[0025] Example 1

[0026] Please refer to Figure 1 — Figure 3 The utility model discloses a sigmoid colostomy expansion ware, including sleeve unit 100 and the pipe body unit 200 of fixed connection at the top of sleeve unit 100, still including setting inflation unit 300 on sleeve unit 100 and pipe body unit 200 and setting plugging unit 400 at the bottom of sleeve unit 100;

[0027] The sealing unit 400 includes a connecting rod 404 movably disposed at the bottom of the outer casing unit 100, and a sealing plug 405 fixedly connected to the top of one end of the connecting rod 404 for opening and closing the outer casing unit 100.

[0028] The outer cover unit 100 includes an outer cover pad 101, a through opening 102 that extends through the center of the top of the outer cover pad 101, and a spring groove 103 that extends into the bottom of one side of the outer cover pad 101.

[0029] The tube unit 200 includes an expansion tube 201 fixedly connected to the top of the outer gasket 101, and an annular threaded groove 202 formed on the outer surface of the expansion tube 201. The inner diameter of the expansion tube 201 is adapted to the inner diameter of the top end of the through port 102.

[0030] like Figure 1 and Figure 2 As shown, the inflation unit 300 includes an inflatable balloon tube 303 wound inside the outer surface of the tube unit 200, and a close-fitting ring pad 304 fitted on the outer surface of the tube unit 200 for close contact with the stoma intestinal wall. The inflation unit 300 also includes an air supply tube 302 inserted inside the outer pad 101, and a press-inflation balloon 301 fixedly connected to one end of the air supply tube 302. The other end of the air supply tube 302 is fixedly connected to one end of the inflatable balloon tube 303. The inflatable balloon tube 303 is wound inside the annular threaded groove 202, and the outer surface of the inflatable balloon tube 303 is fixedly connected to the inner wall of the close-fitting ring pad 304.

[0031] Working principle: In the initial state, the inflatable balloon tube 303 is in a contracted state. Then, the dilator tube 201 is inserted into the colostomy, and the outer pad 101 is attached to the outside of the stoma. Then, by pressing the inflatable balloon 301, gas is sent into the inflatable balloon tube 303 through the gas supply tube 302, causing the inside of the inflatable balloon tube 303 to inflate and expand inside the annular threaded groove 202. The expansion of the inflatable balloon tube 303 will squeeze the annular pad 304 outward, so that the annular pad 304 is in full contact with the colon wall and adheres tightly. In this way, the dilator tube 201 is stabilized inside the colostomy. This structure ensures the stability of the dilator tube 201 during use by inflating it to keep it tightly attached to the inner wall of the colostomy, avoiding loosening and falling off, and improving the practicality of the dilator.

[0032] Example 2

[0033] Please refer to Figure 1 — Figure 3As shown, this utility model is a sigmoid colostomy dilator, including an outer sleeve unit 100 and a tube unit 200 fixedly connected to the top of the outer sleeve unit 100, as well as an inflation unit 300 disposed on the outer sleeve unit 100 and the tube unit 200 and a sealing unit 400 disposed at the bottom of the outer sleeve unit 100.

[0034] The inflation unit 300 includes an inflatable balloon tube 303 wrapped inside the outer surface of the tube unit 200, and a close-fitting ring pad 304 fitted on the outer surface of the tube unit 200 for close contact with the stoma intestinal wall.

[0035] The outer cover unit 100 includes an outer cover pad 101, a through opening 102 that extends through the center of the top of the outer cover pad 101, and a spring groove 103 that extends into the bottom of one side of the outer cover pad 101.

[0036] The tube unit 200 includes an expansion tube 201 fixedly connected to the top of the outer gasket 101, and an annular threaded groove 202 formed on the outer surface of the expansion tube 201. The inner diameter of the expansion tube 201 is adapted to the inner diameter of the top end of the through port 102.

[0037] like Figure 1 and Figure 3 As shown, the sealing unit 400 includes a connecting rod 404 movably disposed at the bottom of the outer sleeve unit 100, and a sealing plug 405 fixedly connected to the top of one end of the connecting rod 404 for opening and closing the outer sleeve unit 100. The sealing unit 400 also includes a limiting movable plate 401 movably disposed inside the spring groove 103, a movable rod 402 fixedly connected to the center of the bottom of the limiting movable plate 401, a return spring 403 sleeved on the outer surface of the movable rod 402, and a pull-down ring 406 fixedly connected to the bottom of the connecting rod 404. One side of the bottom end of the movable rod 402 is fixedly connected to one end of the connecting rod 404. The outer diameter of the top end of the sealing plug 405 is adapted to the inner diameter of the bottom end of the through port 102. The return spring 403 is fixedly connected between the bottom of the limiting movable plate 401 and the inner bottom wall of the spring groove 103.

[0038] Working principle: In the initial state, the sealing plug 405 seals the through-hole 102 of the outer pad 101. After the expansion tube 201 is installed, the sealing plug 405 is pulled away from the through-hole 102 by the pull-down ring 406, creating a flow state for easy defecation. During the pull-down process, the pull-down ring 406 drives the connecting rod 404 to descend, which in turn drives the movable rod 402 to descend. The descent of the movable rod 402 causes the limiting movable plate 401 to descend inside the spring groove 103. The descent of the limiting movable plate 401 compresses the return spring 403 on the outer surface of the movable rod 402. Then, rotating the sealing plug 405 to the other side completely opens the through-hole 102. Conversely, the elastic recovery of the return spring 403 allows the sealing plug 405 to align with the through-hole 102 and enter for sealing. This structure can quickly and effectively seal and open the expansion tube 201, facilitating defecation operations in colostomy and benefiting medical staff.
