Abstract
The utility model discloses a cell filter which is a device for filtering and transferring cell in fluid. The cell filter comprises a filter film 1 and a cylindrical hollow pipe supporting bracket 2 while the filter film 1 is conglutinated at one end of the hollow pipe supporting bracket 2 and the other end of the hollow pipe supporting bracket is open. A film hole 3 is arranged on the filter film 1. The cell filter film 1 is a polypropylene fiber microporous filter film or a mixed fiber resin microporous filter film. The cylindrical hollow pipe supporting bracket is injection molded with polypropylene material. By connecting the opening of the utility model with a device which has a negative pressure sealing device and disposing the filter film part in the sample liquid, under a certain force of negative pressure, the cell in the sample liquid is absorbed on the surface of the filter film to transfer the cell.
Description
Technical field
The utility model belongs to a kind of separator, is specifically related to the cell filter of cell filtration and transfer.
Background technology
Traditional cervical cell film-making can not be removed impurity in the sample, mucus, blood etc. effectively, causes that the smear cell accumulation is overlapping, blurred background, cellular morphology is unclear even distortion, and influence is diagnosis correctly.Traditional still residual cells more than 80% such as the employed Uterine neck bush of cervical cell film-making, scraper plate or cotton swab can not be transferred to slide and be dropped, and therefore, traditional cervical cell plate coating checking has higher false negative (5%--60%) and false positive.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of cell filter that is used for cell filtration and transfer.
The technical scheme that its technical problem that solves the utility model adopts is: this cell filter mainly is made up of filter membrane and the holder of blank pipe frame, and filter membrane is bonded in an end of blank pipe frame holder, the other end opening of blank pipe frame holder.
Have fenestra on the described filter membrane.
Described filter membrane is a kind of polypropylene fibre miillpore filter, is circle, and diameter is 25 millimeters, and thickness is 6～8 microns.
Described filter membrane is a kind of composite fibre resin miillpore filter, is circle, and diameter is 25 millimeters, and thickness is 6～8 microns.
Described film hole diameter is 5～10 microns, and 70000～100000 fenestras are arranged on every square centimeter of filter membrane.
The holder of described blank pipe frame is cylindrical, adopts polypropylene material injection molded, and internal diameter is 20 millimeters, and external diameter is 25 millimeters, and length is 55 millimeters.
The beneficial effects of the utility model are: earlier with Uterine neck bush, the sample that scraper plate or cotton swab obtain is scrubbed in preserving the liquid bottle, guarantee that the cell more than 95% is washed in the preservation liquid, utilize cell filter to rotate at a high speed then and with preserve the liquid strong collision, produce the eddy current stirring action, cause mucus and the cell mass of preserving liquid to disperse rapidly, attraction by negative pressure, cell is adsorbed on the filter membrane, transfer on the slide at last, because trickle fenestra has filtered bacterial micro-organism, cell evenly is attached to the surface of film, so the smear of making is through artificially colored, it is clear to show as background, the thin-layer cell that cellular morphology is complete has improved greatly and has read sheet effect and correct diagnosis.
