[0027] Example 1

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4A drainage tube seepage collection device includes a bag body 1, the top of the bag body 1 is connected to a folded fan 4, the top of the folded fan 4 is connected to a telescopic access tube 5, and a drainage tube body 6 is inserted into the top of the telescopic access tube 5; a mounting shell 7 is provided on the front side of the telescopic access tube 5, and a binding component 14 is provided inside the mounting shell 7 for tightening the section where the drainage tube body 6 and the telescopic access tube 5 are inserted; one end of the binding component 14 is sleeved on the end where the telescopic access tube 5 and the drainage tube body 6 are inserted.

[0029] Please see Figure 1 and Figure 2 , Figure 3 The binding assembly 14 includes a binding strap 8, and the inner wall of the mounting shell 7 is connected to one end of the binding strap 8. A take-up shaft 10 is rotatably connected to the inner cavity of the mounting shell 7. The other end of the binding strap 8 is wound around the end of the telescopic access tube 5 that is inserted into the drainage tube body 6, and then wrapped around the surface of the take-up shaft 10. Connecting blocks 11 are connected to the top and bottom of the take-up shaft 10. A worm spring 12 for driving the take-up shaft to rotate is connected to the surface of the connecting block 11. By setting the worm spring 12, it is easy to drive the connecting block 11 and the take-up shaft 10 to rotate, and it is easy to retract the binding strap 8.

[0030] In this embodiment, the worm spring (12) is always kept in the winding state, that is, the worm spring 12 in the winding state always tends to tighten the strap 8.

[0031] In this embodiment, the mounting shell 7 is provided with a retractable opening, and one end of the strap 8 is connected to an inner wall of the retractable opening; the other end of the strap 8 passes over the telescopic access tube 5 and then winds around the surface of the take-up shaft 10 through the retractable opening. Driven by the worm spring 12 in the winding state, the take-up shaft 1 rotates to tighten the strap.

[0032] Please see Figure 2 The mounting housing 7 has fixed covers 9 installed at both its top and bottom; the two ends of the winding shaft 10 are rotatably connected to the fixed covers 9 at the top and bottom of the mounting housing 7, respectively. The winding shaft 10 is rotatably disposed inside the mounting housing 7.

[0033] Please see Figure 3 The strap 8 has a pull block 13 on its rear side, and one end of the spiral spring 12 is connected to the block 11; the other end of the spiral spring 12 is connected to the fixing cover 9. The pull block 13 facilitates the user's pulling out of the strap 8, allowing it to be easily fitted onto the section where the drainage tube body 6 and the telescopic access tube 5 intersect. The end of the spiral spring 12 away from the connecting block 11 is welded to the fixing cover 9. The section where the drainage tube body 6 and the telescopic access tube 5 intersect is the section where they intersect after being inserted.

[0034] Please see Figure 1 The telescopic access tube 5 is made of hydrocolloid dressing. The surface of the drainage tube body 6 is provided with a limiting structure 16 for limiting the depth of the drainage tube body 6 inserted into the telescopic access tube 5. By setting the limiting structure 16, the drainage tube body 6 can be easily limited, which can effectively prevent the drainage tube body 6 from being inserted too much into the bag body 1.

[0035] Please see Figure 1 The front side of the bag body 1 is connected to a drain pipe 2. By setting the drain pipe 2, it is easy to drain the seepage inside the bag body 1. A sealing plug 3 is inserted into the front side of the drain pipe 2. By setting the sealing plug 3, it is easy to seal the drain pipe 2, which can effectively prevent the seepage inside the bag body 1 from spilling out.

[0036] Please see Figure 1 and Figure 2 The surface of the sealing plug 3 is provided with anti-leakage grooves, and the corresponding sewage pipe 2 is provided with threads corresponding to the anti-leakage screw; by setting the anti-leakage grooves, it is possible to effectively prevent the leakage of liquid from the bag body 1. The front side of the sealing plug 3 is glued with a pull head, which makes it easy to pull the sewage pipe 2.

