ABSTRACT:
An ambulance cot is provided having a wheeled carriage, a frame for mounting the wheels, a horizontally oriented patient litter supported from the wheeled carriage and variable, pneumatically powered height scissors frame. The pneumatic actuator is designed to give a patient air-ride transportation and an adjustable height litter for lifting a patient from the ground. The patient litter has a pivoting hinge for transporting a patient down stairs. This pivot will allow the stretcher to pivot to a horizontal angle while going down stairs, for patient support and ease of transportation for said operator below. One embodiment has tracks attached over the wheels to provide a more stable and smooth ride as the cot is moved down stairs. Another embodiment comprises a translational trolley configuration. A hand brake is mounted on the patient litter for braking the tank-like motion of the tracks.
