Ben Welter - Thursday, December 04, 2014

Pluss Polymers of India has won a CII Industrial Innovation Award for its neonate cooler. The MiraCradle, the New Delhi company's first health-care product, is a low-cost passive cooling device for treating newborns suffering from birth asphyxia. It was developed in collaboration with Christian Medical College of Vellore, India.

Birth asphyxia – lack of sufficient oxygen at birth – kills hundreds of thousands of newborns in the developing world each year. Research shows that cooling the body temperature of a newborn suffering from birth asphyxia can help protect the brain from damage. 

The device uses Pluss Polymers' "form-stable" phase change materials, savE FS-21 and FS-29. The manufacturer says the PCMs can be charged in a typical refrigerator.
