Defecation contrast agent and preparation method thereof

Abstract

The invention provides a defecation contrast agent and a preparation method thereof. The defecation contrast agent comprises the following components in parts by weight: 25 to 30% of II type barium sulfate, 1.5 to 2.5% of sodium hyaluronate, 1.5 to 2.5% of carbomer, 10 to 15% of bletilla striata powder, 0.1 to 0.2% of a humectant, 0.001% to 0.005% of essence and 55 to 60% of a solvent. The defecation contrast agent disclosed by the invention is stable in formula and can be used after being opened, so the use convenience and comfort of medical personnel and patients during defecation contrast examination are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a defecation contrast agent and a preparation method thereof. Background technique [0002] Defecation examination is a new examination method, which is mainly used for clinical symptoms such as difficulty in defecation, chronic constipation, mucus and bloody stools, anal swelling, perineal and lumbosacral pain during defecation, etc. It is difficult for such patients to find problems through clinical digital anal examination, conventional barium enema and endoscopic examination, because the defecation action can not detect abnormalities when the rectum is empty, and abnormalities can only be displayed when the rectum is full and defecated. Inject a special pasty contrast agent into the rectum of the examinee, and observe the anorectum, rectum and pelvic floor statically and dynamically under physiological conditions, and mainly diagnose functional diseases of the anorect...

AI Technical Summary

Problems solved by technology

At present, hospitals generally use type II barium sulfate solution as a contrast agent to simulate normal human stool, but the difference between the contrast agent and normal human stool shape will directly affect the judgment of the test results.

[0003] At present, there is no defecation contrast agent that can be used directly on the market. In the prior art, medical personnel use it after configuring type II barium sulfate and water. The contrast agent has obvious layering and poor patient experience, especially the contrast agent after layering has low viscosity and high fluidity. After being introduced into the patient's rectum, the patient has an unstoppable unpleasant feeling, which is urgently needed in the market. Provide a high-experience defecation imaging product for medical staff and patients
