Abstract
The utility model provides a stool sample device, its characterized in that: include take a sample stick and upper portion open -ended storage bottle, the sample stick includes sleeve pipe and push -and -pull rod, and push -and -pull rod one end stretches into overlaps intraductally and be equipped with spiral sampling probe, and the push -and -pull rod middle part is equipped with the piston with bushing, is equipped with first baffler on the sleeve pipe, and the diameter of first baffler is greater than storage bottle upper portion open -ended diameter, is equipped with the second baffler on the push -and -pull rod, and the diameter of second baffler is greater than the sheathed tube internal diameter. The utility model discloses releasing the sleeve with the push -and -pull rod when stool sample device uses, using the sample of spiral sampling probe, sampling precision is high, the sample back is intraductal with spiral sampling probe withdrawal cover, puts into storage bottle, and the storage of being convenient for, transportation and category tags effectively avoid cross contamination.
Description
Technical field
This utility model relates to a kind of medical test device, specifically, relates to a kind of stool sampling device.
Background technology
Feces detection is one of routine clinical laboratory examination project.By various molecular marker patient DNA, RNA, miRNA, metabolite molecule and the low-abundance protein etc. in human faecal mass are detected, can relatively be visually known some pathological phenomenons of gastrointestinal tract, indirectly judge the function status of digestive tract, pancreas, liver and gall.
At present, common feces detection is typically with catcher and collects sub-fraction sample from the feces of patient and detect.But, because there is no fixing placement place after sampler detection, easily polluted by other article, to each other can cross-contamination, affect testing result.
Utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, it is provided that a kind of stool sampling device storing classifiedly, being difficult to cross infection.
The technical solution of the utility model is:
Stool sampling device, it is characterized in that: include the storage bottle of sampling rod and upper opening, sampling rod includes sleeve pipe and push-pull bar, push-pull bar one end is stretched in sleeve pipe and is provided with spiral sampling head, being provided with in the middle part of push-pull bar and telescopic joint piston, sleeve pipe is provided with the first baffler, and the diameter of the first baffler is more than the diameter of storage bottle upper opening, push-pull bar is provided with the second baffler, and the diameter of the second baffler is more than the internal diameter of sleeve pipe.
A kind of concrete prioritization scheme, storage bottle includes that bottle cap and bottle, bottle cap and bottle are threaded.
A kind of concrete prioritization scheme, sleeve pipe coincide with storage bottle and is connected.
Its excess in air can be avoided to drop.
A kind of concrete prioritization scheme, sleeve pipe is provided with the rubber ring matched with storage bottle.
Avoid sampling thing odor dispersion.
A kind of concrete prioritization scheme, the medial surface of spiral sampling head is arc surface, and its tangent plane is 30 °-80 ° with the angle of push-pull bar axis.
A kind of concrete prioritization scheme, the edge of spiral sampling head is provided with rounding.
Push-pull bar being released when this utility model stool sampling device uses sleeve, uses the sampling of spiral sampling head, sampling precision is high, after sampling, by spiral sampling head retraction sleeve pipe, inserts in storage bottle, it is simple to store, transport and tag along sort, be prevented effectively from cross-contamination.
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model stool sampling device；
Fig. 2 is the structural representation of sampling rod；
Fig. 3 is the structural representation of storage bottle.
