近年来国内对胃肠道造影多采用双重对比造影术,从而大大提高了诊断率及早期癌症诊断。为使胃壁得到充分扩张便于对细小病变观察,造影中还需加入一定量产气剂。在放射科协助下我们筛选研制成功一种体融性产气剂。这种产气剂的应用,简化了造影中的操作程序,服用时无异臭,无刺激性,病人易于接受,同时具有服后产气快,贮存勿须防潮,对造影无干扰等优点。体融性产气剂所选用的包膜材料具有疏水性,
In recent years, the domestic use of gastrointestinal contrast double contrast contrast imaging, which greatly increased the diagnostic rate and early diagnosis of cancer. In order to make the stomach wall fully expanded to facilitate the observation of small lesions, angiography need to add a certain amount of gas production agent. With the help of radiology, we screened and successfully developed a body fluidity gas generating agent. The application of the gas generating agent simplifies the operating procedures of the contrast imaging. When taken, the method has the advantages of no odor, no irritation and easy patient acceptance. The utility model also has the advantages of quick gas generation after service, moisture proofing without storage, no interference to the angiography, and the like. Body melting gas generating agent selected by the coating material has hydrophobic,
