At one end of the plate 340, the screw plate 341 can be engaged with, in an emergency lowering state, the connecting bolt 332 at one end of the arc-shaped groove 312 near the brake plate 340. A rapid lowering of the rack 320 can be achieved by changing the position of the connecting bolt 332.

In some embodiments, the support base 330 further includes a cam 333 disposed behind the support base 330 and a rotating handle 334 fixed to the cam 333, and the position of the connection bolt 332 is changed by the rotation of the cam 333. When the turning knob 334 is in a horizontal state, the support base 330, the brake plate 340, and the like are pushed in a direction away from the support tube 310, thereby achieving rapid lowering of the rack 320.

In some embodiments, the wound irrigation bed further includes a plurality of baffles 400 respectively disposed on two opposite sides of the bed body 100 in the width direction, the side walls of the bed body 100 are provided with a containing groove 130 capable of containing the top opening of the baffles 400, the two opposite side walls of the containing groove 130 are sequentially provided with a plurality of wedge-shaped grooves 140 with bottom surfaces gradually approaching the inside of the containing groove 130 from bottom to top along the depth direction, and of course, the plurality of wedge-shaped blocks can also be sequentially adjacent, and the top surfaces of the wedge-shaped blocks are horizontal surfaces;
