Description
Technical field
The present invention relates to a kind of medical collection device, particularly relate to a kind of disposable intestinal contents target component extraction element.
Background technology
Human gastrointestinal tract content has that swill, 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 matter in enteron aisle 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 enteron aisle to be considered in human body a special organ, and ight soil is transplanted and is considered to a kind of special organ transplantation.The bacterium of enteron aisle 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 vital role of intestinal bacteria in human body, will maintain or rebuild the critical treatment means of human intestinal normal microflora as various diseases.Conventional probiotic bacterium medicine and food, just by one or more bacteriums of enteron aisle, through external special cultivation, are then packed according to certain amount.But, because to include the bacteria's numbers and species of human intestinal 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 pharmacological agenies 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 pharmacological agenies 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, dysthymia disorders bowel symptoms, fatty liver etc.
Scientific development so far, although had a few studies by intestines mirror, gastroscope nasogastric tube, jejunum pipe, stool suspension or caprophyl suspension are transported in gi tract by capsules etc., realize caprophyl to transplant, but, all there is such problem in the extracting method before caprophyl transplanting, owing to being substantially in oxygen-free environment in body enteron aisle, namely most caprophyl belongs to anaerobic bacterium, existing extraction equipment is not all for caprophyl provides a kind of oxygen-free environment, if the patent No. is CN201310051614, patent name is: a kind of medical cavity content target component reclaims apparatus, it is injected by malleation, vacuum suction, the modes of action such as gravity are fecal suspension circulation, filtration etc. provides required strength, such extraction element cannot provide oxygen-free environment for caprophyl, cause most of caprophyl dead, be difficult to the high quality ensureing caprophyl sample, reduce the result for the treatment of of caprophyl to some disease.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, can ensure that flora is in oxygen-free environment and improves the disposable intestinal contents target component extraction element of caprophyl specimen quality.
The present invention is realized by following measure: a kind of disposable intestinal contents target component extraction element, comprise extraction tube, described extraction tube comprises only upper end open and the filtering net that is connected with the inner wall sealing of described body with some levels of the body that can seal, described body also comprises and is arranged on fluid injection end on described tube wall and liquid pumping side, described fluid injection end is between upper end open and the described filtering net of the first step, described liquid pumping side is between two adjacent described filtering nets, described filtering net from top to bottom aperture is the trend reduced step by step, described body is soft polymer material.
The quantity of described filtering net is preferably 5-30; Interval is had between filtering net described in adjacent two-stage.
Described sealing can be hot-seal, also directly can be rolled by opening and clamp, ensure that opening seals.
The material of described body is silica gel, soft rubber, PVC or soft plastics, and one-body molded.
The aperture of described filtering net is 0.0004-5.00mm.
Also comprise with described extraction tube with the use of extraction press from both sides, described extraction folder comprises two parallel extrusion rolls, described extrusion roll comprises roll shaft and can along the roller of described roll shaft radial rotary, the two ends of described roll shaft are symmetrically arranged with through hole, and two described extrusion rolls are connected with ears nut by the lead screw through described through hole.
The screw terminal of described lead screw is yi word pattern, is provided with yi word pattern limited impression with on roll shaft described in described screw terminal correspondence position.
Beneficial effect of the present invention is: structure is simple, easy to operate, for caprophyl provides a kind of oxygen-free environment, can ensure the integrity of caprophyl, improves the effect of transplanting caprophyl disease therapy, wherein, during use, the ight soil just obtained is put into extraction tube, rapidly by the opening heated sealant (or using heat sealing machine sealing) of body, syringe is used to find time to body through fluid injection end, and then use syringe to pass fluid injection end in body, inject diluent (as physiological saline or milk etc.), manual squeezing, rub and make ight soil and diluent fully be mixed to get fecal suspension, then folder is extracted by rotating the adjustment of ears nut, make the distance between extrusion roll just or be slightly less than the thickness of body, pull roll shaft from top to bottom, fecal suspension is made step by step through filtering net by the squeeze of two rollers and gravity, because the aperture of filtering net reduces step by step, the material that every one-level filtering net stores is all not identical, every one-level all has liquid pumping side, different target components can be extracted according to demand.
