[0002] The medical suspended bed is a specific application of solid fluidization technology in the medical field.

[0027] Guide slide blocks are provided on both side surfaces of the threaded cylinder 9, and guide grooves for the guide slide blocks to slide are provided on both side inner walls of the mounting cylinder 5. Under the guiding action of the guide slide blocks, the operation of the motor 8 drives the threaded rod 7 to rotate, so that the threaded cylinder 9 can lift one side of the floating bed body 2 through the second connecting seat 10.
[0028] A sliding opening is provided at the upper end of the sealing cylinder 6, and a load-bearing rod 12 extending into the interior of the sealing cylinder 6 is fixedly connected to the lower surface of the second connecting seat 10 through the sliding opening.
