In the process of turning on one's side, in order to avoid the patient to fall, the both sides of left bed board 4, well bed board 5 and right bed board 8 all are fixed with the safety belt (not shown in the figure), can fix the patient through the safety belt.

The working principle is as follows:

referring to fig. 1, when a patient lies on the folding bed board, the joint of the left bed board 4 and the middle bed board 5 can be repeatedly raised and flattened under the driving of the first swing motor 24, so that the movement of the movable knee joint and the hip joint is realized, and the aim of exercising the lower limbs is fulfilled;

referring to fig. 2, when a patient lies on the folding bed board, the right bed board 8 can rotate anticlockwise around the hinge connected with the middle bed board 5 by the jacking action of the third oil cylinder 21, so that the patient can sit upright or lie half-way;

referring to fig. 3, the patient is fixed on the folding bed board by the safety belt, then the piston rod of the first oil cylinder 27 is withdrawn from the shaft sleeve 29, and the whole bed body (the bed frame 20 and the folding bed board) can rotate anticlockwise around the pin shaft 32 by the jacking action of the second oil cylinder 23, so that the patient stands;

referring to fig. 4, the patient is fixed on the folding bed board by the safety belt, the bolts are taken out, the support columns 26 at the two sides of the bed frame 20 are moved rightwards, the support columns rotate around the respective hinge points and are separated from the corresponding pin shafts 32, and then the hinge joint of the piston rod of the second oil cylinder 23 and the bed frame 20 is released (at this time, the whole bed body is supported on the two lifting frames 16 by the piston rod of the first oil cylinder 27 and the rotating shaft of the worm speed reducing motor 19); finally, the whole bed body can be laterally turned and rotated along the opposite direction of the rotation of the worm speed reducing motor 19 under the driving of the reaction force of the rotation of the worm speed reducing motor 19, so that the lying on the side or the prone position is realized. The lateral position or the prone position can not only avoid bedsore on the buttocks or the back of the patient, but also be beneficial to operations of body position drainage, mechanical ventilation and the like for the patient with acute respiratory distress syndrome. When the lathe bed turns over to reach a preset angle, the brake block 13 is clamped and locked by the brake block 17 driven by hydraulic pressure.

The crane 16 in the above embodiment is composed of a fork carriage (not shown) fixed to the base 18, and a jack 40 (see fig. 8) fixed to the base 18 and hinged to the fork carriage. The height of the crane 16 can be adjusted by the jack 40 in the process of side turning or prostrating the bed body.

Referring to fig. 12, the bedpan 22 adopts the inward-turned edge 22-1 structure, so that the excrement in the bedpan 22 does not fall out due to inclination or inversion during the side-turning or prone lying process of the bed.
