Technical Field

[0001] The utility model relates to the technical field of rectal CT examination, in particular to a dilatation device for rectal CT examination. Background Technique

[0002] Rectal CT examination can not only observe whether the intestinal wall is thickened or not, but also observe the conditions of the surrounding tissues outside the intestinal wall. Usually, it is combined with other examination methods such as colonoscopy to comprehensively judge the stage of intestinal tumors, so as to provide better treatment methods for patients. The preparation work of rectal CT is mainly to prepare the intestine, and the quality of the preparation work will directly affect the examination results. Patients must strictly follow the doctor's advice for preparation, requiring patients to have a low-residue diet within three days before the examination, and perform cleansing enema the night before the examination or early in the morning of the examination day to try to drain the intestinal contents as clean as possible.

[0003] Currently, when performing rectal CT examination on patients, it is necessary to inject contrast agent into the inner side of the patient's rectum so that the CT equipment can observe the patient's rectal conditions more accurately. However, currently, when injecting contrast agent into the patient's rectum, it is often directly injected through a syringe inserted into the patient's rectum. After injection, the contrast agent is unevenly distributed, and due to many folds on the inner wall of the patient's rectum, the accumulation of contrast agent is not conducive to CT examination.

[0004] Therefore, a dilatation device for rectal CT examination is needed, which can inject contrast agent evenly and can stably dilate the patient's rectum to facilitate examination. Content of the Utility Model
