ABSTRACT:
The present invention provides for the conversion of a manual-type ambulance cot to electromechanical usage. In a manual-type cot having a wheeled undercarriage, a cot frame, scissor-action collapsible legs and an extensible member associated with the undercarriage so that extension and retraction of the extensible member raises and lowers the cot frame, the improvement of the present invention includes a linear actuator attached to the extensible member and powered by a high energy density gelcel-type battery. Manual lifting of the cot frame is replaced by electromechanical raising and lowering so that lifting injuries may be avoided.
