with each other when the tube body is squeezed or folded.
[0009] The anti-extrusion teeth are arranged at intervals along the length direction of the tube wall.
[0010] Each of the anti-folding teeth is arranged between each of the anti-extrusion teeth, and the tooth wall of the anti-folding tooth abuts against the tooth walls of two adjacent anti-extrusion teeth.
[0011] The anti-folding teeth cover at least half of the inner wall of the tube.
[0012] The anti-folding teeth are arranged along the length direction of the tube wall.
[0013] The anti-blocking portion includes two first anti-blocking platforms and two second anti-blocking platforms, which are staggered in the circumferential direction of the inner wall of the tube wall. The first anti-blocking platforms and the second anti-blocking platforms conflict with each other when the tube body is squeezed or folded.
[0014] The first anti-blocking platform comprises convex teeth and abutting seats formed at the bottom of the convex teeth and extending to both sides, the convex teeth abutting against the second blocking platform on both sides when the pipe body is extruded or folded, and the abutting seats abutting against the bottom of the second anti-blocking platform on both sides.
[0015] The second anti-blocking platform comprises two protrusions and a groove formed between the two protrusions, and the protrusions abutting against the convex teeth when the pipe body is extruded or folded.
[0016] The protrusions and the corresponding convex teeth form a groove.
[0017] The anti-blocking part is formed on the outer wall of the pipe wall, and the anti-blocking part extends along the circumferential direction of the outer wall to form a surrounding support for the pipe body.
[0018] The anti-blocking part comprises a plurality of anti-blocking rings, and each anti-blocking ring is arranged at intervals along the length direction of the pipe wall.
[0019] One end of each anti-blocking ring is connected to the outer wall of the pipe wall, and the other end is suspended on the next anti-blocking ring.
[0020] Compared with the prior art, the anti-blocking drainage tube has the following advantages:
[0021] The first embodiment of the anti-blocking drainage tube comprises a pipe body, and an anti-blocking part is formed on the pipe wall of the pipe body along the circumferential direction, which keeps the inner cavity of the pipe body unblocked when the pipe body is extruded or folded. By arranging the anti-blocking part on the pipe wall, the anti-blocking part is stressed when the pipe body is extruded or folded, thereby keeping the inner cavity of the pipe body unblocked. The deformation of the pipe body caused by extrusion or folding is prevented, and the effectiveness of negative pressure treatment is ensured. BRIEF DESCRIPTION OF DRAWINGS

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Example 1:
[0029] like Figure 1 As shown, the first embodiment of the anti-clogging drainage tube of the present invention comprises a tube body 1 having an anti-clogging portion 2 formed circumferentially on its wall 11 to maintain the lumen of the tube body 1 unobstructed when the tube body 1 is squeezed or folded. By providing the anti-clogging portion 2 on the wall 11, the anti-clogging portion 2 is subjected to force when the tube body 1 is squeezed or folded, maintaining the lumen of the tube body 1 unobstructed. This prevents deformation of the tube body 1 from causing blockage when squeezed or folded, thereby ensuring the effectiveness of negative pressure therapy.
[0030] In this embodiment, the anti-clogging portions 2 are formed on the inner sidewall of the tube wall 11 and are spaced apart along the circumference of the inner sidewall. In this structure, the anti-clogging portions 2 are provided on the inner sidewall of the tube wall 11 and are concealed therein, thereby increasing the service life and maintaining a smooth exterior of the tube body 1.
[0031] In this embodiment, the anti-blocking portion 2 includes anti-extrusion teeth 21 and anti-folding teeth 22. The outer contours of the anti-extrusion teeth 21 and the anti-folding teeth 22 are configured as conical surfaces. The anti-extrusion teeth 21 are spaced apart along the circumferential direction of the inner sidewall of the tube wall 11 and cover the entire inner sidewall. The anti-extrusion teeth 21 will interfere with each other when the tube body 1 is squeezed or folded. In this structure, the anti-extrusion teeth 21 are spaced apart along the circumferential direction of the inner sidewall. Regardless of the direction of the squeezing force or folding force applied to the tube body 1, the anti-extrusion teeth 21 at the corresponding position will interfere with the corresponding anti-extrusion teeth 21, preventing further deformation of the tube body 1 and avoiding blockage of the pipeline.
[0032] In this embodiment, the anti-extrusion teeth 21 are arranged at intervals along the length direction of the tube wall 11. In this structure, the anti-extrusion teeth 21 are arranged in this way so that the tube body 1 retains the basic bending function.
