Inflatable Colorectal Outer Wall Constriction Device

The inflatable colorectal outer wall constriction device, characterized in that it comprises:

• A support rod, a curling balloon airway, a head balloon airway, a curling balloon, and a head balloon. Wherein one end of the support rod is provided with an inflation port, and the other end is successively connected to the curling balloon and the head balloon. During use, the inflation port is located outside the body;
• the inflation port comprises a first inflation port and a second inflation port. The support rod has a hollow conduit, the curling balloon airway and the head balloon airway are located within the hollow conduit, and the first inflation port communicates with the curling balloon through the curling balloon airway, the second inflation port communicates with the head balloon through the head balloon airway. The end of the support rod near the curling balloon is provided with a slot matching the head balloon. When the first inflation port is inflated, the curling balloon can curl into a ring shape, and when the second inflation port is inflated, the head balloon expands, and the expanded head balloon is snapped into the slot, applying a certain constraint to the outer wall of the intestine to ensure a tight seal between the fecal diversion device and the inner wall of the intestine.
