Description
Technical field
The present invention relates to a kind of cytology DNA to detect Sample preservation liquid pretreatment unit.It is widely used in and falls off carefully
Born of the same parents learn, more particularly to it is a kind of realizes double medium filtration and removal sample in impurity, filter out inflammatory cell, red blood cell, small-sized group
Knit guarantor's storage bottle of cell.It can realize that liquid basal cell is fast and safely effectively filtered and screened, can more effectively be enriched with
The epithelial cell of diagnostic significance improves the slice-making quality of liquid basal cell sample.
Background technology
Cervical carcinoma is multiple one of the malignant tumour of women, cervical carcinoma be can early find, early treatment, can cure one
Kind disease.TCT is mainly used for the screening of cervical carcinoma, and the process of domestic liquid-based cell sample manufacturing is all realized by hand, and what is used is heavy
Drop plate, feed bin safety is poor, needs to overturn when removing liquid in feed bin and topple over, easy cross contamination, and safety is poor.
The screening of cast-off cells includes following operation：It is sampled using sample-taking brush, protects in storage bottle and preserved, vibrated
And it is uniformly dissolved, Thinprep pap test film-making and dye piece, microscopically observation.Flaking method based on manual film-making, including from
Heart sedimentation, membrane type film-making etc., centrifugal settling method are a kind of current medical most commonly used cast-off cells film-makers of testing agency
Method.
The exfoliated cell preservative fluid bottle of centrifugal settling method film-making at present is the plastic bottle of not filter screen mostly, after sampling
Sample-taking brush, which is directly placed into, to be preserved in liquid plastic bottle, and liquid basal cell, which is eluted in, to be preserved in liquid, and impurity and mucus etc. are with cast-off cells
It is attached on glass slide, influences slice-making quality and sees the observation and analytical judgment of piece doctor.
Prefiltration nethike embrane of the present invention can effectively impurity screening and mucus, it is only necessary to which normally oscillation dissolving can be realized, side
Convenient to operate；Synchronous two layers of filtering net film can filter out inflammatory cell, red blood cell, Mini Tissue cell, can more effectively be enriched with
The epithelial cell for having diagnostic significance improves the slice-making quality of liquid basal cell sample, it is ensured that film-making and dye tablet quality.
Invention content
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, a kind of cytology DNA detections Sample preservation liquid pretreatment unit.
More particularly to a kind of guarantor realizing the impurity in double medium filtration and removal sample, inflammatory cell, red blood cell, Mini Tissue cell
Storage bottle.It is made of plastic bottle body, prefiltration net, two layers of filtering net film, bottle cap and suction pipe, the invention major function part is first mistake
Screen membrane and two layers of filtering net film, centre are provided with suction pipe, and the extension position of suction pipe is in the intermediate region of two membranes, prefiltration
Nethike embrane can realize that liquid basal cell is fast and safely effectively filtered and screened, and two layers of filtering net film filter out inflammation with can having handing-over
Cell, red blood cell, Mini Tissue cell, leave useful liquid basal cell, and the outlet of suction pipe is located at useful liquid basal cell region.
The prefiltration screen membrane mesh number 120-150 mesh of the cell-preservation liquid bottle of double film layer functions filters out impurity and glues
Liquid；Two layers of 1000 mesh of filtering net film mesh number, have filtered out inflammatory cell, red blood cell, Mini Tissue cell；Liquid basal cell is carried out
It effectively filters and screens, can more effectively be enriched with the epithelial cell of diagnostic significance, improve the system of liquid basal cell sample
Tablet quality, while ensure that the accuracy of inspection.

Fig. 2 is graphics after plastic bottle body of the present invention is transparent
Fig. 3 is three dimensional sectional view of the present invention
Fig. 4 is front view of the present invention
Fig. 5 is the sectional view of left view of the present invention
Fig. 6 is the sectional view that the present invention looks up direction
1. plastic bottle body；2. two layers of filtering net film；3. prefiltration net；4. bottle cap；5. suction pipe.
Liquid in bottle is divided into three regions：Contain impurity and mucus, the promising useful liquid in middle level in the prefiltration nethike embrane of upper layer
Basal cell contains inflammatory cell, red blood cell, Mini Tissue cell below two layers of filtering net film.
Specific implementation mode
Doctor is sampled using sample-taking brush, sample-taking brush with sample be put into protect storage bottle in preserved, preserve liquid into
Row pretreatment, acquisition have the specimen preserving liquid bottle of cell sample to be transmitted to laboratory, and laboratory operation personnel receive guarantor's storage bottle
When, vibrated and be uniformly dissolved, it is no longer necessary to add separating liquid and cleaning solution, need not be shaken again and centrifuge with it is quiet
It sets, can directly take middle level to there is the epithelial cell of diagnostic significance to carry out Thinprep pap test film-making and dye piece, system is greatly saved
The piece time reduces the labor intensity of manual film-making, improves work efficiency, while better ensuring that the quality control process of sample.
