Background Art

On March 27, 2020, the State Intellectual Property Office of the People's Republic of China published a patent application document with publication number CN110916722A and invention name "A device for assisting patient limb positioning and adjustment during ultrasonic examination".

Since the ultrasound examination auxiliary patient limb positioning and adjustment device adopts the technical means of a vertical lifting hydraulic column 14, it is not conducive to lowering the minimum height of the bed body, nor is it conducive to increasing the lifting range of the bed body.

Since the ultrasound examination auxiliary patient limb positioning and adjustment device adopts the technical means of the hip lifting rod 11, the pressure pump 12, and the lifting hydraulic column 14, the bed is easy to be displaced, which greatly affects the detection and treatment effect on the patient.

The ultrasound examination auxiliary patient limb positioning and adjustment device is not easy to customize and modify according to actual conditions.

The ultrasound examination auxiliary patient limb positioning adjustment device cannot be disassembled and assembled on the bed, making it inconvenient to transfer the patient to the bed.
