Intestinal developing agent and preparation method thereof

Abstract

The invention provides an intestinal developing agent and a preparation method thereof. Countable markers (barium rings, barium beads, barium strips and the like) and a large number of particles containing barium are sealed into capsules or blended to be swallowed by a patient in a form of power. Firstly the developing agent passes through an oral cavity, then enters a small intestine along a digestive tract, and is fully mixed with chyme in the small intestine, and then enters a large intestine with intestinal contents. Doctors take abdominal X-ray plain films for a patient in different periods, by observing the development of the large number of the particles containing the barium, the trend of intestines of the patient is clearly observed, and then the locations of markers in the intestines are accurately determined, thus the transportation time of the markers through the stomach and intestines is understood, and the classification and degree of slow transport patients are guided bythe retention time and the number of intestinal segments in a certain period of time and the discharge rate of the markers. In addition, by observing the trend of the intestines, doctors are helped to judge whether the patient is suffered from colon slow transportation caused by the factors such as dolichocolon and compensatory expansion or not, and further diagnosis and treatment by the doctorsare convenient.

Description

technical field [0001] The invention relates to the technical field of medical imaging agents, in particular to an intestinal imaging agent and a preparation method thereof. Background technique [0002] Clinically, in the diagnosis of chronic constipation, a colonic transit test is usually required for slow transit constipation, and the commonly used imaging products are opaque metal balls, barium rings or barium strips. Because the developed product is opaque, when it enters the intestinal tract, it can be observed after X-ray imaging, the number of opaque globules in different quadrants can be calculated, the percentage of the globules in the possible intestine can be estimated, and whether the possible intestine exists Colonic slow transit phenomenon. However, the lengthy intestinal tube will cause changes in the position of the intestinal tube, which is very easy to cause positioning difficulties and cause misdiagnosis; in addition, it is not accurate to judge the inte...
