Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ostomy bag technology, and specifically relates to an ostomy bag that is easy to assemble and disassemble. Background Technology
[0002] Ostomy bags are mainly used by ostomy patients to collect urine or feces. Current ostomy bags include one-piece and two-piece designs. One-piece ostomy bags have an adhesive section integrated with the bag body; once removed, they are discarded and are for single use. Two-piece ostomy bags have a separate adhesive section and bag body; the bag body is detached and connected to the adhesive section. Therefore, during cleaning, only the bag body needs to be removed, cleaned, and reattached to the adhesive section for reuse. The drawback of two-piece ostomy bags is that the adhesive section and bag body are connected by snaps, making disassembly and assembly difficult, especially for patients with limited mobility, posing a significant problem when changing the ostomy bag. Utility Model Content
[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an ostomy bag that is easy to assemble and disassemble, so as to solve the problems existing in the above-mentioned background art.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] An easily detachable ostomy bag includes a movable transition chamber with a flexible absorbent pad detachably connected to its inner side. The flexible absorbent pad adheres the movable transition chamber to the stoma. The flexible absorbent pad has an outlet that communicates with the inner cavity of the movable transition chamber. When the flexible absorbent pad is attached to the stoma, the edge of the outlet is attached to the edge of the stoma, so that the stoma is placed inside the inner cavity of the movable transition chamber. A cleaning window is provided on the outer side of the movable transition chamber, and a sealing cap is detachably connected to the cleaning window. A drain outlet is provided at the bottom of the movable transition chamber, and the ostomy bag body is provided on the drain outlet.
[0006] As a preferred technical solution, the flexible adsorption pad is made of silicone.
[0007] As a preferred technical solution, the flexible adsorption pad includes a flexible snap ring, one side edge of which protrudes outward to form a spherical surface, the outlet is opened at the center of the spherical surface, and the bottom edge of the spherical surface extends to form a suction cup-shaped adsorption edge.
[0008] The spherical structure allows for a closer fit between the protruding spherical structure and the skin surface when the outlet is attached to the stoma.
[0009] As a preferred technical solution, a snap-fit groove is provided on the inner side ring wall of the mobile transition chamber, and the flexible snap-fit ring snaps into the snap-fit groove.
[0010] As a preferred technical solution, the flexible snap ring has an integrally formed protruding snap-fit part, and correspondingly, a snap-fit groove matching the snap-fit part is formed in the snap-fit groove. During installation, the snap-fit part is placed in the snap-fit groove, making the connection more stable and convenient.
[0011] As a preferred technical solution, the sealing cap is threadedly connected to the cleaning window.
[0012] As a preferred technical solution, the inlet end of the ostomy bag is provided with a connecting section, the side wall of the connecting section is provided with a protrusion, and the outer wall of the discharge port is provided with an L-shaped groove. The protrusion is engaged in the L-shaped groove to detachably connect the ostomy bag to the discharge port.
[0013] As a preferred technical solution, it also includes a fixed adjustment belt, and adjustment belt fixing frames are provided on both sides of the movable transition chamber, with the fixed adjustment belt connected to the adjustment belt fixing frames.
[0014] In summary, the present invention has the following main advantages:
[0015] This application incorporates a movable transition chamber that connects to the ostomy bag body, making the ostomy bag body easier to disassemble. In addition, the flexible absorbent pad forms a spherical structure with the end that fits against the body, resulting in higher sealing performance and preventing leakage.

[0022] Example
[0023] refer to Figures 1 to 6This embodiment of an ostomy bag that is easy to assemble and disassemble includes a movable transition chamber 1. A flexible adsorption pad 2 is detachably connected to the inner side of the movable transition chamber. The movable transition chamber is adsorbed onto the stoma by the flexible adsorption pad. An outlet 3 is provided on the flexible adsorption pad, which communicates with the inner cavity of the movable transition chamber. When the flexible adsorption pad is attached to the stoma, the edge of the outlet is attached to the edge of the stoma, so that the stoma is placed inside the inner cavity of the movable transition chamber. A cleaning window 4 is provided on the outer side of the movable transition chamber, and a sealing cap 5 is detachably connected to the cleaning window. A discharge port 6 is provided at the bottom of the movable transition chamber, and an ostomy bag body 7 is provided on the discharge port.
[0024] Specifically, the flexible suction pad is made of silicone and includes a flexible snap ring 8. One edge of the flexible snap ring protrudes outward to form a spherical surface 9. The outlet is located at the center of the spherical surface, and the bottom edge of the spherical surface extends to form a suction cup-shaped suction edge 10. The spherical structure allows the protruding spherical structure to adhere more tightly to the skin surface when the outlet is attached to the stoma.
[0025] A snap-fit groove 11 is provided on the inner side ring wall of the mobile transition compartment. The flexible snap-fit ring snaps into the snap-fit groove. The flexible snap-fit ring has an integrally formed protruding fastening part 12. Correspondingly, a fastening groove 13 matching the fastening part is formed in the snap-fit groove. During installation, the fastening part is placed in the fastening groove, making the connection more stable and convenient.
[0026] The sealing cap is threadedly connected to the cleaning window.
[0027] The ostomy bag body has a connecting section 14 at the inlet end, a protrusion 15 on the side wall of the connecting section, and an L-shaped groove 16 on the outer wall of the discharge port. The protrusion is engaged in the L-shaped groove to detachably connect the ostomy bag body to the discharge port.
[0028] It also includes a fixed adjustment belt, and adjustment belt fixing frames are provided on both sides of the movable transition chamber, with the fixed adjustment belt connected to the adjustment belt fixing frames.
