  • Patent number: 7422220
    Abstract: A lightweight, strong, sturdy, and versatile evacuation sled is disclosed. The body of the sled may be manufactured from a single piece of material, stored flat, and folded into its functioning configuration. When folded, the sled has one or more straps that help hold it in its folded configuration and allow maneuvering or carrying the sled. The sled may be readily towed with a towing harness and may be moved down an incline, such as stairs, by means of a rope and belay device. The sled has a low coefficient of friction and is lightweight, allowing the sled to be readily moved and handled without requiring the assistance of multiple people. Additional sleds with foam inserts may be provided to carry equipment such as for life support. The sled may also provide surge capacity for facilities like hospitals, as the sled is designed to be inexpensive and essentially disposable.

  • Patent number: 6942226
    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 the 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.
