[0027] Specifically, the outer housing 1 is made of a transparent material, the specifications of the first cavity 2 and the second cavity 3 are the same, two inner sleeves 4 are symmetrically arranged, and the inner sleeves 4 are respectively located at the lower ends of the first cavity 2 and the second cavity 3. The advantage is that by loosening the screw cap 5, the alveolar lavage fluid inside the first cavity 2 and the second cavity 3 can be poured out.

[0028] Specifically, two negative pressure tubes 6 are symmetrically arranged, and the negative pressure tubes 6 respectively extend into the first cavity 2 and the second cavity 3. The advantage is that the negative pressure tubes 6 are connected to a vacuum pump to generate negative pressure inside the first cavity 2 and the second cavity 3.

[0029] Embodiment 2:

[0030] As Figures 1-4As shown, it is an improvement over the previous embodiment. Specifically, the drainage tube 7 is a three-way tube, and there are two positioning plates 8 symmetrically arranged. Both ends of the drainage tube 7 pass through the positioning holes 10 and extend into the interiors of the first cavity 2 and the second cavity 3 respectively. The advantage is that the positioning plates 8 support the drainage tube 7. The drainage tube 7 is inserted into the trachea, and the alveolar lavage fluid is inhaled into the first cavity 2 and the second cavity 3 through the drainage tube 7.

[0031] Specifically, there are two lifting plates 11 and adjusting screws 12 symmetrically arranged respectively, and the adjusting screws 12 are parallel to the guide rods 9. The advantage is that the guide rods 9 guide the lifting plates 11. Rotating the adjusting screws 12 drives the lifting plates 11 to move up and down.

[0032] Specifically, the first clamping block 13 is attached to the lower end of the drainage tube 7, and the second clamping block 14 is attached to the upper end of the drainage tube 7.

The guide rod 9 guides the lifting plate 11. The adjusting screw 12 drives the lifting plate 11 to move downward. The second clamping block 14 moves with the lifting plate 11, and one end of the drainage tube 7 is clamped by the first clamping block 13. Then, turn on the vacuum pump to create negative pressure inside the first cavity 2 and the second cavity 3. The first tube absorption liquid is inhaled into the first cavity 2 through the drainage tube 7. After the recovery is completed, rotate the adjusting screw 12 above the first cavity 2 to clamp the drainage tube 7 at the first cavity 2, and rotate the adjusting screw 12 above the second cavity 3 in the reverse direction to loosen the drainage tube 7 at the first cavity 2. Subsequently, the subsequent recovered absorption liquid flows into the second cavity 3 to achieve separate collection of the specimens.
