The utility model discloses a negative pressure bottle, filtration membrane pipe, compressor, move the liquid head and have the sealing plug of central through hole, the filtration membrane pipe sets up in the central through hole of sealing plug to with sealing plug in close contact with, the sealing plug sets up the bottleneck department at the negative pressure bottle to with the bottleneck in close contact with of negative pressure bottle the bottom of filtration membrane pipe is provided with the filtration membrane, the negative pressure spout of compressor is connected through the negative pressure port of first takeover with the negative pressure bottle, and the pointed end setting that moves the liquid head is intraductal at the filtration membrane, and the wide mouthful of end that moves the liquid head is connected through the malleation spout of second takeover with the compressor.
Description
Technical field
The utility model belongs to technical field of medical instruments, particularly relates to a kind of filtration unit extracting patient chest ascites cast-off cells.
Background technology
At present, clinical ascites pleural fluid is placed in centrifuge tube, under the effect of 16G centrifugal force, makes the cell precipitation in ascites pleural fluid, abandoning supernatant, the throw out bottom centrifuge tube is collected the extraction realizing cell in ascites pleural fluid.But the existence of high centrifugal force can change the morphological structure of cast-off cells in ascites pleural fluid itself, produce artificial atypia, be difficult to the atypia real with tumour cell and distinguish, increase misdiagnosis rate.And this method wants abandoning supernatant, cell loss residual in supernatant liquor can be made, increase rate of missed diagnosis.
Utility model content
For prior art Problems existing, the utility model provides a kind of filtration unit extracting ascites pleural fluid cast-off cells.This filtration unit filtration membrane filters and replaces centrifugal force to make cell precipitation extract cell, and the cell in ascites pleural fluid is all through molecule filtration membrane, adds the extracted amount of cell, reduces misdiagnosis rate, decrease rate of missed diagnosis.
To achieve these goals, the utility model adopts following technical scheme: a kind of filtration unit extracting ascites pleural fluid cast-off cells, comprises negative pressure bottle, filtration membrane pipe, pneumatic plant, moves liquid head and has the sealing plug of central through hole; Described filtration membrane pipe is arranged in the central through hole of sealing plug, and with sealing plug close contact; Sealing plug is arranged on the bottle mouth position of negative pressure bottle, and with the bottleneck close contact of negative pressure bottle, the bottom of described filtration membrane pipe is provided with filtration membrane; The negative pressure spout of pneumatic plant is connected with the negative port of negative pressure bottle by the first adapter, and the tip moving liquid head is arranged in filtration membrane pipe, and the wide mouth end moving liquid head is connected with the malleation spout of pneumatic plant by the second adapter.
The side edge at the described tip and filtration membrane of moving liquid head is touched.
Described sealing plug adopts round rubber plug.
Described filtration membrane pipe adopts columned plastics tubing.
Described first adapter and the second adapter adopt rubber hose.
Described filtration membrane pipe inserts the length of sealing plug central through hole, is positioned at below sealing plug lower plane 1 centimetre is as the criterion with filtration membrane.
The beneficial effects of the utility model:
The cell adopting filtration unit of the present utility model to extract, because decreasing the generation of artificial atypia not by the effect of centrifugal force, reduces the difficulty that the atypia that really has with tumour cell is distinguished mutually; Add the extracted amount of cell, reduce misdiagnosis rate, decrease rate of missed diagnosis.

In figure: 1-filtration membrane pipe, 2-sealing plug, 3-moves liquid head, and 4-first takes over, the negative pressure spout of 5-pneumatic plant, 6-pneumatic plant, and 7-second takes over, the malleation spout of 8-pneumatic plant, 9-negative pressure bottle.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in FIG. 1 to 3, a kind of filtration unit extracting ascites pleural fluid cast-off cells, comprises negative pressure bottle 9, filtration membrane pipe 1, pneumatic plant 6, moves liquid head 3 and has the sealing plug 2 of central through hole; Described filtration membrane pipe 1 is arranged in the central through hole of sealing plug 2, and with sealing plug 2 close contact; Sealing plug 2 is arranged on the bottle mouth position of negative pressure bottle 9, and with the bottleneck close contact of negative pressure bottle 9, the bottom of described filtration membrane pipe 1 is provided with filtration membrane, and the bottom of filtration membrane pipe 1 is filtered across membrane closure; The negative pressure spout 5 of pneumatic plant is connected with the negative port of negative pressure bottle 9 by the first adapter 4, and the tip moving liquid head 3 is arranged in filtration membrane pipe 1, and the wide mouth end moving liquid head 3 is connected with the malleation spout 8 of pneumatic plant by the second adapter 7.
Described pointed end of moving liquid head 3 tilts to put into filtration membrane pipe 1, touches with the side edge of filtration membrane.
Described sealing plug 2 adopts round rubber plug.
Described filtration membrane pipe 1 adopts columned plastics tubing.
Described first adapter 4 and the second adapter 7 adopt rubber hose.
Described filtration membrane pipe 1 inserts the length of sealing plug 2 central through hole, is positioned at below sealing plug 2 lower plane 1 centimetre is as the criterion with filtration membrane.
Below in conjunction with accompanying drawing, a use procedure of the present utility model is described.
First, connect the power supply of pneumatic plant 6, the ascites pleural fluid handled well is slowly imported in the filtration membrane pipe 1 on negative pressure bottle 9 top in liquid basal cell specimen preserving liquid bottle; By under the filter of filtration membrane mesh under the effect of ascites pleural fluid negative pressure below filtration membrane, instillation negative pressure bottle 9 end, because filtration membrane mesh diameter is less than human body all cells, then the cell residence in ascites pleural fluid is above filtration membrane.Fail to be convened for lack of a quorum from the positive pressure gas moving ejection liquid head 3 and drive the liquid in rotation of filtration membrane top edges, the formed elements being deposited in filtration membrane surface is suspended, make the formed elements leached in the centralized of filtration membrane, avoid the formed elementss such as cell by the clogging of filtration membrane periphery, slow down the filtyration velocity of liquid, be also convenient to liquid filter clean after collecting cell.After liquid has been filtered, the liquid head 3 that moves polluted is taken out, and is separated with the second adapter 7, abandon in contaminated articles refuse bag, take off the sealing plug 2 on negative pressure bottle 9 top, the filtration membrane pipe 1 with filtration membrane is extracted in sealing plug 2, cuts along filtration membrane and filtration membrane pipe 1 joint with knife blade, filtration membrane is taken off, gather up the cell sediment on filtration membrane, with filter paper parcel, conventional dehydration, waxdip, embedding, section; Paraffin section dyeing and immunohistochemical staining.
