[0002] In the severe cold conditions of winter, especially in battlefield environments, combatants often suffer from hypothermia due to inadequate warming measures. If they are not treated with rewarming treatment in time, the consequences will be serious.

[0003] An effective treatment for casualties suffering from hypothermia is usually to wrap them with an insulating blanket to prevent their body temperature from further decreasing, and to quickly transfer them to a warm environment so that their body temperature can quickly return to normal levels. In the prior art, a Chinese invention patent with application publication number CN115175384A proposes a field cold injury first aid electric rewarming blanket, comprising a rewarming blanket body and a self-temperature control device. The rewarming blanket body comprises a PET aluminized film layer, a flexible heating layer and a mesh cloth. The flexible heating layer is arranged between the PET aluminized film layer and the mesh cloth, and the PET aluminized film layer and the mesh cloth are interconnected for heating and heat preservation.
