[0002] An ostomy bag is an important medical device designed specifically for patients after an ostomy to collect and store bodily waste, such as urine and feces. An ostomy is a surgical procedure performed to treat a disease by pulling a section of the intestine out of the abdominal cavity and creating an opening in the abdominal wall to allow for the passage of feces. These patients, due to intestinal damage, anal resection, or other reasons, are unable to defecate normally through the anus and therefore require an artificial anal bag to assist with excretion.
[0003] Existing anal bags have only one discharge port, requiring frequent cleaning to ensure their continued use. However, a single discharge port prevents simultaneous discharge and flushing, making internal cleaning difficult. Therefore, we propose a flushable double-port artificial anal bag to address these issues. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) By setting an movable opening on the other side of the bag body inlet direction, a threaded tube is set inside the movable opening, and a water outlet is set on one side of the surface of the threaded tube. A water inlet plate is set at the front end of the threaded tube. Clean water can be introduced into the inside of the threaded tube through the water inlet plate by connecting the water pipe. Clean water enters the inside of the bag body from the water outlet. At the same time, the clamp is loosened to open the drain port, so that water can be flushed and drained at the same time, keeping the inside of the bag body clean. At the same time, the threaded tube can be rotated so that the water outlet can rotate inside the bag body, thereby preventing the water outlet from being fixed and causing dead corners that cannot be flushed. A sealing plate is set at the front end of the water inlet plate. When not flushing, the water inlet plate can be closed by the sealing plate to prevent air or dust from sticking inside the water inlet plate.
[0016] (2) By setting a leak-proof pad at the other end of the threaded tube, the threaded tube is in an extended state when not in use. At this time, the leak-proof pad is attached to the inner wall of the movable port and can seal the movable port. When rinsing is required, the threaded tube is inserted into the bag body and the leak-proof pad is used to block and seal the inlet to prevent water from entering the stoma and body through the inlet during rinsing. At the same time, a threaded movable limit ring is set on the outside of the threaded tube. When not in use, the limit ring is rotated to the outside of the movable port and tightened. At this time, the position of the limit ring is just to seal the outlet. At the same time, the movable port is sealed by the clamping of the leak-proof pad and the limit ring to prevent leakage. When rinsing is required, the limit ring can be rotated to the inside of the water inlet plate, so that the threaded tube can be inserted into the bag body. Attached Figure Description
