Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of negative pressure drainage, in particular to a catheter for negative pressure drainage coupled with electric field treatment and flushing. Background Art
[0002] Negative pressure drainage technology is now relatively common. Negative pressure therapy can drain wounds, remove excess exudate, and provide a relatively moist environment for the healing of damaged tissues. It can also reduce periwound edema and stimulate granulation tissue proliferation, thereby accelerating the healing process. Furthermore, electric field stimulation can also have a rapid healing effect on wounds. However, when draining exudate through a catheter, the patient's position can sometimes cause the tubing to bend or flatten, leading to blockage and ineffective negative pressure therapy. Furthermore, electric field catheters are difficult to use in combination with negative pressure drainage and irrigation catheters. Excessive catheter lines can easily cross, leading to kinks and blockage of the negative pressure and irrigation lines. Utility Model Content

[0006] As a further improvement of the above technical solution:
[0007] Each of the reinforcing ribs divides the area between the inner tube and the outer tube into a plurality of channels, wherein some of the channels are configured as the flushing holes.

[0009] The anti-blocking portion further includes a plurality of anti-extrusion folding teeth whose number matches the flushing hole, and the anti-extrusion folding teeth are arranged at intervals along the circumferential direction of the inner wall of the drainage hole.
[0010] The outer contour of each of the anti-extrusion and folding teeth is set to be semicircular, and the anti-extrusion and folding teeth conflict with each other when the tube body is squeezed or folded.
[0011] Each of the anti-extrusion folding teeth is arranged below the corresponding flushing hole and forms a staggered arrangement with each of the anti-extrusion folding blocks.
[0012] Each of the anti-extrusion folding teeth is disposed below two corresponding adjacent reinforcing ribs and forms a continuous structure with each of the anti-extrusion folding blocks.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] like Figure 1 and Figure 2As shown, the catheter for negative pressure drainage coupled electric field therapy and flushing of this embodiment includes a tube body 1, which is provided with a flushing hole 2, a drainage hole 3 and an electric wire hole 4. The tube body 1 is formed with an anti-blocking portion 11 in the circumferential direction thereof for always keeping the inner cavities of the flushing hole 2 and the drainage hole 3 unobstructed when the tube body 1 is squeezed or folded. The tube body 1 includes an inner tube 12 and an outer tube 13. The anti-blocking portion 11 includes a plurality of reinforcing ribs 111, and each reinforcing rib 111 is arranged circumferentially along the outer wall of the inner tube 12 and the inner wall of the outer tube 13, and the inner tube 12 and the outer tube 13 are connected by each reinforcing rib 111. The flushing hole 2 is provided in the area between the inner tube 12 and the outer tube 13, and the inner cavity of the inner tube 12 is the drainage hole 3. The utility model forms a multifunctional catheter integrating negative pressure drainage, wound flushing and electric field stimulation therapy by arranging flushing holes 2, drainage holes 3 and electric wire holes 4 in the tube body 1, and by arranging reinforcing ribs 111 between the inner tube 12 and the outer tube 13, the ability of the tube body 1 to resist extrusion and folding is improved, avoiding the flushing holes 2 or the drainage holes 3 from bending or flattening when the tube body 1 is squeezed or folded, preventing pipeline blockage, and maintaining stable and effective negative pressure drainage therapy and flushing.
[0023] In this embodiment, each reinforcing rib 111 divides the area between the inner tube 12 and the outer tube 13 into a plurality of channels 14, wherein some of the channels 14 are configured as flushing holes 2. In this structure, the channels 14 separated by the reinforcing rib 111 are configured as flushing holes 2, which is simple in structure and easy to implement.
[0024] In this embodiment, the anti-blocking portion 11 further includes a plurality of anti-extrusion and folding blocks 112, each of which is arranged at intervals within the corresponding channel 14. A flushing hole 2 is provided between each two adjacent anti-extrusion and folding blocks 112, and the electrical wire hole 4 is provided on the anti-extrusion and folding block 112. In this structure, the anti-extrusion and folding blocks 112 are provided within the channel 14, further improving the anti-extrusion and folding ability of the tube body 1. Moreover, by arranging the anti-extrusion and folding blocks 112 at intervals, when the tube body 1 is squeezed, only the flushing holes 2 at the stress points are blocked, while the other flushing holes 2 remain unobstructed. In addition, the flushing holes 2 are evenly distributed within the tube body 1, ensuring uniform and sufficient flushing.
[0025] In this embodiment, the anti-clogging portion 11 further includes a plurality of anti-extrusion folding teeth 113, the number of which matches the number of flushing holes 2. The anti-extrusion folding teeth 113 are spaced apart along the circumferential direction of the inner wall of the drainage hole 3. In this structure, the anti-extrusion folding teeth 113 are supported by the force when the tube body 1 is squeezed or folded, thereby keeping the drainage hole 3 unobstructed.
[0026] In this embodiment, the outer contour of each anti-extrusion and folding tooth 113 is set to be semicircular, and each anti-extrusion and folding tooth 113 contacts each other when the tube body 1 is squeezed or folded. In this structure, the anti-extrusion and folding teeth 113 with a semicircular outer contour contact each other at a point. Through the contact of the anti-extrusion and folding teeth 113, the drainage hole 3 can always be kept unobstructed when the tube body 1 is squeezed or folded.
[0027] In this embodiment, each anti-extrusion folding tooth 113 is arranged below the corresponding flushing hole 2 and is staggered with each anti-extrusion folding block 112. In this structure, the staggered arrangement of the anti-extrusion folding teeth 113 and the anti-extrusion folding block 112 improves the overall rigidity of the tube body 1, making it less likely to fold in half.
[0028] In this embodiment, each anti-extrusion and folding tooth 113 is disposed beneath two adjacent reinforcing ribs 111 and forms a continuous structure with each anti-extrusion and folding block 112. In this structure, the anti-extrusion and folding teeth 113 provide reinforced support for the reinforcing ribs 111, improving the ability to resist extrusion and folding. Furthermore, the anti-extrusion and folding teeth 113 form a continuous structure with the anti-extrusion and folding blocks 112, increasing the torque of the tube body 1, preventing the tube body 1 from being vertically twisted by force, and avoiding pipeline blockage.
[0029] In this embodiment, each anti-extrusion and folding block 112 is arranged along the length direction of the tube body 1. In this structure, the anti-extrusion and folding block 112 is arranged along the length to ensure the overall anti-folding strength of the tube body 1.
[0030] In this embodiment, the anti-extrusion and folding teeth 113 are spaced apart along the length of the tube 1. In this structure, while ensuring the anti-extrusion and folding capability, the tube 1 has the ability to deform laterally, ensuring the ductility of the tube 1 and facilitating patient movement.

Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations.
