Barium meal with pneumatosis shadow radiography function and preparation method thereof

Abstract

The invention relates to the technical field of medical materials and in particular to a barium meal with a pneumatosis shadow radiography function and a preparation method thereof. A formula of a medical cleaning agent comprises the following raw materials in parts by weight: aerogenesis powder, agar, a chelator, sodium alginate, gelatin, starch, barium sulfate, absolute ethyl alcohol, and a suitable amount of deionized water. The prepared barium meal adopts a layered particle design. Usual barium meal fluid is converted to the solid barium meal, and a sugar coating on the outermost layer canprevent the barium meal from being affected with damp so as to lose efficacy; the secondary outer layer is prepared from the aerogenesis powder, the agar and the gelatin, after the barium meal is swallowed, a lot of CO2 can be generated in a stomach, so that the stomach is swelled; the next layer is a barium meal layer, the barium sulfate forms a radiography layer in the stomach, and the residualaerogenesis powder also provides the pneumatosis shadow radiography, so the radiography quality is improved; and the final layer is a core of the chelator, the chelator containing a lot of cellulosecan promote gastrointestinal motility, and the barium meal is accelerated to be excreted to the outside of a body.

Description

[0001] This application is a divisional application of an invention patent application titled: A barium meal with air shadow contrast function and its preparation method, application date: April 26, 2018, and application number: 2018103884500. technical field [0002] The invention relates to the technical field of medical materials, in particular to a barium meal with air shadow contrast function and a preparation method thereof. Background technique [0003] Gastrointestinal barium meal examination includes esophagus, stomach, duodenum, small intestine and right colon. During X-ray examination, due to the different density and thickness of various organs and tissues in the human body, it shows a natural level contrast of black and white, but in some parts of the human body, especially the abdomen, because the density of several internal organs and tissues is roughly the same Similarly, it is necessary to use a harmless contrast agent (such as medical barium sulfate) to art...

Problems solved by technology

[0005] However, in this invention, the stomach needs to be dilated before eating the barium meal, and the barium meal can only be swallowed after the stomach expands to a certain extent. There are many types of medicines, which need to be stored separately, so it is very inconvenient to use, and it cannot be quickly eliminated from the body after eating a barium meal, which is easy to cause physical and psychological burden on the patient.
