[0029] When in use, the cart 1 is moved to the dressing change position by using the handle 32, and the universal wheel 10 is locked by its own self-locking mechanism to prevent the cart from moving at will and affecting the dressing change work. The medicines and medical instruments to be used are taken out from the storage drawer 6, the screw 33 is unscrewed out of the screw hole, the two shielding covers 31 are opened, and the medicines and medical instruments are placed on one of the shielding covers 31 located in the pulling direction of the storage drawer 6. The patient places the limbs that need dressing change on the two soft support arms 46 and starts the motor 45. When the motor 45 starts, the dressing change begins. The motor 45 will drive the two reciprocating screws 44 to rotate, so that the two push bars 47 can move back and forth on the reciprocating screws 44. When the push bar 47 moves, it will move a distance in the slot 49. At this time, it will not drive the L-shaped moving seat 48 to move. After moving to one end of the through slot 49, it will continue to move and drive the L-shaped moving seat 48 to move. When moving, the L-shaped moving seat 48 will drive the soft support arm 46 to move, and at the same time drive the gear 411 connected to it to move along the teeth of the rack 412. Under the action of the meshing teeth, the gear 411 drives the soft support arm 46 to rotate, so that the soft support arm 46 rotates and shifts under the limb, so that the soft support arm 46 can regularly change its supporting position on the limb, avoiding the soft support arm 46 from being supported on the same position of the limb for a long time during dressing change, causing poor blood circulation in the patient's limb, causing local congestion, swelling, local tightness, soreness or numbness of the limb, and ensuring the blood circulation of the supported limb and the comfort of the patient.

[0030] When the motor 45 is started, the water pump 414 is turned on at the same time. The water pump 414 delivers the medical disinfectant in the water box 413 to the hose 415 and the bellows 416, and sprays it out through the atomizing nozzle 417. The direction of the atomizing nozzle 417 can be changed by bending the bellows 416. The sprayed atomized disinfectant can reduce the concentration of microorganisms in the air around the wound, thereby reducing the risk of infection, and can help enhance the local sterile environment, provide an additional air disinfection barrier, and help maintain the cleanliness of the environment around the wound, especially in a multi-patient environment or dressing change area, which can effectively prevent the spread of disease.

[0031] According to the location of the wound on the limb, the semicircular support bar 422 can be bent to rotate on the semicircular swing rail 420, thereby driving the atomizing nozzle 417 to change its position around the limb, corresponding to the area where the wound is located, and when the semicircular support bar 422 rotates on the semicircular swing rail 420, the hose 415 will slide in the perforated positioning piece 425 and be stuck in the shielding bar 424, so as to avoid the disorder of the hose 415 affecting the smooth linkage of other structures, and when the semicircular support bar 422 rotates, the elastic positioning ball 421 and the positioning hole 423 are clamped to limit the position of the semicircular support bar 422 and the atomizing nozzle 417, which can be applied to wounds at different locations on the limb. When one of the push bars 47 moves back and forth on the reciprocating screw 44, it will drive the drive shaft 428 above it to move in the auxiliary movement groove 431, so that the sliding plate 430 slides back and forth on the slide rail 427. The sliding of the sliding plate 430 drives the drive frame 433 and the swing shaft 434 to move. The swing shaft 434 moves in the hollow bar 429 and drives the hollow bar 429 to swing back and forth, so that the semicircular swing rail 420 and the arc-shaped connecting bar 419 and the support rail 418 rotate back and forth under the support limit, so that the semicircular support bar 422 drives the atomizing nozzle 417 to swing back and forth at the wound to spray the atomized disinfectant to ensure that the air environment around the wound is disinfected and increase the spray range.

[0032] When the L-shaped moving seat 48 connected to the support rail 418 is driven to move by the push bar 47, the support rail 418 will drive the semicircular swing rail 420, the semicircular support bar 422, the hollow bar 429 and the driving frame 433 to move, and the driving frame 433 will change the connection position above the sliding plate 430 in the connecting groove 432 without affecting the displacement of the sliding plate 430 and the swing of the driving frame 433. By rotating the internal threaded cylinder 52 to move the threaded rod 51 upward, the mounting shell 41 is lifted upward to change the height of the limb support.

[0033] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
