Disposable enema bags are mainly used for the following groups of people: 1. Constipation patients: For those who have been troubled by constipation for a long time and whose daily diet and oral laxatives are ineffective, they may need to use enemas to stimulate intestinal peristalsis and soften feces, in order to achieve smooth bowel movements. The operation of disposable enema bags is relatively simple, and patients can operate them at home or in medical institutions under the guidance of medical staff, quickly relieving discomfort symptoms. 2. Preoperative bowel preparation for patients: For surgical procedures, especially those related to the intestines, it is necessary to clean the intestines before surgery to prevent contamination of the surgical field of view by intestinal excreta and reduce the risk of postoperative infection. Doctors will arrange for patients to use enema bags before surgery to empty the contents of the intestines and keep them in a relatively "clean" state, ensuring the smooth progress of the surgery. Preoperative preparations for surgeries such as colon cancer and anal fistula involve this process. 3. Colonoscopy examiner: Colonoscopy is an important means of screening and diagnosing intestinal diseases, such as colon cancer and polyps. Before colonoscopy, it is necessary to clean the intestinal tract to present the intestinal wall clearly, which facilitates the doctor's observation of any lesions. Using disposable enema bags for multiple enemas until the discharge is clear like water can achieve the desired intestinal cleansing effect and assist in improving the accuracy of the examination. 4. Patients with anal and rectal diseases: Patients with anal and rectal diseases such as hemorrhoids and anal fissures who experience extremely painful bowel movements. Prolonged retention of feces in the intestine not only exacerbates the pain but also hinders the recovery of the condition. Enema can assist in rapid bowel movements, reduce the pressure of straining during defecation, avoid wound tearing and increased bleeding, and use disposable enema bags flexibly according to needs. 5. Elderly, weak, and long-term bedridden population: Elderly people have weakened intestinal function, slow peristalsis, and are prone to difficulty in defecation; Long term bedridden individuals often face constipation problems due to minimal physical activity and insufficient gastrointestinal motility. The use of disposable enema bags for these two groups of people can help maintain regular bowel movements, prevent complications such as bloating and decreased appetite caused by constipation, and improve quality of life.
