At this time, the interior of the through groove 204 is connected to the outside air, and the pressure difference on both sides of the rubber sheet 206 disappears, so that the rubber sheet 206 returns to its original position, and the first spring 215 drives the first tooth plate 207 to move upward, so that the induction switch 216 is activated, so that the flushing liquid enters the inside of the water inlet pipe 203, and under the reverse drive of the first gear 209, the second tooth plate 214 returns to its original position, and the flushing liquid can smoothly enter the inside of the main rod 201.

[0028] When the sixth pulley 404 rotates, it can drive the fifth pulley 403 to rotate, and then drive the third gear 402 to rotate. When the third gear 402 rotates, the rotating third gear 402 can drive the fourth gear 408 to rotate. The rotation of the fourth gear 408 can drive the third threaded rod 407 to move up and down. Before drainage, the staff inserts the third threaded rod 407 into the sliding plate 409. At this time, the sliding plate 409 can drive the mounting bracket 410 to move, so that the mounting bracket 410 can compress the second spring 412. When the third threaded rod 407 moves upward to a certain position, the third threaded rod 407 is separated from the sliding plate 409. The sliding plate 409 returns to its original position under the action of the second spring 412. When the sliding plate 409 is returning to its original position, the sliding plate 409 can slide inside the second sliding groove 414. At the same time, the sliding plate 409 can drive the third tooth plate 415 to move. The movement of the third tooth plate 415 can drive the seventh gear 416 to rotate. The rotation of the seventh gear 416 can drive the fourth threaded rod 417 to move downward, so that the sponge plate 420 can wipe the infected area. After drainage and flushing, flushing fluid, blood, exudate, etc. may remain on the surface of the wound and surrounding skin. Wiping can effectively remove these residual liquids, keep the local skin clean and dry, reduce the breeding ground for bacteria, and reduce the risk of reinfection.
