Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in FIGS. 1 to 5: the supporting mechanism is fixed on the base 13, and the bed frame 1 is supported on the supporting mechanism through the turnover mechanism and the side-turning mechanism. Wherein:

the supporting mechanism is composed of upright posts 4 respectively hinged on two sides of a base 13 and lifting frames 11 respectively fixed on two ends of the base 13; a supporting oil cylinder 14 is hinged between each upright post 4 and the base 13, a supporting seat 15 is fixed on the lifting frame 11 on the left side, and a limiting groove 10 is fixed on the lifting frame 11 on the right side. The turnover mechanism is composed of a pin shaft 3 and a turnover oil cylinder 5, wherein the pin shaft 3 is respectively fixed on two sides of the bed frame 1 and supported on the corresponding upright post 4, and the turnover oil cylinder 5 is hinged between the base 13 and the bed frame 1. The side-turning mechanism is composed of a supporting oil cylinder 2 and a worm speed-reducing motor 6 which are fixed on the back of a bed frame 1, a piston rod of the supporting oil cylinder 2 is inserted into a supporting seat 15, a rotating shaft of the worm speed-reducing motor 6 extends into a limiting groove 10, the piston rod is coaxial with the rotating shaft, and a limiting rod 9 is fixed on the rotating shaft.

In order to increase the stability and facilitate the piston rod to be inserted into the bearing seat 15 smoothly, a guide sleeve 16 fixed on the back of the bed frame 1 is arranged between the bearing seat 15 and the supporting cylinder 2; in order to increase the rigidity of the rotating shaft, a bearing seat 7 is fixed on the back of the bed frame 1.

In order to facilitate the rapid supporting of the pin shaft 3, a U-shaped groove (not shown in the figure) matched with the pin shaft 3 is formed at the left end of the upright post 4; in order to avoid accidents caused by the pin shaft 3 falling out of the U-shaped groove, a pin hole (not shown) is formed at the top end of each upright post 4, and a pin (not shown) for blocking the notch of the U-shaped groove is arranged in each pin hole.

In order to simplify the structure, the lifting frame 11 consists of a fork shearing frame 11-1 fixed on a base 13 and a jacking oil cylinder 11-2 hinged between the fork shearing frame and the base 13.

In order to further improve the safety of the side turning of the lathe bed and ensure that the lathe bed can be stable and static at any angle, a brake pad 8 is fixed on a rotating shaft of the worm speed reducing motor 6, and a hydraulic brake block 12 which can clamp the brake pad is fixed on a lifting frame 11 at the right end.

When in use, the integral bed board or the folding bed board can be fixed on the bed frame 1.

The working principle is as follows:

referring to fig. 3, the patient is fixed on the bed board (not shown) by the safety belt (not shown), then the piston rod of the supporting cylinder 2 is withdrawn from the supporting seat 15, and the whole bed body (the bed frame 1 and the bed board) can rotate counterclockwise around the pin shaft 3 by the jacking action of the jacking cylinder 5, so that the patient stands;

referring to fig. 4, the patient is fixed on the bed plate by the safety belt, the bolts are taken out, the upright columns 4 positioned at two sides of the bed frame 1 are moved rightwards, the upright columns 4 rotate around respective hinge points and are folded and stored on the base 13 together with the supporting oil cylinder 14 after being separated from the corresponding pin shafts 3, and the hinge joint of the piston rod of the jacking oil cylinder 5 and the bed frame 1 is released (at this time, the whole bed body is supported on the two lifting frames 11 by the piston rod of the supporting oil cylinder 2 and the rotating shaft of the worm speed reducing motor 6 together); finally, the whole lathe bed can be laterally turned and rotated along the opposite direction of the rotation of the worm speed reducing motor 6 under the driving of the reaction force of the rotation of the worm speed reducing motor 6, so that the lateral lying or the prone lying can be 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 8 is clamped and locked by the hydraulically-driven brake block 12.
