This device can be used when the dressing needs to be changed for children with leg injuries. The staff can insert the appropriate partition plate 3 into the placement trough 2 according to the medicine that needs to be changed, and then place the medicine on the placement trough. Within 2, the device can then be taken to the patient's bed, the installation platform 1 can be clamped on the hospital bed, and then the patient's legs can be lifted and placed on the leg resting platform 7, and the device can be placed according to the patient's condition. The leg length is used to adjust the position of the right leg placing platform 7. Pull the right guide groove plate 5 to drive the right first return spring 8, connecting plate 6, leg placing platform 7, mounting frame 91, guide tube 92, The second return spring 93 and the rubber ball 94 move to the left. When the right rubber ball 94 moves to the left and does not fit with the slot of the guide base 4, the right rubber ball 94 will move forward under the action of the guide base 4. , the second return spring 93 on the right side is compressed. When the right rubber ball 94 moves to the left to fit into the slot of the guide base 4, the right rubber ball 94 will move toward the right side under the action of the second right return spring 93. After the movement is reset, when the position of the right guide groove plate 5 is adjusted, the right rubber ball 94 can be engaged with the guide seat 4 to fix the position of the right guide groove plate 5 to prevent the right guide groove plate 5 from being 5 movement, the guide groove plate 5 on the left side can also be adjusted in the same way. The third return spring 102 is initially stretched. When the patient's legs are placed on the leg placing table 7, the leg placing table 7 will be moved. 7 drives the connecting plate 6 to move downward, and the first return spring 8 is compressed. When the hole of the connecting plate 6 fits with the limiting column 104, the limiting column 104 and the hand lever 103 move inward under the action of the third return spring 102. move, the limiting column 104 moves inward to block the connecting plate 6. When the leg placing platform 7 moves downward, the downward movement of the leg placing platform 7 also drives the connecting rod 124, the torsion spring 125, and the limiting rod 126. and the second contact block 123 moves downward. The second contact block 123 moves downward until it contacts the first contact block 122 and then continues to move. Under the action of the first contact block 122, the second contact block 123 will rotate. The rotation of the two contact blocks 123 drives the limit rod 126 to rotate, and the torsion spring 125 deforms. The rotation of the limit rod 126 can cooperate with the leg placement table 7 to clamp the patient's legs, preventing the patient's legs from being damaged due to pain during dressing change. After leaving the leg placement table 7, the staff can then take out the medicine in the placement slot plate 2 and change the dressing for the patient. After the dressing change is completed, pull the handle rod 103 to drive the limiting column 104 to move outward to loosen the connecting plate 6. The third return spring 102 is stretched, and then the staff can pull the connecting plate 6 to drive the leg placing platform 7 to move upward to reset, the first return spring 8 is reset, and the leg placing platform 7 moves upward to drive the connecting rod 124 and torsion spring 125 , the limit rod 126 and the second contact block 123 move upward, and the second contact block 123 is no longer resisted by the first contact block 122. Under the action of the torsion spring 125, the limit rod 126 and the second contact block 123 rotate and reset, and the limit rod 126 and the second contact block 123 rotate and reset. The position lever 126 rotates and resets and no longer cooperates with the leg placement table 7 to clamp the patient's legs, and then the patient's legs can no longer be placed on the leg placement table 7, thus completing the entire dressing change process. The staff can then remove the installation platform 1 from the hospital bed.

Example 2

On the basis of Embodiment 1, as shown in Figures 1 and 8, an auxiliary disinfection mechanism 11 is also included. The auxiliary disinfection mechanism 11 can spray disinfectant to disinfect the patient.
