The bottom end surface of the fixed block 34 is in movable contact with the top surface of the insert block 29. When the drawer shell 4 returns to the nursing cart 1, the plug block 29 is inserted into the insertion cavity 31 of the partition 14, and the output end face of the fixed card block 34 is a slope, so that the plug block 29 can easily squeeze the fixed card block 34 in the insertion cavity 31, so that the fixed card block 34 moves in the moving groove 33 inside the fixed block 32, so that the fixed card block 34 squeezes several extrusion springs 30, and the extrusion springs 30 have elastic deformation, so that the fixed card block 34 clamps and fixes the plug block 29, so that when the nursing cart 1 shakes, the drawer shell 4 is stable in the nursing cart 1, preventing the drawer shell 4 from moving when the nursing cart 1 shakes, maintaining its stability, and ensuring that the drawer shell 4 does not shake during the movement of the nursing cart 1.

[0031] The working principle is as follows: when in use, the medical staff pushes the nursing cart 1 into the operating room, limits and fixes the push wheels of the nursing cart 1, cleans their hands, and changes to new medical gloves. When medical supplies are needed, the medical staff steps on the pedal 20, which drives the rotating column 19 to rotate, and simultaneously presses the pressure sensor 22. The pedal 20 drives the pressure rod 25 to move in the hydraulic cylinder 21, and the pressure sensor 22 transmits the signal to the controller 27. The controller 27 controls the motor 9 to work, and the motor 9 drives the ball screw 10 to rotate. The ball screw 10 cooperates with the screw slider 11, and the screw slider 11 drives the displacement sensor 23 to move synchronously, so that the displacement sensor 23 can detect the moving distance of the drawer shell 4. When the displacement sensor 23 reaches the maximum moving distance of the drawer shell 4, the displacement sensor 23 transmits a signal to the controller 27. The controller 27 controls the motor 9 to stop working, so that the drawer shell 4 stops moving, and the screw slider 11 drives the limit sliders 8 at both ends to move stably in the limit sliding cavity 7, so that the screw slider 11 stably drives the drawer shell 4 to move, and the drawer shell 4 drives the drawer blocks 3 at both ends to move in the drawer limit blocks 2, so that the drawer shell 4 can be automatically and stably pushed out of the nursing cart 1, and the medical gloves of the medical staff do not need to contact the handle of the drawer shell 4, thereby reducing the risk of cross-infection when storing and retrieving medical equipment, etc. Medical staff do not need to manually operate the drawer shell 4, which simplifies the process of taking medical items and can significantly improve work efficiency and response speed.

[0032] When the medical supplies are in the drawer cavity 5 and the drawer shell 4 is inside the nursing cart 1, the fixed electric contact 13 and the movable electric contact 12 are in contact with each other, the battery pack 24 supplies power to the ultraviolet lamp 26, and the sealing strip 17 fits tightly on the sealing cavity 15 and the inclined surface 16 of the partition 14, so that the ultraviolet lamp 26 can disinfect and sterilize the medical supplies in a closed environment, and the medical supplies taken out from the medical equipment library are directly placed in the drawer cavity 5, and the drawer cavity 5 is in a closed environment, and the ultraviolet lamp 26 can also disinfect and sterilize the medical supplies. The ultraviolet lamp 26 has a strong bactericidal effect and can effectively kill bacteria, viruses and other microorganisms, thereby ensuring the medical supplies. The medical supplies reach a high level of sterility before use and are disinfected with ultraviolet light in a closed environment, effectively preventing contamination from the external environment. This allows the medical supplies to remain sterile during storage and transportation, helping to avoid the introduction of contamination sources during use and reducing the risk of cross-infection when storing and accessing medical devices. By disinfecting and sterilizing in a closed environment, the possible presence of microorganisms on the surface of medical supplies is greatly reduced. Disinfection measures are particularly important in treatments with extremely high sterility requirements, and the ultraviolet lamp 26 provides a uniform disinfection effect, ensuring that all medical supplies exposed to ultraviolet light can be effectively treated. The ultraviolet lamp 26 in a sealed environment has less impact on medical staff.

[0033] After the operation is completed, the hydraulic cylinder 21 returns the pressure rod 25 and the pedal 20 to their original positions. The pedal 20 is stepped on again, the pressure sensor 22 is pressurized again, the motor 9 is reversed, and the drawer shell 4 is returned to the nursing cart 1. The drawer cavity 5 inside the drawer shell 4 is sealed and sterilized again. When the drawer shell 4 is returned to the nursing cart 1, the plug block 29 is inserted into the plug cavity 31 of the partition 14, and the output end face of the fixed card block 34 is an inclined surface, which makes it convenient for the plug block 29 to fix the fixed card block 34 in the plug cavity 31. The fixed card block 34 is squeezed to make the fixed card block 34 move in the movable groove 33 inside the fixed block 32, so that the fixed card block 34 squeezes several extrusion springs 30. The extrusion springs 30 have elastic deformation, so that the fixed card block 34 clamps and fixes the insertion block 29, so that when the nursing cart 1 shakes, the drawer shell 4 is stable in the nursing cart 1, preventing the drawer shell 4 from moving when the nursing cart 1 shakes, maintaining its stability, and ensuring that the drawer shell 4 does not shake during the movement of the nursing cart 1.
