[0022] This application provides a colostomy care device after colorectal surgery. In its initial state, when the user has not installed the ostomy bag, the slider on the outside of the movable shell is located at the top of the straight sliding groove due to the action of the spring, and the ball is located at one end of the inclined arc groove. At this time, the two sets of semi-sealed grooves are in contact with each other, which can prevent external impurities from entering the interior of the semi-sealed grooves.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0038] like Figures 1-7 As shown, this application provides a colostomy care device after colorectal surgery, including a medical adhesive tape 1. One end of the medical adhesive tape 1 is fixedly connected to a base plate 2. A fixing shell 13 is fixedly connected to the front surface of the base plate 2. An ostomy bag 9 is provided on the front surface of the fixing shell 13. A sealing ring 32 is fixedly connected to the port of the ostomy bag 9. The sealing ring 32 is made of silicone. A driving component is provided on the outside of the fixing shell 13 for convenient fixing and sealing of the sealing ring 32. The driving component includes a rotating shell 22 rotatably connected to the front surface of the base plate 2.

[0039] Two sets of oblique arc-shaped grooves 18 are formed on the outside of the fixed shell 13.

[0040] The movable shell 23 is located outside the fixed shell 13 and inside the rotating shell 22. The outer side of the movable shell 23 is rotatably connected with ball bearings 24. There are two sets of ball bearings 24. The ball bearings 24 are slidably connected to the inner side of the inclined arc groove 18.

[0041] A straight sliding groove 30 is formed inside the rotating shell 22. There are two sets of straight sliding grooves 30. A slider 31 is slidably connected inside both sets of straight sliding grooves 30. Both sets of sliders 31 are fixedly connected to the outside of the movable shell 23.

[0042] A spring 12 is installed at the rotating connection of the rotating housing 22, and the end of the spring 12 is fixedly connected to the front surface of the chassis 2.

[0043] Both the movable shell 23 and the fixed shell 13 have a semi-sealing groove 21 at one end, and the two sets of semi-sealing grooves 21 are matched with the sealing ring 32 after being put together.

[0044] In this embodiment, in the initial state, when the user has not installed the ostomy bag 9, due to the action of the spring 12, the slider 31 on the outside of the movable shell 23 is located at the top of the straight sliding groove 30, and the ball 24 is located at one end of the inclined arc groove 18. At this time, the two sets of semi-sealed grooves 21 are in contact with each other, which can prevent external impurities from entering the interior of the semi-sealed grooves 21. When the user needs to install the ostomy bag 9, the rotating shell 22 is rotated, causing the slider 31 to move downward along the straight sliding groove 30, and the ball 24 to move to the other end along the inner side of the inclined arc groove 18. That is, the movable shell 23 moves downward so that the two sets of semi-sealed grooves 21 are no longer in contact. During this process, the spring 12 simultaneously becomes taut. In this state, the sealing ring 32 at the port of the ostomy bag 9 is inserted into the semi-sealing groove 21, and then the rotating shell 22 is released. The elastic potential energy accumulated by the spring 12 will cause the rotating shell 22 to return to its original position, thereby causing the two sets of semi-sealing grooves 21 to clamp and seal the sealing ring 32. This design can enhance the sealing and stability of the installation position when installing the ostomy bag 9, and when the ostomy bag 9 is not installed, the sealing groove is closed to prevent the inside from being contaminated, ensuring the cleanliness and protection of the interface throughout the process. When installing the ostomy bag 9, the medical adhesive 1 with the base plate 2 needs to be applied to the designated position before installing the ostomy bag 9. Since silicone has excellent elastic deformation and resilience, the sealing ring 32 is made of silicone.

[0045] like Figure 1 , 2 As shown in Figures 7 and 8, the outer side of the ostomy bag 9 is provided with an annular pleated section 11, and the outer side of the ostomy bag 9 is wrapped with a pull strap 10 located outside the annular pleated section 11.

[0046] In this embodiment, the core function of the ostomy bag 9 is to collect and store feces discharged from the abdominal wall stoma after colorectal or bladder surgery. When the user needs to remove the ostomy bag 9 containing feces, in order to prevent the feces from spilling out due to accidental contact during removal, the pull strap 10 needs to be pulled in advance. The pull strap 10 will cause the annular pleated section 11 to tighten, thereby tightening the port of the ostomy bag 9, and then the ostomy bag 9 can be removed, thus preventing the feces from spilling out. The ostomy bag 9 is a disposable medical-grade polyethylene product, and since the material cost and process cost of the annular pleated section 11 and the pull strap 10 are extremely low, this design can balance functional improvement and economy.

[0047] like Figures 1-9 As shown, a mounting block 14 is fixedly connected to one side of the chassis 2. A cylindrical groove 15 is provided on the top of the mounting block 14. A first rotating groove 17 communicating with the cylindrical groove 15 is provided inside the mounting block 14. A connecting groove 16 communicating with the cylindrical groove 15 is provided on one side of the mounting block 14. The connecting groove 16 is connected with the first rotating groove 17.

