Autonomous and Manual Hybrid Stretcher: Ground or Hover Mobility
By Ronen Kolton Yehuda (Messiah King RKY)
Introduction
In the evolving landscape of emergency response and medical transport, innovation must prioritize both speed and adaptability. The Hybrid Autonomous Stretcher is a revolutionary device that transforms the concept of patient mobility—capable of functioning either autonomously or with manual control, and equipped with dual-mode movement: traditional ground driving and advanced hovering.
Ideal for ambulances, hospitals, military rescue operations, disaster zones, and smart cities, this stretcher is designed to handle challenging environments while ensuring the safety and dignity of patients.
Core Features
1. Dual Mobility System: Drive or Hover
Ground Wheels Mode: Standard or all-terrain wheels enable smooth transportation in hospitals, urban areas, or emergency vehicles.
Hover Mode (Optional): Magnetic levitation or ducted fan systems allow short-distance hovering over debris, stairs, or difficult terrain—ideal for battlefield or disaster recovery zones.
2. Hybrid Operational Modes
Autonomous Mode: Equipped with AI, sensors, and obstacle detection, the stretcher can navigate hallways, elevators, or open fields with pre-programmed destinations.
Manual Mode: Healthcare providers or rescuers can override controls using a handlebar or remote device, allowing traditional stretcher use when necessary.
3. Smart Patient Support
Vital Monitoring: Embedded systems can track pulse, oxygen, and motion during transport.
Shock Absorption Platform: The mattress system adjusts to reduce movement shock and enhance patient stability.
Smart Locking System: Automatically stabilizes the stretcher when stationary.
Applications
Hospitals and emergency rooms
Ambulance and air ambulance integration
Military medevac units
Disaster relief zones and remote rescues
Smart hospitals and autonomous healthcare systems
Conclusion
The Hybrid Autonomous Stretcher is more than just a medical transport tool—it's a leap toward intelligent, compassionate, and adaptable healthcare logistics. With its blend of hover and drive technology, and its balance between autonomy and human control, this device ensures that help always arrives—swiftly and securely.
