The present invention relates to a life cradle device for the purpose of inducing therapeutic hypothermia in neonates suffering from birth asphyxia. The device essentially consists of a rigid outer skeleton which could be fitted with removable mattresses containing form stable organic phase change materials effecting instant and sustained cooling. Multiple compartments of different phase change material composition functional at different temperatures are arranged in layers to replicate cooling performances as in conventional cascading systems. The device is also designed to have thermo-chromic indicators with an option of probes for automation control techniques. The device may also be fitted with thermostat controlled infant radiant warmer to automatically switch on when the infant is cooled down below requirement as a safety consideration.