[0048] A belt 3 is provided on one side of the chassis 2. One end of the belt 3 is fixedly connected to a connecting rod 39 that matches the connecting groove 16. The connecting rod 39 matches the first rotating groove 17. One end of the connecting rod 39 is fixedly connected to a cylinder 38 that matches the cylindrical groove 15.

[0049] A telescopic rod 27 is rotatably connected to the outside of the rotating shell 22. One end of the telescopic rod 27 is fixedly connected to a sealing plate 26 that matches the cylindrical groove 15. A torsion spring 28 is installed at the rotatable connection of the telescopic rod 27. The end of the torsion spring 28 is fixedly connected to the outside of the rotating shell 22. A limiting block 25 located on one side of the telescopic rod 27 is fixedly connected to the outside of the rotating shell 22.

[0050] A fixing block 8 is fixedly connected to the other side of the chassis 2. A buckle 6 matching the waist belt 3 is fixedly connected to the front surface of the fixing block 8. A Velcro hook surface 4 is provided on one side of the waist belt 3. A Velcro nap surface 5 matching the Velcro hook surface 4 is provided on one side of the waist belt 3. Multiple sets of equally spaced limiting protrusions 29 are fixedly connected to the outer side of the rotating shell 22.

[0051] The front surface of the fixing block 8 is provided with a second rotating groove 19 that communicates with the inner cavity of the sleeve 6. The top of the fixing block 8 is provided with a rectangular groove 20 that communicates with the second rotating groove 19. The bottom end of the second rotating groove 19 is rotatably connected to a connecting shaft 33 that passes through the rectangular groove 20. The top of the connecting shaft 33 is fixedly connected to a knob 7. The outer side of the connecting shaft 33 is fixedly connected to an eccentric wheel 37 located inside the rectangular groove 20. The eccentric wheel 37 is made of a hard elastic material. The fixed connection point of the connecting shaft 33 is located at a position off-circular from the eccentric wheel 37. The outer side of the connecting shaft 33 is fixedly connected to a first top plate 34.

[0052] A first top plate 34 is fixedly connected to the outer side of the connecting shaft 33, and a limiting tooth plate 36 that matches the limiting protrusion 29 is fixedly connected to the outer side of the connecting shaft 33. A second top plate 35 is fixedly connected to one side of the limiting tooth plate 36.

[0053] In this embodiment, when the user installs the ostomy bag 9, the rotating shell 22 needs to be rotated so that the slider 31 is located at the bottom end of the straight sliding groove 30, and the ball bearing 24 is located at one end of the bottom of the inner side of the inclined arc groove 18. At this time, the sealing plate 26 has not yet sealed the cylindrical groove 15. The user can then simultaneously install the waist belt 3 assembly. When installing the waist belt 3 assembly, the cylinder 38 on one side of the waist belt 3 is inserted into the cylindrical groove 15, and the connecting rod 39 slides synchronously inside the connecting groove 16 until the connecting rod 39 slides into the inside of the first rotating groove 17. The waist belt 3 is then installed. When the user has installed the waist belt 3 and the ostomy bag 9, the user can release the... When the housing 22 rotates, the sealing plate 26 simultaneously seals the top of the cylindrical groove 15. Due to the elasticity of the torsion spring 28 and the action of the limiting block 25, the sealing plate 26 is always at the angle of engagement with the cylindrical groove 15 during the rotation of the housing 22. When the ostomy bag 9 is not installed and the two sets of semi-sealed grooves 21 begin to close, the housing 22 needs a certain distance of transitional rotation. Therefore, after the sealing plate 26 seals the cylindrical groove 15, the telescopic rod 27 rotates synchronously and adaptively extends and retracts to maintain the sealing effect of the sealing plate 26 on the cylindrical groove 15. This design can connect the waist belt 3 assembly and the ostomy bag 9 assembly. The installation and fixing are integrated. After the user installs the waist belt 3, the other end of the waist belt 3 is passed through the buckle 6, and the hook and loop side 5 of the Velcro is attached to the hook and loop side 4 to complete the initial fixing of the waist belt 3. When the user needs to strengthen the locking and fixing effect of the waist belt 3 and the rotating shell 22, the knob 7 is turned so that the connecting shaft 33 with the eccentric wheel 37 rotates synchronously. The first top plate 34 on the connecting shaft 33 will begin to press and fix the waist belt 3, and the limiting tooth plate 36 on the connecting shaft 33 will begin to engage with the limiting protrusion 29 on the outside of the rotating shell 22, that is, to strengthen the locking strength of the rotating shell 22. At the same time, the second top plate 35 begins to press. After installation, the ostomy bag 9 is fixed to strengthen the fixation of the ostomy bag 9. During the rotation of the connecting shaft 33, the eccentric wheel 37 rotates synchronously inside the rectangular groove 20 and begins to squeeze the inside of the rectangular groove 20 and deforms. The elastic potential energy generated by the deformation of the eccentric wheel 37 will stabilize the connecting shaft 33 in this state, thereby stabilizing and strengthening the locking and fixing effect of the waist belt 3 and the rotating shell 22. Since the eccentric wheel 37 is made of hard elastic material, it can provide stable pushing and locking support by relying on the hardness of the base material, ensuring that the waist belt 3 is locked firmly and not easy to loosen or deform; and it can also achieve smooth locking and fitting by utilizing the slight elastic deformation of the material.

