Gurney system for transporting injured persons

A motorized gurney system for transporting injured persons over rough terrains, comprising:

• a. a suspension frame including first and second supporting plates and a plurality of dampers positioned to absorb vibrations along the x, y, and z axes;
• b. a litter within the suspension frame, the litter having a contoured surface and perimeter side rails to secure an injured person;
• c. a central hub comprising a tire, a motor, a gear train, and wheel in mechanical connection with the gear train;
• and
• d. a directional switch, throttle lever, and brake lever on handles connected to the suspension frame, the levers and switch electronically connected to a motor controller to adjust motion, speed, and braking of the gurney system.

A method of operating a gurney system, the method comprising:

• a. selecting a direction of travel with a directional switch located on handles attached to the suspension frame, the directional switch in electronic communication with a motor controller;
• b. activating a throttle lever on the handles to transmit a control signal from the motor controller to a motor within a central hub, wherein the motor drives a planetary gear system operably coupled to a tire to provide variable torque output for controlled movement of the gurney system over different terrains;
• c. using a braking mechanism within the central hub to selectively disengage the planetary gear system, thereby preventing unintended motion;
• d. absorbing multidirectional vibrations experienced by the gurney system during movement through a plurality of dampers arranged along the perimeter of the suspension frame, each damper configured to reduce oscillations along x, y, and z axes, enhancing stability for the injured person.
