Warmilu LLC’s infant warming blanket uses a nonelectric heat source technology to reduce infant mortality related to hypothermia. The blanket has been engineered to maximize advantages and minimize shortcomings of materials. Components will feature heat retention, lightweight, comfort, and low cost. These components include an outer cover, inner cover, reflective layer, insulation, phase change tubing, and activator discs. The waterproofed outer cover will prevent water from decomposing the reflective layer and damaging the insulation layers. These materials must be lightweight to keep the heat embodiment at a manageable weight.
