Capsule type intestinal flora sample segmented collector

Technical Field

The utility model relates to an intestinal flora sampler, in particular to a capsule type intestinal flora sample segmented collector.

Background

A capsule endoscope is an endoscope in the shape of a capsule, which is a medical instrument for examining the intestinal tract of a human body. The capsule endoscope can enter the human body and is used for peeping the health condition of the intestines, stomach and esophagus parts of the human body. Is used for helping doctors diagnose diseases of the digestive tract system of patients. Is an endoscope technology with no pain, no wound and no cross infection.

Faeces are classical samples for studying the intestinal flora, however, we should also appreciate that the flora is not the same in different areas of the gastrointestinal tract. For example, stool samples are not the most reliable samples when studying the flora at different locations in the digestive tract, although it is the most readily available sample in clinical studies. In general, invasive sampling methods such as esophagoscopy, enteroscopy, colonoscopy, or even intestinal flora samples of the corresponding site after intestinal resection are indispensable to achieve sampling of the colonic flora upstream of the stomach, small intestine and rectum. The upstream digestive tract flora specimen is very precious, so that at present, the digestive endoscope is not reasonably used for only intestinal flora sampling, and the digestive endoscope can cause discomfort to a patient; surgical specimens are difficult to obtain and often incorporate perforations, infections, necrosis or tumors, which are detrimental to intestinal flora studies.
