[0002] Bone joints are connected by capsules made of connective tissue between adjacent bones. The indirect connection between bones is called bone joints. Bone joint surgery includes common joint incision, reduction and internal fixation, joint cleaning, joint shaping, and joint fusion. After bone joint surgery, it is necessary to change the dressing of the wound at the joint. Wound dressing technology, also known as wound dressing change, is a basic operation technique that surgeons must master and is one of the important contents of surgical treatment. It is also a professional skill that other surgical doctors cannot ignore. The correctness of the dressing method will directly affect the patient's wound healing and recovery. Improper dressing methods will inevitably delay the healing of the wound or cause long-term non-healing, which will cause physical pain to the patient.

[0026] A method for using a portable dressing-changing auxiliary device for bone joints comprises the following steps: Step 1: Push the dressing change device body 1 through the moving wheel 2 to the side where the patient needs to change the dressing; Step 2: Control the placement plate 6 to move downward, fit with the bed, and move it to the bed, then slowly lift the patient's lower limbs onto the support structure 7 and adjust the height; Step 3: According to the position of the lower limb wound, adjust the position and height of the waste liquid box 906 on the collection structure 9; Step 4: According to the position where the medical staff stands, adjust the position of the medicine box 1009 on the storage structure 10. After the adjustment, the dressing change operation can be performed.

[0027] Working principle: When the present invention is used, the dressing change device body 1 is pushed to move to one side of the bed through the bottom moving wheel 2. According to the position of the patient's lower limbs, the first motor 5 is controlled to run. The internal technology of the first motor 5 is the existing technology. After the first motor 5 runs, it drives the first screw rod 3 at the output end to rotate. When the first screw rod 3 rotates, it drives the first threaded sleeve 4 to move downward through the thread, and then drives the placement plate 6 and the support structure 7 to move downward. After moving downward, the medical staff gently lifts the patient's lower limbs and places them on the support structure 7, so that the thigh is placed on the arc plate 711, and the calf is placed on the auxiliary plate 702 and the sponge pad 708. At this time, the gravity of the thigh drives the arc plate 711 to tilt to the left to squeeze the spring 712, so as to adapt to the placement angle of the thigh. At this time, the second motor is controlled 704 is running, and the internal technology of the second motor 704 is the existing technology. After the second motor 704 is running, it drives the second screw rod 703 at the output end to rotate in the moving groove, and drives the two second threaded sleeves 705 to move inward at the same time through the threads in opposite directions, thereby driving the two clamping plates 706 and the rubber pad 707 to move inward to clamp and position the calf. After positioning, according to the actual situation, the hydraulic push rod 701 and the cylinder 709 are controlled to run. The internal technology of the hydraulic push rod 701 and the cylinder 709 is the existing technology. After the hydraulic push rod 701 and the cylinder 709 are running, they respectively drive the auxiliary plate 702 and the arc plate 711 to move up to adjust the appropriate height. After adjustment, the arc plate 711 and the auxiliary plate 702 form two fulcrums, so that the patient's lower limbs are supported at two places. After the patient's lower limbs are positioned, the waste liquid box 906 and the mounting plate 902 at the bottom are pushed to move left and right according to the position of the joints. After the mounting plate 902 is subjected to force, it moves on the limit slider 904 through the adjustment slot 903 at the bottom, so as to move and adjust smoothly, and control the operation of the electric push rod 901. The internal technology of the electric push rod 901 is the existing technology. After the electric push rod 901 is running, it drives the waste liquid box 906 at the output end to move upward, so that the waste liquid box 906 can be consistent with the position of the bone joint, so that the waste liquid and waste generated by the dressing change can directly fall into the waste liquid box 906 without spilling on the ground, and a filter screen plate 908 is arranged inside the waste liquid box 906 through the support block 907. The waste liquid and waste materials can be screened, and the waste liquid box 906 can be pulled up to separate it from the magnetic suction plate 905 on the top of the mounting plate 902. The waste liquid box 906 can then be disassembled for cleaning and replacement. When starting to change medicines, the handle 1010 on the medicine box 1009 is pulled from one side so that the medicine box 1009 is subjected to force and moves on the inner side of the sliding frame 1003 through the sliding block 1004 on the left side.
