Description
Technical field
The utility model is related to Uterine neck bush fields, specifically cervical cell sampling brush.
Background technology
Uterine neck screening is the abbreviation that TCT is ThinPrep cytologic test, also known as the anti-cancer of cancer screening, uterine neck
It checks.TCT cancer screenings are using liquid-based thin-layer cell detection system detection cervical cell and to carry out TBS cytology specifications
Diagnosis, it is a kind of current cervical cancer cell Examined effect state-of-the-art in the world, with traditional cervical smear Pap smear
It checks compared to the satisfaction and abnormal cervical cell recall rate for significantly improving sample.TCT cancer screenings are thin to cervical carcinoma
The recall rate of born of the same parents is 100%, while can also find precancerous lesion, microorganism infection such as mould, trichomonad, Chlamydia etc..It is checked
Method belongs to woundless testing, and only need to be sloughed side trouser legs by inspection women lies down in examination couch, is taken by health care professional sterile
Vagina and uterine neck are completely exposed vaginal dilator, after sterilizing vagina and uterine neck, with special soft swipe opening of the cervix secretion, are placed in
It is to be detected in special culture solution.General testing result can obtain for 1 to 3 day.
The existing soft brush of sampling is typically all the brush head of mountain row (herringbone), the swipe cell sample under opening of the cervix rotation number
This.Female sex organ has the characteristics that vagina is long, secretion is more, although needing to support vagina using duckbilled device before sampling
It opens, but the both sides of duckbilled device still expose the inner wall of large area, and duckbilled device limited length can not reach opening of the cervix, together
When, since light condition is bad, even if doctor is careful when being sent into sampling brush, still inevitable scratch layers to vaginal wall, operation
Difficulty is big, and the impurity of contamination obscures taken cell sample, influences inspection result.
Utility model content
The purpose of this utility model is to provide cervical cell sampling brush, it can paramedical personnel quickly obtain height
Purity opening of the cervix tissue samples, and operation difficulty is significantly reduced, substantially increase the efficiency and accuracy of inspection.
The utility model to achieve the above object, is achieved through the following technical solutions：
Cervical cell sampling brush, including brush holder support and brush head are covered with the shell of cocoon shape on the outside of the brush head, the shell
Front end is equipped with opening, and the rear end of the shell is equipped with casing, and described sleeve pipe is socketed on brush holder support, the top of the brush holder support and casing
Top be threadedly coupled, the length difference of the brush holder support and casing is more than the length of shell.
The outer wall of the shell is equipped with the bulge loop of annular, and the bulge loop includes being arranged successively from shell nozzle to housing central section
The cross section of the first bulge loop, the second bulge loop and the third bulge loop of row, first bulge loop, the second bulge loop and third bulge loop is radius
Cumulative semicircle successively.
The bristle of the brush head is herringbone bristle.
The end of the brush holder support is equipped with handle, and the handle surface is equipped with the dentation texture of bar shaped.
The bottom end of described sleeve pipe is equipped with the first baffle ring along outer wall side, and the bottom end of described sleeve pipe is cased with plastic hoop, the modeling
Expect that the inner wall of ring is equipped with and is equipped with lid connected to it with matched second baffle ring of the first baffle ring, the rear side of the plastic hoop
Body, lid one end adjacent with plastic hoop are threadedly coupled with the bottom end of casing.
The front side of the shell is equipped with U-shaped notch.
The prior art is compared, the beneficial effects of the utility model are：
1, the original state of the present apparatus is that brush head contracts in shell, while the top screw thread of the top of brush holder support and casing connects
It connects, casing is relatively fixed with brush holder support.After preliminary preparation is ready, it is inserted directly into the shell one end of the present apparatus, when arrival palace
Rotary brush rod after eck makes the threaded engagement of brush holder support and casing unclamp, and promotes brush holder support that brush head is made to be leant out from opening, rotation swipe palace
Tissue on eck, the fully rear post-tensioning brush holder support of swipe make brush head retraction shell, and screwing brush holder support and casing makes the two nose threads sting
It closes, then the present apparatus is taken out and completes sampling.
Sampling is probeed into using the present apparatus, the brush head is before reaching opening of the cervix, including being protected by shell always, if
It probes into and touches vaginal walls on the way, brush head can be isolated with organ surface for the shell, effectively avoid being mixed into it on brush head
His cell impurities ensure that and sample this purity.Operation greatly reduces the difficulty of operation without careful, accelerates
Check speed.
2, first bulge loop, the second bulge loop and third bulge loop form the cyclic annular protuberance of arc around shell, once shell
Encounter vaginal walls, can make have certain distance between shell and inner wall by bulge loop, to make opening not touch inner wall, avoid
Secretion enters from the opening of shell, is further ensured that and samples this purity.
3, on the one hand the setting of the handle facilitates people to be affectedly bashful rotation, on the other hand prevents brush holder support from being slipped from casing, rise
To position-limiting action.
4, the lid is screwed off before use, so that lid is torn with plastic hoop and is detached from.Brush holder support could be operated.Plastics
Ring stays in casing shoe by card, and can not be restored with lid, so as to clearly distinguish whether the present apparatus used, prevents this
Device is by illegal recycling.
