[0002] When caring for bedridden patients in hospitals, it is often necessary to move patients from the bed to another bed or examination device when the patient is undergoing pathological examination, has difficulty in moving, or undergoing surgery. This often requires people to lift, support, or drag the patient. This not only fails to ensure the reasonable transfer of the patient, but also causes unnecessary damage to the patient and does not meet many pathological requirements. The medical transfer bed is a transition bed that moves and transfers patients who need surgery or have difficulty in moving, and moves the patient from the bed to the transfer bed, and then from the transfer bed to the operating table or equipment that needs examination or treatment.

[0003] The Chinese invention patent application document with publication number CN106420225A discloses a movable medical conversion bed, including a movable base, a vertical adjustment device and a horizontal conveying device. The vertical adjustment device includes a lifting column and a crossbeam. There are two lifting columns. The lifting columns are vertically fixed on the same side of the movable base. A lead screw is provided in the lifting column. The crossbeam is arranged between the two lifting columns. Both ends of the crossbeam extend into the lifting column and are connected to the lead screw through a lead screw pair. The lead screw is connected to a servo motor. The crossbeam is horizontally arranged on one side of the crossbeam and fixedly connected to the crossbeam. The crossbeam moves the patient from the hospital bed to the conversion bed through a conveyor belt. The conveyor belt is driven by a horizontal drive motor. The servo motor and the horizontal drive motor are both connected to a controller.
