Thermospot Temperature Indicator
|Health Topic||Child mortality|
|Location||Africa, Asia, South America|
Problem being addressed
Hypothermia is a leading cause of infant death in developing countries. Thermometers can be expensive and some require electricity or batteries, which can be a difficult burden on the user. There is currently no low-cost method for continuous monitoring of an infant's body temperature.
Detailed description of the solution
Thermospot is a low-cost, reusable hypothermia indicator designed particularly for use by illiterate mothers. It is a small, flexible sticker with a smiley face to be applied to the infant or child's skin. The LCD screen on the sticker changes color in accordance with the infant's core temperature. It is green with a smiley face when core temperature is between normal limits of between 36.5 and 37.5oC. The color varies from light green with a smiley face to red with a smiley face to all black to indicate severe hypothermia. The color also changes to blue to indicate a fever.
- Designed by: John Zeal in the mid-1990s (original design)
- Manufacturing: worldwide. It can be purchased at Maternova.net
When and where it was tested/implemented
Thermo-spot has been field-tested for more than a decade in several locations including Northern India and Malawi. It is available for sale for less than 8 US cents, and the cost is expected to decrease with mass implementation. This device is now currently available for purchase.
Clinical studies were funded by the Bill and Melinda Gates Foundation and Save the Children. The Johns Hopkins School of Public Health has also contributed to this product's development.
