Description
This case is divisional application, and the denomination of invention of original application is: a kind of intestinal contents target component extraction element, and the applying date of original application is: 2014-09-19, and the application number of original application is: 201410484215.5.
Technical field
The present invention relates to a kind of medical extraction element, particularly relate to a kind of intestinal contents component extracting.
Background technology
Human gastrointestinal tract content has that food debris, flora, parasitic ovum etc. are multiple row composition, there is the body fluid components that intestinal secretion generates, have because a variety of causes enters foreign body in intestinal and liquid, also have by Endoscopic removal but the tumor tissues in small, broken bits of not easily directly taking-up.In clinical and research process, differentiate and obtain the composition of these objects, only have rely on effective apparatus auxiliary separating from.Flora in normal human's intestinal to be considered in human body a special organ, and feces is transplanted and is considered to a kind of special organ transplantation.The antibacterial of intestinal is about 1000 to 1050 kinds, and the current mankind to the function of wherein Most bacterial, and according to what mechanism organically work between different bacterium, all it be unclear that.Recently, modern medicine has more and more recognized the important function of intestinal bacteria in human body, will maintain or rebuild the critical treatment means of human body intestinal canal normal flora as various diseases.Conventional probiotic bacteria medicine and food, just by one or more antibacterials of intestinal, through external special cultivation, are then packed according to certain amount.But, because to include the bacteria's numbers and species of human body intestinal canal in all very limited, so its therapeutic value is also very limited.Recent years, caprophyl is transplanted and is paid attention to gradually, especially for the disease that the infection that the Drug therapys such as common antibiotics are invalid is relevant, its therapeutic value seems and particularly payes attention to, especially for the disease that the infection that the Drug therapys such as common antibiotics are invalid is relevant, its therapeutic value seems particularly important, such as treats antibiotic-associated diarrhea, intractable inflammatory enteritis, Treatment of Refractory Irritable Bowel Syndrome, immunity relevant intractable diarrhoea, obesity, food anaphylaxis, depression bowel symptoms, fatty liver etc.
Scientific development so far, although had a few studies by intestinal mirror, gastroscope nasogastric tube, jejunum pipe, stool suspension or caprophyl suspension are transported in gastrointestinal tract by capsules etc., realize caprophyl to transplant, but, caprophyl before transplanting extracts to be needed first loose and watery stool to be interpreted into stool suspension, and then suspension is put into defecator inner filtration, the parasites such as elimination worm's ovum, the flora only remained with, but no matter medical worker is from vision when preparing stool suspension, olfactory sensation is still psychological all beyond affordability, and complex operation, want to ensure that the activity of caprophyl must complete leaching process fast, and the extraction element of prior art is difficult to complete in one hour from obtaining the extraction of feces to caprophyl, be difficult to the quality guaranteeing caprophyl.
