Design of rehabilitation of lower extremity CPM
Abstract
CPM(continuous passive motion) is a new concept Biology, that is, make strong joints slip theory of continuous passive motion. Mechanism of CPM is the role of continuous passive motion, the accelerated articular cartilage and the surrounding ligaments, win friends and the healing and regeneration of bone.
This article first described the characteristics and application of CPM, an analysis of the rehabilitation device development at home and abroad. Parameters through the analysis of the human lower limb CPM proposed rehabilitation design of the performance parameters. The design of the middle joints of lower limb rehabilitation CPM-driven, and the joint use of worm gear reducer drive worm. In this paper, the main structure and computational stress analysis. Check the motor power, cylindrical worms, bearings and keys, rendering the overall assembly, worm, worm gear, shaft, telescopic rod, such as engineering drawings.
This article describes the rehabilitation of lower limb CPM device of reasonable structure, good process.
