Abstract
The utility model relates to a filter which is used for filtering and separating cells in a smearing technique of fluid medium thin layer cells, and the filter is composed of a hollow filtering tray and a filtering test tube which has screw threads installed on the tray. A filtering film is tensioned on the tube wall on the lower part of the filtering test tube, and another filtering film is arranged between the filtering tray and the filtering test tube. In practical application, the filter is assembled on a smearing device of the fluid medium thin layer cells by using a positive pressure cell filtering and transferring technique; cell fragments, mucus, and other factors influencing diagnosis can be separated directly under the action of compressed air of a compression cylinder as filtering, without requirement of centrifugal subsidence; the utility model has the advantages of simple operation and low material cost.
Description
Affiliated technical field
The utility model belongs to biomedicine experiment device technology field, relates to a kind of cell filtration and filtrator that separates of being used in liquid based thin-layer cell tabletting technology.
Background technology
The present known Thinprep that is used in
The cell specimen filtrator of liquid based thin-layer cell tabletting technology mainly contains Gyn TransCyt
With Non-Gyn TransCyt
Two types of devices, they all adopt the negative pressure filtration technology, are made up of filter membrane and plastic tube.Owing to be the device that adopts the negative pressure filtration cell technology, need cell specimen must be earlier before filtration through the factor of influence diagnosis such as centrifugation isolated cell fragment, mucus, and then filtration, smear, operation steps complexity, the material cost height is not suitable for large tracts of land and promotes.
The utility model content
The purpose of this utility model is the problem that prior art exists is solved, provide a kind of rational in infrastructure, easy and simple to handle, can reduce cell specimen film-making cost and be suitable for the liquid based thin-layer cell sample filtering device of promoting the use of.
The technical solution that adopts is so for achieving the above object: the liquid based thin-layer cell sample filtering device that is provided is a kind of filter element that adopts the barotropic filtered cell transfer techniques, it is made of the filtration test tube that a hollow filtration pallet and screw thread are contained on the pallet, be provided with one deck filtering membrane filtering to open on the bottom tube wall of test tube, filtering pallet and filtering that pressure is provided with another layer filtering membrane between the test tube.In the practical application, this filtrator is provided on the liquid based thin-layer cell production facility that adopts the barotropic filtered cell transfer techniques, during filtration under the effect of compression cylinder pressurized air, directly isolated cell fragment, mucus etc. influence the factor of diagnosis, must centrifugation, simple to operate, lower cost for material, suitable large tracts of land is promoted.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is used for the work structuring synoptic diagram of liquid based thin-layer cell pelletizer for this filtrator.
Embodiment
Referring to accompanying drawing 1, liquid based thin-layer cell sample filtering device described in the utility model is made up of hollow filtration pallet 1, filtration test tube 2 and filtering membrane 3,4 etc., hollow filtration pallet 1 and filter test tube 2 and be connected by screw thread, one deck in the two-layer filtering membrane 3,4 (filtering membrane 3 of Fig. 1) is located at test tube 2 tube chamber bottoms, and another layer filtering membrane 4 is pressed on and filters between pallet 1 and the filtration test tube 2.
The real work structure of filtrator described in the utility model as shown in Figure 2, this accompanying drawing is the structural representation of the liquid based thin-layer cell pelletizer of employing barotropic filtered cell transfer techniques, number in the figure 5 is a motor, 6 is piston cylinder, 7 for carrying the glass piece, and 8 are the leakage groove, and 9 is guide rail, 10 is slide block, and 11 is support.Guide rail 9 is located on the support 11, and piston cylinder 6 is installed on the guide rail by slide block, can move up and down along guide rail; Motor rotation axis bar lower end is connected with the piston rod thread of piston cylinder 6; Cell filter is located at piston cylinder 6 lower ends, is placed with leakage groove 8 under the cell filter.During work, provide thrust by motor 5, the piston rod of the downward pushing piston cylinder 6 of its rotating shaft rod makes that piston cylinder is descending to be docked with filtrator, produces pressurized air, forms barotropic filtered cell, and the transitional cell smear.
