This invention provides an enterostomy protection device, comprising a collection bag, a protective cover, and a buffer assembly. In use, an adhesive plate is attached to the patient's abdominal skin, and the enterostomy passes through a first opening within the collection bag and protective cover. This allows secretions from the enterostomy to flow into the collection bag, facilitating their collection and reducing the risk of infection. The protective cover protects the enterostomy from scratches, pressure, and other damage. When the protective cover is subjected to external force and moves closer to the patient's abdomen, this movement causes a connecting post to move along a guide hole. This movement of the connecting post compresses a limiting plate against a buffer spring, which in turn buffers the force acting on the protective cover. This reduces the force transmitted to the patient's abdomen when the protective cover is subjected to external force, thereby reducing the risk of tearing at the suture between the abdominal wall and intestines and improving the protective effect.
