Hello guys. I've planned to do my project on mechanising stretcher so as to minimise the injuries caused in handling casualties/traumatic patients on stretcher. My intuition was that if we could make a suspension/vibration damping mechanism along with special retractable compartments for holding the person's head, it would be better. Will it work better if I attach a kind of automobile suspension mechanisms on the vertical bars above the stretcher carrier wheels? Please guide me friends.
