[0046] The utility model provides a special kidney dialysis bed with a pedal-type bicycle. When in use, the patient lies on the bed body 2, and then according to the patient's condition, the front and rear adjustment mechanism 4, the left and right adjustment mechanism 6 and the height adjustment mechanism 5 cooperate to drive the leg movable component 9 to be adjusted front and rear, left and right and in height, thereby ensuring that patients of different heights can step on the leg movable component 9, and avoiding the leg movable component 9 being too low to make some patients feel uncomfortable when stepping on it. After the adjustment is completed, the medical staff first puts the straps One end of 10 passes through the two strip grooves on the leg movable component 9, so that under the action of the strap 10, the patient's foot can be tied to the leg movable component 9, and then the Velcro adhesive surface 12 on one side of the strap 10 is pasted with the Velcro adhesive surface 11 on the other side, so that the strap 10 can firmly fix the patient's foot, avoiding the strap 10 from loosening when the medical staff loosens the strap 10.