[0037] Please see Figure 1 , Figure 4 The folding fan surface 4 includes several skeletons 17 with a certain degree of extension. Each skeleton 17 is radiating outwards from the telescopic access tube 5, with one end connected to the telescopic access tube 5. Fan surfaces 18 with certain folds are provided between adjacent skeletons 17. When the telescopic access tube 5 is lifted, the weight of the seepage in the bag causes the folding fan surface 4 to fold, creating a bulge and preventing the seepage from flowing out of the bag 1. The main function of the skeletons 17 is to bear the weight.

[0038] Please see Figure 5 The bottom surface of the bag body 1 is provided with a silicone block 20 with a drainage hole 19. The silicone block 20 can be rolled outward from the edge of the drainage hole 19. A medical rubber ring 21 is also provided along the outer edge of the silicone block 20. The position of the drainage hole 19 corresponds to the position of the telescopic access tube 5.

[0039] Before use, medical staff only need to roll and fold the original drainage hole 19 outward to enlarge its diameter to match the diameter of the telescopic access tube 5. Furthermore, when the drainage tube body 6 is inserted into the drainage hole 19 through the telescopic access tube 5, the edge of the drainage hole 19 fits tightly against the outer wall of the drainage tube, thus creating a seal and preventing leakage of excrement. Moreover, the medical rubber ring 21 and the silicone block are located on the same side of the bag, ensuring that the drainage hole 19 faces the body when the bag is held on the person, guaranteeing smooth delivery of the tube.

[0040] In this embodiment, the upper surface of the silicone block 21 is provided with several annular grooves 22 that are concentric with the drainage holes 19.

[0041] Since the bottom thickness of the annular groove is often much smaller than the original thickness of the silicone block, the silicone block is more flexible in the groove. Moreover, the large number of grooves makes it easier for medical staff to flip the edge of the drainage hole.

[0042] Please see Figure 4 , Figure 5 In use, the bottom of the bag faces the patient. Pulling the pull block 13 pulls the strap 8 out of the mounting shell 7. Then, the strap 8 is placed over the surface of the telescopic access tube 5. The drainage tube to be used is inserted into the telescopic access tube 5 and passes through the drainage hole 19, the edge of which is tightly against the outer wall of the drainage tube. Then, the pull block 13 is released, and the connecting block 11 and the winding shaft 10 are rotated by the elastic force of the spiral spring 12. The rotation of the winding shaft 10 retracts the strap 8, tightening the telescopic access tube 5 and securing the drainage tube body 6. The bag 1 is then fixed to the patient by the medical rubber ring 21 on the bottom surface of the bag 1.

[0043] In actual use, some of the seepage will flow into the bag body through the gap between the outer surface of the drainage tube and the silicone block 20 to prevent the seepage from flowing out. At the same time, the drainage tube is tightened by the binding assembly 14 to prevent the seepage from flowing out between the telescopic access tube (5) and the main body of the drainage tube.

[0044] After use, the main body 6 of the drainage tube is pulled out from the telescopic access tube 5, and then the binding strap 8 is continuously tightened by the winding shaft 10 to seal the telescopic access tube 5. Then, the bag body 1 is lifted by pulling the telescopic access tube 5. After the telescopic access tube 5 is lifted, the folding fan 4 will fold due to gravity, causing the folding fan 4 to bulge, preventing the seepage from the bag body 1. Then, the sealing plug 3 can be pulled out from the drain pipe 2 to drain the seepage from the bag body 1.

[0045] In summary, this drainage tube exudate collection device, through the fixed cover 9, winding shaft 10, connecting block 11, spiral spring 12, pull block 13, and binding assembly 14, solves the problem that the main body size of the drainage tube is fixed during use, making it inconvenient to insert drainage tubes of different sizes into the telescopic access tube, which is not convenient for different patients and reduces the applicability of the device.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
