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.