[0033] In this embodiment, each anti-folding tooth 22 is arranged between each anti-extrusion tooth 21, and the tooth wall of the anti-folding tooth 22 abuts against the tooth wall of the two adjacent anti-extrusion teeth 21. In this structure, the anti-folding teeth 22 are arranged in such a way that they abut against the anti-extrusion teeth 21, thereby increasing the folding stress and preventing the pipe body 1 from being folded by external force and causing pipe blockage.
[0034] In this embodiment, the anti-folding teeth 22 cover at least half of the inner wall of the tube wall 11. In this structure, the anti-folding teeth 22 are arranged so that the tube body 1 cannot be folded in half at any position, and the space occupied by the inner cavity of the tube body 1 can be reduced, thereby increasing the drainage path.
[0035] In this embodiment, the anti-folding teeth 22 are arranged along the length direction of the tube wall 11. Such an arrangement prevents the tube body 1 from being folded along its entire length.
[0036] Example 2:
[0037] like Figure 2 As shown, the second embodiment of the anti-clogging drainage tube of the present invention is basically the same as the first embodiment, with the only difference being:
[0038] In this embodiment, the anti-clogging portion 2 includes two first anti-clogging lands 23 and two second anti-clogging lands 24. These lands are arranged alternately along the circumference of the inner sidewall of the tube wall 11. These lands 23 and 24 abut against each other when the tube body 1 is squeezed or folded. This structure prevents deformation of the tube body 1 from causing blockage when squeezed or folded, due to the force exerted by the first and second anti-clogging lands 23 and 24.
[0039] In this embodiment, the first anti-blocking platform 23 includes a convex tooth 231 and an abutment seat 232 formed at the bottom of the convex tooth 231 and extending to both sides. When the tube body 1 is squeezed or folded, the convex tooth 231 contacts the second blocking platform 24 on both sides, and the abutment seat 232 contacts the bottom of the second anti-blocking platform 24 on both sides. In this structure, the contact between the convex tooth 231 and the second anti-blocking platform 24 prevents the tube body 1 from being flattened or folded. The structure is simple, and the provision of the abutment seat 232 contacting the bottom of the second anti-blocking platform 24 increases the wall thickness of the tube wall 11, thereby enhancing the stress resistance of the tube body 1.
[0040] In this embodiment, the second anti-clogging platform 24 includes two protrusions 241 and a groove 242 formed between the two protrusions 241. The protrusions 241 contact the convex teeth 231 when the tube body 1 is squeezed or folded. The groove 242 ensures that the lumen of the tube body 1 remains unobstructed when the tube body 1 is squeezed or folded by external forces. The point contact between the protrusions 241 and the convex teeth 231 provides support, thereby improving the patency of the lumen of the tube body 1.
[0041] In this embodiment, a groove is formed between the protrusion 241 and the corresponding convex tooth 231. Such an arrangement further improves the patency of the inner cavity of the tube body 1.
[0042] Example 3:
[0043] like Figure 3 As shown, the third embodiment of the anti-clogging drainage tube of the present invention is basically the same as the first embodiment, with the only difference being:
[0044] In the embodiment, the anti-blocking part 2 is formed on the outer side wall of the pipe wall 11, and extends along the circumferential direction of the outer side wall to form a wrapping support for the pipe body 1. In the structure, the anti-blocking part 2 is arranged on the outer side wall, which is easy to process and form. The anti-blocking part 2 forms a wrapping for the pipe body 1, and forms a support when the pipe body 1 is extruded or folded, so as to avoid the pipe body 1 being flattened or folded, and prevent the pipeline from being blocked.
[0045] In the embodiment, the anti-blocking part 2 comprises a plurality of anti-blocking rings 25, and each anti-blocking ring 25 is arranged at intervals along the length direction of the pipe wall 11. In the structure, the anti-blocking rings 25 are arranged at intervals, so that the pipe body 1 retains a basic bending ability.
[0046] In the embodiment, one end of each anti-blocking ring 25 is connected to the outer side wall of the pipe wall 11, and the other end is suspended on the next anti-blocking ring 25. In the structure, when the external force on the anti-blocking ring 25 is too large, the suspended end of the anti-blocking ring 25 will be lapped on the next anti-blocking ring 25 to bear force together, so as to improve the stress capacity.
[0047] Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any skilled person in the art can make many possible changes and modifications to the technical solution of the utility model, or modify equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of the utility model, by using the disclosed technical contents. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, which does not depart from the content of the technical solution of the utility model, shall fall within the scope of protection of the technical solution of the utility model.
