Description

Technical Field

[0001] The utility model relates to the technical field related to medical instruments, in particular to a retention enema device. Background Art

[0002] The lesions of ulcerative colitis are mainly located in the colon mucosa, often involving the rectum and the entire colon. The main symptoms are abdominal pain, diarrhea, mucus or bloody stools, and systemic symptoms and serious complications. The disease is characterized by a long course and repeated attacks, and there is still a lack of radical treatment methods. Drug retention enema is an effective and long-term repeated method for the treatment of ulcerative colitis in clinical practice. The drug is in direct contact with the lesion site, increasing the bioavailability of the drug and exerting its therapeutic effect. During treatment, an enema device is required.
