Description
This case is divisional application, original application it is entitled：A kind of intestinal contents target component extraction element, former Shen
The applying date please is：2014-09-19, original application application No. is：201410484215.5.
Technical field
The present invention relates to a kind of medical extraction element more particularly to a kind of intestinal contents component extractings.
Background technique
Human gastrointestinal tract content has swill, flora, parasitic ovum etc. are a variety of to have row ingredient, there is intestinal secretion generation
Body fluid components, have because a variety of causes enters foreign matter and liquid in enteron aisle, also by Endoscopic removal but be not easy straight
The tumor tissues fine crushing picked up out.In clinical and research process, the ingredient of these purposes is differentiated and obtain, only relying on has
The instrument of effect assists separation.Flora in normal human's enteron aisle is to have been considered to be a special organ, excrement in human body
Transplanting is considered as a kind of special organ transplant.The bacterium of enteron aisle is about 1000 to 1050 kinds, and the mankind are to wherein big absolutely at present
It organically works between the function and different bacterium of part bacterium according to what mechanism, it is all unclear.Recently, modern doctor
Be becoming increasingly recognized that enteric bacteria in the intracorporal important function of people, will maintain or rebuild the normal bacterium of human body intestinal canal
Critical treatment means of the group as a variety of diseases.Common probiotics drug and food only by one or more of bacteriums of enteron aisle,
By external special culture, then packed according to a certain amount.However, because be included in human body intestinal canal bacterial number with
Type is all very limited, so its therapeutic value is also very limited.Recent years, caprophyl transplanting are gradually paid attention to, especially
It is the infection relevant disease invalid for drug therapies such as common antibiotics, therapeutic value, which seems, especially to be paid attention to, especially
The infection relevant disease invalid for drug therapies such as common antibiotics, therapeutic value is particularly important, for example is treated
Antibiotic-associated diarrhea, intractable inflammatory enteritis, Treatment of Refractory Irritable Bowel Syndrome, immune related intractable diarrhea, obesity,
Food hypersenstivity, depression bowel symptoms, fatty liver etc..
Scientific development so far, although having there is a few studies by colonoscopy, gastroscope nose catheter, jejunum pipe, capsule etc. by excrement
Just suspension or caprophyl suspension are transported in gastrointestinal tract, realize caprophyl transplanting, and still, the caprophyl extraction before transplanting needs elder generation
Excrement is diluted to stool suspension, then suspension is put into filter device again and is filtered, the helminths such as worm's ovum is filtered off, only protects
There are flora, but medical worker when preparing stool suspension either from vision, smell or be psychologically all difficult
Receive, and it is cumbersome, it is desirable to guarantee that the activity of caprophyl must be rapidly completed extraction process, and the extraction element of the prior art
It is difficult to complete within a hour from the extraction for obtaining excrement to caprophyl, it is difficult to ensure that the quality of caprophyl.
