Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine, in particular to a gastrointestinal tract contrast agent. Background technique [0002] Contrast media is one of the most commonly used drugs in interventional radiology operations, mainly for the display of blood vessels and body cavities. Contrast agents can be divided into two categories, high-density contrast agents with high atomic weight and high specific gravity and low-density contrast agents with low atomic weight and small specific gravity. Commonly used high-density contrast agents are barium sulfate and iodine preparations. Among them, barium sulfate is generally used for gastrointestinal contrast examination, and the pure medical barium sulfate powder is mixed with water to prepare a suspension. The concentration of barium sulfate is usually expressed in weight / volume (W / V), and the concentration of barium sulfate used varies depending on the site and purpose o...

AI Technical Summary

Problems solved by technology

Gastrointestinal radiography filled with barium often conceals small lesions, so oral foaming agents are often used to make both high-density barium and low-density air shadows in the gastrointestinal tract to form gas-barium contrast radiography, but patients generally report Difficulty swallowing and vomiting when swallowing barium

After the examination, it is necessary to drink a lot of water or take laxatives, so as to expel the barium meal as soon as possible, which will bring a burden to the patient's fragile gastrointestinal system and is not conducive to later recovery

Chinese patent 102698296A discloses a gastrointestinal contrast agent, which is composed of heterophylla heterophylla, fried Atractylodes macrocephala, Panax notoginseng, Gastrodia elata, Drynaria fortunei, honeysuckle, Polygonatum odoratum, Tangerine peel, Radix Paeoniae Alba, licorice, honey and barium sulfate. At the same time, it relieves the pain of patients with stomach pain and gastric bleeding, and has a certain nourishing effect on the stomach, but it does not solve the problem of how to promote the barium meal to be discharged after the examination.
