The filtered liquid is discharged to the drainage tube along the liquid collection tank 7 and the drain pipe 5, thereby preventing blood clots, mucus and other wastes in the effusion from clogging the drainage tube;

[0030] The controller 24 periodically controls the start of the first motor 14, which drives the first screw 15 to rotate. The rotation of the first screw 15 drives the sliding plate 17 to move laterally. The second motor 19 is started, and the second motor 19 drives the second screw 20 to rotate. The second screw 20 rotates on the inner wall of the scraper 21 to drive the scraper 21 to move up and down, so that the bottom of the scraper 21 contacts the filter 8. The first motor 14 is controlled to rotate to move the scraper 21 laterally, so that the filtrate on the filter 8 is scraped to the filtrate collecting tank 9, and the filtrate flows along the filtrate collecting tank 9 to the collection bottle 10 for collection.

The scraper 21 can be driven to move horizontally by the transverse movement mechanism, and the filtered material on the filter screen 8 can be scraped to the filtered material collection tank 9 by the telescopic scraping mechanism. The filtered material can be guided to the collection bottle 10 through the filtered material collection tank 9, and the filtered blood clots, mucus and other wastes can be collected by the collection bottle 10. The shell 2 and the filter box 1 can be connected by multiple bolts 11. Together, it is convenient to disassemble and separate the shell body 2 and the filter box 1. The sealing rubber ring 12 can improve the sealing between the shell body 2 and the filter box 1. The first motor 14 drives the first screw 15 to rotate, and the rotation of the first screw 15 drives the sliding plate 17 to move horizontally. The second motor 19 drives the second screw 20 to rotate. The second screw 20 rotates on the inner wall of the scraper 21 to drive the scraper 21 to move up and down. The scraper 21 can be guided and limited by sliding multiple limit blocks 23 on multiple limit grooves 22. The device can be operated and controlled by the controller 24.
