when the stop blocks 21 are able to stop the side baffles 4 when the upper-limb protective components 6 are used; when elbows of the patients are required to be fixed and protected, the second supporting rods 612 are rotated for 90 degrees along the first rotating straight-bars 611, and then the second supporting rods 612 are rotated out of the second cavities 610, thereby the second supporting rods 612 are supported on the first bed board 1 and the second bed board 101 for supporting the upper-limb protective components 6; at the same time_ the first rotation connecting vertical bars 67 and the second rotation connecting vertical bars 66 are rotated to drive the first rotation connecting cross-bars 65 to rotate through hinges, thereby the third driven gears 621 are driven to rotate, thereby the first elbow protective components 62 are driven to rotate, thereby the first elbow protective components 62 are rotated for a certain angles, and a preferable rotation scope is 60-90 degrees, and the second rotation connecting vertical bars 66 drive the second rotation connecting cross-bars 64 to rotate through the hinges, thereby the fourth driven gears 631 are driven to rotate, thereby the second elbow protective components 63 are driven to rotate, thereby the second elbow protective components 63 are rotated for a certain angles, and the preferable rotation scope is 60-90 degrees, thereby the first elbow protective components 62 and the second elbow protective components 63 are able to fix and protect the patients' elbows; by arranging the third driven gears 621 and the fourth driven gears 531, the rotation angles of the first elbow protective components 62 and the second elbow protective components 63 are adjustable for different patients; as different patients have different elbows in thicknesses and the component with roots are able to perform the self-locking function, thereby the sliding-down of the patients' elbows due to the gravity of the first elbow protective components 62 and second elbow protective components 63 is avoided, thereby the supporting and protective functions will be effectively performed to patients' elbows and the secondary injury to the patients is avoided; at the same time; the pneumatic massage particles 622 are arranged on surfaces of the first elbow protective components 62 and the second elbow protective components 63, and the extrusion airbags 615 are pressed to transfer gas into the pneumatic massage particles 622 through the main gas circuit connecting tubes 614 and the subsidiary gas circuit connecting tubes 613; in pressing and releasing the extrusion airbags 615, the pneumatic massage particles 622 are able to perform reciprocal expansion and constriction which can massage the patients' elbows; at the same time, as the arrangements of the hand--supported blocks 68, when the patients are required to be put on a drip, the patients are able to slightly hold and/or naturally put palms on the hand-supported blocks 68, thereby the support is provided for hands of the patients when in the infusion, and the roll-over or sliding of the hands due to some non-resistable factors are avoided, thereby some problems like needle dropping or blood back-flow is avoided; when the lower-limb protect components 12 are required to be used to support and protect the lower limbs of the patients, the third supporting rods 123 are rotated for 90 degrees along the second rotation straight-bars 122, thereby the third supporting rods 123 are rotated out of the third cavities 124, thereby the third supporting rods 123 are supported on the first bed board land the second bed board 101 to support the lower-limb protect components 12, and then lower legs (the parts below the knees) of the patients are placed in the arc-shaped grooves 121, thereby the legs of the patients maintain the vertical state, thereby supporting and protective functions are performed to the lower limbs of the patients.
