[0034] Please refer to Figures 1-3 This embodiment provides an ostomy bag 100, which includes a base plate 110, an annular connector 120, and a bag body connector 130.

[0035] The chassis 110 includes a first channel 111; an annular connector 120 is movably connected to the chassis 110 along the extension direction of the first channel 111; and a bag connector 130 is connected to the annular connector 120.

[0036] The annular connector 120 has a second channel 121 that communicates with the first channel 111, and the bag connector 130 has a third channel 131 that communicates with the second channel 121.

[0037] Please refer to Figures 1-3 The working principle of the ostomy bag 100 is as follows:

[0038] The ostomy bag 100 includes a base plate 110, an annular connector 120, and a bag body connector 130. The base plate 110 includes a first channel 111. The annular connector 120 is movably connected to the base plate 110 along the extension direction of the first channel 111. The bag body connector 130 is connected to the annular connector 120. The annular connector 120 has a second channel 121 communicating with the first channel 111, and the bag body connector 130 has a third channel 131 communicating with the second channel 121. This ostomy bag 100 has a simple structure, is easy to use, and can adapt to ostomies of different depths, thereby improving its flexibility of use, improving the fit of installation, and ultimately improving its quality of use.

[0039] The excrement can be discharged into the collection bag through the first channel 111, the second channel 121 and the third channel 131. It should be noted that the bag body connector 130 can be integrated with the collection bag, or it can be a separate part that is assembled and connected during use.

[0040] It should be noted that, in this embodiment, during installation and use, the end of the chassis 110 facing the stoma can be configured as an arc-shaped surface 124 so that it fits with the recess of the stoma. Alternatively, when one end of the annular connector 120 protrudes from the chassis 110 and fits with the stoma, its end can be configured as an arc-shaped surface 124 so that it fits with the recess of the stoma.

[0041] During use, the aforementioned structural design allows the annular connector 120 to be adjusted in position, enabling it to move relative to the chassis 110. This allows its end to displace along the axis of the first channel 111, moving relative to the stoma to accommodate stomas of varying depths. This design enhances both the flexibility of use and the fit with the stoma, thus improving overall quality. Furthermore, when adjustments are made, particularly when increasing the stoma depth and causing the annular connector 120 to move towards a recessed area, one end of the annular connector 120 engages with the recessed area of ​​the stoma.

[0042] Specifically, to allow the annular connector 120 to move, the inner wall of the first channel 111 is provided with an internal thread, and the outer periphery of the annular connector 120 is provided with an external thread that connects with the internal thread. Thus, by rotating, it can be moved relative to the chassis 110.

[0043] Please refer to Figures 1-3 Furthermore, when configuring the annular connector 120, the annular connector 120 includes a first end 122 and a second end 123, which are located on opposite sides of the chassis 110. The outer periphery of the first end 122 is provided with an arc-shaped surface 124, and the second end 123 is provided with a limiting platform 125 for abutting against the chassis 110. In this way, the arc-shaped surface 124 can be configured to fit with the recess at the stoma, while the limiting platform 125 can abut against the chassis 110, thereby limiting its travel.

[0044] To facilitate the replacement of the collection bag, the bag body connector 130 and the annular connector 120 are detachably connected. There are several ways to detachably connect the bag body connector 130 and the annular connector 120; please refer to [the relevant documentation]. Figures 1-5 In this embodiment, the limiting platform 125 is provided with a first snap-fit ​​part 126 on its outer periphery, and the bag body connector 130 is provided with a second snap-fit ​​part 132 at one end for connecting with the annular connector 120. The first snap-fit ​​part 126 is used to engage with the second snap-fit ​​part 132.

[0045] Specifically, the first locking part 126 includes a plurality of limiting pins spaced apart around the axis of the second channel 121, and the second locking part 132 includes a plurality of limiting slots spaced apart around the axis of the second channel 121; each limiting pin is used to engage with a corresponding limiting slot.

[0046] Furthermore, based on the above structure, to facilitate the connection between the bag body connector 130 and the annular connector 120, and to allow the limiting pin to engage in the limiting slot, an arc-shaped bevel is provided at one end of the second channel 121 facing the annular connector 120. This arc-shaped bevel allows the bag body connector 130 to move relative to the annular connector 120 along the axial direction of the second channel 121 in the insertion direction when the bag body connector 130 is connected to the annular connector 120. At this time, the arc-shaped bevel can press the limiting pin into its bottom. When the bag body connector 130 moves to the end of its stroke relative to the annular connector 120 along the axial direction of the second channel 121, it can rotate relative to the annular connector 120, causing the limiting pin to engage in the limiting slot, thus completing the installation. At this point, the engagement of the limiting pin and the limiting slot restricts the movement of both components in the direction of disengagement.

[0047] When it is necessary to detach it, the bag body connector 130 needs to rotate relative to the annular connector 120, so that the limiting pin and the limiting slot are disengaged, thereby enabling the two to be separated quickly.

[0048] To improve the sealing of each connection, at least one first seal is provided at the connection between the annular connector 120 and the chassis 110, and at least one second seal is provided at the connection between the bag body connector 130 and the annular connector 120.

[0049] Based on the above structure, to avoid reflux or inconvenience in drainage during different patient positions, please refer to... Figures 1-6 The ostomy bag 100 also includes a rotating connector 140 connected to the bag body connector 130. Specifically, the rotating connector 140 includes a connecting plate 141 and a rotating head 142. The connecting plate 141 is connected to the bag body connector 130, and the connector head is rotatably connected to the connecting plate 141.

[0050] Therefore, by rotating the rotating head 142 relative to the connecting plate 141, its position can be adjusted. Furthermore, by rotating both of them, the flow direction can always be maintained from the first channel 111 to the third channel 131, thereby avoiding backflow.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
