Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments of this utility model. It should be understood that this utility model is not limited to the exemplary embodiments described herein. Based on the embodiments of this utility model described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of this utility model.
[0040] Therefore, in view of the aforementioned technical problems, this utility model proposes a fecal drainage device, such as... Figure 1 As shown. The fecal drainage device includes a bag body 1, a base plate 2, a through hole 3, a connecting pipe 4, a support plate 5, a sewage pipe 6, a flushing pipe 7, and a flushing connector 8.
[0041] The bag body 1 has a base plate 2 on its surface, which is used to adhere to the skin near the anus, thereby fixing the bag body 1 in place near the anus and preventing it from falling off. The base plate 2 has a through hole 3 on its surface, corresponding to the anus, so that when the patient defecates, feces are collected into the bag body 1 through the through hole 3. The base plate 2 adheres to the skin around the anus, fixing the through hole 3 in place at the patient's anus, preventing feces from leaking out of the bag body 1. A connecting tube 4 is provided on the side of the bag body 1 away from the through hole 3, connecting the inside and outside of the bag body 1. A support piece 5 is provided on the direction of the connecting tube 4 towards the bag body 1, located inside the bag body 1 to support the internal space of the bag body 1 and prevent the bag body 1 from sticking together.
[0042] A drain pipe 6 and a flushing pipe 7 are installed on the connecting pipe 4 away from the bag body 1. The drain pipe 6 is connected to an external negative pressure drainage device, which creates negative pressure in the bag body 1, thereby transferring feces to the outside of the bag body 1 through the drainage pipe. The flushing pipe 7 is connected to an external flushing device for flushing the bag body 1. If the feces in the bag body 1 are not completely discharged through the drain pipe 6, the flushing pipe 7 is connected to the external flushing device to flush the bag body 1 to remove all the feces. A flushing connector 8 is located at the end of the flushing pipe 7 away from the connecting pipe 4 to connect the flushing pipe 7 and the external flushing device, providing the water source required for flushing. The flushing device provides the water source required for flushing, which is transmitted to the bag body 1 through the flushing pipe 7 to flush away the remaining feces in the bag body 1, thereby removing all the feces from the bag body 1 and preventing the drain pipe 6 or the connecting pipe 4 from becoming clogged with feces.
[0043] In one embodiment, the length of the support piece 5 extending into the bag body 1 is less than the minimum distance between the connecting tube 4 and the through hole 3, preventing the support piece 5 from obstructing the entry of feces into the through hole 3. The width of the support piece 5 is less than the width of the connecting tube 4 near the bag body 1, and the thickness of the support piece 5 is less than the thickness of the connecting tube 4. Because the support piece 5 has a certain volume, there is a certain space inside the bag body 1 near the support piece 5, which has a certain drainage effect on the feces, preventing the bag body 1 from collapsing and the inner wall from sticking together and causing fecal blockage after negative pressure is generated, and facilitating the discharge of feces inside the bag body 1 through the drain pipe 6.
[0044] In one embodiment, the connecting tube 4 is trapezoidal in shape; the width of the connecting tube 4 near the bag body 1 is greater than the width of the connecting tube 4 away from the bag body 1, which is used to drain the feces inside the bag body 1. The connecting tube 4 has a certain space inside and is relatively rigid, and the trapezoidal design facilitates the discharge of feces from the bag body 1 to the outside of the bag body 1.
[0045] In one embodiment, the flushing tube 7 passes through the connecting tube 4 and extends into the bag body 1, and the length of the flushing tube 7 within the bag body 1 is extendable or fixed; or the flushing tube 7 is located on the side of the connecting tube 4 away from the bag body 1 and does not extend into the bag body 1. When the flushing tube 7 passes through the connecting tube 4 and extends into the bag body 1, the anal area can be flushed and medication can be administered through the through hole 3.
[0046] In one embodiment, the drain pipe 6 passes through the connecting pipe 4 and extends into the bag body 1. The length of the drain pipe 6 within the bag body 1 is extendable or fixed; alternatively, the drain pipe 6 is located on the side of the connecting pipe 4 away from the bag body 1 and does not extend into the bag body 1. Exemplarily, the drain pipe 6 has a certain length to facilitate the discharge of feces from the bag body 1 through an external negative pressure drainage device. The end of the drain pipe 6 away from the connecting pipe 4 is connected to the external negative pressure drainage device, which creates negative pressure in the bag body 1, thereby transferring feces through the drain pipe 6 to the outside of the bag body 1.
[0047] In one embodiment, the base 2 is shaped like a four-leaf clover. While a conventional base shape is circular, the four-leaf clover shape allows for better adhesion to the skin near the anus, resulting in better stability. The through-hole 3 is located at the center of the base 2, corresponding to the anus. The base 2 comprises four base plates, with the maximum width of the two plates closer to the connecting tube 4 being greater than the maximum width of the two plates farther from the connecting tube 4, to ensure stable adhesion to the skin near the anus. Exemplarily, the base 2 is bonded and fixed to the bag body 1 near the through-hole 3.
[0048] In one embodiment, the base 2 is a hydrogel dressing to improve patient comfort and facilitate wound healing. A protective film is provided on the surface of the base 2 to protect it; when the protective film is removed, the base 2 adheres to the skin near the anus.
[0049] In one embodiment, the through-hole 3 is elliptical in shape; the connecting tube 4 is located along the major axis of the ellipse. The elliptical shape of the through-hole 3 better accommodates the shape of the anus, and the connecting tube 4 is positioned along the major axis of the ellipse. The sewage pipe 6 connected to the connecting tube 4 is relatively long and requires connection to an external negative pressure drainage device. This design facilitates both the use and replacement of the fecal drainage device by the patient.
[0050] In one embodiment, the bag 1 includes a first surface and a second surface; the first surface includes a first side and a second side, the first side being a non-woven fabric and the second side being a polyester film; the second surface is a polyester film; the base 2 is disposed on the first surface, so that the first surface is close to the anus to improve patient comfort.
[0051] In one embodiment, the device further includes a fixing joint: the fixing joint includes a first fixing joint 9 and a second fixing joint 10; the first fixing joint 9 is disposed at the connection between the sewage pipe 6 and the connecting pipe 4, and is used to connect the sewage pipe 6 and the connecting pipe 4; the second fixing joint 10 is disposed at one end of the sewage pipe 6 away from the connecting pipe 4, and is used to connect the sewage pipe 6 and the external negative pressure drainage device.
[0052] This concludes the introduction to the structure of the fecal drainage device of this utility model. The complete fecal drainage device may also include other components, which will not be described in detail here.
[0053] According to an embodiment of this utility model, the fecal drainage device uses a base to adhere to the skin near the anus, aligning the through-hole with the anus position. When feces are collected into the bag through the through-hole, an external negative pressure drainage device uses negative pressure to discharge the feces out of the bag through a drain pipe, and then flushes away any remaining feces inside the bag through a flushing pipe. A support plate is installed inside the bag to support the internal space, preventing the bag from collapsing and sticking to the inner wall when negative pressure is generated, thus facilitating the discharge of feces from the bag through the drain pipe.
