[0028] Please also refer to Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a drainage device 10. The drainage device 10 includes a first drainage component 100 and a second drainage component 200.

[0029] The first drainage component 100 has a columnar structure. The first drainage component 100 has a first end surface 110 and a second end surface 120 at each end, with the second end surface 120 being a closed end surface structure. The outer peripheral surface of the first drainage component 100 has a drainage groove 130, which also opens onto the first end surface 110. That is, the drainage groove 130 opens onto the outer peripheral surface of the first drainage component 100 and the first end surface 110, but does not open onto the second end surface 120. Since the second end surface 120 is located inside the anus when the drainage device 10 is in use, the closed second end surface 120 prevents feces from the anus from entering the drainage groove 130.

[0030] The second drainage member 200 is a hollow tubular structure with two open ends. It extends through the first drainage member 100 from the first end face 110 to the second end face 120. The second drainage member 200 is designed to drain feces from the anus and separate it from exudate from the anal wound.

[0031] In one embodiment, the first flow guiding member 100 has a cylindrical structure. It is understood that in other embodiments, the structure and shape of the first flow guiding member 100 are not limited to the above. The structure and shape of the first flow guiding member 100 may also be an elliptical cylinder, that is, the radial cross-section of the first flow guiding member 100 is elliptical. In other embodiments, the structure of the first flow guiding member 100 may also be a structure with a smoothly curved outer surface protruding outward.

[0032] In one embodiment, the drainage groove 130 is arranged around the outer circumference of the first drainage component 100. Figure 4 As shown, the drainage groove 130 surrounds the outer circumference of the first drainage member 100 for at least one revolution. Preferably, each drainage groove 130 surrounds the outer circumference of the first drainage member 100 from the first end surface 110 to the second end surface 120, but does not open to the second end surface 120. Multiple drainage grooves may be arranged side by side around the outer circumference of the first drainage member 100.

[0033] In one embodiment, there are multiple drainage grooves 130. The multiple drainage grooves 130 are evenly distributed on the first end surface 110. Figure 1 and Figure 3 As shown, there are four drainage grooves 130. It is easy to understand that in other embodiments, the number of drainage grooves 130 can also be other numbers, such as two, three, five, etc.

[0034] In one embodiment, the inner dimension of the drainage groove 130 is larger than the notch dimension of the drainage groove 130 located on the outer circumference of the first drainage component 100, that is, the cross-sectional dimension of the drainage groove 130 is a structure with a larger inner portion and a smaller outer portion, see Figure 3As shown, the drainage groove 130 on the outer circumference of the first drainage component 100 has a smaller opening, while the interior of the drainage groove 130 has a larger opening. This arrangement can reduce the size of the opening on the outer circumference of the first drainage component 100, allowing the outer circumference of the first drainage component 100 to contact the user's anal skin over a larger area, reducing the user's foreign body sensation and scratching sensation during use.

[0035] In one embodiment, the first drainage member 100 is made of a soft material, which allows it to be elastic. For example, the first drainage member 100 can be made of a soft, deformable material such as silicone or elastic plastic. The flexibility of the first drainage member 100 facilitates movement of the anal skin. For example, after anal surgery, when a user has the drainage device 10 placed in their anus, movement of the skin at the anus can interact with the soft first drainage member 100, reducing discomfort.

[0036] In one embodiment, the second drainage component 200 is made of a metal material and has a non-deformable structure. The drainage device 10 of the present invention comprises a first drainage component 100 made of a soft material. The softness of the first drainage component 100 facilitates user use and enhances user comfort. The second drainage component 200 is made of a metal material, which enhances the strength of the entire drainage device 10, prevents deformation during use, and effectively ensures the therapeutic effect.

[0037] In one embodiment, the ends of the second drainage component 200 protrude from the first end surface 110 and the second end surface 120, respectively. The arrangement of the second drainage component 200 protruding from the first end surface 110 and the second end surface 120, respectively, facilitates the discharge of feces from the anus and maintains an appropriate distance from the drainage groove 130. The distance by which the ends of the second drainage component 200 protrude from the first end surface 110 and the second end surface 120, respectively, can be between 1 cm and 2 cm. For example, the distance by which the ends of the second drainage component 200 protrude from the first end surface 110 and the second end surface 120, respectively, can be 1 cm, 2 cm, or other values. The distance by which the ends of the second drainage component 200 protrude from the first end surface 110 and the second end surface 120, respectively, should not be too large. If it is too large, it will affect the use of the entire drainage device 10 and increase the user's discomfort and foreign body sensation. The distance between the two ends of the second drainage component 200 protruding from the first end surface 110 and the second end surface 120 should not be too small. If it is too small, it will not be conducive to creating a suitable distance between the second drainage component 200 and the drainage groove 130, affecting the drainage effect.

[0038] In one embodiment, the drainage device 10 of the present invention further includes anti-skid fins 300. These fins 300 are attached to the outer circumference of the first drainage component 100 and are flush with the first end surface 110. The radial dimensions of the anti-skid fins 300 are larger than those of the first drainage component 100. The drainage device 10 of the present invention includes the anti-skid fins 300 on the first drainage component 100 to prevent the drainage device 10 from slipping into the anus.

[0039] The anti-skid fins 300 are made of a soft material, which allows them to be flexible. For example, the anti-skid fins 300 can be made of a soft, deformable material such as silicone or elastic plastic, allowing for free deformation. Furthermore, the anti-skid fins 300 and the first drainage component 100 can be integrally formed, connected to form a one-piece structure, facilitating integrated manufacturing.

[0040] In one embodiment, the drainage device 10 of the present invention further includes a traction cord 400 connected to the anti-slip tail 300. The traction cord 400 is attached to the anti-slip tail 300. The traction cord 400 can be adhered to the skin around the anus to facilitate securing the position of the drainage device 10. The traction cord 400 can be made of conventional yarn used in the medical field, which is low-cost and readily available.

[0041] In summary, the drainage device 10 of the present invention has excellent drainage effects and can effectively shorten the postoperative recovery period. The drainage device 10 of the present invention can guide anal wound exudate into the drainage groove 130 for discharge through the first drainage component 100. Because the second end surface 120 is a closed end surface, feces can only be discharged through the second drainage component 200 and will not enter the drainage groove 130. The first drainage component 100 and the second drainage component 200 achieve separation of anal wound exudate and feces in the rectum, thereby reducing the chance of anal wound infection.
