The ThermoSpot is a non-invasive hypothermia indicator for infants. It is a single 12 mm flexible plastic disc that sticks directly onto the skin and can remain on for as long as 7-10 days. It is for use in a facility by a clinician, by a community health worker or by a parent. The device changes color when the baby's core body temperature changes, allowing it to be understood even by a non-literate parent. When it is black the child has severe hypothermia. Note that the device has been tested in Malawi, Nepal and India. The simple device comes in a strip of 5. Five strips of 5 are in each pak. Each thermometer is actually re-usable once it is washed with soapy water making it extremely cost-effective. The inventor of the device is currently pursuing CE marking.
These sterile mylar infant warming blankets are used to keep an infant warm by reducing evaporative and connective heat loss. They are used by rescue teams in the U.S., by surgery teams to keep adults from becoming too cold during surgery and by the U.S. military and perhaps most visibly by marathon runners to keep their body heat in once they've stopped running. The technology was actually developed in the 1970s by NASA to deflect heat, but it was soon discovered that the paper thin material could also retain heat as well.
