POWERED AMBULANCE COT WITH AN AUTOMATED COT CONTROL SYSTEM

摘要

A powered ambulance cot and methods of raising and lowering the cot as well as loading and unloading the cot are disclosed. The cot includes a support frame and legs, each leg having a wheel. An actuator of an actuation system interconnects the frame and legs, and is configured to effect changes in elevation of the frame relative to the wheel of each of the legs. A control system controls activation of the actuation system, and detects both the actuator at a first location relative to the frame, where the first location is remote from a second location and which situates an end of the actuator that is remote from each wheel closer to the frame, and a presence of a signal requesting a change in elevation of said support frame to thereby cause the legs to move relative to the support frame.

主权项

1. A powered ambulance cot for transporting a patient above a surface, comprising:
a support frame; four legs, each leg having a wheel for supporting the cot on the surface; an actuator of a cot actuation system which interconnects the support frame and a pair of the legs, and effects changes in elevation of the support frame relative to the wheel of each of the legs; and a cot control system operably connected to the cot actuation system to control activation of the cot actuation system, and which detects both the actuator at a first location relative to the support frame, where the first location is remote from a second location and which situates an end of the actuator that is remote from each wheel closer to the support frame, and a presence of a signal requesting a change in elevation of said support frame relative to the wheel of each of the legs to cause the cot actuation system to move the pair of the legs relative to the support frame at a first speed that is different from a second speed at which the cot actuation system moves the pair of the legs relative to the support frame when the end of said actuator is at the second location.
