Problem
Stings from venomous aquatic animals inject thermolabile protein toxins, causing intense pain. Current first aid requires improvisation and delayed heat application, exposing the user to unnecessary risks.
Solution
Portable, waterproof device providing immediate thermal treatment (50–55°C) directly on the sting site. Allows pain relief and emergency care while controlling safety. Designed for consumers and professionals alike.
Technical Principle
- Structure: Silicone body + lid with magnetic switch
- Heat generation: PTC heater + shaped dielectric liquid bag
- Activation: Lid removal → reed switch → PTC power
- Safety: Self-limiting PTC 50–55°C, IP68 waterproof
- Signaling: LED indicators for use feedback
