Capsules for intestine gasgraphy CT detection

Abstract

The invention provides a capsule which is used for the CT examination of intestine air angiography. The capsule is aerogenes drug capsule and muscle loosening drug capsule. An intestinal sol lorica is adopted as a lorica by the aerogenes capsule and citrate acid and sodium bicarbonate are used as the drug core of the capsule. The intestinal sol lorica is adopted as a lorica by the muscle loosening drug capsule and anisodamine is adopted as the drug core of the capsule. The invention is an oral capsule. The lorica is an enteric-coated capsule, resists the acid environment in a stomach, dissolves in the alkaline environment of an intestine and releases the contained drug. The capsule which is used for the CT examination of intestine air angiography has the advantages of reasonable drug configuration, convenient use, stable aerogenesis, no side effect, long service life, good relaxation of the intestinal cavity, good angiography effect and clear image, and is beneficial to the observation of CT inspection on the normal structure and the lesion of the intestine and is provided with good effect in the X ray inspection of gastrointestinal double-contrast barium examination.

Description

technical field [0001] The invention belongs to the field of contrast agent medicine, and more specifically relates to a capsule for small intestine gas contrast CT examination. Background technique [0002] The examination of gastrointestinal diseases mainly uses barium contrast radiography. The traditional X-ray examination of the small intestine is divided into two types, oral barium X-ray enterography and small intestinal gas barium double contrast contrast. The detection agent used is commonly used oral barium. The disadvantages are that it is difficult for the barium to pass through the pylorus, the stomach is dilated, the peristalsis is weak, and there is a large amount of fasting fluid retention. An example of barium being strayed into the trachea too quickly; small intestine gas contrast CT routinely requires oral or intravenous contrast media. In addition to oral contrast media, patients need to fast, which is extremely inconvenient to use. Generally, there are thr...

[0002] The examination of gastrointestinal diseases mainly uses barium contrast radiography. The traditional X-ray examination of the small intestine is divided into two types, oral barium X-ray enterography and small intestinal gas barium double contrast contrast. The detection agent used is commonly used oral barium. The disadvantages are that it is difficult for the barium to pass through the pylorus, the stomach is dilated, the peristalsis is weak, and there is a large amount of fasting fluid retention. An example of barium being strayed into the trachea too quickly; small intestine gas contrast CT routinely requires oral or intravenous contrast media. In addition to oral contrast media, patients need to fast, which is extremely inconvenient to use. Generally, there are three types of oral contrast media: (1 ) High-density contrast agent: 1-2% diatrizoate meglumine is the most widely used contrast agent for ordinary CT scans

This contrast agent can produce good contrast, but the display of the digestive tract wall is not good; (2) Isodensity contrast agent: it is actually drinking water, and the display of the digestive tract wall is better than that of high-density contrast agent, but the morning The contrast difference is small, and it can be used for gastric examination, but the small intestine examination is not satisfactory; (3) low-density contrast agent: it is lipid and gas, and is often used in CT examination of the small intestine. The advantage of this contrast agent is that the wall of the digestive tract can be displayed Satisfactory, but the lipid contrast agent is not easily tolerated by the patient, there are relatively many adverse reactions, and artifacts are likely to occur, so it is rarely used in the examination of the stomach and small intestine
