In the medical diagnosis and treatment and research process of relevant gynaecopathia, people often need to gather cell at uterus neck, and the Cell sap baseization that collects is made cell smear.At present domestic as yet not development and production go out to be fit to the cervix cells sampler of liquid baseization.Most healthcare givers just carry out cleaning sampling with cotton swab at the cervix uteri place simply.Because the contour structures of cotton swab head does not also meet the anatomic characteristic of cervix uteri, the cotton swab surface area is limited in addition, therefore is difficult to collect simultaneously the cell at three positions of cervix uteri, i.e. the outer mouth cells of neck tube endo cell, zone of transformation cell and cervix uteri, and cell collection is incomplete.On the other hand, with cell transfer when preserving liquid and carrying out the liquid baseization because cotton swab has stronger cell adhesion effect, so the cell on the cotton swab is not easy to be eluted to and preserves in the liquid, causes seriously losing of shifting behind the cell sample.For this reason, some medical research unit is also specially from the cervix cells sampler of external import special use.The short and small taper that the termination of this sampler is made of many settings, dense hair.Because cone is short and small, therefore be difficult to get the neck tube endo cell, and the hair of its setting also damages cervical epithelial tissue easily, in addition, cell is hidden in and also is difficult to eluting in the dense hair, causes losing of shifting behind the cell sample equally.On the other hand, also there is the shortcoming that costs an arm and a leg, is difficult to popularize in the sampler of this import.

Summary of the invention

The purpose of this utility model provide a kind of cell collection comprehensively, gather the back easily with the cervix cells sampler of cell eluting.

This utility model is achieved in that the cervix cells sampler comprises the handle of a strip, handle one end is fixed with sampling head, especially, the flexible fins that sampling head is erect by multi-disc constitutes, each fin is around the axis circumferential array of handle, and the root of fin is gathered in central axis, top with each fin is an envelope, sketch the contours of the revolving body that an anatomical shape with cervix uteri adapts, this revolving body has big two sections of diameter one little, and one section that diameter is little is positioned at front end, is column, can insert in the cervix uteri one section back that is connected in cylinder that diameter is big.During use, the sampling head of handle one end is stretched into vagina, the column of sampling head front end is inserted in the cervix uteri, and make big one section of the diameter of sampling head touch the cervix uteri collar extension, rotate sampling head then, utilize the top of fin to scrape and get cell.Because the revolution shape that the top of each fin is sketched the contours of and the anatomical shape of cervix uteri adapt, therefore sampling head can be scraped the cell at three positions getting cervix uteri simultaneously, wherein being positioned at intracervical column can scrape and get the neck tube endo cell, one section position that is connected mutually that column is big with diameter, can scrape and get the zone of transformation cell that is positioned at neck tube inner membrance and cervix uteri collar extension juncture area, the place ahead end face of one section that diameter is big can be scraped and get the outer mouth cells of cervix uteri, and cell collection is comprehensive.Scrape the cell adhesion got on fin.Compare with cotton swab or dense hair, the effect of sticking between cell and the fin is much smaller, therefore is easy to after the sampling cell eluting from the fin.

The utility model has the advantages that cell collection comprehensively, gather after easily with the cell eluting, with cell transfer when preserving liquid, loss cell is few, helps to improve the accuracy of diagnosis and research.Have again, can be crooked because fin is soft, even therefore the diameter of cervical canal is less, the column part of the sampling head that constitutes with fin still can enter in the cervical canal smoothly.On the other hand, compare with the sampler of import, that this utility model also has is simple in structure, be easy to make, cheap advantage, is easy to apply.

Description of drawings
