  • Patent number: 8273044
    Abstract: A traction splint device for providing aid to a person suffering from a broken or fractured lower extremity. The device generally includes a collapsible shaft adapted to be positioned alongside a leg of a patient, a first support connected to a first end of the shaft, and a second support connected to a second end of the shaft. The first support is adapted to be positioned forwardly of a lower end of the leg and includes a center brace having a notch. A plurality of stabilizing straps traverse the shaft and are adapted to constrain the leg. At least one of the straps is adapted to wrap around the notch of the center brace to secure a lower end of the leg and at least one of the straps is adapted to extend through an opening of the second support to secure an upper end of the leg.

  • Patent number: 7740298
    Abstract: A human transporting system for efficiently removing an injured person out of water. The human transporting system generally includes a handle, a pair of straps attached to the handle, a pair of sliding loops attached to the straps forming looped portions for receiving the wrists of an injured human, and a pair of biasing members attached between the handle and the sliding loops. The looped portions receive the wrists of the injured human and the user pulls the injured human from the water by pulling upon the handle which tightens the looped portions upon the wrists. Once the injured human is pulled out of the water, the handle is lowered thereby allowing the biasing members to loosen the looped portions about the wrists.

  • Patent number: 7631380
    Abstract: A wheeled attachment system for efficiently attaching to a spine board to allow the spine board to be easily maneuvered over various surfaces (e.g. flat surfaces, stairs, etc.). The wheeled attachment system generally includes a front support, a pair of wheel assemblies extending from opposing sides of the front support, a pair of side supports extending from the front support adjacent the pair of wheel assemblies and at least one strap extending from the pair of side supports. The side supports and the front support define a cavity adapted to receive an end of a spine board, wherein the strap is adapted to secure the pair of wheel assemblies about the spine board. A pair of extension members interconnect the pair of wheel assemblies with the front support so that a center rotational axis of the pair of wheel assemblies is vertically offset with the front support.
