Quick-hardening contrast agent special for defecography

Abstract

The invention relates to preparation of a medicine which is specially used for defecography, can be quickly changed from a liquid state to a gel state in the checking process and can be developed under X rays. The medicine is prepared by adding a material with a quick hardening property in the preparation process and water into a contrast agent taking metal salts (such as barium sulfate and the like) which are non-toxic and harmless, are not absorbed by human bodies and are high in atomic numbers as main materials. The formula has a reasonable design, the medicine is economic and practical and does not have any toxic or side effect, the detection result is accurate and reliable, and a favorable basis can be provided for clinical diagnosis and treatment.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation for human body enema examination, and specifically relates to a preparation of a medicine specially used for defecation contrast that can quickly change from a liquid state to a gel state during the inspection process and can be developed under X-rays, and is specially used for human defecation contrast examine. Background technique [0002] Defecography is a new method of examination and is a reliable basis for determining treatment. It is mainly used to diagnose functional diseases of the anorectum, such as rectal mucosal prolapse, rectal intussusception, rectocele and pelvic floor spasm syndrome. The main clinical symptoms of this type of disease are dysfeciatation, chronic constipation, anal bulging, etc., and there are no positive findings through digital anus, rectoscopy and barium enema. This examination was carried out relatively late in China, and the technology is not very...

Problems solved by technology

[0006] However, the real problem is that if the prepared contrast agent has the same concentration as the feces and is in a similar state, it cannot be injected into the intestinal tract

The contrast agent concentration is too low, although it is easy to inject into the intestinal tract, it is difficult to obtain accurate diagnostic conclusions
