[0032] The use principle of this utility model:

[0033] 1. The patient lies on his back on the bed. The operator adjusts the bed to various angles by telescoping four hydraulic cylinders and cooperating with the spherical support body, thus providing convenience for examination.

[0034] 2. The patient can move left and right along with the bed by extending or shortening the electric push rod, which further facilitates the examination.

[0035] 3. The movable headrest can be moved left and right along the bed board to accommodate patients of different heights. At the same time, the headrest can be relatively fixed and will not be placed in a messy manner, thereby avoiding increasing the workload of the staff.

[0036] 4. When the patient's condition is serious or it is not suitable for large-scale body movements, first put the foot pedal in contact with the ground, the patient stands on the foot pedal, sits down slowly, moves the board to the patient's back, and the stepper motor keeps the board at the set angle. Then, with the support of the staff, start the electric push rod, pull the bed board to the right, the connecting plate is gradually pulled to the top of the base, and then the inclination angle of the board is slowly reduced. When the patient is in a supine position, pull out the board, make the patient lie on his back on the bed, and place the headrest under the patient's head.

[0037] 5. When the patient needs to adjust the angle of sit-ups during the examination, as described in point 4, move the patient's calves and feet to the top of the base, fix the moving seat and the bed board relative to each other through the positioning bolts, and then adjust the elevation angle of the board by controlling the stepper motor to make the patient's body angle match the examination.
