The invention discloses a multi-stage damping device and an emergency treatment bed with the same. The multi-stage damping device comprises a damper cylinder device, a buffer pressure reducing device,a shifting switch device, a hydraulic oil pipe and the like; the damper cylinder device and the buffer pressure reducing device are connected with each other by the hydraulic oil pipe, and the on-offstates thereof are controlled by the shifting switch device; when the multi-stage damping device is mounted, the multiple damping cylinder devices and the buffer pressure reducing device are all mounted on the emergency treatment bed, and the damper cylinder devices are respectively supported and mounted between a bearing part and a moving part of the emergency treatment bed. Compared with the prior art, the multi-stage damping device has the advantages: firstly, adapting to different types and models of emergency treatment beds; the secondly, transporting patients of different weights by damping; thirdly, ensuring th
