Description

Disposable stool quantitative collection, pretreater

Technical field

The utility model belongs to the medical test utensil, is specifically related to a kind of disposable stool quantitative collection, pretreater.

Background technology

Medically chemically examining stool and urine is a kind of conventional sense project.Sampling method has direct smear microscopy method, leave and take the fresh stool of soya bean size with sampling rod (cotton swab etc.), put into the container with lid of drying, cleaning, censorship, naked eyes Direct observation stool proterties comprises color, hardness etc., and adding physiological saline 1-2 on clean slide drips, the doubtful undesired position of stool direct smear, microscopy are looked in choosing.Existing in the market disposable stool sampler, its advantage is to take a sample conveniently, can transport by cleanliness without any pollution, but the subject matter that exists is that sampling amount is random, in time, lacked for a long time, causes same sample final test results possibility difference huge, and the result can not repeat, can not recognize each other, the dropping liquid osculum is blocked up by the impurity of sample easily, can not squeeze sample, and the too many unfavorable microscopy of impurity in the sample.

The utility model content

The purpose of this utility model provides and a kind ofly takes a sample conveniently, the transportation cleanliness without any pollution, can quantitative sampling disposable stool quantitative collection, pretreater.

The technical scheme that realizes the utility model purpose is: disposable stool quantitative collector comprises the sampling rod assembly and the sample processing tube component of plastics; Described sampling rod assembly is by thief rod, quantitatively restriction is overlapped, moving sample piston and top cover forms, thief rod comprises a hollow tube body, the front end edge of body axially has first breach and forms sampling groove, the front bulkhead of sampling groove is a thin-wall construction, the sample piston that moves of band push rod places in the body, quantitatively the restriction condom is combined on the body, quantitatively the leading section of restriction cover is corresponding with first breach on the body has second breach and forms stopper slot with the sampling groove fit, quantitatively restriction puts and is positioned at the second breach rear end and is provided with and stretches into body and will move the spacing thin-walled stops of sample piston, and the back end periphery of body is provided with connecting portion; Sample processing tube component is made up of the sample accommodating pipe in a band hole and the lower seal cap that is enclosed within on the sample accommodating pipe, fills dilution in the sample accommodating pipe; Thief rod is connected in one by connecting portion and top cover and the sample accommodating pipe that covering moves the sample piston push rod.

Be provided with metal filter screen in the described sample accommodating pipe.

The bottom interior wall of described lower seal cap is provided with the projection of dripping hole plug on the sample accommodating pipe.

Adopt instant-plugging to connect between the connecting portion of described top cover and thief rod, between the connecting portion of sample accommodating pipe and thief rod and adopt between lower seal cap and the sample accommodating pipe and be threaded.

The sampling groove of its thief rod front end of the utility model is used to gather just sample; quantitatively the restriction cover is when the thief rod sinciput; the front end thin-walled of its stopper slot will rupture with the thin-walled stops that is positioned at the second breach rear end; can guarantee that the just sample in the sampling groove has identical amount on the thief rod; the thief rod that will remove after quantitative restriction is overlapped places in the sample accommodating pipe; this moment, piston was not subjected to quantitatively restriction to put the thin-walled stops to limit; just sample in the sampling groove on the thief rod can be clamp-oned in the dilution in the sample accommodating pipe; simultaneously sampling groove front end thin-walled is squeezed off; just impurity in the sample and sampling groove front end thin-walled are by the metal filtration net filtration; can prevent to stop up the dropping liquid aperture; the lower seal cap can guarantee a hole sealing of sample accommodating pipe cleanliness without any pollution when transportation; top cover is used to protect piston push rod not to be damaged, and prevents from simultaneously before use piston push rod to be depressed.

Adopt the beneficial effects of the utility model of said structure, the one, the collection that can make stool quantitatively and certainty ratio dilution mixing, and sample residue filtering can repeat the stool routine examination check result, the problem of solution stool routine examination standardized testing.Two persons of being to use are easy to use; The medical worker is simple to operation, transports safety, satisfies biological protection requirement (free from environmental pollution).

Further specify the technical solution of the utility model below in conjunction with accompanying drawing.

Embodiment

See Fig. 1, disposable stool quantitative collector comprises the sampling rod assembly and the sample processing tube component of plastics; Described sampling rod assembly is by thief rod, quantitatively the restriction cover 6, move sample piston and top cover 1 composition, thief rod comprises a hollow tube body 5, the front end edge of body 5 axially has first breach 13 and forms sampling groove 11, the front bulkhead 14 of sampling groove 11 is a thin-wall construction, moving the sample piston places in the body 5, move the sample piston and comprise piston head 9, connect the push rod 7 of piston head 9 and be located at push rod 7 tail end pressure handles 2, quantitatively restriction cover 6 is linked on the body 5, quantitatively first breach 13 on the leading section of restriction cover 6 and the body 5 is corresponding has second breach 12 and forms and the stopper slot of sampling groove 11 fits, the front bulkhead 15 of stopper slot is spacing with the front end of sampling groove 11, quantitatively be positioned at second breach, 12 rear end on the restriction cover 6 and be provided with and stretch into the body 5 thin-walled stops 10 that piston head 9 is spacing, the back end periphery of body 5 is provided with connecting portion 3; Sample processing tube component drips the sample accommodating pipe 8 in hole by band and the lower seal cap 18 that is enclosed within on the sample accommodating pipe 8 is formed, and is provided with metal filter screen 16 in the sample accommodating pipe 8 and fills dilution 20, and the taper in hole is dripped in the bottom 17 of sample accommodating pipe 8 for band; Thief rod is connected in one by connecting portion 3 and the top cover 1 and the sample accommodating pipe 8 that hide piston push rod 7 tail end pressure handles 2, wherein adopt instant-plugging to connect between the connecting portion 3 of top cover 1 and thief rod, adopt screw thread 4 to be connected between the connecting portion 3 of sample accommodating pipe 8 and thief rod and between lower seal cap 18 and the sample accommodating pipe 8, the bottom interior wall of lower seal cap 18 is provided with the projection 19 with the hole plug on the sample accommodating pipe.
