Portable Intelligent Heatable Stretcher Solution for Water Rescue Scenarios

1. Application Scenarios & Challenges

A. Urban Rivers, Lakes, and Reservoirs

  • Challenge: Victims are often out of reach, while currents or obstacles delay rescue boats. Rescuers entering the water risk their own safety.

  • Need: A fast, direct, and safe way to reach and retrieve the person without exposing rescuers.

B. Coastal Waters & Harbors

  • Challenge: Strong waves, tides, and low water temperature cause rapid heat loss in victims. Rescue craft may take minutes to launch, during which survival chances decrease.

  • Need: A device deployable immediately from the shore or pier that can navigate directly to the victim and provide warmth.

C. Recreational Water Areas (beaches, parks, resorts)

  • Challenge: Swimmers or boaters may suddenly experience cramps, fainting, or accidents, leaving them floating helplessly. Lifeguards may struggle to reach them quickly.

  • Need: A rapid-response solution that stabilizes the victim on water and brings them back without delay.

2. Proposed Solution

The Remote-Controlled Heated Foldable Stretcher (HF-Stretcher) addresses these challenges with three core features:

  1. Remote Navigation & Rescue Return

    • Operated directly from the shore via remote control.

    • Navigates autonomously across water surfaces to reach the victim.

    • After securing the victim, it can return to shore carrying the person safely.

  2. Heated Design for Hypothermia Prevention

    • Integrated heating module activated once the victim is on the stretcher.

    • Maintains body temperature in cold water conditions.

    • Reduces risk of hypothermia, especially in early rescue stages before medical care is available.

  3. Foldable & Portable Construction

    • Lightweight and compact, easy to transport and store.

    • Rapid deployment in emergency situations without bulky equipment.

    • Suitable for lifeguards, fire departments, coast guards, and rescue teams.

3. Advantages of the Solution

Advantage Impact
Direct shore-to-victim operation Eliminates delay and reduces risk for human rescuers
Heating function Keeps the victim warm and stabilizes condition before handover to medical staff
Foldable design Portable, space-saving, and quickly deployable
Safe return capability Brings the victim back automatically, avoiding manual towing

Conclusion

The Intelligent Remote-Controlled Heated Foldable Stretcher transforms water rescue operations. By combining mobility, thermal protection, and portability, it ensures faster victim retrieval, minimizes risk to rescuers, and significantly increases survival chances in water emergencies.
