[0014] In the present application, the medical staff moves the base plate 1 to the position of the patient on the hospital bed by pushing the vertical rod 3 and the universal wheel 2, adjusts the patient to a sitting position and helps the patient to move to the position beside the hospital bed, then releases the rotation limitation of the two groups of movable assemblies 41 by the locking assembly 42, controls the two groups of movable assemblies 41 to be simultaneously turned and unfolded in opposite directions, then continues to push the base plate 1 to the patient, lifts the lower leg of the patient upward during the movement, until the vertical rod 3 contacts the frame of the hospital bed, then puts down the lower leg of the patient; at this time, the lower leg of the patient is in contact with the jacking supporting mechanism 8 on the placing rotating plate 6, and the foot of the patient is placed on the upper end of the foot supporting plate 7; Then the two locking assemblies 42 on the front and back sides are controlled to be simultaneously turned in the direction of approaching, so as to drive the supporting cushion plate 9 and the backrest plate 10 to be turned, during the turning process, the inclined surface formed in the inner end of the supporting cushion plate 9 contacts and lifts the hip and thigh of the patient upward, until the inner ends of the two supporting cushion plates 9 on the front and back sides contact each other, at this time, the hip of the patient is completely on the upper end of the two supporting cushion plates 9 on the front and back sides; and the two backrest plates 10 on the front and back sides are also connected and fixed by the movable assemblies 41; at this time, the back of the patient is blocked by the two backrest plates 10 on the front and back sides, and the hip and thigh of the patient are blocked by the two supporting cushion plates 9 on the front and back sides; And at this time, due to the fact that the patient's thighs and buttocks are blocked by the support pad 9, the patient's lower legs and feet are in a relaxed state, and the patient's feet have less downward pressure on the foot support plate 7, the torsion spring 71 controls the foot support plate 7 to always have a tendency to rotate upward, thereby supporting the patient's feet; At this time, the medical staff can pull the base plate 1 away from the patient's bed, so that the patient is separated from the bed, and then move the base plate 1 to the position of the X-ray image examination device, and then release the rotational locking of the backrest plate 10 through the first one-way self-locking assembly, and rotate the backrest plate 10 downward, while rotating the placement plate 6 upward at the same time. At this time, the patient's back moves downward following the backrest plate 10, and the patient's lower legs move upward following the placement plate 6, so that the patient's body posture gradually changes to a lying posture. When the placement plate 6 rotates upward, the second one-way self-locking assembly works to block the downward rotation of the placement plate 6. Then the patient can be examined by X-ray image. When the patient's feet need to be examined, the medical staff controls the lifting assembly to move through the driving assembly, which lifts the patient's lower leg part, so that the patient's lower leg bends upward, which in turn drives the patient's feet to rotate downward and exerts pressure on the foot support plate 7. At this time, the foot support plate 7 rotates downward, and the torsion spring 71 is continuously compressed during the rotation process, until the patient's feet are in a horizontal state. Then the patient's feet can be examined by X-ray image. After the examination is completed, the patient's lower legs and feet are reset by working the lifting assembly through the driving assembly, and the examination is completed. After all the examination items are completed, the base plate 1 is pushed back to the patient's bed until the support pad 9 is above the bed surface. Then the rotational locking of the front and rear two sets of movable assemblies 41 is released by the locking assembly 42, and the movable assemblies 41 on the front and rear sides are pulled outward, so that the support pad 9 is separated from the patient's buttocks and thighs, and then the patient's lower legs are separated from the placement plate 6, and the transfer operation of the patient is completed.

[0015] Through the cooperation of the two sets of movable assemblies 41, the device can conveniently transfer the patient, reducing the additional workload of manually moving the patient to a wheelchair or transfer bed. Through the locking assembly 42, not only the stability of the transfer is ensured, but also the transfer efficiency is improved, and the practicality of the device is improved. Through the cooperation of the driving assembly and the lifting assembly, the device can flexibly adjust the patient's lower leg part for lifting and supporting effect, so that the patient's feet can be kept in a state of being flush with the bed surface, and the image examination of the patient's feet is facilitated.
