The bedding 300 includes a master module 301 and a slave module 302. The master module 301 and the slave module 302 are docked with the slide rail 310 and the slide groove 320, and the slave module 302 and the slave module 302 are matched with the slide rail 310 and the slide groove 320 The main module 301 is provided with a telescopic fixing rod 330 , and the main module 301 detachably arranges the bedding 300 on the fixing chute 120 through the telescopic fixing rod 330 .

Placing the bedding 300 in the storage tank 400 can realize the integration of the auxiliary equipment and the operating bed. When the patient is required to maintain a side lying position during the operation, the medical staff can complete the pick-up and installation of the auxiliary equipment bedding 300 beside the multi-position integrated operating bed of the present invention, without leaving the operating room to receive the bedding 300. In this way, the effect of simplifying the installation and reducing the physical exertion of the medical staff when changing the patient's operating position is achieved.

Further, the first supporting device 100 is near the head side of the patient, and is provided with a headboard 140 for supporting the patient's head in a foldable manner, and a footboard 240 for supporting the feet of the patient is arranged on the calf pad 222 in a foldable manner.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
