Enter at section or sub- segmental bronchus mouth, then be rapidly injected 3 DEG C of sterile saline by silicone tube, each 20ml-60ml is repeated
4-5 times, negative pressure pumpback immediately is attracted in returnable bottle after perfusion every time, and total resorption yield is 40%-70%, is stayed at present in recycling
It is found during taking, the approach poured into and the approach left and taken are a channel, and the liquid of resorption first, which is likely to be, to be deposited in
Liquid in lavation channel, dilutes sample to a certain extent；Main airway and other leaf section secretion are easy to be mixed into lavation
In liquid, the measurement such as cytology, inflammatory factor is caused to generate error；Can also there is a situation where that irrigating solution is excessive.
Invention content
To overcome the deficiency, device is left and taken the purpose of this utility model is to provide a kind of alveolar wass, lavation and is returned
Pumping approach is different, and can guarantee that irrigating solution is not contaminated, prevents lavation excessive.
Technical solution adopted by the utility model to solve its technical problems is：A kind of alveolar wass leaves and takes device, including
Connector, irrigating tube, suction pipe, the lower end of the connector and being fixedly connected for irrigating tube, connector is equipped with and irrigating tube
The lavation end being connected, irrigating tube are equipped with annular balloon close to lower end outside face, and annular balloon is connected with gas tube, the company
Connector is equipped with resorption end, and resorption end is connected with the upper end of suction pipe, and suction pipe is equipped with resorption close to the side of lower end
Hole.
Further, the suction pipe is located at the inside of irrigating tube, saves space, nor affects on annular balloon normal work,
Ensure the leakproofness of annular balloon.
Further, the gas tube upper end is exposed at lateral surface across connector.
Further, the gas tube upper end is detachably connected with inflator pump, or is detachably connected with syringe.
Further, the lower end of the suction pipe is equipped with and hangs one's head, and can ensure that suction pipe lower end is immersed in irrigating solution, ensures suitable
Sharp resorption irrigating solution.
The utility model has the advantages that：The utility model is simple in structure, and lavation is different with pumpback approach, lavation
Liquid enters alveolar out of irrigating tube, and lavation is carried out to alveolar, and the irrigating solution after lavation enters negative-pressure recovery device by suction pipe,
While resorption, under the action of negative pressure, the irrigating solution in irrigating tube can fully enter alveolar, and the irrigating solution of resorption is then complete
The irrigating solution after alveolar in portion, sampling are more accurate；And energy annular balloon can block the entrance of lavation section, ensure lavation
Liquid is not contaminated, prevents lavation excessive.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sectional view along A-A of the utility model.
1 connector in figure, 2 irrigating tubes, 21 lavation ends, 3 suction pipes, 31 resorption ends, 32 resorption holes, 33 hang one's head, and 4 fill
Tracheae, 41 annular balloons, 42 gas tube upper ends, 43 inflator pumps.
Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.
A kind of alveolar wass as shown in Figure 1 and Figure 2 leaves and takes device, including connector 1, irrigating tube 2, suction pipe 3, described
The lower end of connector 1 is fixedly connected with irrigating tube 2, and connector 1 is equipped with the lavation end 21 being connected with irrigating tube 2, is filled
It washes pipe 2 and is equipped with annular balloon 41 close to lower end outside face, annular balloon 41 is connected with gas tube 4, and the connector 1 is equipped with
Resorption end 31, resorption end 31 are connected with the upper end of suction pipe 3, and suction pipe 3 is equipped with resorption hole close to the side of lower end
32。
Further, the suction pipe 3 is located at the inside of irrigating tube 2, saves space, and it is normal to nor affect on annular balloon 41
Work ensures the leakproofness of annular balloon 41.
Further, the gas tube upper end 42 is exposed at lateral surface across connector.
Further, the gas tube upper end 42 is detachably connected with inflator pump 43, or is detachably connected with syringe, just
In the liquid for injecting air or physiological saline etc into annular balloon 41, annular balloon 41 is made to expand, blocks lesion branch gas
