A patient treatment device includes an upper cantilever member and a lower cantilever member pivotally coupled to a platform, a bracket pivotally coupled to the front portions of the cantilever members for forming a parallelogrammic device, an elevating transmission device for pivoting the cantilever members up and down relative to the platform, a patient supporting table including a front portion pivotally attached to the bracket, and a tilting transmission device for tilting the patient supporting table between the horizontal position and the tilted working position and for preventing the patient from falling down from the patient supporting table inadvertently.