[0054] Working Principle: This device is similar to the ZKD-2 type adhesive ostomy bag. Its core function is to collect and store feces discharged from the stoma, isolate excrement from the skin, prevent leakage and odor, protect the skin around the stoma, and meet the daily excretion and care needs of patients. It is easy to operate and is an essential nursing product after stoma surgery. In the initial state, when the user has not installed the ostomy bag 9, due to the action of the spring 12, the slider 31 on the outside of the moving shell 23 is located at the top of the straight sliding groove 30, and the ball 24 is located at one end of the inclined arc groove 18. At this time, the two sets of semi-sealed grooves 21 are in contact with each other, which can prevent external impurities from entering the interior of the semi-sealed grooves 21. When the user needs to install the ostomy bag 9, the rotating shell 22 is rotated, so that the slider 31 moves along the straight groove 20. The sliding groove 30 moves downward, and the ball bearing 24 moves along the inner side of the inclined arc groove 18 to the other end, that is, the moving shell 23 moves downward so that the two sets of semi-sealed grooves 21 no longer fit together. During this process, the spring 12 simultaneously becomes taut, and the sealing ring 32 at the port of the ostomy bag 9 is put into the semi-sealed groove 21. Then the rotating shell 22 is released, and the elastic potential energy accumulated by the spring 12 will cause the rotating shell 22 to return to its original position, thereby causing the two sets of semi-sealed grooves 21 to clamp and seal the sealing ring 32. When installing the ostomy bag 9, the medical adhesive 1 with the base plate 2 needs to be applied to the designated position before installing the ostomy bag 9. Since silicone has excellent elastic deformation and resilience, the sealing ring 32 is made of silicone. When the user needs to remove the ostomy bag 9 containing feces, in order to To prevent fecal spillage during disassembly, the pull strap 10 needs to be pulled beforehand. The pull strap 10 will tighten the annular pleated section 11, thereby tightening the port of the ostomy bag 9, allowing the ostomy bag 9 to be removed immediately and preventing fecal spillage. When the user installs the ostomy bag 9, the rotating shell 22 needs to be rotated so that the slider 31 is at the bottom of the straight sliding groove 30, and the ball bearing 24 is at one end of the bottom of the inclined arc groove 18. At this time, the sealing plate 26 has not yet sealed the cylindrical groove 15, and the user can simultaneously install the waist belt 3 assembly. When installing the waist belt 3 assembly, insert the cylinder 38 on one side of the waist belt 3 into the cylindrical groove 15, and the connecting rod 39 slides simultaneously inside the connecting groove 16 until the connecting rod 39 slides into the inside of the first rotating groove 17, at which point the waist belt is installed. When the user has installed the waist belt 3 and ostomy bag 9, and releases the rotating shell 22, the sealing plate 26 simultaneously seals the top of the cylindrical groove 15. Due to the elasticity of the torsion spring 28 and the action of the limiting block 25, the sealing plate 26 will always be at the angle of engagement with the cylindrical groove 15 during the rotation of the rotating shell 22. When the ostomy bag 9 is not installed and the two sets of semi-sealed grooves 21 begin to close, the rotating shell 22 needs a certain amount of transitional rotation. Therefore, after the sealing plate 26 seals the cylindrical groove 15, the telescopic rod 27 rotates synchronously and adaptively extends and retracts to maintain the sealing effect of the sealing plate 26 on the cylindrical groove 15. After the user has installed the waist belt 3, the other end of the waist belt 3 is passed through the buckle 6, and the Velcro loop 5 and the Velcro hook 4 are attached together.This completes the initial fixation of the waist belt 3. When the user needs to strengthen the locking and fixing effect of the waist belt 3 and the rotating shell 22, turning the knob 7 causes the connecting shaft 33 with the eccentric wheel 37 to rotate synchronously. The first top plate 34 on the connecting shaft 33 will begin to press and fix the waist belt 3, and the limiting tooth plate 36 on the connecting shaft 33 will begin to engage with the limiting protrusion 29 on the outside of the rotating shell 22, thus strengthening the locking strength of the rotating shell 22. At the same time, the second top plate 35 begins to press the installed ostomy bag 9 to strengthen the fixation of the ostomy bag 9 after installation. During the rotation of the connecting shaft 33, the eccentric wheel 37 rotates synchronously inside the rectangular groove 20 and begins to press and deform inside the rectangular groove 20. The elastic potential energy generated by the deformation of the eccentric wheel 37 will stabilize the connecting shaft 33 in this state. Since the eccentric wheel 37 is made of a hard elastic material, it can provide stable pushing and locking support by relying on the hardness of the base material, ensuring that the waist belt 3 is firmly locked and not easy to loosen or deform; it can also achieve smooth locking and fitting by utilizing the slight elastic deformation of the material.
