AI Technical Summary
In lower limb muscle imaging examinations, some patients require doctors or family members to assist in adjusting the position of their lower limbs due to leg weakness or limited mobility, which increases labor costs and affects the examination progress and imaging quality.
Design an auxiliary positioning device for lower limb muscle imaging examination, including an upper part and a lower part. The device uses a positioning airbag and a flexible connection structure to fix and adjust the thigh and calf. Through the cooperation of inflation and slip ring pull wire, the device achieves stable positioning and posture optimization of the leg.
It reduces leg movement during the examination, improves the accuracy and efficiency of imaging examinations, reduces labor costs, and simplifies examination preparation time.
