Embodiment Construction

[0037] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the present invention. examples, but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] combined with Figure 1 to Figure 3 , the present invention is further described:

[0039] An intestinal imaging agent, comprising barium beads 1 , capsule shells 2 and barium powder 3 ; the barium beads 1 and barium powder 3 are arranged in the hollow cavity of the capsule shell 2 .

[0040] Preferably, the capsule shell 2 is a dissolvable hollow shell-like st...

Abstract

The invention provides an intestinal imaging agent and a preparation method thereof. The countable markers (barium rings, barium beads, barium bars, etc.) and a large number of barium-containing particulates are encapsulated in capsules or mixed and then mixed into powders. Patient swallows. The contrast agent first passes through the oral cavity, then enters the small intestine along the digestive tract, and is fully mixed with the food in the small intestine, and then enters the large intestine along with the intestinal contents. Doctors take abdominal X-ray plain films for patients at different time periods. By observing the development of a large number of barium-containing particles, the direction of the patient's intestinal canal can be clearly observed, and then the intestinal location of the marker can be accurately judged to understand the gastrointestinal tract of the marker. Transit time, and its residence time and number in each intestinal segment within a certain period of time, and the excretion rate of markers to guide the type and degree of slow transit patients. In addition, by observing the direction of the intestinal tube, it can assist the doctor to determine whether the patient is suffering from slow colonic transit caused by factors such as long colon and compensatory expansion, which is convenient for the doctor to further diagnose and treat.

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] In the clinical diagnosis of chronic constipation, colonic transit test is usually required for slow transit constipation, and the commonly used imaging products are opaque metal pellets, barium rings or barium strips. Since the imaging product is opaque, when it enters the intestine, it can be observed by X-ray imaging, calculate the number of opaque globules in different quadrants, estimate the percentage of globules in the possible intestinal canal, and speculate whether the possible intestinal canal exists. Colonic slow transit phenomenon. However, the lengthy bowel can cause changes in the position of the bowel, which is very likely to cause difficulty in positioning and cause misdiagnosis; in addition, it is not accurate to judge the bowel only by the quadrant where t...
