When the patient needs to turn over, the multi-degree-of-freedom robotic arm 3 moves and changes its own extension structure to adjust its extension angle to achieve its own forward extension or backward retraction, so that the supporting part 4 can extend between the human body and the bed body 1, and then the driving mechanism drives the multi-degree-of-freedom robotic arm 3 to turn around the position where it is hinged with the bed body 1, so as to turn the human body under the premise of supporting the human body. Since bed guard assemblies are provided on both sides of the width direction of the bed body 1, that is, multi-degree-of-freedom robotic arms 3 are provided on both sides of the width direction of the bed body 1, the multi-degree-of-freedom robotic arm 3 located on one side can be driven arbitrarily as needed to assist medical staff in turning over the patient, without the need for the cooperation of multiple medical staff, thereby reducing the difficulty of turning over the patient.
[0027] In a specific embodiment, the bed stopper assembly includes a support seat 2 matched with each multi-degree-of-freedom mechanical arm 3, the support seat 2 is rotatably mounted at the edge position of the bed body 1 along its width direction, and its rotation axis extends in the vertical direction, and the end of the multi-degree-of-freedom mechanical arm 3 without the support portion 4 is hinged on the support seat 2, so that the rotation of the entire multi-degree-of-freedom mechanical arm 3 is realized through the support seat 2, then after the patient is turned over, the support seat 2 is rotated and the multi-degree-of-freedom mechanical arm 3 is rotated to the edge position of the bed body 1 as a whole, so that the multi-degree-of-freedom mechanical arm 3 is parallel to the length direction of the bed body 1, and then the end of the multi-degree-of-freedom mechanical arm 3 not connected to the support seat 2 is abutted against the edge position of the bed body 1, so that the multi-degree-of-freedom mechanical arm 3 itself is used as a bed stopper to prevent the patient from leaving the bed body 1. The entire multi-degree-of-freedom mechanical arm 3 can not only assist medical staff in turning over the patient, but also can be rotated and folded on one side of the bed body 1 after the patient is turned over to be used as a bed stopper, so as to replace the original bed stopper and reduce the occupied space of the entire bed body 1.
[0028] Preferably, the support seat 2 can be rotated manually so that the multi-degree-of-freedom robotic arm 3 can be rotated to the desired position, and a latch assembly is provided between the support seat 2 and the bed body 1, so that after the support is rotated into place, the support seat 2 can be positioned by the latch assembly to prevent the multi-degree-of-freedom robotic arm 3 from rotating when the support seat 2 is in use. Preferably, the support seat 2 can also be rotated by electric control. Specifically, a motor is provided at the bottom wall of the bed body 1, and the output shaft of the motor rotates along the thickness direction of the bed body 1 through the bed body 1 and is connected to the support seat 2, and then the rotation of the support seat 2 is controlled by the motor, and the support seat 2 is positioned by the self-locking function of the motor.
[0029] In a specific embodiment, the bed stopper assembly includes positioning grooves matched with each multi-degree-of-freedom robotic arm 3, the positioning grooves are installed at the edge position of the bed body 1 along its width direction, and are spaced apart from the support seat 2 along the length direction of the bed body 1. The supporting part 4 is embedded in the limiting groove after rotating to the edge position of the bed body 1 with the multi-degree-of-freedom robotic arm 3, so that after the patient is turned over, the multi-degree-of-freedom robotic arm 3 is rotated to make the supporting part 4 embedded in the limiting groove, thereby further positioning the multi-degree-of-freedom robotic arm 3 to avoid rotation or deviation when the multi-degree-of-freedom robotic arm 3 is used as a bed stopper. The structure of the limiting groove is preferably matched with the structure of the supporting part 4 to ensure the stability of the supporting part 4 embedded in the limiting groove.
[0030] In a specific embodiment, the support seats 2 provided in the same bed stopper assembly are staggered along the width direction of the bed body 1, and the support seats 2 and the corresponding limiting grooves are distributed on the same straight line parallel to the length direction of the bed body 1, so as to avoid the multi-degree-of-freedom mechanical arms 3 located on the same side from easily interfering in position when the multi-degree-of-freedom mechanical arms 3 are used as bed stops. Specifically, the same bed stopper assembly is provided with two support seats 2, that is, two multi-degree-of-freedom mechanical arms 3 are provided on the same side of the bed body 1, and the limiting grooves matched with the multi-degree-of-freedom mechanical arms 3 are located between the two support seats 2, and the two limiting grooves are arranged close to each other, so that the two multi-degree-of-freedom mechanical arms 3 form a bed stopper as a whole.
[0031] In a specific embodiment, the support seats 2 provided in the same bed guard assembly are respectively distributed at the positions of the shoulders and hips of the human body, so that the multi-degree-of-freedom robotic arms 3 are correspondingly distributed at the positions of the shoulders and hips of the human body, and then the multi-degree-of-freedom robotic arms 3 can be used to synchronously turn the shoulders and hips of the human body, so that the process of turning the patient over is smoother and reduces the harm to the patient.

Preferably, a connecting rod is provided between the legs of the bed 1, and the winder is installed on the connecting rod, wherein one end of the steel wire rope is hinged on the multi-degree-of-freedom robotic arm 3, and the other end is wound on the winder, so that when the multi-degree-of-freedom robotic arm needs to be extended forward so that the supporting part 4 extends between the human body and the bed 1, the winder unwinds, so that the steel wire rope can be unwound in accordance with the extension of the multi-degree-of-freedom robotic arm 3, and then when the patient needs to be turned over, the winder rewinds, so that the steel wire rope can be retracted with the multi-degree-of-freedom robotic arm 3, and then the patient is turned over through the supporting part 4.
[0034] In a specific embodiment, a pulley assembly is provided at the side wall of the bed 1 along its width direction, and the pulley assembly is located on the side of the support seat 2 away from the bed 1. The portion of the wire rope between the multi-degree-of-freedom robot arm 3 and the winder is passed through the pulley assembly, so that the pulley assembly can be used to allow the wire rope to be wrapped around the outer peripheral side of the bed 1, thereby avoiding friction between the movement of the wire rope and the bed 1, which would affect the retraction and extension of the multi-degree-of-freedom robot arm 3.

Both ends of the support rod 8 are respectively hinged to the corresponding threaded sleeves 7, so that the output shafts of different motors 5 can rotate, thereby driving the change of the position of the threaded sleeve 7 on the threaded rod 6, thereby realizing the angle adjustment between the two adjacent threaded rods 6, thereby realizing the overall retraction and extension of the multi-degree-of-freedom robotic arm 3.
[0036] In a specific embodiment, the multi-degree-of-freedom robotic arm 3 includes a plurality of connecting segments arranged in sequence, a rotating joint composed of a ratchet structure is provided between two adjacent connecting segments, and the rotating joint is equipped with a buckle to fix it. Specifically, the ratchet structure of the rotating joint includes a ratchet and a rocker arm, one end of the rocker arm is connected to the axis of one side of the ratchet, and the other end is connected to a connecting segment, and another connecting segment is connected to the axis of the other side of the ratchet, so as to complete the angle change between the two connecting segments through the ratchet structure, and then after adjustment into place, the relative position between the two connecting segments is fixed by the buckle, and after use, the angle between the two connecting segments is adjusted again by removing the buckle.
