EasyLift Stretcher Sketch Model 10.8.09 Blue B Our Concept Assisted-lift ambulance stretcher Reduce back injuries to EMTs 16 million patients transported to hospitals each year in the US Benchmarking Ferno 35A Stryker PowerPRO


  1. EasyLift Stretcher Sketch Model • 10.8.09 Blue B

  2. Our Concept  Assisted-lift ambulance stretcher  Reduce back injuries to EMTs  16 million patients transported to hospitals each year in the US

  3. Benchmarking Ferno 35A Stryker PowerPRO hello Cheap (~$3,000) Expensive (~$14,000) Lightweight Bulky No lift-assist Lifts 700lbs with ease

  4. Considerations  Collapsed height constraint  Speed and smoothness of lifting  Manual over-ride  How much load assist is appropriate?  80th percentile male weight= 210 lbs Need to balance these parameters

  5. Demonstration  In current configuration:  200 lbs of lifting force  2.5” diameter piston  11” of piston travel for 30” of vertical lift

  6. Lessons Learned  Several orientations for linkages  Piston can be moved, re-oriented, adjusted, etc.  Pedal is a comfortable control  Need robust locking mechanism when raised
