A design of stretcher with auxiliary functions of lateral positioning and transferring for immobilized patients

For now, many hospitals that require nurses to move patients by hand from stretchers a hospital bed, so design of stretcher with auxiliary functions lateral positioning and transferring for immobilized patients, which is mechanical mechanism consisted rigid rods, joints sliders, was designed help the between beds reduce their workload. Driven motors, rods can be rotated, stretched or shortened entire bed board archive proper posture position. In this paper, following objectives will achieved: (i) Create schematic describe principles (ii) calculation inverse kinematics, forward dynamics (including energy), PD control in (iii) The motion process simulating using MATLAB (iv) Using create plots angle, torque, position state (v) SolidWorks construct prototype implement simulation (vi) Describe practical application future Extensions mechanism.
