Description
[technical field]
The utility model is related to medical specimen sample devices technical field, specifically a kind of saliva with filtration
Harvester.
[background technology]
Saliva is a kind of complicated mixture, not only containing various protein, also containing DNA, RNA, aliphatic acid and each
Plant microorganism etc..Research finds that the various protein components in blood are also existed in saliva, and saliva can reflect in blood
The change of various protein levels.Thus it is possible to the diagnosis of disease be carried out by the detection of saliva, with collection blood sample
Condition ratio, saliva collection and saliva detect that simple and convenient, safe and reliable, cost is low and noninvasive, can also be carried out even if staying at home.By
This is visible, and salivary analysis technology avoids the pain of blood sampling and takes the embarrassment of urine, reduces the pressure seen on patient's psychology and body
Power.In addition, sputum test can substantially reduce the incidence of blood-borne diseases.
Current saliva acquisition mode is to utilize cotton swab, filter core or Disposable paper cup, the saliva of these sampling instruments collection
The DNA of 30% microorganism can be mixed with by extracting DNA again, be that postorder sequencing adds cost.
[content of the invention]
The purpose of this utility model is that a kind of structure of design is novel absorbs saliva by polynary ester fiber, and self compaction goes out saliva
With filtering saliva, be easy to gather, collect, filter, sealed saliva collecting device.
To achieve these goals, a kind of saliva collecting device with filtration is designed, it is characterised in that including saliva
Collection tube, polynary ester fiber absorbent tampons, filter membrane, sealing piston, intermediate filtered pipe, press-fit closure and preserve liquid composition, institute
The saliva collection tube stated is the cavity pipe of one end open, and the bottom end sealing piston of intermediate filtered pipe is via insertion saliva at opening
Polynary ester fiber absorbent tampons in liquid collection tube, with saliva collection tube offset, and the intermediate filtered bottom of the tube offers some logical
Hole, and filter membrane is pasted with, intermediate filtered tube top portion, which is provided with, press-fits closure, and is linked with it.
The filter membrane installed in intermediate filtered pipe uses the hydrophylic filter membranes less than 0.45ul.
It is described to press-fit closure and be detachably connected with intermediate filtered tube top portion, press-fit closure self compaction intermediate filtered pipe and
Seal collection tube.
The utility model compared with the existing technology, the advantage is that microbial DNA in saliva using a kind of new method and
Host DNA is separated：Present apparatus sandwich construction, polynary ester fiber absorbent tampons are absorbed after saliva, are placed in collection tube and are not used specially
With centrifuge, saliva can be just collected out with self compaction and by filter membrane, filter out 30% microbial DNA.After filtering
Saliva, which adds preservation liquid, can carry out normal temperature transport and preservation, can be used for DNA detections, reduce sequencing cost.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model；
Fig. 2 is sectional view of the present utility model
Description of symbols in figure
More than 1 yuan of ester fiber absorbent tampons, 2 saliva collection tubes, 3 sealing pistons, 4 filter membranes, 5 intermediate filtered pipes, 6 press-fit it is close
Capping.
[embodiment]
The utility model is described in further detail below in conjunction with the accompanying drawings, the structure and principle of this device people professional to this
For be very clear.It should be appreciated that specific embodiment described herein is only to explain the utility model, and without
In restriction the utility model.
As shown in figure 1, the present apparatus includes saliva collection tube, polynary ester fiber absorbent tampons, filter membrane and sealing piston, centre
Screen pipe and press-fit closure and DNA and preserve liquid composition, described saliva collection tube is the cavity pipe of one end open, intermediate filtered
The bottom end sealing piston of pipe is via the polynary ester fiber absorbent tampons inserted at opening in saliva collection tube, with saliva collection tube
Offset, the intermediate filtered bottom of the tube offers some through holes, and is pasted with filter membrane, and filter membrane is located at piston and intermediate filtered
Between bottom of the tube, intermediate filtered tube top portion, which is provided with, press-fits closure, and is linked with it.
The filter membrane installed in intermediate filtered pipe uses the hydrophylic filter membranes less than 0.45ul.
It is described to press-fit closure and be detachably connected with intermediate filtered tube top portion, press-fit closure self compaction intermediate filtered pipe and
Seal collection tube.Press-fit filtering cover to be directly tightened on saliva collection tube, play sealing function.
Polynary ester fiber absorbent tampons are absorbed after saliva, are placed in collection tube, with assembling sealing piston and filter membrane
Intermediate filtered pipe self compaction collects out saliva and separates microbial DNA and host DNA by filter membrane.Filter membrane is used
The hydrophylic filter membranes that aperture is less than 0.45ul are made.
Microbial DNA in saliva and host DNA are separated using a kind of new method：Present apparatus sandwich construction, polyester is fine
Tie up absorbent tampons to absorb after saliva, be placed in collection tube and do not use special centrifugal machine, saliva can be just collected out simultaneously with self compaction
And by filter membrane, filter out 30% microbial DNA.Saliva, which adds preservation liquid, after filtering can carry out normal temperature transport and guarantor
Deposit, DNA detections can be used for, sequencing cost is reduced.
